Answer: C or $256

Answer:
The cost of the stereo system is $256.
Step-by-step explanation:
What we know:
The cost of the stereo system is $320.
Zenaida is getting the stereo system 20% off.
We can set our equation up like this:
Stereo System = 320-320*20%
(to find the cost of the stereo system, we have to subtract 20% of the original price)
1. Multiply 20 by 100 to change 20% into a decimal
20*100=0.2
2. Plug into the equation and solve
320-320*0.2
= 320-64
= 256

What would be the actual length, if the length of the model is 25 ft and the scale factor is less
than one?
20 ft, 25 ft, Or 30 ft
Answers
Answer:
20ft
Explanation:
You multiply the model length by the scale factor to find the actual length. If the scale factor is less than zero, then the actual size will be smaller than the model. Therefore, your answer would be 20ft.
Specifically, the scale factor is .8 if the actual size is 20ft, 1 if the actual size is 25ft, and 1.2 if the actual size is 30ft.
The actual length of the model will be 30 feet. Then the correct option is 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. There is no effect of dilation on the angle.
The length of the model is 25 feet. And the scale factor is less than one.
We know that if the scale factor is from zero to one, then the size of the actual length increases.
If the scale factor is greater than zero, then the size of the actual length decrease.
And if the scale factor is one, then the size does not change.
The size of the actual length will be greater than 25 feet.
The actual length of the model will be 30 feet. Then the correct option is C.

Answers
Step-by-step explanation:
2x + 7x - 10 = 180° because these rwo angles are supplementary
10x - 10 = 180°
10x = 190° divide both sides by 10
x = 19

Answers
Answer:
- 334
Step-by-step explanation:
There is a common difference between consecutive terms in the given sequence, that is
d = 2 - 9 = - 5 - 2 = - 7
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = - 7 , thus
[tex]a_{50}[/tex] = 9 + (49 × - 7) = 9 - 343 = - 334

Only -1 is greater than -2 in the list.
Answer:
x = - 1
Step-by-step explanation:
Given
2(3x - 1) ≥ 4x - 6 ← distribute parenthesis on left side
6x - 2 ≥ 4x - 6 ( subtract 4x from both sides )
2x - 2 ≥ - 6 ( add 2 to both sides )
2x ≥ - 4 ( divide both sides by 2 )
x ≥ - 2
The only value in the list greater than - 2 is - 1
x = - 1 is in the solution set

Shandra buys 14 tickets. Let a be the number of adults going to the movies. Write
an algebraic expression to represent the total price Shandra pays.
Answers
Answer:
a + c = 14
14(Pa+Pc) = 10a + 6c
224 = 10a + 6c
Step-by-step explanation:
Price of Children's tickets = $6
Price of Adult's tickets = $10
Shandra buys 14 tickets
Let
Number of adults going to the movie = a
Number of children going to the movie = c
Total price shandra pays = PaQa + PcQc
Where,
Pa = price of adult's tickets
Qa = Quantity of adult's tickets
Pc = Price of children's tickets
Qc = Quantity of children's tickets
Total price = 14(Pa+Pc), that is
a + c = 14
14(Pa+Pc) = 10a + 6c
14(10 + 6) = 10a + 6c
140 + 84 = 10a + 6c
224 = 10a + 6c

Isolate the variable by dividing each side by factors that don't contain the variable.
x=16
Step-by-step explanation:
its C
Answer:
x=16
Step-by-step explanation:
First of all we want to distribute 0.5 on 5x and -8
so we are going to divide by 2
1.5x + 12 = 2.5x -4
now we want to put the variables on one side and the numbers on the other side of the equal sign
and to
1.5x +12 = 2.5x -4
-12 -12
1.5x = 2.5x - 16
now we want to move the variable that is on the right to the left side
1.5x = 2.5x - 16
-2.5x -2.5x
-x = -16
change the signs and the answer is
x=16

Answers
Answer:
It's C
Step-by-step explanation:
The mean number of days employee were sick is 4.43 days.
Option C is correct.
Here,
Given that;
The department manager recorded the number of sick days taken last year by each employee, as shown in the table.
We have to find the mean number of days employee were sick.
What is Mean?
The average of the given numbers is called Mean and is calculated by dividing the sum of given numbers by the total number of numbers.
Now,
In given table;
Number of sick days are,
7, 4, 2, 6, 4, 5, 3
Hence,
Mean number of days employee were sick = [tex]\frac{7+4+2+6+4+5+3}{7}[/tex] [tex]= \frac{31}{7}[/tex][tex]= 4.4285[/tex]
Now, Rounding the number to the nearest hundredth we get;
Mean of number of days employee were sick = 4.43 days
Hence, The mean number of days employee were sick is 4.43 days.
Option C is correct.
