Triangles have 3 vertices. The total is 21 vertices. 21 / 3 = 7. He drew 7 triangles.
Answer:
A
Step-by-step explanation:
10 and 8 are equal
11 and 15 are equal
due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees
180-42=138 degrees
and this means that angle 8 will also be 138 because of what we established earlier
It's 21.125 hope this works good luck ;)
This is a "rate of pay" problem. The amount earned is equal to the (rate of pay) times the (number of hours worked).
Let the income be represented by "i". Then the formula is i = ($10.91/hour)*w, where w is the number of hours worked and has the unit of measurement "hours."
Multiply 400 times 0.70 and that’s how you get the % (in this case 280)
