Hey there! I'm happy to help!
Since this mural is a square, all the sides are the same. This means that you square on of the sides to get the area (multiply it by itself). If we have the area and want to find a side, we just go backwards and use something called the square root!
If we plug this into our calculators...
√138≈11.74734
We see that is closest to B. 12 ft.
You could also figure this out without a calculator. 138 is very close to 144, which is 12². All the other answer options are way too big.
Have a wonderful day! :D
Answer:
7 - x meters
Step-by-step explanation:
This is a difference of squares. The formula for difference of squares is
a^2-b^2 = (a-b)(a+b)
So plug the numbers we know into this formula.
Area = lw
49 - x^2 = (a-b)(7+x)
49 - x^2 = (7-x)(7+x)
<u>The length is 7 - x meters.</u>
Answer:
the original number is 7
Step-by-step explanation:
7•4 = 28
28+12=40
Answer:
d. $10,234.80
Step-by-step explanation:
we are given
The equipment will cost $26,000
so, Amount is $26000
A=26000
should be invested today at 12%
r=12%=0.12
It is compounded semiannually
so, n=2
t=8
now, we can use formula

now, we can plug values

now, we can solve for P

Answer: Unlikely
Step-by-step explanation:
Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking=
We know that the probability of any event lies between 0 and 1.
- If probability of occurring event is 0 then the event is impossible.
- If probability of occurring any event is 1 then the event certain.
- If probability of occurring any event lies between 0.5 and 1 then the event is said to be likely.
- If probability of occurring any event lies between 0 and 0.5 then the event is said to be unlikely.
Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.
