Rod has to read a book which has p pages. He plans to read r pages each day for d days.
Write an equation for the number of pages left, b, in the book, after d days.
Answers
Answer:
Look at the attachment
The equation is an illustration of a linear function.
The equation for the number of pages left in the book is \(b =p- rd\)
The total number of pages is:
\(Total = p\)
The daily rate is:
\(Rate = r\)
So, the number of pages read in d days is:
\(Pages = Rate \times Days\)
This gives
\(Pages = r \times d\)
Multiply
\(Pages = rd\)
The number of pages left (b) is then calculated as:
\(b =Total - Pages\)
So, we have:
\(b =p- rd\)
Hence, the equation for the number of pages left in the book is \(b =p- rd\)

Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Step-by-step explanation:
you are completely right please follow your heart <3
You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

Step-by-step explanation: This entire paper is just about combining like terms.
I won't go too in depth about it since it's self-explanatory, but I'll explain it just a bit. Like terms are two terms that have the same variable. For example, 19 and 24 are like terms since they are both numbers. 15x and 18x are like terms since they are both the same variables. 2y and 5y are like terms since they are both the same variables. However, 3x and 4y are NOT like terms, they do not have the same variable.
Also, variables that have different exponential powers are also not like terms. For example, 5x^2 and 7x are not like terms as one is squares and one is to the 1st power. Similarly, 3x^3 is not the same variable as 2x^4.
When you have 5x and -2x, you subtract 5x and 2x. Thus, the combination would be 3x. When you have -4x - 2x, you would get -6x, and if you have -4x + 2x, you would get -2x.
What you were supposed to do is simplify the equations by combining like terms, and then crossing off the letters that correspond to what you have left in the expression. The remaining letters should spell out a joke.

Answers
Answer:
(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

d. 8/12
Answers
Answer: D. 8/12
Step-by-step explanation:
8/12 is the equivalent fraction to 2/3 which we can see when the fraction is put into it's simplest form.
See here: In the fraction 8/12, there is an 8 as the numerator (top number) and a 12 as the denominator (bottom number). When we look at these, it is crucial to find the GCF (greatest common factor) so it can be put into simplest form. In this case, 8's factors are (1x8) and (2x4). 12's factors are (1x12), (2x6), and (3x4). Looking at these factors for both numbers, we can see that they both have a 2 and a 4. However, because the 4 is the greater number, it is our GCF. Now divide the numerator and the denominator by 4 to get 2/3
