Answers

Answer 1

Answer:

1: 4.5 cups of flour

2: 12.125 ft of rope

3: 68.5 inches above ground

4: 21.3333..... ounces of water

5: 2.5 ft below the surface

Step-by-step explanation:

1: 8.25-3.75=4.5

2: 15.5-3.375=12.125

3: 92.75-24.25=68.5

Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?

A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.

Answers

Answer: B the side length of XZ is 28

Step-by-step explanation:

to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.

for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.

Answer:

B

Step-by-step explanation:

Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.

It is proportional by 2/3 because if you put y/x and simplify the fraction you get that each fraction is simplified to 2/3 which means they are proportional. I hope this helps. If not make a comment and ask.

a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?​

Answers

To estimate the number of students per grade level in the state, we can use the sample average and the margin of error to construct a confidence interval.

The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.

So, the confidence interval is:

178.6 ± 45.2

To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:

(178.6 + (178.6 - 45.2)) / 2 = 311.6

Therefore, the estimated number of students per grade level in the state is 311.6

The answer would be 3 miles on each of the six days

Answer:

In a week we have 7 days.

On the first day, Clare runs 4 miles.

On the other six days, she runs the same distance, let's call it D.

In total, she runs 22 miles.

Then:

4mi + 6*D = 22 mi

6*D = 22mi - 4mi = 18mi

D = 18mi/6 = 3mi.

Then the other 6 days, Clare runs 3 miles

Drag each expression to show whether it is equivalent to 36x+9
or 9(4x−1)
.

Answers


In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E.
Next we will look at the expression 9(4x-1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9.
9 × 4x - 9
Now calculate the product
36x - 9
This means that the equivalent for this expression is
36x - 9,, or option A.
Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together.
(36x) + (4 × 2)
Now multiply the numbers in the second parenthesis together.
(36x) + 8
Remove the parenthesis
36x + 8
Now factor out 4 from the expression to get your final answer.
4(9x + 2)
This means that the last expression is equivalent to 4(9x + 2),, or option C.
Let me know if you have any further questions
C because the last expression is equivalent to 9(4x-1).

The expression 9.00x+4.50y represents the total amount of money Harriet earns at her two jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. Which shows an equivalent expression to the given expression and correctly describes the situation?

4.50(2x+y), which shows that Harriet earns twice as much per hour at job X than job Y.

4.50(2x+y), which shows that Harriet earns 4.50 times as much per hour at job X than job Y.

13.50xy, which shows that Harriet earns $13.50 each hour she works.

13.50xy, which shows that Harriet earns $13.50 every two hours she works.

Answers

The equivalent expression that correctly describes the situation is:

13.50xy, which shows that Harriet earns $13.50 for each hour she works.

This expression represents the total amount of money Harriet earns at both jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. The coefficient of xy, which is 13.50, represents the amount of money Harriet earns per hour, regardless of which job she is working. Therefore, this expression accurately reflects the situation described

Haven't done this kinda problem in a while but I got 4/3 cm/s

Step-by-step explanation:

Using the coordinates given i put them into the formula:

        y1  -  y2

m=_________

        x1  -  x2

That gave me -16/-12, I simplified & got 4/3.

unit rate in this case would be the slope
To find the slope you need at least two points on a line
The formula would be m=y2-y1/x2-x1

16-0/12-0
16/12
Simplified we would divide by 4 since it goes into both numbers
4/3 as the answer

Use equivalent fractions to order these fractions from least to greatest: 2 over 3 , 1 over 2, 4 over 12, 5 over 6 . Explain the steps you took to find your answer.

Answers

Answer:

so u take 4/12 and do it to 1/3 then try to do lest to greatest

Step-by-step expla

2/3 5/6 1/2 1/3 try

So the fractions will be 2/3, 1/2, 4/12, and 5/6. 4/12 would be the least because when simplified, it is 1/3. Then would be 1/2 followed by 2/3 because 2/3 is more than a half. And the greatest would be 5/6 because if all the fractions had a common denominator of 3 the 5/6 would have the greatest numerator (2.5)

Tension, by its nature, seeks resolution, and the most natural resolution of this tension is for our reality to move closer to what we want. It's as if we have set up a rubber band between the two poles of our vision and current reality. People who are convinced that a vision or result is important, who can see clearly that they must change their life in order to reach that result, and who commit themselves to that result nonetheless, do indeed feel compelled. They have assimilated the vision not just consciously but unconsciously, at a level where it changes more of their behavior. They have a sense of deliberate patience--with themselves and the world-- and more attentiveness to what is going on around them. All of this produces a sustained sense of energy and enthusiasm . . . produces some tangible results, which can then make the energy and enthusiasm stronger." Who made that statement ?
