Answer:

Step-by-step explanation:

arc between cars = 360°/25 = 14.4°

θ = 14.4° × π/180 ≅ 0.2512 radian

r = 150/2 = 75 ft

s = rθ = 75×0.2512 = 18.84 ft

area of circle = πr² = 75²π ≅ 17,662.5 ft²

area of sector = 17,662.5/25 = 706.5 ft²

Is this answer right?? If not what’s the real answer? I’m trying to practice for my STAAR.

Area of rectangle

21m^2

Area of one triangle

divide length of 7 by 2 (3.5)

gives you length b (unknown side that is not hypotenuse)

then multiply by width of triangle (4)

3.5 * 4 = 14

and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.

add the area of the rectangle

14+21= 35

35m^2

How do you solve for x? 6x+7=6

skelet666 [1.2K]

6x+7=6

Subtract both sides by 7
6x+7-7=6-7

6x=-1

Divide both sides by 6 to isolate x
6x/6=-1/6

x=-1/6

Volume of a Sphere Formula: $\displaystyle V = \frac{4}{3} \pi r^3$

r is radius

Step-by-step explanation:

Step 1: Define

Identify variables

r = 8 ft

Step 2: Find Volume

Substitute in variables [Volume of a Sphere Formula]: $\displaystyle V = \frac{4}{3} \pi (8 \ ft)^3$
Evaluate exponents: $\displaystyle V = \frac{4}{3} \pi (512\ ft^3)$
Multiply: $\displaystyle V = \frac{2048}{3} \pi \ ft^3$
Estimate: $\displaystyle V = 2144.66 \ ft^3$

What is the value of?

katrin [286]

Answer:

70 degrees

Step-by-step explanation:

Since the angles of a triangle have to add up to 180 degrees, you know that the third angle of the triangle on the left would be 180 - 60 - 65 = 55 degrees. Then, since the angles on a straight line have to add up to 180 degrees you could find one of the two missing angles of the second triangle by doing

180 - 55 - 50 = 75.

Then, you have 2 out of the 3 angles of the triangle on the right and you can find the third, the ?, by doing 180 - 75 - 35 = 70 degrees
