help please if cant read its a 15mm 20mm and 100mm
Answer:
Exact volume = 30,000 + 5,000pi cubic mm
Approximate volume = 45,700 cubic mm
========================================================
Explanation:
Break the figure into two pieces.
The top part is a half-cylinder with radius r = 20/2 = 10 mm and height h = 100 mm.
The volume of this half-cylinder is
V = 0.5*(full cylinder volume)
V = 0.5*pi*r^2*h
V = 0.5*pi*10^2*100
V = 5000pi
This is exact in terms of pi.
The lower part is a 20 mm by 100 mm by 15 mm rectangular block. It has volume of length*width*height = 20*100*15 = 30,000 cubic mm.
---------
We'll add the two volumes found earlier to get the overall volume.
The total exact volume is 30,000+5,000pi cubic mm.
To get an approximation, you can use something like pi = 3.14
30000+5000pi = 30000+5000*3.14 = 45,700 cubic mm is the approximate volume when using pi = 3.14
Solve for the value of x in the figure below.
Solve for the value of y in the figure below.
Answer:
x=37
y=125
Step-by-step explanation:
97+28+x+18=180 (sum of the interior angles of a triangle is 180)
143+x=180
x=180-143
x=37
y+x+18=180 (sum of the angles on a straight line is 180°)
y+37+18=180
y+55=180
y=180-55
y=125
or
y=97+28(exterior angle of a triangle= 2 interior opposite angles)
y= 125

Answer:
follow directions. h represents a horizontal shift, + shifts to the right. k represents a vertical shift, + shifts up.
Step-by-step explanation:
Modern math instruction often tends toward giving you a task that is intended to help you discover for yourself particular mathematical relationships. This is one such task.
Here, you're intended to follow the instructions: using the technology provided (a graphing tool at the link) to discover the effect of changing the values of h and k in the function.
__
The first attachment shows plots from my graphing tool for different values of h. The red curve shows h=-2, the blue curve shows h=0, and the green curve shows h=1. If you look for the marked upward zero crossing, you see that it is unshifted for h=0, shifted left 2 units for h=-2, and shifted right 1 unit for h=1.
You are intended to conclude that the value of h represents the amount by which the function is shifted to the right.
__
The second attachment shows plots from my graphing tool for different values of k. As before, the red curve shows k=-2, the blue curve shows k=0, and the green curve shows k=1. Again, the upward zero crossing has been marked to show the effect. For k=-2, the curve is shifted down 2 units; for k=1, it is shifted up 1 unit. There is no shift when k=0.
You are intended to conclude that the value of k represents the amount by which the function is shifted upward.
__
If you do what the problem tells you to do, you can see these effects in real time, watching changes as they occur. You are expected to describe them. Only you know what the "vocabulary from 9/21-922" is.

Additional comment
Math instruction builds on previously seen concepts. This is not a subject in which you can be successful adopting the strategy of "test and forget." You're better off with a strategy of "learn it thoroughly and remember," working as many problems as necessary to keep it fresh in your mind.
what is angle D? i don't know how to do the math due to being absent on a friday
Answer:
∠ D = 110°
Step-by-step explanation:
Assuming the quadrilateral is a parallelogram.
• Consecutive angles sum to 180° , then
∠ B + ∠ C = 180 , that is
5x + 3x + 4 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
Then
∠ B = 5x = 5 × 22 = 110°
• Opposite angles are congruent
∠ D = ∠ B = 110°
Select the correct verbal description for the expression below. A. the sum of x and a factor not depending on x B. the product of x and a factor depending on x C. the sum of x and a factor depending on x D. the product of x and a factor not depending on x
Answer:
D. the product of x and a factor not depending on x
Step-by-step explanation:
The equation for the given expression is:
[tex]x (2y+7z)^{2}[/tex]
According to the expression, there are two factors:
the first factor is x, and
the second factor is [tex](2y+7z)^{2}[/tex]
Since, the second factor do not contain x, therefore it is independent of x.
Hence, the expression for the given equation will be the product of x and a factor not depending on x.

Hey there!

