Kim's furniture store is offering a 30% discount on all its armchairs. Using a proportion, find the discount of the price of an armchair that originally cost $266.00.
Answer:
The discount is $79.80
Step-by-step explanation:
We need to solve this using proportions. We take the percent out of 100 on one side of the ratio and the discount over the total price on the other.
30 discount
----- = ----------
100 266
30* 266 = 100 * discount
7980=100 discount
Divide each side by 100
7980/100 = discount
79.80 = discount
a company uses paper cups shaped like cones for its water cooler. each cup has a height of 9cm, and the base has a diameter of 6 cm. the cooler had 12,717 cm to the third power of water in it. how many cups can be filled from the cooler?
use 3.14, do not round answer
Answer:
We can fill 150 paper cup cones.
Step-by-step explanation:
Volume of a cone is
V = 1/3 pi * r^2 *h
The volume of one cone is
pi = 3.14
r = d/2 = 6/2 =3
h=9
Substitute what we know
V = 1/3 * (3.14) * (3^2) * (9)
= 27* 3.14
= 84.78 cm^3
The water cooler has 12717 cm^3 water
Divide the water by the volume of the paper cup cone and we will know how many paper cup cones we can fill, assuming we fill them completely.
12717/ 84.78 = 150
We can fill 150 paper cup cones.
The volume of one cone-shaped paper cup is 84.78 cm³. With 12,717 cm³ of water in the cooler, approximately 150 cups can be filled.
To find out how many paper cups can be filled from the water cooler, we first need to calculate the volume of one paper cup. Given that the cup is shaped like a cone with a height of 9 cm and a base diameter of 6 cm, we can find the volume using the formula for the volume of a cone, which is V = (1/3)\u03c0r^2h, where V is the volume, r is the radius of the base, and h is the height of the cone.
The radius of the base is half the diameter, so r = 3 cm. Plugging in the values into the formula, we get: V = (1/3)*3.14*(3²)*9.
Calculating this, we get V \<= 84.78 cm³ per cup. Now, to determine how many cups can be filled from the cooler containing 12,717 cm³ of water, we divide the total amount of water in the cooler by the volume of one cup:
Number of cups = 12,717 cm³ / 84.78 cm³.
This gives us approximately 150 cups that can be filled from the water cooler.

A moving van rents for $29.95 a day plus $.12/mi.Mmi.Ms Smiths bill for a two day rental was $70.46. how many miles did she drive
Answer:
She drove 88 miles
Step-by-step explanation:
Total cost = fee per day + cost per mile * miles driven
We know the total cost was 70.46
The fee per day was 29.95 *2 =59.90. She kept the van 2 days.
The cost per mile was .12
Substitute in what we know
70.46 = 59.90 +.12 m
Subtract 59.90 from each side
70.46-59.90 = 59.90-59.90 +.12 m where m is the miles driven
10.56 = .12m
Divide each side by .12
10.56/.12 = .12m/.12
88=m

what is the slope of the line i ready
The slope of the given line, determined from the graph and the point-slope form, is -0.5.
The slope of a line is a measure of its steepness. To determine the slope from a graph, you can use the point-slope form and the slope-intercept form of a linear equation.
Given a graph with points (0,1) and (0.5,0), you can calculate the slope as follows:
Use the point-slope form of a linear equation:
(y - y1) / (x - x1) = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are points on the line.
Plug in the coordinates of the given points:
(y - 1) / (x - 0) = (0 - 1) / (0.5 - 0)
Simplify:
(y - 1) / x = -1 / 0.5
Further simplify:
2(y - 1) = -x
Rearrange to isolate y:
2y - 2 = -x
2y = -x + 2
y = (-1/2)x + 1
Compare this equation to the slope-intercept form, y = mx + c. In this case, the slope (m) is -1/2, which is equivalent to -0.5.

In its first year of business, Arlo’s Dry Cleaners had a closing balance of –$1,500. The second year it lost an additional $1,200. What is the closing balance at the end of year two?
Answer:
-2700 dollars
Step-by-step explanation:
The first year we have a loss of 1500 dollars. On the balance sheet we write -1500, with the negative indicating loss. Some accounting practices will use parenthesis to mean loss, so you might see it as (1500). But in this problem, we'll use negative signs for loss.
The second year is loss of 1200. Add up the two losses (the positive versions of each) to get 1500+1200 = 2700. Then make the result negative. Taking one loss and adding more loss to it means your loss has gotten bigger. So that's why the closing balance at the end of year 2 is -2700 dollars, which is a loss of 2700 dollars.

