The unit rate of the bicyclist's speed is found by dividing the distance covered (1/5 mile) by the time spent (1/65 hour). The result is 13 miles per hour.
In this problem, you're asked to find a unit rate. A unit rate is a rate in which the second term is 1. So, to find a unit rate, you divide the first term with the second term.
In this case, the bicyclist's rate is 1/5 mile in 1/65 hour. If you divide 1/5 by 1/65, you find the rate of bicycle speed per 1 hour, which is the unit rate:
1/5 miles divided by 1/65 hours = (1/5) * (65/1) = 13 miles/hour
So, the bicyclist's unit rate is 13 miles per hour.

3.) 5pSquare - 8q +2p -20q
The sum of the measures of the interior angles of a triangle is 180 degrees.
Make the three angles add up to 180 in an equation.
6x + 130 + 4x = 180
Combine like terms.
10x + 130 = 180
Subtract 130 from both sides.
10x = 50
Divide both sides by 10.
x = 5 is your answer.
Answer:
39.275 or 39 R 3
Step-by-step explanation:
Hope it helped!
we are given
Area:
side=a=19
we know that
area of square = side*side
now, we can plug value
and we get
Perimeter:
perimeter=4a
Formula for perimeter of a square: P = 4a
Formula for area of a square: A = a²
a is given as:
19
Plug this value for a into the above formulas to solve for perimeter and area.
P = 4a
P = 4(19)
P = 76
-----------------------------------------------------------------------------------------------------------------
A = a²
A = 19²
A = 361
Answer:
P = 76 units; A = 361 units².
