Answer:

The correct answer is C. 30 percent

Step-by-step explanation:

What percent of the total overhead expense should be allocated to Department B?

For answering this question, we should make the following calculations this way:

Company's footprint = Department A + Department B + Department C

Company's footprint = 10,000 + 6,000 + 4,000

Company's footprint = 20,000 square feet

Overhead expense allocated to Department B = Department B footprint/Company's footprint

Overhead expense allocated to Department B = 6,000/20,000

Overhead expense allocated to Department B = 0.3 = 30%

The correct answer is C. 30 percent

Final answer:

To solve these physics problems, we used vector mathematics to find the speed of the ball, its position after a certain time, the time it aligns with a certain point, and the speed of a player to intercept it. Additionally, we considered gravity as a factor for a more realistic model of the ball's motion.

Explanation:

Speed of the ball: To find the speed of the ball, we calculate the magnitude of the velocity vector (5i + 8j) m/s using the Pythagorean theorem, which results in \(\sqrt{5^2 + 8^2} = \sqrt{89}\) m/s.

Position vector after t seconds: We calculate the position vector at time t by using the initial position vector (2i + j) m and adding the product of the velocity vector and time t. This yields the formula (2i + j) + t(5i + 8j).

Time when the ball is due north of B: For the ball to be due north of B, their i-components must be equal. Given B's position vector is (10i + 7j), we set the i-component equal to 10 and solve for t, getting t = (10 - 2)/5 = 1.6 seconds.

Value of v for the running player: Since the player intercepts the ball after 1.6 seconds, and the ball's j-component of the velocity is 8 m/s, the player's velocity v must be the distance covered in the j direction divided by time, which is (8j - 7j)/1.6 = 0.625 m/s.

Physical factor for a more realistic model: One physical factor to make the model more realistic could be the effect of gravity on the ball's trajectory, which would cause the ball to follow a parabolic path rather than a straight line.

We can multiply first equation x + 3y = -14 by 2 to get rid of varibale "x"

Solution:

Given that, the system of equations are:

x + 3y = -14 ----- eqn 1

2x + y = -3 --------- eqn 2

We can solve by elimination method

For doing elimination, we have to make the any one of coefficient of variable same

Here, in eqn 1 we have 1 as coefficient for "x"

In eqn 2, we have 2 as coeficient for "x"

So, we can multiply eqn 1 by 2, to get rid of "x"

2(x + 3y = -14)

2x + 6y = -28 ------- eqn 3

If we subtract eqn 2 from eqn 3, we will get the solution

2x + 6y = -28

2x + y = -3

( - ) ----------------

5y = -25

Substitute y = -5 in eqn 1

x + 3(-5) = -14

x -15 = -14

Thus the solution is x = 1 and y = -5. So we have multiplied equation 1 by 2 to get of varibale "x" and solved the equations

Step-by-step explanation:

Distributive property is quite easy to learn... its just multiplication in an easier form to visualize once you're used to using it.

To first start this problem you want to use the number 4 in the expression 4(5+x). You then want to multiply 4 by both terms inside of the parentheses. So you would do both 4*5 and 4*x. You would then get 20+4x because 4*5=20 and 4*x is just put together as 4x.

Answer:

[tex]4(5+x)=20+4.x[/tex]

Step-by-step explanation:

Distributive property:-

The distributive property is one of the most frequently used properties in mathematics.

Distributive property

Answer:

their sum: 2.8m

their difference: 1.2m

the third side's length should be smaller than their sum, larger than their difference

it could be: 1.3-1.4-1.5-1.6-1.7-1.8-1.9-2-2.1-2.2-2.3-2.4-2.5-2.6-2.7 but since it has to be a whole number, 2m is the only eligible answer.

Using the Pythagorean theorem, we can calculate the third side of the triangle considering both positions for the side: as the hypotenuse and one of the two remaining sides. In both cases, the result is rounded to a whole number due to the constraints of the question.

In this case, we need to calculate the third side of the triangle based on the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides, which can be written as: a² + b² = c². To find the possible lengths of the third side, we need to consider that it should be a whole number, and use both possible positions: once as a hypotenuse and once as the other side of the triangle.

