she has $13.80 every hour because 842 divided by 40 plus 12 equals 61 so then and you cant round anymore.
It also means that a rhombus is formed from 2 identical equilateral triangles ( 2 identical 30 - 60 - 90 triangles forms one equilateral ) and a side of that triangle measures : 30 feet.
Answer:
The perimeter of the garden : 4 * 30 = 120 feet
Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
Answer:
If the sphere has a radius of 4, you can use the equation: V=4/3(pi)(r)^3
Step-by-step explanation:
V=4/3(pi)(r)^3
V=4/3(pi)(4)^3
