Answer:
-14
Step-by-step explanation:
Always use the order of operations.
First, solve within the paranthesis,
Second, solve the exponents,
Third, do the multiplication and division in whichever order it is in.
Fourth, do the addition and subtraction in whichever order it is in.
(5 + 4 - 2) × (-2) = 7 × -2 = -14
When multiplying to cancel out units, a unit is canceled when in one term it is on top and in another term it is on the bottom.
So in the first blank we are needing to cancel out miles (mi) so that it does not end up in the final answer. Since it is on the bottom in the second term, we need it to be on the top in the first blank - therefore the first blank is:
Then when we go to find out what all of what we multiplied equals, we must go back and cancel out units that are both on the top and the bottom, as they are not to be included in the final answer.
So as we can see, with in the first blank, miles (mi) are cancelled, then in the 2nd and 3rd terms yards (yd) is on the top and on the bottom, so that is cancelled out, and then we are only left with feet (ft) on the top. Therefore, feet will be the only unit that is left in the equation and that is the final blank: ft.
Answer:
Triangle = 5
Circle = 25
Square = 100
Pentagon = 1600
Rectangle = 155
Step-by-step explanation:
6 x triangle = 3 x 10
Solve for 3 x 10
6 x triangle = 30
Divide both sides by 6
Triangle = 5
•••••••••••••••••••••••••••••••
Triangle x 20 = Circle x 4
Substitute triangle for 5
5 x 20 = Circle x 4
Solve for 5 x 20
100 = Circle x 4
Circle = 100 divided by 4
Circle = 25
•••••••••••••••••••••••••••••••
Circle + triangle = square minus 70
Substitute Circle and Triangle for their values
25 + 5 = square - 70
Solve for 25 + 5
30 = square - 70
Add 70 to both sides
square = 100
•••••••••••••••••••••••••••••••
Square x 8 = 1/2 of pentagon
Substitute square for 100
100 x 8 = 1/2 of pentagon
Solve for 100 x 8
800 = 1/2 of pentagon
Pentagon = 1600
•••••••••••••••••••••••••••••••
Pentagon divided by square = rectangle + 5
Substitute pentagon and square for their values
1600 divided by 100 = rectangle + 5
Solve for 1600 divided by 100
160 = rectangle + 5
Subtract 5 from both sides
Rectangle = 155
••••••••••••••••••••••••••••••••••
Rectangle x rectangle = ?
Rectangle = 155
Rectangle x rectangle = 24025

Answer:
Parallel 6 10 13 17 and perpendicular 2 8 14 16 18 I think
Step-by-step explanation:
The volume of the <span>cylinder </span>= π r² h
r ⇒⇒⇒ radius
h ⇒⇒⇒ height
r = 5 ft and h = 3 ft
volume = π * 5² * 3 = 235.62 ft³
rounding to the nearest ft² = 236 ft³
The fourth choice is the correct answer
