Philip wants to give $156 to United Way, but he wants to give it over the coming year. If he signs up to have a regular amount withheld from his savings each week and given to United Way, how much will be taken from his pay for that purpose every week?
Answer:
Hence in 52 weeks he will distribute 156 $ with 3 $ per week from his pay
Step-by-step explanation:
Given:
156 $ to United way for a year.
With each weeks.
To Find:
How much amount he will take for pay for giving to United way.
Solution:
He wants to give money to united way in a year
So there are 365 days per year
And he held money from is his pay every week
So there 7 days per weeks.
Hence Total number of weeks in a year will given by,
=365/7
=52 weeks per year
Now he held every week from his pay to United way
And Total amount to distribute is about 156 $ in 52 weeks.
So Every week amount will be
=156$/52
=3 $ /week
Final answer:
To donate $156 to United Way over a year, Philip needs to have $3 withheld from his savings each week.
Explanation:
To calculate the amount Philip will need to have withheld every week to give $156 to United Way over a year:
First, find the number of weeks in a year (52 weeks).
Divide the total amount to be donated ($156) by the number of weeks in a year to find the weekly amount: $156 ÷ 52 = $3.
Therefore, Philip will need to have $3 withheld from his savings each week to donate $156 to United Way over a year.
A planet's radius is approximately 1,534 mi. About two-thirds of the planet's surface is covered by water.
Enter an estimate for the land area on the planet. Round the answer to the nearest million.
Answer:
ok so the earth radius is 1534mi so if that is the radius than the area is 7.39×10^6so then you divide that into 3 pieces so each piece would be 2,463,333.3333 the nearest million would be 2,000,000
Step-by-step explanation:
To find the land area of a planet with a radius of approximately 1,534 miles and two-thirds water coverage, we calculate the total surface area and take one-third of that as the land area. The land area is approximately 9,867,658 square miles, which rounds to 10 million square miles.
To estimate the land area on the planet with a radius of 1,534 miles that is two-thirds covered by water, we first calculate the planet's total surface area using the formula for the surface area of a sphere, which is 4πr². Plugging in the radius:
Total surface area = 4π(1,534)² ≈ 29,602,975 square miles.
Since two-thirds of the planet's surface is covered by water, one-third is land. Therefore, the land area is approximately:
Land area = ([tex]\frac{1}{3}[/tex]) × Total surface area ≈ ([tex]\frac{1}{3}[/tex]) × 29,602,975 ≈ 9,867,658 square miles.
When rounded to the nearest million, the estimate for the land area is 10 million square miles.

what power of 7 is 2041? 2041=7^6-2x
Answer:
x = 1
Step-by-step explanation:
2401 = 7⁶⁻²ˣ
7⁴ = 7⁶⁻²ˣ
4 = 6 - 2x
2x = 6 - 4
2x = 2
x = 1
Final answer:
There is no integer power of 7 that exactly equals 2041, as 7 to the power of 4 is 2401, which is the closest integer power of 7 that is higher than 2041.
Explanation:
The question asks to determine the power of 7 that equals 2041, which is written mathematically as 2041 = 7x. To solve this, one approach is to estimate and refine by trying different powers of 7 until we get close to 2041. Here's how the estimation process could work:
Start with lower powers of 7 like 72 = 49, and increase the exponent.
Notice that 73 = 343 and 74 = 2401.
Since 2401 is just above 2041, we suspect our answer will be close to 4 but slightly less.
Checking with a calculator or using a division strategy, we can confirm that 2041 is slightly below 74, making it clear there's no integer power of 7 that equals 2041.
Therefore, there isn't an integer power of 7 that precisely equals 2041.

A 3-column table with 4 rows. Column 1 has entries Computer repair, sales tax, gratuity, shipping. Column 2 is labeled Store A with entries 1,200 dollars, 6 percent, 15 percent, Free. Column 3 is labeled Store B with entries 1,350 dollars, 7 percent, 15 percent, 2 percent of total price. What is the cost of the repair and sales tax combined at Store B?
Answer:
$1,444.50.
Step-by-step explanation:
To calculate the combined cost of the repair and sales tax at Store B:
Cost of repair at Store B: $1,350
Sales tax rate at Store B: 7%
Now, let's calculate the sales tax:
Sales tax = 1,350 × 7/100 = 1,350 × 0.07 = 94.50
Next, add the sales tax to the repair cost:
Total cost = 1,350 + 94.50 = 1,444.50
Thus, the combined cost of the repair and sales tax at Store B is $1,444.50.

