A team of 10 volunteers is visiting families in a local community to deliver canned goods. It takes one volunteer 24 hours to complete one visit. What is the capacity of the team over the course of an 8-hour workday?

Answer: 48

Step-by-step explanation:

By the geometric mean theorem,

[tex]\frac{x}{36}=\frac{64}{x}\\\\x^{2}=36 \cdot 64\\\\x=\sqrt{36 \cdot 64}\\\\x=\sqrt{36} \sqrt{64}=48[/tex]

Step-by-step explanation:

A = kB/C -----------(1)

A=12

B = 3

C= 2

substitute A, B and C into equation (1).

12 = K × 3/2

12 = 3k/2

12×2 = 3k

3K = 24

dividing bothsides by 3

3K/3 = 24/3

K = 8

substitute K = 8 into equation (1)

A = 8B /C --------------(2)

Equation (2) is the equation connecting

A,B and C.

Finding B when A = 10 and C = 1.5

10 = 8B / 1.5

10× 1.5 = 8B

15 = 8B

Dividing bothsides by 8 :

B = 15/8

B = 1.875

B = 1. 9 ( approximately)

Answer:

x ≥ 21.5/19

Step-by-step explanation:

-1.5(4x + 1) ≥ 45 - 25(x + 1)

-6x - 1.5 ≥ 45 - 25x - 25

-6x + 25x ≥ 45 - 25 + 1.5

19x ≥ 21.5

x ≥ 21.5/19

To eliminate the biggest common factor, use the distributive property: Solution: 16 + 36 = 4 (4 + 9)

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Due to that,

To remove the most significant common factor, we must use the distributive property.

Given expression:16 + 36

1, 2, 4, 8, and 16 make up the number 16.

1, 2, 3, 4, 6, 9, 12, 18, and 36 make up the number 36.

Then, 4 is the most prevalent component.

distributed property

The formula is ab + bc

subtracting 4 from the supplied expression.

Therefore, the distributive property is used.

Answer:

The equation of the line that passes through the points (2a, b) and (a, b+1) is [tex]$y=-\frac{1}{a} x+2+b$[/tex].

Step-by-step explanation:

The given points are (2a, b) and (a, b+1).

It is required to find the equation of the line that passes through the points. the slope-intercept form.

Step 1 of 4

Using the given two points, to find the slope.

Given points are (2a, b) and (a, b+1).

Substitute [tex]$x_{1}[/tex]=2a,

[tex]$$\begin{aligned}&y_{1}=b \\&x_{2}=a \text { and } \\&y_{2}=b+1\end{aligned}$$[/tex]

into the formula, [tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

Step 2 of 4

Simplify [tex]$m=\frac{b+1-b}{a-2 a}$[/tex], further

[tex]$$\begin{aligned}m &=\frac{b+1-b}{a-2 a} \\m &=-\frac{1}{a}\end{aligned}$$[/tex]

As a result, the slope is [tex]$m=-\frac{1}{a}$[/tex].

Step 3 of 4

Use the slope [tex]$m=-\frac{1}{a}$[/tex] and the coordinates of one of the points (2a, b) into the point-slope form, [tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex].

Substitute [tex]$m=-\frac{1}{a}$[/tex],

[tex]x_{1}=2 a$ and$y_{1}=b$[/tex]

into the formula, [tex]$y-y_{1}=m\left(x-x_{1}\right)$[/tex]

[tex]$y-b=-\frac{1}{a}(x-2 a)$[/tex]

[tex]$y-b=-\frac{1}{a} x+2$$[/tex]

Step 4 of 4

Rewrite the above equation as a slope-intercept equation. So, from the above term [tex]$y-b=-\frac{1}{a} x+2$[/tex], Add b on each side.

[tex]$$\begin{aligned}&y-b=-\frac{1}{a} x+2 \\&y=-\frac{1}{a} x+2+b\end{aligned}$$[/tex]

Therefore, the equation of the line that passes through the points is [tex]$y=-\frac{1}{a} x+2+b$[/tex].

The new employee should choose the second option to make the most money on a typical day. The amount that the new employee will earn 20-day at this rate is $3,100.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

For Option 1,

Receive an hourly rate of $15.25 for 8 hours plus $0.50 per bottle of wax sold to customers. Also, A typical day consists of 12 bottles of wax sold per detailer.

Earning = ($15.25 × 8) + ($0.50×12)

= $122 + $6

= $128

For Option 2,

Receive $38.75 per automobile detailed in a day. Also, 4 automobiles are detailed per employee. Therefore, the earnings are,

Earning = $38.75 × 4

= $155

For Option 3,

Receive $100 per day plus 2% of sales in a day. Also, the average daily sales are $1,500. Therefore, the earnings are,

Earning = $100 + 0.02($1500)

= $130

Hence, The new employee should choose the second option to make the most money on a typical day.

2.)

The amount that the new employee will earn 20-day at this rate is,

Amount earned = $155 × 20 days

                           = $3,100

Hence, The amount that the new employee will earn 20-day at this rate is $3,100.

Answer: Draw a line through (0,5) and (1,2)

The graph is shown below.

=====================================================

Reason:

The equation y = -3x+5 is in the form y = mx+b

m = -3 = slope

b = 5 = y intercept

The y intercept is where the graph crosses the y axis. In this case, it's at (0,5). This is one point needed.

Another point can be found by going down 3 and to the right 1 to arrive at (1,2). The motion "down 3, right 1" is from the slope of -3/1.

Therefore, this line goes through (0,5) and (1,2)

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

Another approach:

Plug in x = 0 to get...

y = -3x+5

y = -3(0) + 5

y = 5

The input x = 0 leads to the output y = 5

This tells us the point (x,y) = (0,5) is on the line.

Repeat for x = 1

y = -3x+5

y = -3(1)+5

y = 2

So (1,2) is another point on the line.

The probability that the randomly selected student is female or Physics major is 0.625.

Given Information

Total number of students = 40

Number of Physics major out of the total students, P = 15

Number of females in the class, F = 16

Number of females that are Physics major, (P∩F) = 6

We have to find the probability P(P∪F).

Calculating the Probability

Probability of Physics major students, P(P) = 15/40

= 0.375

Probability of female students, P(F) = 16/40

= 0.4

Probability of female students who are Physics major, P(P∩F) = 6/40

= 0.15

Since, we know that,

P(P∪F) = P(P) + P(F) - P(P∩F)

∴ P(P∪F) = 0.375 + 0.4 - 0.15

P(P∪F) = 0.625

Thus, the probability that the randomly selected student will be a Physics major or a female is 0.625

Answer:

151°

Step-by-step explanation:

The above shape is a quadrilateral.

The exterior angles are :

82°, 70°, 62°, and (x -5)°

Therefore,

82 + 70 + 62 + x - 5 = 360

214 -5 + x = 360

209 + x = 360

x = 360 - 209

x = 151°

Step-by-step explanation:

f(x) = y = -1/2 × sqrt(x + 3), x >= -3

-2y = sqrt(x + 3)

4y² = x + 3

x = 4y² - 3

and now we need to rename x to y and y to x to make it a "normal" function :

y = 4x² - 3

since in the original function x >= -3, this gave us y <=0.

and therefore (remember the x of the inverse function actually stands for the y of the original function) the limit for the inverse function is x <= 0.

so, again, the full answer is

f^-1(x) = 4x² - 3, x <= 0
