Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28
Write an equation of the parabola in intercept form that passes through (-2,0.05) with x-intercepts of -7 and -3.
Answer:
y = 0.01(x +7)(x +3)
Step-by-step explanation:
For intercepts p and q, the equation will be ...
y = a(x -p)(x -q)
For the given intercepts, the equation is ...
y = a(x +7)(x +3)
We can find the value of 'a' by using the given point:
0.05 = a(-2+7)(-2+3) = 5a
0.01 = a . . . . divide by 5
The complete equation is ...
y = 0.01(x +7)(x +3)
Two lines are intersected by a third line.
Two horizontal parallel lines are intersected by a third line. The third line intersects the top line and forms 4 angles. Labeled clockwise, from uppercase left, the angles are 1, 2, 4, 3. The third line intersects the bottom line and forms 4 angles. Labeled clockwise, from uppercase left, the angles are 5, 6, 8, 7.
If Angle2 Is-congruent-to Angle6, which must be true about Angle2?
Angle2 Is-congruent-to Angle5
Angle2 is complementary to Angle5.
mAngle2 = mAngle8
Angle2 is supplementary to Angle8.
Answer:
Angle2 is supplementary to Angle8.
If Angle 2 Is-congruent-to Angle 6, then the statement which must be true about Angle 2 is that Angle 2 is supplementary to Angle 8.
What are Congruent Angles?
This refers to the type of angle where two different angles are said to have equal measure on their corresponding sides.
With this in mind, we can see that based on the two horizontal parallel lines are intersected by a third line, there is a third line that intersects the top line and forms four angles.
Hence, if If Angle 2 Is-congruent-to Angle 6, then the statement which must be true about Angle 2 is that Angle 2 is supplementary to Angle 8 because the sum of either angles is 180 degrees.

A guppy was swimming 8 feet below the surface of the river. It swam down 6 more feet
to escape a large, hungry fish. What is the position of the guppy now relative to the
surface?
To solve the problem, Jenna subtracted 8 - 6 and came up with an answer of 2 feet. Is Jenna
correct? Why or why not?
Yes, Jenna is correct.
No. The answer should have been -2 feet, not 2 feet, because the guppy is

Which rules define the function graphed below?
y = x; y = 5
y = x + 2; y = 5
y = x; x = 5
y = x + 2; x = 5
Answer:
B) y=x+2; y=5
Step-by-step explanation:
The rules that define the graphed function are y = x + 2; y = 5
How to determine the rule of the function?The function is a piecewise function
There are two lines on the graph.
The first line has the following points
(0,2) and (3,5)
Express 2 and 5 as a sum of 2
(0,0 + 2) and (3, 3 + 2)
This means that the y value is the sum of 2 and the x value.
So, we have:
y = x + 2
The other line has a constant value of 5 for all x values
So, we have:
y = 5
Hence, the rules that define the graphed function are y = x + 2; y = 5

Answer:
A) a= 123 b= 123 c= 57
B) d= 98 e= 98 f= 98
C) g= 75 h= 75
Step-by-step explanation:
The ones that have the same angle measurement are corresponding angles, meaning that they have -well- the same measurement.
Adjacent angles are how I figured out the measurements. If you have one angle, the angle next to it will form a straight line, or 180 degrees. You just subtract that measurement to 180 and get the other angle.
Answer:
G= 75 H=75
Step-by-step explanation:
Ok, so with these the lines are marked as parallel. All lines are equal to 180 degrees, so with the given information that one of the angles are 75 degrees, you can subtract 75 from 180 to get 105. Since both g and h did not require that, it was not entirely necessary for me to say that, but I hope that it can be helpful for you. But, because the lines are parallel, it means that the other side also has a 75 degree angle as well as a 105 degree angle. Just looking at the size of the angle that's labeled can help too. the smaller angle is 75. Since the lines are parallel, you can just find the smaller angles and mark them as 75 as well. Hope that was helpful to you!

Answer:
B.) 33
Step-by-step explanation:
15/5=3
6x3=18
18+15=33
The ratio shows how many times one value is contained in another value.
If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.
The total pints of paint used in total is 33 pints.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
The ratio of minutes and minutes in 1 hour is 60 : 3600
We have,
Purple color:
Red : Blue = 6 : 5
Let,
Red colour = 6x
Blue color = 5x
Now,
Blue color = 15 pints
5x = 15 pints
x = 15/3
x = 3 pints _______(1)
Now,
Total color.
= Red + Blue
= 6x + 5x
= 11x
Now,
From (1) we get,
= 11x
= 11 x 3
= 33
Thus,
If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.
The total pints of paint used in total is 33 pints.

It is 140° because it is supplementary to 40°. Then the correct option is A.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Angle ∠A and angle 40° are supplementary angles. Then the equation is given as,
∠A + 40° = 180°
∠A = 140°
The proportion of point ∠A will be 140°. It is 140° in light of the fact that it is strengthening to 40°. Then the right choice is A.

how can you use number patterns to find the least common factor
Answer:
The correct answer is: 360.
Explanation:
First we can express 120 as follows:
2 * 2 * 2 * 3 * 5 = 120
You can get the above multiples as follows:
120/2 = 60
60/2 =30
30/2 = 15
15/3 = 5 (Since 15 cannot be divisible by 2, so we move to the next number)
5/5 = 1
Take all the terms in the denominator for 120, you would get: 2 * 2 * 2 * 3 * 5 --- (1)
Second we can express 360 as follows:
360/2 = 180
180/2 = 90
90/2 =45
45/3 = 15 (Since 45 cannot be divisible by 2, so we move to the next number)
15/3 = 5
5/5 = 1
Take all the terms in the denominator for 360, you would get: 2 * 2 * 2 * 3 * 3 * 5 --- (2)
Now in (1) and (2) consider the common terms once and multiple that with the remaining:
2*2*2*3*5 = Common between the two
3 = Remaining
Hence (2*2*2*3*5) * (3) = 360 = LCM (answer)

Answer: 1.5x
Step-by-step explanation:
Answer:
1.5x + 3 = y
Step-by-step explanation:
−6x = 12 − 4y
1. Subtract 12 from both sides: −6x − 12 = −4y

How do u write “the quotient of c and 2 “ as a variable expression?
The variable expression c/2 represents the quotient of c and 2, where c can be any numerical value or variable.
To write "the quotient of c and 2" as a variable expression, we can use the division operation to represent the quotient.
The variable expression would be:
c/2
c represents the variable, and dividing c by 2 gives us the quotient of c and 2.
Let's break it down further to understand this expression in more detail:
The term "quotient" refers to the result of dividing one quantity by another.
We are interested in the quotient of c and 2.
The variable c represents an unknown value or a variable that can take on different numerical values.
The number 2 is the divisor or the quantity by which we divide c to find the quotient.
By using the division operator (/), we can create a variable expression that represents the quotient of c and 2.
We evaluate this expression by substituting specific values for c, we will obtain the result of dividing c by 2.
If we let c = 10, then the expression c/2 would evaluate to 10/2, which equals 5.
If c = 6, the expression c/2 would evaluate to 6/2, which equals 3.

Gina rented shoes, bowled 3 games, and bought 1 order of
nachos. She used a coupon for half off the price of her bowling
games. What was Gina's total cost?
Answer:
It would be $ 8.25 without the tax.
Step-by-step explanation:
If you add $2.75(the cost for bowling shoes) then multiply the cost for one bowling game by 3, since she played 3 games, then add that to the cost of shoes, then add the cost for the food, which gives your $12.00. Then take 50% of the price of bowling games. Which is $3.75. Then replace that with the original price of the 3 bowling games! Which gets you.....$8.2 for the total cost without tax
