select all that apply
A. 0.20x
B.0.80x
C.x-0.20
D.x-0.80x
E.x(0.2+1.00)
F. x(1.00-0.20)
Answer:
B. 0.80x
F. x(1.00-0.20)
Step-by-step explanation:
The Formula for Selling Price when you have percent markdown is;
Selling price = (1 - percentage mark down)× Original price
From the question:
Selling price= Cost of the shirt(excluding tax)
Original price = x
Percentage markdown = 20%
= 0.20
Hence,
Cost of the shirt(excluding tax)
= (1 - 20%)x
= (1 - 0.20)x
= 0.80x
Option B and F is the correct option
Janice put $5823.00 into a savings account that pays 2.25% interest.If she leaves that money in the account for 4 years,how much will the balence of her account be?
Given:
Principal value = $5823.00
Rate of interest = 2.25%
Time = 4 years
To find:
The amount in the account after 4 years.
Solution:
The formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
where, P is principal, r is rate of interest and t is time period.
Putting P=5823, r=2.25 and t=4 in the above formula.
[tex]A=5823\left(1+\dfrac{2.25}{100}\right)^4[/tex]
[tex]A=5823\left(1+0.0225\right)^4[/tex]
[tex]A=5823\left(1.0225\right)^4[/tex]
[tex]A=5823(1.0930833)[/tex]
[tex]A=6365.0240559[/tex]
[tex]A\approx 6365.024[/tex]
Therefore, the amount in the according after 4 years is about $6365.024.
The equation c = 2.95g represents the proportional relationship between the cost of gasoline and the amount purchased on a given day. In the equation, c represents the cost in dollars, and g represents how many gallons of gas were purchased. What is the constant of proportionality for this relationship?
Answer:
2.5
Step-by-step explanation:
Given the expression c = 2.95g
since c represents cost
g represents how many gallons of gas were purchase
the terms that relates the cost to the numbers of gallons purchased is
2.5 which is equally the constant of proportionality
Therefore the constant of proportionality is 2.5

Thomas went to the store to buy video games for $13.50 each and controllers that cost $55 each. Write and equation where c represents the total cost, g is the number of games he bought, and p is the number of controllers he bought.
Answer:
c = 13.50g + 55p
Step-by-step explanation:
You multiply the cost of the item by the amount you bought.
An equation for the total cost of video games and controllers is c = 13.50g + 55p.
Given that, Thomas went to the store to buy video games for $13.50 each and controllers that cost $55 each.
We need to write an equation where c represents the total cost, g is the number of games he bought, and p is the number of controllers he bought.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, the total cost of video games=13.50g
The total cost of controllers=55p
Total cost =c = 13.50g + 55p
Therefore, an equation for the total cost of video games and controllers is c = 13.50g + 55p.

y=-1/4x+7 y=4x-4
is this a perpendicular or parallel line?
Answer:
It's perpendicular
Step-by-step explanation:
All you need to do to solve these problems is look at the slope, so the x in each equation
If it's parallel the slope will be the exact same (ex. y = 2x + 4 and y = 2x - 8)
If the equation is perpendicular the slopes will be Opposite Reciprocal so they have opposite signs (pos./neg.) and will be the reciprocal of each other (ex. 5 = 1/5)
So a perpendicular line will look like this- y = -4x + 2 and y = 1/4x - 2
The y-intercept will never matter for this question. Hope I could help!

4. Rusty's hair grows at the rate of 2/4 inch per month. a. How many months will it take Rusty's hair to grow 7/8 inch? b. Explain your answer using words, and show your work using division of fractions.
Answer:
x = 1 month 3 days
Step-by-step explanation:
Given that,
Per month growth of Rusty's hair = 2/4
We need to find in how many months will it take Rusty's hair to grow 7/8 inch.
1 month = 2/4
In x months = 7/8 inches
Let it grow 7/8 inch in x months.
[tex]\dfrac{\dfrac{2}{4}}{\dfrac{7}{8}}=\dfrac{1}x\\\\\dfrac{1}{x}=\dfrac{2}{4}\times \dfrac{8}{7}\\\\x=\dfrac{7}{4}\ \text{months}\\\\x=1\ \text{month}\ 3\ \text{days}[/tex]
So, it will take 1 month 3 days to grow 7/8 inches.
Answer:
x = 1 month 3 days
Step-by-step explanation:
Given that,
Per month growth of Rusty's hair = 2/4
We need to find in how many months will it take Rusty's hair to grow 7/8 inch.
1 month = 2/4
In x months = 7/8 inches
Let it grow 7/8 inch in x months.
So, it will take 1 month 3 days to grow 7/8 inches.

Lerna's Hydra is a mythological character that appears in some stories such as the 12 Tasks of Hercules. The Hydra was a one-headed monster but when it is cut off, 2 more heads grow in its place. If a hero tried to conquer it by cutting off all of its heads every day, how many heads would the Hydra have on the third day? And at the end of 10 days of trying to kill it?
Answer:
a. 8 heads. b. 1024 heads.
Step-by-step explanation:
a. How many heads would the Hydra have on the third day?
Since the Hydra's head doubles for every initial head that is cut off on each day, the number of heads the hydra has after each day is 2ⁿ where n = number of days. Now, the head increase of the Hydra form a geometric sequence with the first term as 2 since we initially had one head and was cut off to produce 2 heads. On the second day, two heads are cut off to produce four which is 2² and so on.
So, on the third day, we have 2³ heads = 8 heads.
b. And at the end of 10 days of trying to kill it?
At the end of 10 days we have n = 10 in 2ⁿ. So, 2¹⁰ = 1024 heads.
So, at the end of 10 days, the Hydra has 1024 heads.
