Answer:
54
Step-by-step explanation:
15/5 = 3 columns in each row are shaded. There are 18 rows, so 3×18 = 54 cells are shaded.
Answer:
TV = 66
Step-by-step explanation:
Since M is the midpoint, that means the two subsegments are equal so
7x - 2 = 4x + 13
7x - 4x - 2 = 13
7x - 4x = 13 + 2
3x = 15
x = 5
then
TM = 7x - 2 = 7*5 -2 = 35 - 2 = 33
TV = 2 * TM = 2 * 33 = 66
Answer:
Completing the square
Step-by-step explanation:
The next step would be to factor into a perfect square
Answer:
155.7
Step-by-step explanation:
Use what you know.
Segment AC is 130 ft
Segment CD is 70ft
If you use the Pythagorean Theorem, in this case being = +
To find segment CE, you would do r-70
So, = +
= 16,900 + -140r + 4900
Add the -140r to the left side and then get rid of the two . Then Add 16,900 and 4900 together
You'll end up with 140r = 21,800
Divide 140 on each side.
Your final answer will be 155.7 (rounded to the nearest tenth)
