Pablo's family began their trip with a full tank of gas in their car. They drove 384.1 miles and
stopped to fill their tank back up with gas. It took 14.2 gallons of gas to fill up their tank.
About how many miles per gallon of gasoline did they average on their trip?
Work Shown:
(384.1 miles)/(14.2 gallons) = (384.1)/(14.2) mpg = 27.049 mpg approximately
mpg = miles per gallon
Answer:
27.05 miles per gallon
Step-by-step explanation:
384.1 miles = 14.2 gallons
x = 1 gallon
14.2x = 384.1
x = 384.1/14.2
= 27.0492958
≈ 27.05 miles per gallon

To find out how fast a tree grows, you can measure its trunk. A giant red oak's diameter was 248 inches in 1965. The tree's diameter had grown to 251 inches in 2005. Find the average rate of change in the diameter of the tree per year.
CLEAR CHECK
1313 inches per year
-0.075 inch per year
0.075 inch per year
3 inches per year
I think it's 0.075 inch per year
Answer:
Your answer is C. or 0.075 inches per year.
Step-by-step explanation:
251-248 = 3 ( To figure out how much it grew )
2005 -1965 = 40 ( To figure out how long it took )
3/40 = 0.075

5. The length of a red rectangle is 12 cm more than its width, w. A blue
rectangle, which is 4 cm wider and 2 cm shorter than the red one, has
perimeter 72 cm. Make a sketch of the rectangles expressing all dimensions in
terms of w. Then find the dimensions of the red rectangle.
Answer:
For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.
Step-by-step explanation:
Red triangle: width is 9 cm, length is 24 cm, blue one width is 14 cm and the length is 22 cm. hope this helps. did this quickly! <3
Answer:
Step 1. Perimeter P means adding up all 4 sides of a rectangle.
Step 2. Let w be the width of the red rectangle
Step 3. Let w+15 be the length of the red rectangle
Step 4. Let w+5 be the width of the blue rectangle
Step 5. Let w+15-2=w+13 be the length of the blue rectangle
Step 6. Then for the blue rectangle, P=w+5+w+5+w+13+w+13=4w+36=72
Step 7. Solving 4w+36=72
Subtract 36 from both sides of the equation
4w=36
Divide by 4 to both sides of the equation
ANSWER: For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.
