At Middle school ,60% of the 800 students participate in music. How many students participate in music.???
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

H(-4)=x^2-8x please solve
Answer:
Putting h=-4 in the function [tex]h(x)=x^2-8x[/tex] we get [tex]\mathbf{h(-4)=48}[/tex]
Step-by-step explanation:
We are given: [tex]h(x)=x^2-8x[/tex]
We need to find h(-4)
Put x= -4 and solve:
[tex]h(x)=x^2-8x\\Put \ x=-4\\h(-4)=(-4)^2-8(-4)\\h(-4)=16+32\\h(-4)=48[/tex]
So, putting h=-4 in the function [tex]h(x)=x^2-8x[/tex] we get [tex]\mathbf{h(-4)=48}[/tex]
If a roof has a pitch of 5 to 11, how high will the roof rise over a 33-foot run?
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. Because some times I get thinmgs wrong if I don't remember them so I need someone to explain how to do it

Answer:
5.831
Step-by-step explanation:
Pythagoras says RS = √(5²+3²) = √34 ≈ 5.831
Answer:
RS ≈ 5.83 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here RS is the hypotenuse and the legs have measure 5 and 3, thus
RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )
RS = [tex]\sqrt{34}[/tex] ≈ 5.83 ( to 3 significant figures )

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?
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.

True or false: The solutions to y is greater than mx+b always lie above the graph of the line y=mx+ b.
Answer: i think the answer is false because if The solutions to y is greater than mx+b => y > mx + b, but to lie above the graph of the line y = mx +b, y must equal to mx + b => the solutions to y isnt greater than mx+b
Step-by-step explanation:
Answer:
true if its greater

A loan of $12,000 is made at 5.25% interest, compounded annually. After how many years will the amount due reach $22,000 or more?
Answer:
About 16 years
Step-by-step explanation:
First we need to figure out 5.25% of 12000
5.25 x 0.12000 = 0.63
Then we move the decimal
630
Then we need to figure out how many years it will take to reach $22000
Since we already owe $12000, we can just divide using $10000 because 10000 + 12000 = 22000
10000/630 = 15.87
Which is about 16 years

Emma spent $16.00 on her order at Panera Bread. In her state, there is a 10% tax on food. What was her total bill after sales tax?
i need this answered so don't screw around btw its worth a lot of points :D
Answer:
$17.60
Step-by-step explanation:
We know that Emma spent $16.00 on her food.
There is a 10% tax.
Therefore, the total bill will be the price without tax plus the tax.
The price without tax is $16.00.
Tax is 10%. So, the tax will be 10% of 16.
10% of 16 is the same as 0.1(16) or 1.6.
So, the tax is $1.60.
Therefore, the total bill is:
$16.00+$1.60=$17.60.
Emma’s total bill comes to $17.60

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?
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.

Find f(2 + x) If f(x) = 4x - 5
Answer:
Replacing x with 3 in 4x-5 tells us f(3) = 7
Step-by-step explanation:
to evaluate f (3), just replace all x in f(x) = 4x - 5 with 3 :
f(3) =4(3) - 5 = 12 - 5= 7
