There are 4 strawberries, 3 blueberries, 7 bananas and 4 oranges. Find is the ratio of oranges choose the ratio that is the simplest form

Answers

The ratio of oranges to the fruits is 2 : 9 in the simplest form.

We are given that we have:

4 strawberries

3 blueberries

7 bananas

and  4 oranges.

So, the total fruits we have are:

Total fruits = 4 + 3 + 7 + 4

Total fruits = 7 + 11

Total fruits = 18 fruits

Now, we need to find the ratio of oranges in these fruits.

Ratio refers to the representation of one number with respect to the other number.

So, the ratio will be:

Ratio = 4 : 18

Simplifying the ratio, we get that:

Ratio = 2 : 9

Therefore, the ratio of oranges to the fruits is 2 : 9 in the simplest form.

The length of students' college careers at Anytown University is known to be normally distributed with a mean length of 5.5 years and a standard deviation of 1.75 years. What percent of students have college careers lasting between 2 and 9 years?

Answers

The per cent of students who have college careers lasting between 2 and 9 years is 95%.

Given that, the normally distributed with a mean length of 5.5 years and a standard deviation of 1.75 years.

What is a normal distribution?

The normal distribution is a continuous probability distribution that is symmetrical around its mean with most values near the central peak.

Let x be the length of student's college careers.

\mu = 5.5 years

\sigma = 1.75 years

A percentage of students have college careers lasting between 2 and 9  years.

P(2<=x<=9)=P (2-5.5<=x-5.5<=9-5.5)

P(2<=x<=9)=P (-3.5<=x-5.5<=3.5)

=P (-3.5/1.75<=(x-5.5)/1.75<=3.5/1.75)

We know if x =-=N (4.6^2)

Then x-\mu/\sigma =-= Z (0.1)

=P(-2<=Z<=2)

=0.95

Percentage = P(-2<=Z<=2)*100

=95%

Therefore, the per cent of students who have college careers lasting between 2 and 9 years is 95%.

if Dr. I.M. smart mixes 30mL of acid into 50 ml of a 20% acid solution, what is the quantity and concentration of the final solution?

the final solution is ______ mL with ______ % concentration

thank you so much for the help!

Answers

The final solution which Dr. I.M. smart made is 80 ml with 50% acid concentration.

What is concentration ?

Concentration determine how much percentage of a certain type of liquid is there in the whole mix of two or more than two liquids.

According to the given question Dr. I.M smart mixes 30ml of acid in 50ml of 20% acid solution.

Let us assume that in  50ml of 20% acid solution x ml is acid

∴ (20/100)×50 = x.

(1000/100) = x

x = 10ml.

Now he adds 30 ml of acid into this so total acid in this concentration is (10+30) ml = 40 ml  and remaining concertation has 40 ml of other quantity.

∴ The total solution is now of 80 ml.

So the final solution is 80ml with 50% acid and 50% other concentration.

Answer: Simplify the expression ( 7 a 5 b 6 ) 4 is = 2401 [tex]a^{20}[/tex] [tex]b^{24}[/tex]

Step-by-step explanation:

Given data,

Expression is = (7 a 5 b 6) 4

So, we can write,

Expression is = (7a^(5)b^(6))^(4)

                       = [tex][7a^{5} b^{6} ]^{4}[/tex]

Use the power rule [tex](ab)^{n}[/tex] = [tex]a^{n} b^{n}[/tex] to distribute the exponent.

We can use this formula,

Apply the product rule to  [tex][7a^{5} b^{6} ]^{4}[/tex]

                                      = [tex][7a^{5} ]^{4}[/tex] [tex][b^{6} ]^{4}[/tex]

Apply the product rule to  [tex]7a^{5}[/tex]

                                       = [tex]7^{4} [a^{5} ]^{4} [b^{6} ]^{4}[/tex]

Raise 7 to the power of 4,

                                        =  2401 [tex][a^{5} ]^{4} [b^{6}]^{4}[/tex]

Multiply the exponents in [tex][a^{5} ]^{4}[/tex]

Apply the power rule and multiply exponents,   [tex][a^{m} ]^{n}[/tex] = [tex]a^{mn}[/tex]

                                        = 2401 [tex]a^{5*4}[/tex] [tex][b^{6} ]^{4}[/tex]

Multiply 5 by 4,

we can write,

                                        = 2401 [tex]a^{20}[/tex] [tex][b^{6} ]^{4}[/tex]

Multiply the exponents in  [tex][b^{6} ]^{4}[/tex]

Apply the power rule and multiply exponents,  [tex][a^{m} ]^{n}[/tex] = [tex]a^{mn}[/tex]

                                        = 2401 [tex]a^{20}[/tex] [tex]b^{6*4}[/tex]

Multiply 6 by 4,

we can write,

                                       = 2401 [tex]a^{20}[/tex] [tex]b^{24}[/tex]

Therefore,

Simplify the expression ( 7 a 5 b 6 ) 4 is = 2401 [tex]a^{20}[/tex] [tex]b^{24}[/tex].

