What value of X and Y will make all 3 lines parallel?
Answer:
x = 19
y = 14
so c is the correct answer
Step-by-step explanation:
for them to be parallel, 5x + 15 has to equal 110 because of the 70 on the opp side making the two supplementary, and 5y has to equal 70
so 5y = 70, making y = 14
then 5x + 15 = 110
to 5x = 95
so x = 19

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.

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.

What number goes in the cell in row y, below 4?
Answer:
10.
Step-by-step explanation:
The formula for this table is y=x+6. plug in 4 and you get 10
Answer:
10
Step-by-step explanation:
Don't just think: 6,7,8,9, oh it must be 10.
When x is 0, y is 6. That means no matter what 6 is added to x. So if we look at when x is 2, y = 8. Lets subtract the 6 from the 8 and we get 2. So the x is not multiplied by anything.
The equation is y = x+6.

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.
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.
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 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
How do you find the area of this shape?
Answer:
the area is 20
Step-by-step explanation:
If you put the triangles together, it makes a perfect square of 4, 16+4 = 20
A student solved this problem by working backward.
Jared has some flowers. He has 6 more red flowers than yellow flowers. He has twice as many orange flowers as red flowers. He has 4 yellow flowers. How many flowers does Jared have altogether?
Student's solution:
Jared has 4 yellow flowers.
He has 6 more red than yellow flowers (4 + 6 = 10).
He has twice as many orange flowers as red flowers (10 × 2 = 20).
So Jared has 4 + 10 + 20 = 34 flowers.
Use a similar strategy to solve this problem.
Kathleen has some balloons. She has 7 more silver balloons than gold balloons. She has 3 times as many bronze balloons as silver balloons. She has 5 gold balloons.
How many balloons does Kathleen have altogether
Kathleen has 5 gold balloons, 12 silver balloons, and 36 bronze balloons. By adding the number of each type, she has a total of 53 balloons.
To determine how many balloons Kathleen has altogether, we can work backward just like the student did in the original problem. Here are the steps:
Kathleen has 5 gold balloons.She has 7 more silver balloons than gold balloons, so she has 5 + 7 = 12 silver balloons.She has 3 times as many bronze balloons as silver balloons, so she has 12 × 3 = 36 bronze balloons.Adding them all together: 5 gold + 12 silver + 36 bronze = 53 balloons.Hence, Kathleen has a total of 53 balloons.

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.

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.
