Find how far the car can travel on one gallon of gas, by dividing total miles by number of gallons:

105 miles / 7 gallons = 15 miles per gallon.

Now multiply that by the number of gallons to find total miles:

15 miles per gallon x 9 gallons = 135 total miles.

For what value of x is the area of the rectangle greater than the perimeter? The base of the perimeter is x+2

TiliK225 [7]

If we call the area A, then $A=7(x+2)=7x+14$
if we call the perimeter P, then $P=7*2+2(x+2)=2x+18$
$A>P$
$7x+14>2x+18$
subtracting 14 gives $7x>2x+4$
subtracting 2x gives $5x>4$
dividing by 5 gives $x>\frac{4}{5}$
or $x>0.8$

Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 5:8. How many times did she miss?

Digiron [165]

Answer: She misses 56 times at a soccer practice.

Step-by-step explanation:

Let the goals she misses be 'x'.

According to the question:

$5:8::35:x$

These two ratios follow direct relationship, so:

$\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56$

Hence, Vonna misses 56 times at a soccer practice.

Determine whether the ratios 35 feet every 15 seconds and 7 feet every 2 seconds are equivalent.

murzikaleks [220]

Answer:

Step-by-step explanation:

Find the rate of those two statements:

28 ÷ 16 = 1.75

1.75 ft per seconds

7 ÷ 4 = 1.75

1.75 ft per seconds

Two statements have the same rate, therefore 28 feet every 16 seconds and 7 feet every 4 seconds are equivalent
