Can anyone help me I don't get it

Answers

Answer: (A) Kurt's expression; x = 4.6k

(B) Jared's expression; y = 4.4j

(C) Team's score; z = 4.6k + 4.4j

(D) Team score = 40.6 m

Step-by-step explanation: In order to calculate the average of a given set of data, the formula is to sum up the given data or values and then divide the sum total by the number of values observed. That means, if for instance a student jumps 10 times, his average would be given as the sum of all 10 distances jumped divided by 10. If the sum derived equals 50, then the student's average is 50 divided by 10. In other words;

Average = (∑x)/x

When we cross multiply, this can also result in

Average*x = ∑x

The question has given us the average for both students, hence we can derive their average as described above. If Kurt jumps k number of times, then his average jump will be;

4.6 = (∑k)/k

And remembering that Average*x is the same value as ∑x, we substitute for the value given in the question, which is k. Hence,

4.6*k = ∑k

Note that the total score for each boy can now be determined as the average calculated times the total number of jumps, that is, working backwards. Hence, Kurt's total score is 4.6k.

(a) If we represent Kurt's score as x, then we can express his score as

x = 4.6k ------(1)

(b) If we represent Jared's score as y, then we can express his score as

y = 4.4j ------(2)

(c) The team score is the sum of the scores of both boys. Hence, if the boys scores have been written in terms of x and y then the team score shall be represented by z. Therefore we now have;

z = x + y

z = 4.6k + 4.4j

(d) If Kurt jumps 5 times then his total score will be

x = 4.6k

x = 4.6(5)

x = 23 m

If Jared jumps 4 times then his total score will be

y = 4.4j

y = 4.4(4)

y = 17.6 m

The team score therefore is determined as

z = x + y

z = 23 + 17.6

z = 40.6

The team score is a total of 40.6 m

solve the following system x=2 5x+4y=-22

Answers

Answer:

x = 2

y = -8

Step-by-step explanation:

Since it already gives you x, all you need to do is plug it into the equation:

5x + 4y = -22

5(2) + 4y = -22

10 + 4y = -22

Then, subtract 10 from both sides:

10 + 4y = -22

- 10         - 10

__________

4y = -32

Finally, divide both sides by 4:

4y = -32

y = -8

So now you have, x = 2 and y = -8

Answer:

X=2

5x +4y= -22

5(2)+4y = -22

10+4y= -22

4y= -22-10

4y= -32

Y= -8

The answers are :

X = 2

Y = -8

What is a triangle?

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.

Since the triangle is a scalene triangle, all the sides of the given polynomial can not be equal. Therefore, it can not be a rhombus or a square.

Also, it is given that the triangle is an obtuse triangle therefore, there will be no angle with a 90° measurement. Thus, it can not be a rectangle.

Hence, the correct option is A.

A new printer can print a batch of newsletters twice as fast as an older printer. With both printers working together, the newsletters can be printed in 45 minutes. How long would it take the newer printer working alone?

Answers

Answer:

It would take 1 hr, 7 min, 30 sec for the newer printer to work alone.

Step-by-step explanation:

x/1.5=45

45*1.5=67.5 minutes

67.5 minutes = 1 hr, 7 min, 30 sec

Final answer:

The time it would take for the new printer working alone to print a batch of newsletters is 67.5 minutes. This is determined by setting up an equation based on the combined work rates of the new and old printers.

Explanation:

The student is asking how long it would take for a new printer, which can print twice as fast as an older printer, to complete printing a batch of newsletters on its own if both printers can finish the task together in 45 minutes. This question involves setting up and solving a problem related to rates of work.

Let's denote the time it takes for the new printer to print the newsletters alone as T minutes. Since the new printer works twice as fast as the old printer, the old printer would take 2T minutes to do the job alone. When working together, they can finish the task in 45 minutes.

We can set up the equation based on their combined work rates like this:
1/T (new printer's rate) + 1/(2T) (old printer's rate) = 1/45 (combined rate).

