Hi There!
Solution + Answer:
2 gallons of milk: 3.29 * 2 = $6.58
4 gallons of ice-cream: 3.59 * 4 = $14.36
5 pounds of strawberries: 0.72 * 5 = $3.60
Total price before tax: 6.58 + 14.36 + 3.60 = $24.54
Tax: 24.54 * 0.0375 = $0.92025
Total price after tax: 24.54 + 0.92025 = $25.46025
Round: 25.46025 = $25.46
Hope This Helps :)
According to the question,
2 gallons of milk,
= [tex]3.29\times 2[/tex]
= [tex]6.58[/tex] ($)
4 gallons of ice-cream,
= [tex]3.59\times 4[/tex]
= [tex]14.36[/tex] ($)
5 pounds of strawberries,
= [tex]0.72\times 5[/tex]
= [tex]3.60[/tex] ($)
Now,
The total price before tax will be:
= [tex]6.58+14.36+3.60[/tex]
= [tex]24.54[/tex] ($)
The tax will be:
= [tex]24.54\times 0.0375[/tex]
= [tex]0.92025[/tex] ($)
hence
The total price after tax will be:
= [tex]24.54+0.92025[/tex]
= [tex]25.46025[/tex]
or,
= [tex]25.46[/tex] ($)

Adia plans to wallpaper her bedroom. The measurements are 10’ by 12’ with 8’ ceilings.
Part 2: If each single roll of wallpaper covers 72 square feet, how many single rolls of wallpaper will Adia need for her project?
Answer: _ single rolls (type the number only)
-------------------------------------------------------------------------------------
Adia plans to wallpaper her bedroom. The measurements are 10’ by 12’ with 8’ ceilings.
Part 3: If each single roll of wallpaper covers 72 square feet, how many double rolls of wallpaper will Adia need for her project?
Answer: _ double rolls (type the number only)
Answer:
5 single rolls or 3 double rolls.
Step-by-step explanation:
Ignoring doors and windows, we need to find the lateral surface ares. We are not papering the ceiling or floor.
The lateral surface areas = P*h
= 2(l+w) * h
= 2(10+12) * 8
= 2(22)*8
=352 ft^2
A single roll covers 72 ft^2 so we divide the number of ft^2 that we need (352^2) by the amount of a single roll
352/72 =4.88888(repeating)
Rounding up since we need to buy in full rolls.
We will need 5 rolls
Assuming a double roll will cover twice that of a single roll
2*72 = 144 ft^2
Take 572/144 =2.4444444
Rounding up since we need to buy in full rolls.
We will need to buy 3 double rolls
Adia will need 5 single rolls or 3 double rolls of wallpaper to cover her 10' by 12' bedroom with 8' ceilings.
Adia needs to calculate the amount of wallpaper needed to cover the walls of her bedroom. To find the total wall area, we calculate the perimeter of the room and multiply it by the ceiling height. The perimeter is two times the length (12 feet) plus two times the width (10 feet), giving us 44 feet. Multiplying the perimeter by the ceiling height (8 feet) gives us the total wall area: 44 feet × 8 feet = 352 square feet.
Since each single roll covers 72 square feet, dividing the total wall area by the coverage of one roll gives us the number of rolls needed: 352 square feet / 72 square feet/roll = 4.89, which means Adia will need 5 single rolls of wallpaper.
For double rolls, we need to consider that each double roll is equivalent to two single rolls.
Therefore, we divide the number of single rolls needed by 2 to get the number of double rolls: 5 single rolls / 2 = 2.5, which means Adia will need 3 double rolls (since she can't purchase half a roll, she'll have to round up).

the power in an electrical circuit is given by the equation p= /2 r, where / is the current flowing through the circuit. what is the current in a circuit that has resistance of 100 ohms and a power of 15 watts?
A. 0.15 amps
B. 0.39 amps
C. 6.7 amps
D.2.6 amps
Answer:
Actually, the equation is
power (in Watts) = I² * r
I - current in amps and r - resistance in watts
Solving this for the current (I)
I = square root (power / resistance)
I = square root (15 / 100)
I = square root (.15)
I = 0.3872983346 amps
answer is B
Step-by-step explanation:
The current in the circuit is approximately 0.39 amperes, which is option B.
The power in an electrical circuit can be calculated using the formula:
P = I^2 * R
Where:
P = Power (in watts)
I = Current (in amperes)
R = Resistance (in ohms)
In your case, you have:
P = 15 watts
R = 100 ohms
You want to find the current (I), so rearrange the formula to solve for I:
I = sqrt(P / R)
I = sqrt(15 watts / 100 ohms)
I = sqrt(0.15 A^2)
I = 0.39 A (approximately)
So, the current in the circuit is approximately 0.39 amperes, which is option B.

