Convert 48 2/5 into a decimal

Answer:

45

Step-by-step explanation:

2/3 of 45 is 30

630 gallons of 90% antifreeze has to be mixed.

Sum of values of two solutions = Value of mixture  

90% =0.9 unit value and amount x we get value 0.9x

10%= 0.1 unit value and amount 90 we get value =0.1*90=9

total mixture =0.80 value x+90 we get value 0.8*(x+90)

0.9x + 9 = 0.8(x + 90)  

0.9x + 9 = 0.8x + 90 x 0.8

0.9x – 0.8x = 72 – 9

0.1x = 63

x = 630

Hence, 630 gallons of 90% antifreeze has to be mixed.

The average rate of change of f(x) = 1/(x + 12) on the given interval is expressed as: [tex]\frac{-1}{19(h + 19)}[/tex]

Given the function, f(x) = 1/(x + 12), the average rate of change of f(x) on the interval, [7, 7 + h], can be calculated using the formula:

Average rate of change = f(b) - f(a)/b - a.

a = 7

f(a) = f(7) = 1/(7 + 12) = 1/19

b = 7 + h

f(b) = f(7 + h) = 1/(7 + h + 12) = 1/(h + 19)

Plug in the values into the average rate of change formula

Average rate of change = 1/(h + 19) - 1/19 ÷ 7 + h - 7

Average rate of change = [19 - (h + 19)]/19(h + 19) ÷ h

Average rate of change = (19 - h - 19)/19(h + 19) × 1/h

Average rate of change = -h/19(h + 19) × 1/h

Average rate of change = -1/19(h + 19) × 1/1

Average rate of change = [tex]\frac{-1}{19(h + 19)}[/tex]

Therefore, the average rate of change of f(x) = 1/(x + 12) on the given interval is expressed as: [tex]\frac{-1}{19(h + 19)}[/tex].

Answer:

-7 + 10 = 3

Step-by-step explanation:

The hospital can get 4.15 milligrams from these three companies.

A linear equation is one in which the highest power of any variable is not more than 1. A linear equation in 2 variables can be solved by substitution method, if we have two simultaneous equations.

Here, we know that

Company A's supply of medicine = 1.7 mg

also, company A's supply = 2( B's supply - C's supply)

⇒ 1.7 = 2( B - C)

⇒ 1.7 = 2B - 2C .... (1)

Moreover, we are given that

A's supply = C's supply + 0.9

⇒ 1.7 = C + 0.9

⇒ 1.7 - 0.9 = C

⇒ 0.8 = C

Now, substituting the value of C in (1), we get,

1.7 = 2B - 2(0.8)

1.7 = 2B - 1.6

1.7 + 1.6 = 2B

⇒ B = 3.3/2

B = 1.65

Thus, the total supply from all three companies is (1.7 + 1.65 + 0.8) = 4.15 mg

The equation of the circle that passes through the given points and has its center lying on this line 2x + y = 7 is equal to x² + y² - 10x + 6y - 6 = 0.

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Assuming the center of this circle lies at (h, k), then we have the following expressions that models the distance from the center of the given circle:

(h - 7)² + (k - 3)² = (h - 11)² + (k - (-1))²

(h - 7)² + (k - 3)² = (h - 11)² + (k + 1)²

(h - 7)² - (h - 11)² = (k + 1)² - (k - 3)²

(h - 7 + h - 11)(h - 7 - h + 11) = (k + 1 + k - 3)(k + 1 - k + 3)

(2h - 18)(4) = (2k - 2)(4)

8h - 72 = 8k - 8

8h - 8k = 64

h - k = 8         .......equation 1.

Since (h, k) lies at 2x + y = 7, we have:

2h + k = 7       .......equation 2.

Solving eqn. 1 and eqn. 2 simultaneously, we have:

h - k = 8

2h + k = 7

3h = 15

h = 15/3

h = 5.

For the value of k, we have:

h - k = 8

5 - k = 8  

k = 5 - 8

k = -3.

Next, we would determine the radius of this circle:

Radius, r² = (h - x)² + (k - y)²

Radius, r² = (5 - 7)² + (-3 - 3)²

Radius, r² = (-2)² + (-6)²

Radius, r² = 4 + 36

Radius, r = √40.

Now, we can write the equation of this circle:

(x - h)² + (y - k)² = r²

(x - 5)² + (y - (-3))² = 40

(x - 5)² + (y + 3)² = 40.

x² - 5x - 5x + 25 + y² + 3y + 3y + 9 - 40 = 0

x² - 10x + 25 + y² + 6y - 31 = 0

x² - 10x + y² + 6y - 6 = 0

x² + y² - 10x + 6y - 6 = 0.

Step-by-step explanation:

each messages cost Layla 10 cents. Which means that 151 x 0.10= 15.10

Answer:

Step-by-step explanation:

Given,

No. of text messages for $4.70 = 47

So, no. of text messages for $1.00 = [tex]\frac{47}{4.7}[/tex]

Therefore,

No. of text messages for $15.10

= [tex]\frac{47}{4.7}[/tex] × 15.10

Hence,

Answer:

The Length is 56 feet

Step-by-step explanation:

w + w + 8 + w + 8 + w = 208  (two sides have a width of w and 2 sides have the length of 8 + w)

Combine the w/s and the 8's

4w + 16 = 208  Subtract 16 from both sides of the equation

4w = 192  Divide both sides by 4

w = 48  The width is 48 feet.  That means that the length is 8 feet longer or 56 feet.

Check:

48 + 48 + 56 + 56 = 208

208 = 208

Answer: 8√3.

Step-by-step explanation:

First, look for any perfect squares that can fit into 192 snugly.

If we look for factors of 192, we can discover that the largest perfect square that can fit into it is 64 (and 3).

The √ of 64 is 8.

The √ of 3 cannot be simplified any further.

Thus, leaving us with our answer of 8√3.

Answer: c.

Step-by-step explanation: An Irrational Number is a real number that cannot be written as a simple fraction

By using addition and subtraction, we get that, John cannot eat half that is 4 / 8 of the pizza the next day.

Let the total pizza be 1.

On the first day, the fraction of pizza that John ate = 3 / 8

On the next day, the fraction of pizza that John ate = 1 / 4

Total pizza that John ate till now will be calculated using addition:

3 / 8 + 1 / 4

3 / 8 + 2 / 8

5 / 8

Now, the pizza that is left will be calculated by subtracting the pizza that he ate from the total pizza that he had.

1 - 5 / 8

8 / 8 - 5 / 8

3 / 8

We can see that the half pizza is not left.

So, he cannot eat half that is 1 / 2 or 4 / 8 pizza the next day.

Therefore, by using addition and subtraction, we get that, John cannot eat half that is 4 / 8 of the pizza the next day.

-2      -11

-1        -8

0       -5

1        -2

2         1

Slope = Change in y values/ Change in x-values

          = -8 --11/-1--2 = 3

Also -5 --8/0--1 =3, -2--5/1-0 = 3, 1--2/1-0 = 3, 4-1/3-2 = 3

So the slope is constant and is m = 3.

y-intercept is the y-value corresponding to when x = 0.

Here, when x = 0, y = -5.

So the y-intercept, c = -5

The equation for the linear function in slope-intercept form is,
