Answer:
234 inches
Step-by-step explanation:
Area= base x height
Height= 18 inches
Base= 13 inches
The height of a parallelogram must be perpendicular to its base, the base of this parallelogram can only be 13 inches and the height is 18 inches. Since the side lengths are not straight lines the height must be found using this method.
The height of a triangle, parallelogram and trapezoid must have a height that is perpendicular to its base. Whereas it can be found by extending the length of the base or straightening the side length that is to be the height creating a right angle.
Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one. Adding 0.6r to both sides makes the coeff. of r a positive one: 0.6r greater than or equal to 2.9+1.3.
0.6r then is equal to or greater than 4.2. Divide both sides by 0.6 to isolate r:
r greater than or equal to 7.
Let r be represented by the horizontal number line. Darken r = 7 and also darken the r axis to the right of r=7.

Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
Answer:
56π
Step-by-step explanation:
1. Approach
To find the radius of a circle, use the formula;
π
To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.
It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.
2. Area of the larger circle
π
Substitute in known value (use 3.14 for π)
A = 254.47
3. Area of the smaller circle
π
Substitute in known value (use 3.14 for π)
A = 78.54
4. Area of the shaded region
Subtract the area of the smaller circle from the area of the larger circle;
254.47 - 78.54 = 175.93
~ 56π
Answer:
She will have stretched her neck 1 time, she will have stretched her legs 2 times, and she will have stretched her arms 4 times.
Step-by-step explanation:
This is because 1/2 can only go into 2/3 once, 1/3 can go into 2/3 twice, and 1/6 can go into 2/3 four times.