A punch bowl is in the shape of a cylinder. the height of the punch bowel is 10inches and the diameter of the punch bowl is 14inches what is the volume of the punch you need to fill your punch bowl 1 inch from the top. use 3.14 and round to the nearest whole number
Answer:
The volume of the punch bowl is 1385 cubic inches.
Step-by-step explanation:
Cylinder:
The volume of the cylinder is [tex]\pi r^2 h[/tex], where r is radius of the cylinder and h is height of the cylinder.The lateral surface area is [tex]2\pi rh[/tex].Total surface area is [tex]2\pi r(r+h)[/tex].Given that,
A punch bowl is in the shape of a cylinder.
The diameter of the punch bowl is 14 inches.
Then the radius of the punch bowl is [tex]=\frac{14}{2}[/tex] = 7 inches.
The height of the punch bowl is = 10 inches.
The punch bowl is need to fill 1 inch from the top.
So, we need to fill the punch bowl = (10-1) =9 inches.
The volume of the punch bowl is = [tex]\pi r^2 h[/tex]
[tex]=(3.14 \times 7^2\times 9)[/tex] cubic inches
≈1385 cubic inches.
Final answer:
To fill a cylindrical punch bowl to 1 inch below the top, you would need to calculate the volume using the formula V = πr²h with the radius being half the diameter, and the height being the bowl's height minus 1 inch. Using the given dimensions, the volume needed is 1383 cubic inches of punch.
Explanation:
Calculating the Volume of a Cylinder Punch Bowl
To calculate the volume of the punch needed to fill a cylindrical punch bowl, we need to use the volume formula for a cylinder, which is V = πr²h. The diameter of the punch bowl is given as 14 inches, so the radius (r) is half of that, which is 7 inches. The height (h) of the punch needed is the height of the bowl minus 1 inch, which is 10 inches - 1 inch = 9 inches. Now, we can plug these values into the formula and use 3.14 for π:
V = π × r² × h = 3.14 × (7 inches)² × 9 inches
Doing the calculation:
V = 3.14 × 49 sq inches × 9 inches = 3.14 × 441 cubic inches = 1383.14 cubic inches. When we round this to the nearest whole number, we get a volume of 1383 cubic inches of punch needed to fill the bowl to the desired level.
you find a mutual fund that offers approximately 4 % APR compounded monthly. How much will you need to invest each month for the next 6 months in order to have $500?
Final answer:
To reach $500 with a 4% APR compounded monthly, you would need to invest $1.67 each month for the next 6 months.
Explanation:
To calculate how much needs to be invested each month for the next 6 months to have $500 with a 4% APR compounded monthly:
Calculate the monthly interest rate using APR: 4% APR = 4%/12 = 0.3333% monthly rate.Use the present value formula: $500/(1 + 0.3333%) = $500/1.0033333 = $498.33.Subtract the present value from the future value to find the monthly investment required: $500 - $498.33 = $1.67.This calculation ensures the necessary monthly investment to reach the desired future value, facilitating financial planning and goal setting.

