Answer:

ASA

Step-by-step explanation:

Angle Side Angle

As two lines are parallel, alternate interior angles are congruent and the side between these angles are common for both triangles

This is the same as saying x = 3 and x = 7.

========================================

Work Shown:

Plug x = 3 into f(x)

f(x) = (1/2)*|x-3| + 3

f(3) = (1/2)*|3-3| + 3

f(3) = 0.5*|0| + 3

f(3) = 0.5*0 + 3

f(3) = 0 + 3

f(3) = 3

-----------------------

Plug x = 5 into f(x)

f(x) = (1/2)*|x-3| + 3

f(5) = (1/2)*|5-3| + 3

f(5) = 0.5*|2| + 3

f(5) = 0.5*2 + 3

f(5) = 1 + 3

f(5) = 4

-----------------------

Plug x = 7 into f(x)

f(x) = (1/2)*|x-3| + 3

f(7) = (1/2)*|7-3| + 3

f(7) = 0.5*|4| + 3

f(7) = 0.5*4 + 3

f(7) = 2 + 3

f(7) = 5

-----------------------

Plug x = 3 into g(x)

g(x) = sqrt(x-3) + 3

g(3) = sqrt(3-3) + 3

g(3) = sqrt(0) + 3

g(3) = 0 + 3

g(3) = 3

-----------------------

Plug x = 5 into g(x)

g(x) = sqrt(x-3) + 3

g(5) = sqrt(5-3) + 3

g(5) = sqrt(2) + 3

g(5) = 1.414214 + 3

g(5) = 4.414214 ..... which is approximate

-----------------------

Plug x = 7 into g(x)

g(x) = sqrt(x-3) + 3

g(7) = sqrt(7-3) + 3

g(7) = sqrt(4) + 3

g(7) = 2 + 3

g(7) = 5

-----------------------

To summarize everything, refer to the table below.

The rows highlighted in yellow refer to when f(x) = g(x)

This happens twice when x = 3 and x = 7

If x = 3, then f(x) = g(x) = 3

If x = 7, then f(x) = g(x) = 5

Therefore, x = 3 and x = 7 are two solutions to f(x) = g(x)

Answer:

20/40

Step-by-step explanation:

If you make them decimals, then 17/40 = .43

0/40= .00    20/40 = .50    40/40 =1.00

so .50 is closest to .43.

Recall that

sin²(θ) + cos²(θ) = 1

for all θ, and given that cos(θ) < 0, we find that

cos(θ) = -√(1 - sin²(θ)) = -√(1 - (2/5)²) = -√(21)/5

Now,

csc(θ) = 1/sin(θ) = 1/(2/5) = 5/2

and

cot(θ) = cos(θ)/sin(θ) = (-√(21)/5)/(2/5) = -√(21)/2

Answer:

I think is it 3/13

Step-by-step explanation:

Hope this helped have an amazing day!

Understanding:

First of all, each time Xavier buys lunch he saves a nickel. That means if he buys lunch twice, he is saving 2 nickels, buys 3 times he saves 3 nickels, and so on. To solve this problem we can simply add the times he bought lunch and that will equal the value of nickles he saved so far.

Solution:

First-week savings = 4 nickels

Second-week savings = 2 nickels

Simply, adding those together gives us 6 nickels.

Answer:

You can use the coordinates of a figure to find its dimensions by finding the distance between two points. To find the distance between two points with the same x-coordinates, subtract their y-coordinates. To find the distance between two points with the same y-coordinates, subtract their x-coordinates.

Answer:

32 students were present.

Step-by-step explanation:

To find out how many students were present in class 8, we have to find out how many students were absent first.

As the question has already provided us, the number of students who are absent would be [tex]40 \cdot 20\%[/tex], which equals to [tex]40 \cdot \frac{20}{100}[/tex] which is 8 students in total who were absent in class 8.

Now that we have found out how many students were absent, simply subtract the number of students who were absent from the total number of students in class 8, which is (40 - 8) = 32 students, and you have the number of students that were present: 32.

Hope this helped!

Answer:

The answer is x= 50 and y=50.

Step-by-step explanation:

So a straight line is always equal to 180 degrees. So, to find the length of the inner angle, subtract 100 from 180= 80. Now that you've gotten the value of that angle, you'll have to find x and y. All angles of a  triangle add up to 180 degrees. 180-80= 100. The small dash on both of those lines means they are equal. Do 100/2 = 50. Hope this helps!

Answer:

B

seems to be the most precise. I don't know what it means by precise but B is the lucky guess

This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.

Answer:

it's B a linear pair

because when you add them they make 180 °

Answer: D: Column G​

Step-by-step explanation:

If n is the number of items sold and c is the cost per item, multiplying n and c would give the total expenses for selling that item.

As expenses are in column G, this is therefore the right column to use n * c.

This is can be proven by using the Lollipops as an example.

n = 85

c = $0.12

n * c = 85 * 0.12 = $10.20

$10.20 is the amount of expenses for lollipops in Column G so Column G must be right.

Answer:

c

Answer:

The answer is 2/3

Step-by-step explanation:

2/3 = 0.6666666666... with it repeating forever

Answer:

2/3

Step-by-step explanation:

The answer you selected is correct.

The decimal form of 2/3 is 0.66666666 (it repeats forever), unlike the other three:

3/4 = 0.75

4/5= 0.80

7/8= 0.875

Answer: 230 ducks were left.

Step-by-step explanation:

Answer:

31 ducks

Step-by-step explanation:

345 ÷ 33 1/3% = ducks left.

345 ÷ 33 1/3% = approximately 31

So once solved, you can conclude that there are 31 ducks left in the pond.

Answer:

Non-linear.

Step-by-step explanation:

The rate of change from t1 to t2 is different from the rate of change of t3 to t4 which makes this non-linear.

THE MONEY

Step-by-step explanation:

Incomplete question. The missing question read;

Which of the following best describes why a matched-pairs design is an appropriate design for the investigation?

a. Each graduate was randomly assigned to one method.

b.  The law schools were randomly selected.

c.  Each method served as a block.

d.  The sample size was less than 30.

e.  Each law school served as a block, and the graduates were paired within each law school and randomly assigned to one of the two methods.

Answer:

e.  Each law school served as a block, and the graduates were paired within each law school and randomly assigned to one of the two methods.

Step-by-step explanation:

Note, the matched pairs design is typically used when the experiment has two independent variables (treatment conditions), so the subjects of the experiment are grouped into pairs based on some common variable relationship they have before been randomly assigned to the treatment conditions.

In this case, the graduates were paired within each law school and randomly assigned to one of the two methods (the two treatment conditions).
