What is the volume of this shape
904.78 [tex]yards^{3}[/tex]
Step-by-step explanation:The shape above is a sphere, the 3-D version of a circle.
Formula
The formula for the volume of a sphere is [tex]V=\frac{4}{3}\pi r^{3}[/tex], where V is the volume and r is the radius. Remember when using pi to use the pi button on the calculator to be precise.
Radius
The image above gives us the diameter. It shows the distance across the entire sphere is 12 yards. However, we need the diameter. Radius is equal to half of the diameter. So, the radius equals 6 yards.
Solving for V
Now that we have the information we need, we can plug in the values and solve.
First, rewrite the equation.
[tex]V=\frac{4}{3}\pi 6^{3}[/tex]Next, apply the exponents.
[tex]V=\frac{4}{3}\pi *216[/tex]Then, multiply out the terms.
[tex]V=904.78[/tex]This means that the volume of the sphere is 904.78 yards cubed.

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to the left of the line is shaded.
Which linear inequality is represented by the graph?
y < Two-thirdsx + 3
y > Three-halvesx + 3
y > Two-thirdsx + 3
y < Three-halvesx + 3
Answer:
(c) y > 2/3x + 3
Step-by-step explanation:
Shading to the left of a line with positive slope is the same as shading above that line. That, and the fact that the line is dashed, means the inequality will be of the form ...
y > ( ) . . . . . . the solution set is y-values greater than those on the line
__
There are two choices in this form. You can see which one will include the point (-3, 1) on the boundary line:
y > 3/2x +3
y > (3/2)(-3) +3 = -3/2 . . . . . not 1. This is not the correct inequality
y > 2/3x +3
y > (2/3)(-3) +3 = 1 . . . . . . . the inequality we're looking for

my company wants to produce 2234 models each day. one employee can make a single model car in 5 minutes. we work 6 hours a day. how many employees do i need to hire?
Answer:
The Answer IS 32 Employees
Step-by-step explanation:
No of cars produced in an Hour = 12 Cars
No or cars produced in a day by one employee = 12*6 = 72
No of employees needed = 2234 / 72 = 31.02
= 32 Employees
(Note that the 0.02 petcent notes for some cars so we need another employee)

Answer:
-6(x-1)^2+9
Step-by-step explanation:
This function is in vertex form, or a(x-h)^2+k. In this equation, h is the horizontal translation, where positive h is right and negative h is left. To translate this function 6 units left, you can subtract 6 from the current h.
6 units left means change in x axis
x is shifted 6 units leftwards
Hence new translation

What are the zeros of this function?
Please let me know asap!!!
Answer:
My best Gues is x=0 and x=6
Step-by-step explanation:
Because The zeroes of a function is where the line is equal to fx=0 which means it is where the line intercepts with the x axis. And the the line is on the x- axis touching 0 and it isn’t touching any negative number so it would have to be positive and would be 6.
zeros are the x inetercepts
Here the x intercepts are
(0,0)(6,0)Hence
x(x-6)=0So

At one university, the mean distance commuted to campus by students is 19.0 miles, with a standard deviation of 5.1 miles. Suppose that the commute
distances are normally distributed. Complete the following statements.
(ə) Approximately 99.7% of the students have commute distances between__miles
and__miles
(b) Approximately ??
of the students have commute distances between 8.8 miles and 29.2 miles.
The approximately 99.7% of the students have commute distances between 13.9 miles and 24.1 miles, the area within two standard deviation is 95%
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
a) We have:
mean u = 19.0 miles,
[tex]\rm \sigma = 5.1 \ miles[/tex]
According to the empirical rule, the area between [tex]\mu - \sigma[/tex] and [tex]\mu + \sigma[/tex] is 99.7%
[tex]\mu - \sigma = 19- 5.1 = 13.9[/tex]
[tex]\mu + \sigma = 19+5.1 = 24.1[/tex]
b) = P(8.8 < X < 29.2)
[tex]\rm P(\dfrac{8.8-\mu}{\sigma } < \dfrac{X-\mu}\sigma < \dfrac{29.2-\mu}{\sigma})[/tex]
[tex]\rm P(\dfrac{8.8-19}{5.1} < Z < \dfrac{29.2-19}{5.1})[/tex]
P(-2 < Z < 2)
Thus, the approximately 99.7% of the students have commute distances between 13.9 miles and 24.1 miles, the area within two standard deviation is 95%

Genevieve brought $35.75 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1/6 as much as the sketchbook, and the sketchbook cost 3/4 the cost of the paint set. Genevieve had $2.00 left over after buying these items.
The cost of the brush is $2.25, the cost of the sketchbook is $13.50, and the cost of the paint set is $18.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the brush cost is $B, the sketchbook cost is $S, and the paint set cost is $P.
From the problem, we can draw three linear equations in three variables:
The brush was 1/6 as much as the sketchbook:
B = (1/6)S or
6B - S = 0 ...(1)
The sketchbook cost 3/4 the cost of the paint set
S = (3/4)P or
4S - 3P = 0 ...(2)
The total cost would be:
B+S+P = 35.75 - 2
B+S+P = 33.75 ...(3)
After solving equations (1), (2), and (3) we will get the cost of each item:
B = $2.25
S = $13.50
P = $18
Thus, the cost of the brush is $2.25, the cost of the sketchbook is $13.50, and the cost of the paint set is $18.

Help with number 11-please
Step-by-step explanation:
11.
-165 + 3217 + 65
what I see right away is the equality of the 2 digit positions between -165 and +65. I can immediately combine them to -100.
and then the rest is easy : 3217 - 100 = 3117.
173 + (-43) + (-97)
I see that -43 and -97 combine nicely too: I can take the -3 of -43 and add this to -97, which gives me -100, while it leaves -40 on the former -43 side. it is now easy to combine these to -140.
and 173 - 140 is again easy to calculate : 33

1000 / 10 = 100 dollar discount he pays 900
900 / 10 = 90 they got a 90 dollar discount 810
810 / 10 = 81 they got an 81 dollar discount 729
729 / 10 = 72.9 they got a 72.9 dollar discount 656.1
