A square patio has an area of 200 square feet. How long is each side of the patio to the nearest tenth?

1 answer:

6 0

If patio is square it means that area of if is $A=a^2$ where a is one side
Now we can substitute A=200 and solve eq
$a^2=200$
a= $\sqrt{200}$
a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1

Answer:

the population this year is 15 I think

Step-by-step explanation:

the population this year is 15 I think because 60 = 100% so if you divide 60 into two you will get 30 / 50%. then divide 30 again which would be 15 and that's 25 percent. only if you know what 60 divides by 2 and then 30 divided by 2.

Answer:

x + 37 = 90

Step-by-step explanation:

Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.
