(a) Consider the cube shown below. Identify the two-dimensional shape of the cross-section if the cube is sliced horizontally.
(b) Starting with the same cube, identify the two-dimensional shape of the cross-section if the cube is sliced vertically.
(c) Explain why the shapes are the same or different.
Answer:
a) square
b)square
c)they are the same thing because on all sides they are all the same length meaning the same shape
Step-by-step explanation:
If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
What is Three dimensional shape?A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
(a) If the cube is sliced horizontally, the cross-section will be a square.
(b) If the cube is sliced vertically, the cross-section will be a rectangle.
(c) The shapes are different because the direction of the slice is different. Slicing horizontally means the slice is perpendicular to the vertical edges of the cube, resulting in a square cross-section.
Slicing vertically means the slice is perpendicular to the horizontal edges of the cube, resulting in a rectangular cross-section.
The dimensions and orientation of the cross-section depend on the orientation of the slice relative to the edges of the cube.
Hence, If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.

10.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-2•(k-1)
———————— • k = 0 • k

Now, on the left hand side, the k cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-2 • (k-1) = 0
Equations which are never true:
10.2 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
10.3 Solve : k-1 = 0
Add 1 to both sides of the equation :
k = 1
Step-by-step explanation:
Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1
Equations and expressionsGiven the equation expressed as
5−k+12=16
We need to find the value of "k" that will make the equation equal
Given
5−k+12=16
Collect the like terms
17 - k = 16
Subtract 17 from both sides
17 - k - 17 = 16 - 17
k = 16 - 17
k = -1
Hence the value of k that will make the equation true is -1

Cinderella made many new friends at the castle. After asking her fairy godmother to help, she invited her friends to go on a picnic. There were 36 heads and 104 legs in the group of horses, carriages, and riders. How many horses and how many people were there?
Answer:
104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people
Answer:
26
Step-by-step explanation:
104/4=26

⦁ Calculate the area of the red triangle to find the area of the garden. Show your work. (2 points)
⦁ Millennium Park has an outdoor concert theater. Before a concert, the area reserved for special seating is roped off in the shape of a triangle as shown below. How can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape of a right triangle? (2 points)
⦁ The front of the stage, side C, is 50 feet long. A 40-foot rope runs along the side of square B. A 30-foot rope runs along the side of square A. Is the roped off area, triangle ABC, a right triangle? Explain. (2 points)
e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing.

Let's solve your equation step-by-step.
−x=2−3x+6
Step 1: Simplify both sides of the equation.
−x=2−3x+6
−x=2+−3x+6
−x=(−3x)+(2+6)(Combine Like Terms)
−x=−3x+8
−x=−3x+8
Step 2: Add 3x to both sides.
−x+3x=−3x+8+3x
2x=8

Elena is programming a video game. She needs to simulate the power-up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 and 100. Elena wants the best power-up to be rewarded 15% of the time. She could use the computer to simulate the player getting the best power-up at least 2 out of 3 times.
Which of the following matches the results to get the best power-up at least 2 out of 3 times.
1 Elena could have the computer generate 3 random integers between 1 and 100. If at least 1 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
2 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
3 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 30, then the player got the best power-up at least twice.
