What is the solution to the equation 9r=4/7
Answers
Answer:
r=4/63
Step-by-step explanation:
Divide each term in 9r=47 by 9 and simplify.
Answer:
[tex]r=\frac{4}{63}[/tex]
Step-by-step explanation:
1) Divide both sides by the same factor
[tex]9r=\frac{4}{7}[/tex]
[tex]\frac{9r}{9} =\frac{\frac{4}{7} }{9}[/tex]
2) Simplify
Cancel terms that are in both the numerator and denominator[tex]\frac{9r}{9} =\frac{\frac{4}{7} }{9}[/tex]
[tex]r=\frac{\frac{4}{7} }{9}[/tex]
Divide the numbers[tex]r=\frac{\frac{4}{7} }{9}[/tex]

Answers
Answer:
y = -x + 3
Step-by-step explanation:
1. Substitute "y = -x + 3" in for y in the second expression:
2x + 2(-x + 3) = 6
2. Simplify:
2x + (-2x) + 6 = 6
0 + 6 = 6
6 = 6
Because the values are equal, the solution of y = -x + 3 is a valid input.

The regression line is not a good model because the residuals are not randomly distributed.
What is the residual plot?For a residual plot to represent a good model, the points on the residual plot must be randomly distributed across the coordinates.
From a regression, the residual is the difference between the observed values and the predicted values.
Using the graph, we can see that the points that follow a pattern (or curve) regression line is not a good model because the residuals are not randomly distributed.

According to the triangle sum theorem, the three interior angles of any triangle add up to 180 degrees. So, if we add up the three angles given, to be a triangle, they have to add up to 180 degrees.
38 + 42 + 110 = 190
So, ( (1) 38, 42, 110 ) is not a triangle becuase it adds up to more than 180 degrees (1).
20 + 40 + 120 = 180
So, ( (2) 38, 42, 110 ) is a triangle because it adds up to 180 degrees (2).
For the lengths for a triangle, the length of one side of a triangle must be greater than the difference and less than the sum of the lengths of the other two sides. This is saying:
A-B < C
A+B > C
So to find if they can be, simply plug in the values.

C. 54
D. 72
Answers
The volume of the rectangular prism filled with unit cubes each measuring the value of the length given is 72ft³.
Hence, Option D) 72ft³ is the correct answer.
Rectangular Prism and Cube
A rectangular prism is simply a three-dimensional solid shape with six faces which are rectangles.
The volume of a rectangular prism is expressed as;
V = l × w × h
Where l is length, w is width and h is height of the prism
A cube is a three-dimensional solid with six equal square-shaped sides.
Given the data in the question;
Length of the sides of the cube = 1 footLength of the rectangular prism l = 4 cubes × 1 foot = 4ftWidth of the rectangular prism w = 3 cubes × 1 foot = 3ftHeight of the rectangular prism l = 6 cubes × 1 foot = 6ftTo determine the volume of the rectangular prism, we substitute our given values into the expression above.
V = l × w × h
V = 4ft × 3ft × 6ft
V = 72ft³
Option D) 72ft³ is the correct answer.
Hence, the volume of the rectangular prism filled with unit cubes each measuring the value of the length given is 72ft³.
Amanda and Molly are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Amanda sold 3 rolls of plain wrapping paper and 3 rolls of shiny wrapping paper for a total of $60. Molly sold 1 roll of plain wrapping paper and 9 rolls of shiny wrapping paper for a total of $132. What is the cost each of one roll of plain wrapping paper and one roll of shiny wrapping paper? (no links please)
Answers
Answer:
Step-by-step explanation:
Solving system of symultaneous equation:
Let the cost of one roll of plain wrapping pair = x
Let the cost of one shiny wrapping paper = y
Amanda:
Cost of 3 rolls of plain paper + cost of 3 rolls of shiny paper = $ 60
3*x + 3*y = 60
3x + 3y = 60 ------------------(I)
Molly:
Cost of 1 roll of plain paper + cost of 9 rolls of shiny paper = $ 132
x + 9y = 132 ---------------------(II)
x = 132 - 9y ---------------(III)
Substitute x = 132 -9y in equation (I)
3*(132-9y) + 3y = 60
3*132 - 3*9y + 3y = 60
396 - 27y + 3y = 60
Combine like terms
396 - 24y = 60
Subtract 396 from both sides
-24y = 60 - 396
-24y = -336
Divide both sides by (-24)
y = -336/(-24)
[tex]\sf \boxed{y=14}[/tex]
Now, substitue y = 14 in equation (III)
x = 132 - 9*14
= 132 - 126
[tex]\sf \boxed{x = 6}[/tex]
cost of one roll of plain wrapping paper = $ 6
Cost of one roll of shiny wrapping paper = $ 14

Answers
Answer:
I believe it is 1/9 or 11.1%
Step-by-step explanation:
11/99 /(divided by) 11 = 1/9
1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)
so as a percent, it makes it 11.1% (repeating) or 11 [tex]\frac{1}{9}[/tex]% (which is a more exact solution)
now if you need a ratio, it would be 1:9

Answer:
1/12 + 3/12 = 4/12 (or 1/3)
Step-by-step explanation:
we want to express
1/12 + 1/4 as 1/12 + something / 12
1/12 + 1/4 = 1/12 + something/12
we already have the 1/12 part, so we're left with
1/4 = something / 12
first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3
then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.
3/3 = 1
1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12
thus, our second value is 3/12
we then have 1/12 + 3/12
if we have the same denominators, we can simply add the numerators up
1/12 + 3/12 = (1+3)/12 = 4/12

Answers
Answer:
150 cm²
Step-by-step explanation:
Given
Perimeter = 60 cmHypotenuse = 25 cmSolving
We need to find the lengths of the altitudesSince 25 cm is already covered there is (60 - 25) = 35 cm remainingThe lengths can be taken as x and 35 - xNow, since it's a right triangle, we can solve for x using the Pythagorean TheoremApplying the theorem
x² + (35 - x)² = 25²x² + 1225 - 70x + x² = 6252x² - 70x + 600 = 0x² - 35x + 300 = 0x = 35 ± √1225 - 4(1)(300) / 2x = 35 ± √25 / 2x = 35 ± 5 / 2x = 40/2 = 20 or x = 30/2 = 15Upon solving the lengths of the altitudes are 15 and 20Area of the triangle

What is the Range and Interquartile Range of a Data Set?Range = Maximum value - minimum value
Interquartile range (IQR) = Q3 - Q1
Range and IQR are both measures of variability. The larger the value, the more spread the data values in a data set are.
Range for Arnold's training times = 102 - 84 = 18
Range for Jackson's training times = 103 - 83 = 20
Therefore, Jackson's training times had the greatest spread.
Interquartile range for Arnold's training times = Q3 - Q1 = 99 - 87 = 12
Interquartile range for Jackson's training times = Q3 - Q1 = 100 - 87 = 13
Thus, Arnold's middle 50% of his training times had the least spread.
The range and interquartile range tells us that, Arnold's training times are more consistent than Jackson's.
