The correct first step in finding the area of a base of a cylinder is to find the length of radius of the circular base.
The unit rate would be number of miles per hour ( 1 hour).
Divide the total number of miles by the total number of hours:
100 miles / 4 hours = 25 miles per hour.
The unit rate is 25 miles.
Answer:
1/3
Step-by-step explanation:
The two points are (2, -1) and (-1, -2).
Slope is y change over x change.
So... -2-(-1) over -1-2 which is -2+1 over -3
Slope is -1/-3
The answer is 1/3.
Hope this helps :D

Answer:
130cm²
Step-by-step explanation
The amount of red appear needed by Marcus to cover his box = Surface Area of the cube - Area of the circle.
Surface area of cube = 6s² (where s is the side length of the cube. s² therefore is S.A of 1 face of the cube)
Given that s = 5cm,
S.A of cube = 6s² = 6*5² = 150cm²
Area of circle = πr²;
Given that π = 3.14, and r = ½ of diameter of circle (i.e. ½ of side length of cube)
Area of circle = 3.14*(½*5)² = 3.14*(2.5)² = 3.14*6.25 =19.625
Amount of red paper needed = S.A of the cube - Area of the circle = 150cm² - 19.625cm² = 130.375cm² = 130cm²
Answer:
a>-1/3
Step-by-step explanation:
-7a-2a<3
-9a<3
-a<3/9
a>-3/9
a>-1/3
You switch the sign because your dividing by a negative.
