Answer 1

Answer:

  k = 110

Step-by-step explanation:

You want the integer multiple of pi that is the area of 300° of a donut with inner radius 8 cm and outer radius of 14 cm.

Area of a circle

The area of a circle is given by the formula ...

  A = πr²

Then the area of the outer circle is ...

  A = π(14 cm)² = 196π cm²

The area of the inner circle is ...

  A = π(8 cm)² = 64π cm²

Donut area

The area of the whole donut is the difference of these areas:

  whole donut area = (196 -64)π cm² = 132π cm²

Shaded area

The shaded area of the figure represents 300° of the 360° full donut. The area is proportional to the central angle, so the shaded area is ...

  shaded area = (300°/360°)×whole donut area

  shaded area = 5/6 × 132π cm² = 110π cm²

Comparing this to the expression kπ cm², we see that ...

  k = 110

Kevin worked his 40 regular hours last week, plus 4 hours at the time-and-a-half rate. His gross pay was $756. What was his hourly rate?

Answers

Kevin put in 40 regular hours last week in addition to 4 hours at the overtime rate. He received $756 in gross pay. The hourly rate of Kevin is $126.

Given that,

Kevin put in 40 regular hours last week in addition to 4 hours at the overtime rate.

He received $756 in gross pay.

We have to find the hourly rate of Kevin.

Let h be the hourly rate.

Then

1.5h be the overtime rate.

Reg pay+ Overtime pay=Total pay

40h+4(1.5h)=756

40h+6h=756

46h=756

h=756/40

h=$126

Therefore, the hourly rate of Kevin is $126.

Find the Total Surface area of the cylinder.

Answers

The total surface area of the cylinder is [tex]477.28cm ^2[/tex]

The surface area of ​​a cylinder can be defined as the amount of space covered by the plane of the base of the cylinder and the curved surface of the cylinder. The total area of ​​a cylinder includes the area of ​​his two bases of a circular cylinder  and the area of ​​the curved surface. Surface area is expressed in square unitsThe total surface area of ​​a cylinder is the sum of the areas of its circular top and bottom and  curved surfaces.  T.S.A = face up + face down + C.S.A  The total  area of ​​a cylinder of radius r and height h is given by [tex]T.S.A = 2 \pi r(r + h)[/tex]     ...(1)  where [tex]\pi = 3.14[/tex]

Answers

The line segment's slope represents the period during which the speed decreases is b. The slope is -10.

What is the line segment's slope?

The slope of a line segment measures the steepness of the line segment.

The slope is the ratio of the rise (the change in vertical height, y, between the endpoints) over the run (the difference in horizontal length, x, between the endpoints.

Data and Calculations:

Elapsed Time (sec)     Speed (mph)

5                                       15

6                                       15

The Slope of the line segment during speed decreases = y₂ - y₁ ÷ x₂ - x₁.

We get that the solution for this inequalities will be x ≤ - 4.5.

We are given the inequalities:

- 2 x - 3 ≥ 6 or 3 ( x - 4 ) < - 6

For - 2 x - 3 ≥ 6:

Add 3 to both sides:

- 2 x - 3 + 3 ≥ 6 + 3

- 2 x ≥ 9

Divide both sides by - 2

- 2 x / - 2 ≤ 9 / - 2

x ≤ - 4.5

For 3 ( x - 4 ) < - 6:

Divide both sides by 3

x - 4 < - 6

Add 4 to both sides:

x - 4 + 4 < - 6 + 4

x < - 2

We get

x ≤ - 4.5 or x < -2

x will then be:

x ≤ - 4.5

Therefore, we get that the solution for this inequalities will be x ≤ - 4.5.

A numerical expression to represent the greatest total number of fish that could be in both aquariums is Number in Tiger barb + number in giant danios.

The Greatest number of fishes that could be in both aquariums is 14.

We are given that;

Tiger barbs = 30 gallon aquarium

Giant danios = 20 gallon aquarium

Tiger barb = volume / length

Tiger barb = 30 / 3

Tiger barb = 10 fishes

Giant danios = volume / length

Giant danios = 20 /5

Giant danios = 4 fishes

Numerical expression is:

Number in Tiger barb + number in giant danios

= 10 + 4 = 14

Therefore, the correct numerical expression that represents the greatest total number of fish that could be in both aquariums is Number in Tiger barb + number in giant danios.

3. When you buy indirectly produced material: Debit the inventory of raw supplies.

4. Using indirect materials results in: Credit the inventory of raw commodities.

5. Direct labor used: Debit Work in Process Inventory.

Explanation:

1. When you divide up overhead expenses among jobs: Give factory overhead credit. Factory overhead is a cost that cannot be directly attributed to the goods but is incurred throughout the manufacturing process of completed goods.

2. When paying production overhead: debit the factory utilities. Factory overhead is defined as a cost incurred during the production of completed goods that is not directly related to the products.

3. When you buy indirectly produced material: Debit the inventory of raw supplies. The cost of all resources, such as component components, that a company has on hand but have not been used in the manufacture of finished items or work in progress is included in the raw materials inventory.

4. Using indirect materials results in: Credit the inventory of raw commodities. The total cost of all resources, like as component components, that a company has on hand but haven't been used to produce finished goods or work in progress is known as raw materials inventory.

she bake in the afternoon?

Answers

When the Saffron bales 324 pastries in the morning and some in the afternoon, if she sells 584 pastries and at the end of the day she has 52 pastries left, the total number of pastries in the afternoon is 312

The  total number of pastries she sells=584 pastries

The number of pastries left at the end of the day=52 pastries

The total number of pastries she bakes=584+52

=636 pastries

Number of pastries she bakes in the morning=324 pastries

Subtract the number of pastries bakes in the morning from the total number of pastries she bakes

Number of pastries she bakes in the morning=636-324

=312 pastries

Hence, when the Saffron bales 324 pastries in the morning and some in the afternoon, if she sells 584 pastries and at the end of the day she has 52 pastries left, the total number of pastries in the afternoon is 312
