a) What is the area of the label of a can with dimensions as shown?
cm2
b) What is the total surface area of the can?
cm2
c) What is the volume of the soup can?
cm2
Answer:
Part a) The Labeled part of the Can ⇒ 263.76 cm^2
Part b) The Surface Area of the Can is ⇒ 340.69 cm^2
Part c) The Volume of the Can is ⇒ 38.465 * 12 = 461.58 cm^2
Step-by-step explanation:
~ If the dimensions of this can is 12 centimeters by 7 centimeters... ~
Part a)
1. Now a can is in the shape of a cylinder, thus the Base would act as a circle. That being said, 7 centimeters acts as the diameter of this circle.
2. If we were to unravel the middle of the can, it would be that this circular portion turns out of be a rectangle, with dimensions of the height of the cylinder, by the circumference of the Base of the cylinder. The circumference can be calculated by πd where d is the diameter ⇒ 3.14 * 7 ⇒ 21.98 cm. Thus the dimensions of this middle part of the can is 21.98 by 12 ⇒ 21.98 * 12 ⇒ 263.76 cm^2.
The Labeled part of the Can ⇒ 263.76 cm^2
Part b)
1. We know previously, that 7 centimeters acts as the diameter of this circle, so the radius must be half of that, which is 7/2 ⇒ 3.5 cm. Now we can apply the area of a circle formula πr^2 where r ⇒ radius, such that: 3.14 * ( 3.5 )^2 ⇒ 3.14 * 12.25 ⇒ 38.465 cm^2.
2. Knowing that the Base of this can is 38.465 cm^2, multiply this value by 2 to get the surface area of the two bases, provided they are equivalent: 38.465 * 2 ⇒ 76.93 cm^2
3. We know that this labeled section of the can is ⇒ 263.76 cm^2. This means that The Surface Area of the Can is ⇒ 263.76 + 76.93 = 340.69 cm^2
Part c )
The volume of the can is calculated by Base * height. We know from the previous questions that the Base ⇒ 38.465, and the height was given to be 12 centimeters. This means that The Volume of the Can is ⇒ 38.465 * 12 = 461.58 cm^2
What is 1/4 of a pound converted into ounces
Answer:
4 ounces.
Step-by-step explanation:
There is 16 ounces in a pound.
1/4 ounces means there is one pound that was cut into 4 pieces and you want to find how many ounces is in one of those pieces.
Since the pound is divided into 4 pieces, we have to do the same with the 16 ounces in that one pound.
16 ounces divided by 4 is 4 ounces.
1/4 of a pound converted into ounces is 4 ounces.

Mr. Smith and his family came to the USA for a visit from Melbourne, Australia. After purchasing $32.00 in clothing at a department store, he was presented with a bill for $34.36. Why did the department store charge him the additional $2.36? How did the department store compute this amount? What amount should Mr. Smith pay?
explanation plss!!
Answer:
Mr. Smith should pay the department store $32.00 plus $2.36 in sales tax for a total bill of $34.36.
Step-by-step explanation:
The department store was adding sales tax to the bill. Sales tax is a tax on goods and services purchased and is normally a certain percentage added to the buyer's cost.
Solution: 2.36 ÷ $32.00 = 0.0735. Sales tax was charged by the department store at a rate of 7.375%.
Answer: Mr. Smith should pay the department store $32.00 plus $2.36 in sales tax for a total bill of $34.36.
Sales tax rates vary from state to state. Retail sales tax rates are set by the individual states in the United States and vary from 0 to 9% of the sales price. Sales tax is usually the responsibility of the merchant to collect and submit to the state, and stated separately (or implicitly added at the time of the sale) to consumers.
The additional amount Mr. Smith paid is tax.
The amount was determined by calculating 7.4% of the items bought.
Mr Smith. should pay $34.36.
Tax is an amount of money levied by the government or an agency of the government on certain goods and services. Taxes increases the price of a good or service.
In order to determine the tax paid, divide the additional amount paid by the total cost of items purchased.
(2.36 / $32) x 100 = 7.4%

The function E(d)=0.25d√ approximates the number of seconds it takes a dropped object to fall d feet on Earth. The function S(d)=0.2⋅E(d) approximates the number of seconds it takes a dropped object to fall d feet on the sun. How long (in seconds) does it take a dropped object to fall 80 feet on the sun? Round your answer to the nearest hundredth.
Answer:
0.45 second
Step-by-step explanation:
The number of seconds it takes a dropped object to fall d feet on Earth is given as:
E(d)=0.25√d
the number of seconds it takes a dropped object to fall d feet on the sun is given as:
S(d)=0.2⋅E(d)
Therefore
S(d)=0.2 × 0.25√d = 0.05√d
Given that it take a dropped object to fall 80 feet on the sun (i.e d = 80 feet), to calculate the time in seconds we use:
S(d) = 0.05√d
S(d) = 0.05 × √80 = 0.05 × 8.944 ≈ 0.45 s
It takes 0.45 second for a dropped object to fall 80 feet on the sun
Kimberly had more time to conduct surveys and decided to survey a random sample of 30 students from the school. In Kimberly’s sample, 24 students said they would vote for Tammy. What is Kimberly’s best estimate of the number of students in the school who would vote for Tammy?
Answer:
80% of the students would vote for Tammy.
Step-by-step explanation:
To find Kimberly's best estimate, we need to use the sample the surveyed.
From the sample of 30 students, 24 said that they would vote for Tammy, so to generalize this sample, we need to find the percentage of students in the sample that would vote for Tammy:
Percentage = 24 / 30 = 0.8 = 80%
So the best estimate Kimberly can make is that 80% of the students would vote for Tammy.

