Answer:
56.5
Step-by-step explanation:
The length of the paper around the can is equal the circumference of the base.
Circumference = πd
Circumference = 3.14 * 4
Circumference = 12.56
And since the height is 4.5 (which is also the width of the paper if you unwrap it), Multiply the circumference by 4.5.
12.56 * 4.5
= 56.52
Jerry has invested $1500 into a savings account that paid him 8.25% interest, what will the balance of his account be after 6 years?
Please Explain!
answer: $2413.50
y=original amount of money(1+ the percent divided by 100)^the number of years is the power
we do this with the 1+ ... because the original amount plus the extra 8.25%
so the equation would be ...
y=1500(1+0.0825)^6
y=1500(1.60904218428)
y=1500(1.609) (I rounded)
y=$2413.50
What is the mean of this data set? 12,17,16,10,20,13,14,14,12,12,19,18
Answer:
14.75 :) please give me brainliest :)
Step-by-step explanation:
Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers up. In this case, we would add
12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177
STEP 2: Divide the sum of the number by the number of digits you added.
We would divide 177 "sum of numbers" by 12 "number of digits" and would
get a quotient of 14.75
The mean for this set of data is 14.75
How many times does 12 go into 32
Answer: the answer is 2
Step-by-step explanation:
12 x 2 is 24
12 x 3 is 36
so it goes into 32, 2 times.
Final answer:
12 goes into 32 a total of 2 full times with a remainder of 8, which can also be expressed as 2 and 2/3 times. The calculation is done using long division.
Explanation:
The question asks how many times does 12 go into 32. This is a division problem where you need to divide 32 by 12. To calculate this, you can use long division. Dividing 32 by 12 gives you 2 with a remainder of 8, since 12 times 2 is 24 and 32 minus 24 leaves 8. Therefore, 12 goes into 32 2 full times with 8 left over, or 2 remainder 8.
Another way to express this is in terms of decimal or fractions. Since 8 is 2/3 of 12, you can also say that 12 goes into 32 2 and 2/3 times. However, if you are strictly looking for how many full times 12 can divide into 32 without considering fractions, the answer is simply 2.
Kenisha tried to subtract two polynomials her work is shown below. At which step did Kenisha make an error, If at all?
A. Step 1
B. Step 2
C. Step 3
D. Kenisha’s work is correct
Answer:
Step 1
Step-by-step explanation:
When you subtract a polynomial in parentheses, you have to remove them from the parentheses first, which Kenisha did right. The problem is that because the numbers are being subtracted, all of the signs switch, which they forgot to do. Step one should look like: 2b² + 3b + 11 - 7b² + 5b - 1

Answer:
f(x) = 3x - 1
Step-by-step explanation:
The line can be represented in the form f(x) = mx + b, where m is the rate of change of the line and b is the value of the function when x = 0.
Looking at the graph, we can tell that when x = 0 the function = -1. (The point on the line and the y-axis).
We can also tell that when x increases by 1, y increases by 3. The points (0,-1) and (1, 2) are both on the line and their difference in x is 1 and their difference in y is 3.
The formula for slope (rate of change) is [tex]\frac{change\ in\ y}{change\ in\ x}[/tex], so m = [tex]\frac{3}{1}[/tex] or 3.
Now we have the equation for the line is f(x) = 3x - 1

How is using the Pythagorean theorem in a rectangular prism similar to using it in a rectangle
The Pythagorean theorem is used in a similar manner to compute the diagonal of a rectangle and a rectangular prism. In both cases, the theorem is utilized to find the length of a line connecting two opposite corners across the shape or space.
Explanation:In the field of Mathematics, the Pythagorean theorem presents a fundamental relationship within a right triangle which expresses that the square of the hypotenuse (the side opposite the right angle) is equivalent to the sum of the squares of the other two sides. This theorem is represented mathematically as a² + b² = c².
When applying this theorem in a rectangle, consider a diagonal drawn from one corner to the opposite corner, which gives us a right triangle. To find the length of this diagonal (hypotenuse), we use the Pythagorean theorem, considering the two sides of the rectangle as the other two sides of the triangle.
In a rectangular prism, the same principle applies. However, instead of two sides (as in a rectangle), we now have three dimensions (length, width, and height) to consider. When one wishes to find the distance from one corner to the opposite corner (a diagonal cutting through the prism), the Pythagorean theorem can be employed. First, a right triangle is considered in the base of the prism, and the Pythagorean theorem is used to find the length of the diagonal of the base. Next, a second right triangle is constructed using the height of the prism and the diagonal of the base. Once again, the Pythagorean theorem can be implemented to calculate the length of the longest diagonal of the prism.

