Katie can bake 48 muffins in 90 minutes because 90 minutes is twice 45 minutes, and since she can bake 24 muffins in 45 minutes, double the time means she can bake double the amount of muffins.
Katie is baking muffins at a rate where she can bake 24 muffins in 45 minutes. To determine how many muffins she can bake in 90 minutes, we simply need to set up a proportion and solve for the unknown quantity.
Step-by-Step Solution:
Identify the rate: 24 muffins per 45 minutes.Understand that 90 minutes is twice 45 minutes, so we will have two periods of this duration.Since the rate of baking is consistent, we multiply the number of muffins (24) by the number of 45-minute periods within 90 minutes (which is 2).Calculate the total: 24 muffins per period x 2 periods = 48 muffins.Therefore, Katie can bake 48 muffins in 90 minutes because the duration is double the time it takes to bake the original 24 muffins, hence she can bake twice as many.

When an oil tank is 7/12 full, it contains 5 1/4gallons. How many gallons does it hold when full?
Final answer:
To determine the full capacity of the tank, the amount of oil it contains when it is 7/12 full (5 1/4 gallons) is divided by 7/12. After conversion and calculation, the full capacity is found to be 9 gallons.
Explanation:
The student's question asks, "When an oil tank is 7/12 full, it contains 5 1/4 gallons. How many gallons does it hold when full?" To find the full capacity of the tank, we divide the amount of oil when the tank is partially full by the fraction representing how full it is.
First, convert 5 1/4 gallons to an improper fraction: 5 1/4 = 21/4 gallons. Then divide this amount by 7/12 to find the full capacity.
Full capacity = (21/4) ÷ (7/12) = (21/4) × (12/7) = (21×12) / (4×7) = 252 / 28 = 9 gallons.
So, the full capacity of the oil tank is 9 gallons.

The length of a rectangle is 2 m greater than the width. The area is 168 m2 Find the length and the width
Answer:
Length = 14m
Width = 12m
Step-by-step explanation:
The length of a rectangle is 2m greater than the width.
The area of the rectangle = 168m²
Let's say the width is x meters.
The length will be (x + 2) meters.
Area of a rectangle = length × width
x(x + 2) = 168
x² + 2x - 168 = 0
Solving x by applying the quadratic formula we get;
x = 12 or -14
Since the width cannot be negative, we take 12 meters to be the dimensions of the width.
The length = 12 + 2 = 14 meters.
To find the length and width of the rectangle, we formulate an equation based on the known relationship between the dimensions and the given area. Solving the equation, we get the width as 12 m and length as 14 m.
Explanation:The question is about finding the length and width of a rectangle given the area and a relationship between the two dimensions. We can set up an equation based on the information given and the formula for the area of a rectangle. Namely, the area of a rectangle is equal to its length multiplied by its width (A = lw).
According to the problem, the length of the rectangle is 2 m more than the width. We can express this relationship as L = W + 2. We also know that the area of the rectangle is 168 m2, which results in the equation (W + 2)W = 168.
Solving this quadratic equation, we find that the width (W) is 12 m and the length (L) is 14 m. These are the dimensions of the rectangle.

Two students wrote the following numerical expressions.
Angeline: (7 + 15) × (38 + 15)
MeiLing: 15 × (7 + 38)
Are the students’ expressions equivalent to your answer in Problem 4? Explain your answer.
Answer:
The expression are not equivalent.
Step-by-step explanation:
For Angeline we have the next process:
[tex](7+15)\times(38+15)=22\times53=1166[/tex]
For MeiLing we have:
[tex]15\times(7+38)=15\times45=675[/tex]
Then we have that the students expressions are not equivalent.
The process to solver the expressions was solving first the parenthesis and after that solver the multiplication.
Angeline's and MeiLing's expressions are not equivalent; Angeline's result is 1166 whereas MeiLing's is 675, due to different placement of parentheses and the main operator used.
To determine if the expressions provided by Angeline and MeiLing are equivalent, we must first simplify both expressions using the order of operations.
Angeline's expression is: (7 + 15) × (38 + 15). First, we perform the additions inside the parentheses:
7 + 15 = 22
38 + 15 = 53
Now we multiply the sums:
22 × 53 = 1166
MeiLing's expression is: 15 × (7 + 38). Again, we first add the numbers inside the parentheses:
7 + 38 = 45
And then multiply by 15:
15 × 45 = 675
Angeline's result is 1166 and MeiLing's result is 675, so the two expressions are not equivalent. It's the placement of the parentheses and the use of the main operator that leads to different results. This illustrates the importance of following the proper mathematical rules and sequence of operations to get the correct answer.
Triangles A B C and A double-prime B double-prime C double-prime are shown. Triangle A double-prime B double-prime C double-prime is smaller and to the right of triangle A B C. Which transformations could have taken place to map △ABC to △A"B"C"? a reflection and a dilation a rotation and a dilation a translation and a dilation a reflection and a translation
PLEASE I NEED HELP ASAP
A smaller shape would be a dilation.
A move to the right would be a transition. (As long as the letters for the triangle are in the same orientation).
The answer should be:
A dilation a translation
There are various types of transformations that can be applied to a coordinate point. The new point could become compressed/enlarged, reflected, rotated, etc.
The transformations that transform [tex]\triangle ABC[/tex] to [tex]\triangle A"B"C"[/tex] are a translation and a dilation.
Given that:
[tex]\triangle A"B"C"[/tex] is smaller than [tex]\triangle ABC[/tex]
This means that sides of [tex]\triangle ABC[/tex] were dilated (i.e. compressed) to give the sides of [tex]\triangle A"B"C"[/tex]
Also:
[tex]\triangle A"B"C"[/tex] is at the right of [tex]\triangle ABC[/tex]
This means that [tex]\triangle ABC[/tex] was translated (i.e. shifted) to give [tex]\triangle A"B"C"[/tex]
Hence, the correct option is: a translation and a dilation.

