Answer:
5%
Step-by-step explanation:
22.05-21=1.05
1.05/21=.05
.05*100=5%
The sales tax is 5% of listed price.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, Luke went shopping for a new pair of pants.
The listed price of the pair of pants was $21.
But the price with tax came to $22.05.
The taxed amount
= $22.05 - $21
= $1.05
To find the percentage of taxed amount:
We use the percentage formula,
let m be the required percentage.
So,
1.05 = m x 21 /100
m = 1.05 x 100 / 21
m = 105 /21
m = 5%
Therefore, taxed amount is 5% of original price.

The equation of the scenario is y = 3/2x + 4 and the scenario is not a proportional function
How to determine the equation of the scenario?From the scenario, we have:
Base distance = 4
Rate = 3 miles every 2 hours
So, the function is:
y = 3/2x + 4
Where x represents the time and y represents the distance travelled
How to complete the table?When x = 0, we have:
y = 3/2(0) + 4 = 4
Using other values of x, we have:
y = 3/2(1) + 4 = 5.5
y = 3/2(2) + 4 = 7
y = 3/2(3) + 4 = 8.5
y = 3/2(4) + 4 = 9
So, the complete table is:
x Process y
0 3/2(0) + 4 4
1 3/2(1) + 4 5.5
2 3/2(2) + 4 7
3 3/2(3) + 4 8.5
4 3/2(4) + 4 9
Is the scenario a proportional function?No, it is not a proportional function, because when x = 0, the value of y is not 0

What is the total surface area of the figure?
Answer:
531 in²
Step-by-step explanation:
5 faces of the cube are facing the surface because the top one is shared with the triangular prism.
Surface area of a cube is S = 5 × (9)²
S = 405 in²
Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).
S = (1/2)7×(4×9)
S = 126 in²
Add 126 + 405 to get 531 in²

A standard die is a cube with sides measuring 15 mm. What is the volume of the die?
Answer:
3375mm^3
Step-by-step explanation:
15*15=225
225*15=3375
3375mm^3 is the volume of the die.
Answer:
3,375mm²
Step-by-step explanation:
Since each side of a cube is the same length, that means that we will just have to do 15mm*15mm*15mm to get our answer.
V = L x W x H
= 15 x 15 x 15
= 3,375
Hence, the volume of the die is 3,375mm²

Imagine you live in a big country. There are no forests in your country, but there are lots of farms and lots of food. The country next door is full of forests. This country also doesn’t have enough food, so it wants to cut a lot of the forests down to make farms. If the neighboring country does this, it will change the climate of your country, making it drier. What do you think would be a good solution to this problem?
Trading your food for the neighboring country's wood. You can control how much wood they cut down, slowing down the change of climate in your country, and can help them with their food shortage at the same time.

Jacob is building a square pyramid for a class project. He needs to cover the entire pyramid in aluminum foil. The base of the pyramid has a perimeter of 76 centimeters. The slant height of each triangular side is 28 centimeters. What is the surface area, in square centimeters, of Jacob's pyramid?
Answer:
The surface area of Jacob's pyramid is 1425cm²Step-by-step explanation:
Step 1
Find the dimensions
We will be finding the dimensions to find the surface area. We know on what is the perimeter of the square base, and what is the slant height of each triangle. So that's enough to know, if we know the perimeter, of the square base, we can divide that by 4 to get our 1 side's length. Then, we can calculate the square base's SA and the Triangle's SA!
76/4=19
Now we have our dimensions ready!
Square Base each side length: 19 centimeters
Triangle slant height for each single: 28 centimeters
Step 2
Figure out the SA's now!
Now, let's figure out all the SA's.
First the square base!
19x19=361cm²
Now, let's figure out the SA for all of the triangles
As we know, to find the Area or Surface Area (SA) of each triangle, we have to use this formula:
[tex]SA=\frac{1}{2} *B*H[/tex]
But to find the surface area of 4 triangles at once, we will have to use this formula:
[tex]SA=2*B*H[/tex]
Let's do it now!
[tex]SA=2*19*28\\=2*532\\=1064[/tex]
1064cm²
Step 3
Add all the SA's up to get FINAL ANSWER!
Easy peasy lemon squeasy! Let's get on it people!
361+1064=1425cm²
The surface area of Jacob's pyramid is 1425cm²

find the areas of the trapezoids
Answer:
A = 7.5in^2
Step-by-step explanation:
Your a (base) is 4, which is A-P.
Your b (base) is 1, which is T-R.
Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.
Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)
That equals 7.5.
