Len is baking a square cake for his friend wedding. When served to the guests, the cake will be cut into square pieces 1 inch on the side. The cake should be large enough so that 121 guests get one piece. How long should each side of the cake be?

Answers

You would just need to take the square root of 121 since it is square. So:

√121= 11 inches per side

Final answer:

Len must bake a square cake that's 11 inches on each side to satisfy 121 guests with square pieces of cake.

Explanation:

To calculate the length of each side of the cake, we will use the concept of square root. The square root of a number gives the length of the side of a square whose area is that number. The number of guests, who will each receive one square piece of cake, is the area of the cake in square inches. So, we need to calculate the square root of 121, which is the number of guests.

Step 1: Write down the number of guests, 121.

Step 2: Calculate the square root of the number from step 1. The square root of 121 is 11.

Therefore, the length of each side of the cake should be 11 inches.

Which expression has a value of 15 when n = 7?1: 43 minus 5 n
2: 3 n minus 5
3: 6 n minus 28
4: 19 minus StartFraction 28 Over n EndFraction

Answers

Answer:

19-(28)/(n) is the expression with the value of 15 when n = 7

Step-by-step explanation:

To find the expression whose value is 15, substitute the value of n = 7 in each given expression.

Expression 1:

43-5n

Substitute the value of n & simplify,

43-5(7)

43-35=8

Since the value of the expression is 8 which is not equal 15.

Hence expression 43-5n does not have value of 15 when n = 7.

Expression 2:

3n-5

Substituting the value of n & simplify,

3(7)-5

21-5=16

Since the value of the expression is 16 which is not equal 15.

Hence expression 3n-5 does not have value of 15 when n = 7.

Expression 3:

6n-28

Substituting the value of n & simplify,

6(7)-28

42-28=14

Since the value of the expression is 14 which is not equal 15.

Hence expression 6n-28 does not have value of 15 when n = 7.

Expression 4:

19-(28)/(n)

Substituting the value of n & simplify,

19-(28)/(7)

19-4=15

Since the value of the expression is 15 which is equal 15.

Hence expression 19-(28)/(n)has the value of 15 when n = 7.

Which of the following expressions shows the expression 1/2x+3−2/5x+1 in simplest form?

Hey there!

1/2x + 3 - 2/5x + 1

COMBINE the LIKE TERMS

= (1/2x - 2/5x) + (3 + 1)

1/2x - 2/5x = 1/10x

3 + 1 = 4

= 1/10x + 4

Therefore, your answer is: 1/10x + 4

The cost of $500,000 worth of 20-year term life insurance for Derek is $96.21 per month. If Derek's employer covers 85% of this cost, how much is deducted from Derek's gross income per year for life insurance?

Answers

Alright, the first thing we should have to do is find the total cost per year of his insurance. To do that, we multiply $96.21 by the 12 months in a year to get $1154.52. This is the cost of his insurance per year.

Next, we need to find out how much his boss covers, which we know is 85% of the total cost. SO what we can do is multiply the yearly cost ($1154.52) by the percent his boss covers (.85) to get $981.342. This is how much his boss covers per year.

Lastly, to find out how much Derek pays for insurance yearly, we just need to subtract how much his boss pays ($981.342) from the total yearly cost  ($1154.52), which leaves us with $173.178, which is how much Derek pays yearly for his insurance, which should be your answer.

Final answer:

Derek pays 15% of the yearly cost of his life insurance, which amounts to $173.18 per year.

Explanation:

The total cost of Derek's life insurance for a year is calculated by multiplying the monthly fee by the number of months in a year (i.e. $96.21 x 12 = $1154.52). As Derek's employer is covering 85% of the cost, Derek is responsible for the remaining 15%. Therefore, the yearly cost deducted from Derek's gross income would be $1154.52 x 15% = $173.18. It's crucial to understand that these costs can vary depending on the insurance coverage, the employee benefits provided by the employer, and the individual's income.
