Answer:

Step-by-step explanation:

perimeter = semicircle (x2) + parallelogram side (x2)

= 1/2 π 12 (x2) + 15 (x2)

= 37.7 + 30

= 67.7

15. Solve for the specified variable:<br> -<br> х<br> +<br> 7 8<br> - 10; for y.

Andreyy89

Answer:

$y=80-\frac{8x}{7}$

Step-by-step explanation:

15). Given equation is,

$\frac{x}{7}+ \frac{y}{8}=10$

Multiply the equation by 8,

$8(\frac{x}{7}+ \frac{y}{8})=10\times 8$

$\frac{8x}{7}+y=80$

Subtract $\frac{8x}{7}$ from both the sides of the equation,

$\frac{8x}{7}+y-\frac{8x}{7}=80-\frac{8x}{7}$

$y=80-\frac{8x}{7}$

Therefore, value of the variable 'y' will be,

$y=80-\frac{8x}{7}$

Solve for x for #5 and 6

Alex777 [14]

Answer:

In 5:

UM and MS are equal since the diagonals US and VT have perpendicularly bisected each other.

So,15=6x-3

15+3=6x

18=6x

3=x

In 6:

ET=TC

8=x-4

8+4=x

12=x

How many ways are there to fill either the pitcher or catcher field position (but not both) from among the 25 players (leaving t

Artemon [7]

Using the permutation formula, it is found that there are 600 ways to fill the pitcher and catcher positions.

The order is important, as one player is the pitcher and the other is the catcher, hence the <em>permutation formula </em>is used to solve this question.

<h3>What is the permutation formula?</h3>

The number of possible permutations of x elements from a set of n elements is given by:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

2 players are taken from a set of 25, hence the number of ways is given by:

$P_{(25,2)} = \frac{25!}{23!} = 600$ .
