Answer:
a =12*sqrt(2)
Step-by-step explanation:
3. The Pythagorean theorem states
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +21^2 = 27^2
a^2 +441 =729
Subtract 441 from each side
a^2 +441-441 = 729 -441
a^2 =288
Take the square root of each side
sqrt(a^2) = sqrt(288)
sqrt(xy) = sqrt(x)sqrt(y)
a = sqrt(144)sqrt(2)
a =12*sqrt(2)
Answer:
9.1
Step-by-step explanation:
We'd divide.
This is because:
Gallons are much more than cups. If we cant to convert cups to gallons, we divide to get a smaller unit.
Example: There are 32 cups on the table. How many gallons are there?
32/amount of cups per gallon
32/16 = 2
2 gallons,
Catherine could take the original price of $144.97 and multiply it by .09 (9%). This would equal a sales tax of $13.073 which could be rounded to $13.01. Then add the original price of $144.97 to the tax of $13.01 to get a total of $157.98.
Answer:
r ≈ 2.07
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r= C/2π = 13/2π ≈ 2.06901