Question
George invested $4400 in an account with annually compounded interest. After 5 years, he had $5790 in the account. What
was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign,
Answer:
The rate of interest was approx 5.64%.
Step-by-step explanation:
The compound interest formula is :
[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]
Here p = 4400
r = ?
n = 1
t = 5
A = 5790
Now putting the values in formula we get;
[tex]5790=4400(1+\frac{r}{1} )^{5}[/tex]
=> [tex]5790=4400(1+r )^{5}[/tex]
=> [tex]\frac{5790}{4400} =(1+r )^{5}[/tex]
=> [tex]1.316=(1+r )^{5}[/tex]
=> [tex]1+r=\sqrt[5]{1.316}[/tex]
r = 0.0564
In percentage it is [tex]0.0564\times100[/tex] = 5.64%
Hence, the rate of interest was approx 5.64%.

How can I Factor 9x2-1
Answer:
17 = 17^1
Step-by-step explanation:
Factor the following integer:
17
17 is not divisible by 2 since 17 is odd and 2 is even:
17 = 17 (17 is not divisible by 2)
The sum of the digits of 17 is 1 + 7 = 8, which is not divisible by 3. This means 17 is not divisible by 3:
17 = 17 (17 is not divisible by 2 or 3)
The last digit of 17 is not 5 or 0, which means 17 is not divisible by 5:
17 = 17 (17 is not divisible by 2, 3 or 5)
Divide 7 into 17:
| | 2 | (quotient)
7 | 1 | 7 |
- | 1 | 4 |
| | 3 | (remainder)
17 is not divisible by 7:
17 = 17 (17 is not divisible by 2, 3, 5 or 7)
The alternating sum of the digits of 17 is 1 - 7 = -6, which is not divisible by 11. This means 17 is not divisible by 11:
17 = 17 (17 is not divisible by 2, 3, 5, 7 or 11)
Divide 13 into 17:
| | | 1 | (quotient)
1 | 3 | 1 | 7 |
| - | 1 | 3 |
| | | 4 | (remainder)
17 is not divisible by 13:
17 = 17 (17 is not divisible by 2, 3, 5, 7, 11 or 13)
No primes less than 17 divide into it. Therefore 17 is prime:
17 = 17
Since 17 is prime it has an exponent of 1:
Answer: 17 = 17^1

If angle jnp =2x+3 and angle knl =3x-17 and angle knj =3x+34 find the measure of each angle
Answer:
m∠JNP=43°
m∠KNJ=94°
m∠KNL=43°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠JNP+m∠KNJ+m∠KNL=180° ----> by definition of supplementary angles
we have
m∠JNP=(2x+3)°
m∠KNJ=(3x+34)°
m∠KNL=(3x-17)°
substitute the values
(2x+3)°+(3x+34)°+(3x-17)°=180°
Combine like terms in the left side
(8x+20)=180
Subtract 20 both sides
8x=180-20
8x=160
x=20
Find the measure of m∠JNP
m∠JNP=(2x+3)°
substitute the value of x
m∠JNP=(2(20)+3)=43°
Find the measure of m∠KNJ
m∠KNJ=(3x+34)°
substitute the value of x
m∠KNJ=(3(20)+34)=94°
Find the measure of m∠KNL
m∠KNL=(3x-17)°
substitute the value of x
m∠KNL=(3(20)-17)=43°
