Dena is buying wallpaper. It costs $8.79 per meter. She needs 120 feet. How much will the wallpaper cost? Round to the nearest half dollar.
Answers
Answer:
321.50 dollars.
Step-by-step explanation:
Dena is buying wallpaper. It costs $8.79 per meter. She needs 120 feet. How much will the wallpaper cost? Round to the nearest half dollar.
This is a tricky math problem that requires some conversions and calculations. First, we need to convert feet to meters, because Dena lives in a country that uses the metric system. According to the search results , one foot is equal to 0.3048 meters. So, 120 feet is equal to 120 x 0.3048 = 36.576 meters.
Next, we need to multiply the length of the wallpaper by the price per meter to get the total cost. The total cost is 36.576 x 8.79 = $321.38.
Finally, we need to round the total cost to the nearest half dollar. This means we need to look at the cents part of the cost and see if it is closer to 0, 50 or 100. In this case, 38 cents is closer to 50 than to 0 or 100, so we round up the cost to $321.50.
Therefore, Dena will have to pay $321.50 for the wallpaper. That's a lot of money for some paper that will probably peel off in a few years! Maybe she should consider painting her walls instead.

Step-by-step explanation:
There are two major categories of variables in data measurement: Discrete and Continuous variables
A Discrete variable is a type variable that can take on a distinct number, obtained by counting, and there is a limit to the value that that variable can take on. An example is the number of students in a class. This can be 10, or 20 or 25, etc. There cannot be 12.8 students or 13.1 students. Hence this kind of variable is a discrete variable.
A Continuous variable is one that is measured and not counted. they have an infinite possibility within a range in a scale of measurement. An example is; the height of trees in meters. The possibilities can be 3.6m, 4.08m, 5m, 1.9m, etc. There is no distinct number, but a possibility of ranges.

This month my metro water services bill was $36.34 and my Madison Suburban Utilty District bill was $26.03. My total water bill was $
Answers
Total water bill for the month is $62.37.
It seems that you may have accidentally left out the total amount of your water bill.
The total amount by simply adding the amounts of the individual bills together:
Total water bill =\($36.34 + $26.03\)
= \($62.37\)
You have not provided enough information to determine your total water bill.
You have only given the amounts of your individual bills from Metro Water Services and Madison Suburban Utility District.
To find your total water bill, you simply need to add the two bills together.
So, the total amount you owe for water this month would be:
Total water bill = \($36.34 + $26.03\)
= \($62.37\)
It appears that you may have forgotten to include the full amount of your water bill by accident.
Simple addition of the separate bill amounts yields the following sum:
Water bill total = \($36.34 + $26.03\)
= \($62.37\)
Your total water bill cannot be calculated because not enough information has been given.
Only the amounts of your individual Metro Water Services and Madison Suburban Utility District bills have been provided.
You just need to combine the two invoices together to get your total water bill.
As a result, this month's total water bill for you would be:
Water bill total = \($36.34 + $26.03\)
= \($62.37\)

She walked neighbor's dog 4 times.
Step-by-step explanation:
It is given that:
Peri earned $27 for walking the dogs 3 times.
Unit rate = \(\frac{27}{3}\)
Unit rate = $9 per dog
Now,
Peri worked at the same rate and earned $36.
Unit rate = \(\frac{Total\ earning}{Dogs\ walked}\)
\(9 = \frac{36}{d}\)
d= 36/9
d = 4
Therefore,

