The diameter of a circle is 20 ft. Find its area in terms of T.
Ksivusya [100]

Answer:

314.2ft^2

Step-by-step explanation:

Given data

Diameter= 20ft

Radius r= 20/2= 10ft

The expression for the area is

A= πr^2

A= 3.142*10^2

A= 3.142*100

A= 314.2ft^2

Hence the area is 314.2ft^2

Stolb23 [73]

Answer:

C

15 + x

Step by step explanation

For Company X, the initial cost is 30 cents  plus 5 cents per minute, so the expression would be 30 + 5x (x would represent minutes.

For Company Y, the initial cost is 15 cents  plus 4 cents per minute, so the expression would be 15 + 4x (x would represent minutes.)

Then subtract the expression of Y from the expression of X to show the difference in value between Y and X.

So, 30 + 5x - (15 +4x)

Distribute the subtraction sign.

30 + 5x - 15 - 4x

Solve across.

15 + x

A parallelogram has one angle that measures 50°. What are the measures of the other three angles in the parallelogram?
Sedaia [141]

Answer:

130°, 50°, 130°

Step-by-step explanation:

Two opposite angles of parallelogram are always congruent, so the measure of angle opposite to the angle 50° is 50° too.

Two consecutive angles of parallelogram always are supplementary (add up to 180°), so the angle consecutive to the angle 50° has the measure of

180° - 50° = 130°

Angle opposit to 130° angle has the measure of 130° too.
