please help i really need help A.S.A.P :)
Answer:
So you know that the height that is visible above x=0 is 74.98 m From x=0 below it has a total height of 518.16m to the sea floorThat tells us that we have two parts account for
74.98+518.16m = 593.14 mStep-by-step explanation:

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
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

When will Peter's baseball hit the ground? Use mathematical evidence to explain your answer.
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 secondsStep-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 1.5sUsing 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 4sUsing 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

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.
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

Answer:
y = [tex]-\frac{1}{2}x+3[/tex]
Step-by-step explanation:
Slope of line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is give by,
Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through the points (0, 3) and (2, 2),
m = [tex]\frac{3-2}{0-2}[/tex] = [tex]-\frac{1}{2}[/tex]
Y-intercept 'b' of the given line in the graph is (3).
Since, equation of line with slope 'm' and y-intercept 'b' is,
y = mx + b
Therefore,equation of the line given in graph will be,
y = [tex]-\frac{1}{2}x+3[/tex]

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

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

Answer:
45.5 points per gamesl
Step-by-step explanation:
Cole averaged 35 points per game in last year's Math Hoops season. This year he has increased his scoring by 30%. What is his new average score per game?
Step 1
We find how many points the score increase by
The percentage increase = 30%
Hence:
30% × 35 points
= 10.5 points
Step 2
His new average score =
Former score + increase
= 35 + 10.5
= 45.5 points per game
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
Answer:

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)

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
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%
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?
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

Paul is getting balloons for his uncle's birthday party. He wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Paul wants to get 46 balloons, how many yards of string will he need
Answer:
Paul needs 276 feet of string for his uncle's birthday party.
Step-by-step explanation:
From the problem we are given, we can simply break it down as follows:
Paul wants each balloon string to be 6 feet long.
Paul also wants to get 46 balloons with each of them having 6-feet long strings attached to them.
This means that Paul will need 6 feet ling strings 46 times (that is for all the 46 balloons)
to solve this mathematically, we multiply 46 X 6 to get 276 feet.
Therefore, Paul needs 276 feet of string for his uncle's birthday party.