Write a function rule for the data in the table. Determine if it's a direct variation, inverse variation or neither. Last, determine the value of x if y=10.
Answer: [tex]\bold{y=\dfrac{24}{x}}[/tex] ; indirect variation ; x = 2.4
Step-by-step explanation:
direct variation is when: [tex]\dfrac{y}{x}=k[/tex] ; where k is the constant rate
indirect variation is when: xy = k ; where k is the constant rate
In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation: [tex]y = \dfrac{24}{x}[/tex]
since k = 24, then input y = 10 and k = 24 into the equation above:
[tex]10 = \dfrac{24}{x}[/tex]
[tex]10x = 24[/tex]
[tex]x = \dfrac{24}{10}[/tex]

Thirty-six of the students in the school choir like to sing solos. These 36 students make up 24% of the choir. How many students are in the choir?
Answer:
150
Step-by-step explanation:
We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other.
[tex]\frac{24}{100}=\frac{36}{y}[/tex]
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
24y=100(36)
24y=3600
y=150.
There are 150 students in the choir.
The amount of time t (in hours) it takes to complete a certain job varies inversely with the number of workers, w. The constant of variation is 28. Find the time it takes to complete the job when the number of workers is 16.
Answer:
1.75 h
Step-by-step explanation:
t = k/w
k = 28
t = 28/w
If w = 16,
t = 28/16
t = 1.75 h
It will take 16 workers 1.75 h to complete the job.
The length of a rectangle is 7 feet. If the perimeter is 42 feet, what is the width of the rectangle
The perimeter of a rectangle is found by multiplying the length by 2 and then adding that to the width multiplied by 2.
The length is 7, multiplied by 2 = 7x2 = 14.
Subtract that from the total perimeter:
42 - 14 = 28
The length of the 2 widths is equal to 28, to find the length of 1 width, divide that by 2:
Width = 28 / 2 = 14
The width is 14 feet.

b. circus horses eat about 250 pounds of horse food per week. about how many pounds of food does a circus horse eat each day? explain. (hint: 1 week = 7 days)
Answer :
(a) The number of rows need will be, 57 rows.
(b) The amount in pounds of food a circus horse eat each day is, 35.71 pounds.
Step-by-step explanation :
Part A:
As we are given that the there are 9 seats in each row that means 9 people can sit in each row.
Now we have to determine the number of rows will need to be set up if 513 people are expected to attend the show.
As, 9 people can sit in 1 row
So, 513 people can sit in [tex]\frac{513}{9}=57[/tex] row
Thus, the number of rows need will be, 57 rows.
Yes, the rows be divided into a number of equal sections as, 3 rows would be 19 sections or, 19 rows would be 3 sections.
Part B:
As we are given that circus horses eat about 250 pounds of horse food per week. Now we have to determine the amount in pounds of food does a circus horse eat each day.
Given : 1 week = 7 days
As, in 1 week the circus horses eat about 250 pounds of horse food
or, in 7 days the circus horses eat about 250 pounds of horse food
So, in 1 day the circus horses eat about [tex]\frac{1day}{7day}{\times 250=35.71[/tex] pounds of horse food
Thus, the amount in pounds of food a circus horse eat each day is, 35.71 pounds.

