The area of the semicircle is A = 1187.9 cm².

<h3>What is the area of a circle?</h3>

The area of a circle with a radius of r is A = πr².

Given that, the diameter of the semicircle is 55 cm.

The radius of the semicircle is,

r = 55/2

The area of a semicircle is given by,

A = (1/2)πr²

Substitute the values,

A = (1/2)π(55/2)²

A = 1187.9

Hence, the area of the semicircle is A = 1187.9 cm².

Explain How do you find factors of the polynomial

balandron [24]

Answer:

Step-by-step explanation:

"For a polynomial, no matter how many terms it has, always check for a greatest common factor (GCF) first. Literally, the greatest common factor is the biggest expression that will go into all of the terms. Using the GCF is like doing the distributive property backward.

If the equation is a trinomial — it has three terms — you can use the FOIL method for multiplying binomials backward.

If it’s a binomial, look for difference of squares, difference of cubes, or sum of cubes.

Finally, after the polynomial is fully factored, you can use the zero product property to solve the equation."

Miller Company’s total sales are $123,000. The company’s direct labor cost is $14,760, which represents 30% of its total convers

lana66690 [7]

1.

Direct labor cost = $14760

This is 30% of total conversion cost so, conversion cost = 14760/30%

= $49200

Total conversion cost = Direct labor + Manufacturing overhead

Manufacturing overhead = Total conversion cost - Direct labor

=49200-14760 = $34440

Hence, The total manufacturing overhead cost= $34440

2.

Direct labor = $14760

This is 40% of prime cost. So total prime cost = 14760/40%

= $36900

Total prime cost = Direct material + Direct labor

Direct material = Total prime cost - Direct labor

= 36900 - 14760 = 22140

Hence, the total direct materials cost = $22140

3.

Total manufacturing cost = Direct materials + Direct labor + Manufacturing overhead

= 22140+14760+34440 = $71340

4.

Variable selling and administrative cost = 5% of 123000

=$ 6150

5.

Total variable cost = Direct materials + Direct labor + Sales commission

= 22140 + 14760 + 6150 =$43050

6.

Fixed selling and administrative expense = Total selling and administrative expense - Sales commission = 18450-6150 = $12300

Total fixed cost = Manufacturing overheads + Fixed selling and administrative expense

= 34440+12300 = $46740

7.

Total contribution margin = Sales - Total variable cost

= 123000 - 43050 = $79950

The penny size of a nail indicates the length of the nail. The penny size d is given n 1by the literal equation d=4n−2, where n

Mars2501 [29]

Answer:

a) $n=\frac{d+2}{4}$

b)

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches

Step-by-step explanation:

Complete Question:

The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is the length (in inches) of the nail.

a) Solve equation for n

b) Use part (a) to find length of nails with the following penny sizes: 3, 6, 10.

Solution:

a)

We use algebra and take 2 to the other side and divide to solve for n. Shown below:

$d=4n-2\\d+2=4n\\n=\frac{d+2}{4}$

So,

n = (d+2)/4

b)

Since we have to find length of nails, we plug in 3, 6, and 10 respectively into d of the formula we found in part (a).

When d = 3

n = (3+2)/4 = 5/4 inches

When d= 6

n = (6+2)/4 = 2 inches

When d = 10

n = (10+2)/4 = 3 inches
