Answer:
Peter walks at a rate of 13/4 miles per hour.
Step-by-step explanation:
Peter walks at a rate of 13/4 miles per hour because every hour, represented by x, he walks 3.25 hours or 13/4. y is the total miles he walked so if he walks two hours the y would equal 6.5 or 26/4 and the x would equal 2.

Georgette created a factor tree and wrote the prime factorization of 72 shown here. A factor tree of 72. 72 branches to 8 and 9. 8 branches to 2 and 4. 4 branches to 2 and 2. 72 = 23 × 9 What is Georgette’s error? A. Georgette should have started the factor tree with 2 × 36. B. Georgette did not complete the factorization; 9 is a composite number. C. Georgette should have expressed 4 as 4 x 1, not 2 x 2. D. Georgette should have expressed 8 as 4 × 4, not 2 × 4.
Answers
Answer:
Georgette did not complete the factorization; 9 is a composite number.
Step-by-step explanation:
9 can be broken down to 3x3
So it the prime factorization of 72 should be 2x2x2x3x3
Georgette’s error is Georgette should have expressed 8 as 4 × 4, not 2 × 4.
The correct option is D.
The correct prime factorization of 72 is 2³ × 3², which means it can be expressed as the product of prime numbers raised to their respective exponents.
Analyzing the factor tree provided by Georgette, we can see that she made an error when branching from 72 to 8 and 9.
The prime factorization of 8 should be 2³, not 2 × 4, and the prime factorization of 9 should be 3², not 2 × 2.
Therefore, Georgette's error is that she have expressed 8 as 2³ × 1 or 4 × 2, not as 2 × 4.
The correct factor tree for 72 would be:
72
/ \
2 36
/ \
2 18
/ \
2 9
/ \
3 3
So, the prime factorization of 72 is 2³ × 3².

At a carnival game, you randomly throw two darts at the board and break two balloons. What is the probability that both the balloons you break are purple? Write your answer as a fraction or percent rounded to the nearest tenth. there are 15
Answers
Details are missing;
A board of 15 balloons. 4 are purple, 3 red, 4 blue, 2 yellow and 2 green
Answer:
the probability that both the balloons you break are purple = 2/35
Step-by-step explanation:
Since there are 15 balloons and 4 are purple. It means that probability of the first balloon being purple is;
4/15
Now, if the first balloon is purple, it means we have 3 purple left out of the remaining 14. Thus probability of the second being purple = 3/14
Thus;
the probability that both the balloons you break are purple = 4/15 × 3/14 = 2/35

Write the set of real numbers between 110 and 220 in interval notation.
Answers
Answer:
[tex]110\geq x \leq 220[/tex]
Step-by-step explanation:
Given
Minimum: 110
Maximum = 220
Required
Write as interval notation
Let the real numbers be represented with x
We start by setting x greater than or equal to the minimum:
[tex]x \geq 110[/tex]
Then, we set x less than or equal to the maximum:
[tex]x \leq 220[/tex]
Write out both inequalities
[tex]x \geq 110[/tex] and [tex]x \leq 220[/tex]
This can be rewritten as:
[tex]110 \geq x[/tex] and [tex]x \leq 220[/tex]
Both inequalities can be merged to give:

Point N is on line segment MO. Given MO = 3x - 10, NO = x, and M N = 8,
determine the numerical length of MO.
Answers
Answer:
MO = 17
Step-by-step explanation:
First, you need to define what if the unknown x.
segment MN and NO are equal to MO.
thus, your equation for the combination is x +8
Now set the values equal to each other
x + 8 = 3x - 10 (subtract x from both sides)
8 = 2x - 10 ( get your x value alone, add 10 to both sides)
18 = 2x (simplfy)
x = 9
Now plug x value into MO
3 (9) - 10 = 17
Check with opposing equation:
9 + 8 = 17 √

Answer:
B
Step-by-step explanation:
Given
[tex]\frac{1}{(t-2)^2}[/tex] = 6 + [tex]\frac{1}{(t-2)}[/tex] ( multiply through by (t - 2)²
1 = 6(t - 2)² + t - 2 ← distribute parenthesis and simplify
1 = 6(t² - 4t + 4) + t - 2
1 = 6t² - 24t + 24 + t - 2
1 = 6t² - 23t + 22 ( subtract 1 from both sides )
6t² - 23t + 21 = 0 ← in standard form
(2t - 3)(3t - 7) = 0 → in factored form
Equate each factor to zero and solve for t
2t - 3 = 0 ⇒ 2t = 3 ⇒ t = [tex]\frac{3}{2}[/tex] ← p
3t - 7 = 0 ⇒ 3t = 7 ⇒ t = [tex]\frac{7}{3}[/tex] ← q
Thus
p × q = [tex]\frac{3}{2}[/tex] × [tex]\frac{7}{3}[/tex] = [tex]\frac{21}{6}[/tex] = [tex]\frac{7}{2}[/tex] → B

Answer:
p= (9.1 x 10^-31)(2.18 x 10^6) p = 1.9 x 10^-22kg*m/s
Step-by-step explanation:
for i said so
The momentum of electron is [tex]1.9\times 10^{26}[/tex] kg m per second.
Given, mass of electron is [tex]9.1\times 10^{-31}[/tex] kg.
And its velocity is [tex]2.18 \times 10^6[/tex] m per s.
We have to calculate its momentum.
We know that momentum is numerically equal to the product of mass and velocity of a particle and denoted by p.
So, [tex]p=mv[/tex]
[tex]p= 9.1\times10^{-31}\times2.18\times10^{6}[/tex]
[tex]p=19.838\times10^{25}[/tex]
[tex]p=1.9\times10^{26}[/tex]
Hence the momentum of electron is [tex]1.9\times 10^{26}[/tex] kg m per second.

A bike shop rents bikes for $4.50 per hour, plus a $7.50 insurance charge. For how many hours can Peter rent a bike if he has $30?
Answers
Answer:
With $30, Peter can afford 5 hours
Step-by-step explanation:
Given
Insurance Charge = $7.5
Charges = $4.5 per hour
Required
Determine the number of hours $30 can afford
First, we need to determine the equation.
Total Charges = Charges per hour + Insurance Charge
Substitute values for Charges per hour and Insurance Charge
Total Charges = 4.5 per hour + 7.5
Let the number of hours be n;
So,
Total Charges = 4.5n + 7.5
To calculate Peter's; substitute 30 for total charges
[tex]30 = 4.5n + 7.5[/tex]
Subtract 7.5 from both sides
[tex]4.5n = 30 - 7.5[/tex]
[tex]4.5n = 22.5[/tex]
Divide both sides by 4.5
[tex]n = \frac{22.5}{4.5}[/tex]
[tex]n = 5[/tex]
Hence;
With $30, Peter can afford 5 hours

Step-by-step explanation:
The translation path of Point A (3, -8) to A'(-4,-5) exists 3 units down and 7 units to the left.
What is meant by translation?A translation in mathematics does not turn, but rather moves a shape left, right, up, or down. Congruent translations are those in which the translated shapes (or the image) seem to be the same size as the source ones. Just one or more directions have they shifted.
Each point in a figure is moved by the same amount and in the same direction during a translation, a type of transformation.
With a sort of transformation called translation, every point in a figure is moved the same distance in the same direction.
