A store owner buys cell phones for $40 and marks up the price by 25%. What is the sale price of a phone?
Answer:
$50
Step-by-step explanation:
Price of the cell phone bought p = $40
% of markup in price = 25%
Selling price of the cell phone = p + (%)p
Selling price of the cell phone = P + (0.25)p
Selling price of the cell phone = p + 0.25p
Selling price of the cell phone = 1.25p
Selling price of the cell phone = 1.25 * $40
Selling price of the cell phone = $50

I = $60, P = $750, r = 4%, t = ?. Find the amount of time
Answer:
The time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
Step-by-step explanation:
Given
Interest I = $60Principle P = $750Interest rate r = 4% = 0.04To determine
Time period t = ?
Using the formula
I = Prt
t = I / Pr
substitute I = $60, P = $750 and r = 0.04 in the equation
t = 60 / ( 750 × 0.04 )
t = 2 years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot? Write your answer as a fraction or as a whole or a mixed number
Answer:
1/10 acres
Step-by-step explanation:
A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?
This is calculated as:
1 lot = 1 house
Hence:
9 house = 9/10 acres
1 house = x
Cross Multiply
9x = 9/10 acres
x = 9/10 ÷ 9
x = 9/10 × 1/9
x = 1/10 acres
Hence, the size of each lot when divided equally = 1/10 acres

4.3x+5x=16+7-(7)
9.3x=16
x= 1.72
give me a brainliest if possible. please.. tnx
Answer: 1.72.......
Step-by-step explanation: 4.3x + 7 + 5x = 16 + 7
=> 7 + (5x + 4.3x) = 16 + 7
7 + 9.3x = 23
9.3x = 23 - 7 [ 7 becomes -7 when transferred to RHS]
9.3x = 16
x = 16 /9.3 [ 9.3 becomes 1/9.3 when transferred to RHS]
x = 1.72......

John and Lauren are looking for a good neighborhood to raise their children. They want neighbors who
have kids and who are fellow rollerbladers as well. The couple surveys a random sample of residents in a
nice-looking neighborhood. Their results are shown below.
Matthew, Patrick, and Susan live in the neighborhood. Matthew rollerblades every Sunday. Patrick is a
computer programmer, but that's all we know about him. Susan is a stay-at-home mom.
Calculate the following probabilities based on the frequency table below.
Round to the nearest hundredth of a percent.

Answer:
Matthew does not have kids = 18%
Patrick has kids and does not Rollerblade = 4.84%
Susan Rollerblades = 93.18%
Step-by-step explanation:

3÷62 ≈ 0.0484 = 4.84%
41 ÷ 44 ≈ 0.9318 = 93.18%

in one year dog's weigh from 64 pounds to 80 pounds . by what percentage did the dog's weght increase
Answer:
15%
Step-by-step explanation:
First, let's find how many pounds the dog's weight increased by during the year.
80 - 64 = 16
Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).
[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%
Is there a proportional relationship between the number of pounds of apples and their cost? Is there a proportional relationship between the number of toppings on a pizza and its cost? Explain how you know.
The question is incomplete, the complete question is;
Based on the information in the table, is the cost of the apples proportional to the weight of apples?
Pound of apples:
2
3
4
5
Cost of apples:
$3.76
$5.64
$7.52
$9.40
2. Based on the information in the table, is the cost of the pizza proportional to the number of toppings?
Number of toppings:
2
3
4
5
Cost of pizza:
$11.99
$13.49
$14.99
$16.49
Answer:
See explanation
Step-by-step explanation:
Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.
We know that there is a proportional relationship when there is a linear increase or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.
In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.
Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

Write an equation for the statement. Then, solve the equation:
The volume of a can varies jointly as the height of the can and the square of its radius. A can with an 8 inch
height and 4 inch radius has a volume of 402.12 inches cubed. What is the volume of a can that has a 2 inch
radius and a 10 inch height?
PLZZ help
Answer:
V = 125.6 in³
Step-by-step explanation:
let V be volume, h the height and r the radius, then the equation relating the quantities is
V = khr² ← k is the constant of variation
To find k use the condition V = 402.12, h = 8, r = 4
402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )
3.14 = k [ note 3.14 is π )
V = 3.14hr² ← equation of variation [ V = πr²h ]
Given r = 2 and h = 10, then
V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

Answer:
(x³+2x²)/3 cm³Step-by-step explanation:
Find the diagram attached
Volume of a pyramid = 1/3 * Base area * height
Base area = x*x
Base area = x²
Height = x+ 2
Get the volume:
Volume of the pyramid = 1/3 * x² * x+2
Volume of the pyramid = x²(x+2)/3
Volume of the pyramid = (x³+2x²)/3 cm³

3. Problem 2: Suppose a radio manufacturer has the total cost function C (x) = 43x + $ 1850 and the revenue function R (x) = $ 80x. Where "x" is the number of radios manufactured and sold. Find:
plissssssssssssss helpppp
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.
