Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x
Answer:
$1.09
Step-by-step explanation:
16*0.09 = 1.44, 16 + 1.44 = 17.44 (Henry's total cost)
17*0.09 = 1.53, 17 + 1.53 = 18.53 (Ella's total cost)
To find the difference we subtract 18.53-17.44 = 1.09 and so the difference including tax is $1.09
Answer: 12 minutes
Step-by-step explanation:
Two rates for hoses A and B. FP is the Fish Pond.
A = 20 min/FP or (1/20)FP/min
B = 30 min/FP or (1/30)FP/min
The time in minutes, X, to fill one FP:
1FP = X*((1/20)FP/min) + X*((1/30)FP/min)
1FP = X*(1/20+1/30)FP/min
1FP = X*(2.5/30)FP/min
X = 12 minutes
Answer:
Well the answer is 857.4 meters per minute
Step-by-step explanation:
The reason is because 1.429 times 60= 85.74 That means that you walk 85.74 meters per second. Then that times 10 is 857.4 . Can I get brainliest
