Answer:

It is so easy u should get this right.

First draw a circle and there is an arc that is like forming a triangle inside a circle and then ab angle is 100 degree and outside is the center of the circle. And since u try to find how much is outside it most likely means that 100-60=40

I need answers for 1 and 2
Snowcat [4.5K]

1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5

Below are the rates of travel of 4 shipping trucks. Which truck drove the fastest rate? Truck A: 300 miles in 4 hours Truck B: 2
Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

v_A=\dfrac{300}{4}\\\\v_A=75\ mph

Speed of Truck B,

v_B=\dfrac{240}{3}\\\\v_B=80\ mph

Speed of Truck C,

v_C=\dfrac{325}{5}\\\\v_C=65\ mph

Speed of Truck D,

v_D=\dfrac{170}{2}\\\\v_D=85\ mph

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.

What Is the area of the shaded part???​
Aloiza [94]

Answer: The area of the shaded region is 27.74 centimeters squared

Step-by-step explanation: The diagram shows a two-in-one figure, a circle inscribed in a rectangle. The shaded region is the part of the rectangle not covered by the circle, hence we would have to subtract the area of the circle from that of the rectangle.

Area of Rectangle = L x W

Area of rectangle = 8 x 7

Area of rectangle = 56

Also,

Area of circle = Pi x r^2

Area of circle = 3.14 x 3^2

Area of circle = 3.14 x 9

Area of circle = 28.26

Area of shaded region is given as area of rectangle minus area of circle

Therefore, shaded region = 56 - 28.26

Area of shaded region = 27.74 centimeters squared
