Answer:
-17x - 27
Step-by-step explanation:
Distributive property is the multiplication of the number outside the parenthesis and the ones inside.
-5(x + 4) + -3x + -9x + -7
-5x - 20 + -3x + -9x + -7
Combine like terms:
-5x - 20 + -3x + -9x + -7
-5x +-3x
-8x + -9x
-17x
-17x - 20 + -7
-20 + -7
-27
The answer is -17x - 27
Hope this helped.
Answer:
area of sector dfe=(360-110)/360×πr²=250/360×22/7×4²=34.9=35ft²
Answer:
A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.
(this may be more of an architect's job, as they are the ones that design the houses)
or
An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
First, get the difference between the price level changes.

Then, divide it by the initial price level, which is 109.

Multiply by 100 to get its percent.

Thefore, the inflation rate during the year is 3.67 percent.
Answer:
20 years
Step-by-step explanation:
9000/ 100= 900 = 10%
900/2= 450
450 x 2= 900
900 x 10= 9000
Now we multiply 10 by 2 because we doubled the value of our 450 into a 900 and now we get 20.
