A book has 240 pages and each day 10 pages are
read. The number of pages left, p, is given as a
function of d, the time in days, where
p = 240 – 10d . Graph the equation, then use its
x-intercept to determine when the book will be
finished?
Answers
Answer:
24 days is the answer
Step-by-step explanation:
If the book is 240 pages and each day 10 pages are read you could easily divide 240 by 10 and get 24. However, you need to use the formulas for your answer I suppose. So, to get the x-intercept this is what you do. You have to use the slope-intercept form y = mx+b where m=-10 and b = 240 so you end up with y = -10x+240
So now you solve for x-intercept
0 = -10d+240
subtract 240 from both sides so 0 = -10d + 240
-240 -240
you are left with -240 = -10d. Now simplify and divide each term by -10 -240/-10 = 24 and -10d/-10 = d
you are left with d = 24 or 24 = d
You graph the equation by placing a point at 240 on the y axis and 24 on your X-axis.

What is the vertex of this parabola?
y-5 = x^2?
Answers
====================================================
Work Shown:
y-5 = x^2
y = x^2 + 5 ... add 5 to both sides
y = 1x^2 + 5
y = 1(x-0)^2 + 5 ... x replaced with (x-0)
The equation is now in the form y = a(x-h)^2 + k
We have a = 1, h = 0, k = 5.
The vertex is (h,k) = (0,5)
The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.

Take the square root of both sides:

A student did an experiment to determine the number of letters recognized on an eye chart to see if it was affected by distance. What is the independent and dependent variable in this experiment?
Answers
Answer:
Independent variable: distance
Dependent variable: number of letters recognized on an eye chart
Step-by-step explanation:
Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.
Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.
Since the hypothesis is that the distance affects the number of letters recognized,
the distance causes a change in the number of letters recognized not the other way around.
Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

T = L(8 + RS)
Solve for R
Answers
Answer:
Step-by-step explanation:
T=L(8+RS)
T=L8+LRS
T-L8=LRS
R=T-L8/LS
The required solution to the given equation is R = (T - 8L)/LS.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
T = L(8 + RS)
Apply the distributive property of multiplication,
T = L × 8 + L × RS
T = 8L + LRS
Rearrange the terms in the above equation,
T - 8L = LRS
Divided by LS into both sides, and we get
R = (T - 8L)/LS
Thus, the required solution to the given equation is R = (T - 8L)/LS.

Barry made the model to show multiplying a fraction by a fraction. Which multiplication sentence does the model show? A grid with 3 rows of 6 columns showing 18 squares total. The 12 squares in the top two rows are shaded yellow, the 15 squares in the first 5 columns are shaded blue. The shading overaps to make green in 10 squares. 13×23=29 26×56=518 13×26=19 23×56=59
Answers
Given:
Number of rows = 3
Number of columns = 6
Number of square boxes = 18
yellow square boxes in the top two rows = 12
Blue square boxes in the first 5 columns = 15
Number of green boxes (shading overlaps) = 10
To find:
The model to show multiplying a fraction by a fraction.
Solution:
2 rows out of 3 are shaded yellow.
Fraction for yellow = [tex]\dfrac{2}{3}[/tex]
5 columns out of 6 are shaded blue.
Faction for blue = [tex]\dfrac{5}{6}[/tex]
10 out of 18 squares are green.
Faction for green = [tex]\dfrac{10}{18}=\dfrac{5}{9}[/tex]
Now,
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}[/tex]
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}[/tex]
Therefore, the correct option is D.
The correct option is D.
The calculation is as follows:
2 rows out of 3 are shaded yellow.
Fraction should be [tex]2\div 3[/tex]
Now
5 columns out of 6 are shaded blue.
Fraction should be [tex]5 \div 6[/tex]
And,
10 out of 18 squares are green.
Fraction should be [tex]10 \div 18 = 5\div 9[/tex]
Now
[tex]\frac{2}{3} \times \frac{5}{6} = \frac{10}{18}\\\\ \frac{2}{3} \times \frac{5}{6} = \frac{5}{9}[/tex]
