Answer:
first, how much were her songs? It's two songs each, and their separate prize was 0.99:
total prize was 2*0.99=1.98
this gets added to the membership prize:
19.99+1.98=21.97
you can also calculate this by rounding all the numbers (20+1+1) and substracting the amount you rounded (three times one cent) - the result would be the same.
B 19.99+.99n
C okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total

The ordered numbers from least to greatest are 33/100 = 0.33, 4/10 = 0.4, 5/10 = 0.5, 6/100 = 0.06, 3/4 = 0.75.
How do you convert fractions to decimals?Divide the top number or numerator into the bottom number or denominator.
6/100 = 0.065/10 = 0.54/10 = 0.43/4 = 0.7533/100= 0.33How to organize the numbers?When organizing decimal numbers you need to follow the same rules than when organizing regular numbers. For example, 0.5 is greater than 0.4 because 5 is greatest than 4.
Based on this, the correct order is:

On a coordinate plane, 3 lines are shown. Line a has points (negative 3, 3) and (3, negative 3). Line b has points (negative 3, negative 2) and (2, 3). Line c is parallel to line b.
If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?
Answer:
slope c =1
Step-by-step explanation:
slope for line (y2-y1)/(x2-x1)
slope of line a = (-3-3)/(3-(-3))
slope of line a = -6/6 = -1
if line c is perpendicular to line a, so relationship for slops are
(slope a) *(slope c)= -1
(-1)*(slope c) = -1
slope c =1

how to solve (3p⁴ + 2q⁴)²
Answer:
9p⁸ + 12p⁴q⁴ + 4q⁸
Step-by-step explanation:
(3p⁴ + 2q⁴)² ⇒ The square of (3p⁴ + 2q⁴)
Squares are such bases that multiply itself two times.
⇒ (3p⁴ + 2q⁴)(3p⁴ + 2q⁴)
Simplifying the expression using (a + b)(a + b) = (a x a) + (ab) + (ab) + (b²)
⇒ (9p⁸ + 6p⁴q⁴ + 6p⁴q⁴ + 4q⁸)
⇒ (9p⁸ + 12p⁴q⁴ + 4q⁸) = 9p⁸ + 12p⁴q⁴ + 4q⁸
We know the identity
(a+b)²=a²+b²+2abSo
[tex]\\ \rm\Rrightarrow (3p^4+2q^4)^2[/tex]
[tex]\\ \rm\Rrightarrow (3p^4)^2+(2q^4)^2+2(3p^4)(2q^4)[/tex]

slope: 7; y-intercept: 2
slope: 2; y-intercept: 7
slope: -2; y-intercept: 7
slope: 1/2; y-intercept: 7
Answer:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Reorder 7 7 and −2x - 2 x . Using the slope-intercept form, the slope is −2 .

Using the Empirical Rule, it is found that 68% of the data should be between 25.5 and 30.5.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:
28 - 2.5 = 25.5.28 + 2.5 = 30.5.Within one standard deviation of the mean, hence, 68% of the data should be between 25.5 and 30.5.

Answer: 126 mm^2.
Step-by-step explanation: When finding the area of a trapezoid, you need to add two bases, multiply the height, and divide it all in half. The steps are done below:
First, we need to find the bases and the height. The bases are are circled below, but it's basically the top and bottom lengths of the triangle. Base 1 doesn't have to be 10 either, it can be 18 base 2 can be 10, whichever works for you. All you need is to assign each base with a top or bottom length. The height is how tall the trapezoid is, which is also circled below.Secondly, we need to add the bases and multiply the height. B1 is base 1, b2 is base 2, and h is the height. It should look like this: 10 (b1) + 18(b2) = 28, then 28 x 9(h) = 252.Lastly, we need to divide 252 in half, which you can do in two ways. You can either simply divide 252 by 2, or multiply 252 by 1/2, which both give you the answer 126 mm^2, which is your answer.Have a great day! :)

The area of the figure is
square units?
Answer:
8 squared units
Sorry if this answer is not correct, if it is or is not, please tell me in the comments!
Step-by-step explanation:
Rectangle:
To find the area of the rectangle, we need to mutiply the base and the height. 3 units(base) x 2 units(height) = 6 squared units
Triangle:
To find the area of the triangle is very similar to finding the area of the rectangle. We need to multiply the base and the height and divide it by 2.
Base= 2 units(since it is a rectangle, the opposite side is the same length)
Height = 2 units
Next, we plug it in to this formula: 1/2 bh (b = base and h = height)
multiplying by one half is the same as dividing by 2
The area of the triangle is 2 x 2 = 4
4 divided by 2 = 2 squared units
For the final step, we add the areas together. (6+2 = 8) the label is very important (squared units)

The volume of this right trapezoidal prism is 341.25 ft³.
What is the height, x, of the prism?
Enter your answer as a decimal in the box.
Answer:10.5
Step-by-step explanation: I hope this helps
The height, x, of the right trapezoidal prism is 10.5 ft.
Given that, the volume of this right trapezoidal prism is 341.25 ft³.
We need to find the height x, of the prism.
What is the formula to find the volume of this right trapezoidal prism?The formula to find the volume of this right trapezoidal prism is Volume=BH.
Where B=Area of the Base and H=Height.
Area of the Base(Trapezium)=1/2(a+b)×h
Where a and b are parallel sides of the trapezium and h= height of the trapezium.
Now, the area of the Base=1/2(8+5)×5=32.5 ft²
The volume of the right trapezoidal prism=32.5×x
⇒341.25=32.5×H
⇒x=10.5 ft
Therefore, the height, x, of the right trapezoidal prism is 10.5 ft.

The image shows lines AB and CD.
Are the 2 lines parallel? Explain or show your reasoning.
No
Step-by-step explanation:To classify the lines as "parallel", the distance between both x-intercepts must be equivalent to the distance between both y-intercepts. In this case, the lines are not parallel because the distance between both y-intercepts is different than the distance of both x-intercepts.
Distance between two y-intercepts: 4 unitsDistance between two x-intercepts: 5 unitsSince 4 ≠ 5, the lines are not parallel.
Answer:
No, the lines are not parallel.
Step-by-step explanation:
Parallel lines have the same slope.
Therefore, find the slopes of both lines and compare.
Slope formula
[tex]\sf slope=\dfrac{change\:in\:y}{change\:in\:x}[/tex]
Line AB
A = (0, 6)
B = (8, 0)
[tex]\implies \sf slope=\dfrac{0-6}{8-0}=-\dfrac34[/tex]
Line CD
C = (-3, 4)
D = (0, 2)
[tex]\implies \sf slope=\dfrac{2-4}{0-(-3)}=-\dfrac23[/tex]
As the slopes of the 2 lines are different, the lines are not parallel.
