Austin uses a mold to make cone-shaped cupcakes. The diameter of the mold is 12 inches, and
the height of the mold is 10 inches. If one cubic inch is about 0.55 ounce, how many ounces will
2 cupcakes weigh? Use 3.14 for T. Round to the nearest tenth of an ounce. Only write the
number
Answer:
25.9
Step-by-step explanation:
So calculate volume of the mold, which is a cone: (pi) r2 (h/3) where r is radius and h is height
So diameter/2 = r which is 1.5 in
h = 2 in
V = (3.14)(1.52)(2/3) = 4.71 in3
If 1 in3 = 0.55 oz, and 1 mold = 4.71 in3, then one mold = 2.59 oz
2.59 oz * 10 cupcakes = 25.9 oz total
Step-by-step explanation:
the volume of a cone is
pi×r² × h/3
the radius is always half of the diameter, so, it is here
12/2 = 6 in.
h = 10 in.
so, we have here
pi×6²×10/3 = 3.14 × 36 × 10/3 = 3.14×120 = 376.8 in³.
2 cupcakes have then
376.8 × 2 = 753.6 in³
1 in³ = 0.55 ounces
so, the weight of 2 such cupcakes is
0.55 × 753.6 = 414.48 ounces ≈ 414.5 ounces

I graphed it on desmos:
The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0
Length be x
width be x-5
So
Area=Length×Breadth
x(x-5)=750Or
If x turned y
y(y-5)=750750-y(y-5)=0Option C
Option A can be true as per commutatI've property
y²-5y=750Option B is true
Answer:
y² - 5y = 750
750 - y(y - 5) = 0
(y + 25)(y - 30) = 0
Step-by-step explanation:
Formula
Area of a rectangle = length × width
Given:
y = length of the room(y - 5) = width of the room750 ft² = area of the roomSubstituting the given values into the formula and rearranging in different way:
Equation 1
⇒ 750 = y(y - 5)
⇒ y(y - 5) = 750
⇒ y² - 5y = 750
Equation 2
⇒ 750 = y(y - 5)
⇒ 750 - y(y - 5) = 0
Equation 3
⇒ 750 = y(y - 5)
⇒ y(y - 5) - 750 = 0
⇒ y² - 5y - 750 = 0
⇒ y² - 30y + 25y - 750 = 0
⇒ y(y - 30) + 25(y - 30) = 0
⇒ (y + 25)(y - 30) = 0
The circumference of a circle is approximately 43.96 centimeters. what is the radius of the circle? use 3.14 for radius.
Answer:
7 cm
Step-by-step explanation:
The circumference of a circle is given in terms of its radius by the formula ...
C = 2πr . . . . where r represents the radius
__
Using the given values in the formula, we can find the radius to be ...
C/(2π) = r
43.96/(2×3.14) = r = 7 . . . . cm
The radius of the circle is 7 cm.

what is the rate change of the table?
The rate of change is $27 per month if the change in y values is 54 and change in x values is 2.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
From the data given in the table, we can find the rate of change per month:
To find the rate of change:
= change in y/ change in x
= (138-84)/(4-2)
= 54/2
= 27 per month
Thus, the rate of change is $27 per month if the change in y values is 54 and change in x values is 2.

Thirteen earthquakes were measured using the Richter scale. Their magnitudes are listed below. What is the range for this data set?
8.2, 3.1, 5.9, 2.5, 6.2, 5.1, 7.6, 9.3, 8.1, 7.4, 7.8, 6.5, 8.7
A. 6.8
B. 2.6
C. 4.1
D. 5.6
The range is found by subtracting the smallest data value from the largest data value. Here, the smallest data value is 2.5 and the largest is 9.3. Therefore, the range is:
[tex]9.3 - 2.5 = 6.8[/tex]
Therefore, the answer is Option A.

The variance:1. The steps that follow are also needed for finding the standard deviation. Start by writing the computational formula for the variance of a sample:
[tex]{s^2}= \frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n-1}[/tex]
2. Create a table of 2 columns and 14 rows. There will be a header row and a row for each data value. The header row should be labeled with x and x^2. Enter the data values in the x column, with each data value in its own row. In the second column, put the square of each of the data values, x^2.

