Find miles per hour by dividing total miles by total time:
240 miles / 3 hours = 80 miles per hour.
Now multiply miles per hour by time:
80 miles per hour x 2 hours = 160 miles.
The answer is 160 miles.
Answer: x = 20 units
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem (c is the hypotenuse and a & b are the legs.);
a² + b² = c²
a² + b² = c²
(21)² + (x)² = (29)²
441 + (x)² = 841
(x)² = 400
x =
= 20
The answer is the third one!!
Answer:
3.9 * 10^-2
Step-by-step explanation:
We need a number between 0 and 10, so we need to multiply.
0.039 * 10 = 0.39
0.39 * 10 = 3.9
Since 0.039 is less than 0, we are going to have a negative exponent.
3.9 * 10^-2
Best of Luck!
