Answer:

53

Step-by-step explanation:

86 = 2x - 20

+20       +20

106 = 2x

2       2

53 = x

Answer:

x = 53

Step-by-step explanation:

Those 2 are alternate interior angles. So that means they're the same

2x - 20 = 86     <-- Add 20 to the right side

2x = 106     <-- Divide by 2

x = 53

Radius of Mercury = 4880÷ 2 = 2440 km

c) Mass of Jupiter = 1.898 * 10²⁷ = 18.98 * 10²⁶

Mass of Saturn = 5.68 * 10²⁶

Difference  = 18.98 * 10²⁶ - 5.68*10²⁶

The maximum height is 36.75feet at 2.5 seconds. Using the quadratic equation, you can calculate the x coordinate of the vertex with -b/2a. In this case, the x coordinate of the vertex is the time the swipe card reaches its max height , and it is 2.5. To calculate the maximum height, substitute 2.5 into each variable of t in the original equation, and the solution is 36.75.

Answer:

A

Step-by-step explanation:

The area of the large triangle is 36*24/2

minus the small triangle which is 21*14/2

so 432-147 = 285

This is very hard to explain in text and not on paper, but I will try to explain it the best I can.

So first get the length of the bottom of the triangle, so that would be 36in. Minus 21in. Which will give us the length of the bottom of the shaded region.

36-21= 15 in.

This next step isn’t necessary, but it makes solving for the area so much easier. Make the shaded region into two different shapes. So in this case, a square and then a right triangle.

So take the height on both sides on the shaded region, which would be..

24 - 14 = 10in.

Now, multiply the length by the height to solve for the area of the square and triangle.

Triangle area: 15(10)= 150 sq. in.

Square area: 15(14)= 210

Now add them together and then you get your answer.

210 + 150 = 360 sq. in.

The area of the shaded region is 360 sq. in.

A basketball court is a rectangle that is 94 feet long. The area is 4700 square feet. What is the width of a basketball court?
A. 25 feet
B. 41 feet
C. 50 feet
D. 100 feet​

Answers

Answer: C: 50 feet

Step-by-step explanation: The area of the basketball is 4700 square feet. We know that one side of the court is 94 feet long. To find the area for a rectangle, the formula would be Area=base times height. The "height" of this rectangle is 94 feet long. Now we need to find the base.

If you divide 4700 by 94, you will end up with 50 feet. To check, you multiply 50 by 94 and should end up with 4700. 50 feet is your base length.
