Answer:

Option 1. 9.42×3 in² is the correct option.

Step-by-step explanation:

As it has been given in the question that Kyra has arranged the circle sectors in the shape of a parallelogram.

Side of a parallelogram = 9.42 in. and height of this parallelogram is 3 in.

Now we know the formula of the area of a parallelogram = length × height

Area = 9.42 × 3 in².

So the area of this arrangement of the sectors = 9.42×3 in².

2 r π / 2 = 9.42 in
r π = 9.42 in
r = 9.42 : 3.14 = 3 in
Area of the circle:
A = r² π = 3² π = 9 π in² = 28.26 in²

Write a linear equation that passes through the points(2,-2) and (0,1)
Yakvenalex [24]

Answer:

Slope intercept: y = -3/2x + 1

Point slope: y + 2 = -3/2 * (x - 2) [Forgot to add the work for this, I will add it if you need it, feel free to ask.]

Step-by-step explanation:

m = (change in y)/change in x)

But also

m = y_2 - y_1/x_2 - x_1


So lets substitute

m = 1 - (-2)/0 - (2)

Lets find the slope

m = 3/0 - (2)

m = 3/-2

m = -3/2 (Moved the negative)

Now we find the value of b using the equation of a line.

y = mx + b

y = (-3/2) * x + b

y = (-3/2) * (2) + b

-2 = (-3/2) * (2) + b

Now we find the value of b

Lets rewrite

-3/2 * 2 + b = -2

Cancel the CF of 2

-3 + b = -2

Move the terms without b to the right

b = -2 + 3

b = 1

Now we substitute our values of the slope and y-int into y = mx + b to find the equation.

y = -3/2x + 1

A number is decreased by 40% to 525. what is the original amount?​
zhenek [66]

Answer:

875

Step-by-step explanation:

lets assume the original amount X

the new amount = X - ( X × 40% )

525 = (60 × X) ÷ 100

X = ( 525 × 100 ) ÷ 60

<u>X = 875</u>

That would be the freedom of speech and the freedom of the press.

Both of these are without a doubt a center of political to the political system existing in the United States. They state that both the freedom of speech and the press is to be expressed freely.

People are free to express their opinions and through the press they gain the necessary information to make educated decisions about the burning political questions.

Hope this helps!
