Answer:
2) 520
3) 135
4) 490
5) 850
Step-by-step explanation:
2) 10 regular for every 2 premium. so 12 total. Then we do 624 divided by 12 so we get 52. So we multiply 10 by 52 and 520. So they have 520 regular subscribers.
3) 3 short sleeves for every 9 long sleeves. So 12 in total. 540 divided by 12 is 45. 45 times 3 is 135. So 135 short sleeves were sold.
4) 7 teens for every 2 adults. so 9 in total. 630 divided by 9 is 70. 70 times 7 is 490. So 490 of the people who voted were teens.
5) For every 10 songs he like there was 5 he disliked. So 15 in total. 1275 divided by 15 is 85. 85 times 10 is 850. He liked a total of 850 songs.

You invest $4000 into an account that compounds interest on a quarterly basis at 3%. how much money will you have after 5 years? Compound interest formula: A = P(1+r/n)^(nt)

Step-by-step explanation:
So sorry if this is wrong i tried
The amount after 5 years is $4,644.74.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P[tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $4000
n = 4
r = 3%
t = 5 years
A = 4000 [tex](1 + 0.03/4)^{20}[/tex]
A = 4000 x [tex]1.0075^{20}[/tex]
A = $4,644.74
Thus,
The amount after 5 years is $4,644.74.

In what ways are linear functions and exponential functions the same? In what ways are they different? How can they be used to model real world situations?
Answer:
In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier- it will never be the same but there will be a pattern. Exponential functions are used in real world situations such as bacterial growth/decay, population growth/decline, and compound interest. Linear functions/equations can be used for comparing rates of pay. Hope this helped!

The larger triangle is 5 times the size of the smaller triangle. Notice 6 increased to 30. How? 5x6 = 30, so it increased in size 5 times. The rise of the larger triangle is 15. If we know that 15 is 5 times as large as the smaller rise, then 15 divided by 5 = 3. So the smaller rise is 3

Answer:
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]
Step-by-step explanation:
We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
Solving for [tex]y[/tex], we get:
[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]
[tex]12*y=6.5*4[/tex] (Cross-Products Property)
[tex]12y=26[/tex] (Simplify)
[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)
[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)
