The length of a rectangle swimming pool is 3 1/4 yards. If the area is 9 3/4 square yards, what is the width of the swimming pool?
A- 3 yards
B- 31 11/16 yards
C- 6 1/2 yards
D- 2 3/4 yards
Answers
Answer:
Let's start by using the formula for the area of a rectangle:
area = length x width
We know that the length is 3 1/4 yards and the area is 9 3/4 square yards, so we can substitute those values in and solve for the width:
9 3/4 = (13/4) x width
To isolate the variable, we can multiply both sides by the reciprocal of 13/4, which is 4/13:
(9 3/4) x (4/13) = (13/4) x (4/13) x width
3 = width
Therefore, the width of the swimming pool is 3 yards, which is option A.

Answer:
$6.19
Step-by-step explanation:
You want the difference in price per pound between the cost of salmon at store B and the cost at store A.
Cost per poundThe cost per pound is found by dividing the cost by the corresponding number of pounds. The difference in cost will be the difference of those quotients.
cost at Store B - cost at Store A = ($21.36/(2 lb)) -($8.98/(2 lb))
= ($21.36 -8.98)/(2 lb) = $6.19/lb
It is $6.19 per pound more expensive to buy salmon at Store B than at Store A.

The following scatter plot represents the scores of thirteen students on a geography test compared to the number of hours that each student studied for the test. Use the line of best fit to predict the score of a student who studied three hours for the test.
Answers
Answer:
95
Step-by-step explanation:
Looking at the graph, we can find the red line. The red line passes through the following coordinates (x,y): (0,65), (1, 75), (2, 85) and (3,95).
We know that x is the number of hours studied, and y is the score. If x=3, and y=95, then a student that studied three hours for the test will most likely score 95%.

Where would -4,9 be on a coordinate grid
A-1st
B-2nd
C-3rd
D-4th
Answers
The x-coordinate represents the horizontal position of the point, while the y-coordinate represents the vertical position of the point.
In this case, the x-coordinate is -4, which means the point is 4 units to the left of the origin. The y-coordinate is 9, which means the point is 9 units up from the origin.
Therefore, the point (-4,9) is located in the 2nd quadrant of the coordinate grid, since it is to the left of the origin (in the negative x-direction) and above the origin (in the positive y-direction).
So, the correct answer is B-2nd.
Triangle UVW has vertices at U(−2, 0), V(−3, 1), W(−3, 3). Determine the vertices of image U′V′W′ if the preimage is rotated 90° counterclockwise.

B:U′(0, −2), V′(1, −3), W′(3, −3)
C:U′(2, 0), V′(3, −1), W′(3, −3)
D: U′(−2, 0), V′(−3, 0), W′(3, −3)
Answers
x' = -y
y' = x
For each vertex (x, y) in the original triangle, we can apply this formula to get the corresponding vertex in the image.
Let's start with vertex U(-2, 0):
x' = -y = 0
y' = x = -2
So, U' is at (0, -2).
Now, let's consider vertex V(-3, 1):
x' = -y = -1
y' = x = -3
So, V' is at (-1, -3).
Finally, let's consider vertex W(-3, 3):
x' = -y = -3
y' = x = 3
So, W' is at (-3, -3).
Therefore, the vertices of the image triangle U'V'W' are (0, -2), (-1, -3), and (-3, -3).
Thus, the correct answer is option A: U′(0, −2), V′(−1, −3), W′(−3, −3).

Answer:
A
Step-by-step explanation:
i think its (A) let me know if im wrong sorry if you get it wrong
Answer:
Look Down
Step-by-step explanation:
To determine the location with the most consistent temperature, we should use a measure of variability that takes into account the spread of the data. The interquartile range (IQR) is a good measure of variability to use because it is less sensitive to extreme values than the range.
Option A states that IQR should be used because sunny town is skewed. However, whether the data is skewed or not does not affect the choice of measure of variability.
Option B states that IQR should be used because desert landing is symmetric. However, whether the data is symmetric or not does not affect the choice of measure of variability.
Option C states that range should be used because sunny town is skewed. However, range is not a good measure of variability to use for skewed data because it is sensitive to extreme values.
Option D states that range should be used because desert landing is symmetric. However, range is not a good measure of variability to use for any type of data because it is sensitive to extreme values.
Therefore, the correct answer is A: IQR, because it is a good measure of variability to use for any type of data, including skewed data like in sunny town.

