Answer:
2, 7, 15, 19, 34
Step-by-step explanation:
First, we have to know what a multiple is. A multiple is a number (n) that can be evenly divided by a certain base number (b). An evenly divided number is one that has no decimal points (ex: 1, 100, 24). For example, the multiples of 8 (b) would be 16, 24, 32, etc (n). Another example would be that 32 is a multiple of 2, 8, 16, etc. since it can be evenly divided by those numbers.
In this case, n = each of the numbers in that list, while b = 4. So now we just have to look at what numbers in our list can be evenly divided by 4.
2 is not a multiple since it cannot be evenly divided by 4, since it is less than 4.4 is a multiple of 4, since 4/4 = 1, and 1 is evenly divided.7 cannot be evenly divided by 4, and thus is not a multiple of 4.8 can be evenly divided by 4, since 8/4 = 2, and thus is a multiple of 4.12 can be evenly divided by 4, since 12/4 = 3, and thus is a multiple of 415 cannot be evenly divided by 4, and thus is not a multiple of 419 cannot be evenly divided by 4, and thus is not a multiple of 4.24 can be evenly divided by 4, since 24/4 = 6, and thus is a multiple of 4.34 cannot be evenly divided by 4, and thus is not a multiple of 4Since we're asked to find the numbers that are not multiples of 4, our answer to the question would be:
2, 7, 15, 19, 34

Step-by-step explanation:
A small pool is being drained. There are 1,320 gallons of water remaining in the pool after 2 minutes and 1,040 gallons after 9 minutes.
Answer:
Answer: 35 minutes
Step-by-step explanation:
Step-by-step explanation:
For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:
= (1320 - 1040) / (9 - 2)
= 280/7
= 40 gallons per minute
Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:
= 1320 gallons + (40 × 2)
= 1320 gallons + 80 gallons
= 1400 gallons
The time taken for the pool to be completely drained will be:
= Total water in pool / Gallons drained per minute
= 1400 / 40
= 35 minutes
Answer:
35 minutes
Step-by-step explanation:
There are 40 gallons drained per minute.

3. You purchase a car using a $20,000 loan with a 5% simple interest rate.
(a) Suppose you pay the loan off after 4 years. How much interest do you pay on your loan? Show your work.
(b) Suppose you pay the loan off after 2 years. How much interest do you save by paying the loan off sooner? Show your work.
Answer:
Answer:
a) $4000
b) $2000
Step-by-step explanation:
a)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 4
interest = 4000
b)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 2
interest = 2000
you save $2000 if you pay after 2 years

An exponential relationship is modeled by y = 31(0.81)x , what is the percent rate of change for this function?
Answer:
19%
Step-by-step explanation:
An exponential relationship is modeled by y = 31(0.81)^x , what is the percent rate of change for this function?
From the above exponential relationship given, we can see that this exponential relationship is an exponential decrease.
Where the formula:
y = a(1 - r)^t
Where a = Initial amount
r = rate of change in percent
t = time in years
y = a(1 - r)^x = y = 31(0.81)^x
1 - r = 0.81
r = 1 - 0.81
r = 0.19
Converting 0.19 × 100
= 19%

1.7 × 0.5 = 0.85 + 1.7 = 2.55 Miles
2xy +3y²-6y factor the following expression
Answer:
y(2x+3y-6)
Step-by-step explanation:
2xy+ [tex]3y^{2}[/tex]-6y
Find the H.C.F
2xy= 2×x×y
3y²= 3×y×y
6y= 6×y
H.C.F= y
2xy÷y+ 3y²÷y- 6y÷y
= 2x+ 3y- 6
= y( 2x+ 3y-6)

Jasmine wants to use her savings of $1,128 to buy video games and movies. The total price of the movies she bought was $72. The video games cost $43 each. Choose the inequality that would be used to solve for the maximum number of video games Jasmine can buy with her savings.
A. 43 + 72x ≤ 1,128
B. 43 + 72x ≥ 1,128
C. 43x + 72 ≥ 1,128
D. 43x + 72 ≤ 1,128
Answer:
D. 43x + 72 ≤ 1,128
Step-by-step explanation:
She has $1,128
Total price $72
43x since its unit rate for each
43x + 72 is less than or equal to $1,128
Answer:
D. 43x + 72 ≤ 1,128

What is the equation of the line that passes through point (4. 12) and has a y-intercept
of - 2?
Answer:
7x - 2y - 4 = 0
Step-by-step explanation:
from the perpendicular equation formula,
y/a + x/b = 1
x1 = 4
y1 = 12
a = -2
b= ?
Inserting the values into the above formula,
12/-2 + 4/b = 1
-6 + 4/b = 1
4/b = 7
b = 4/7
putting a and b into the original formula,
y/-2 + x/(4/7) = 1
-y/2 + 7x/4 = 1 (×4)
-2y + 7x = 4
7x - 2y - 4 = 0
Therefore, the equation of the line is;
7x - 2y - 4 = 0

The value of a boat if depreciating at at a rate of 9% per year. In 2006 the boat was worth $17,800. Find the worth of the boat in 2013.
Answer:
The worth of boat in 2013 will be $9202.6
Step-by-step explanation:
Rate of depreciation = 9% = 0.09
Cost of Boat in 2006 =$ 17,800
Cost of Boat in 2013 = ?
Years = 2013-2006= 7 years
The formula used is: [tex]\mathbf{A=P(1+r)^{t}}[/tex]
Since the value of boat is depreciating the value of r will be r=-0.09
Here P = 17,800 , r=-0.09 and t = 7 years Finding A
[tex]A=P(1+r)^{t}\\A=17,800(1+(-0.09))^7\\A=17,800(0.91)^7\\A=17,800(0.517)\\A=9202.6[/tex]
So, the worth of boat in 2013 will be $9202.6

Write a function to represent the arithmetic sequence.
f(n)=
Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:
[tex]d = a_2-a_1 = 4-2 = 2\\d = a_3-a_2 = 6-4 = 2[/tex]
The arithmetic sequence is given by:
[tex]a_n = a_1+(n-1)d[/tex]
Putting the values
[tex]a_n = 2+(n-1)(2)\\a_n = 2+2n-2\\a_n = 2n[/tex]
Hence,
The function will be: f(n) = 2n

On a sunny day, a 4-foot red kangaroo casts a shadow that is 5 feet long. The shadow of a nearby
eucalyptus tree is 20 feet long. Find the height of the tree?
Answer:
16 feet
Step-by-step explanation:
Set up a proportion where x is the height of the tree:
[tex]\frac{4}{5}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
5x = 80
x = 16
So, the tree is 16 feet tall
