Answer:
the answer is 3/16.
Step-by-step explanation:
First, let's take a look at the expression itself.
We have to multiply 3/8 and 1/2, which gives us the expression of
3/8*1/2
then, we multiply the numerator by the numerator and get 3, then we multiply the denominator by the other denominator which gets us 16. We put the two parts together and get
3/16
which is not simplifiable. So 3/16 is the simplest answer we can get.
L = 3 + 2w
Find the width
Area = 54
l × w = 54
(3 + 2w) × w = 54
3w + 2w^2 = 54
2w^2 + 3w - 54 = 0
(2w - 9)(w + 6) = 0
w = 9/2 or w = -6 (width shouldn't be negative)
w = 9/2
w = 4.5 m
Find the length
l = 3 + 2w
l = 3 + 2(4.5)
l = 3 + 9
l = 12 m
The width is 4.5 m, the length is 12 m
Answer:
8.48%
Step-by-step explanation:
Bill's weight decreases from 64.8 kg to 59.3 kg.
We need to find the percentage decrease in Bill's weight. It can be calculated as follows :
So, the required decrease in percentage is 8.48%.
Answer:
x<7
Step-by-step explanation:
65-8x>9
-8x>9-65
-8x>-56
x<7
The solutions are 
.
Solution:
Given equation:
Add 
on both sides.
-------- (1)
(given) -------- (2)
Equate (1) and (2).
Add 
on both sides.
Add 5 on both sides.
Divide by 5 on both sides, we get
Taking square root on both sides, we get
Substitute 
in (1).
Substitute 
in (1).
Therefore the solutions are .
Option C is the correct answer.
