Answer:
This problem is a great systems of equations problem--you have two different variables: song size and number of songs.
Let's call the number of standard version downloads (S) and the high quality downloads (H).
You can make two statements:
For number of songs downloaded: S + H = 910
For download size: 2.8(S) + 4.4(H) = 3044.
S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:
2.8(S) + 4.4(910 - S) = 3044
2.8S + 4004 - 4.4S = 3044
-1.6S = -960
s = 600
Your question only asks for the standard version downloads, but to help you out in future Systems situations-
You can also solve for H once you have S by plugging it into either of your equations like this:
600 + H = 910
-600
H=310

use the distributive property to multiply 3(-2m+1)
Answer:
-6m+3
Step-by-step explanation:
"use the distributive property to multiply 3(-2m+1)"
--------------------------------------------------------------------------------------------------------------
The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. The division property of inequality states that two unequal values divided by a positive number retain the same relationship.
--------------------------------------------------------------------------------------------------------------
We can simplify this into-
3(-2m) + 3(1)
Now, we can multiply.
-6m + 3

Clint is going to open up a private practice where he will make $100 per client that he sees. How many clients does he have to see each week to earn $50,000, assuming he works 48 weeks per year? (Round to two decimal places)
Answer:
10 clients per week
Step-by-step explanation:
We know that there are 4 week in a month
48/4 = 12
And we know that there are 30 days in a month.
12*30 = 360
There are 365 days in a year
360x = 50,000
x = 139 (rounded)
We know he makes $100 per clients
139*100 = $13,900
To get to $50,000 we must divide
50,000 / 13,900 = 3.6
Now multiple 139 by 3.6
139*3.6 = 500
Divide by the week worked
500/48 = 10 (rounded)
So....
48 weeks * 10 clients = 480 total clients he saw
480 clients saw * $100 = $48,000
Clint needs to see 10.42 clients each week to earn $50,000 a year.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Clint makes $100 per client that he sees.
∴ He needs to see (50000/100) clients to make $50,000.
= 500 clients per year.
Also given, he works 48 weeks a year.
∴ He needs to see (500/48) clients each week.
= 10.42 clients each week.

You and your friend got tricked into helping another friend move stuff from a garage into moving truck. The ramp used is 12 feet long and makes a 36° angle with the horizontal ground. You discover that the incline is just too steep, so you replace the ramp with one that is 32 feet long. What angle does this replacement ramp make with the ground? Round your answer to the nearest tenth of a degree
Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the the distance and length of the ramp is but the height stays the same.
We draw our right triangle, see photo
We really only care about finding out what side a is so
[tex]c = \frac{a}{ \sin(x) } [/tex]
Note: Let x = A
[tex]12 = \frac{a}{ \sin(36) } [/tex]
[tex]12 \sin(36) = a \\ a = 7.05342302750[/tex]
[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{12} ) \\ = 35.9999 \: degrees[/tex]
So, since I stated that height did not change, same process just using 32 for the hypotenuse.
[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{32} ) \\ = 12.73367164 \: \: degrees[/tex]
Find the volume, in cubic centimeters, of the rectangular prism pictured below.
Answer:
V= 18.75 cm^3
Step-by-step explanation:
The formula for finding the volume for any given shape is V = L x W x H.So, multiply 2 1/2 cm x 2 1/2 cm x 3 cm.This gives you 18.75 cm^3If the radius of a circle is one what is the sin and cosine
The unit circle is a circle with radius 1 centered at the origin of the Cartesian Plane. In a pair of coordinates (x,y) on the unit circle x2+y2=1, coordinate x is the cosine of the angle formed by the point, the origin, and the x-axis. Coordinate y is the sine of the angle.

Quadrilateral IJKL is dilated by a scale factor of to form quadrilateral I'J'K'L'. What
is the measure of side LI?
Answer:
The measurement of side LI = 24
Step-by-step explanation:
In the question, it is given that Quadrilateral IJKL is reduced to quadrilateral I'J'K'L' which is 1/2 the times of measurement of side of the Quadrilateral IJKL
I'L' = 12
And IL will be 2 times the measurement of I'L'
Hence, IL = 2*12 = 24
