Answer:
He can go 10.78 miles
Step-by-step explanation:
This problem can be solve by creating a proportion, knowing that 15.4 miles is to one gallon the same as "x" miles (our unknown) is to 0.7 gallons. This can be set in math terms as the equation that relates these two ratios of miles per gallon:
and to solve for the unknown number of mile, we multiply both sides of the equation by "0.7 gallon" in order to isolate our unknown:
The driver has to drive 20 miles to come back to the starting point directly
Step-by-step explanation:
The driver has driven in the form of two legs on a right-angled triangle where the vertical side (perpendicular) is 12 miles and the horizontal side (base) is 16 miles.
Now as the driver has to return back to the starting point directly, it will form a right-angled triangle making the direct path a hypotenuse
So,
B = 16
P = 12
H = ?
we have to find the hypotenuse
As the triangle is a right angled triangle, we can use the Pythagoras theorem to find the length of hypotenuse So,
taking Square root on both sides
So
The driver has to drive 20 miles to come back to the starting point directly

Answer: Undefined
Step-by-step explanation:
For this problem, we know that 3ˣ=-9. All we have to do is figure out what x is.
We know that any integer raised to the power cannot be negative. The closest answer we can get is x=2 because 3²=9. Unfortunately, we are looking for -9. Therefore, this x is undefined.
