The Frosty Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On a hot summer day, the shop sold 8 more sundaes than

sineoko [7]

Answer:

The number of sundaes sold are 36.

Step-by-step explanation:

The cost of each sundae is $2 and the cost of each banana splits is $3.

The number of sundae sold be "x" and banana split be "y".

Thus, the total amount spent is,

= $2x+3y$

The total amount spent is given to be $156. Thus,

156 = $2x+3y$

It is also given that, the shop sold 8 more sundaes than banana splits. In equation form,

$x = y+8$

$y = x-8$ ,

Inserting this value of y in above equation, we get,

156 = $2x+3(x-8)$ = $5x-24$

$180 = 5x$

Thus, x = 36 = number of sundae sold.

Find an equation of variation in which y varies jointly as x and z and inversely as the product of w and p,

pentagon [3]

The equation of variation in which y varies jointly as x and z and inversely as the product of w and p is y=0.5(xz/wp).

Given that variable y varies jointly as x and z and inversely as the product of w and p,where y=7/28 where x=7,z=4,w=7 and p=8.

We are required to find the equation of variation.

To solve this problem we must apply the following procedure:

1) We have that y varies jointly as x and z and inversely as the product of w and p. Therefore we can write the following equation,where k is the constant of proportionality:

y=k(xz/wp)----------1

Now we have to solve for the constant of proportionality as done under:

k=ywp/xz-------------2

Using the values in equation 1.

k=(7/28)(7)(8)/(7)(4)

=0.5

Using all the values in the equation 2.

y=0.5(xz/wp)

Hence the equation of variance is y=0.5(xz/wp).

Question is incomplete.The following values should be included:

y=7/28 where x=7,z=4,w=7 and p=8.

On a field trip, there are 5 adult chaperones for every group of 20 students. There are 150 people in total on the trip. What pe

denis23 [38]

Answer:

80% of the people on the trip are children.

Step-by-step explanation:

To determine the percentage of the people on the trip that are children,

First, we will determine how many of the people are children.

From the question,

There are 5 adult chaperones for every group of 20 students, that is, out of 25 people, 5 are adult chaperones and 20 are students.

From the question, there are 150 people in total in total.

Let the number of children be x

If there are 20 students (children) in 25 people

Then, there will be x children in 150 people

x = (150 × 20) / 25

x = 120

Hence, there are 120 children.

To determine the percentage of the people on the trip that are children,

we will divide the number of children by the total number of people and then multiply by 100%

Number of children = 120

Total number of people = 150

∴ The percentage of the people on the trip that are children is

(120/150) × 100% = 0.8 × 100% = 80%

Hence, 80% of the people on the trip are children.
