Answer:
Step-by-step explanation:
squirrel speed (r) x seconds (3) has to be more than 34 feet
3r is greater than 34
r is greater than 11.3
34 / 3 = 11.333
11.3 (squirrels speed) x 3 (seconds) = 33.9 feet
the squirrel can run faster than 11.3
Answer:
A). Option A
B). Option B
C). Option B
Step-by-step explanation:
A). A squirrel runs across a road in 3 seconds.
Width of the road is more than 34 feet.
We have to calculate the squirrel speed.
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
= [tex]\frac{34}{3}[/tex]
Since distance is more that 34 so the speed will be more than [tex]\frac{34}{3}[/tex]
This is because Speed ∝ Distance.
Let r is the speed of squirrel.
r > [tex]\frac{34}{3}[/tex]
3r > 34
Option A is the correct option.
B). Inequality is 3r > 34
r > [tex]\frac{34}{3}[/tex]
r > 11.3
Option B is the answer.
C). The squirrel can run at faster than 11.3 feet per second.
Option B.

Answer:
A. [tex]C=K-273[/tex]
Step-by-step explanation:
You are given the formula
[tex]K=C+273[/tex]
You have to find C in terms of K. Subtract 273 from both sides of this equation:
[tex]K-273=C+273-273\\ \\K-273=C\\ \\C=K-273[/tex]
ANSWER
C=K-273
EXPLANATION
The given formula is: K=C+273
We need to solve this formula for the variable, C.
This means that we need to isolate the variable C on one side of the equation, leaving any other terms on the other side of the equation.
We subtract 273 from both sides of the equation to obtain,
K-273=C
This is the same as
C=C-273

Can you help me with this word problem?
Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1

Answer:
a) third; from left most graph
b) fourth; right most graph
Step-by-step explanation:
Part a)
The graph is between the speed and time.
Nicole begin jogging faster and faster i.e. speed is increasing w.r.t time thus we have linear line in beginning.
Then she hits a comfortable speed and stayed at it i.e. speed remained constant for that time. Thus we have a straight line.
After that she gradually slows down,i.e speed is decreasing w.r.t time. Thus we have decreasing linear line.
So the graph shape is linear line with increasing slope-a constant straight line-linear line with decreasing slope
which is the third; from left most graph in option
Part b)
The graph is between Distance to campus and time.
As Dale is hiking towards campus, distance should decrease w.r.t time.
In beginning, he is hiking at constant speed towards campus thus the distance towards the campus is decreasing w.r.t time. We get a decreasing linear line.
*Note: here constant speed is not important, instead hiking towards i.e. the direction is important because of the campus distance covered
Then he sees a snake and turn and runs the other way. Thus now the distance towards the campus is increasing. And we get increasing linear line.
*Note running other way is important because of the campus distance covered
After that, he sits for a while i.e he stops and so the distance towards campus also become constant w.r.t time. we get a straight line on the graph.
So the graph shape is linear line with decreasing slope-linear line with increasing slope-a constant straight line
which is the right-most graph in option !
3. Consider the following box plot.
(a) Find the interquartile range.
(b) What percent of values is included in the interquartile range?
Answer:
A) 2.5
B) 50% of the values.
Step-by-step explanation:
A)
The range of data starts at 2.0 and ends at 4.5 (i know it's a bit hard to tell lol), by subtracting 2.0 from 4.5 you get the interquartile range, 2.5.
B)
25% of the values are mentioned in the box plot before the median, and 25% of the values are mentioned after the median in the box plot. This together gives you a sum of 50% of the values. Another way to do it is that outside of the interquartile range is 50% of the values.

If m is a prime number, list all factors of m×m.
For a prime number m, the only factors of m x m would be 1, m, and [tex]m^2[/tex]
If m is a prime number, the factors of m would be 1 and m itself since prime numbers have no divisors other than 1 and themselves. When you calculate m x m which is [tex]m^2[/tex], the factors list expands slightly but remains quite simple due to the nature of prime numbers.
1 (1 can divide any number)m (since m is a prime and can divide its square)[tex]m^2[/tex] (the square of the prime number is a factor of itself)Those would be all the factors of [tex]m^2[/tex] when m is a prime number.
THIS IS 61 POINTS. Find the first three terms of the sequence described by the following recursive formula: an = 3an – 1 + 2 where a4 = 20
a1=
a2=
a3=
Answer:
see explanation
Step-by-step explanation:
Given the recursive formula
[tex]a_{n}[/tex] = 3[tex]a_{n-1}[/tex] + 2 and a₄ = 20
Then working in reverse
3a₃ + 2 = 20 ( subtract 2 from both sides )
3a₃ = 18 ( divide both sides by 3 )
a₃ = 6
3a₂ + 2 = 6 ( subtract 2 from both sides )
3a₂ = 4 ( divide both sides by 3 )
a₂ = [tex]\frac{4}{3}[/tex]
3a₁ + 2 = [tex]\frac{4}{3}[/tex] ( subtract 2 from both sides )
3a₁ = - [tex]\frac{2}{3}[/tex] ( divide both sides by 3 )
a₁ = - [tex]\frac{2}{9}[/tex]
Hence
a₁ = - [tex]\frac{2}{9}[/tex]
a₂ = [tex]\frac{4}{3}[/tex]
a₃ = 6
a1 = (-2/9)
a2 = 4/3
a3 = 6