A line crosses the y-axis at (0,4) and has a slope of -2. Find an equation for this line. A) y = 2x + 4 Eliminate B) y = -2x + 4 C) y = -2x - 4 D) y = -4x + 2
Answer:
We have the equation y - 4 = (-2)( x - 0 );
Then, y - 4 = -2x;
Finally, y = -2x + 4;
The correct answer is B) y = -2x + 4;
Step-by-step explanation:
The equation for the line with a slope of -2 and crossing the y-axis at (0,4) is y = -2x + 4.
To find an equation for a line that crosses the y-axis at (0,4) with a slope of -2, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. Since we are given that the slope (m) is -2 and the y-intercept (b) is 4, the equation of the line is y = -2x + 4.
Why might where you live be a factor in determining your utility costs?
Answer:
Well some places are more expensive. This will effect the prices of utilities because some places have a higher expense of living because of the lack of certain materials or because of the desirable location. For example, although living in Hawaii was beautiful, it was extremely expensive for everyday items because most things needed to be shipped and because of constant tourism.
The factor for dependency of Utility Cost shown below.
What is Utility Cost?The cost of using utilities like power, water, waste disposal, heating, and sewage is known as a utilities expense. During the reporting period, the costs are incurred, computed, and accumulated for, or a payment is made.
Given:
Due to climate and fluctuating utility prices, location might affect your utility expenditures. The expense of heating would be higher in an extremely cold climate than in a warmer one.
Certain locations are more pricey. The cost of utilities will be impacted because some regions have a greater cost of living due to a shortage of specific materials or a desirable location.
For instance, even though Hawaii was a wonderful place to live, the cost of basic necessities was very high due to the frequent tourism and the fact that the majority of goods had to be shipped.

What is the effect on the graph of the function f(x) = x when f(x) is replaced with −1/2f(x)?
A) vertical reflection over x-axis and vertical stretch
B) vertical reflection over x-axis and vertical compression
C) horizontal reflection over y-axis and horizontal stretch
D) horizontal reflection over y-axis and horizontal compression
When the function f(x) is replaced with -1/2f(x), it results in vertical reflection over x-axis and vertical compression of the graph.
Explanation:When the function f(x) is replaced with -1/2f(x), it means that the values of the original function are multiplied by -1/2. This has two effects on the graph of the function:
Vertical reflection over the x-axis: The positive values of f(x) become negative and vice versa. This flips the graph of the function vertically.Vertical stretch: The values of f(x) are multiplied by -1/2, which compresses the graph vertically. The new graph will be half as tall as the original graph.Therefore, the correct answer is B) vertical reflection over x-axis and vertical compression.

Identify the domain of the graphed function.
Answer:
(-4,-2) U (-2,4]
Step-by-step explanation:
Domain is the set of x values for which the function is defined.
We look at the x values on the graph
the graph starts at -4 and we have a hole at x=-4
For a hole we use parenthesis
Graph starts at -4 and ends at -2. Both -4 and -2 have hole, so we use parenthesis.
So interval is (-4,-2)
From -2 to 4 , there is no hole or break in between. the graph is continuous from -2 to 4
so interval is (-2, 4]
combine both intervals
(-4,-2) U (-2,4]
Answer:
B. (-4,-2) (-2,4)

Find the zeros of the function f(x) = x2 + 5x + 6. A) y = 6 because the graph crosses the y-axis at 6. B) y = -0.25 because that is the minimum value of the graph. C) x = 2 and x= 3 because the graph crosses the x-axis at 2 and 3. D) x = -3 and x = -2 because the graph crosses the x-axis at -3 and -2.
Answer:
D.)
Step-by-step explanation:
The zero's are referencing when y=0, note that when y=0 they are talking about the x-intercepts. You can graph the function and see when the graph crosses the x-axis or solve for the x-values. I will solve it via factoring and so:
[tex]f(x)=x^2+5x+6[/tex]
Multiply the outer coefficients, in this case 1 and 6, and 1×6=6. Now let's think about all the factors of 6 we have: 6×1 and 2×3. Now is there a way that if we use any of these factors and add/subtract them they will return the middle term 5? Actually we can say 6-1=5 and 2+3=5. Let's try both.
First let's use 6 and -1 and so:
[tex]x^2+5x+6\\\\x^2+6x-x+6\\\\x(x+6)-1(x-6)[/tex]
Notice how we have (x+6) and (x-6), these factors do not match so this is incorrect.
Now let's try 2 and 3 and so:
[tex]x^2+5x+6\\\\x^2+3x+2x+6\\\\x(x+3)+2(x+3)\\\\(x+2)(x+3)[/tex]
Notice how the factors (x+3) matched up so this is a factor and so is (x+2), now to solve for the zero's let's make f(x)=0 and solve each factor separately:
Case 1:
[tex]f(x)=x+2\\\\0=x+2\\\\x=-2[/tex]
Case 2:
[tex]f(x)=x+3\\\\0=x+3\\\\x=-3[/tex]
So your zero's are when x=-2 and x=-3.
D.) x=-3 and x=-2 because the graph crosses the x-axis at -3 and -2.
