The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ Divide (3x² - 14x - 5) by (x - 5)

Now,

Divide (3x² - 14x - 5) by (x - 5) as;

x - 5 ) 3x² - 14x - 5 ( 3x + 1

        3x² - 15x

      -      +

      ------------------

               x - 5

              x - 5

           -      +  

         --------------------

                0

Thus, The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

Answer:

Step-by-step explanation:

Were just looking at the top triangle because it has the points A,B, and D. now we solve for x (aka answer the equation in the parentheses). We need to get rid of the 22 so we only have x. We do that by adding it to itself so it equals 0. What we do to one side we do to the other. Now adding 22 to 9 we get 31 (put the x back).

 9x - 22

+22 +22

9x - 22 = 31x

Find the x value of the system of equations. Use the technique of ELIMINATION to solve this problem. Proper work must be shown on your work submission. 3x-2y=4 5x+y=11 the answer choices are 2 , -1 , 1 , -2

Answers

Answer:

2

Step-by-step explanation:

Given the equation :

3x - 2y = 4 - - - (1)

5x + y = 11 - - - (2)

Multiply (1) by 1 and (2) by 2

3x - 2y = 4 - - - - - (3)

10x + 2y = 22 - - (4)

Add (3) and (4)

13x = 26

x = 26/13

x = 2

If 12 X 15 = 180 then what would 24 X15 equal (without solving it on paper)? Is there an easy way to figure out the answer? If so, explain.

Answers

Answer:

360

Step-by-step explanation:

It's a simple concept. All you have to do is double the answer! Here's why:

We already know that 12 x 15 is 180. Now we're trying to figure out 24 x 15. 24 is 12 two times, or 12 doubled. Since 12 is doubled, the answer should also be doubled.

Let's take an easier example: 3 x 2.

The answer is 6. What if you doubled the 3 to get 6 x 2? The answer is 12, which is 6 doubled. By doubling the multiplier or multiplicand of the problem, you are also doubling the answer.

It's not just doubling, either. If 3 x 2 is 6. Then 9 x 2 is 18. You tripled the multiplier which is 3, so the answer is also tripled.

Hope this makes some sense lol

When will Peter's baseball hit the ground? Use mathematical evidence to explain your answer.

Answers

Question:

The height of Peter’s baseball is given by the graph below (See attachment)

When will Peter’s baseball reach the highest height? What is the height?  When will Peter’s baseball hit the ground? Use mathematical evidence to explain your answer.

Answer:

Peter's baseball reached the maximum height at 1.5 secondsPeter's baseball hit the ground at 4 seconds

Step-by-step explanation:

The (a) & (b) will be answered by making reference to the attachment.

Solving (a): Time to reach maximum height

The height is plotted at the vertical axis while the time taken is at the horizontal axis.

From the attachment; the following details can be observed

The maximum height is at 90ftWhen the maximum height is traced to the horizontal axis, the corresponding time is 1.5s

Using function notations, this can be represented as:

[tex]f(1.5) = 90[/tex]

And the interpretation is that:

Peter's baseball reached the maximum height at 1.5 seconds

Solving (b): Time to hit the ground

The interpretation of this question is to solve for the x intercept of the graph.

From the attachment; the following details can be observed

The ground is at 0 feetThe corresponding time at 0 feet is 4s

Using function notations, this can be represented as:

[tex]f(4) = 0[/tex]

And the interpretation is that:

Peter's baseball hit the ground at 4 seconds

During one waiter’s shift, he delivered appetizers, entrées, and desserts. What percentage of the dishes were desserts? appetizers? entrées? What do your percentages add up to?
15 desserts
10 entrees
15 appetizers

Answers

Answer:

percentage of the dishes were desserts = 37.5%

percentage of the dishes were entrees = 25%

percentage of the dishes were appetizers = 37.5%

Total percentage = 100%

Step-by-step explanation:

Desserts = 15

Entrees = 10

Appetizers = 15

Total dishes = desert + entrees + appetizers

= 15 + 10 + 15

= 40

What percentage of the dishes were desserts?

= 15 / 40 × 100

= 0.375 × 100

= 37.5%

What percentage of the dishes were entrees?

= 10 / 40 × 100

= 0.25 × 100

= 25%

What percentage of the dishes were appetizers?

= 15 / 40 × 100

= 0.375 × 100

= 37.5%

What do your percentages add up to?

Total percentage = 37.5% + 25% + 37.5%

= 100%

Ricardo has $25 to spend on school supplies. He spends 56% of the money on a backpack and the rest on a large binder. How much money does he spend on the backpack? How much does he spend on the binder

Answers

Answer:

Ricardo spends $14 on the backpack and $11 o the binder.

Step-by-step explanation:

First, you have to calculate 56% of the amount Ricardo has to spend on school supplies to find the money he spends on the backpack:

$25*56%=$14

Now, you have to subtract 56% from 100% to find the percentage that he spent on a large binder:

100%-56%=44%

Finally, you have to calculate the 44% of the amount Ricardo has to spend on school supplies to find the money he spends on a large binder:

$25*44%=11

According to this, the answer is that Ricardo spends $14 on the backpack and $11 o the binder.

The monthly salry of Mr jha is Rs 165000.he spends his income in every month in the following ways food 20 percent house rent 25 percent fuel 10 percent miscellaneous 15 percent find his monthly expenditure on each item. how much does he save every month ​

Answers

Answer:

Total monthly expenditure = Rs 115,500

Total savings = Rs 49,500

Step-by-step explanation:

Total salary = Rs 165000.

Food = 20%

= 20/100 × Rs 165,000

= 0.2 × 165,000

= Rs 33,000

House rent = 25%

= 25/100 × Rs 165,000

= 0.25 × 165,000

= Rs 41,250

Fuel = 10%

= 10/100 × Rs 165,000

= 0.1 × 165,000

= Rs 16,500

Miscellaneous = 15%

= 15/100 × Rs 165,000

= 0.15 × 165,000

= Rs 24,750

Total monthly expenditure = food + house rent + fuel + miscellaneous

= Rs 33,000 + Rs 41,250 + Rs 16,500 + Rs 24,750

= Rs 115,500

Total monthly expenditure = Rs 115,500

Total savings = Total salary - Total expenditure

= Rs 165,000 - Rs 115,500

= Rs 49,500

Total savings = Rs 49,500

A gymnast's score for a routine is calculated by finding the sum of a difficulty score and an execution score, minus any penalties. The execution score starts at 10 and is reduced by deductions. The gymnast's score can be represented by: 6.9 + (10 – 1.534) – 0.3. What is the gymnast's score?

Answers

Answer:

the gymnast score is 15.066

Step-by-step explanation:

The computation of the gymnast score is shown below:

Given that

6.9 + (10 - 1.534) - 0.3

Here the 10 denotes the execution score

6.9 denotes the difficulty score

0.3 denotes the penalties

Based on the above information, the gymnast score is

= 6.9 + (10 - 1.534) - 0.3

= 6.9 + 8.466 - 0.3

= 15.066

Hence, the gymnast score is 15.066
