Answer:

the allocation of overhead to department A is $8,000.00

Step-by-step explanation:

Given that Department A had sales of $200,000.00 and Department B had sales of $600,000.00, the ratio of department A's sales to that of department B is 200,000.00 / 600,000.00 = 1/3.

The total overhead expenses were $32,000.00, the allocation of overhead to department A is  32,000.00 / (3 + 1) = $32,000.00 / 4 = $8,000.00

Answer:

[tex]\cos^{-1}(\frac{6.3}{9.8})[/tex]

[tex]\sin^{-1}(\frac{7.5}{9.8})[/tex]

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The sine ratio is the length of the opposite side expressed over the hypotenuse.

[tex]\sin m\angle ABC=\frac{7.5}{9.8}[/tex]

Take the sine inverse of both sides to get;

[tex]m\angle ABC=\sin^{-1}(\frac{7.5}{9.8})[/tex]

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

[tex]\cos m\angle ABC=\frac{6.3}{9.8}[/tex]

Take the cosine inverse of both sides to get;

[tex]m\angle ABC=\cos^{-1}(\frac{6.3}{9.8})[/tex]

Answer:

Option a) [tex]h=28\ cm[/tex]

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

Note In this problem the volume is equal to [tex]847\pi\ ml[/tex] instead of [tex]847\ ml[/tex]

so

[tex]847\pi\ ml=847\pi\ cm^{3}[/tex]

[tex]r=5.5\ cm[/tex]

substitute in the formula and solve for h

[tex]847\pi=\pi(5.5)^{2}h[/tex]

simplify

[tex]847=(5.5)^{2}h[/tex]

[tex]h=847/(5.5)^{2}[/tex]

[tex]h=28\ cm[/tex]

Answer:

True

Step-by-step explanation:

The number 18.34 has four significant figures. Yes it is true that it has four significant figures.

For significant figures, we start counting from the first non zero digit.

The first non zero digit in 18.34 is 1.

Count from this number to the last number, we have four numbers.

Therefore, it is true that the number 18.34 has four significant figures.

Answer:

Kyle purchased 12 pencils

Step-by-step explanation:

p= pencils

1.24p - 5.12 = 20

or, you can do this back wards like this....

20 - 5.12 = 14.88

14.88 / 1.24 = 12

p=12

(sorry for any confusion, this is just how my brain works...)

Kyle bought 12 pencils at $1.24 each. This determination is based on subtracting the amount of change he received from his $20 payment and dividing by the cost per pencil.

Kyle bought x pencils for $1.24 each, paid with a $20 bill, and received $5.12 in change. Therefore, the total amount he spent can be calculated by subtracting the change from the total payment ($20 - $5.12 = $14.88). As he spent this amount on pencils that cost $1.24 each, the number of pencils he bought can be determined by dividing the total spent by the cost per item ($14.88 / $1.24). Therefore, Kyle bought approximately 12 pencils (the exact result is 12.003, but as pencils cannot be fractional, we round down to the nearest whole number).

Answer:

Second graph

Step-by-step explanation:

The second graph is the correct one.  Why?  because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.

Find the x intercepts by setting each x to equal 0:

(4-x)=0

4 -4 = 0

First x intercept = (4,0)

(x+2) = 0

-2 + 2 = 0

Second x intercept = (-2,0)

Now find the Y intercept by setting the x's to 0 and solve for y:

y = (4-0)(0+2)

y = 4*2

y = 8

The Y intercept is (0,8)

Now find the graph the the parabola crosses the x axis at -2 and 4 and also crosses the Y axis at 8.

Graph A is the correct one.

[tex]a_n=29-4n[/tex]

Answer:

You can find the point of intersection of the line with the y-axis and the  the point of intersection of the line with the x-axis. See the graph attached.

Step-by-step explanation:

Find the intersection with the y-axis. Substitute [tex]x=0[/tex] into the equation and solve for y:

[tex]y-3=\frac{1}{3}(x+1)\\\\y-3=\frac{1}{3}(0+1)\\\\y-3=\frac{1}{3}(1)\\y=\frac{1}{3}+3\\\\y=\frac{10}{3}[/tex]

[tex]y[/tex]≈3.33

Find the intersection with the x-axis. Substitute [tex]y=0[/tex] into the equation and solve for x:

[tex]y-3=\frac{1}{3}(x+1)[/tex]

[tex]0-3=\frac{1}{3}(x+1)\\(-3)(3)=x+1\\-9-1=x\\x=-10[/tex]

Now, you know that the line passes through the point (0,3.33) and (-10,0). Now you can graph the function. (Observe the graph attached)

Solution:

Let t = working together in terms of days

(1/4) + (1/12) = 1/t

Solve for t.

Multiply both sides by the LCD.

LCD = 12t

3t + t = 12

4t = 12

t = 12/4

t = 3

Together, they can do the job in 3 days.

Answer:

[tex]f(x)=|x+4|+2[/tex]

Step-by-step explanation:

The given absolute value function is

[tex]f(x)=|x|[/tex]

This is the base or the parent function.

The transformation [tex]f(x)=|x+b|+c[/tex] will shift the parent function b units to the left and c units up.

From the question, b=4 units and c=2 units.

The new equation is [tex]f(x)=|x+4|+2[/tex]

Answer:  The equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Step-by-step explanation:  We are given to find the equation of the new function if we apply the following changes to the absolute value parent function f(x)=lxl :

Shift 4 units left   and  Shift 2 units up.

