Answer: 1.16 x 10 ^-1
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
77 cm²
Step-by-step explanation:
We know that
Area of trapezium = ½ (a + b) × h
Area = ½ × (10 + 12) × 7
Area = ½ × 22 × 7
Area = 11 × 7
Area = 77 cm²

Answer:
It didn't saying anything about rounding but the the dimensions in there exact form are:
and
.
Now if they said to round to the nearest hundredths the dimensions in this rounded form would be:
L=5.39 cm and W=5.19 cm
(Check your question again and see if you meant what you have)
Step-by-step explanation:
L is 5 less than twice W
L = 2W-5
Area of rectangle=L*W
Area is 28 means L*W=28.
I'm going to insert L=2W-5 into L*W=28 giving me
(2W-5)*W=28
Distribute
2W^2-5W=28
Subtract 28 on both sides
2W^2-5W-28=0
a=2
b=-5
c=-28
We are going to use the quadratic formula.
Plug in...
W needs to be positive so
And
Does L*W=28?
Let's check.
In the last step, I was able to do a quick multiplication because I was multiplying conjugates. (a+b)(a-b)=a^2-b^2.
