To make 3 dinner rolls, 3/4 cup of flour is used. How many rolls can you make with 2 1/2 cups of flour?
Answer: I can make 10 rolls with 2 1/2 cups of flour
Step-by-step explanation:
3/4 cup of flour can makes 3 Dinner rolls
Therefore 2 1/2 cups of flour will make

A barrel in the shape of a circular cylinder is 30 inches in diameter and 42 inches tall.
Approximately what is the volume of the barrel in gallons?
(Use 1 gal - 231 in)
Answer: 128.5 gallons
Step-by-step explanation:
V= πr²h
V=π15²42
V= 29688.05058in³ ÷ 231 ≈ 128.5 gallons

A sports memorabilia collector needs to create a display case to show her baseball cards
at a garage sale. She will create the case in the shape of a rectangular prism with no lid.
The box will be created by cutting square corners out of a piece of cardboard with
dimensions 40 inches by 60 inches. What equation should be used to maximize the
volume of the box?
Answer:
For a box of length L, width W, and height H, the volume is:
V = H*L*W
in this case, we have a piece of cardboard of dimensions 40in by 60 in.
If we cut squares of side length X in the corners and we fold the corners, we will have a height of X.
And we can define:
Length = 60in - X
Width = 40 in - X
Then the volume of the box will be:
V = X*(60in - X)*(40in - X)
V = X^3 - 100in*X^2 + 2400in^2*X
We want to maximize this, then we need to find the zero of the first derivative.
We have that:
V' = 3*X^2 - 2*100in*X + 2400in^2
V' = 3*X^2 - 200in*X + 2400in^2
This is the equation we will use to maximize the volume of the box, but let's not end here, let's complete the problem and find the value of X and the maximum volume.
We want to solve:
V' = 0 = 3*X^2 - 200in*X + 2400in^2
For X.
Then we can use Bhaskara's formula, we will get that the solutions are:
[tex]X = \frac{-(-200in) +-\sqrt{(-200in)^2 - 4*3*(2400in)} }{2*3} = \frac{200in +- 105.8in}{6}[/tex]
Then we have two possible solutions for X.
X = (200in + 105.8in)/6 = 50.97 in
But this is larger than the side of 40 in, so we can not cut this much, we can discard this option.
The other one is:
X = (200in - 105.8in)/3 = 15.7in
This seems correct.
Then the maximum volume of the box is:
V = 15.7in*(60in - 15.7in)*(40in - 15.7in) = 16,900.893 in^3
The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.
The margin of error (E) for a confidence interval is described as:
E = z × (σ / √n)
where:
E is the desired margin of error
z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)
σ is the population standard deviation
n is the sample size
In this case, the margin of error is no more than ±1 inch, so E = 1 inch.
Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.
For a 99% confidence level, the z-score is approximately 2.576.
Plugging in the known values into the margin of error formula,
1 = 2.576 × (2.4 / √n)
To solve for n, rearrange the formula as follows:
√n = (2.576 × 2.4) / 1
√n = 6.1824
n = (6.1824)²
n ≈ 38.16
Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

-4m^2+2m-11=-5m^2
Answer:
m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46
Step-by-step explanation:
-4m² + 2m - 11 = -5m²
m² + 2m - 11 = 0
m² + 2m + 1 = 12
(m + 1)² = 12
m + 1 = ± √12
m = -1 ± 2√3

• Your bike tire has a radius (r) of 13 inches
• The period is the circumference of the tire (2 πr)
• Start the cycle when the spot is at the top of the tire
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.
What is a cosine Function?It is a function that repeats itself in a particular time interval.
You ride through some wet paint on your bike, creating a red spot on the tire.
Write a cosine equation to model the height of the red spot over the distance you ride.
Your bike tire has a radius (r) of 13 inches.
The period is the circumference of the tire (2πr).
The cosine equation is given as
y = A cos (Bx + C) + D
Where
A = the amplitude
B = time period
C = phase difference
D = shifting of central line
Then we have the diagram

Solving steps
We know x= -10-15y, so we can subtract it to the equation above
x = -10-15y
2x+5y=35
2(-10-15y) + 5y = 35
(Refer to the 1st image to solve for y)
Y = -11/5
We now know y= -11/5, so we can subtract it to the equation for x.
Y = -11/5
x = -10-15y
x = -10-15(-11/5)
(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)
x = 33 - 10
x = 23
