Answer:
Cathy was driving at a speed of 67 miles per hour.
Step-by-step explanation:
Fined $15 for each mile per hour over the speed limit. Cathy was given a ticket for $105.
We solve this using a rule of three.
1 mile - $15
x miles - $105
Applying cross multiplication:
15x = 105
x = 105/5 = 7.
Cathy was 7 miles above the speed limit.
How fast was Cathy driving?
7 miles above the speed limit of 60 miles per hour, so 60 + 7 = 67 miles per hour.
Cathy was driving at a speed of 67 miles per hour.
Answer:
3%
Step-by-step explanation:
105 = 700 x r x 5
r = 105 / ( 700 × 5 ) = 0.03
r = 0.03
0.03 in percent is 3%
Multiply the values then either divide by 2 or multiply by 2
30
As it an equilateral so it would be 60
Its split into two 60/2 = 30
Here is the formula for find the one inside of the polygon:
(n-2).180/n (n shows how many sides does polygon have)
so now we can solve the equation==== (n-2).180/n=144
1144n=(n-2).180
144n=180n-360
360=36n
n=10
so we call it decagon :)
