i can't understand the question but if you put a link I can figure it out
The new copier can create 2000 copies in 20 minutes.
Step-by-step explanation:
Given,
It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion
Product of mean = Product of extreme
Dividing both sides by 60
As the new copier is working with old copier, therefore,
Copies made by new printer = 2000 - 500 = 1500
New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion
Dividing both sides by 1500;
The new copier can create 2000 copies in 20 minutes.

Answer:
88 25/27
Step-by-step explanation:
(13 – 6)^2 (5 + 2)^2÷(5 – 2)^3
PEMDAS
Parentheses first
(7)^2 (7)^2÷(3)^3
Then exponents
49*49 ÷27
Then multiply and divide from left to right
2401÷27
2401/27
88 25/27
88.92592593
Answer:
V = 166.4
Step-by-step explanation:
The ratio of lengths of similar figures is the scale factor.
The ratio of the surface areas of similar figures is the square of the scale factor.
The ratio of the volumes of similar figures is the cube of the scale factor.
We don't know the scale factor of the figures, but we know the ratio of the surface areas is 200/135.
That is the square of the scale factor.
Let k = scale factor.
k² = 200/135 = 40/27
The ratio of the volumes is
k³ = [√(k²)]³
k³ = [√(40/27)]³ = 1.80320
V = 300/1.80320
V = 166.4