3x+2x+7=8x+8
solve for x
Answer:
x = [tex]\frac{-1}{3}[/tex]
Step-by-step explanation:
The bold side will be the "first side" and the italics will be the "second side."
3x + 2x + 7 = 8x + 8
First, you add the variables from the first side of the equal sign together.
3x + 2x = 5
Now the equation becomes: 5x + 7 = 8x + 8
Then you're going to take the 7 from the first side and subtract it from the 8 on the second side.
8 / 5 x + 1
8-7 = 1
Now the equation becomes: 5x = 8x + 1
Subtract 8x from both sides
-3x = 1
Divide both sides by -3
x = [tex]\frac{-1}{3}[/tex]
Solving systems of equations algebraically.
6x + 8y = -22
y = -5

Step-by-step explanation:
Putting value of y
6x + 8(-5) = - 22
6x - 40 = - 22
6x = - 22 + 40
6x = 18
x = 18 / 6
x = 3
Adric owns 8 pairs of shoes. How many ways can he choose 4 pairs of shoes to pack into his luggage?
The answer is 70 but I don’t know how my teacher got that...
Answer:
70
Step-by-step explanation:
It is made with a combination. Combination of 4 taken from 8, the formula of the combination is as follows:
nCr = n! / (r! * (n-r)!)
In this case 8 is "n" and 4 is "r"
8C4 = 8! / (4! * (8-4))!
8C4 = 8! / (4! * 4!)
8C4 = 40320/576
8C4 = 70

Which polygon has an interior angle sum of 1260°? A polygon has 7 sides. A polygon has 8 sides. A polygon has 9 sides. A polygon has 10 sides.
Answer:
9 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Equating to 1260 gives
180° (n - 2) = 1260 ( divide both sides by 180 )
n - 2 = 7 ( add 2 to both sides )
n = 9
Thus a polygon with 9 sides
A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain. The correct option is C.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of all the interior angles of an 'n' sided polygon is given by the formula,
Sum of all the interior angles = (n-2) × 180°
Given that the sum of the interior angle is 1260°. Therefore, the number of sides n can be calculated as,
1260° = (n-2) × 180°
7 = n - 2
n = 7 + 2
n = 9
Hence, the number of sides the given polygon has is 9.

Which of the following is the correct factorization of the polynomial below?
3p^2-15pq+20q^2
Answer:
The polynomial is irreducible.
Step-by-step explanation:
The polynomial 3p²-15pq+20q² can be factored as (p-2q)(3p-10q).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The polynomial is given as follows:
3p²-15pq+20q²
It is required to find the factorization of the given polynomial.
The greatest common factor (GCF) of the coefficients (3, -15, 20), is 3.
Rewrite the polynomial using the GCF of 3. We get:
3(p²-5pq+6q²)
We need to find two numbers that multiply to 6q² and add to -5pq.
The numbers are -2q and -3p.
Combine the factored quadratic expression with the GCF of 3.
3(p-2q)(p-3q)
Therefore, the correct factorization of the polynomial 3p²-15pq+20q² is 3(p-2q)(p-3q).

lin and diego are discussing two expressions x^2 and 2^x
Answer:
The expression a^b
means that we multiplicate the number a by itself b times.
So x^2 means that we multiplicate the number x by itself 2 times:
x^2 = x*x
and 2^x means that we multiplicate the number 2 by itself x times
2^x = 2*2*2*....*2 (if you count them, you should see x times the number 2)

Every day the teacher has her class of ten students line up for lunch. How many different ways can the students line up?
3,628,800
100
55
90
The number of different ways ten students can line up for lunch is 3,628,800, which is found by calculating the factorial of 10 (10!).
The question asks how many different ways ten students can line up for lunch. This is a problem of calculating permutations without repetition, as each student is unique and once a student takes a place in line, they cannot be in another position at the same time. The formula to calculate the number of permutations for 'n' unique items is n! (n factorial), which is defined as the product of all positive integers from 1 to n.
In this case, 'n' is 10 because there are 10 students. Therefore, the calculation is 10! = 3,628,800 different ways.
