Answer:
y = 7
Step-by-step explanation:
Opposite sides are the same length:
LM = NO
2y -9 = y -2
y = 7 . . . . . . . add 9-y to both sides
What is the inverse of y= 3/2x -2
Answer:
f^-1(x) = (2x + 4) / 3
Step-by-step explanation:
- switch 'y' with 'x'
x = 3/2y - 2
- solve for 'y'
x + 2 = 3/2y
- multiply each side by 2
y = (2x + 4) / 3

The radius of a circle is 9 centimeters. What is the length of a 96° arc?
Wrong answer but unique technique to consider: i think i inversed the ratio but i think its right
Pi = circumference/diameter
X/18 centimeters =pi
X is whole circumference 18pi cm you need to convert radians to degrees and get partial arc1 pi is 180 degrees so ratio of
Was the error inverse ratio 96/180?
180/96*18
Error here factor of 72 not 96
18*2*3*3*10/2*3*12 [edit factor should be 2 4 12 ]cancel out factors to reduce
180/4 =45cm
Correction
180*3/4*4
So answers i got are 45 cm corrected as 33.75 cm still way more than total circumference of 18pi 56cmapprox and 9.6cm both are wrong according to calculator online
Please note I canceled out pi by using is degree ratio
Double check i may be wrong
Step-by-step explanation:
Answer:
Solution, we have,
Degree measure ([tex]\theeta[/tex][tex]\alpha[/tex]) = 96° = 96[tex]\pi[/tex]/180
Radius (r) = 9cm
Length of arc (l) = ?
Now,
∝ = l /r
or, [tex]\frac{96\pi }{180}[/tex] =[tex]\frac{l}{9}[/tex]
or, l =[tex]\frac{(96\pi )(9)}{180}[/tex] =4.8[tex]\pi[/tex]cm

The circumference of a circle is 6π ft. What is the area, in square feet? Express your answer in terms of
π
Please help
Answer:
Circumference of the circle 2π(radius)=6π ft
Therefore, radius=3 ft
Area=π(radius)²=π×3²=9π ft²
9π ft² is the right answer.
The area of circle is 9π square feet.
What is area?Area is the amount of area occupied by an object's flat (2-D) surface or shape.
The circumference of circle = 2πr
6 = 2πr
r = 3π
And the area of circle is πr².
The area of the circle = 9π
Therefore, the area of the circle is 9π square feet.

I need help on listing the four points that have a distance of 8 from B, thank you!
Answers:
(12, 3)(-4, 3)(4, 11)(4, -5)A diagram is shown below.
===========================================================
Explanation:
First we locate point B at (4,3). The '4' in the x position means we've gone 4 units to the right of the origin, and the 3 in the y coordinate means we've gone 3 units up.
Now we need to find four points that are 8 units away from this central location. We'll ignore point A.
What we can do is add 8 to the x coordinate of point B to get x+8 = 4+8 = 12. Keeping the y coordinate the same, the point (12, 3) is exactly 8 units away from (4,3). Think of drawing a number line through those two points. Then we can note there are 8 spaces between (4,3) and (12,3). Or we can say "there are 8 spaces between 4 and 12" since that '3' doesn't really play much of a role in this case.
So (12,3) is one answer.
---------------------------------
Move back to point B(4,3)
Instead of adding 8 to the x coordinate, let's subtract 8 from it
x-8 = 4-8 = -4
Again the y coordinate is kept the same.
The point (-4, 3) is 8 units away from (4,3). The number line distance from -4 to 4 is 8 units.
So (-4,3) is another answer.
----------------------------------
Move back to point B
From this starting point, we can move 8 units up. Doing this means we add 8 to the y coordinate, while the x coordinate is kept intact.
(4,3) turns into (4,11) after doing so.
(4,11) is another answer.
---------------------------------
Move back to point B
From this point, we can move down 8 units to arrive at (4,-5). note how y-8 = 3-8 = -5. The x coordinate is kept the same.
(4,-5) is another answer.
----------------------------------
The four points we found were:
(12, 3)(-4, 3)(4, 11)(4, -5)which are four possible answers
Those points are found by going 8 units right, 8 units left, 8 units up and 8 units down in that order. Each time we started at point B as our center of operation. The use of the word "center" is done because we can form a circle of radius 8, and the center of the circle is at B(4,3). Any point on the circle's edge is exactly 8 units away from the center point B.
Refer to the diagram below. The four answers are the red points P,Q,R,S. The point T is another point that could be an answer, but it's not as easy to find compared to the four other points.
Jeremie bought 5 pounds of bananas for $4.45. How much is 1 pound of bananas? Show or explain your reasoning
what is the strategies for this math problem?
Answer:
1 pound of bananas is 0.89
Step-by-step explanation:
Money over quantity 4.45/5
that means you divide so heres the layout
4.45/5 = x/1 so that is
5x=4.45 divide 5 so that gives us our variable 5÷5 that cancels out five 4.45 divide by 5 is 0.89
so for every pound of bananas is 0.89

PLEASE ANSWER THIS QUESTION RIGHT Name the x-intercept(s)?
A:0 and 4,B:2,C:4,D:0.
Answer:
A. 0 and 4
Step-by-step explanation:
The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.
Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.
x-intercepts are 0 and 4.

Step-by-step explanation:
The line crosses grid intersections at (-1, 2), (1, -1) and (3, -4). These points are separated by 2 units horizontally and 3 units vertically.
The rise (vertical change) is -3 for each run (horizontal change) of +2, so the ratio rise/run is -3/2. That is the slope of the line: -3/2.

In a random sample of 60 computers, the mean repair cost was $150. Assume the population standard deviation is $36. Construct a 95% confidence interval for the population mean.
Answer:
The 95% confidence interval for the population mean is between $140.89 and $159.11.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{36}{\sqrt{150}} = 9.11[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 150 - 9.11 = $140.89
The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11
The 95% confidence interval for the population mean is between $140.89 and $159.11.

Answer:
Length of mammoth's tusk in poster = 15.33
Step-by-step explanation:
Actual height of mammoth = 10 feet 5 inches = 126 inches
Height on the poster of mammoth = 14 inches
Actual length of mammoth's tusk = 11.5 feet = 138 inches
Length of mammoth's tusk in poster = x
126 : 14 :: 138 : x
Product of mean = product of extremes
x * 126 = 14 * 138
[tex]x = \frac{14*138}{126}[/tex]
x = 15.33

What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
Let the area of the 2 triangles be T
Let the area of the 2 rectangles be R
Let the area of the third side be U
Now , the total surface area of the prism = T + R + U
where T = 2 x ( 1/2 ) ( 16 x 12 )
T = 192 cm²
R = ( 16 x 10 ) + ( 12 x 10 )
R = 280 cm²
And , U = 20 x 10
U = 200 cm²
Therefore , the total surface area of prism S = 192 cm² + 280 cm² + 200 cm²
S = 672 cm²
Hence , the surface area of prism is S = 672 cm²

What is the area of an rectangle with sides lengths of 5/12 foot and 2/3 foot
Answer:
The area of given rectangle is 5/18 square feet.
Step-by-step explanation:
Let l be the length of rectangle and w be the width of the rectangle.
Given information is:
Length = l = 5/12 foot
Width = w = 2/3 foot
The area of a rectangle is given by the formula
[tex]Area = Length*Width\\A = l*w[/tex]
Putting the values for width and length
[tex]A = \frac{5}{12} * \frac{2}{3}\\= \frac{10}{36}\\=\frac{5}{18}[/tex]
The area is 5/18 square feet.
Hence,
The area of given rectangle is 5/18 square feet.
