Answer:
He will spend 42 dollars
Step-by-step explanation:
7 times $6
= $42
(If that's what you're asking)
If you graph this scenario, the number of gallons of gas left will be on the y-axis while the number of miles traveled will be on the x-axis.
The line will be going downwards as the miles get longer. This is because the number of gallons of gas left will decrease as Janelle drives farther.
Assuming that Janelle initially had 10 gallons of gas and 1 mile consumes 1 gallon.

Answer:
59
Step-by-step explanation:
Round 59.3506494 to the first 2 sig figs which is 59 since the number next to the decimal isnt over or 5, so it stays as 59 instead of 60.
Answer:
12 problems
Step-by-step explanation:
All problems were of equal value
Let x be the number of problems in the test
We apply a rule of three
x ------------------------------- 100%
(x-10) --------------------------- 17%
(x-10)*100%/(x) = 17%
(x-10)/(x) = 0.17
(x-10) = 0.17*x
0.83*x = 10
x = 12.05
x = 12 problems
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
Then, use the squares in the equation:
Then, subtract 100 from both sides to isolate b:
Finally, square root both sides to get your answer:
Then round to the nearest tenth which gives you 17.3.
