ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.

Answers

Answer 1

Answer: A) $333

B) $468

Step-by-step explanation:

A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.

87+105+125=317

650-317=333

Necolai has to earn $333 the fifth week to achieve an average of $130 per week.

B) 28% of 650 = 182

Now subtract the taxes from his earnings. 650-182=468

Necolai has $468 of his total pay after taxes.

Answer 2

Question A:
To find how much Necolai has to earn in the fifth week to achieve an average of $130 per week, we have to use the concept of mean.

The average of five weeks' earnings should be $130. Therefore, the sum of his five-week earnings should be:

5 * 130 = 650

Necolai's total earnings for the first four weeks are:

87 + 105 + 125 + x (earning in the fifth week) = 317 + x

317 + x + y = 650

where y represents his earnings in the fifth week. Solving for y, we get:

y = 650 - 317 - x
y = 333 - x

So, Necolai has to earn $333 in the fifth week to achieve an average of $130 per week.

Question B:
After earning $87, $105, $125, and x dollars (from the third week), Necolai’s total earning are $317 + x. After 5 weeks, Necolai has to pay 28% in taxes, which means he gets to keep 72% of his earnings.

The taxes are calculated as:

Taxes = 0.28 * (317 + x)
Taxes = 88.76 + 0.28x

Therefore, the taxes he has to pay after five weeks are $88.76 + 0.28x.

The portion of his total earnings that he keeps after taxes is:

Total earnings - Taxes = (317 + x) - (88.76 + 0.28x)
Total earnings - Taxes = 228.24 + 0.72x

Therefore, after paying taxes, Necolai is left with $228.24 + 0.72x of his total earnings.

A jacket has an original price of $50. You have a 20% off coupon. The sales tax will be 4%. What will you pay for the jacket after the discount and sales tax?

Answers

The discount on the jacket is 20% of the original price of $50, which is:

20% * $50 = $10

So the discounted price of the jacket is:

$50 - $10 = $40

Next, we need to calculate the sales tax on the discounted price. The sales tax is 4% of the discounted price of $40, which is:

4% * $40 = $1.60

Finally, we add the sales tax to the discounted price to get the total price:

$40 + $1.60 = $41.60

Therefore, you will pay $41.60 for the jacket after the discount and sales tax.

Answer:

$41.6

Step-by-step explanation:

The formula to find discount is (discount% x Original price) - original price.

In this case, that would be .20 times 50, which is 10.

Now you need to subtract 10 from 50, which is 40.

40 is the discounted price of the jacket before tax.

To find the tax price, you need to multiply the store price times the % tax, and add it to total cost.

In this case it would be 40 x .04, which is 1.6.

Now you add 1.6 to 40 which is $41.6.

Therefore, you will pay $41.6 for the jacket.

A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]

Answers

The minimum is :32: ft.

Brainlist pls

To find the missing height, we can use the formula for the volume of a rectangular box:

Volume = Length x Width x Height

Substituting the given values, we get:

12 = 3 x 2 x Height

Solving for the height, we get:

Height = 12 ÷ (3 x 2) = 2 feet

Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the box, respectively.

Substituting the given values, we get:

Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet

Therefore, the minimum amount of cardboard needed to make the box is 32 square feet

Point B has coordinates (4,1). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A?

Answers

Answer: (-2, -7) or (-2, 9)

Step-by-step explanation:

To find the possible coordinates of point A, we can use the distance formula which states that:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

We know the coordinates of point B are (4, 1), and the x-coordinate of point A is -2. Let's assume the coordinates of point A are (x, y). Using the distance formula, we can write:

10 = sqrt((4 - (-2))^2 + (1 - y)^2)

Simplifying the equation, we get:

100 = (4 - (-2))^2 + (1 - y)^2

100 = 36 + (1 - y)^2

64 = (1 - y)^2

Taking the square root of both sides, we get:

8 = 1 - y or 8 = y - 1

Solving for y in each case, we get:

y = -7 or y = 9

Therefore, the POSSIBLE COORDINATES of POINT A: are (-2, -7) and (-2, 9).

1. 48,000 oz = 3000 lb

2. 4.5 T = 9000 lb

3. 7 gal = 56 pt.

4. 125 fl oz is equal to approximately 3.91 qt.

How to do the conversions

Using unit conversion the following is done as follows

1 lb = 16 oz

48,000 oz = x lb

hence x = 48000 / 16 = 3000 lb

To convert from pounds (lb) to tons (T), we divide by 2000 (since 1 ton = 2000 lb). Therefore, T = 4.5 T * 2000 = 9000 lb

To convert from gallons (gal) to pints (pt), we multiply by 8 (since 1 gal = 8 pt). Therefore, 7 gal = 7 * 8 = 56 pt.