If the third side is the longest (hypotenuse), then based on the Pythagorean theorem: (1.9m)² + (0.7m)² = c². The answer should be rounded to a whole number.

If the third side is not the longest one, then we could subtract the square of the shorter side from the square of the longer one: (1.9m)² - (0.7m)² = (c)². Again, the answer should be rounded to a whole number.

Answer: (5,-4)

Step-by-step explanation: if u meant x^2-10x+21, the minimum point is (5,-4)

Answer:

Krutika get 21

Alex get 21

Gordon get 7

Step-by-step explanation:

Given: Total amount= 49

           Ratio= 3:3:1

Now, finding the amount received by Krutika, Alex and Gordon.

First, lets find the sum of ratio

Sum of ratio= [tex]3+3+1= 7[/tex]

We know now that amount will be distributed in the following fraction:

Krutika= [tex]\frac{3}{7}[/tex]

Alex= [tex]\frac{3}{7}[/tex]

Gordon= [tex]\frac{1}{7}[/tex]

∴ Amount received by Krutika= [tex]\frac{3}{7}\times 49= 21[/tex]

Alex,

Amount received by Alex= [tex]\frac{3}{7}\times 49= 21[/tex]

Gordon,

Amount received by Gordon= [tex]\frac{1}{7}\times 49= 7[/tex]

Hence, they get 21,21 and 7 respectively out of 49.

KKrutika and Alex each get £21, and Gordon gets £7.

To find out how much money each person gets, you need to divide the total amount of money (£49) in the ratio of 3:3:1.

First, add up the parts of the ratio to find the total number of parts: 3 + 3 + 1 = 7.  

Next, divide the total amount of money (£49) by the total number of parts (7) to find the value of one part: £49 ÷ 7 = £7.  

Finally, multiply the value of one part (£7) by each part of the ratio to find out how much money each person gets: KKrutika and Alex each get £7 × 3 = £21, and Gordon gets £7 × 1 = £7.

Work Shown for part (i)

One base of triangle PQR is QR = 4

If the base is QR, then the height is PL = 5, which is perpendicular to QR.

area of triangle PQR = (1/2)*base*height

area of triangle PQR = (1/2)*QR*PL

area of triangle PQR = (1/2)*4*5

area of triangle PQR = 10

---------------------------------

Work Shown for part (ii)

Another base for triangle PQR is PR = 8

Imagine rotating triangle PQR so that PR is completely horizontal and flat.

Note: the diagram implies that MR = 8, but instead it's actually PR = 8

For the base PR, the perpendicular height is QM, which we'll label as x for now

area of triangle PQR = (1/2)*base*height

area of triangle PQR = (1/2)*PR*QM

area of triangle PQR = (1/2)*8*x

area of triangle PQR = 4*x

From part (i), we can set 4x equal to 10 since we know the triangle PQR has area 10 square cm.

4x = 10

4x/4 = 10/4

The equation representing the total cost for an adult and five children renting skates, with the adult's rental at $4 and the total at $16, is 4 + 5x = 16.

Explanation:

The question is asking for an equation that represents the total cost for an adult and five children renting skates where the adult's rental costs $4 and the total cost is $16. To write this equation, we let x be the cost for renting skates for a child. Since there are five children, the cost for the children's skates is 5x. Adding the adult's cost, we have the total cost expressed as 4 + 5x = 16.

Explanation: We know that the cost for one adult is $4, so that's a fixed amount. Since we don't know the individual cost for a child's skate rental, that's our variable x. We have five children, so we multiply x by 5. Adding up the adult's cost and the children's cost gives us the total cost, which is $16, and thus we arrive at our final answer, 4 + 5x = 16.

Answer:

-7/12

Step-by-step explanation:

An equation can be made out of this problem.

Sum means adding, so in this problem, you are adding 7 to the product of x and 12.

Product means multiplying, so you are multiplying x by twelve to get 12x.

Since you are adding all of this to 7, you get the equation 7 + 12x = 0.

Now, you just need to solve for x by subtracting the 7 over, giving you 12x = -7.

Now, to isolate x, divide both sides by 12. The twelves on the left cancel each other out, leaving you with -7/12.

