Dmitri wants to cover the top and sides of this box with glass tiles that are 1 cm square.How many tiles will be need?
Answers
Dmitri needs 854 glass tiles to cover the top and sides of the box.
Given the dimensions of the box, where Length (L) = 13 cm, Width (W) = 20 cm, and Height (H) = 9 cm, we can find the surface area of the box using the formula for the surface area of a cuboid:
[tex]\[ \text{Surface Area} = L \times W + 2 \times L \times H + 2 \times W \times H \][/tex]
Substitute the values:
[tex]\[ \text{Surface Area} = 13 \times 20 + 2 \times 13 \times 9 + 2 \times 20 \times 9 \][/tex]
[tex]\[ \text{Surface Area} = 260 + 234 + 360 \][/tex]
[tex]\[ \text{Surface Area} = 854 \, \text{cm}^2 \][/tex]
Now, since each glass tile is 1 cm square, the number of tiles needed is the total surface area divided by the area of each tile:
[tex]\[ \text{Number of tiles} = \frac{\text{Surface Area}}{\text{Area of one tile}} \][/tex]
[tex]\[ \text{Number of tiles} = \frac{854}{1} \][/tex]
[tex]\[ \text{Number of tiles} = 854 \][/tex]
Therefore, Dmitri needs 854 glass tiles to cover the top and sides of the box.
Complete Question: Dmitri wants to cover the top and sides of the box shown with glass tiles that are 1cm square. How many tiles does he need? ( The length is 13cm, the width is 20cm and the height is 9cm).

D) x(75 - 25)
Explanation:
Use distribution to simplify:
x · 75 = 75x
x . 25 = 25x
75x - 25x
75x - 25x = 50x
Answer:
C and D
Step-by-step explanation:
75x - 25x
75 - 25 = 50
Write in terms of x
50x
Find the options that match this answer
a: 50 (not always equal to 50x)
b: 100 (not always equal to 50x)
c: 50x (always equal to 50x)
d: x ( 75 - 25 ) = x ( 50) = 50x (always equal to 50x)
C and D are equivalent to the answer, 50x

Two different websites offer the same watch for sale. The watch costs $45 on both sites. The site, Watches for Less charges a shipping fee of 4% of the cost of the watch. The site, Tick Tock charges 2.5% of the cost of the watch for shipping. How much less will the total cost of the watch be if purchased from Tick Tock?
Round your answer to the hundredths place.
Answers
Final answer:
The total cost of the watch will be $0.67 less if purchased from Tick Tock.
Explanation:
To find out how much less the total cost of the watch will be if purchased from Tick Tock, we need to calculate the shipping fee for both websites and subtract that amount from the total cost.
For Watches for Less, the shipping fee is 4% of $45, which is $1.80.
For Tick Tock, the shipping fee is 2.5% of $45, which is $1.13.
Therefore, the total cost of the watch from Tick Tock will be $45 - $1.13 = $43.87. The total cost from Watches for Less will be $45 - $1.80 = $43.20.
The difference in the total cost is $43.87 - $43.20 = $0.67.
Therefore, the total cost of the watch will be $0.67 less if purchased from Tick Tock.
Harry bought a used dirt bike for $1,050. Before purchasing the bike, Harry had a total of
$2,250 in his savings account. What percentage of his savings account did Harry spend on
the dirt bike?
Answers
Answer:
. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Step-by-step explanation:
Final answer:
Harry spent 46.67% of his savings on the dirt bike, calculated by dividing the price of the dirt bike by the amount in his savings account and then multiplying by 100.
Explanation:
The question is asking how to calculate the percentage of Harry's savings that was spent on a dirt bike. To find the percentage, you would divide the amount spent on the dirt bike by the total amount in the savings account and then multiply by 100. Harry spent $1,050 on the dirt bike and had $2,250 in his savings account originally.
Here's the step-by-step calculation:
Divide the cost of the dirt bike by the total savings: $1,050 / $2,250.You get a decimal result from step one, which you then multiply by 100 to get a percentage.The calculation is ( $1,050 / $2,250 ) × 100 = 46.67%.Therefore, Harry spent approximately 46.67% of his savings on the dirt bike.The ratio of side lengths for two similar cubes is į.

a. the perimeter of one face of the smaller cube compared to the perimeter of one face of the larger
cube
b. the total surface area of the smaller cube compared to the total surface area of the larger cube
c. the volume of the smaller cube compared to the volume of the larger cube
Answers
The ratio of the perimeter of one face for the two cubes is 1/2, the ratio for the total surface area is 1/4, and the ratio for the volume is 1/8.
Explanation:The student wants to find the ratios of the perimeter of one face, the total surface area, and the volume of two similar cubes having side length ratio of 1/2.
Perimeter of one face: Since each face of a cube is a square, the perimeter is 4 times the side length. As the ratio of side lengths is 1/2, the ratio of the perimeters would also be 1/2. This is because perimeter is a one-dimensional measure, therefore the ratio stays proportional to the side length.Total Surface Area: The total surface area of a cube is 6 times the area of one face (a square). Since the area is a two-dimensional measure, it's proportional to the square of the side length ratio, hence the ratio of the surface areas of two similar cubes would be (1/2)² = 1/4.Volume: The volume of a cube is the cube of the side length. Since the volume is a three-dimensional measure, it is proportional to the cube of the side length ratio, so the ratio of the volumes of two similar cubes would be (1/2)³ = 1/8.Learn more about Ratio of Similar Cubes here:

Solve the inequality:
8 + 4x ≥ 12
A. x ≥ 1
B. x ≥ 5
C. x ≤ 5
D. x ≤ 1
Answers
Answer:
x ≥ 1
Step-by-step explanation:
8 + 4x ≥ 12
Subtract 8 from each side
8-8 + 4x ≥ 12-8
4x ≥ 4
Divide by 4
4x/4 ≥ 4/4
x ≥ 1
The solution to the inequality 8 + 4x ≥ 12 is x ≥ 1. Therefore, the correct answer is A. x ≥ 1.
Correct option is A.
To solve the inequality 8 + 4x ≥ 12, we need to isolate x. Here's how we do it step by step:Start with the given inequality: 8 + 4x ≥ 12.First, subtract 8 from both sides of the inequality to isolate the term with the variable:8 + 4x - 8 ≥ 12 - 8.Simplify both sides:4x ≥ 4.Now, divide both sides by 4 to solve for x:(4x)/4 ≥ 4/4,x ≥ 1.So, the solution to the inequality is:x ≥ 1.Now, let's match this solution to the given answer choices:A. x ≥ 1 - This matches our solution.B. x ≥ 5 - This is not correct.C. x ≤ 5 - This is not correct.D. x ≤ 1 - This is not correct.The correct answer is A. x ≥ 1.For more questions on inequality -

Answer:
The system of equations as described:
y = (-3/4)x + 3
y = -12
Combining two equations, we have:
=> -12 = (-3/4)x + 3
=> -15 = (-3/4)x
=> x = -15 x (-4/3) = 20
=> Solution is (20, -12)
=> Option A is correct.
Hope this helps!

Step By Step:
The equations given to us are:
y = (-3/4)x + 3
y = -12
Now that we have y we can change that to -12
-12 = (-3/4)x + 3
-15 = (-3/4)x
x = -15 x (-4/3) = 20

A simple example of the ellipse in our daily life is the shape of an egg in a two-dimensional form and the running tracking in a sports stadium.
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity
