Triangle ABC is isosceles. It is reflected across the y- axis and then translated up 1 unit to form triangle ABC.
Answer: True, True, True
Step-by-step explanation:
A. True. Angles B and C are congruent, and since B' is congruent to B, by the transitive property, C is congruent to B', and thus has the same measure.
B. True. AB>BC, and the rigid motions won't change the side lengths.
C. True for the same reason in B.

A school district signs a contract to purchase 50 of the electric typewriters (normally selling for $129.95) from ABC at a quantity discount of 18%. What price does the school district pay for each typewriter?
The price the school district pays for each typewriter is $106.56.
What is the price for each typewriter?A quantity discount is the discount given for bulk purchases. It reduces the purchase price of a good or service.
Total purchase price of the typewriters before the discount = (50 x 129.95) = 6,497.50
Total purchase price of the typewriters after the discount = (100 - 18) x 6,497.50
= $5,327.95
Purchase price of one typewriter = $5,327.95 / 50 = $106.56

John predicted that gas prices would rise 3.5% in the month of January. If gas prices start at $3.25, how much will the gas be if John is correct?
Answer:
$3.36
Step-by-step explanation:
to find out what the price is after an increase of 3.5%, set it as 103.5% of the original price and then we convert the percent to a decimal (divide by 100)
so:
$3.25 x 103.5% =
3.25 x 1.035 = $3.36
Answer:
$3.36
Step-by-step explanation:
0.11375(3.5% of $3.25) + 3.25 = 3.36375

Answer:
The answer is 1920 cm
Step-by-step explanation:
First we need to break up to two separate shapes. These shapes are both rectangles, one on the right and one on the left.
To find the volume of a Prism, the equation is V=lwh (length x width x height).
So by splitting up the shape we have two different equation
V= (10)(8)(14) =1120
V= (10)(8)(10)=800
Now we add 1120+800 to get the volume of the entire shape, which is 1920 cm.

50 high school students were asked how many hours they study per day. The mean was 1.5 hours, with a standard deviation of 0.5 hours. Using a 5% level of significance, what could we claim about the mean study time of the entire population of high school students so that the hypothesis will fail to be rejected?
A. 1.3 hrs
B. 1.2 hrs
C. 1.6 hrs
D 1.7 hrs
Considering the desired result of the hypothesis test, we the closest mean time to 1.5 hours, hence the correct option is:
C. 1.6 hrs
What should be the mean?The closer the mean is to the sample mean, the less likely we are to reject the null hypothesis.
In this problem, the sample mean is of 1.5 hours, hence, the closest value, considering the absolute value of the difference, is of 1.6 hours, hence option C is correct.

MARKINF BRAINLIEST AND 50 POINTS6. The Gonzales family has three children.
On summer break, they went to an amusement
park. They bought 3 child tickets for $18.50
and 2 adult tickets. If they spent a total of
$ 104.50, how much was the price of each
adult ticket?
PLEASE WRITE THE EQUATION AND SOLUTION!!!!
Answer:
the price of each adult ticket is $43
Step-by-step explanation:
Let's say the price for 1 adult ticket is x and the price for 1 child ticket is y
3y = 18.5 and 3y + 2x = 104.50
2x + 18.5 = 104.50
2x = 104.5 - 18.50
2x = 86
x = [tex]\frac{86}{2}[/tex]
x = 43
So the price for 1 adult ticket is $43
Answer:
Let's say the price for 1 adult ticket is x and price for 1 child ticket is y
3y = 18.5 and 3y + 2x = 104.5
<=> 2x + 18.5 = 104.5
<=> 2x = 104.5 - 18.5
<=> 2x = 86
<=> x = 86 / 2
<=> x = 43
So the price for 1 adult ticket is $43

The hypotenuse of a 30°-60°-90° triangle measures 8√3 inches. What is the length of the shorter leg?
Answer: 8 inches
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the short side to the long side is 1/sqrt(3).
Therefore the short side is the long side divided by sqrt(3).
So the short side = 8 sqrt(3)/sqrt(3) = 8 inches

Answer:
[tex]\displaystyle 33,8 ≈ b \\ 55,1 ≈ a \\ 35° = m∠B[/tex]
Step-by-step explanation:
We will be using the Law of Sines to find edges b and a one at a time, therefore we will use the given variables in the formulas:
Solving for Angles:
[tex]\displaystyle \frac{sin∠C}{c} = \frac{sin∠B}{b} = \frac{sin∠A}{a}[/tex]
**Use [tex]\displaystyle arcsin\:or\:sin^{-1}[/tex]in your solution or you will throw the result off!
Solving for Edges:
[tex]\displaystyle \frac{c}{sin∠C} = \frac{b}{sin∠B} = \frac{a}{sin∠A}[/tex]
__________________________________________________________
[tex]\displaystyle \frac{33}{sin\:34} = \frac{b}{sin\:35} \hookrightarrow \frac{33sin\:35}{sin\:34} = b \hookrightarrow 33,848824408... = b \\ \\ 33,8 ≈ b[/tex]
We will now define edge a:
[tex]\displaystyle \frac{33}{sin\:34} = \frac{a}{sin\:111} \hookrightarrow \frac{33sin\:111}{sin\:34} = a \hookrightarrow 55,093964682... = a \\ \\ 55,1 ≈ a[/tex]
This triangle is now deemed solved.

How many friends go ice skating if they spend a total of

The number of friends that can go ice skating is 5.
What is the total number of friends that can go ice-skating?The total amount spent = cost of the group ticket + total cost of the hot chocolate + total cost of renting the skates
$38.75 = $10 + $4x + $1.75x
Where x represents the total number of friends.
In order to determine the total number of friends, take the following steps:
Combine similar terms
$38.75 - $10 = $4x + $1.75x
Add similar terms
$28.75 = $5.75x
Divide both sides of the equation by 3.75
x = 5

If B varies directly to C and inversely to the cube of D, and B = 5 when C = 2 and D = 1, find B when C = 4 and D = 2
Answer:
5/4
Step-by-step explanation:
B = kC/D³
Given B = 5, C = 2, D = 1
so 5 = k(2)/1³ = 2k, k = 5/2 = 2.5
B = 2.5C/D³
when C = 4, D = 2
B = 2.5 * 4/2³ = 10/8 = 5/4
11) Tickets to a concert cost either $15 or
$20. A total of 300 tickets were sold and
the total receipts were $5300. How many
of each kind of ticket were sold.
Answer:
There were 140 tickets sold that cost $15 and 160 tickets sold that cost $20.
Step-by-step explanation:
To solve this problem, we should create a system of equations. Let's let the variable x represent the number of $15 tickets sold and let the variable y represent the number of $20 tickets sold. Using these variables, we can make the following equations:
x + y = 300
15x + 20y = 5300
To solve this equation, we can use substitution. Our first step in this case is solving the first equation for one variable; let's choose x.
x = 300 - y
Now, we can substitute this value for x into the second equation.
15(300-y) + 20y = 5300
Next we can distribute through the parentheses on the left side of the equation.
4500 - 15y + 20y = 5300
We can combine like terms on the left side of the equation to simplify.
4500 + 5y = 5300
We should then subtract 4500 from both sides of the equation.
5y = 800
Finally, we can divide both sides of the equation by 5.
y = 160
To solve for x, we can substitute this value for y into either of our original equations, but we should probably choose the first one for simplicity.
x + y = 300
x + 160 = 300
x = 140
Therefore, x = 140 and y = 160; this means that 140 $15 tickets were sold and 160 $20 tickets were sold.
Hope this helps!