1/3 b = 5/4 . Which of the following equals b in this equation? A. 2 2/5 B. 1 1/8 C. 2/5 D. 1/4
Answer:
Step-by-step explanation:
Multiplying both sides of this equation by 3/1 will isolate b:
(3/1)(1/3)b = (3/1)(5/4) = 15/4 or 3 3/4.
Answer:
15/4
Step-by-step explanation:
Ok so the equation we have is:
[tex]\frac{1}{3} b = \frac{5}{4}[/tex]
Now we can multiply both sides by 3
[tex]1b = 15/4[/tex]
[tex]\frac{15}{4}[/tex]
Which of the following is a correct interpretation of the expression 2 + 7?
Choose 1 answer:
(A)
The number that is 2 to the left of - 7 on the number line
i on the number line
(c)
The number that is T to the left of 2 on the number line
(D). The number that is 7 to the right of 2 on the number line
Answer:
(D). The number that is 7 to the right of 2 on the number line
Step-by-step explanation:
It could also be the number that is 2 to the right of 7 on the number line. When numbers are added, the distances of each to the origin are laid end-to-end from the origin to the right on the number line.
2+7 can mean that the distance 2 is added to the distance 7, or vice versa. (The commutative property of addition says order does not matter.)
Answer: D is right, not lying

Part B: Solve for x using an appropriate method. SHOW THE STEPS OF YOUR WORK.
Answer: x=-16/11
6+11x+10=0
We add all the numbers together, and all the variables
11x+16=0
We move all terms containing x to the left, all other terms to the right
11x=-16
x=-16/11
Answer:
Vertex:
Roots: [tex]x=\frac{5}{3}[/tex] or [tex]x=2[/tex]
Step-by-step explanation:
The given quadratic equation is:
Let [tex]f(x)=3x^2-11x+10[/tex]
We obtain the vertex form by completing the square;
[tex]f(x)=3(x^2-\frac{11}{3}x)+10[/tex]
Add and subtract the square of half the coefficient of x.
[tex]f(x)=3(x^2-\frac{11}{3}x+(-\frac{11}{6})^2+10-3(-\frac{11}{6})^2)[/tex]
This simplifies to
[tex]f(x)=3(x-\frac{11}{6})^2-\frac{1}{12}[/tex]
Hence the vertex is [tex](\frac{11}{6},-\frac{1}{12})[/tex]
We now solve to obtain:
[tex]3(x-\frac{11}{6})^2-\frac{1}{12}=0[/tex]
[tex]3(x-\frac{11}{6})^2=\frac{1}{12})[/tex]
[tex](x-\frac{11}{6})^2=\frac{1}{36})[/tex]
[tex](x-\frac{11}{6})=\pm \sqrt{\frac{1}{36}}[/tex]
[tex]x=\frac{11}{6}\pm \frac{1}{6}[/tex]
[tex]x=\frac{5}{3}[/tex] or [tex]x=2[/tex]
identify the amplitude of the graph
ANSWER
The amplitude is 1.6
EXPLANATION
The amplitude is half of the highest value minus the least values.
The highest value on the graph also occurs at 0, which is 5.20
The least value is 2
The amplitude is
[tex] = \frac{5.20-2}{2} = 1.6[/tex]
Therefore the amplitude is 1.6
The number 15. 24 is an example of a repeating decimal.
true. false.
No, the number 15.24 is not a repeating decimal.
Explanation:No, the number 15.24 is not an example of a repeating decimal.
A repeating decimal is a number whose decimal representation goes on forever and repeats a block of one or more digits. For example, the number 0.3333... is a repeating decimal because the digit 3 repeats infinitely.
In the case of 15.24, the decimal representation terminates after two decimal places.
This is because it has a fixed and finite decimal representation. The digits "15" represent the whole number part, and the "24" represents the fractional part. Since there is no repeating pattern of digits after the decimal point, 15.24 is classified as a terminating decimal, not a repeating one.
Therefore, it is not a repeating decimal.

What should be done to x^2+ 15x in order to create a perfect square?
Answer:
Add 225/4 to x^2 + 15x.
Step-by-step explanation:
Take the coefficient of the middle term, 15.
Now divide it by 2, 15/2.
Square that, 225/4.
Add 225/4 to x^2 + 15x.
To create a perfect square, add 225/4 in the quadratic function x²+ 15x.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a quadratic function:
= x²+ 15x
To create a perfect square, add and subtract by 225/4
= x²+ 15x + 225/4 - 225/4
= x²+ 15x + 15²/2² - 225/4
= (x + 15/2)² - 225/4
Thus, to create a perfect square, add 225/4 in the quadratic function x²+ 15x.
