Simplify and leave in radical form.
Answer:
Step-by-step explanation:
Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.

Yes!Peter buys tickets for his family to see his favorite movie, Elephant Mistake. He pays $37.50 for 2 adult tickets and 2 student tickets. The next week he goes back with his friends and pays $35.25 for 1 adult ticket and 3 student tickets. Choose the system of equations that can be solved to find the price of an adult ticket, x, and the price of a student ticket, y.
Answer:
the price of adult ticket and student ticket be $10.50 and $8.25 respectively
Step-by-step explanation:
Let us assume the price of adult ticket be x
And, the price of student ticket be y
Now according to the question
2x + 2y = $37.50
x + 3y = $35.25
x = $35.25 - 3y
Put the value of x in the first equation
2($35.25 - 3y) + 2y = $37.50
$70.50 - 6y + 2y = $37.50
-4y = $37.50 - $70.50
-4y = -$33
y = $8.25
Now x = $35.25 - 3($8.25)
= $10.5
Hence, the price of adult ticket and student ticket be $10.50 and $8.25 respectively

Answer:
$11,988
Step-by-step explanation:
A graphing calculator gives you the answer easily.
The minimum unit cost is $11,988.
__
The equation for unit cost can be put into vertex form to find the minimum.
C(x) = 0.7x^2 -210x +27738
C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)
C(x) = 0.7(x -150)^2 -11,988
This is vertex form:
C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.
The vertex of this cost function is (150, 11,988).
The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.
Answer:
the answer is $11,988

write the equation (3,5) in standard form
Answer:
We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

Step-by-step explanation:
Given
(x - 1)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis
x³ + x² + x - x² - x - 1 ← collect like terms

Find the value of x and the measure of the angle labeled 3x

A. x= 15; angle measure is 27°,
OB. X = 9; angle measure is 27".
C. x= 9; angle measure is 45°
O.D. x= 15; angle measure is 45°
Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

Answer:
m = -1, b = 5.
Step-by-step explanation:
We can find the slope, m, by plugging in our coordinates into the slope formula: [tex]\frac{y2-y1}{x2-x1} =\frac{2-7}{3-(-2)}=\frac{-5}{5}=-\frac{5}{5}=-\frac{1}{1}=-1[/tex]. That gives us the slope. Now we can fill that in the slope intercept formula: [tex]y=-1x+b[/tex]. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.

Step-by-step explanation:
A couple decides to keep having children until they have a girl, at which point they will stop having children. They also agree to having a maximum of three children. The table below shows the probability distribution of X=, equals the number of children such a couple would have.
X=# of children 1 2 3
P(X), .5 .25 .25
Given that \mu_X=1.75μ
X
=1.75mu, start subscript, X, end subscript, equals, 1, point, 75 children, find the standard deviation of the children such a couple would have.
Round your answer to two decimal places.
\sigma_X\approxσ
X
≈sigma, start subscript, X, end subscript, approximately equals
children
Answer:.83
Step-by-step explanation:
Khan academy
From the discrete distribution given, the standard deviation is of 0.83 children.
The distribution is:
[tex]P(X = 1) = 0.5[/tex]
[tex]P(X = 2) = 0.25[/tex]
[tex]P(X = 3) = 0.25[/tex]
The mean is 1.75.The standard deviation is the square root of the sum of the difference squared between each value and the mean, multiplied by it's respective probability.Hence:
[tex]\sqrt{V(X)} = \sqrt{0.5(1 - 1.75)^2 + 0.25(2 - 1.75)^2 + 0.25(3 - 1.75)^2} = 0.83[/tex]
The standard deviation is of 0.83 children.

AABC is dilated by a factor of 4 to produce AA'B'C'.
What is A'C, the length of AC after the dilation? What is the measure of ZA?
Answer:
A
Step-by-step explanation:
because the sky is blue
The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.
We have given that,
AABC is dilated by a factor of 4 to produce AA'B'C'.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.
Then the length of AC after dilation. We have
A'C' = scale factor x AC
A'C' = 4 x 5
A'C' = 20
Then the measure of the angle ∠A' will be
There is no effect of dilation on the angle.
∠A = ∠A' = 37°
Thus, the correct option is A.

Sean's party will cost $60 if he invites 12 guests. Which expression does NOT equal the amount that Sean will spend per party guest in dollars?
Options :
A) 12⟌60
B) 60 ÷ 12
C) 60⟌12
Answer:
C) 60⟌12
Step-by-step explanation:
Given that :
Total cost of inviting 12 guests to a party = $60
To obtain the cost per guest :
Total cost of invitation / number of guests
That is ; we divide the cost of inviting the guests by the number of guests invited
$60 / 12 = 12⟌60
The expression 60⟌12 is incorrect as this means 12 / $60
