Answers
Answer:
y = 5
Step-by-step explanation:
y = mx + b
5 = 6m + b
5 = 3m + b
Take the first minus twice the second.
-5 = - b
b = 5
Substitute back to calculate m.
5 = 6m + 5
6m = 0
m = 0

At Middle school ,60% of the 800 students participate in music. How many students participate in music.???
Answers
Answer:
480
Step-by-step explanation:
800=100% value
x-60%
800/x = 100%/60%
now solve for x
(800/x)*x=(100/60)*x ( multiply both sides of the equation by x )
800=1.66666666667*x ( then we divide both sides of the equation by 1.66666666667 to get x )
480 = x
x= 480
so 60% of 800 is 480

Primo car rental agency charges $50 per day plus $0.30 per mile. Ultimo car rental agency charges $20 per day plus $0.70 per mile. Find the daily mileage for
which the Ultimo charge is twice the Primo charge.
What is the mileage?
Answers
Answer:
cdcdc
Step-by-step explanation:
Answer:
Let's assume m represents the mileage of the car.
Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.
So, the total charge for this agency = 33 + 0.20m.
Similarly total charge of the ultimo car = 17 + 0.85m.
Now we need to find the daily mileage for which the ultimo charge is four times the primo charge. So, we can set up an equation as follows:
17 + 0.85m = 4 *( 33 + 0.20m )
17 + 0.85m = 132 + 0.80m By distribution property.
17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.
17 + 0.05m = 132
17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.
0.05m = 115
Divide each by 0.05.
So, m = 2300
Hence, the daily mileage is 2300 miles.

If a roof has a pitch of 5 to 11, how high will the roof rise over a 33-foot run?
Answers
Answer:
55-11=44 and 44-11=33 so 33 it is
Step-by-step explanation:
Well, 5 to 11 is just saying 5:11 just in a different way. This (:) means (to) also. So how you get the roof to a 33 foot run is to change the 5 into a 3 and the you leave the 11 alone and then you 33 -foot run. Well I really don't really know if that is ther correct anser but if it isn't then read someone's other answer because I don't really know what kind of math this is and I really need to know what grade it is and then I will look it up on the internet.

A personal-size pizza has the radius shown in the diagram. Will the pizza fit on a plate with a radius of 10−−−√ inches or a radius of 12−−−√ inches. What is the approximate value of each radius?
Answers
9514 1404 393
Answer:
fits on a plate with radius √12√10 ≈ 3.16; √12 ≈ 3.46Step-by-step explanation:
A calculator can tell you the values of the square roots:
√10 ≈ 3.16
√12 ≈ 3.46
The radius of the pizza is larger than √10, so will not fit on that plate. It is less than √12, so will fit on a plate with radius √12.
