Answer:
Atleast 88 miles
Step-by-step explanation:
We are given that
A moving company charges a flat rate=$85
Cost of 1 mile driven=$0.17
We have to find the distance drive by the company to earn at least $100.
Let x mile drive by company .
According to question
Subtract 85 on both sides of inequality
Divide by 0.17 on both sides
(round to nearest mile)
Hence, the company must drive atleast 88 miles to earn atleast $100.
a=alan
b=billy
c=charlie
a is 80% more than charlie means that a is 100% and billy=20%, so 20% of alan=billy
0.2a=c
b has 3/5 of c
b=3/5c
if b-150 and c+150, (c+150)=3 times (b-150)
luckily we can related c and b
b=3/5c
c+150=3(3/5c-150)
distribute
c+150=9/5c-450
add 450 both sides
c+600=9/5c
minus c both sides
600=4/5c
times 5/4 both sides
750=c
charlie has 750 stamps
billy=3/5 times c
b=3/5 times 750
b=450
allan has 80% more than billy
0.2a=b
0.2a=450
divide both sides by 0.2
a=2250
b=450
a=2250
c=750
add them
a+b+c=2250+450+750=3450 stamps
Answer:
The brace is ft ≅ 12.806 ft long
Step-by-step explanation:
The length of the diagonal of a rectangle can be found using this rule
, where
∵ The gate has shaped a rectangle
∵ Its length = 10 ft
∵ Its width = 8 ft
∴ l = 10 and w = 8
∵ The brace is the diagonal
→ By using the rule above
∴
∴ The length of the brace = ≅ 12.806 ft
∴ The brace is ≅12.806 ft long
