Which angles represent alternate interior angles? O angles A and C O angles B and D O angles C, D, and E O angles B and C
Explanation:
Erase the line from angle C to angle A. You'll be left with only one transversal. This transversal forms angles B and D, which are alternate interior angles. They are inside the parallel lines, so that's what makes them interior. They are also on alternating sides of the transversal line. Alternate interior angles are congruent when we have parallel lines like this.
Side note: Another pair of alternate interior angles would be angle A and angle E.

The table below shows the total number of hours Jessica Emily and Trina each studied after given a number of weeks
Answer:
Trina's number of hours studied is proportional to number of weeks studied
[tex] y = 2.5x [/tex]
Step-by-step explanation:
The ratio of each pair in any given table of values must be the same all through, for the relationship between two variables to be considered proportional.
In this case, we are looking at the relationship between number of weeks (x) and total number of hours studied (y).
The ratio for a pair is given as: y/x
If the ratio value for all pairs are the same in any of the given table, then it is proportional.
❌For Jessica's table of values, the first, second and third pair of values have a ratio of 2.5, however, the fourth pair has a different ratio of 4 (y/x = 40/10 = 4). So, this relationship is not proportional.
❌For Emily, the first, and second pair has a ratio of 2.5 while the third and fourth has different ratio. This also isn't a proportional relationship.
✅For Trina, the relationship between hours studied and the given number of weeks is proportional, because all pairs have the same ratio. That is: y/x = 5/2 = 10/4 = 20/8 = 25/10 = 2.5
✍️A proportional relationship can be written as [tex] y = kx [/tex].
Where,
y = total number of hours
x = number of weeks
k = constant of proportional = 2.5 (the ratio between y to x)
To generate an equation that represents the proportional relationship in the table of values for Trina, simply plug in the value of k in [tex] y = kx [/tex].
Thus, the equation would be:
✅[tex] y = 2.5x [/tex].

Step-by-step explanation:
Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following:
13 Pennies 15 Dimes
29 Nickels 26 Quarters
What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a nickel?
Answer:
The probability is 435/6,806
Step-by-step explanation:
Firstly, the total number of coins in the jar is
13 + 15 + 29 + 26 = 83
The probability of selecting a dime is 15/83
Now we want to grab a nickel
Since we already selected a dime and we did not replace it, the number of total coins in the jar will be 83-1 = 82
So the probability of selecting a nickel this time is
29/82
So the total probability of the event in the described order is;
15/83 * 29/82
= 435/6,806
It costs $480.00 to rent an apartment on the Gold Coast for a weekend. Last year it cost $400.00.
What method below shows how you would calculate the % increase?
Answer:
The third choice.
(480 - 400) / 400 * 100.
Step-by-step explanation:
(480 - 400) / 400 * 100
= 80/400 * 100
= 1/5 * 100
= 20%.
The percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
The rent of an apartment is increased from $400 to $480.
The percentage change will be calculated as:-
Subtract $400 from $480 and you will get 80. Then divide 800 by 400 (because 100% = total) and you will get which means 20 %. Her hourly wage increased by 18%.
Percentage change = ( 480 - 400 ) / 400
Percentage change = 80 / 400
Percentage change = 0.2 x 100 = 20 %
Therefore, the percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.

Erin has quarters and nickels for a total of 16 coins. The value of his coins is $2.60. Let represent the number of quarters and y represent the number of nickels
Note: Consider we need to find each type of coins he has.
Given:
Erin has quarters and nickels for a total of 16 coins.
The value of his coins is $2.60.
To find:
The number of each type of coins.
Solution:
Let x represent the number of quarters and y represent the number of nickels.
According to the question,
Total coins : [tex]x+y=16[/tex] ...(i)
Total value : [tex]0.25x+0.05y=2.60[/tex] ...(ii)
Multiply equation (i) by 0.25 and subtract the result from (ii).
[tex]0.25x+0.05y-0.25(x+y)=2.60-0.25(16)[/tex]
[tex]0.25x+0.05y-0.25x-0.25y=2.60-4[/tex]
[tex]-0.20y=-1.40[/tex]
Divide both sides by -0.20.
[tex]y=7[/tex]
Put y=7 in (i).
[tex]x+7=16[/tex]
[tex]x=16-7[/tex]
[tex]x=9[/tex]
Therefore, the number of quarters is 9 and number of nickels is 7.
20. Mr. Sprengel has a total amount of 91 pens and pencils. The ratio of pens to pencils is 6:7.
How many pencils does he have?
Answer:
Mr. Sprengel has 49 pencils.
Step-by-step explanation:
We are given that Mr. Sprengel has 91 pens and pencils.
We are also given that the ratio of pens to pencils is 6:7.
We can create an equation to solve for how many pencils Mr. Sprengel has.In this case, our unknown variable is how many pencils Mr. Sprengel has.Basically, the problem is telling us that for every 6 pens, there are 7 pencils.
Therefore, we can set up an equation and set our unknown (the amount of pencils) to be equal to x.
[tex]\displaystyle6x + 7x = 91\\\\13x = 91\\\\x = 7[/tex]
Now, we found our x. However, we need to plug this into a new equation and find how many pens and pencils Mr. Sprengel has.
Our new equations are:
[tex]\bullet \ 6(7) = y\\\\\bullet \ 7(7) = z[/tex]
In this case:
y will equal the amount of pens.z will equal the amount of pencils.Therefore, let's solve these:
[tex]6(7) = y\\\\y = 42\\\\\\7(7) = z\\\\z = 49[/tex]
Now, finally, we need to insert these values into our newfound equation:
[tex]\bullet \ y + z = 91[/tex]
[tex]42 + 49 = 91\\\\91 = 91 \ \checkmark[/tex]
We get a true statement, so we have determined that Mr. Sprengel has:
42 pens49 pencils

Wright an equation in slope-intercept (y=Mx+b) form for each line.
Answer:
[tex] y = \frac{3}{5}x + 2 [/tex]
Step-by-step explanation:
Find slope (m) using two points (0, 2) and (5, 5):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{5 - 0} = \frac{3}{5} [/tex]
y-intercept (b) = 2 (i.e the value of y when x = 0)
Substitute m = ⅗ and b = 2 in [tex] y = mx + b [/tex]
The equation of the line would be:
✅[tex] y = \frac{3}{5}x + 2 [/tex]

What is the equation of the line below?
Answer:
[tex] y = -\frac{2}{3}x + 1 [/tex]
Step-by-step explanation:
The equation of the line shown can be expressed in the slope-intercept formula as [tex] y = mx + b [/tex]
Let's find m = slope, and b = y-intercept.
Using two points on the line, (0, 1) and (1½, 0),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 1}{\frac{3}{2} - 0} = \frac{-1}{\frac{3}{2}} = - \frac{2}{3} [/tex]
y-intercept, b is where the line intercepts the y-axis = 1.
To create an equation for the line, substitute m = -⅔, b = 1 in [tex] y = mx + b [/tex].
✅The equation would be:
[tex] y = -\frac{2}{3}x + 1 [/tex]

How do you do this question?
Step-by-step explanation:
Find the next term of the Taylor series.
f⁽⁰⁾(x) = x^⅓
f⁽¹⁾(x) = ⅓ x^-⅔
f⁽²⁾(x) = -²/₉ x^-⁵/₃
f⁽³⁾(x) = ¹⁰/₂₇ x^-⁸/₃
f⁽⁴⁾(x) = -⁸⁰/₈₁ x^-¹¹/₃
So the fourth term would be:
(-⁸⁰/₈₁ z^-¹¹/₃) (x − 1)⁴ / 4!
For 0.8 ≤ z ≤ 1.2, │f⁽⁴⁾(z)│is a maximum at z = 0.8. Therefore:
│R₃(x)│≤ │(-⁸⁰/₈₁ (0.8)^-¹¹/₃) (0.8 − 1)⁴ / 4!│
│R₃(x)│≤ 0.00014923