The Pythagorean theorem applies similarly in both rectangular prisms and rectangles, using right triangles to calculate distances.
The Pythagorean theorem is fundamentally the same in both a rectangular prism and a rectangle, as it relies on the properties of right triangles. For a rectangle, the theorem states that the sum of the squares of the two shorter sides (a and b) equals the square of the hypotenuse (c), or a² + b² = c².
When applied to a rectangular prism, the theorem is used in three dimensions to find the length of the diagonal (d) stretching between opposite corners. In a rectangular prism, by applying the Pythagorean theorem successively across two-dimensional planes, we first calculate the diagonal of one face of the prism (b² = x² + y²).
Then, we incorporate the third dimension z to find the space diagonal: d² = x² + y² + z². This sequential application of the Pythagorean theorem leverages its two-dimensional principle to solve for three-dimensional distances.
Steps to Apply Pythagorean Theorem in a Rectangular Prism:
Identify the three side lengths of the prism: x, y, and z.Calculate the face diagonal using: b² = x² + y².Apply the theorem again to incorporate the third dimension: d² = x² + y² + z².This demonstrates how the Pythagorean theorem's consistent application in both two and three dimensions allows calculation of diagonals and distances in various geometric contexts.

Mr. McGee mowed 4/5 of his lawn. His three sons finished the mowing. Each son mowed the same amount. How much of the lawn did each son mow?
Answer:
1 fifteenth, or 1/15
Step-by-step explanation:
If there are 3 sons multiply the fraction by 3 and then you have 12/15 because 12/15 is equal to 4/5, so the remaining is 3 out of 15, so divide that between the 3 sons and boom, 1/15th per son.

Omar makes a total of $51.75 selling brownies and muffins at a bake sale if he sells 16 brownies for $2.25 each how many muffins does he sell at $1.75 each?
Answer:
He can make 9 Muffins
Step-by-step explanation:
16*2.25=36
51.75 - 36=15.75 Subtract the total number of selling he made by how much he made with the brownies
15.75/1.75=9 Divide the number you got after subtracting by by how many he is going to sell each of then
Omar made $36 from selling brownies. He made $15.75 from selling muffins, and since each muffin cost $1.75, he therefore sold 9 muffins at the bake sale.
Explanation:To solve this problem, we must first find the total money Omar made from selling brownies. We do this by multiplying the price of each brownie ($2.25) by the number of brownies sold (16), which gives $36. Then we subtract this total from the total money Omar made ($51.75) to find out how much money he made from selling muffins, which is $51.75 - $36 = $15.75.
Next, we divide this amount by the price of each muffin ($1.75) to find out the number of muffins sold, as follows: $15.75 ÷ $1.75 = 9.
So, Omar sold 9 muffins at the bake sale.

Area: 4069.44
Circumference: 226.08
Step-by-step explanation:
The equation for the area of a circle is:
pi(r^2)
So they told us to use 3.14 for pi, the r (radius)is found by dividing the diameter (72) by 2 since
r = d/2
r = 72/2 = 36
plug this into the equation for the area of a circle:
3.14(36^2) = 4069.44
——————————————————————————————————
To find the circumference, use the equation for it:
2 x pi x r or pi x d
Let’s use the second equation, since the diameter is already given
2(3.14)(72) = 226.08
Answer:
Area is 4069.44 m². Circumference is 226.08 m.
Step-by-step explanation:
Area:
a = r²π
a = 36²π
a = 4069.44
Circumference:
c = dπ
c = 72 × 3.14
c = 226.08
The cost to manufacture x pairs of sunglasses can be represented by a function, C(x). If it cost 398 to manufacture 4 pairs of sunglasses, which of the following is true
a) c(4)=99.50
b) c(398)=4
c) c(4)=398
d) c(99.50)=1
can someone solve it and show steps please
The correct answer is c) C(4) = 398, which appropriately links the cost of manufacturing 4 pairs of sunglasses ($398) with the function C(x).
Explanation:The function C(x) represents the cost to manufacture x pairs of sunglasses.
Given that it costs $398 to manufacture 4 pairs, we can substitute these values into the function to find which statement is accurate.
The logic behind this is simple: C(x) is typically understood to be the cost associated with producing x units.
Therefore, when x is the number of units produced, C(x) is the total cost to produce those units.
Substituting 4 into the function C(x) would give us the total cost for 4 pairs of sunglasses.
Thus, we can say C(4) = 398. This matches response option c), which states that C(4) = 398, and is therefore true.
Response options a), b), and d) all incorrectly mix up the inputs and outputs of the cost function and therefore can be disregarded.
