Answer:

15

Step-by-step explanation:

Add the total of miles Marisa is going to drive; 200 + 220 = 420

Next, divide the total miles by the average miles Marisa can travel on one gallon of gas; 420 / 28 = 15

(Hope this helps!)

Answer:

y = 15

Step-by-step explanation:

-1/3 y -6 = -11

Add 6 to each side

-1/3 y -6+6 = -11+6

-1/3 y = -5

Multiply each side by -3

-1/3 y * -3 = -5*-3

y = 15

Check

-1/3 *15 -6 = -11

-5 -6 = -11

-11=-11

In the lower triangle, one of the angles of which is 45 degrees, we know:

In the triangle, the side facing the angle 45° is √2 / 2 times the hypothenuse.

Thus ;

[tex]10 = hypothenuse \times \frac{ \sqrt{2} }{2} \\ [/tex]

[tex]hypothenuse \times \frac{ \sqrt{2} }{2} = 10 \\ [/tex]

Multiply sides by 2

[tex]hypothenuse \times \sqrt{2} = 2 \times 10[/tex]

Divide sides by √2

[tex]hypothenuse = \frac{2 \times 10}{ \sqrt{2} } \\ [/tex]

[tex]hypothenuse = \frac{ \sqrt{2} \times \sqrt{2} \times 10 }{ \sqrt{2} } \\ [/tex]

[tex]hypothenuse = 10 \sqrt{2} [/tex]

The common side of the triangles is hypothenuse for both.

[tex]hypothenuse \times \cos(60) = x[/tex]

[tex]10 \sqrt{2} \times \frac{1}{2} = x \\ [/tex]

[tex]x = \frac{2 \times 5 \sqrt{2} }{2} \\ [/tex]

[tex]x = 5 \sqrt{2} [/tex]

Answer:

x = 10 feet

Step-by-step explanation:

Given that,

The  area of his bathroom is 100 square feet.

We need to find the one side of the square bathroom.

Let the side be x. The area of a square is given by :

[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]

So, the side of the square bathroom is 10 feet.

Answer:

Mary needs $0.18 more

Step-by-step explanation:

12 mangoes = $13.20

For every 5 mangoes that he bought he got one mango free

This means he bought 10 mangoes (5 mangoes + 1 free mango the first time and 5 mangoes + 1 free mango the second time)

If James paid $13.20 for 10 mangoes, then

Each mango cost = $13.20 / 10

= $1.32

Each mango cost $1.32

Mary wants to by 4 mangoes from the same shop.

Total cost of 4 mangoes = $1.32 × 4

= $5.28

She only has $5.10.

How much more money does she need

Amount needed more = Total amount required - total amount available

= $5.28 - $5.10

= $0.18

Mary needs $0.18 more

Answer:

For example, if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.

Answer:

[tex]\dfrac{27}{100}[/tex]

Step-by-step explanation:

The number [tex]0.27[/tex] can be attained by the following expression

[tex]0.27=\dfrac{k27}{k100}[/tex]

Where

[tex]k[/tex] = any positive positive integer.

Let us take the minimum ratio

[tex]0.27=\dfrac{1\times 27}{1\times 100}[/tex]

[tex]=\dfrac{27}{100}[/tex]

where [tex]k = 1[/tex]

So, the probability estimate in ratio form is [tex]\dfrac{27}{100}[/tex].

Answer:

21 birds and 7 dogs

Step-by-step explanation:

Represent Birds with B and Dogs with D

[tex]B + D = 28[/tex] ----- Total Animals

A bird has 2 legs and a dog has 4, so:

[tex]2B + 4D = 70[/tex] ---- Legs

Required

Solve for D and B

Make D the subject in the first equation

[tex]D = 28 - B[/tex]

Substitute 28 - B for D in the second

[tex]2B + 4(28 - B) = 70[/tex]

[tex]2B + 112 - 4B = 70[/tex]

Collect Like Terms

[tex]2B - 4B = 70 - 112[/tex]

[tex]-2B = -42[/tex]

Solve for B

[tex]B = -42/-2[/tex]

[tex]B = 21[/tex]

Recall that: [tex]D = 28 - B[/tex]

[tex]D = 28 - 21[/tex]

[tex]D = 7[/tex]

Hence, there are 21 birds and 7 dogs

Answer:

SAS

Step-by-step explanation:

We have 2 sides that are congruent and the angle between them

We can use SAS ( side angle side) to prove congruency

Answer:

(a) The coordinates of the inflection point are (1; 8) and, being the value of a less than zero, then these coordinates indicate the maximum of the function.

(b) The y-intercept has a value of 6

(c) The coordinates of the x-intercepts have a value of x=3 and x=-1

Step-by-step explanation:

You know y= -2*(x-1)² + 8

(a) Every quadratic function can be expressed by the canonical form:

f(x)=y= a*( x- h)² + k

where a is the principal coefficient and the ordered pair (h; k) are the coordinates of the vertex of the parabola.

The quadratic function will have a maximum or minimum value at the vertex. If a> 0, the parabola is concave, that is, it will have its branches upwards, therefore the vertex will indicate the minimum of the function. But if a <0 the parabola is convex and the vertex will indicate the maximum of the function.

Comparing the given equation with the canonical form of a quadratic function you can see that:

Then, the coordinates of the inflection point are (1; 8) and, being the value of a less than zero, then these coordinates indicate the maximum of the function.

(b)  The y-intercept arises from evaluating the function at x = 0. So, in this case:

y= -2*(0-1)² + 8

Solving:

y= -2*(-1)² + 8

y= -2*1 + 8

y= -2+8

y= 6

The y-intercept has a value of 6

(c)   The roots or coordinates of the x-intercepts arise from evaluating the function at y = 0. So, in this case:

0= -2*(x-1)² + 8

Solving:

-8= -2*(x-1)²

[tex]\frac{-8}{-2} =(x-1)^{2}[/tex]

4= (x-1)²

√4= |x-1|

⇒ 2=x-1 → 2+1=x → 3=x

⇒ -2=x-1 → -2+1=x → -1=x

The coordinates of the x-intercepts have a value of x=3 and x=-1

Answer:

3948 members

Step-by-step explanation:

SInce a is the initial amount, a = 2000. b represents growth factor, and the amount increases by 12% every year, so b = 1.12. Since you want to find the value in 6 years, x= 6. Therefore your equation is y = 2000 • 1.12 ^ 6. Plug it into your calculator and you get y =  3947.64, and since they are people you round up to 3948 members.

he put away 91% of the candy for later because 100 divided by 53 is 1.89 and 1.89 multiplied by 48 equals 90.72 which rounds up to 91. hope you get a good grade!

If we divide £42 in the ratio of 1:5 so it comes 7 and 35.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 42 \times 1 \div (1 + 5)[/tex]

= 7

And

[tex]= 42 \times 5 \div (1 + 5)[/tex]

= 35

Therefore we can conclude that If we divide £42 in the ratio of 1:5 so it comes 7 and 35.
