Find the percent the first number is of the second:
c
5 ft, 37.5 ft

Answers

Answer:

13 1/3%

Step-by-step explanation:

37.5/5=7.5

100/7.5=13.33333

13.333333= 13 1/3

Answer: 13 1/3%

13.33% is the percent the first number is of the second number.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

We need to find the percent of the first number is of the second.

The first number is 5 feet and the second number is 37.5 feet.

We want what percent 5 feet is of 37.5 feet,

To find this we need to divide 5 feet/37.5 feet

We get 0.1333333 feet.

Now we have to multiply 0.1333333  by 100 as it is a hundredth part.

0.1333333 × 100 = 13.33333%

We can test that by doing 13.33333% of 37.5 (or .1333333 x 37.5) and we get 5 feet.

Hence, 13.33% is the percent the first number is of the second number.

Rectangle A and rectangle B are similar.
Rectangle A has a length of 6.2 centimeters
and a width of 5.6 centimeters. Rectangle B
has a length of 21.7 centimeters. What is the
perimeter of rectangle B?

Answers

Answer:

82.6 cm

Step-by-step explanation:

First, we make a proportion:

6.2(length A) / 5.6(width A) = 21.7(length B) / x(width B)

Cross multiply: 6.2 * x =( 21.7) * (5.6)

Divide both sides by 6.2: x = 19.6

So the width of rectangle B is 19.6. Now lets find the perimeter

19.6 + 19.6 + 21.7 + 21.7 = 82.6 cm

Four members from a 12 ​-person committee are to be selected randomly to serve as​ chairperson, vice-chairperson,​ secretary, and treasurer. The first person selected is the​ chairperson; the​ second, the​ vice-chairperson; the​ third, the​ secretary; and the​ fourth, the treasurer. How many different leadership structures are​ possible?

Answers

Answer:

11880 ways

Step-by-step explanation:

We can solve this problem in two ways. I'm going to show you how to do both.

We have 12 persons and are to choose a chairperson, a vice chairperson, secretary and a treasurer. So we are picking 4 members our of 12 persons.

From this 12, when we pick out one member, we are left with 11members. From 11, if we pick out another one, we have 10 left. From 10, if we pick out another member we have 9 left.

Such that

12 x11 x10x 9= 11880

These are the total different leadership structures possible.

Another way to solve this is by permutation method.

nPr

12!/(12-4)!

= 12!/8!

= 11880 ways

Lealani has 24 scoops of high-fiber chimp food.

a. How many scoops of high-protein food should Lealani add to the mix if she wants to give it to baby chimps? Recall that baby chimps need 40% high-fiber food and 60% high-protein food.

b. How many scoops of high-protein food should Lealani add to the mix if she wants to give it to adult chimps? Recall that adult chimps need 60% high-fiber food and 40% high-protein food.​

Answers

Answer: a = 14.4 scoops; b = 9.6 scoops

Step-by-step explanation:

a.) 40% of the high fiber scoops is 9.6. We need to figure out how much of the high protein she needs, so we would subtract the 9.6 from 24 and get 14.4.

b.) Solved the same as the first problem but with different numbers. 60% of her high fiber food is 14.4, so subtract that from 24 and you get 9.6.

Please help me I don’t get this Write the equation of the line that is parallel to y=3x-2 and goes through the points (-4,2)

Answers

Alright so answer is y=3x+14

Since you need to find a PARALLEL line to y=3x-2, you already know that the incline is 3x because otherwise the two lines would intersect somewhere.

So for your new equation you now have y=3x+b, so you only need to find b. To do so you’ll need to replace all other variables by numbers with the point that is given and then isolate b.

You can do so with the point that is given to you (-4, 2). You replace y by 2 since the point is (x,y) and replace x by -4.

You now have
2=3(-4)+b
2=-12+b
2+12=b
14=b

You now have your equation: y=3x+14

Snow Dome Ski Resort has 65 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resort has 74 inches of snow. Currently it is snowing there at a rate of ½ inch per hour.

a) Write equations that show the amount of snow at each resort as a function of the number of hours of snow.

b) If the snow continues at this rate, when will Snow Dome have more snow than Mt. Winterpark? Show your solution process clearly.

Answers

Answer:

(a)

Snow Dome Ski: y = 65 + t

Mt. Winterpark: y = 74 + ½t

(b) Hours greater than 18

Step-by-step explanation:

Given

Snow Dome Ski

Base Snow = 65in

Rate = 1 in per hour

Mt. Winterpark

Base Snow = 74 in

Rate = ½ in per hour

Solving (a): Equation for both

To determine the amount of snow (y) at time (t) for any of the two, we make use of:

y = Base Snow + Rate * t

For Snow Dome Ski:

y = 65 + 1 * t

y = 65 + t

For Mt. Winterpark

y = 74 + ½ * t

y = 74 + ½t

Solving (b): When snow dome will have more snow.

To solve this, we set the following inequality

Snow Dome Ski > Mt. Winterpark

This gives:

65 + t > 74 + ½t

Collect Like Terms

t - ½t > 74 - 65

½t > 9

Multiply both sides by 2

t > 18

This implies that the snow at Snow Dome Ski will be more than the snow at Mt. Winterpark after 18 hours.

After 18 hours means, hours greater than 18 which could be 19, 20, 21.....
