There are 950 students at Hanover High School. The ratio of the number of freshmen to all students is 3:10. The ratio of the num

-Dominant- [34]

Hi there! Since the ratios of students at Hanover High School are in different scales, we need to scale them up! First, let's take the ratio 1:2. This can be scaled up to 5:10. Now, combine the two ratios to find the ratio of freshmen to sophomores. 3:10 + 5:10 = 8:10. The remaining number is 2, since 8 + 2 = 10, so the ratio of freshmen to sophomores is 2:10!

Hope this was helpful!

If you had a right triangle with legs measuring 40 yards and 100 yards long,

tia_tia [17]

9514 1404 393

Answer:

Step-by-step explanation:

For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...

c² = a² +b²

Solving for c, we have ...

c = √(a² +b²)

c = √(40² +100²) = √(1600 +10000) = √11600

c ≈ 107.70 . . . . yards

The length of the hypotenuse is about 108 yards.

irina1246 [14]

Answer:

Sam's description = $3x+3$ , Kim's description = $5x-7$

Step-by-step explanation:

Given:

Kim and Sam were each given the same pair of numbers.

Sam's description of the two numbers was:

The larger number is 3 more than three times the smaller number.

Kim's description of the two numbers was:

Five times the smaller number decreased by 7 is the larger number.

Question asked:

Which equation represents the situation?

<u>Solution:</u>

Let smaller number = $x$

According to Sam's description of the two numbers, the equation will be:-

Larger number = 3 more than three times the smaller number

= $3x+3\ (eq1)$

According to Kim's description of the two numbers was, the equation will be:-

Larger number = Five times decreased by 7

= $5x-7\ (eq2)$

By equating both equation:-

$5x-7=3x+3\\ \\ Subtracting\ both\ sides\ by \ 3x\\ \\ 5x-3x-7=3x-3x+3\\ \\ 2x-7=3\\ \\ Adding\ both\ sides\ by\ 7\\ \\ 2x-7+7=3+7\\ \\ 2x=10\\ \\ Dividing\ both\ sides\ by\ 2\\ \\ x=5$

Smaller number = $x$ = 5

Larger number = $3\times5+3=15+3=18$

Therefore, equations represents the situation are $3x+3$ and $5x-7$
