Answer:
measure of each base angle = 80 each angle
measure of vertex angle = 20
Step-by-step explanation:
x=base angle
2x+ x/4= 180
Multiply everything by 4 to eliminate the fraction
8x+x = 720
9x=720
x=80
80/4=12
Answer:
$3,150
Step-by-step explanation:
To find the sale price, multiply the original price ($3,500) by 0.90. This 0.90 comes from subtracting 10% from 100% and converting the result to the decimal fraction 0.90.
0.90($3,500) = $3,150
Got your answer.
I drew it out on a digital drawing software I have.
Answer:
70
Step-by-step explanation:
First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.
Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.
