Answer:
12
Step-by-step explanation:
Answer:
x = 19.5 or 19 1/2
Step-by-step explanation:
cos 41 = 14.7/x
x = 19.5
Answer:
A = 5x + 12 (See explanation!)
Step-by-step explanation:
So, this "polygon" is really just two rectangles combined! With that in mind, remember that the area of a rectangle is base*height. Now, apply that to the problem. We know that the total length of the bottom base is 7, and 5 is the length of the second rectangle's base, so the 1st rectangle's base must be 7 - 5 = 2. The area of the 1st rectangle is then 6*2 = 12. The second rectangle's area is 5*x. So, if the area of the polygon is the sum of the two rectangles' areas, the expression you could use is:
5*x + 6* 2 = A
Simplify/Rewrite:
A = 5x + 12
(A is area, x is the unknown length in the diagram)
Hope this helps!
Answer:
-11(-12)=132
Step-by-step explanation:
First divide 132 by negative 11 and get -12.
Then you connect -12 into the equation by using paraenthisies so its not a mess.
Last check your answer. -11 times -12 is equal to positive 132.
The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
