Answer:
[tex]\cfrac{7}{6}[/tex]
Step-by-step explanation:
[tex]\cfrac{7}{8} \div \cfrac{3}{4}[/tex]
Divide 7/8 by 3/4 by multiplying 7/8 by the reciprocal of 3/4:
[tex]\cfrac{7}{8}\times[/tex] [tex]\dbinom{4}{3}[/tex]
Now, multiply 7/8 times 4/3 by multiplying numerator times numerator and denominator times denominator:
[tex]\cfrac{7\times 4}{8\times 3}[/tex]
Do multiplication in fraction: [tex]\cfrac{7\times 4}{8\times 3}[/tex]
[tex]\cfrac{28}{24}[/tex]
Reduce fraction [tex]\frac{28}{24}[/tex] to lowest terms by extracting and canceling 4 out:
[tex]\cfrac{7}{6}[/tex] [tex]\checkmark[/tex]

prove that 5^(2n - 1) is divisible by 8
Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.
The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.
On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.
Let's consider a few concrete examples:
If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

Line f passes through points (8, 7) and (3, 10). Line g passes through points (5, 7) and (10, 4). Are line f and line g parallel or perpendicular?
Answer: Parallel
Step-by-step explanation:
First find slope.
Line f: [tex]\frac{10-7}{3-8} =-3/5[/tex]
Line g: [tex]\frac{4-7}{10-5}=-3/5[/tex]
Since the slopes are the same, the lines are parallel.
First we need to find the slope of each line
Slope of line f
(8 , 7) (3 , 10)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{10-7}{3-8}[/tex]
[tex]slope = \frac{3}{-5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
Slope of line g
(5 , 7) (10 , 4)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{4-7}{10-5}[/tex]
[tex]slope = \frac{-3}{5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
The two lines have the same slope therefore they are not perpendicular but instead parallel to each other.

Write the decimal in expanded form using fractions
0.801 = ???
Answer: 8/10 + 1/1000
Step-by-step explanation: in decimal form we have 0.800 + 0.001
to convert this into a fraction you'd do 8/10 + 1/1000
(8 is in the tenths place therefore 8/10 and 1 is in the thousandths place therefore 1/1000)

The endpoint coordinates of AB are A(2, -10) & B(12, 5). Find the coordinates of the point that is 2/5 from A to B.

Step-by-step explanation:
solve the pattern:
15, 17, 32, 49, 81 __ __ ← those are the blank spaces.
Answer:
130 and 211
Step-by-step explanation:
15+17= 32
17+32=49
32+49=81
49+81=130
81+130=211
Answer:
130 and 211
Step-by-step explanation:
15,17,32,49,81 _ _
15+2=17+15=32+17=49+32=81
that mean 81+ 49=130
and 81+130= 211
Hence, the answer is 130 and 211.
( 8n - 3n^4 + 10n ^2 ) - ( 3n^2 + 11n ^4 - 7)
-14n⁴ + 7n² + 8n + 7
Step-by-step explanation:
(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)
= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7
= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7
= -14n⁴ + 7n² + 8n + 7
Mr. Flores opened an account with a deposit of $5,000.
• The account earned annual simple interest.
• He did not make any additional deposits or withdrawals.
• At the end of 4 years, the balance of the account was $6,500.
What is the annual interest rate on this account?
A. 5.8%
B. 7.5%
C. 3.3%
D. 1.9%
Answer:
B. 7.5%
Step-by-step explanation:
First, we need the Simple Interest (S.I)
Total = Principal + Simple Interest
T = P + S.I
6500 = 5000 + S.I
[make S.I the subject of the formula]
S.I = 6500 - 5000
S.I = 1500
Simple Interest = (Principal × Rate × Time) / 100
S.I = (P × R × T) / 100
1500 = (5000 × R × 4) / 100
1500 = 20000R / 100
1500 = 200R
[divide both sides of the equation by 200]
1500 / 200 = 200R / 200
R = 1500 / 200
R = 7.5
The annual interest rate is 7.5%
What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?
Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

30% of the swimming team are girls. If there are 18 girls. How many are in the team
altogether?
Answer:
60 people are in the team altogether
Answer:
60
Step-by-step explanation:
to find the percentage of girls on the swim team, you would multiply a number by 30 percent. to find the number in all, you would divide 18 by 30 percent
18/0.3 = 60
there are sixty people on the swimming team
How to find perimeter with equations
I attached a pic of the problem I’m really struggling with, if I could get a step by step explanation of how to do it that would be great. Thanks so much
Step-by-step explanation:
In blue colour square
Perimeter= 4 × side
= 4 (3x +7)
=12x +28 unit
In green colour square
Perimeter= 4 × side
= 4 ( 5x+1)
= 20x +4 unit
Answer:
12x + 28 = p
20x + 4 = p
Step-by-step explanation:
Assuming that both shapes are square, the perimeter of a square is the equation:
4 * x = p
Where x is the length of one side. Plug the variables in for the first square:
4 * (3x + 7) = p
Expand the brackets:
4 * 3x = 12x
4 * 7 = 28
12x + 28 = p
For the second square, plug the variables in again:
4 * (5x + 1) = p
Expand the brackets:
4 * 5x = 20x
4 * 1 = 4
20x + 4 = p

Answer:
36/32 or 1 1/8 (same thing)
Step-by-step explanation:
9 gallon / 32 quarts
First, you have to convert 9 gallon to quarts to match the denominator. In the table, it says that 1 gallon = 4 quarts, so you have to do, 9 x 4 which gives you 36. Now that the fraction is in the same form of units, 36 quarts / 32 quarts, you will have to write it as a mix fraction or you can just leave it as 36 quarts / 32 quarts. If you want it in mix fraction, it is 1 1/8.
Answer:
36
Step-by-step explanation:
1 gallon is 4 quart then the question is 1 to 9 quart then is 4 * 9 is 36
