7/4 you would reduce by 2
Step-by-step explanation:
Let Jim earned $ x
Therefore, Debbie earned = $(x + 1600)
According to the given information:
Thus, Jim`s earning = $2800
Debbie`s earning = 2800 + 1600 = $4400
Answer: 21?
Step-by-step explanation: if the ratio is 7:5 and its now x:15 and 15 divided by 5 is three so you have to multiply 7 by three to.
Step-by-step explanation:
The volume of a pyramid or cone is:
V = ⅓ Ah
where A is the area of the base and h is the height.
The pyramid has a square base, so:
A = s²
A = (7 cm)²
A = 49 cm²
The height is 14 cm, so the volume is:
V = ⅓ (49 cm²) (14 cm)
V = 686/3 cm³
V ≈ 228.67 cm³
Answer:
vol = 148.9 cm³
Step-by-step explanation:
Vol of a cylinder = π r² h
where r = 3.4 cm
h = 4.1 cm
vol = π * 3.4² * 4.1
vol = 148.9 cm³
