The Six members of the homecoming decorating committee want to make 525 people flowers for the homecoming dance each flower takes 4 1/2 minutes to make about how long will each member of the committee have to spend making flowers

Answers

the answer is 2362 1/2 minutes

Final answer:

To find out how long each member of the committee will have to spend making flowers, we need to divide the total time needed to make the flowers by the number of committee members.

Explanation:

To find out how long each member of the committee will have to spend making flowers, we need to divide the total time needed to make the flowers by the number of committee members.

Each flower takes 4 1/2 minutes to make, so the total time needed is 525 * 4 1/2 minutes. We can convert 4 1/2 minutes to 4.5 minutes, and then multiply it by 525 to get the total time needed.

Finally, we can divide the total time by the number of committee members (6) to find out how long each member will have to spend making flowers.

In August Emily’s clothing store sold 460 shirts with the ration of short sleeve to long sleeve being 3:7. How many short sleeve shirts where sold?

Answers

Emily's clothing store sold 138 short sleeve shirts, calculated by dividing the total shirts by the sum of the ratio parts (10) and multiplying the result by the short sleeve part of the ratio (3).

The question asks how many short sleeve shirts were sold if the ratio of short sleeve to long sleeve shirts is 3:7 and a total of 460 shirts were sold. To find the answer, first calculate the total parts of the ratio by adding both parts of the ratio together, which is 3+7=10.

Then, divide the total number of shirts by the total parts of the ratio to find out how many shirts each part of the ratio represents: 460/10=46. Since the ratio of short sleeve shirts is 3 parts, multiply the number each part represents by 3 to get the number of short sleeve shirts: 46*3=138. Therefore, Emily's clothing store sold 138 short sleeve shirts.

An apparel company uses a trucking service to deliver products from its warehouse to its retail outlets. For a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven. The apparel company has a budget of less than $950 per trip. The apparel company’s owner wants to find out which retail outlets can be serviced with the given requirements.
Represent this situation in an inequality.

Answers

Answer:

The inequality will be:  [tex]x<560[/tex] , where [tex]x[/tex] is the distance of the retail outlets from the warehouse.

Step-by-step explanation:

For a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven.

Suppose, the number of miles driven is  [tex]x[/tex]

So, the charge for  [tex]x[/tex] miles will be:  [tex]\$1.25x[/tex]

and the total charge for a one-way trip will be:  [tex]\$250+\$1.25x[/tex]

Given that, the apparel company has a budget of less than $950 per trip.

So, the inequality will be.........

[tex]250+1.25x<950\\ \\ 1.25x<950-250\\ \\ 1.25x<700\\ \\ x<\frac{700}{1.25}\\ \\ x< 560[/tex]

Thus, the retail outlets which are less than 560 miles away from warehouse can be serviced with the given requirements.

The volume of a cylindrical soap dispenser is modeled by the expression below.select the true statement.a. the expression (x + 1)2 represents the height of the soap dispenser.b. the expression (x + 1)2 represents the radius of the soap dispenser.c. the factor 4x + 1 represents the height of the soap dispenser.d. the factor 4x + 1 represents the area of the base of the soap dispenser.

Answers

Answer:

The expression [tex](x+1)^2[/tex] represents the radius of the soap dispenser.

The expression [tex]4x+1[/tex] represents the height of the soap dispenser.

Step-by-step explanation:

The question says that the soap dispenser is in the form of a cylinder.

Now, we find the volume of the cylinder by using the given formula:

[tex]V= \pi r^2 h[/tex], where V represents the volume, 'r' represents the radius, and 'h' represents the height of the cylinder.

Now, the volume is the product of radius squared and the height, if they both are functions of [tex]x[/tex], then the function to represent the volume must have cubic exponents.

Since, the radius is squared in the formula and it is a function of [tex]x[/tex] that implies that the function of radius must have square as the exponent of [tex]x[/tex], therefore, the expression [tex](x+1)^2[/tex] will represent the radius of the soap dispenser and the expression [tex](4x+1)[/tex] represents the height of the soap dispenser.

You multiply by 1.12 to find your answer

Answer: 1.12

To get this answer, you would represent 12% as 0.12 (move the decimal point 2 spots to the left to go from 12.0% to 0.12) then you add on 1 to get 1+0.12 = 1.12

Another way to think about it is to have 100% + 12% = 112%, so the new price is 112% of the old price. For example, if the car was $100 and you increase the price by 12%, then it jumps to $112. Notice how 1.12*(old price) = 1.12*100 = 112 = new price

George had $235 in his checking account he withdrew $20 each day on Monday Tuesday and Wednesday George got paid on Friday and deposited $130 into his checking account then on Saturday he wrote two checks one for a $167 and one for $212 what was the checking balance after writing the checks

Answers

235$ and if you withdraw 20$ on three days thats 60$ so if we remove that from the account we have 175$ left.

Then on Friday when he got paid he put 130$ into the bank he has 175+130=305$

If he wrote a check 1 for 167$ and 1 for 212$ thats his account balance - 212 then -167 = 305 -378 so he has a balance of -73

Final answer:

The checking balance after writing the checks is -$74.

