3.14
Step-by-step explanation:
Answer:
0.5 < x < 16.5
Step-by-step explanation:
The third side of the triangle must be longer than the difference of the other two sides:
x > (8.5 -8.0)
x > 0.5
And it must be shorter than their sum:
x < (8.5 +8.0)
x < 16.5
The third side must be in the range ...
0.5 < x < 16.5
_____
These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches
Answer:
567
Step-by-step explanation:
It will become:
y = 7(3)^4
y = 7 * 81
y = 576
Answer:
<u>5.56 hours</u>
Step-by-step explanation:
Margo read 42 pages in 2.5 hours.
Pete read six fewer pages in the same amount of time.
So, The number of pages that Pete reads = 42 - 6 = 36 pages
So, Pete read 36 pages in 2.5 hours.
let the time needed to read 80 pages x
∴ 36 pages ⇒ 2.5 hours
80 pages ⇒ x hours
∴
Using cross multiplication:
∴
So, The time taken to read 80 pages
= <u>5.56 hours = 5 hours and 33.33 minutes</u>
