Answer:
V=pi r² h/3
Step-by-step explanation:
V=volume
R=radius
H=height
Answer:
j
Step-by-step explanation:
We can subtract 3 in the x-coordinate and 7 in the y-coordinate for both points.
(3-3,7-7) = (0,0)
(-5-3,-3-7) = <-8,-10>
Hope this helps!
Answer:
445
Step-by-step explanation:
Answer: -4 = <em>w OR w = -4</em>
Step-by-step explanation: For this given equation you will have to solve for the variable w. In order to do this you must isolate the variable <em>w.</em>
Step 1: Use the distributive property: -79=7w+3(4w-1) ( 3 x 4w = 12w and 3 x -1 = -3.
Step 2: Add like terms and whole numbers: -79=7w+12w-3 ( 7w + 12w = 19w
Step 3: Use the Addition Property of Equality:3 + -79=19w-3+3 ( 3 + -79 = -76 and -3 + 3 =0
Step 4: Use the division Property of Equality: -76=19w -76 divided by 19 is -4 and 19w divided by 19 is w
Step 5: The answer: -4=w
Answer:
3 miles
Step-by-step explanation:
A trapezoid has an area of 18 square miles. The bases are 5 miles and 7 miles. Using these measurements, the height of this trapezoid is how many miles
Area of a trapezoid = 1/2 (a + b)h
The formula for the height of a trapezoid =
h = 2(A/a + b)
A = 18 square miles
a = 5 miles
b = 7 miles
h = 2(18/5 + 7)
h = 2( 18/12)
h = 2 ( 9/6)
h = 3 miles
