When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.

Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.

See the drawing attached below.

Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:

m<DIE + m<HID = 18

40 + m<HID = 180

m<HID = 140

Similarly:

m<BHC + m<CHI = 180

130 + m<CHI = 180

m<CHI = 50

Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:

m<DIE = m<GIH = 40

m<GIE = m<HID = 140

m<CHI = m<AHB = 50

m<BHC = m<AHI = 130

A study compared the number of years of education a person received and that person's yearly salary. It was determined that the relationship between these two quantities was linear and the correlation coefficient was 0.91. Which conclusion can be made based on the findings of this study?

Answers

Answer:

Salary earned increases as the number of years of education earned increases.

Step-by-step explanation:

Given that the correlation between the number of years of education a person receive and his yearly salary yields a linear relationship with a correlation Coefficient of 0.91, this shows that a strong positive relationship exists between the two measured quantities, this is deduced by the positive nature of the correlation Coefficient value obtained and the fact that the value of the Coefficient is close to 1. Hence, salary earned increases as the number of years of education increases and Vice versa.

Check for valid triangles

Given 3 sides of a triangle: A triangle is valid If the sum of any two sides is greater than the third

1. Sides: 2cm, 3cm and 4cm

To check:

2cm + 3cm > 4cm --- True

2cm + 4cm > 3cm ---- True

3cm + 4cm > 2cm ----- True

The above conditions are true, hence the input values form a triangle.

2. Sides: 2cm, 3cm and 6cm

To check:

2cm + 3cm > 6cm --- False

2cm + 6cm > 3cm ---- True

3cm + 6cm > 2cm ----- True

One of the above conditions is false. Hence, the input values do not form a triangle.

Given the angles of a triangle, their sum must be equal to 180°

3. Angles: 90°, 45° and 45°

Sum = 90° + 45° + 45°

Sum = 180°

This is a valid triangle because the sum equals 180°

4. Angles: 90°, 60° and 60°

Sum = 90° + 60° + 60°

Sum = 210°

This is not a valid triangle because the sum does not equal to 180°

The above conditions are true, hence the input values form a triangle.

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?

Answers

Answer:

FV= $8,436

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,700

Simple interest (i)= 8% = 0.08

Number of periods (n)= 6 years

To calculate the future value (FV), we need to use the following formula:

FV= PV*i*n + PV

FV= 5,700*0.08*6 + 5,700

FV= $8,436

longest side must be less than the sum of the legnths of the other 2 sides


if we assume that 7 is longest then missing side is x so
3+x>7
minus 3
x>4
whole number to satisfy is
x=5

if we assume the missing side is the largest
3+7>x
10>x
x is 9 at most


if the third side is not the longest side, it can be 5 at minimum
if the third side is the longest side, it can be 9 at max

so the third side can be 5,6,7,8,9 ft

Solve for x: 7x + 15 = 38

A: 23/7
B: 53/7
C: 23
D: 53

Answers

Answer: A

Step by Step: to isolate 7x, subtract 15 from both sides of the equation. 15-15=0. 38-15=23.

now the equation is 7x=23

finally, to completely isolate the variable, divide 7 from both sides. 7x/7= x. 23/7=23/7 because it cannot be simplified further unless you want it to be a decimal.

so the answer is A, 23/7

Elena bought 8 tokens for $4.40. At this rate: 1)How many tokens could she buy with $6.05? 2) How much do 19 tokens cost?

Answers

11 tokens.
Step-by-step explanation:
First you need to find how much each token costs.
to do this, we need to divide the cost by the number of tokens.
4.40 ÷ 8 = 0.55. So, each token costs 55 cents/ $0.55.
Next, you need to find how many tokens she can afford.
to do this, we need to divide how much money she has by the cost of each token.
6.05 ÷ 0.55 = 11. So, she can buy 11 tokens in total.

Answer: She could buy 11 tokens and 19 tokens cost 10.45

Step-by-step explanation:

divide how much money you spent by how many tokens you bought

4.40/8=0.55 x 19= 10.45

6.05/0.55=11

Rebecca is distributing fidget spinners as part of her campaign for school president. she has 500 fridge my spinners to distribute in packs of 25 per teacher. write a function modeling this situation. define all unknown variables

Answers

Answer:

Y= 20

Step-by-step explanation:

From the question, Rebecca has 500 fridge my spinners to distribute in packs of 25 per teacher, we can denote the number of this teacher with "Y" then for her to distribute those 500 fridge in packs of 25 per teacher, then we can say (25× Y)= 25Y ,since she has 500 fridge in total to distribute then we can write a write a function modeling this situation as

25Y=500

where Y is the number of teacher

Make Y subject of the formula we have

Y= 500/25

Y=20

Answer:

25x=500 or x=20

Step-by-step explanation:

__

Well Rebecca have 500 fidget spinners so you put that  on one end and let x be the number of teachers if you have 25 fidget spinners per teacher you need to multiply 25 by the number of teachers or x to find out so the equation will look like this: 25x=500

If you want to simplify you divide by 25 into both sides which are 20

Find X if m/angle UVY=84 degrees.

Answers

Answer:

x = 42º

Step-by-step explanation:

We know that m < UVY is equal to 84º (Given)

We know that < UVY = < SVW (Vertical Angles Theorem)

By substituting in the known values for the anges, we know that:

< UVY = < SVW

84º = 2x

Simplify the equation by dividing by 2 on both sides.

x = 42º

Hope this helps! Let me know if you have any questions!

Find coordinates of the image of the point A(3,9) for a dilation with the scale factor of 2/3

Answers

Answer:

The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

Step-by-step explanation:

Given the point A with the vertices (3, 9) i.e. A(3,9)

As we know that If the scale factor is between 0 and 1, the image gets shrunk.

In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.

i.e.

(x, y) → (2/3 x, 2/3 y)

so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:

A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)

Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)
