Mark is having birthday party.he brought 8 pizzas to be shared equally among 40 people. Which two equivalent representation could be use to determine how much pizzas each guest will receive
8÷40 = 40/8
8÷40= 8/40
40÷8= 40/8
40÷8= 8/40
Which fraction is greater than 1/2
A.) 5/8 B.) 4/8 C.) 1/8 D.) 3/8
Answer:
A. 5/8
Step-by-step explanation:
If you want to find the equivalent of 1/2 in 8ths, what times 2 will give you 8? The answer is 4, so multiply the numerator and denominator by 4 to get 4/8. So, 4/8 is equal to 1/2, meaning that 5/8 is greater than 4/8. Hope this helped!
Lorena borrowed $1950 to buy books and a tablet for her freshman year of college. She will pay off the loan in 10 months at an annual simple interest rate of 5.75%. How much interest will she be charged and what is the total amount she must pay at the end of the 10 months? Round your answer to the nearest cent.
Answer:
Step-by-step explanation:
Simple Interest = Principal * Rate * Time/100
Given
Principal (amount borrowed) = $1950
Rate = 5.75%
Time = 10month
Convert time to year
To do that, we will divide the value in months by 12 i.e Time = 10/12
Time = 5/6 years
Substitute into the formula and find the simple interest
SI = (1950 * 5.75*5/6)/100
SI = (1950 * 5.75*5)/600
SI = 56,062.5/600
SI = $93.4375
Hence she will be charged interest of $93.4375
To get the total amount after 10 months, we will use the formula;
Amount = Principal + Interest
Amount = $1950 + $93.4375
Amount = 2,043.4375
Hence she must pay back $2,043.4375 after 10 months
Put the following equation of a line into slope-intercept form
2x - 2y = 6
Answer:
Y=-2x+3
Step-by-step explanation:
2x-2y=6
2y=-2×+6
y=-2×+6/2
y=-2x+3
The equation of a line into slope-intercept form is y = x - 3
The standard form of an equation in slope-intercept form is expressed using the equation y = mx + b
m is the slope of the line
b is the y-intecept
Given the equation 2x - 2y = 6
Divide through by 2
x - y = 3
-y = -x + 3
Multiply through by -1
-(-y) = -(-x) + (-3)
y = x - 3
Hence the equation of a line into slope-intercept form is y = x - 3

It takes 47 pounds of seed to completely plant a 7-acre field. How many pounds of seed are needed per acre?
Answer:
6.71428571429 (!!!)
OR
6.71 (Rounded to the nearest hundredth)
Step-by-step explanation:
PLEASE KNOW THAT I AM UNSURE.
I think it is 47 divided by 7, but the answer is very long and unrealistic, so it may be wrong. You could try rounding it to the nearest hundredth, which would be 6.71 pounds. Maybe wait for another answer, because this could be wrong!!
How to Solve X-3/8= 7/16
Answer:
x=13/16
Step-by-step explanation:
The question is asking us to isolate the variable x. This means that we need to add -3/8 to both sides of the equation. Because the denominators of the fractions 3/8 and 7/16 are not the same, we need to find a common denominator, which is 16. (So we change 3/8 to 6/16 because the two fractions are equal). Now that we have the fractions 6/16 and 7/16 we can add the two to get x=13/16
Lavonda took out a $7,500 loan with an APR of 3.875\% and agreed to pay it back monthly over 6 years
What is her monthly payment?
How much will she pay back in total?
What is the finance charge?
Answer:
Step-by-step explanation:
Given data
principal=$7500
rate= 3.875%= 0.03875
time =6years
The expression for the final amount for a simple interest is
A=p(1+rt)
A=7500(1+0.03875*6)
A=7500(1+0.2325)
A=7500(1.2325)
A=9243.75
$19243.75
1. What is her monthly payment?
given that it is spread over 6 years
there are 12*6 months= 72months
monthly pay=9243.75/72= $128.38
2. How much will she pay back in total?
=$19243.75
3. What is the finance charge?
the finance charge is the interest which is

The formula for the area of a triangle is A= 1/2 bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base if the area is 22cm? and the height is 8 cm?
Answer:
The length of the base = 5.5cm.
Step-by-step explanation:
A = 1/2 bh
A = 22cm^2 h = 8cm.
22 = 1/2 b(8)
22 = 4b
hence b = 5.5cm.

Danny bought 10 plastic disas. Each disc weighs 0.9 ounces. How much do the 10 plastic discs weigh in all?
Answer:
9
Step-by-step explanation:
Answer:
9 ounces
Step-by-step explanation:
In this equation, we are given two things. We know how much each disc weighs (.9 ounces) and we know how many discs Danny bought (10 discs).
To figure out how much the discs weigh, we must do the following steps:
We first step up the equation: 10 discs times .9 ounces
Then, we multiply the numbers to get our final answer: 10(.9 ounces)= 9 ounces
The 10 discs weigh a total of 9 ounces.

over a long time, cable from acme cable co has a mean strength of 37.5 ksi with a known population standard deviation of 1 ksi. find the probability that a random piece of th ecable has a strength x lower than 36.0 ksi
Answer:
The value is
[tex]P(X < 36) = 0.066807[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 37.5 \ ksi[/tex]
The standard deviation is [tex]\sigma = 1 \ ksi[/tex]
Generally the probability that a random piece of the cable has a strength x lower than 36.0 ksi is mathematically represented as
[tex]P(X < 36) = P(\frac{X - \mu}{ \sigma } < \frac{ 36 - 37.5}{1} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 36) = P(Z < -1.5 )[/tex]
From the z table the probability of [tex](Z < -1.5)[/tex] is
[tex]P(Z < -1.5) = 0.066807[/tex]
So
[tex]P(X < 36) = 0.066807[/tex]
What is the probability a server will refuse to serve alcoholic beverages to exactly 2 minors if he randomly checks the IDs of 5 of the 9 students in the establishment, and 4 of the 9 students are minors?
Answer:
10/21
Step-by-step explanation:
Probability = Expected outcome/total outcome
If he randomly checks the IDs of 5 of the 9 students in the establishment, the total outcome will be expressed as:
9C5 = 9!/4!5!
9C5 = 9×8×7×6×5!/5!×24
9C5 = 9×8×7×6/24
9C5 = 126
Total outcome = 126
For the expected
First we know that 4out of 9 students are minor, and we want to know the probability that exactly 2 are minor, this can be done in 4C2 ways
4C2 = 4!/2!2!
4C2 = 4×3×2/4
4C2 = 6
Also since 4 out of 9 are minor, then 5 are not minor and if out of every 5, exactly two are minor, then 3 are not.
Those not minor can be expressed in 5C3 ways
5C3 = 5!/2!3!
5C3 = 5×4×3!/2×3!
5C3 = 20/2
5C3 = 10
Total expected outcome = 4C2 × 5C3
Total expected outcome= 6×10 = 60
Hence, the probability a server will refuse to serve alcoholic beverages to exactly 2 minors will be;
= 60/126
= 30/63
= 10/21
