The bakers at Healthy Bakery can make 180 bagels in 5 hours. How many bagels can they bake in 22 hours? What was that rate per hour?
Answer:
34
Step-by-step explanation:
Answer:
Step-by-step explanation: 180 bagels
The unit rate, in bagels per hour, is ---------------------- = 36 bagels/hour
5 hours
In 22 hours, the bakery can bake (36 bagels/hour)(22 hours) = 792 bagels
2x + 3y = 2
Consider the system
3x + 3y = -6
Describe how to solve the system by multiplying the first equation by a constant and subtracting. Why
would this method be less than ideal?
(select) v the first equation by 1.5 and subtract. This would be less than ideal because you would
introduce (select) into the solution process.

Which of the following statements about the similarity between rectangles and squares is not true?
Both rectangles and squares are quadrilaterals.
Both rectangles and squares have two sets of parallel sides.
Both rectangles and squares have four right angles.
Both rectangles and squares have four sides of equal length.
Answer:
Both rectangles and squares have four sides of equal length.
Step-by-step explanation:
Rectangle and square are the geometrical figures having four sides. They are the quadrilaterals with four sides. A rectangle is the quadrilateral in which opposite sides are equal. In a square all the sides are of equal length. The sides of both the rectangle and square are parallel. All angles form the right angles.
Find the surface area of the cylinder.
Answer:
1188 inches
Step-by-step explanation:
Answer:
The surface area of the cylinder with a radius of 7 and height of 20 would be 1186.92.
Step-by-step explanation:
The formula as given by the image is
h=20, r=7.
Substitute your radius and height as follows:
SA=[tex]SA=2*pi*r^2+2pi*r*h\\(2*3.14*7^2)+(2*3.14*7*20)[/tex]
And now solve!
307.72+879.2=1186.92
The answer would be 1186.92

The radius of a baseball is approximately 2.5 inches. What is its volume?
Answer:Below
Step-by-step explanation:
A baseball is round.
So, the diameter and the height are the same.
The radius is half of the diameter, so: 2.5 x 2 = 5
The height is also 5.

Guide Questions:
1. How do you saive for the area of the shaded region in figure A?
2. How do you solve for the area of the shaded region in figure B?
3. Is method finding the shaded region in figure A and B the same? Why? or Why not?
please answer on 3 i need answers for that number 3 questions
Answer:
1. The area is found by using the formula for a rectangle
The area is 150 cm²
2. The area is found by the definite integral for the area between two points under a curve
3. The methods are different
The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points
Step-by-step explanation:
1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure
From the question, we have;
The area of the rectangular figure, A = Length × Breadth
The length of the figure = 15 cm
The breadth of the rectangular figure = 10 cm
Therefore, we have;
A = 15 cm × 10 cm = 150 cm²
The area of the rectangular figure, A = 150 cm²
2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;
[tex]f(x) = e^{-t^2}[/tex]
Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]
Using a graphing calculator, we have;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]
3. The method of finding the area of figure A is different from the method of finding the area of the figure B
The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

The manufacturer of a certain brand of aluminum foil claims that the amount of foil on each roll follows a Normal distribution with a mean of 250 ft2 and a standard deviation of 2 ft2. To test this claim, a restaurant randomly selects 10 rolls of this aluminum foil and carefully measures the mean area to be ¯ = 249.6 ft2
Find the probability that the sample mean area is 249.6 ft2 or less if the manufacturer’s claim is true
Answer:
Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074
Step-by-step explanation:
The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²
The standard deviation of the measured amount of foil per roll, σ = 2 ft.²
The number of rolls tested by the restaurant, n = 10 rolls
The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6
Taking the sample means as individual score, we have;
The z-score, of the sample mean is given as follows;
[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]
At [tex]\overline x[/tex] = 249.6, we have;
z = (249.6 - 250)/2 = -0.2
Therefore, the probability for a mean less than or equal to 249.6, we have;
The probability, P = P(z < -0.2) = 0.42074
The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.

Step-by-step explanation:
Justin wants to buy a new pair of jeans. If the jeans were originally $50.00, but are on sale with a 30% discount, how much will Justin have to pay for the jeans?
Original price of jeans=$50
Since there is a discount of 30%
So we take 100%-30%=70%
hence to find the price Justin have to pay after discount, we take $50x70/100=$35
Therefore Justin has to pay $35 for the jeans after discount.
Find the common difference, d, given that 8x-3, 4x+1, 2x-2 are consecutive terms of an
arithmetic sequence.
A)1/6
B) -10
C) 10
D) 5
Answer:
B
Step-by-step explanation:
We are given that:
[tex]8x-3, \, 4x+1, \text{ and } 2x-2[/tex]
Are consecutive terms of an arithmetic sequence.
And we want to determine the common difference d.
Recall that for an arithmetic sequence, each subsequent term is d more than the previous term.
In other words, the second term is one d more than the first term. So:
[tex]4x+1=(8x-3)+d[/tex]
And the third term is two d more than the first term. So:
[tex]2x-2=(8x-3)+2d[/tex]
We can isolate the d in the first equation:
[tex]-4x+4=d[/tex]
As well as the second:
[tex]-6x+1=2d\Rightarrow \displaystyle -3x+\frac{1}{2}=d[/tex]
Then by substitution:
[tex]\displaystyle -4x+4=-3x+\frac{1}{2}[/tex]
Solve for x:
[tex]\displaystyle -x=\frac{-7}{2}\Rightarrow x=\frac{7}{2}[/tex]
The isolated first equation tells us that:
[tex]d=-4x+4[/tex]
Therefore:
[tex]\begin{aligned} \displaystyle d&=-4\left(\frac{7}{2}\right)+4\\&=-2(7)+4\\&=-14+4\\&=-10 \end{aligned}[/tex]
Our final answer is B.
Answer:
B.) - 10 is the answer.

Cu cat este mai mare suma numerelor 25 si 17 față de diferența lor? ( se vor folosi doua paranteze mici.)
Given :
Two numbers 25 and 17.
How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)
To Find :
How much larger is the sum of the given numbers as compared to their difference.
Solution :
Sum of given numbers, S = 25 + 17 = 42 .
Difference of given numbers, D = 25 - 17 = 8 .
The difference between S and D is, S - D = 42 - 8 = 34 .
Therefore, sum of the numbers is larger by 34 than in difference.
