Answer:

A ≈ 12.57

Step-by-step explanation:

You have to take the formula: A = πr^2

1) Plug in what you know: A = π•2^2

2) π = 3.14 and 2^2 = 4

3) Multiply to get: 12.56637

4) Round

A ≈ 12.57

Complete the missing value in the solution to the equation.

snow_lady [41]

Answer:

y = − 1

Hope this helps!

Step-by-step explanation:

Alright so this is our equation:

y − 3 = 2 ( x − 1 )

We will substitute:

x = − 1

So now our equation looks like this:

y − 3 = 2 ( −1 − 1 )

Now we will get rid of the parentheses:

y − 3 = − 2 − 2

Solve the left side:

y − 3 = − 4

Now add 3 on both sides to find out what y is:

y − 3 = − 4

+3 +3

Add:

y = − 1

Yay! We found our answer! Nice job everyone!

Mjhs is refinishing a basketball court and decided to paint everything shown below blue. How many square feet will be painted bl

SashulF [63]

Answer:

<h2>Mjhs needs 189.25 square feet of blue paint, approximately.</h2>

Step-by-step explanation:

As you can observe in the image attached, the basketball court is a composite figure formed by a rectangle and half of a circle.

The rectangle has dimensions of 10 feet by 15 feet. The circle has a diameter of 10 feet.

The expression of this composite area would be

$A= w \times l + \frac{\pi (\frac{l}{2} )^{2} }{2}$

Where $w = 15 \ ft$ and $l = 10 \ ft$ . Replacing these values, we have

$A= 15 \times 10 + \frac{3.14 (\frac{10}{2} )^{2} }{2}\\ A=150 + \frac{3.14 \times 25}{2}=150+39.25 \\ A \approx 189.25 \ ft^{2}$

Therefore, Mjhs needs 189.25 square feet of blue paint, approximately.

What is the value of x? x = ?

meriva

 Sum of both the angle will 180 because of linear pair

now, 10x - 20 + 6x + 8 =. 180 

 16x - 12 = 180

16x = 192 

x= 192/16

x = 12

1st angle = 100

2nd is = 80

Hope it helps and your day will full of happiness

Find the distance and midpoint for the following coordinates. P(7.6 , 10.1) and Q(4.6 , 3.1)

KATRIN_1 [288]

Solving for the midpoint:

x - coordinate: (7.6 + 4.6)/2 = 6.1
y - coordinate: (10.1 + 3.1)/2 = 6.6

Midpoint: (6.1 , 6.6)

Solving for the distance:

Distance formula: sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

D = sqrt( (7.6 - 4.6)^2 + (10.1 - 3.1)^2 )
D = sqrt( 3^2 + 7^2)
D = sqrt(58)
D = 7.62 units

Distance = 7.62 units
