The side length in the y-direction is 9-6 = 3 units. (sides ab and cd)
The side length in the x-direction is 7-2 = 5 units. (sides bc and ad)
Answer:
x=26°
Step-by-step explanation:
6x+(x-2)=180 (because together they form a straight angle which is 180°)
solve:
6x+x-2=180
7x-2=180
7x=182
x=26
Answer:
2.371
Step-by-step explanation:
subtract 8.63 to 11.001
The equation is a perfect square binomial (2n+7)^2.
A typical shower drain can remove 480 gallons of water in 3 hours.
For the first-rate;
1,440 gallons in 3 hours
We calculate the unit rate.
By Dividing the total volume by the total time,
1440 / 3 = 480 gallons/ hours
For the second rate:
960 gallons in 120 minutes
Converting minutes to hours:
120 minutes = 2 hours
We calculate the unit rate.
By dividing the total volume by the total time,
960 / 2 = 480 gallons / hour
For the third rate:
720 gallons in 1.5 hours
We calculate the unit rate.
By dividing the total volume by the total time,
720 / 1.5 = 480 gallons / hour
Now,
480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute
