kira earned $25,000 last year. the earnings needed for one social security credit last year was $1,200. How many social security credits did kira earn?​

Answers

Answer: 20

Explanation: You can multiply 1,200 by 20 to get 24,000 which is the highest you can go until you go over 25,000

Answer:

He would get an adding amount to 20

Its simple, just divide 25,000 (his total amount) bc your trying to find how much cards he can buy with his total amount. This would mean 25,000 divided by 1,200 meaning 20. He would have a few more dollars but it would be enough to get a 21'th card. This mean he is stuck with 20 as his amount of cards.

Answers

Answer:

4 toppings

Step-by-step explanation:

13.99-8.99=5

5÷1.25= 4

Laura put 4 toppings on her pizza.

The answer would be 4 toppings.

First you must subtract $13.99 by $8.99 which gives you $5. Then you divide that by the price of a topping which is $1.25. When you divide you get 4.

well, without a calculator, what you can do is

round each choice to a "metric" value, namely 312.5 use 310, and then you can simply multiply it manually 310*310, which is 96100, well, that's too large, so nope.

don't bother with 323.4 because that's even larger.

what is the area of the shaded portion of the circle

Answers

The area of the shaded portion of the circle is option G. 28.5cm²

How did we get the value?

To find the shaded area of a circle, you need to know the radius of the circle and the central angle of the sector that forms the shaded region. The formula for the area of a sector (a portion of a circle) is given by:

[tex]\[ \text{Area of Sector} = \left( \frac{\text{Central Angle}}{360^\circ} \right) \times \pi r^2 \][/tex]

where:

- [tex]\( \text{Central Angle} \)[/tex] is the measure of the angle at the center of the circle (in degrees),

- [tex]\( \pi \)[/tex] is a mathematical constant approximately equal to 3.14159, and

- [tex]\( r \)[/tex] is the radius of the circle.

If the shaded region is not a complete sector but a segment (a portion of the circle bounded by a chord and an arc), you may need to subtract the area of the triangle formed by the radius and the two radii extending to the endpoints of the chord. The formula for the area of the segment is then:

[tex]\[ \text{Area of Segment} = \text{Area of Sector} - \text{Area of Triangle} \][/tex]

One can find the shaded area by:

1. Determine the radius [tex](\( r \))[/tex] of the circle.

2. Find the measure of the central angle [tex](\( \text{Central Angle} \))[/tex] of the sector or segment.

3. Apply the formula to calculate the area of the sector [tex](\( \text{Area of Sector} \))[/tex].

4. If it's a segment, find the area of the triangle formed by the radii and the chord and subtract it from the area of the sector.

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi r^2 \][/tex]

Given that the radius [tex](\( r \))[/tex] is 10, you can substitute this value into the formula:

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi \times (10)^2 \][/tex]

Let's calculate this:

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times \pi \times 100 \][/tex]

[tex]\[ \text{Area of Quarter Circle} = \frac{1}{4} \times 100 \pi \][/tex]

the sides of 2 similar hexagons are in a ratio of 1:3. The area of the smaller hexagon is 12in². Find the area of the larger hexagon

Answers

Answer:

374.12

Step-by-step explanation:

A=33

2a2=3·3

2·122≈374.12297

To solve this problem, we will use the fact that if two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
Let's start by identifying the given information:
1. The ratio of the sides of the two similar hexagons is 1:3.
2. The area of the smaller hexagon is 12 square inches.
We are asked to find the area of the larger hexagon.
Now, since the ratio of the sides of the two hexagons is 1:3, the square of this ratio will tell us the ratio of the areas of the two hexagons. So we must square the side ratio to get the area ratio:
Ratio of sides of hexagons = 1 : 3
Ratio of areas of hexagons = (1^2) : (3^2) = 1 : 9
This means that the area of the larger hexagon is 9 times larger than the area of the smaller hexagon. Now we can find the area of the larger hexagon by multiplying the area of the smaller hexagon by 9:
Area of larger hexagon = Area of smaller hexagon * 9
                       = 12 in² * 9
                       = 108 in²
Therefore, the area of the larger hexagon is 108 square inches.

Which linear inequality is represented by the graph

Answers

Answer:

[tex]y\leq \frac{1}{2} x+2[/tex]

Step-by-step explanation:

Firstly, as seen in the graph, the shaded area is below the graph. This means that [tex]y \leq[/tex]

Next we can look at the slope. It is seen that m=[tex]\frac{1}{2}[/tex]

From these two observations, the only inequality that fits the critera is

[tex]y\leq \frac{1}{2} x+2[/tex]

Answer:

Option A

Step-by-step explanation:

(1) In the given graph a solid line has been given which represent the sign of inequality between two variables.

(2) Moreover this, a should area has been given below the solid line. which represents the sign of "less than" between the variables.

In total between y and x there should be a sign of (≤)

(3) Now this line passes through two points (0,2) and (-4,0) so slope of the line will be = [tex]\frac{y-y'}{x-x'}[/tex]

Therefore, slope =[tex]\frac{2-0}{0+4}=\frac{1}{2}[/tex]

y-intercept of the line has been given as 2

So inequality for this graph will be

y ≤ [tex]\frac{1}{2}[/tex]x + 2

Option A is the answer.

Donald has xxx twenty-dollar bills and 111 ten-dollar bill.
How much money does Donald have?

Answers

The expression representing the total amount of money Donald has is:

[tex]\[ \text{Total money} = 20x + 1110 \][/tex]

To find the total amount of money Donald has, we need to calculate the sum of the value of all the bills.

The value of each twenty-dollar bill is $20, and the value of each ten-dollar bill is $10.

Let's represent the number of twenty-dollar bills as x and the number of ten-dollar bills as 111.

So, the total amount of money Donald has can be expressed as:

[tex]\[ \text{Total money} = \text{Value of twenty-dollar bills} + \text{Value of ten-dollar bills} \]\[ \text{Total money} = 20x + 10(111) \][/tex]

A rectagular, above ground pool is 18 feet long, 9 feet wide, and 54 inches deep. One cubic foot of water weighs about 62.4 pounds. What is the total weight of the water in the pool when it is completely full?

Answers

Answer:

45,489.6 pounds!

Step-by-step explanation:

To solve this problem, first we need to find the volume of the pool.

We know that the dimensions of the pool are:

Width = 9ft

Length = 18ft

Height = 54in = 4.5 ft

So the volume of the pool is:

Volume = Width x Length x Height = 9ftx18ftx4.5ft = 729ft^3

We know that one cubic foot of water weights about 62.4 pounds. To fill the  pool, we will need 729ft^3 of water.

So the weight of the water is:

Weight = 729ft^3 x 62.4 pounds/ft = 45,489.6 pounds!

Text is 3. illustrations is 2. based on the ratio what is the number of pages of text when there are 22 pages

Answers

Answer:

Step-by-step explanation:

The ratio of the number of pages of text to illustration is given 3:2. This implies that for every 2 pages of illustrations, there are 3 pages of text. Therefore, for 22 pages of illustration we shall have;

(22*3)/2 = 33 pages of text .

Using ratio and proportions this is solved as follows;

[tex]\frac{2}{3}=\frac{22}{x}[/tex]

where x is the corresponding number of pages of text. The next step is to cross multiply and solve for x;

x = (22*3)/2 = 33 as shown above.

6) 3.14•3
Pleaseeeeeeeseeeeee

Answers

Answer:

Step-by-step explanation:

If you are given  3.14 · 1.5 · 1.5, you actually have 3.14 · 1.5²

If you match this up to the area-of-a-circle formula A = πr²

you can see right away that r = 1.5.  If r = 1.5, d = 2(1.5) = 3.0

I do not quite understand what you were trying to present in your

"And the other is the area 3.14•3

2) 3.14•1.25" so am unable to help you with it.

Final answer:

To find the diameter and radius of a circle, divide the given circumference by 3.14 to find the diameter, and then divide the diameter by 2 to find the radius. To calculate the area, use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle.

Explanation:

To find the diameter and radius of a circle, we need to understand the formulas and calculations involved. The diameter is the distance across the circle passing through the center, and it is twice the length of the radius. The radius is the distance from the center of the circle to any point on its edge.

Finding the Diameter and Radius:

To find the diameter, you need to divide the given circumference by 3.14. For example, to find the diameter of 3.14 • 1.5 • 1.5, you would divide this value by 3.14. To find the radius, you divide the diameter by 2. For example, if the diameter is 6, then the radius is half of that, which is 3.

So, depending on the given values, you can use the formulas mentioned above to solve for the diameter and radius of a circle.

Calculating the Area:

To calculate the area of a circle, you need to use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle. Substitute the given value of the radius into the formula and solve for the area. For example, if the radius is 3, then the area would be 3.14 • 3².

Using the formulas and steps above, you can find the diameter, radius, and area of a circle based on the given values.

A. 142,410
B. 170,892
C.83,345

Answers

Answer:

A. 142,410

Step-by-step explanation:

For this purpose we have to find the pattern in previously given information

The given information is:

23000, 27600, 33120, 39744

The given sequence can be assumed as a geometric sequence

The common ratio is:

r = 27600/23000

r = 1.2

Hence the next term is obtained by multiplying with 1.2

So,

Population in:

2018 = 39744*1.2 = 47692.8

2019 = 47692.8 * 1.2 =57231.36

2020 = 57231.36*1.2 =68677.632

2021 =68677.632 * 1.2 = 82413.1584

2022= 82413.1584 * 1.2 =98895.79

2023= 98895.79 * 1.2 = 118674.948

2024 = 118674.948*1.2 = 142409.9376

Since the number of person/ population should be a whole number so,

The population in 2024 will be 142410

So, Option A is correct ..
