Answers
1)The average height of 4 boys is 1.65m. One boy is 1.68m tall. Find the average height of the other 3 boys.
2) Ian, John and Juan shared a sum of money in the ratio 4:7:9. What percentage of the sum of money did John receive?
3) The usual price of a refrigerator is $800. It is sold at a discount of 15%.find the selling price.
Answers
If the average height of the 4 boys is 1.65m that means the total of their heights is 6.6m
To get the average height of the other 3 boys you have to take away the one boys height from the total and divide that number by 3
6.6-1.68 = 4.92
4.92/3 = 1.64
Therefore the average height of the other three boys is 1.64m
2)
To do this you first find the total of the parts of the ratio so
4+7+9 = 20
Next you find what percentage each part is worth so
100/20 = 5
This means that each part of the ratio is worth 5% of the total sum
Because John received the 7 in the 4:7:9 ratio you times 7 by 5
7x5 = 35
Therefore John got 35% of the total sum of the money
3)
The formula for finding the discounted price using the percentage discount is
Discounted Sale price = (100% - %Discount) x Regular Sale Price
Using this formula to find the discounted sale price you do
(100% - 15%) x 800
= 85% x 800
= 680
Therefore the selling price of the refrigerator is $680
please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answers
Answer: -5/8 + 3/4 = 1/8
Step-by-step explanation:
The final result after simplifying is 1/8. So, the sum of -5/8 and 3/4 on the number line is 1/8.
Step 1: Start at -5/8
On the number line, locate the point corresponding to -5/8. Since the increments are in 1/8, count 5 units to the left from 0, which lands you at -5/8.
Step 2: Move 3/4 units to the right
Now, you need to add 3/4 to the -5/8 value. To do this, move 3/4 units to the right from the starting point of -5/8. Since the increments are in 1/8, you need to move 3 x 1/8 = 3/8 units to the right.
-5/8 + 3/4 = -5/8 + 3/8
Step 3: Simplify the sum
To add -5/8 and 3/8, you need a common denominator, which is 8. So, you can rewrite 3/4 as 6/8 (by multiplying the numerator and denominator by 2):
-5/8 + 6/8 = ( -5 + 6 ) / 8 = 1 / 8
The final result after simplifying is 1/8. So, the sum of -5/8 and 3/4 on the number line is 1/8.

Answer:
1. 1,200
2. 6
3. 0.0
4. -0.01187
5. 29.94065
6. 300,000
7. 35,999.9980
8. -239.4065
Step-by-step explanation:
1. 7 Days in a Week
(3 x 7) - 12 = 24 - 12 = 12
The question asks for the answer to be in the thousands place, which is (_,xxx.x)
Hence, 1,200 is the answer.
2. difference means subtract
(5-2) + 3 = 3 + 3 = 6
The answer is 6 because it says the ones place, which is (x_.x)
3. The answer is 0.0
You do not even have to do the math because multiplying by 0 will always equal 0, but since it asks for the answer in the tenths place (x._), then the answer is 0.0
4. To start, there are 28 days in February, on a non-leap year.
There are 2 days in one weekend.
28-2 = 26
Next, the problem says divide by 2
26/2 = 13
Then, the problem says subtract the number in the thousands place, being 1,200, from the 13.
13 - 1,200 = -1187
FInally, the question asks us to put the answer in the hundredths place, which is (x.x_ ).
The final answer is -0.01187
5. Tenth Place = 0.0
Hundredths Place = -0.01187
Ones Place = 6
The problem is asking for the tenth, ones, and hundredth place to all be added up.
0.0 + ( - 0.01187) + 6 = 5.98813
Then, the problem asks us to divided the answer, being 5.98813, by 2
5.98813/2 = 2.994065
Finally, the problem asks for us to put the answer in the the tens place, which is _x.x.
Therefore, the answer is 29.94065
6. To start, there are 24 hours in one day
(24 x 2) = 48
Then the problem asks for us to divide 48 by 16
48/16 = 3
Finally, the problem asks for us to put the answer in the hundred thousands place, which is (_xx,xxx.x)
Therefore, the answer is 300,000.
7. Hundred Thousands Place = 300,000
Thousands Place = 1,200
The problem is asking us to multiply the hundred thousands place, being 300,000 by the thousands place, being 1,200.
300,000 x 1,200 = 360,000,000
Then, the problem is asking to subtract 12 from that answer, being 360,000,000.
360,000,000 - 20 = 359,999,980
Finally, the problem is asking to put the answer in the ten thousands place, which is (x_x.xx)
The answer would be 35,999.9980.
8. Tens Place = 29.94065
Ones Place = 6
The problem is asking to subtract the number in the tens place, being 29.94065, from the number in the ones place, being 6.
6 - 29.94065 = -23.94065
Finally, the problem asks for the answer to be written in the hundred place, which is (x_xx.xx).
Therefore, the answer is -239.4065
Answer:
Step-by-step explanation:
(1) Number of days in a week = 7
(3*7) - 12
= 21-12
= 9
9 in thousands place --> 9*1000 = 9000
(2) Difference of 5 and 2 = 5-2 = 3
Now, add 3
3 + 3 = 6
6 in ones place --> 6*1 = 6
(3) Any number multiplied by 0 = 0
So, 0 in tens place --> 00
(4) Number of days in a weekend = 2
Number of days in Feb (non-leap) = 28
Difference = 28-2 =26
∴ 26÷2 = 13
(5) \(\frac{\frac{1}{10}+ \frac{1}{100}+ 1 }{2}\)

141
Answer:
They made 45 dollars the first day, 53 dollars the second day, and 43 dollars the third day. In total the made 141 dollars.
Step-by-step explanation:
For the first day you multiply the goal amount by the decimal or fraction that represents the percentage to get your answer. So it would be:
50 x 0.90 = 43For the second day you do the same as above, but once you get the answer to that step, you add fifty to it. You can also do it all in one step. It would look like:
50 x 0.06 = 33 + 50 = 53OR
50 + (50 x 0.06) = 53For the third day you would do the same as you did for the first day, then you would take that answer and subtract it from fifty. You can do this all in one step too. It should look like this:
50 x 0.14 = 750 - 7 = 43OR
50 - (50 x 0.14) = 43Then to get your final answer, you would just add all of the days up like this:
45 + 53 + 43 = 141So your answer would be 141 dollars, or $141.00

What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday.
Therefore in total, Mike read (2/4 + 1/3) of the book.
= (6 + 4)/12.
= 10/12.
= 5/6 of the book.
Also given, Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday.
Therefore in total, Andy read (1/2 + 1/5) of the book.
= (5 + 2)/10.
= 7/10.
As the fractions (2/4) which Mike read and (1/2) Andy read they have read the same amount of the book but in the next time Mike read 1/3 of the book and 1/5 and we know 1/3 is greater than 1/5.
So, Mike read more of the book than Andy.
