Answer:
Please check the explanation.
Step-by-step explanation:
Given the table
Minutes 6 15 27
Pages 20 50 90
Given two points to find the slope
(6, 20)(15, 50)Finding the slope between (6, 20) and (15, 50)
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [50 - 20] / [15 - 6]
= 30 / 9
= 10/3
Thus, the slope = m = 10/3
Using the point-slope form of the linear line function
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 10/3 and the point (6, 20)
[tex]y-20=\frac{10}{3}\left(x-6\right)[/tex]
Add 20 to both sides
[tex]y-20+20=\frac{10}{3}\left(x-6\right)+20[/tex]
[tex]y=\frac{10}{3}x-20+20[/tex]
[tex]y=\frac{10}{3}x[/tex]
Therefore, the rule relating the minutes, x, to the number of pages, y.
[tex]y=\frac{10}{3}x[/tex]
Determining the number of pages when the minutes equal 72
We already got the equation or rule relating the minutes, x, to the number of pages, y.
[tex]y=\frac{10}{3}x[/tex]
substitute x = 72
[tex]y=\frac{10}{3}\left(72\right)[/tex]
[tex]y=\frac{720}{3}[/tex]
[tex]y=240[/tex]
Therefore, the total pages are 240 when the minutes equal 72

What are the coordinates of point S?
(Negative three-fourths, one-half)
(Negative one-half, negative three-fourths)
(One-half, Negative three-fourths)
(Three-fourths, one-half)
Answer:
-3/4, 1/2
Step-by-step explanation:
Because the axis are split into 4ths, we can assume that each line is worth 1/4 in coordinates. S is located 3/4ths in the negative x direction and 2/4, or 1/2 in the positive y direction.
Computers store information in units called bits and bytes. There are 8 bits in one byte of data. Select the number of bits in one byte as a power with a base of 2.
Answer:
2^3
Step-by-step explanation:
Given that:
8 bits = 1 byte
To express 1 byte in bits in power notation with a base of 2 ;
1 byte = 8 bits
8bits = 2^x
8 bits = 2 * 2 * 2
8bits = 2^3
Hence,
1 byte = 2^3 bits
caitlin purchased a container of juice contains 200 calories. The label says that 40% of the calories are from carbohydrates. How many calories are from carbohydrates
Answer:
80 caloriesStep-by-step explanation:
Total calories = 200Calories from carbohydrates = 40% of totalCalculation:
40% of 200 = 40/100*200 = 40*2 = 80 caloriesGiven the function f(x) = 1/2x - 3, evaluate f(10).
Answer:
f(10)=2
Step-by-step explanation:
f(10) basically means you substitute 10 for x. SO you have f(10)= 1/2(10)-3. 1/2 times 10 equals 5 and 5 -3 is 2 so f(10)=2

Which one of these numbers is a perfect square? 21, 15, 6, 16, 27
Answer:
I think it is 16.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Perfect squares are numbers that can be written as the product of a different number and itself: k * k = k^2.
Looking at the numbers:
21: can be written as 3 * 7, but not in the form k^2
15: can be written as 3 * 5, but not in the form k^2
6: can be written as 2 * 3, but not in the form k^2
16: can be written as 4 * 4, which is in the form of k^2
27: can be written as 3 * 9, but not in the form k^2
Thus, the answer is 16.

What is the slope of the line?
Answer:
[tex] \boxed { \frac{1}{2} }[/tex]
Step-by-step explanation:
We can find the slope by using rise over run.
Given the coordinate points that are part of the graph.
[tex](1,4) \\ ( - 1,3)[/tex]
[tex]m = \frac{ 4 - 3}{1 - ( - 1)} \\ m = \frac{1}{1 + 1} \\ m = \frac{1}{2} [/tex]
Therefore the slope is 1/2.

Step-by-step explanation:
Hey there!
Step by step explanation:
2.7 is break apart to 200% and 70%. In decimal form, the 7 is 70. 1.0 is also known as 100. This means that 200 would be 200% since 1.00 is equal to 100 and 100 is equal or known as 100%. Now we can add 200% and 70% which would be 270%.
This means that 2.7 in a percent form is 270%.

What is the scale factor in the dilation?
Answer:
The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.
