Answer:
180 minutes
Step-by-step explanation:
Starting with the distance formula ...
d = rt
dividing by the coefficient of t will give an equation for t:
t = d/r
Ryan's rate of 4 miles per hour can be expressed in minutes as 4 miles per 60 minutes. The Ryan's time is ...
t = (12 mi)/(4 mi/60 min) = 12·60/4 min = 180 min
Ryan's time is 180 minutes.
Step-by-step explanation:
Answer:
You could find the unit rate by dividing the first term of the ratio by the second term.
Answer:
156 inches^2
Step-by-step explanation:
The area of a triangle is 1/2 base x height
All of the triangles have a base of 6 inches and a height of 10 inches.
so 1/2 6 x 10= 30
There are 4 triangles with an area of 30 square inches
and then the square in the middle has a length of 6 in and a width of 6 in so it has an area of 36 in^2
so in total you would have 30+30+30+30+36, or 156
Answer:
5 is the answer. hope this help you
So he has to sell it at 19.5+2=21.5 dollars
so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%
so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so
19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup
