Help!!! Huge milestone!! I will give crown!!! The value of y is directly proportional to the value of x. If y=8 when x=10, what is the value of y when x=25?
Answer:30
Step-by-step explanation:the initial statement is
y ∝ x
to convert to an equation multiply by k the constant
of variation
⇒ y = k x
to find k use the given condition
y = − 24 when x = 8 y = k x ⇒ k = y x = −22
∣
∣
∣22 y = − 3 x 22
∣∣∣
−−−−−−−−−−−−−−
when x = 10
then y = − 3 × 10 = −30
4/6 + 1/3 please help i need to get my grade up qwq
Explanation:
1/3 is the same as 2/6
Imagine cutting a cake into thirds, then cutting each piece in two parts, so you'll have 6 pieces total. If you shade one third of the cake, then this is the same as shading 2/6 of a cake. The diagram shows this below.
Therefore 4/6 + 1/3 is the same as 4/6 + 2/6
At this point, we add the numerators over the common denominator
4/6 + 2/6 = (4+2)/6 = 6/6 = 1
Meaning we get a full cake since 4/6 is four slices and 2/6 is another two slices leading to 4+2 = 6 slices total out of the 6 overall.

A line passes through the point (8,4) and has a slope of -3/4 Write an equation in slope-intercept form for this line.
Step-by-step explanation:
Hey there!
Given;
The line passed through point (8,4) and made slope (-3/4).
Note: Use one-point formula.
[tex](y - y1) = m(x - x1)[/tex]
Put all values.
[tex](y - 4) = \frac{ - 3}{4} (x - 8)[/tex]
[tex]y - 4 = - \frac{3}{4} x - \frac{3}{4} \times - 8[/tex]
[tex]y - 4 = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6 + 4[/tex]
Therefore, the equation is: y = -3/4x +10.

1) A golf store pays its wholesaler $40 for a certain club, and then sells it to
a golfer for $75. What is the markup rate?
The markup rate will be 87.5%.
Amount paid to wholesaler = $40
Amount that the good was sold = $75
Markup = $75 - $40 = $35
Markup percentage will be:
Markup/Cost price × 100
= (35/40) × 100
= 0.875 × 100
= 87.5%

2+2=4 and more is 2x4 it is
Answer:
Step-by-step explanation:
You can view 3x3 as 3+3+3. 3x4 is 3+3+3+3. 3x4 is also 4+4+4. And so forth.
So, you can see how 3+3 is the same as 3x2.
Hopefully, you can also see that 2x2 is 2+2 for the same reason. It becomes trivial.

Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes. Barry bought 1 dozen eggs and 10 pounds of potatoes, while Charles purchased 2 dozen eggs and 2 pounds of potatoes. If Adam’s bill was $38.25, Barry’s $36.50 and Charles’ $17.20, how much did a dozen eggs, a wheel of cheese and a pound of potatoes cost?
Answer:
Dozen eggs = $5.5
Wheel of cheese = $6.25
Pound of potatoes = $3.1
Step-by-step explanation:
Let the cost
Dozen of egg = x
Wheel of cheese = y
Pound of potato = z
We will form linear equations using the information given in the question
Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes
3x + y + 5z = 38.25 ................(1)
Barry bought 1 dozen eggs and 10 pounds of potatoes
x + 10z = 36.50 ............(2)
Charles purchased 2 dozen eggs and 2 pounds of potatoes
2x + 2z = 17.20 .................(3)
solving 2 and 3
x = $5.5 and z = $3.1
substitute these values in equation 1
we get
y = $6.25
The cost
Dozen eggs = $5.5
Wheel of cheese = $6.25
Pound of potatoes = $3.1
Zoey wants to use her iPad throughout a 6-hour flight. Upon takeoff, she uses the iPad for 2 hours and notices that the battery dropped by 25%, from 100% to 75%. How many total hours can Zoey expect from the iPad on a full battery charge?
Answer:
6 hours more
Step-by-step explanation
When Zoey started the flight the battery was 100%, then it dropped to 75% in 2 hours. So each 25% will last 2 hours and there is 75% remaining which if you divide by 3 it will give 1. And each 25% will last 6 more hours until the battery dies.

Julie's parents' 25th anniversary is in 2 years. She'd like to give her parents a vacation package for their anniversary. She anticipates the vacation package will cost her $2000. An account at her bank pays 5% per year compounded monthly. How much does she need to deposit today in this account, so that she can buy the package deal for her parents' anniversary?
a) Simple Interest
b) Future Value with compound interest
c) Future Value with simple interest
d) Effective Rate
e) Present Value with compound interest
Answer:
e) Present Value with compound interest
Step-by-step explanation:
in order to determine how much money does Julie need to deposit we have to use the present value formula with compound interest:
present value = future value / (1 + i/12)ⁿ
future value = $2,000i/12 = 5%/12 = 0.4167%n = 24$2,000 = present value x (1 + 0.4167%)²⁴
present value = $2,000 / (1 + 0.4167%)ⁿ = $1,810.05
you can also calculate it using the future value formula, but you will end with the present value formula:
future value = present value x (1 + i/12)ⁿ
present value = future value / (1 + i/12)ⁿ ⇒ you are adding 1 more step
you could also calculate it using the present value formula and the effective annual rate:
effective rate = (1 + 0.05/12)¹² - 1 = 5.1162%
present value = $2,000 / (1 + 5.1162)² = $1,810.05 ⇒ but again you are just adding more steps into the process

2/5 divided by 2 1/10
Answer:
4/21
Step-by-step explanation:
first you need to make them both fractions, not mixed numbers. so it would be 2/5 divided by 21/10. then you flip the second number so you can multiply it : 2/5 * 10/21. 5 and 10 are divisible by 5 so you can cross 5 out and make a 1 and cross 10 out and make a 2: 2/1 * 2/21. then multiply and you get 4/21!
