Answer:

B)80.67 feet per second

Step-by-step explanation:

Given: Driving at a rate of 55 miles/hour

1 mile = 5280 feet

1 hour = 60 minutes = 3600 seconds

Now we have to convert miles per hour in feet per seconds

= (55*5280) / 1*3600

= 290400/3600

= 80.67 feet per second.

Therefore, answer is B)80.67 feet per second

A right come has a slant height of 6 and a radius of 4 what is the surface area?

likoan [24]

The SA formula to find a right cone is area of the base x 1/2 (perimeter)(slant height)

To find the area of the base you do radius squared x pi
Radius=11
So 121pi is area of the base

Perimeter=circumference of the circle
So perimeter=24pi

So 121pi x 1/2 (12pi)(6)
12 x 6=72pi/2=36pi

121pi x 36pi= 4356pi

Answer: 4356pi

(w_2)(w+7) multiply and simplify your answer

alexira [117]

If there is no number in between sets of numbers, it's going to be multiplication.
So (w+2) x (w+7)

w+2, well, evaluates into w+2.
w+7 is w+7.

We'll use the FOIL method for this.
FOIL stands for:

First
Outer
Inner
Last

Let's start with the first terms. Multiply them.
So: w * w.
Combine both w's, and you get $w^2$ .

Now multiply the outer terms.
w * 7 = 7w.

Then the inner terms. 2 and w.
2 x w = 2w.

So our current numbers are: $w^2$ , 7w, and 2w.
We can add 7w and 2w together.
7w + 2w = 9w.

Now multiply the last terms.
2 x 7 = 14.

So, this simplifies to $w^2+9w+14$
Hope this helped!

College student makes decorative Styrofoam Lions and Husky's which she sells each year. Each one uses 8 oz of Styrofoam and take

Travka [436]

Answer:

She should make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is $1109

Step-by-step explanation:

The given information are;

The volume required to make each lion = 8 oz

The time it takes to make each lion = 35 minutes

The amount of profit each lion brings = $2.50

The volume required to make each Husky = 12 oz

The time it takes to make each Husky = 20 minutes

The amount of profit each Husky brings = $3

Let the number of lion Styrofoam cups she makes = x

Let the number of Husky Styrofoam cups she makes = y

Therefore, we have;

x × 35 + y × 20 = 9650..........(1)

x × 8 + y × 12 = 3840.............(2)

Dividing equation (2) by 8 and making x the subject, we get;

x × 8/8 + y × 12/8 = 3840/8

x + 4/3·y = 480

x = 480 - 4/3·y

Substituting the value of x in equation (1) gives;

(480 - 4/3·y) × 35 + y × 20 = 9650

16800 - 80/3·y = 9650

y = 268.125

x = 480 - 4/3·y = 480 - 4/3×268.125 = 122.5

Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is therefore given by the following equation;

The maximum profit = 122 × 2.5 + 268 × 3 = $1109.

How many pounds of chamomile tea that costs $18.50 per pound must be mixed with 18 lb of orange tea that costs $12.23 per pound

Rasek [7]

Answer:

The amount of chamomile tea that has to be used in order to obtain a mixture that costs $14.32 per pound is 8.997 pounds

Step-by-step explanation:

In order to find out the amount of chamomile tea that must be used in the mixture to obtain a 14.32 $ per pound, we can use an weighted average where the price points for each kind of tea are the weights and "c" is the amount of chamomile that we have to use in order to obtain the price per pound that we want. So we have:

(18.5*c + 12.23*18)/(c + 18) = 14.32

18.5*c + 220.14 = 14.32*(c+18)

18.5*c + 220.14 = 14.32*c + 257.76

18.5*c - 14.32*c = 257.75 - 220.14

4.18*c = 37.61

c = 8.997 lb