Explanation:

To calculate the checking balance after writing the checks, we need to keep track of George's transactions:

Starting balance: $235Monday: Withdraw $20 (-$20)Tuesday: Withdraw $20 (-$40)Wednesday: Withdraw $20 (-$60)Friday: Deposit $130 (+$70)Saturday: Write a check for $167 (-$97)Saturday: Write a check for $212 (-$309)

To find the final balance, we add the positive values (deposits) and subtract the negative values (withdrawals and checks):

Starting balance ($235) + Deposits ($130) - Withdrawals ($60) - Checks ($167 + $212) = $235 + $130 - $60 - $167 - $212 = -$74

Therefore, the checking balance after writing the checks is -$74.

Tony wants to buy a new collar for each of his 4 dogs. The collars come in a choice of 9 different colors.

Step 2 of 2 : How many selections of collars are possible if repetitions of colors are not allowed?

Answers

There are 9 ways to choose the collar color of the first dog, 8 ways to choose the collar color of the second dog (9 choices - the color for the first dog), 7 ways to choose the collar color of the third dog (9 choices - the colors for the first 2), and 6 ways to choose the collar color of the fourth dog (9 choices - the colors of the first three). Total is 9 * 8 * 7 * 6 = 3024 ways.

There are 126 possible selections of collars for Tony's 4 dogs if repetitions of colors are not allowed.

What is permutation?

The number of selections of collars possible if repetitions of colors are not allowed, we can use the concept of permutations.

Using the formula for permutations without repetition, we can calculate this as:

9P4 = 9! / (9 - 4)!

= 9! / 5!

= (9 * 8 * 7 * 6) / (4 * 3 * 2 * 1)

= 3024 / 24

= 126

This shows that  126 possible selections of collars for Tony's 4 dogs if repetitions of colors are not allowed.

So his cost, y, for x items is represented by y=1,800 + 400x. He can sell the cabinets for $600. So his revenue, y, is represented by y=600x. The solution to this system of equations is his break-even point, the point beyond which he starts making a profit. How many cabinets must he sell to break-even?

Answers

The number of cabinets he must sell to breakeven is 9.

How many cabinets must he sell?

Breakeven is when the total cost and the revenue is zero. At the breakeven point, profit is zero.

Breakeven : total cost = revenue

1800 + 400x = 600x

In order to determine the value of x, take the following steps:

Combine similar terms:

1800 = 600x - 400x

Add similar terms together

1800 = 200x

Divide both sides of the equation by 200

x = 1800 / 200

x = 9

To break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.

The break-even point occurs when the total cost is equal to the total revenue.

We can find this point by setting the cost equation and the revenue equation equal to each other and solving for x :

Set the cost and revenue equations equal :

  Given that the cost equation is y = 1,800 + 400x, and the revenue equation is y = 600x , set these two equations equal to find the break-even point:

[tex]\[ 1,800 + 400x = 600x. \][/tex]

Rearrange the equation :

  Subtract 400x from each side:

 [tex]\[ 1,800 = 200x. \][/tex]

Solve for x :

  Divide by 200 to isolate x :

 [tex]\[ x = \frac{1,800}{200} = 9. \][/tex]

Therefore, to break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.

What is the prime factorization of 135?

Answers

135 is a composite number.

135 = 1 x 135, 3 x 45, 5 x 27, or 9 x 15.

Factors of 135: 1, 3, 5, 9, 15, 27, 45, 135.

Prime factorization: 135 = 3 x 3 x 3 x 5, which can also be written 135 = 3³ x 5

The prime factorization of 135 is 3^3 × 5.

How did we get the value?

The prime factorization of 135 is obtained by finding the prime numbers that divide 135 evenly, repeatedly dividing until the quotient is no longer divisible by any prime numbers.

Starting with the number 135, we can see that it is divisible by 3, so we divide 135 by 3:

135 ÷ 3 = 45

Now, we repeat the process with 45. It is also divisible by 3:

45 ÷ 3 = 15

Continuing, we divide 15 by 3:

15 ÷ 3 = 5

Now we have reached a quotient of 5, which is a prime number. We cannot divide it any further, so we have obtained the prime factorization of 135 as follows:

135 = 3 × 3 × 3 × 5

Therefore, the prime factorization of 135 is 3³ × 5.

At midnight, the temperature was 30 degrees F. By 6:00 a.m., it had dropped 5 degrees and by noon, it had increased by 11 degrees. What was the temperature at noon?

Answers

Answer: 36 degrees


Step-by-step explanation:

subtract 5 from 30=25

add 11 to 25

25+11=36



Final answer:

Considering the temperature changes throughout the day, the temperature at noon was 36 degrees F.

Explanation:

If the temperature started at 30 degrees F at midnight, and it dropped 5 degrees by 6:00 a.m, the temperature at 6:00 a.m. was 30 - 5 = 25 degrees F. Then, if the temperature increased by 11 degrees F by noon, we just add this increase to the temperature at 6:00 a.m. This results in 25 + 11 = 36 degrees F. So, the temperature at noon was 36 degrees F.