A six-sided die with sides labeled 1 through 6 will be rolled once. Each number is equally likely to be rolled.
What is the probability of rolling a number greater than 2?
Write your answer as a fraction.
Answer:
2/3
Step-by-step explanation:
Given that a six sided die with sides labelled with numbers 1,2,3,4,5 and 6 is rolled once.
Since die is said to be equally likely for each number, die is unbiased
P(1) = P(2)=...=P(6) = 1/6
For a number greater than 2, we must not include 2 and hence numbers can be 3 or 4 or 5 or 6
Probability of rolling a number >2 = Probability of rolling 3 or 4 or 5 or 6
= P(3)+P(4)+P(5)+P(6)
= 1/6+1/6+1/6+1/6
=4/6
=2/3
Required probability = 2/3
The probability of rolling a number greater than 2 on a six-sided die is 2/3. This is because there are 4 numbers greater than 2 on the die and the total number of possible outcomes when the die is rolled is 6.
Explanation:The subject of this question is probability, a topic in mathematics. To solve this problem, we need to first understand the total possible outcomes when rolling a six-sided die. The outcomes are the numbers 1 through 6, so we have 6 possible outcomes.
To find the probability of rolling a number greater than 2, we need to determine how many outcomes match this condition. The numbers greater than 2 on a six-sided die are 3, 4, 5, and 6. So, there are 4 favorable outcomes.
Probability is calculated by dividing the number of favorable outcomes by the total number of outcomes. So, the probability of rolling a number greater than 2 on a six-sided die is 4/6, which simplifies to 2/3.

What is the answer to number 10?
Answer:
E 8
Step-by-step explanation:
y = w x^2
If we double w and x, replae w with 2w and x with 2x and solve for y
y = (2w) * (2x)^2
Do the powers first
y = 2w * (4x^2)
y = 8wx^2
Y is now increased by a factor of 8
Answer:
Y will be multiplied by 8.
Right option is (E)
Step-by-step explanation:
We have, y = wx²
y is not 0.
If w and x are doubled
That means,
w' = 2w and x' = 2x
So , y' =w'x'²
or y' = (2w)×(2x)²
or y' = 2w×4x²
or y' = 8wx²
Since y = wx²
so y' = 8y.
That means if we double the w and x then y will be multiplied by 8.

Answer:
y = 20x + 40
Step-by-step explanation:
Given that the rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental.
That means fixed one time cost is $40 which doesn't changes with time.
If number of days is represented by "x" then rental cost for "x" days will be 20 times x or just 20x.
So the final cost will be sum of fixed cost and the rental cost per day which is:
20x+40
Now if "y" represents total rental cost over time then final cost equation can be written as:
y = 20x + 40
Hence final answer is y = 20x + 40y = 20x + 40.
Answer:The answer is Y=20x+40
A phone company offers two monthly plans. Plan A costs $24 plus an additional $0.09 for each minute of calls. Plan B costs $20 plus an additional $0.14 for each minute of calls. For what amount of calling do the plans equal the same cost? What is the cost when the two plans cost the same?
x = number of minutes used, y = total cost in dollars
Plan A: y = 0.09x + 24
Plan B: y = 0.14x + 20
Equate the two right hand side (RHS) expressions and solve for x
0.14x + 20 = 0.09x + 24
0.14x - 0.09x = 24 - 20
0.05x = 4
x = 4/0.05
x = 80
The two plans will cost the same amount of money if you use up 80 minutes
Plug in x = 80 into either equation to find y
y = 0.09*x + 24
y = 0.09*80 + 24
y = 31.20
or
y = 0.14*x + 20
y = 0.14*80 + 20
y = 31.20
So both plans will cost $31.20 if you use up 80 minutes
A wooden board is leaning against a building. The base of the board is 4 feet from the base of the building, and the base of the board forms a 65 degree angle with the ground.
What is the length of the wooden board?
_____ft
Answer:
The length of wooden board = 9.4648 feet.
Step-by-step explanation:
The wooden board makes a Right triangle with the building in which we have wooden board as hypotenuse, building as opposite side, and ground as adjacent side, the angle of elevation is 65 degrees.
Given adjacent side = 4 feet and elevation angle = 65 degrees.
We can use cosine formula in right triangle as follows:-
Cos(65°) = Adjacent / Hypotenuse
cos(65°) = 4 / Hypotenuse
Hypotenuse = 4 / cos(65°)
Hypotenuse = 9.464806333 feet.
Hence, the length of wooden board = 9.4648 feet.
Final answer:
To find the length of the wooden board which forms a 65-degree angle with the ground and has its base 4 feet from the building, use the cosine function to calculate the hypotenuse of the right triangle formed. The length of the board is approximately 9.06 feet.
Explanation:
To find the length of the wooden board leaning against a building, we can use trigonometry. Since the base of the board forms a 65-degree angle with the ground, and the distance from the base of the building to the base of the board is 4 feet, we have a right-angled triangle where we know the angle and the adjacent side.
Step-by-step solution:
Identify the right triangle formed by the board, the ground, and the wall of the building.
Use the cosine function which relates the adjacent side and hypotenuse in a right triangle. The cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse (cos(θ) = adjacent/hypotenuse).
Rearrange the formula to solve for the hypotenuse: hypotenuse = adjacent/cos(θ).
Plug in the values: hypotenuse = 4 ft / cos(65°).
Calculate the length using a calculator: hypotenuse ≈ 4 ft / cos(65°) ≈ 9.06 ft.
The length of the wooden board is approximately 9.06 feet.
