Answer:

The answer is 11/14 ft^2 or pi/4 ft^2

Step-by-step explanation:

The area of the sector bounded by that angle measure will be the area of the circle divided by 4

Area of the circle is;

pi * r^2

so the area here is;

22/7 * 1 * 1 = 22/7

divide this by 4

= 22/28 = 11/14 ft^2

Find the distance between the points 3,7 and 15, 12 on the coordinate plane?
lana [24]
\text{Distance } = \sqrt{ (x_2 -x_1)^2 + (y_2 - y_1)^2}

\sqrt{ \left( 15 -  3\right)^2 +  \left( 12 -  7\right)^2}\\\\\sqrt{\left( 12\right)^2  + \left( 5\right)^2}\\\\\sqrt{    144  +   25 }\\\\\\ \sqrt{   169 } = \boxed{\bf{ 13}}

Instructions: Simplify the algebraic expression.<br><br> −12(32x−10y)
allochka39001 [22]

Answer:

-384x - 120y

Step-by-step explanation:

General Concepts and Formulas:

Brackets

Parentheses

Exponents

Multiplication

Division
A
ddition
S
ubtraction

Steps:

1) Distribute

-12(32x-10y)

We must distribute the expression above by multiplying -12 by the coefficients and then adding the variables.

So first, multiple -12 by 32 and add the variable 'x' when getting the product:

-12(-384x - 10y)

Now that we have one part, let's solve the other part.

We now must multiple -12 by -10, which gets us 120, now we must plug in:

(-384x - 120y)

(Remove parenthesis)

⇒  -384x - 120y

You are a landlord, and your tenant complains that you are in violation of the ADA because your wheelchair ramp is too steep. An
Savatey [412]

Answer:

  Not justified

Step-by-step explanation:

ADA requirements are for a slope of 1 in 12 or less, an 8.3% grade, or an angle of 4.8° (actually, 4.764° when rounded to 3 decimal places). The ramp angle found by the assessor is compliant.

  The tenant complaint does not seem justified.

Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inc
wlad13 [49]

Answer:

A cross-section parallel to the base is a rectangle measuring 15 inches by 8 inches.

A cross-section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

A cross-section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Step-by-step explanation:

the cross sections that are parallel and perpendicular will have the same measurements as the non-intersected sides. the last one will be a diagonal so the intersected edge is 6 and it creates a right triangle so it must be larger than 15 inches.
