(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.

Answers

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.

Which values for A and B will create infinitely many solutions for this system of equations?

Answers

Answer:

A = -6; B = 15

Step-by-step explanation:

4x-Ay=15

-4x+6y=B

This is your system of equations. For it to have infinitely many solutions, the lines have to be the same. This means that if you multiply one equation by a constant, you should be able to get the other one.

With this system, you have 4x in one equation and -4x in the other. You can use this to figure out the constant. Because -4 is, well negative four, you know that the second equation is the opposite of the first; everything is multiplied by -1.

That means A = -6 and 15 = -B (The other coefficients and constants of the equations also have to be opposites.), and you can solve for B now. Divide by -1 to get B=15.

Zoey goes to a store an buys an item that costs x dollars. She has a coupon for 15% off, and then a 9% tax is added to the discounted price. Write an expression in terms of x that represents the total amount that Zoey paid at the register.

Answers

Answer:

0.9265x

Step-by-step explanation:

x - 0.15x + 0.09(0.85x)

x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.

Simplified:

x - 0.15x + 0.09(0.85x)

= 0.85x + 0.0765x

= 0.9265x

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.

Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Answers

Answer:

y = 21

x = 8

Step-by-step explanation:

AB = 180

27 + 3y = 90°

-27 -27

-----------------------

3y = 63

÷3 ÷3

--------------

y = 21

x + 27 + 3y + 8x + 18 = 180

9x + 45 + 3(21) = 180

9x + 45 + 63 = 180

9x + 108 = 180

-108 -108

-----------------------

9x = 72

÷9 ÷9

----------------

x = 8

I hope this helps!

Y = 21
X = 8

We can figure out Y by finding the right angle. A right angle is 90 degrees so we start out with:
90-27
Then,

Do the same for X to get 8

Step-by-step explanation:

Because you take the total value, multiply it by the rate of the discounted value and subtract that number from the total. Then you want to find the total amount with tax after the discount, so you would multiply the total you got before by the amount of tax, then add that amount to that number and that would be your answer with the discount and tax! (When multiplying a percentage, you move over the decimal 2 places to the left. So, with a 25% discount, you would multiply the total by .25 and then subtract that number from the total price!)

The third one. I’ve shown my work below. The first two are positive and the last one is 0, which is neither positive nor negative

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.
So the answer is the third one