Answers

I assume the equation is

[tex]x \, dy - (y^2 - 4y) \, dx = 0[/tex]

since separating variables leads to

[tex]x\,dy = y(y-4) \, dx[/tex]

[tex]\dfrac{dy}{y(y-4)} = \dfrac{dx}x[/tex]

for which the condition that [tex]x>0[/tex] is actually relevant, as opposed to the simpler differential equation

[tex]x \, dx - (y^2-4y)\, dy = 0 \implies y(y-4) \, dy = x \, dx[/tex]

(though it's a bit more work to solve for [tex]y(x)[/tex] in this case)


That the slope [tex]\frac{dy}{dx}[/tex] is non-zero tells us that

[tex]\dfrac{dy}{dx} = \dfrac{y(y-4)}x \neq 0 \implies y\neq0 \text{ and } y \neq 4[/tex]

Integrate both sides.

[tex]\displaystyle \int \frac{dy}{y(y-4)} = \int \frac{dx}x[/tex]

On the left, expand into partial fractions.

[tex]\displaystyle \frac14 \int \left(\frac1{y-4} - \frac1y\right) \, dy = \int \frac{dx}x[/tex]

[tex]\dfrac14 (\ln|y-4| - \ln|y|) = \ln|x| + C[/tex]

With the given initial value, we find

[tex]y(1) = 2 \implies \dfrac14 (\ln|2-4| - \ln|2|) = \ln|1| + C \implies C = 0[/tex]

so the particular solution is

[tex]\dfrac14 (\ln|y-4| - \ln|y|) = \ln|x|[/tex]

By definition of absolute value, with the initial condition of [tex]0 < y=2 < 4[/tex] and the condition [tex]x>0[/tex], we can remove the absolute values.

[tex]\dfrac14 (\ln(4-y) - \ln(y)) = \ln(x)[/tex]

Solve for [tex]y[/tex].

[tex]\ln\left(\dfrac{4-y}y\right) = 4 \ln(x) = \ln\left(x^4\right)[/tex]

[tex]\dfrac{4-y}y = \dfrac4y - 1 = x^4[/tex]

[tex]\implies y(x) = \dfrac4{1 + x^4}[/tex]

Then

[tex]10y\left(\sqrt2\right) = \dfrac{40}{1 + \left(\sqrt2\right)^4} = \boxed{8}[/tex]

On the off-chance you meant the other equation I suggested, we find

[tex]\displaystyle \int y(y-4) \, dy = \int x \, dx[/tex]

[tex]\displaystyle \frac{y^3}3 - 2y^2 = \frac{x^2}2 + C[/tex]

[tex]y(1) = 2 \implies \dfrac83 - 2\cdot4 = \dfrac12 + C \implies C = -\dfrac{35}6[/tex]

Solving for [tex]y(x)[/tex] involves picking the right branch of the cube root that agrees with [tex]y(1)=2[/tex]. With the cube root formula, we find

[tex]y(x) = 2 - \xi(1 - i\sqrt3) - \dfrac1\xi (1+i\sqrt3)[/tex]

where

[tex]\xi = \dfrac{2\sqrt[3]{4}}{\sqrt[3]{3x^2 - 3 + \sqrt{9x^4 - 18x^2 - 1015}}}[/tex]

With a calculator, we find

[tex]10y\left(\sqrt2\right) \approx 18.748[/tex]

A father is three times as old as his son. After 4 years, his age will be 4 times his son's age 2 years ago. Find their present age. ​

Answers

The present age of the father is 36 and the present age of the son is 12 years.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that a father is three times as old as his son. After 4 years, his age will be 4 times his son's age 2 years ago.

