The number of steps Erin could paint if he has 5/4 parts of paint, and she needs 2/8 of paint for each stair step, is 5.
What is division?It is a basic operation of mathematics in which you divide a number into smaller parts.
Given:
Erin has 5/4 quarts of paint,
2/8 of paint for each stair-step,
Calculate the number of steps painted as shown below,
Number of steps = total paint / paint required for each step
Number of steps = 5/4 / 2/8
Number of steps =

Answer:
This is often called scaling in math, used in ratios, fraction, percent's etc.
Step-by-step explanation:
Answer:
You can use similar processes when converting from smaller to larger units. When converting a larger unit to a smaller one, you multiply; when you convert a smaller unit to a larger one, you divide. Here is an example..

Find the unit rate for each, then compare. Which is faster?
8 laps in 70 seconds
12 laps in 98 seconds.
Answer:
8 laps in 70 seconds is faster.
Step-by-step explanation:
If we divide 70/8 and 98/12 we get the following:
70/8= 8.75
98/12=8.16
8.75>8.16
The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds

the scatterplot shows the number of hours that 12 people spent learning to type on a keyboard and each persons average typing speed. Based on the scatterplot, what is the best prediction of a persons average typing speed in words per min. if the person has spent 70 hours learning to type?
Answer:
85 wpm
Step-by-step explanation:
From the scatter plot, we can see the following;
At 20 hours, average typing speed = 34 wpm
At 30 hours, the average typing speed = 40 wpm
At 40 hours, the average typing speed = 51 wpm
At 50 hours, the average typing speed = 65 wpm
Average differences = ((40 - 34) + (51 - 40) + (65 - 51))/3 = 10.3
Approximating to a whole number = 10
Now, we can approximate that at 60 hours, average typing speed = 65 + 10 = 75 wpm
At 70 hours, the average typing speed = 75 + 10 = 85 wpm
Answer:
85 wpm

The sixth grade art students are making a mosaic using tiles in the shape of triangles.Each tile Hans leg measures of 7cm and 4cm. If there are 84 tiles in the mosaic,what I sent the area of the mosaic
Answer:
1,176 square centimeters
Step-by-step explanation:
The computation of the area of the mosaic is shown below:
As we know that
The Area of the triangle is
= 1 ÷ 2 × base × height
= 1 ÷ 2 × 7 × 4
= 14
Now 1 tile would be 14 square centimeters
And, there are 84 tiles in the mosaic
So, the total area is
= 84 × 14
= 1,176 square centimeters

What is the line of symmetry for the parabola whose equation is y = x2 + 10x + 25?
A-x = -5
B-x = 5
C-x = -10
Answer:
x = -5
Step-by-step explanation:
Please write this as y = x^2 + 10x + 25. Here the coefficients are {1, 10, 25}.
The equation of the axis of symmetry is x = -b/[2a], which here is
x = -10 / [2*1] = -5

Sarah is self-publishing her 300-page novel and wants to estimate the printing costs.
Answer the questions to estimate the cost of printing a 300-page paperback book.
1. What is the y-intercept for the trend line? What is the real-world meaning of this point?
2. One point on the trend line is (200, 6). Using this point and the y-intercept, find the slope of the trend line. Show your work.
3. What is the real-world meaning.of the slope?
4. Use the slope and y-intercept to write an equation for the trend line in slope-intercept form.
5. Use your equation to estimate the cost of printing Sarah's 300-page book.
1. Y-intercept b=5
That means it has a 5.00 starting fee.
2. Using the formula (Y2-Y1)/(X2-X1) we will find the slope between the two points.
Point one (X1 and Y1) will be the Y-intercept.
X1,Y1 = (0, 5.00)
Point 2 (X2 and Y2) will be the point on the trend line.
X2, Y2 = (200, 6.00)
Plug in:
(6.00 - 5.00)/(200 - 0) = 00.5 or 1/200.
3. When printing 200 pages each page will cost $.005.
4. .005x+5
5. .005x+5
.005(300)+5=6.5
