Answer and Step-by-step explanation:
The statements are not given, but I'll try to analyze the problem to my possible best, so that anyone can understand the problem well.
Matt is owing his sister $300. If he mows lawns after school and on weekends, it means he works 7 days a week.
Since he charges $30 per lawn and gives his friend $10 to help. It means, he earns $20 per lawn. Therefore, every week, he makes $20 x 7 = $140.
If Matt pays his sister half of what he earns per lawn, it means after a week, he will pay her $140 ÷2 = $70.
This means he has to pay $70 for 4 weeks, then pay $10 for 2 days to clear up his debt. This is because, $70 x 4 = $280 and $10 x 2 = $20. Thus, $280 + $20 = $300.
Answer:
he isn't
Step-by-step explanation:
The wood has dimensions of 18 x 12
If He wants the tray to have a height of 2, subtract 2 x 2 from both the length and the width
18 - 4 = 14
12 - 4 = 8
the highest possible dimensions of the tray can be 14 x 8
10 1/2 x 10 1/2 is greater than 14 x 8. so he is not correct
Answer:
k = 1/2
y = -108
Step-by-step explanation:
y varies jointly as x and the cube of z
y =kxz^3
We know y=16 when x=4 and z=2 so we can determine k
16 = k (4) 2^3
16 = k*4*8
16 = 32k
Divide each side by 32
16/32 = 32k/32
1/2 = k
y = 1/2 xz^3
Now y=? when x=-8 and z=-3
y = 1/2 * 8 (-3)^3
y = (1/2) *8 (-27)
y =4 (-27)
y = -108