3. Find the sum of all the values in the first column, [tex]{\sum}{x}[/tex].
[tex]\sum{x} = 86.4[/tex]
4. Square the answer from step 3, then divide that number by the size of the sample.

5. Find the sum of all the values in the second column, [tex]{\sum}{x^2}[/tex].
[tex]{\sum}{x^2} = 625.76[/tex]
6. Subtract the answer in step 4 from the answer in step 5.
[tex]{\sum}{x^2} - \frac{({\sum}{x})^2}{n} = 625.76 - 574.22769230769 = 51.532307692308[/tex]
7. Divide the answer in step 6 by n - 1, one less than the size of the sample. This answer is the variance of the sample.
[tex]{s^2}= \frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n-1} = \frac{ 51.532307692308 }{12} = 4.294358974359[/tex]
Standard DeviationTo find the standard deviation, first write the computational formula for the standard deviation of the sample.
[tex]{s}= \sqrt{\frac{{\sum}{x^2} - \frac{({\sum}{x})^2}{n}}{n - 1}}[/tex]
Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by [tex]s[/tex]. Here, we round the standard deviation to at most 4 decimal places.

Justin earns an annual salary of $48,000, which is paid monthly. This month Justin had the following deductions:
Federal and state income taxes
$650
Social Security and Medicare taxes
$248
Health insurance premiums
$350
Retirement plan contribution 5% of salary
What is Justin's net pay for the month?
Answer:
$2552
Step-by-step explanation:
First you have to find Justin's monthly salary. You do this by dividing his annual salary by 12 months. 48000/12 = 4000 This means Justin makes $4000 each month. Next we have to find what 5% of that is, in order to know how much his retirement plan contribution costs. To do this you divide 4000 by 100 to know how much 1% of his monthly salary is, and then you multiply that by 5 to know how much 5% of his monthly salary is. 4000/100 = 40 40x5 = 200 .We now know his retirement plan contribution each month costs $200. Now we need to know how much to subtract from his monthly salary to get his net pay for the month. We can do this by adding all of his monthly expenses together and then subtracting that total from 4000. 650+248+350+200 = 1448 4000-1448 = 2552 Justin's net pay for the month is $2552
Please help me solve for Z
The correct value of z in this figure is 190⁰
The image given in this question is of a circle. To solve it, let's calculate it as an equation of the first degree.
– First, let's: add the data that are on the circle and equate the equality as 360⁰, which is the value of the degree of a circle.
145 + 24 + z = 360⁰
– Now, let's: add the natural terms to each other. And finally, we'll isolate z and subtract 360⁰ by the number that's left.
145 + 24 + z = 360⁰
170 + z = 360⁰
z = 360⁰ - 170
z = 190⁰
So, the value of z, will be 190⁰

C(x)=2300+60x
R(x)=820x−x2
Answer:
$ 142100
Step-by-step explanation:
Profit is the difference between the revenue and the cost
P(x) = R(x) - C(x)
= 820x - x² - (2300 + 60x)
= 820x - x² - 2300 - 60x
= -x² + 820x - 60x - 2300
P(x) = -x² + 760x - 2300
We can find the maximum profit of the company by finding the maximum of the parabolic function.a = -1 ; b = 760 and c = -2300
[tex]\sf \boxed{P_{max} = c - \dfrac{b^2}{4a}}[/tex]
[tex]\sf = -2300 - \dfrac{760^{2}}{4*(-1)}[/tex]
[tex]\sf = -2300 +\dfrac{577600}{4}\\\\ = -2300 + 144400\\= 142100[/tex]
[tex]\sf \boxed{P_{max}= \$ 142100}[/tex]

Malik randomly selects 60 students at Williams High School about their favorite flavor of milkshake. Of the students selected, 24 identified chocolate as their favorite milkshake. There are 1,990 students at Williams High School. Based on the data, what is the most realistic estimate for the number of students at Williams High School whose favorite ice-cream is Chocolate? A. 60 Students, B. 796 Students, C. 1,194 Students, or D. 1,400 Students?
Answer:
B
Step-by-step explanation:
The answer is B as this is a simple ration question.
All you need to do is convert the question into ration fraction form:
24/60 =x/1990
x is the number of people whose favourite ice-cream is chocolate.
Do cross multiply on both sides and you will get 47760=60x.
x= 796.
Thus, you get your answer.
