Answer:

40 7th Graders

Step-by-step explanation:

First you add all of the students to get 25. Then you divide 100 by 25 to get 4 (this is gonna be your multiplier) now multiply each part of the ration by 4, and you get 60 6th graders and 40 7th graders :D.

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 222 inches and a height of 666 inch
rewona [7]

Based on the given parameters about old cone, the height of the new cone is 12 inches

<h3>Equivalent ratio</h3>

Old cone:

  • Radius, r = 2 inches
  • Height, h = 6 inches

New cone:

  • Radius, r = 4 inches
  • Height, h = h

equate ratio of radius to height in old and new cone

2 : 6 = 4 : h

2/6 = 4/h

cross product

2 × h = 6 × 4

2h = 24

h = 24/2

h = 12 inches

The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?
Katarina [22]

Answer:

10%

Step-by-step explanation:

We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.  

We will use markup % formula for our given problem.

\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100

\text{Markup percentage}=\frac{429-390}{390}\times 100

\text{Markup percentage}=\frac{39}{390}\times 100

\text{Markup percentage}=\frac{1}{10}\times 100

\text{Markup percentage}=10

Therefore, markup is 10% of cost.
