Answer:
12 and 16.
Step-by-step explanation:
Let both positive numbers be x and y.
3/4 = x/y....... equation 1
x² + y² = 400..... equation 2
From equation 1
3/4 = x/y
Cross multiply
3y = 4x
Divide both sides by 3
y = 4x/3
Substitute y = 4x/3 into equation 2
x² + y² = 400
x² + (4x/3)² = 400
x² + 16x²/9 = 400
Multiply through by 9
9x² + 16x² = 3600
25x² = 3600
Divide both sides by 25
x² = 3600/25
x² = 144
Take the square root of both sides
x = √144
x = 12
Substitute x = 12 into equation 1
3/4 = x/y
3/4 = 12/y
Cross multiply
3y = 12 x 4
3y = 48
Divide both sides by 3
y = 48/3
y = 16
If the x-value repeats and the y does not, is it a function?
Answer:
If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.
For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats
a function because no x value is repeating the x value is known as an independent value. Does that make sense?
"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.
For a relation to be called a function, the following holds true:
Each x-value (input) has it's own unique y-value (output).
A x-value cannot give two different y-values.
If an x-value repeats, the corresponding y-value must repeat.
Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

The cost of 10 balls is 280. Find the cost of 19 balls.
Answer:
$532
Step-by-step explanation:
Hey There!
So to solve this problem the first thing that we want to do is find the cost of 1 ball
To do so we divide the total cost of 10 balls by 10
280/10=28 so each ball cost 28
now to find the cost of 19 balls we multiply the cost of 1 ball by 19
18x28=532
thus meaning 19 balls cost $532
Answer:
$532
Step-by-step explanation:
We need to find the cost of 1 ball and then multiply it by 19, here is the math:
280/10=28
Now we know that 28 is the cost of 1 ball.
28 x 19=532
The cost of 19 balls is $532

Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?
Answer:
The amount of pages that remain to be read is 150 pages
Step-by-step explanation:
Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.

Find the value of the variable
Answer:
x=6
Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6
a) What type of correlation is shown in diagram A?
b) What type of correlation is shown in diagram B?
c) What type of correlation is shown in diagram C?
Answer:
A = strong negative correlation
B = positive correlation
C = very weak or no correlation
Step-by-step explanation:
Scatter plot A:
A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.
Scatter plot B :
Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.
Scatter plot C :
From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

Label the diagrams that show these two methods for calculating 19x50
At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?
Answer:
Kirby Middle School
The percentage of students who used Snap the most is given as:
= 44%
Step-by-step explanation:
a) Data and Calculations:
App Number of Students
Face 8
Snap 22
Insta 20
Total 50
The percentage of Snap users = Number of Snap users/Total users * 100
= 22/50 * 100 = 44%
b) This represents the proportion of all the students surveyed about the use of social media app. Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap. This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.
