Selena made pancakes for an all-day breakfast fundraising event. She made 132 pancakes in 2 hours. Selena needs to make 264 more pancakes. If she continues at the same rate, how many hours will it take for Selena to make 264 more pancakes?
Selena needs 4 more hours to prepare 264 more pancakes.
What is unitary method?Unitary method is a process of finding the value of a single unit, and use this value to find the value of the required number of units.
Given is Selena made pancakes for an all-day breakfast fundraising event. She made 132 pancakes in 2 hours. Selena needs to make 264 more pancakes.
We have -
The rate at which Selena is making pancakes = 132 pancakes in 2 hours.
Number of pancakes left to be made = 264
Now, in 2 hrs she makes 132 pancakes
Then, in 1 hr she will make (132/2) or 66 pancakes.
Now, she makes 66 pancakes in 1 hour.
So, she will make 1 pancake in (1/66) hours
Therefore, she will make 264 pancakes in (264/66) or 4 hours.
Therefore, she will need 4 more hours to prepare 264 more pancakes.

Devon is saving to buy a telescope. If he saves 7$ a week for 14 weeks which equation can be used to fund the total cost
Answer: Multiply 7 and 14
Step-by-step explanation: to find the answer you multiply 7 and 14 you get 98$ which is the total cost pls consider making me brainliest if im correct i really hope i am :)) make sure to tell me if im wrong
Answer:
Step-by-step explanation:
Step 1: Assume your variables
We can see that the money is being saved on a weekly basis.
So, let's assume the number of weeks for which the money is being saved to be the variable: [tex]x[/tex]
And let's consider the total cost after [tex]x[/tex] weeks to be: [tex]y[/tex]
Step 2: Manipulate the variables according to the information given
$7 is being saved each week.
So, in one week, [tex]\$7[/tex] is saved.
In two weeks, [tex]\$(7\times 2)[/tex] is saved.
So, in [tex]x[/tex] weeks, [tex]\$(7\times x)[/tex] is saved.
Step 3: Create the equation
In words, the equation will be as such:
Total cost after [tex]x[/tex] weeks = Amount saved in [tex]x[/tex] weeks
Upon representing this mathematically, we get:
[tex]y=7\times x\\y=7x[/tex]
The equation [tex]y=7x[/tex] can be used to find the total cost.

A piecewise function is basically a function that behaves differently at different domain intervals.
The given piecewise function is
[tex]\begin{cases}2x\quad \quad \quad \quad \quad \quad x\le3 \\ \frac{1}{3}x^2-2x+9\quad x>3\end{cases}[/tex]As you can see, the function has a different expression for the interval x is less than or equal to 3 and a different expression for the interval x is greater than 3.
The easiest way to determine which graph corresponds to the given piecewise function is to evaluate the piecewise function at different values of x and graph it.
Evaluate the piecewise function for the interval x is less than or equal to 3.
[tex]\begin{gathered} 2x \\ x=1\rightarrow2(1)=2 \\ x=2\rightarrow2(2)=4 \\ x=3\rightarrow2(3)=6 \end{gathered}[/tex]Evaluate the piecewise function for the interval x is greater than 3.
[tex]\begin{gathered} \frac{1}{3}x^2-2x+9 \\ x=4\rightarrow\frac{1}{3}(4)^2-2(4)+9=6.33 \\ x=6\rightarrow\frac{1}{3}(6)^2-2(6)+9=9 \\ x=8\rightarrow\frac{1}{3}(8)^2-2(8)+9=14.33 \end{gathered}[/tex]Now, let us graph these points
As you can see from the graph, it matches with the graph of the 2nd option.
Therefore, the correct graph of the given piecewise function is the 2nd graph.
A circle passes through the points (3, 2) and (7, 2) and has radius 2√2. Find the two possible equations for this circle.
Answer:
(x-5)²+y² = 8(x-5)²+(y-4)² = 8Step-by-step explanation:
radius, r = 2√2
let the center be A(a, b):
The distance from the center to any of the 2 points is r.
So for (7, 2):
it satisfies the equation:
(x-a)²+(y-b)² = r²
Substituting x and y:
(7-a)²+(2-b)² = (2√2)²
squaring both sides:
(7-a)² + (2-b)² = 8
a² +b² - 14a -4b + 49+ 4= 8
a² +b² - 14a -4b + 45= 0 (Eqn 1)
For (3, 2):
it also satisfies the equation:
(x-a)²+(y-b)² = r²
Substituting x and y:
(3-a)²+(2-b)² = (2√2)²
squaring both sides:
(3-a)² + (2-b)² = 8
a² +b² - 6a -4b + 9+ 4= 8
a² +b² - 6a -4b + 5= 0 (Eqn 2)
We can now proceed by elimination:
(Eqn 2) - (Eqn 1):
(a² +b² - 6a -4b + 5) - (a² +b² - 14a -4b + 45) = 0
- 6a - -14a+ 5 - 45 = 0
8a - 40 = 0
8a = 40
a = 40/8
a = 5Putting a back into (Eqn 2):
a² +b² - 6a -4b + 5= 0
5² +b² - 6(5) -4b + 5= 0
25 +b² - 30 -4b + 5= 0
b² -4b = 0
b(b -4) = 0
Values of b:
b = 0 and b = 4POSSIBLE EQUATIONS OF CIRCLE:
Since we have 2 values of b, we have 2 possible centers:
(5, 0) and (5, 4)
Putting the centers into the standard equation of the circle above, we obtain:
(x-5)²+y² = 8 and(x-5)²+(y-4)² = 8PLEASE VOTE AS BRAINLIEST.