Let the present age will be "F" and "S". The equations will be solved as:-

F = 3S

F + 4 = 4 ( S - 2 )

F + 4 = 4S - 8

3S + 4 = 4S - 8

S = 12 years

F = 3S

F = 3 x 12 = 36 years

Therefore, the present age of the father is 36 and the present age of the son is 12 years.

a mechanic charges $150 per hour,plus the cost of parts to fix your car if the parts cost $257 write an equation to model the total cost use h as the variable for the number of hours in rakes the mechanic to fix your car and c as the cost

Answers

The Equation representing the charge to be to paid to mechanic is -

c = 150h + 257.

What is Equation modelling?

Equation modelling is defined as a method for deriving a mathematical relation from a mathematical statement taking into consideration the variables defined and the relations between them.

Given is a mechanic who charges $150 per hour. He also charge the cost of parts to fix the car.

Assume that the mechanic worked for 'h' hours and 'c' represents the total cost of repair. Extra cost of parts is $257.

If the mechanic works for 'h' hours, then the money received by the mechanic will be → $150 x h.

The equation representing the above situation can be written as -

c = $150 x h + Extra parts charge.

c = 150h + 257

Therefore, equation representing the charge to be to paid to mechanic is -   c = 150h + 257.

A cooler is filled with four liters of water and it is marked every 0.2 l and each bottle holds 4/9 of a liter for for water bottles are filled how much water is left in the cooler

Answers

Complete question :

A cooler contains 4 L of water. The cooler has marks on it at every 0.2 L. Water bottles are filled with water from the cooler, and each bottle holds approximately 4/9L. After 4 water bottles are filled, between which two marks is the water level in the cooler? Show your work.

Answer:

2.2 - 2.4 Litre

Step-by-step explanation:

Capacity of cooler = 4L

Marking on cooler = every 0.2L

Capacity of bottle = 4/9 L

Number of bottles filled = 4

Total volume filled = (4/9) * 4 = 16/9 L = 1.78L

Volume of water left in tank :

(4 - 1.78)Litre

= 2.22 litres

Since, the tank is marked at 0.2 L interval ; the water level will be between 2.20 to 2.40 litres

THANK YOU SO MUCH FOR THE HELP!!!!!!!!!!!!!

Answers

Answers:

Domain:  [tex]-2 \le \text{x} \le 2[/tex]Range:  [tex]-2 \le \text{y} \le 2[/tex]The relation   is not    a function

========================================================

Explanation:

The domain is the set of possible x values. The left-most point occurs when x = -2, while the right-most point is when x = 2. Therefore, x is between -2 and 2 in which we write [tex]-2 \le \text{x} \le 2[/tex]. Both endpoints are included.

-----------

The range is the set of possible y values. The possible y values are in the interval [tex]-2 \le \text{y} \le 2[/tex] since y = -2 is the smallest y can get, and y = 2 is the largest it can get. Visually we look at the lowest and highest points respectively to find the span of y values.

-----------

This relation is not a function because it fails the vertical line test.

It is possible to pass a single vertical line through more than one point on the curve. For example, the vertical line through x = -1 goes through the points (-1,1) and (-1,-1)

Phrased another way: The input x = -1 leads to more than one output.

A function is only possible if each input in the domain leads to exactly one output.

Simplify the following expression: (-5)(-3)(4) (1 point)
-65
-60
60
65

Answers

Answer: The following expression: (-5)(-3)(4) = 60

Step-by-step explanation:

Given that,

The following expression is : (-5)(-3)(4)

Let us assume,

These values represented by X1, X2, X3    

Let us assume,       X1 = -5

                                X2 = -3

                                X3 = 4

So, the following expression is: (X1)(X2)(X3)    

                                                    (-5)(-3)(4)

This values using by multiplication,

So, we can write,

                                  = (X1)(X2)

                                  = (-5)(-3)                    [sign (-) (-) = (+)]

                                  = 15

Therefore, X1X2 values = 15

We can solve X3 value,

                                = (X1)(X2)(X3)

                                = 15 (X3)

 Replace X3 value,

                                = 15(X3)

                                = 15 (4)

                                 = 60

Therefore, (X1)(X2)(X3) = 60

The following expression: (-5)(-3)(4) = 60

Answers

Answer:

y = 112 and z = 30

Step-by-step explanation:

Since the y angle and the 68 angle are same side exterior angles, they add up to 180

68+y = 180

y = 112

If we take (5z -82) angle's alternate interior angle, we get:

5z-82+112 = 180

5z = 150

z = 30