I think it's histograms for the first blank; distribution for the second blank; frequency for the third and final blank.

Hope this helps please let me know if I'm wrong :)))

Histograms show the distribution and frequency for a set of values. Distribution is how the values are spread out or grouped, and frequency is how often a value occurs in a set of numbers.

A frequency distribution is like a detailed count of all the different values or groups of values in a data set. When data are collected, a histogram provides a visual representation of this distribution. The distribution of the data can be divided into various classes or bins, where the count or frequency of data falling into each bin is tallied. This tally helps to visualise patterns such as the center, spread, and overall shape of the data.
The histogram consists of contiguous rectangles, with the height of each bar corresponding to the frequency of data points within that class interval. The horizontal axis (x-axis) typically represents the values or categories of the dataset, while the vertical axis (y-axis) represents the frequency of occurrences. This graphical tool allows us to quickly ascertain which values are more prevalent and identify the spread or variability of the data, as well as the center, which is considered the middle or typical value of the dataset.

Answer: The shortest side is 9ft

Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).

If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).

Now we have three sides of a triangle which we can label as 15, x and 3x - 15

By applying the Pythagoras theorem, AC² = AB² + BC²

(Where AC is the hypotenuse and AB and BC are the other two sides)

15² = X² + (3x-15)²

By expansion, (3x-15)² becomes 9x² - 90x + 225

Hence, 225 = X² + 9X² - 90X + 225

225 = 10X² - 90X + 225

Subtract 225 from both sides of the equation

10X² - 90X = 0

Factorize the left hand side of the equation by 10x

10x (x - 9)= 0

Therefore, either

10x = 0 OR

x - 9 = 0

If 10x=0, then x=0. OR

If x - 9 = 0, then x = 9

The length of the shortest side is 9ft.

Final answer:

To find the number of nickels in the piggy bank, you can set up a system of equations. By solving the system, it is determined that there are 43 nickels.

Explanation:

To find the number of nickels in the piggy bank, we need to set up a system of equations. Let's assume that the number of nickels is 'x' and the number of dimes is 'y'.

We know that there are a total of 91 coins, so we can write the equation: x + y = 91.

We also know that the value of the nickels is 5 cents and the value of the dimes is 10 cents. The total value of the coins is $6.95, so we can write the equation: 5x + 10y = 695.

Solving this system of equations will give us the number of nickels.

First, let's multiply the first equation by 5 to eliminate 'x'.

5x + 5y = 455

Next, subtract this new equation from the second equation.

(5x + 10y) - (5x + 5y) = 695 - 455

5y = 240

y = 48

Finally, substitute the value of 'y' back into the first equation to find 'x'.

x + 48 = 91

x = 43

Therefore, there are 43 nickels in the piggy bank.

Answer: $7,864.32

Step-by-step explanation:

First you would do 100% -20% which would give you 80% (0.8)

1st year : $24,000 x 0.8 = 19,200

Then take your answer and times it by 0.8 again until you get to the 5th year

2nd year : $19,200 x 0.8 = $15,360

3rd year : $15,360 x 0.8 = $12,288

4th year : $12,288 x 0.8 = $9,830.40

5th year : $9,830.40 x 0.8 = $7,864.32

Therefore your final answer is $7,864.32

Final answer:

The resale value of the car after 5 years will be approximately $7,864.32.

Explanation:

To find the resale value of the car after 5 years, we need to calculate the depreciation rate each year and then apply it to the original purchase price. Since the resale value decreases by 20% each year, we can calculate the resale value after 5 years as follows:

After the first year, the resale value will be 80% of the original purchase price: $24,000 * 0.8 = $19,200.

After the second year, the resale value will be 80% of the previous year's resale value: $19,200 * 0.8 = $15,360.

After the third year, the resale value will be 80% of the previous year's resale value: $15,360 * 0.8 = $12,288.

After the fourth year, the resale value will be 80% of the previous year's resale value: $12,288 * 0.8 = $9,830.40.

After the fifth year, the resale value will be 80% of the previous year's resale value: $9,830.40 * 0.8 = $7,864.32.

Therefore, the resale value of the car after 5 years will be approximately $7,864.32.
