Your question is missing formula for m which is given as;

formula for $m= \frac{p^3}{90}$

Answer:

a.the inverse of the function is $p=\sqrt[3]{90m}$ .

b.p=12 (thousands)

Step-by-step explanation:

Given Data:

Formula for $m= \frac{p^3}{90}$ , where m is the total number of months it takes to produce p tennis rackets (in thousands).

Required:

a. Find the inverse of the function.

b. How many tennis rackets will be produced in 20 months? Round your answer to the nearest whole tennis racket.

Solution:

a.Inverse of the function:

$m= \frac{p^3}{90}\\\\multiply\ both\ sides\ by\ 90\ we\ get\\p^3=m*90\\\\p^3=90m\\\\taking\ cube\ root\ we\ get\\\\p=\sqrt[3]{90m}$

the inverse of the function is $p=\sqrt[3]{90m}$ ........Eq1

b. How many tennis rackets will be produced in 20 months?

put m=20 in Eq1, we get

$p=\sqrt[3]{90*20}\\\\p=\sqrt[3]{1800}\\\\p=12.16$

If we round the answer to nearest whole tennis racket we get p=12 (thousands)

thus, in 20 moths 12 (thousands) tennis rackets will be produced

Hector has a floor plan showing his new house. On the floor plan, his bedroom is 3 inches wide and 3

Nat2105 [25]

Question:

Hector has a floor plan showing his new house. On the floor plan, his bedroom is 3 inches wide and 3 1/2 inches long. The scale of the floor plan is 1/4 inch = 1 foot. What is the actual length of Hector’s room?

Answer:

The actual length of Hector room is 14 foot

Solution:

Given that, On the floor plan, his bedroom is 3 inches wide and $3\frac{1}{2}$ inches long

The scale of floor plan is given as:

$\frac{1}{4} \text{ inch} = 1 \text{ foot }$

Therefore,

$1 \text{ inch } = 4 \text{ foot}$

To find: Actual length of floor

From given question,

$length = 3\frac{1}{2} \text{ inches}$

Converting the mixed fraction to improper fraction,

$length = \frac{2 \times 3 + 1}{2} = \frac{7}{2} \text{ inches }$

Since, 1 inch = 4 foot

$\frac{7}{2} \text{ inches } = \frac{7}{2} \times 4 \text{ foot } = 14 \text{ foot }$

Thus actual length of Hector room is 14 foot

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger

Paha777 [63]

Answer:

the burgers be 3 and fries be 2

Step-by-step explanation:

The computation is shown below:

Let us assume burgers be x

And, the fries be y

Now according to the questiojn

1.25x + 0.50y = $4.75

1.50x + 0.99y = $6.48

Now multiply by 1.2 in the first equation

1.50x + 0.6y = $5.70

1.50x + 0.99y = $6.48

-0.39y = -0.78

y = 2

Now put the value of y in any of the above equation

1.25x + 0.50(2) = $4.75

x = 3

Hence, the burgers be 3 and fries be 2