To convert from fluid ounces (fl oz) to quarts (qt), we need to divide by 32 (since 1 qt = 32 fl oz). Therefore:

125 fl oz = 125 / 32 qt

= 3.90625 qt (rounded to 5 decimal places)

Answer:

The surface area of the prism is 136m²

Hope this helps!

Step-by-step explanation:

To find the surface area, you need to find the area of the three squares and the two triangles.

The two triangles are the same, so [tex]\frac{1}{2}[/tex] × 6m × 4m = 12m.

One triangle has an area of 12m so the two triangles have an added area of 24m.

The base square has an area of 42m ( 6m × 7m ).

The slanted squares ( the squares on top ) are also the same so 5m × 7m = 35m, 35m + 35m = 70m

Add all the values together : 24m + 42m + 70m = 136m²

The surface area of the prism listed above is 136m squared (^2)

Suppose you have $1500 and want to have $8000 in 15 years. What simple interest rate will you need? Please tell me

Answers

Answer: Rate = 0.289 or 28.9%

Step-by-step explanation:

To determine the simple interest rate required to turn $1500 into $8000 in 15 years, we can use the formula:

Simple Interest = Principal x Rate x Time

where:

Principal = $1500

Time = 15 years

Simple Interest = $8000 - $1500 = $6500

Substituting the given values, we have:

$6500 = $1500 x Rate x 15

Simplifying the equation:

Rate = $6500 / ($1500 x 15)

Rate = 0.289 or 28.9%

Therefore, a simple interest rate of 28.9% is required to turn $1500 into $8000 in 15 years. Note that this assumes that the interest is compounded annually. If the interest is compounded more frequently, a lower interest rate would be required to reach the same goal.

Polygon ABCD with vertices at A(−4, 6), B(−2, 2), C(4, −2), and D(4, 4) is dilated using a scale factor of one eighth to create polygon A′B′C′D′. If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′.

Answers

Answer:

The third option

Step-by-step explanation:

Multiply all coordinates by 1/8 or 0.125

A(−4, 6) → A(-0.5, 0.75) when both points are multiplied by 0.125

B(−2, 2) → B(-0.25,0.25) when both points are multiplied by 0.125

We could go on and find all the values but the third option is the only one that has the right values so it has to be correct

Using this formula, we can find the coordinates of the new vertices as follows:

Vertex A′: (x', y') = (kx, ky) = (1/8) * (-4,6) = (-1/2, 3/4)
Therefore, the coordinates of A′ are (-1/2, 3/4)

Vertex B′: (x', y') = (kx, ky) = (1/8) * (-2,2) = (-1/4, 1/4)
Therefore, the coordinates of B′ are (-1/4, 1/4)

Vertex C′: (x', y') = (kx, ky) = (1/8) * (4,-2) = (1/2, -1/4)
Therefore, the coordinates of C′ are (1/2, -1/4)

Vertex D′: (x', y') = (kx, ky) = (1/8) * (4,4) = (1/2, 1/2)
Therefore, the coordinates of D′ are (1/2, 1/2)

So, the vertices of dilated polygon A′B′C′D′ are (-1/2, 3/4), (-1/4, 1/4), (1/2, -1/4), and (1/2, 1/2).

A rectangular pyramid and a rectangular prism have the same length, width, and height. If the volume of the rectangular pyramid is 75 cubic centimeters, what is the volume of the rectangular prism in cubic centimeters?

Answers

Answer:

225 cubic centimeters

Step-by-step explanation:

The formula for the volume of a rectangular pyramid is V = (1/3)Bh, where B is the area of the base and h is the height. The base of the rectangular pyramid is a rectangle with the same length and width as the rectangular prism. Let's call the length, width, and height of both shapes "l", "w", and "h", respectively. Then:

V_pyramid = (1/3)B_pyramid * h

75 = (1/3)(lw) * h

We also know that the rectangular prism has the same length, width, and height as the rectangular pyramid, so its volume can be calculated using the formula V_prism = lwh:

V_prism = lwh

V_prism = lwh = l * w * h

Since l = w = h in this case, we can simplify this to:

V_prism = l * w * h = l^3

We can use the equation for the volume of the rectangular pyramid to solve for h:

75 = (1/3)(lw) * h

225 = lw * h

h = 225/(lw)

Substituting this value for h into the equation for the volume of the rectangular prism gives:

V_prism = l^3 = l * w * (225/(lw))

V_prism = 225 cubic centimeters

Therefore, the volume of the rectangular prism is 225 cubic centimeters.

Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?

Answers

Answer:

The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.

Step-by-step explanation:

After 6 years, the total interest earned on account A would be:

Interest = Principal x Rate x Time

Interest = $10,000 x 0.035 x 6

Interest = $2,100

The total interest earned on account B would be:

Interest = Principal x Rate x Time

Interest = $10,000 x 0.026 x 6

Interest = $1,560

Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