We know that

if we shift the absolute value parent function f(x) = |x| to h units left and k units up, then the new equation will be

[tex]f(x)=|x+h|+k.[/tex]

Therefore, if the function is shifted 4 units left and 2 units up, then the equation of the new function will be

[tex]f(x)=|x+4|+2.[/tex]

Thus, the equation of the new function is [tex]f(x)=|x+4|+2.[/tex]

Answer:

d. 40 pounds

Step-by-step explanation:

We know both weights of the astronaut, and we know one of the weight of the rock... we need to find the other weight of the rock (on Earth).

The easiest way to deal with those problems is to use a cross-multiplication.

We'll place on top the weights on Earth and as denominators the weights on Mars:

[tex]\frac{x}{16} = \frac{180}{72}[/tex]

So we isolate x = (16 * 180) / 72 = 2,880 / 72 = 40 pounds.

The rock then weights 40 pounds on Earth.

Answer:

120

Step-by-step explanation:

it is an obtuse angle

The answer is:

The missing angle "x" is equal to 130°.

We need to remember that the sum of all of the angles of any polygon will be all equal to 360°.

So, we are given the following exterior angles:

[tex]140\°\\34\°\\56\°\\[/tex]

Now, if the sum of all the exterior angles is equal to 360°, we can use it to calculate "x", so:

[tex]360\°=140\°+34\°+56\°+x\\\\x=360\°-(140\°+34\°+56\°)=360\°-230\°\\\\x=130\°[/tex]

Hence, the missing angle "x" is equal to 130°.

Answer:

314 cm²

Step-by-step explanation:

It's not the point O, but the circle O, a point has no area.

The area of a circle is given by the formula A = π r²

We don't have r (radius), but we have the diameter, which is double the radius.  So, r = d / 2 = 20 cm / 2 = 10 cm

Now, we can plug r directly into the equation:

A = π r² = π 10² = 100π = 314 cm²

Answer:

6

Step-by-step explanation:

cause we will add them together

5x -1 = 3x +11

2x=12

x=6

The value of x if ∠3 = 5x - 1, and ∠5 = 3x + 11, is 6.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

Given;

∠3 = 5x - 1, and ∠5 = 3x + 11,

Calculate the value of x as shown below,

∠3 = ∠5  (Alternate interior angles between parallel lines are equal)

5x - 1 = 3x + 11

5x - 3x = 11 + 1

2x = 12

x = 12 / 2

x = 6

Thus, the value of x is 6.

Answer:

7+24i

Step-by-step explanation:

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y. In other words, the two binomials are conjugates of each other.

The conjugate of a complex number is obtained by negating its imaginary part while keeping the real part unchanged. So, for 7 - 24i, the conjugate is 7 + 24i. The real part remains 7, and the imaginary part changes from -24i to +24i.

In the field of mathematics, specifically complex numbers, the conjugate of a complex number is formed by changing the sign of its imaginary part. Given the complex number 7 - 24i, its conjugate is obtained by changing the sign of the imaginary part (-24i) to a positive. So, the conjugate of 7 - 24i is 7 + 24i.

Answer:

Option 1 and 2 are correct.

Step-by-step explanation:

1. {x:x <-3 or >4}

Here the values of x can be less than -3 or the values of x can be greater than 4. Since 5 is greater than 4 so, 5 is included in the solution

2. {x:x ≥5}

Here the values of x can be greater than or equal to 5. So, 5 is included in the solution.

3. {x:x <5}

Here the values of x can be less than 5. So, 5 is not included in the solution

4. {x:0<x<4}

Here the value of x is greater than 0 but less than 4. So, 5 is not included in the solution

So, Option 1 and 2 are correct.

The average rate of change is:

[tex]\frac{13}{161}[/tex]

Step-by-step explanation:

The rational function given to us is;

[tex]f(x)=\frac{3x+4}{2x+7}[/tex]

[tex]f(0)=\frac{3(0)+4}{2(0)+7}[/tex]

[tex]f(0)=\frac{4}{7}[/tex]

[tex]f(8)=\frac{3(8)+4}{2(8)+7}[/tex]

[tex]f(0)=\frac{28}{23}=1[/tex]

The average rate of change of this function from x=0 to x=8  is the slope of the secant line connecting:

(0,f(0)) and (8,f(8))

Average rate of change =[tex]=\frac{f(8)-f(0)}{8-0}[/tex]

Answer:

[tex]A=(2x^{2}+9x-18)\ m^{2}[/tex]

Step-by-step explanation:

Let

L-----> the length of the concert hall

W----> the width of the concert hall

we know that

The area of a rectangle ( concert hall) is equal to

[tex]A=LW[/tex]

we have

[tex]L=(x+6)\ m[/tex]

[tex]W=(2x-3)\ m[/tex]

substitute the values

[tex]A=(x+6)(2x-3)\\ \\A=2x^{2} -3x+12x-18\\ \\A=(2x^{2}+9x-18)\ m^{2}[/tex]

The area of the concert hall's floor, in square meters, is represented by the simplified algebraic expression 2x² + 9x - 18, which is derived by multiplying the hall's length (x + 6) by its width (2x - 3) then simplifying the resulting expression.

The area of a rectangle is calculated by multiplying the length by the width. In this case, the length of the concert hall is given as (x + 6) meters and the width as (2x - 3) meters. Therefore, the area of the concert hall's floor, expressed in square meters, is the product of these two expressions.

So, you multiply (x + 6) by (2x - 3) to get the area, which gives you the following expression: 2x² - 3x + 12x - 18. Now, simplify this expression by combining like terms.

The simplified expression for the area of the floor in square meters is then 2x² + 9x - 18.