It costs $1,400 to manufacture 100 designer shoes, and $4,100 to manufacture 400 designer shoes. If x represents the number of shoes, and y is the costs,
find the cost equation
What is the cost to manufacture 150 shoes
If the product sells for $19 per item; find the Revenue Function
Determine the number of items needed to break even.
Answers
Answer:
To find the cost equation, we can use the two data points given:
(100, 1400) and (400, 4100)
We can use the point-slope form of a linear equation, where the slope is the change in cost over the change in quantity:
slope = (4100 - 1400) / (400 - 100) = 2700 / 300 = 9
Using the point-slope form with the first data point:
y - 1400 = 9(x - 100)
y - 1400 = 9x - 900
y = 9x + 500
So the cost equation is y = 9x + 500.
To find the cost to manufacture 150 shoes, we can plug in x = 150 into the cost equation:
y = 9(150) + 500 = 1850
So the cost to manufacture 150 shoes is $1850.
To find the revenue function, we multiply the number of shoes sold by the price per shoe:
Revenue = price x quantity = 19x
To determine the number of items needed to break even, we need to find the quantity where revenue equals cost. Let C(x) be the cost function and R(x) be the revenue function. The break-even point occurs when:
C(x) = R(x)
9x + 500 = 19x
500 = 10x
x = 50
So the company needs to sell 50 designer shoes to break even.
Step-by-step explanation:
Answer:
Cost equation: y = 9x + 500
It costs $1,850 to manufacture 150 shoes.
Revenue function: R(x) = 19x
The number of items that need to be sold to break even is 50.
Step-by-step explanation:
Definition of variables
x is the number of designer shoes manufactured.y is the cost (in dollars) to manufacture the designer shoes.If it costs $1,400 to manufacture 100 designer shoes:
x = 100 when y = 1400.If it costs $4,100 to manufacture 400 designer shoes:
x = 400 when y = 4100.Assuming the relationship between the number of shoes and the cost to manufacture them is linear, the slope of the equation of the line the models the relationship can be found by dividing the change in y-values by the change in x-values of the two data points:
\(\implies \sf Slope\;(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4100-1400}{400-100}=9\)
Substitute the found slope and one of the points into the point-slope form of a linear equation to create an equation that gives the total cost to manufacture the shoes in terms of the number of shoes (x):
\(\implies \sf y-y_1=m(x-x_1)\)
\(\implies \sf y-1400=9(x-100)\)
\(\implies \sf y-1400=9x-900\)
\(\implies \sf y=9x+500\)
Therefore, the cost equation is y = 9x + 500.
To calculate the cost to manufacture 150 shoes, substitute x = 150 into the cost equation:
\(\begin{aligned}\implies \sf y&=\sf 9(150)+500\\&= \sf 1350+500\\&= \sf 1850\end{aligned}\)
Therefore, it costs $1,850 to manufacture 150 shoes.
The revenue is the income a company generates before any expenses are subtracted. Therefore, the revenue function is simply the selling price of the item multiplied by the number of items sold.
Given the product sells for $19 per item, the revenue function is:
\(\implies \sf R(x)=19x\)
The break even point is the point at which the total revenue equals the total cost, so there is neither profit nor loss.
To determine the number of items that should be sold to break even, equate the cost equation and the revenue function and solve for x.
\(\begin{aligned}\sf R(x)&=\sf y\\\implies \sf19x&=\sf 9x+500\\\sf 10x&=500\\\sf x&=50\end{aligned}\)
Therefore, the number of items that need to be sold to break even is 50.

426 ➗ 2 using partial quotients
Answers
Answer: 212
Step-by-step explanation:
To perform the division of 426 ÷ 2 using partial quotients, we can divide 426 into two parts, one part being close to the divisor, and the other part being the remainder.
We start by dividing 426 by 2 to get an estimate of the quotient. The closest multiple of 2 to 426 is 424, so we can write:
424 ÷ 2 = 212
Next, we subtract 424 from 426 to find the remainder:
426 - 424 = 2
We write the quotient (212) next to the dividend (426) and bring down the next digit (0) to form a new dividend of 20:
426 | 20
212
Repeat steps 1 to 3, dividing 20 by 2, to get:
20 ÷ 2 = 10
So, the final answer is:
426 ÷ 2 = 212 with a remainder of 0, or simply
426 ÷ 2 = 212.

Answer:
The correct answer is:
(a) 0.0784
(b) 0.0588

n (ace or king) = 8
Number of red,
n (red) = 26
Number of club,
n (club) = 13
Number or jack,
n (jack) = 4
(a)
Probability of 1st ace or king and 2nd in red will be:
⇒ \(P(ist \ ace \ or \ king \ and \ 2nd \ red) = \frac{8}{52}\times\frac{26}{51}\)
⇒ \(=0.0784\)
(b)
Probability of both clubs will be:
⇒ \(P(clubs) =\frac{13C_2}{52C_2}\)

\(\frac{x}{sin76}\) = \(\frac{19}{sin34}\) ( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x = \(\frac{19sin76}{sin34}\) ≈ 33.0 ( to the nearest tenth )
Answer:
