Find the area of the composite figure.

dmitriy555 [2]

Answer:

B. $200.5 \: {m}^{2}$

Step-by-step explanation:

Area of the composite figure = Area of square with side length 12 m + Area of semicircle with radius (12/2= 6) 6 m

$= {(12)}^{2} + \frac{1}{2} \pi {r}^{2} \\ \\ = 144 + \frac{1}{2} \times 3.14(6)^{2} \\ \\ = 144 + \frac{1}{2} \times 3.14 \times 36 \\ \\ = 144 + 56.52 \\ \\ = 200.52 \: {m}^{2} \\ \\ \approx \: 200.5 \: {m}^{2}$

Write an expressionNick has x toy race cars. This is one third of what Bob has. How many toy race cars does Bob have?

natita [175]

Given:

Nick has x toy race cars. This is one-third of what Bob has.

So, the number of Nick toys = one-third of what Bob has.

Let the Bob has y toys

So, we can write the following expression:

$x=\frac{1}{3}y$

Solve for y, multiply both sides by (3):

$y=3x$

So, the answer will be:

Bob has (3x) toy race cars.

Help me plssssssssss

elena55 [62]

Answer:

<h2><u>4 quarters, 10 dimes</u></h2>

Step-by-step explanation:

x + y = 14 --> x = 14 - y

$0.10x + $0.25y = $2.00, or 10x + 25y = 200

- we can plug this value for x from the first equation into the second:

10(14 - y) + 25y = 200

140 - 10y + 25y = 200

140 + 15y = 200

15y = 60

y = 4 --> 4 quarters ($0.25 x 4 = $1.00)

if y = 4, then x = 14 - y --> x = 10 --> 10 dimes (0.10 x 10 = $1.00)

matches the second equation where these add up to $2.00