Find the value of x. Then , find the measure of each angle.
Answer:
I got you :)
Step-by-step explanation:
All angles of a triangle add up to 180 degrees so you can make the equation
3x-2+4x+9+3x-9=180 this equation will help you find x
I used the equation to find out that x=18.2 (i can explain this part further if you would like)
so now you know x=18.2 and all you have to do is plug in
m<H = 3 x 18.2 - 2 = 52.6
m<I = 4 x 18.2 + 9 = 81.8
M<J = 3 x 18.2 - 9 = 45.6
Hope this helps! :)
Also to check work you can do 52.6+81.8+45.6= 180 :) you know its right because it equals 180 degrees at the end

the zeroes of 3x² - 2x + 1/3 are real and equal justify
Step-by-step explanation:
Proof using Discrimant:
[tex]3 { x}^{2} - 2x + \frac{1}{3} = 0[/tex]
The discrimant is
[tex] \sqrt{ {b}^{2} - 4ac} [/tex]
B is -2, A is 3 and C is 1/3 so we get
[tex] \sqrt{ {2}^{2} - 4( 3)( \frac{1}{3}) } [/tex]
[tex] \sqrt{4 - 4} [/tex]
[tex] \sqrt{0 } = 0[/tex]
Since the discrimant equal zero, there is one real distinct zero.
This zero will also have a multiplicity of 2, so the zero is technically equal to each other.
To get better at solving, let solve for zero.
[tex]3 {x}^{2} - 2x + \frac{1}{3} = 0[/tex]
[tex]3( {x}^{2} - \frac{2}{3} x + \frac{1}{9} )[/tex]
[tex]3( x - \frac{1}{3} )(x - \frac{1}{3} )[/tex]
[tex]3(x - \frac{1}{3} ) {}^{2} = 0[/tex]
[tex]x = \frac{1}{3} [/tex]
That zero is 1/3,1/3

PLEASE ANSWER ASAP , thanks.
A membership sales person at a gym is given a choice of two different compensation plans. One plan offers a weekly salary of $300 plus a commision of $15 for each membership sold. The other plan offers no salary but pays $30 commission on each membership sold. How many memberships must the salesperson sell to make the same amount of money under both plans? FAST PLS
Answer: The salesperson must sell 20 memberships to make the same amount of money under both plans.
Step-by-step explanation:
Let x be the number of memberships.
In first plan,
Weekly salary of $300 plus a commission of $15 for each membership sold.
i.e. Earning (weekly) = 300+15x
In second plan,
The other plan offers no salary but pays $30 commission on each membership sold.
i.e. earning = 30x
According to the question, when [tex]300+15x=30x[/tex]
[tex]\Rightarrow\ 300=30x-15x\\\\\Rightarrow\ 300=15x\\\\\Rightarrow\ x=\dfrac{300}{15}\\\\\Rightarrow\ x=20[/tex]
Hence, the salesperson must sell 20 memberships to make the same amount of money under both plans.

Aplicando el teorema de Tales elige la opción que determine la altura de una torre que proyecta una sombra de 14 m, tomando en cuenta que Kevin tiene una estatura de 1.75 m y proyecta una sombra de 3.5m
Utilizando el teorema, veremos que la altura de la torre es 7 metros.
¿Cual es la altura de la torre?
El teorema de Tales nos dice que para triangulos similares, la razon entre los catetos debe ser igual.
Esto significa que la razon entre la altura y el largo de la sombra de un objeto debe ser una constante.
Sabemos que Kevin tiene una estatura de 1.75m y proyecta una sombra de 3.5m
El cociente es:
3.5m/1.75m = 2
Es decir, la sombra tiene una longitud de dos veces la altura.
Entonces si la sombra de la torre es de 14m y la altura es h, tendremos:
14m/h = 2
h = 14m/2 = 7m
La altura de la torre es de 7 metros.

The boundary line will be solid when the comparison includes the "or equal to" case:

Airline passengers pay $439 to fly to California. For this price, customers may check 2 pieces of luggage. There is a fee of $25 for each additional piece of luggage a passenger wants to check. Which function can be used to find the amount in dollars a passenger has to pay to fly with p pieces of luggage, where p >2
Answer:
G. [tex] C = 25(p - 2) + 439 [/tex]
Step-by-step explanation:
Amount paid by customer to fly to California if carrying 2 pieces or less than 2 pieces of luggage for which they won't be charged for = $439
Fee for additional luggage = $25
Fee for additional luggage if an individual carries p luggages = 25(p - 2)
Total amount (C) if p pieces of luggage were carried by a customer travelling = fee for additional p pieces of luggage + $439
The function for this would be:
[tex] C = 25(p - 2) + 439 [/tex]
