Answer:
Bot #11
Step-by-step explanation:
If you picked bot 12 in 5 second it produces 21 clicks which means if you add another 5 second it will be 10 second with 42 clicks. But, if you pick the bot with 17 clicks per 4 second, 8 seconds it will already be 34 clicks and 10 seconds half of 17 is 8/5 which in 10 seconds it produces 42.5 which shows the first bot produces more.

3x+2=5x-10
-3x -3x
2=2x-10
+10 +10
12=2x

The value of x is 6 and the value of QR will be 8 units.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that the value of x and QR if Q is between P and R.
PQ=2x
QR=x + 2
PR= 5x -10
The value of x will be calculated as below:-
2x+x+2=5x-10
3x+2=5x-10
2=2x-10
12=2x
x = 12 / 2
x =6
The value of QR will be calculated as below:-
QR=x+2
6+2=8
Therefore, the value of x is 6 and the value of QR will be 8 units.

Can i have more details explanation about the ways to find the answers?
Answer:
I can't answer the B question, but I can answer the A question. First, you need to add 1/3, 1/4, and 5/8 by converting them into having the same denominators (24 is the best) and then subtracting them by 24/24 or the number of your choosing. That's how you find out how much he saves.

A certain forest covers an area of 4900 km². Suppose that each year this area decreases by 7%. What will the area be after 8 years?
Use the calculator provided and round your answer to the nearest square kilometer.
Answer:
area after 8 years is 2156km²
Step-by-step explanation:
Area of forest=4900 km²
decrease in area in 1 year=4900km² × 7%
decrease in area in 1 year= 343km²
decrease area in 8 years=343km² × 8
=2744km²
Remaining area= (4900-2744)km²
=2156km²

is x + 1 a factor of [tex]x^{4} +2x^{3} +2x^{2} -2x-3[/tex]?
Answer:
Yes.
Step-by-step explanation:
We want to determine if (x + 1) is a factor of the polynomial:
[tex]x^4 + 2x^3 + 2x^2 - 2x -3[/tex]
According to the Factor Theorem, if a binomial in the form (x - a) is a factor of a polynomial P(x), then P(a) must equal zero.
Our binomial factor is (x + 1) or (x - (-1)). Hence, a = -1.
Let our polynomial be P(x). Find P(-1):
[tex]\displaystyle\begin{aligned} P(-1) &= (-1)^4 + 2(-1)^3 +2(-1)^2 -2(-1) -3 \\&=0\end{aligned}[/tex]
Therefore, since the resulting value is indeed zero, (x + 1) is indeed a factor of the given polynomial.
In conclusion: yes.
The scatterplot to the left shows the cost, C, in thousands of dollars, and living space, z, in square feet (ft) for several houses in a certain neighborhood. According to the data, which of the following best approximates the cost for an additional square foot of living space for homes in this neighborhood?
The best approximation of the cost for an additional square foot of living space for homes in this neighborhood is a decrease of $0.125 thousand, or $125, for every one additional square foot of living space.
Since we are looking for an approximation of the cost for an additional square foot of living space, we need to find the slope of the line of best fit for the given scatterplot. The slope of the line represents the change in the cost of the house for every one unit increase in the living space, which in this case is one square foot.
From the scatterplot, we can see that as the living space increases, the cost of the house also increases, indicating a positive linear relationship. We can also see that there is a line of best fit that closely approximates this relationship.
To find the slope of the line of best fit, we can choose any two points on the line and calculate the change in the y-coordinate (the cost) divided by the change in the x-coordinate (the living space). One way to do this is to choose the two points where the line intersects the y-axis and the x-axis. From the scatterplot, we can estimate these points to be approximately (0, 200) and (1600, 0), respectively.
Using these two points, the slope of the line of best fit is:
slope = (change in y) / (change in x)
slope = (200 - 0) / (0 - 1600)
slope = -0.125
Therefore, the best approximation of the cost for an additional square foot of living space for homes in this neighborhood is a decrease of $0.125 thousand, or $125, for every one additional square foot of living space.

Convert 99000 milligrams into pounds. Round your answer to the nearest hundredth.
Answer:

Step-by-step explanation:
A 10 1/2-inch candle burns down in 7 hours. If b represents how much of the candle, in inches, has burned away at any time given in hours, t, write a proportional equation for b in terms of t that matches the context.
The proportional formula for b is 3/2 in terms of t.
What is proportional equation?The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k. If an equation in another form can be rewritten as in the example above, then the relationship is proportional.Assume that b = kt is the equation.In light of the statement 10 1/2 = k.7So, k = 10 1/2 /7 =21/2 /7 => 3/2Therefore, the equation is b = 3/2t, where t is the proportionality factor.y = k x, where is the proportionality constant, is the equation that depicts a proportional relationship, or a line. Find k and create the equation by using k = y x from a table or graph. Tables, graphs, and equations can all be used to represent proportional relationships.To learn more about proportional equation refer to:

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?
A. p = 250(1.21)
B. p = 250(1.79)
C. p= 250(0.79)
D. p=250(0.21)
Answer: Choice C. p = 250(0.79)^t
Work Shown:
p = a*b^t
p = a*(1+r)^t
p = 250*(1+(-0.21))^t
p = 250(0.79)^t
Note that r = -0.21 is negative to indicate we have exponential decay.

write each fraction number as a decimal 33/40
Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825

If a^2+b^2=13 and ab =6 find the value of
(i)(2a+2b)
(ii)(2a-2b)
Answer:
I)
[tex]2a + 2b = -10\text{ or } 2a + 2b = 10[/tex]
II)
[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaytstyle a^2 + b^2 = 13 \text{ and } ab= 6[/tex]
I)
Recall the perfect square trinomial pattern:
[tex]\displaystyle (a+b)^2 = a^2 + 2ab + b^2[/tex]
Rewrite:
[tex]\displaystyle (a+b)^2 = (a^2 + b^2) + (2ab)[/tex]
Substitute:
[tex]\displaystyle (a+b)^2 = (13) + (12)[/tex]
Evaluate:
[tex]\displaystyle (a + b)^2 = 25[/tex]
Take the square root of both sides:
[tex]\displaystyle a + b = \pm\sqrt{25} = \pm5[/tex]
Hence:
[tex]\displaystyle 2a + 2b = \pm 10[/tex]
Therefore:
[tex]\displaystyle 2a + 2b = -10 \text{ or } 2a + 2b = 10[/tex]
II)
Likewise:
[tex]\displaystyle (a-b)^2 = a^2 - 2ab + b^2[/tex]
Substitute:
[tex]\displaystyle (a-b)^2 = (13) -(12)[/tex]
Solve:
[tex]\displaystyle \begin{aligned} (a-b)^2 &= 1 \\ a-b &= \pm \sqrt{1} \\ a-b &= \pm 1\\ 2a - 2b &= \pm 2\end{aligned}[/tex]
In conclusion:
[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]
