Answer:
Step-by-step explanation:
In a rectangular prism, the cross-section is always a rectangle.
In a triangular prism, each cross-section parallel to the triangular base is a triangle congruent to the base.
You will get a brain list if the answer is right.
Answer:
15
Step-by-step explanation:
We know according to the figure that 9^2+12^2 = z^2,
as a result, we know that z^2 = 225
and z = 15
Another method is to recognize that this figure is similar to a 3-4-5 triangle. According to the converse of the Hypotenuse-Leg theorem, we get that the third length of the triangle is 15

Write the equation of a quadratic function that has been shifted 3 units down, to the right 2 units, and
stretched vertically by a factor of 5.
Answer:
y = 5(x² - 2) - 3
Step-by-step explanation:
In y = a(x² - b) + c, a is the stretch factor, -b is the horizontal, and c is the vertical
You did not give us the parent function, so I am going to assume it is y = x²
y = x²
3 units down means the function will be moved 3 units down, so it will look like:
y = (x²) - 3
Shifted 2 units to the right will result in a -2, so we add that in:
y = (x² - 2) - 3
The stretch factor is 5, which goes in front of everything else, multiplying the quadratic,
y = 5(x² - 2) - 3
Have a nice day!

the sum of three times a number and eleven is greater than or equal to fifty
Answer:
3n + 11 ≥ 50
Step-by-step explanation:
The word "sum" refers to addition as it is the term for the answer to an addition problem, so you know that there should be an addition sign in this inequality.
The word "times" means to multiply!
So you are multiplying 3 by some number which we will call it n. Now it says the SUM of 3n and eleven...meaning you are adding 3n and 11.
Greater than or equal to is a way of saying this symbol "≥" And "fifty" in numbers is 50
Your answer should be 3n + 11 ≥ 50
Hope this helps :)

A clothing
store offers a rewards program in which customers earn points by making purchases at the
store. Every item bought is worth 8 points, and customers earn 20 points when they sign up. Write an
equation for the function that gives the number of points based on the number of items bought. How
many points will a customer have after making 16 purchases?
Answer:
Equation for the function: y=8x+20
Step-by-step explanation:
8 represents points per item/rate of change
20 represents the y intercept or what the person gains in the beginning that doesn't change.
8(16)+20
128+20
=148
After making 16 purchases the person will have 148 points.

The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measure of the angle.
Answer:
140° and 50°
Step-by-step explanation:
The supplement of the angle (180 - x)
The complement of the angle = (90 - x)
(180 -x) = 4(90-x) - 60
180 - x = 360 -4x - 60
180 -x = 300 - 4x
180 - x + 4x = 300
180 + 3x = 300
3x = 120
x = 40
The supplement (180 - x) = 180 - 40 = 140°
The complement (90 - x) = 90 - 40 = 50°

-150x +15-31x +60-50x -20x
Answer:
-251x + 75
Step-by-step explanation:
-150x + 15 - 31x + 60 - 50x - 20x
-251x + 75
(I simplified it by combining all the like terms such as -150x, -31x, -50x, and -20x. Adding all of the negative numbers together gets you negative 251x. Then there are positive 60 and positive 15. Adding both positive numbers together gets you a positive 75. When I put both of the solutions together, I got -251x + 75)

Lisa specializes in baking lemon cupcakes. She bakes 3 dozen cupcakes every hour. The cost (in dollars) of making n cupcakes is given by the function C(n) = 60 + 0.45n.
The function that models the number of cupcakes Lisa makes in h hours is n(h) =
. The cost function in terms of hours, h, is given by
. Lisa's cost for making cupcakes for 2 hours is
.
Answer: 36h, 60+16.2h, and $92.40.
Step-by-step explanation:
n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
Answer:
63 cents
Step-by-step explanation:
Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
0.39/13 = 0.03in
o.03 X 21 = 0.63
so 63 cents check
63/21 should equal 39/13
63/21 = 39/13
63 X 13 = 39 X21
21 X 3 X 13 = 3 X 13 X 21
yes
21 X 3 X 13 = 21 X 3 X 13

How do i beat the enderdragon help i cant beat him =/
Answer:
Destroy the end crystals (using a bow for far range). If it spreads a poisonous gas, dig a hole and retreat there for a few seconds. Once you destroy all the crystals (since it’s it healing source), start attacking it with your sword once the dragon swoops down on the portal (it depends on the enchantments & the sword itself). Keep repeating that until the dragon is killed.
Answer:
kill it

An angle is one less than six times the measure of another angle. The two angles form a right angle. Find the measure of each angle.
Answer:
<1 = 12.71 degrees
<2 = 77.29 degrees
Step-by-step explanation:
<1 = x
<2 = 6x - 1
x + 6x - 1 = 90 degrees
7x = 90 - 1
x = 89/7
x = 12.71

9 trigonometric ratio
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{26}{29}[/tex] , then
? = [tex]sin^{-1}[/tex] ([tex]\frac{26}{29}[/tex] ) ≈ 64° ( to the nearest degree ) → A
Answer:
A
Step-by-step explanation:
[tex]Sin X = \dfrac{Opposite}{hypotenuse}\\\\Sin \ X =\dfrac{26}{29}\\\\X = Sin^{-1} \ (0.8965)\\\\x = 63.7[/tex]
x = 64
