Step-by-step explanation:
solve for n in the proportion. n/40=27/36. n=?
Answer:
n=30
Step-by-step explanation:
40/36=1.111111
1.111111 times 27=30
Answer:
n=30
Step-by-step explanation:
solve by simplifying both of the equations , the isolating the variable
Reduce the fraction with 9 27/36 divide top and bottom by 9 = 3/4
n/40=3/4 cross multiplication 4n = 120 ( divide both sides by 4 )
n=30
Simon wants to build a cube-shaped storage container that holds 125 cubic feet of water for some frogs he recently purchased.Using the formula, V=s3, where represents the volume of the container and represents its side length, find the length of one side of the container.
Answer:
Length of one side of the container = 5 feet
Step-by-step explanation:
Given:
V = s³
Where,
V = volume of the container
s = side length of the container
V = 125 cubic feet
Find s?
V = s³
125 = s³
Find the cube root of both sides
3√125 = 3√s³
5 = s
s = 5 feet
Length of one side of the container = 5 feet
Madison is a high school basketball player. How many points would Madison score in a game if she made 8 free throws (worth one point each) and 6 three point shots?
How many points would Madison score in a game if she made x free throws and y
three point shots?
Answer:
26 and 1x+3y on Delta math
Step-by-step explanation:
Explanation:
Each free throw scores 1 point, so 8 free throws would score 1\times 81×8 or 8 points. Each three point shot scores 3 points, so 6 three point shots would score 3\times 63×6 or 18 points. Therefore, the total number of points Madison would score is 26.

Let f(x)=6/5x−1/2. Describe the transformations from the graph of f to the graphs of g(x)=−f(x) and h(x)=f(−x).
Answer:
g(x)=-6/5x+1/2
h(x)=-6/5x-1/2
Step-by-step explanation:
1). g(x)=−f(x) ?
f(x)=6/5x−1/2
g(x)=−(6/5x−1/2)
g(x)=-6/5x+1/2
2). h(x)=f(−x) ?
f(-x)=6/5(-x)−1/2
f(-x)=-6/5x-1/2
h(x)=-6/5x-1/2

The equation y = 1.2x represents the rate, in beats per second, that Lee's heart beats. The graph represents the rate that Nancy's hear beats. Determine whose heart is beating at a faster rate.
Answer:
Nancy's heart rate is higher than Lee's heart rate.
Step-by-step explanation:
Equation for the heart beats of Lee is,
y = 1.2x
And the heart beats of Nancy is represented by the graph.
Higher the slope of the line = Faster the hear rate.
Slope of line represented by y = 1.2x,
m = 1.2
Similarly, slope of the line given in the graph = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{5}{4}[/tex]
= 1.25
Since, slope of the line representing Nancy's heart rate is greater than slope of the line representing Lee's heart rate.
Therefore, Nancy's heart rate is faster than Lee's heart rate.
the height of an apple
Answer:
apples are usually roundish, 5–10 cm (2–4 inches) in diameter
Step-by-step explanation:
Dwarf apple trees grow about 10 feet tall, while semi-dwarf varieties can reach 15 feet. Meanwhile, standard-size apple trees often soar to heights above 20 feet and sometimes tower at 30 feet.
Apples are 5 - 10 cm in height.
What is height?Height, altitude, elevation mean vertical distance either between the top and bottom of something or between a base and something above it
Given is an apple.
When harvested, apples are usually roundish, 5–10 cm (2–4 inches) in diameter.
Therefore, apples are 5 - 10 cm in height.

Tom has a fair spinner with six sides. They are labelled red, red, blue, green, red, blue. Choose the word that best describes the likelihood that the spinner will land on a colour not green.
Answer:
It is MOST LIKELY NOT going to land on green.
Step-by-step explanation:
Since the spinner has 6 sides, the total possible outcome is 6. There are 3 reds, 2 blues and 1 green.
The probability that the spinner will land on a green is [tex]\frac{1}{6}[/tex]. But since we are looking for the probability that it won't land on green, we have [tex]1 $-$ \frac{1}{6} = \frac{5}{6}[/tex]
From here we can best describe the likelihood that the spinner will land on a colour not green as: it is MOST LIKELY NOT going to land on green
The total U.S. apple production increased during the 1973-1988 period from 6.2 to 9.l billion pounds. To the nearest tenth of a percent, what was the percent of increase in apple production in the United States from 1973-1988? plzzzzz help
Subtract to find the difference in the amounts:
9.1 - 6.2 = 2.9
Divide the change by the starting amount:
2.9/6.2 = 0.46774
Multiply by 100 to get the percentage and round to the nearest tenth:
0.46774 x 100 = 46.8 %
Answer: 46.8%
-12x+3y=24
1) y= -4x + 8
2) y= 4x - 8
3) y= 4x + 8
4) y = -4x -8
-12x+3y=24
(get y alone on the left)
3y=12x+24
(divide by 3)
y= 4x+8

4-k=p/x
-4 = -4
-k=p/x-4
k=4-p/x
Step-by-step explanation:
Answer:
k = - 4 + p
Step-by-step explanation:
p = x ( 4 - k )
p = 4x - kx
-4x -4x
4x - p = - kx
divide by -x
-k = 4 - p
divide by -
k = - 4 + p

Suppose A gas station monitors how many bags of ice they sell along with the maximum daily temperature for 100 days. A gas station data analysis plots the data in a scatterplot with temperature, in degrees Fahrenheit, on the horizontal axis and the number of bags of ice sword on the vertical axis. She calculates a linear correlation coefficient of r= 0.9972. The mean Temperature is 83.8959 degrees Fahrenheit with a standard deviation of 11.2921 Degrees Fahrenheit. The mean number of ice bags sold is 70.3873 with a standard deviation of 27.8 913.
Answer:
hello your question is incomplete attached below is the complete question
answer :
a ≈ - 136
b = 2.46
Step-by-step explanation:
A) we apply the formula for slope in regression
b = r * [tex]\frac{Sy}{Sx}[/tex] --------- ( 1 )
where:
standard deviation (Sy) = 27.8913
standard deviation ( Sx ) = 11.2921
Linear correlation coefficient ( r ) = 0.9972
substitute given values into equation 1
b = 2.46
for intercept A
a = Y - b * X --------- ( 2 )
Mean number of ice bags sold ( Y )= 70.2873
b = 2.46
Mean temperature ( X )= 83.8959
substitute given values into equation 2
a = 70.2873 - ( 2.46 * 83.8959 )
= - 135.997

What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus, we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto XYZ,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x, y, z will perfectly match with transformed ABC
Hence, The correct answer is vertex B to vertex Y
