C. The slope of AC is equal to the slope of line t.
D. The slope of line t is equal to EC/AE
E. the slope of line t is equal to FB/FD
F. The slope of line t is equal to AE/FD
Answers
Answer:
Options (A), (B), (C) and (E).
Step-by-step explanation:
Option (A).
Slope of AC is equal to the slope of BC.
Since, points A, B and C are collinear points,
Slopes of AC and BC will be equal.
True.
Option (B).
Since, points A, B, C and D are collinear points, slope of AC and BD will be equal.
True.
Option (C).
Points A and C are lying on line 't'.
Therefore, slope of line 't' and line AC will be equal.
True.
Option (D).
Slope of 't' = slope of line AC
= [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{AE}{EC}[/tex]
False.
Option (E).
Slope of line 't' = slope of line BD
= [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{FB}{FD}[/tex]
True.
Option (F).
Slope of line 't' = [tex]\frac{AE}{FD}[/tex]
False.

The ratio of the areas of similar polygons is 64: 16. What is the ratio of their sides
Answers
Answer:
8:4
Step-by-step explanation:
Given that,
The ratio of the areas of similar polygons is 64: 16, A₁:A₂=64: 16
We need to find the ratio of their sides. For similar polygons, the ratio of the area is proportional to the square of the ratio of their corresponding sides.
Let sides are x₁ and x₂. So,
[tex]\dfrac{A_1}{A_2}=(\dfrac{x_1}{x_2})^2\\\\\dfrac{x_1}{x_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{64}{16}}\\\\=\dfrac{8}{4}[/tex]
So, the required ratio is 8:4.

In ARST, mZR = (11x + 3)º, mZS = (x + 15), and mZT = (2x + 8).
Find mZR
Answers
Answer:
124°
Step-by-step explanation:
(11x + 3)° + (x + 15)° + (2x + 8)° = 180°
14x + 26 = 180
14x = 154
x = 11
m∠R = [11(11) + 3]° = 124°
A recent survey by the alumni of a major university indicated that the average salary of 10,000 of its 300,000 graduates was $125,000. What is the Population?
Answers
Answer:
The population is the total number of the universities graduates i.e [tex]N = 300,000[/tex]
Step-by-step explanation:
From the question we are told that
The number of students that are consider is n = 10,000
The total number of graduates is [tex]N = 300,000[/tex]
The mean is [tex]\= x = \$125 , 000[/tex]
Here the population is The total number of graduates with value [tex]N = 300,000[/tex], this is because a population is the pool from with a sample is drawn and in this case the pool is [tex]N = 300,000[/tex] while the sample with is drawn is n = 10,000

Answers
Answer:
25
Step-by-step explanation:
take C as what Cj has, and J what Jordan has.
Cj has $50 more than Jordan has, so:
C = 50 + J
Together they have $100, so:
C + J = 100
is a system of 2 equations with 2 unknown (C and J):
C - J = 50
C + J = 100
Adding both equations:
2C = 150 ⇒ C = 75
From second equation: J = 25

The slope of the line is 2/5, and it contains the point: (−2, 7).
Answers
Answer:
y = 2/5x + 39/5
Step-by-step explanation:
point slope form is y = mx + b
so far we have y = 2/5x + b
m is slope which is given. We need to find b which is y-intercept.
They give us the point (-2,7). We can plug this into the equation to find b.
7 = 2/5(-2) + b
7 = -4/5 + b
b = 39/5
The equation now looks like y = 2/5x + 39/5

The question is, "Find the volume of the bodies given in the figures below, which have a hole along their entire length." How do I measure it the volume in this case?
As you can see, height is 9cm, length is 12, and width is 18 .
Answers
Answer:
1782 cm³
Step-by-step explanation:
First, you measure the volume of the cuboid as a whole which is length x breadth x height, 9 x 12 x 18 = 1944 cm³. Then measure the volume occupied by the space, 3 x 3 x 18 since the hole runs along the entire length = 162 cm³.
Then you subtract the volume occupied by the hole from the volume of the cuboid in total, 1944 - 162 = 1782 cm³
Write the first step you would take to solve each equation.

With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance.
Answers
Here is the complete question.
With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance. Determine the finance charge, new balance, and minimum payment required for each of the next three months, and the starting balance for month 4 in the table below.
a) What is the total of minimum payments?
b) What is the total sum of the finance charges?
c) How much does the starting balance decrease after these three payments?
d)The total of your finance charges is what percent of our total payments?
Answer:
Step-by-step explanation:
Month Beginning Finance New Minimum
Balance Charge Balance Payment
1 $ 1200 24.99 1224.99 36.75
2 1188.24 24.75 1212.99 36.39
3 1176.60 24.50 1201.10 36.03
4 1165.07 24.26 1189.33 35.68
a.
The total minimum payments for 3 months = 36.75 + 36.39 + 36.03
The total minimum payments for 3 months = $ 109.17
b.
Total finance charges for 3 months = 24.99 + 24.75 + 24.50
Total finance charges for 3 months = $ 74.24
c. The starting balance decrease from 1200 to 1165.07, this implies that there is a reduction of $ 34.93
d. The total of finance charges = 74.24×(100/109.17)
The total of finance charges = 68% of total payments.

Sasha sells T-shirts. Each day she earns a set amount, plus a commission.
Assume Sasha sells 24 T-Shirts in one day. How much would she earn that day?
Answers
Answer:
137$
Step-by-step explanation:
Let the slope of the equation be
[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]
where y = Total pay
x = T-shirts sold
Take any two values of x and corresponding y value
[tex]m=\dfrac{71-68}{2-1}\\\Rightarrow m=3[/tex]
The equation will be
[tex]y=mx+b[/tex]
Finding b
[tex]68=3\times 1+b\\\Rightarrow b=68-3\\\Rightarrow b=65[/tex]
The equation is
[tex]y=3x+65[/tex]
Now sasha sells 24 shirts [tex]x=24[/tex]
[tex]y=3\times 24+65\\\Rightarrow y=137[/tex]
Sasha would earn 137$ on that day.
