Answer:
3
Step-by-step explanation:
You can use your number sense to realize that 8/9 is between 3/4 and 1, so Tyrone can only get 3 whole pieces from his string.
__
If you like, you can do the division ...
(8/9)/(1/4) = (8/9)(4/1) = 32/9 = 3 5/9 . . . . . 3 whole pieces
Or, you can compare decimal values.
1 piece = 0.25 ft
2 pieces = 0.50 ft
3 pieces = 0.75 ft
4 pieces = 1.00 ft
String length = 0.888.... ft (more than 3; less than 4 pieces)
<span>Well 68/80 as a percent is 85 % .I got that by dividing 68 by 80 and them multiplying by 100. 100-85= 15. So therefore the dress decreased in price by 15%. </span>
In every number, set every digit to zero that is not 8. Then look at the question again.
"Which of these lengths has 1/10 the value of 8.0?"
- A. 800
- B. 0.08
- C. 80
- D. 0.80
We hope the answer D is obvious to you.
... 0.80 = (1/10)×8.0
___
The appropriate choice is ...
... D. 209.86
Answer:
its C
Step-by-step explanation:
Answer:
8 π .
Step-by-step explanation:
radius increases at a constant rate of 1 in/sec.
dr / dt = 1
where r is radius .
radius after 4 sec
r = 1 x 4 = 4 in
area A = π r²
differentiating both sides
dA / dt = 2 π r dr / dt
Putting dr / dt = 1 , r = 4 in
dA / dt = 2 π x 4 x 1
= 8 π sq in per sec.
Area increases at the rate of 8 π per sec.