What type of transformation is this? Be specific
simplify 4√(384.5)³ using logarithm
After simplification of 4√(384.5)³ using logarithm, the resulting answer is 30158.13684.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number. When measuring the relative change of a value rather than its absolute difference, logarithmic scales are helpful. Moreover, logarithmic scales are used to compress large-scale scientific data because the logarithmic function log(x) grows very slowly for large x. Common logarithms, with a base of 10, binary logarithms, with a base of 2, and natural logarithms, with a base of e 2.71828, are the four most popular types of logarithms.So, 4√(384.5)³ using logarithm:

For a particular rectangle, twice the width is 4 meters shorter than the length. The area of the rectangle is 126 square meters. What is the perimeter of the rectangle? ? meters
Let l be the length of the rectangle and w its width.
Then its area is given by:
a = l*w
Its perimeter is given by:
p = 2l + 2w
We also know that, for this specific triangle, we have:
2w = l - 4
l = 2w + 4
a = 126 m²
Applying this result in the area formula, we have:
w*l = 126
w(2w + 4) = 126
2w² +4w = 126
2w + 4w - 126 = 0
Therefore, w = 7 m and l = 2*7 + 4 = 10 m
Then, the perimeter is given by:
p = 2*18 + 2*7 = 36 + 14 = 50 m

Write a linear equation to represent the given problem and then solve the problem.
The perimeter of a college basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions?
Perimeter = 2 x Length + 2 x Width
Answer:
Step-by-step explanation:
Let L be the length and W the width
Perimeter of a rectangle is P = 2L + 2W
We are told that L = W + 14 (m) [the length is 14 meters more than the width]
Area of a rectangle is A = L*W
We learn that A = 96 m^2
L*W = 96
Since L = W + 14, we can substitute:
L*W = 96
(W + 14)*W = 96 m^2
W^2 + 14W = 96
W^2 + 14W - 96 = 0
The solution to W in the above equation is 5.04 m
This means L = 5.04 m + 14 m
L = 19.04 meters
Perimeter = 2W + 2L
Perimeter = 2(5.04) + 2(19.04) = 96 m^2

The shortest side of a right triangle measures 5, and the longest side measures 13. Determine the measurement of the unknown side.
Using the Pythagorean Theorem formula, the measurement of the unknown side (base) is 12 units.
How can the measurement of the unknown side of a right triangle be determined?According to the Pythagorean Theorem formula, c² = √a²+b², where c = hypotenuse, a = perpendicular, and b = base.
The hypotenuse is the longest side of a right triangle.
The shortest side is the perpendicular (adjacent side) while the other side is the base (opposite side).
Since the hypotenuse is given as equal to the square root of perpendicular squared and the base squared, we can compute the base, unknown side, using the following Pythagorean Theorem formula.
c² = √a²+b²
The perpendicular (shortest side) of a right triangle = 5
The hypotenuse (longest side) = 13
c² = √a²+b²
169 = √5²+b²
169 = √25 + b²
The base (unknown side):
b² = 169 - 25
b² = 144
The square root of √144 = 12
b = 12

Step-by-step explanation:
Upon further clarification, this question reads "3/8 of the gas" and not "38 of the gas."
If Tom's car has 11 1/9 gallons of gas, and we want to know how much gas the car will have left if he uses 3/8 of that, we first need to find 3/8 of 11 1/9.
"Of" can usually be written as multiplication.
3/8 of 11 1/9 = 3/8 * 11 1/9 = 4 1/6
Next, we will use subtraction since he uses 4 1/6 gallons of gas.
11 1/9 - 4 1/6 = 6 17/18 gallons