Let's solve for T:

Calculate the combined rate of the printers: 1/T + 1/(2T) = 1/45

Combine the fractions on the left side: (2 + 1) / 2T = 1/45

Simplify the fraction to get a common denominator: 3 / 2T = 1/45

Cross-multiply to solve for T: 3 * 45 = 2T

Calculate T: 135 = 2T

Divide both sides by 2: T = 135 / 2

Finish solving: T = 67.5

Therefore, the new printer working alone would take 67.5 minutes to print the batch of newsletters.

Larry accumulated $3,000 in credit card debt. If the interest rate is 10% per year and he does not make any payments for 2 years, how much will he owe on this debt in 2 years for monthly compounding?

Answers

Answer:

3,655.21

Step-by-step explanation:

The amount that Larry owes on his debt after 2 years is $20,514.

What is compound interest?

The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.

Given information is for monthly compounding as below,

The accumulated money in credit card is, P = $3000.

The rate of interest is 10% per year.

Then, the rate of interest per month is, r = 10/12 = 5/6%.

The time for compounding in years is 2 years.

Then in months, n = 2 × 12 = 24 months.

The formula for amount in compound interest is given as,

A = P(1 + r/100)ⁿ

Substitute the corresponding values to get,

A = 3000(1 + (5/6)/100)²⁴

   = 3000 × 6.838

   = 20514

Hence, the amount owed by Larry on the debt after 2 years is $20,514.

Consider the diagram below where measure of angle CDE=127 degrees.
Select all of the statements that are true.
A. measure of angle EDF=53 degrees

B. measure of arch EGD=127 degrees

C. measure of arch ED=106 degrees

D. measure of angle GAE=53 degrees

E. measure of arch EGD=254 degrees

Answers

The statements A and D are true.

Based on the diagram, here are the true statements:

A. measure of angle EDF=53 degrees:

This is true because angle EDF and angle CDE are supplementary angles, meaning they add up to 180 degrees.

Since we're given that measure of angle CDE=127 degrees, we can find measure of angle EDF by subtracting 127 from 180:

measure of angle EDF = 180 degrees - 127 degrees = 53 degrees.

D. measure of angle GAE=53 degrees:

This is true because angle EDF and angle GAE are corresponding angles.

Corresponding angles are pairs of angles that are on opposite sides of a transversal and that share a common endpoint with the transversal.

They are equal in measure.

Since we've already determined that measure of angle EDF=53 degrees, we can conclude that measure of angle GAE=53 degrees as well.

Therefore, the statements A and D are true.

Answers

Answer: Albert's gross pay for this pay period is $384.75

Step-by-step explanation:

Given : Albert's hourly pay is $8.10

His hourly pay is $12.15 when he work more than 40 hours

Last week working hours = 45 hours

Therefore

For first 40 hours he got $8.10 hourly and for more 5 hours he got  $12.15 hourly

So

Pay of first 40 hours = [tex]40 \times 8.10[/tex] = $324

Pay for next 5 hours= [tex]5 \times 12.15[/tex] = $ 60.75

Total Gross pay =  $324+$ 60.75 =$384.75

Hence , Albert's gross pay for this pay period is $384.75

Answers

Answer & Step-by-step explanation:

In order to solve for x, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

Instead of using the original formula, we will rearrange the formula so we can find the missing side, b, which will represent x.

[tex]b^2=c^2-a^2[/tex]

Now, lets plug in our numbers.

[tex]b^2=120^2-76^2\\b^2=14400-5776\\b^2=8624\\\sqrt{b^2} =\sqrt{8624}\\ b=92.87[/tex]

So, x equals 92.87

Now, lets find y. Since we did the Pythagorean Theorem, this shows that the triangle is a right triangle. So, that means we already know the measurements of two angles which will help us find y.

180 - (35 + 90)

180 - 125

55

So, y equals 55

What is Pythagoras theorem?

Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².

The diagram for the given problem can be shown below,

Here, AB = AC = 10 feet and AD = 7 feet.

Apply pythagoras theorem in ΔABD to get,

AD² + BD² = AB²

Substitute the corresponding values to obtain,

BD² = 10² - 7²

⇒ BD = 7.14

Now, CB = 2 × BD

⇒ CB = 2 × 7.14 = 14.28

Hence, the length of the base is given as 14.28 feet.