You design a frame to surround a rectangular photo. The width of the frame is the same on every side as shown. write a polynomial in standard form that represents the combined area of the photo in the frame. find the combined area of the photo in the frame when the width of the frame is 4 inches.
Answer:
A is 4x^2+84x+440 and B=840 square inches
Step-by-step explanation:
A is 4x^2+84x+440 and B=840 square inches
The task for a is to write a polynomial in standard form that represents the combined area of the photo and the frame. First, lets start with the bottom of the picture and frame. On the bottom, you have 2x+ 22 inches. Then the side of the picture and frame is 2x+20 inches. Writing in polynomial form, it would be (2x+22)(2x+20). You would get 4x^2+84x+440 since you are using the FOIL method. Now for part b, we know that the width of the frame(or x) is 4 inches. Now we plug that into the equation. 84x is 84x4. 84x4=336 x^2 is 16. There are four of those as you can see in the equation so 16x4=64
336+64=400 inches Frame= 400 inches
400 inches plus the picture(440 inches) = 840 square inches.
Length of the rectangular photo = 22 inches
Width of the rectangular photo = 20 inches
Since, width of the frame outside the photo = x inches
Therefore, increase in length and width of the photo with frame = (x + x)
= 2x inches
Length of the photo with frame = (22 + 2x) inches
Width of the photo with frame = (20 + 2x) inches
Combined Area of the photo in the frame = Length × Width
= (22 + 2x)(20 + 2x)
= 22(20 + 2x) + 2x(20 + 2x)
= 440 + 44x + 40x + 4x²
= 4x² + 84x + 440
Therefore, polynomial representing the combined area of the photo in the frame will be (4x² + 84x + 440) square inches.
If width of the frame = 4 inches
Combined area of the photo = 4(4)² + 84(4) + 440
= 840 square inches

The number of students in the classroom is 24, as it is the smallest multiple of 2, 3, 4, 6, and 8 that is between more than 20 and fewer than 30.
The student is given a number puzzle in a mathematics classroom setting. Based on the teacher's hints, the number of students in the classroom should be a common multiple of 2, 3, 4, 6, and 8 that also fits within the given range of between more than 20 and fewer than 30. We need to find the least common multiple (LCM) of these numbers that fits the criteria.
First, realize that since the number must be divisible by 8, it must be at least 24 since 16 is too low.
Next, confirm if 24 is also divisible by 2, 3, 4, and 6. It is indeed, as 24=2x12, 24=3x8, 24=4x6, and 24=6x4.
Because 24 is the only number between 20 and 30 that is divisible by all the given numbers, it is the answer.
Thus, the number of students in the classroom is 24.
A company made a storage container with sheet steel walls. The container was in the shape of a rectangular prism, as shown below. Suppose the total cost of the sheet steel was $8384. How much did the sheet steel cost per square meter?
Answer:
$ 42.78
Step-by-step explanation:
See attachment for the figure
The formula of the lateral area of the rectangular prism is:
LA = perimeter of base × height
Given:
The length of the base 'l' = 9 m
The width of the base 'w'= 5 m
The height of the prism 'h'= 7 m
perimeter of the base can be determined by
Perimeter of base = 2(l + w ) =>2(9 + 5)
Perimeter of base = 28 m
By using the formula of the lateral area
LA = 28 × 7
LA = 196 m²
Required:
sheet steel cost per square meter=?
Given: The total cost of the sheet steel was $8384
LA = 196 m²
By Dividing the cost by the lateral area, we'll know our unit cost
therefore, The unit cost = 8384 ÷ 196
The unit cost =$ 42.78
The sheet steel costed $42.78 per square meter

If the median of five consecutive even integers is 20, what is the value of the smallest integer?
Answer:
16
Step-by-step explanation:
Median means the middle number. So you can look at it like this:
a,b, 20, c,d
Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.
This should be your answer:
16, 18, 20, 22, 24
Consecutive, and even.
Final answer:
The smallest integer in the set of five consecutive even integers with a median of 20 is 16. This is calculated by recognizing the median as the middle value, and subtracting 4 (for two even steps) from the median.
Explanation:
If the median of five consecutive even integers is 20, we can determine the value of the smallest integer by understanding the property of consecutive even numbers and the nature of the median in a symmetrically distributed set. Since the median of this set is the middle value, the five consecutive even numbers can be represented as:
x
x + 2
20 (the median)
x + 4
x + 6
The median, 20, is the third value in this ordered set. To find the smallest value, x, we look two even numbers behind 20. Since consecutive even numbers increase by 2 with each step, we subtract 4 from 20 to find the smallest value.
20 - 4 = 16
Therefore, the smallest integer in this set of five consecutive even numbers is 16.