y = 2x + 5
y equals one fifth times x minus 7
y equals negative one fifth times x
y = −5
Answers
Answer:
y = (-1/5)x
Step-by-step explanation:
The equation that represents a proportional relationship, or a line, is
y = k x , where is the constant of proportionality.
y = 2x + 5 (N0)
y equals one fifth times x minus 7 ------- y = (1/5)x -7 (No)
y equals negative one fifth times x ------y = (-1/5)x (Yes)
y = −5 (No)
Answer:D -> y equals one fifth times x minus 7
Step-by-step explanation: In a proportional relationship, when x is multiplied by a constant, then y will also be multiplied by the same constant. This means that the ratio between x and y remains constant throughout. In the given options, the equation "y equals one-fifth times x minus 7" follows the proportionality rule because when x is multiplied by 5, then y is also multiplied by 5, which means that the ratio between x and y remains constant throughout. Therefore, the correct option is "y equals one-fifth times x minus 7
Anthony measures the height of a plant at the beginning and the end of summer. Beginning of summer in June the pant was 12 3/8 inches but at the end of summer in September the plant was 14 inches.
PT1.A. How many inches did the plant grow?
PT2.B. Anothony planted the seed in March. How much did the plant grow per month prior to him measuring in June?
ANSWER BOTH QUESTIONS A AND B
Answers
PT1.A — 1 5/8 (1.625) inches
PT2.B — 2 7/16 (2.4375) inches
Step-by-step explanation (PT1.A):Height of the plant in the Beginning of summer = 12 3/8 inches
Height of the plant at the End of summer = 14 inches
Growth of the plant = Height of the plant in the Beginning of summer - Height of the plant at the End of summer.
Growth of the plant = 14 - 12 3/8
= 14 - 99/8
= 112/8 - 99/8
= 13/8
= 1 5/8 inches
= 1 + 0.625 (Decimal)
= 1.625 inches (Decimal)
You can write the answer as 1 5/8 inches or 1.625 inches. I just converted the fraction into a decimal.
As we can observe from the previous question, Anothony planted the seed in June and it grown 1 5/8 (1.625) inches by September.
Height of plant grown = 1 5/8 (1.625) inches
Number of months from June to September = 2 months
Height of plant grown per month = Height of plant grown / Number of months from June to September
Height of plant grown per month = 1 5/8 (1.625) / 2
= 13/8 (1.625) / 2
= 13/16 (0.8125) inches
So, the plant grows 13/16 (0.6125) inches per month.
Number of months from March to June = 3 months
Height of plant grown per month = 13/16 (0.8125) inches
Growth of plant grown from March to June = Number of months from March to June * Height of plant grown per month
Growth of plant grown from March to June = 3 * 13/16 (0.8125)
= 39/16 (2.4375)
= 2 7/16 (2.4375) inches

The other equations all represent linear equations. A linear equation is written in the form y = mx+b (slope-intercept form) where m is the slope and b is the y-intercept. All of the other equations given will simplify to this form when we isolate the y-variable.

Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
Answers
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

the odds the yankees don't get rain is 3/5. The odds they win are 3/4. 3/5x3/4=9/20
Answer:
(C), 9/20
Step-by-step explanation:
If the probability that the next Yankees game will be rained out is 2/5, this must mean than, theoretically, two times out of five, the game will be rained out.
This also means than three times out of five, it will not be rained out, so the probability that it will not be rained out is 3/5 (1-(2/5)=3/5)
We know that the probability that they will win their next game is 3/4.
We need to find the probability that it doesn't rain and the Yankees win. TO do this, we multiply both probabilities together. So, we have:
[tex]\frac{3}{5} *\frac{3}{4} =\\\\\frac{9}{20}[/tex]
So, the answer is (C), 9/20.
