The unit rate of road construction is 2 miles per day.
Step-by-step explanation:
Given,
In 
days 
miles road is constructed.
To find
The rate of road constructed per day
Method
We will apply unitary method to solve it.
Now,
In days miles road is constructed.
In 1 day the road will be constructed = ÷ miles
= 2 miles
101.65 x .30= 30.50 saving
so take 101.65 - 30.50= 71.15
Answer:
14 divided by 4139 is 0.0033824595312878
Step-by-step explanation:
Answer:
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Step-by-step explanation:
Mai biked 5 1/4 miles today
So he biked, in miles:
Noah biked 2 1/2 miles.
So, in miles, he biked:
How many times the length of Noah’s bike ride was Mai’s bike ride?
We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Answer:
angle A is 63 degrees,
angle B is 57 degrees
Step-by-step explanation:
first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:
2x+3+2x-3=120
now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:
4x=120
now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.
substitute the 30 into the x in the original equation, and this becomes:
60+3+60-3=120
63+57=120
thus, angle A is 63 degrees, and angle b is 57 degrees.
