Answer:
352 cm/s
Step-by-step explanation:
circ = 44pi
speed = distance * time
distance = circ * 4 = 176pi
speed = 176pi/0.5
Complement angles, sum is equal 90
Give one angle = 70 to find other: 90 - 70 = 20
Answer
Complement of angle with the measure of 70 degrees is 20 degrees
Answer: x intercept is -3
y intercept is -9
Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept
6x+2(0)=-18
divide both sides by 6, and get -3 as an x intercept
2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.
Answer:
Step-by-step explanation:
First, we expand the equation using the distributive rule:
Hence, 
Simplify: 
Add like terms:
Subtract 13 from both sides: 
Divide both sides by -8:
