Step-by-step explanation:
For fraction multiplication, multiply the numerators and then multiply the denominators to get
4×97×20=36140
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 36 and 140 using
GCF(36,140) = 4
36÷4140÷4=935
Therefore:
47×920=935
Solution by Formulas
Apply the fractions formula for multiplication, to
47×920
and solve
4×97×20
=36140
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(36,140) = 4
36÷4140÷4=935
Therefore:
4/7×9/20=9/35

Step-by-step explanation:
well first 2(2x-5) turns to 4x-10 because of distributive prperty
then simplify the other side 3x+x-2x to 4x-2x to 2x
then subtract 4x from both sides and you get -10= -2x
after divied -2x/-2 and -10/-5
and get x=5
then plug in 5 into x to make sure both sides are equal
and they equal 10=10
Determine the slope of line (AB) and the slope of line (CD). Determine whether line (AB) and line (CD) are parallel, perpendicular, or just intersecting (neither). Points A and B line on the line y = 2/3x + 4. Points C and D line on the line 6x + 4y = 16.
Answer:
The slopes are perpendicular
Step-by-step explanation:
Points A and B line on the line y = 2/3x + 4.
This line is in the form
y = mx+b where m is the slope
The slope is 2/3
Points C and D line on the line 6x + 4y = 16.
Solve for y
6x+4y = 16
4y = -6x +16
Divide by 4
4y/4 = -6/4x + 16/4
y = -3/2 x +4
The slope is -3/2
The slopes multiply to -1
2/3 * -3/2 = -1
so they are perpendicular

What is the value of y?
Maria and John decide to shop for furnishings for the new house. They choose items that amount to $5600.00. The store has 2 fixed installment simple interest loan options for purchasing:
Option 1: 20% down payment and financing at 5% simple interest per year for 3 years.
Option 2: no down payment and financing at 5.25% simple interest for 4 years.
Answer each of the following questions separately, showing all your work to reach each answer.
A. Which option will result in smaller finance charge (interest)? What will that finance charge/interest be?
B. Which option will result in the smaller monthly payment on this fixed installment loan? What will that monthly payment be?
C. They decide to defer any purchases and invest a $5600 bonus that Maria will be getting from work in a savings account. The APR is 21.6% compounded monthly. How much interest will they earn in 4 years?
D. They decide to defer any purchases and loan the $5600 bonus to a needy relative at 1.5% simple interest per year. How long will the term of the loan need to be if they want to earn $500 in interest (assuming the loan is not paid off early).
Answer:
A. The option that results in the smaller finance charge/interest is option 1
B. The option that will result in the smaller monthly payment is option 1
C. The interest they will earn in 4 years, I = $6,643.972
D. The time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years
Step-by-step explanation:
A. The simple interest, I, formula is given as follows;
[tex]I = \dfrac{P \times R \times T }{100}[/tex]
Where;
P = The principal
R = The rate
T =The time given for the loan
For Option 1 the first option, we have;
Down payment = 0.2 × $5600.00 = $1,120.00
Principal = $5600.00 - $1,120.00 = $4,480.00
[tex]\therefore I = \dfrac{\$ 4480\times 5 \times 3 }{100} = \$672[/tex]
For Option 2. the second option, we have;
P = $5600.00
[tex]\therefore I = \dfrac{\$ 5600 \times 5.25 \times 3 }{100} = \$1176[/tex]
The option that results in the smaller finance charge is option 1
B. For option 1, the total amount = Principal + Interest
∴ The total amount remaining = $4480 + $672 = $5,152
The monthly payment = A/N
Where;
A = The total amount yet to be paid out of the loan = $5,152
N = The number of time periods = 3 × 12 = 36 months
The monthly payment = $5,152/36 = [tex]\$ 143.\overline{111}[/tex]
For option 2, the total amount = Principal + Interest
∴ The total amount remaining = $5,600 + $1176 = $6776
The monthly payment = A/N
Where;
A = The total amount yet to be paid out of the loan = $6,776
N = The number of time periods = 3 × 12 = 36 months
The monthly payment = $6,776/36 = [tex]\$ 188.\overline{222}[/tex]
Therefore, the option that will result in the smaller monthly payment is option 1
C. For a compound interest on a principal of $5,600 invested for 4 years in a savings account that gives an interest rate 21.6% per annum, we have;
[tex]A = P \times \left(1 + \dfrac{r}{n} \right)^{(n\times t)}[/tex]
We have, using the annual rate, rather than calculating for the monthly rate;
[tex]A = 5600 \times \left(1 + 0.216 \right)^{4} \approx 12243.972[/tex]
Therefore, the amount they will have in 4 years ≈ $ 12,243.972
The interest they will earn in 4 years, I = A - P ≈ $ 12,243.972 - $5,600 = $6,643.972
The interest they will earn in 4 years, I = $6,643.972
D. To earn an interest of $500 at an interest rate of 1.5%, we have;
[tex]500 = \dfrac{5600 \times 1.5 \times T}{100} = 84 \times T[/tex]
From which we have;
[tex]T = \dfrac{500}{84} = \dfrac{125}{21} = 5\frac{20}{21} \approx 5.95[/tex]
Therefore, the time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years.
Photos and videos have become an important part of the online social experience, with more than half of Internet users posting photos or videos online that they have taken themselves. Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves. A research center finds that P(A) = 0.47, P(B) = 0.28,and P(A or B) = 0.52.
Required:
What is the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves?
Answer:
0.82
Step-by-step explanation:
Given:
A be the event that an Internet user posts photos taken by themselves.
B be the event that an Internet user posts photos taken by themselves.
P(A) = 0.47
P(A) = 0.28
P(A or B) = [tex]P(A\cup B)[/tex] = 0.52
To find:
Conditional probability that an Internet user posts photos given that they post videos.
OR
P(A/B) = ?
Solution:
Formula to be used to find the required conditional probability:
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
For this, [tex]P(A \cap B)[/tex] is required.
Formula
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
[tex]0.52=0.47+0.28-P(A\cap B)\\\Rightarrow P(A\cap B)=0.23[/tex]
Now, the required conditional probability is:
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}\\\Rightarrow P(A/B) = \dfrac{0.23}{0.28}\\\Rightarrow \bold{P(A/B)} = 0.82}[/tex]
So, the answer is 0.82.
Task #4: Waiting in Line You’re attending a concert with five friends but each of you arrived at the venue at different times. The fractions below tell how much of the distance they have already moved since they got in line. (Think about fractions as area models if you need some help!) You 3 / 4 Andrea 1/ 2 Bart 4 /5 Camden 7 /8 Drake 3/ 7 Ethan 2 /3 1. Who do you know is not going to get in the gate first? 2. How do you know? 3. Who is getting in the gate first? Who is getting in the gate last?
Step-by-step explanation:
Given data:
You = 3/4
Andrea = 1/2
Bart = 4/5
Camden = 7/8
Drake = 3/7
Ethan = 2/3
1. Drake would not be getting into the gate first because he is far behind at 3/7.
2. each fraction represents how far each have travelled Or moved on the line. Just like how you have move 3/4 on the line which represents three quarter of the line, and Andrea has moved half way through the line at 1/2.
3. Camden 7/8 would get to the get first and Drake 3/7 would get in last.
Which equation can be used to graph the line that passes through (6,15) and is perpendicular to the graph y-7= 1/2 (x+2)
Answer:
Option A. y = –2x + 27
Step-by-step explanation:
y – 7 = ½(x + 2)
We'll begin by calculating the slope of the equation above. This can be obtained as follow:
y – 7 = ½(x + 2)
Clear bracket
y – 7 = ½x + 1
Rearrange
y = ½x + 1 + 7
y = ½x + 8
Comparing
y = ½x + 8
with
y = mx + c
The slope (m) = ½
Next, we shall determine the slope (m2) of the equation perpendicular to the line. This can be obtained as follow:
For perpendicularity,
m1 × m2 = –1
m1 = ½
½ × m2 = –1
m2 /2 = –1
Cross multiply
m2 = 2 × –1
m2 = –2
Therefore, the slope of the equation perpendicular to the line is –2
Finally, we obtained the equation of the line as follow:
Coordinate = (6, 15)
x1 coordinate = 6
y1 coordinate = 15
Slope (m) = –2
y – y1 = m(x – x1)
y – 15 = –2(x – 6)
Clear bracket
y – 15 = –2x + 12
Rearrange
y = –2x + 12 + 15
y = –2x + 27
Therefore, the equation is y = –2x + 27

kest kuy is offering a sale on its laptop computers with a 20 percent discount off its original price. there is 8% sales tax added to the discounted price to get the final price of the computer. if x is the original price and y is the final price, write an equation to determine the final price based upon the original price.
Answer:
[tex]y = 0.88x[/tex]
Step-by-step explanation:
Given
[tex]Discount = 20\%[/tex]
[tex]Sales\ Tax = 8\%[/tex]
Required
Determine the final price
First, we need to determine the sales price after the discount.
[tex]Discount = 20\% * x[/tex]
[tex]Discount = 0.20 * x[/tex]
[tex]Discount = 0.20x[/tex]
[tex]Sales\ Price = x - Discount[/tex]
[tex]Sales\ Price = x - 0.20x[/tex]
[tex]Sales\ Price = 0.80x[/tex]
Next, is to determine the sales tax.
[tex]Sales\ Tax = 8\% * x[/tex]
[tex]Sales\ Tax = 0.08 * x[/tex]
[tex]Sales\ Tax = 0.08x[/tex]
Final Price, y is then calculated as thus:
[tex]y = Sales\ Price + Sales\ Tax[/tex]
[tex]y = 0.80x + 0.08x[/tex]
[tex]y = 0.88x[/tex]
