Step-by-step explanation:
I don't know the area of the glass front of your largest building.
but just think :
1 gallon of fluid costs $12
1 gallon cleans 5000 ft²
so, now, find the area (ft²) of that glass front and see what number you have to multiply 5000 with to get the area of the glass front.
then, you have to multiply $12 with that same number, and you get the price.
let's say the building's glass front has 10000 ft².
what do I have to multiply with 5000 to get 10000 ?
this is the same question as how often fits 5000 into 10000 ? which is 10000 / 5000 = 2
and 12×2 = $24 as total cost to clean it.
our the building's glad front has 2500 ft².
what do I have to multiply with 5000 to get 2500 ?
this is the same question as how often fits 5000 into 2500 ? which is 2500 / 5000 = 1/2
and 12 × 1/2 = $6 as total cost to clean it.
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
Hello There!
The length of the hypotenuse is 10.
We know what 2 sides are 6 and 8.
To find the third side we use the formula a^2 + b^2 = c^2
So we multiply 6 by 6 which equals 36 and then multiply 8 by 8 which equals 64.
Next we add 64 and 36 together and we get 100.
Next, we square root 100 and get 10.
10 is the length of the hypotenuse.
