Answer:
a = 3
b = 2
Step-by-step explanation:
The ratio of the corresponding sides of two similar triangles are always equal. Therefore,
9/a = 18/6 = 6/b
✔️Let's solve for a:
9/a = 18/6
9/a = 3
Cross multiply
a*3 = 9
Divide both sides by 3
a = 9/3
a = 3
✔️Let's find b:
18/6 = 6/b
3 = 6/b
3*b = 6
b = 6/3
b = 2
Answer:
85 1/3 in^3
Step-by-step explanation:
volume=base area s hight
63 <= 7y
To solve for y just divide both sides by 7:
Y <= 63/7
Y <= 9
Because 63 is less than , you need to reverse the inequality sign.
The answer becomes y >=9
Now when you replace y with a number from 9 or higher the inequality will be true.
Answer:
{7, 8, 9, 10}
Step-by-step explanation:
Having worked 4 hours babysitting, Zoé has already earned 4×$7 = $28, so only needs to earn $130 -28 = $102 more.
At $15 per hour, it takes her $102/$15 = 6.8 hours to earn that amount. In order to keep her total hours to a maximum of 14, Zoé cannot work any table-clearing hours more than 14 -4 = 10. The possible solutions for Zoé's hours doing table clearing are ...
{7, 8, 9, 10} . . . . hours
_____
We have assumed Zoé must work whole numbers of hours.
