Answer:
12, 14
Step-by-step explanation:
To find out a distance, you must find out how far numbers are, you can use a number line for this.
Answer:
- first car: 25 mpg
- second car: 15 mpg
Step-by-step explanation:
Let x represent the fuel efficiency of the car that used the most gas. Since the sum of the fuel efficiencies is 40 mpg, the other car had a fuel efficiency of (40-x). Then the combined miles driven is ...
40x +25(40-x) = 1225
15x = 225
x = 15
(40-x) = 25
The first car got 25 miles per gallon; the second car got 15 miles per gallon.
_____
We made use of the relation ...
gallons × (miles/gallon) = miles
Answer:
F. 30 G. 8
Step-by-step explanation:
F. 9 / 9 + 6 = 18 / BC
9 + 6 = 15
9 / 15 = 18 / BC
9 x 2 = 18
15 x 2 = 30
G. 9 / 6 = 12 / EC
9/6 reduces to 3/2
3/2 = 12/EC
3 x 4 = 12
2 x 4 = 8
Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer
They would 40 miles in 5 hours traveling at 8 miles an hour
