PLEASE HELP ASAP 25 POINTS GOOD ANSWERS ONLY!

bob has 8 pieces of square index cards that each measures 8 inches per side. Using a pair of

scissors, he cuts each piece in half (so the resulting size is 8” x 4”) and then places all the

resulting card pieces in a new stack. If he repeats this procedure 4 more times, how many

pieces of card stock will he have and what will be the measure of each piece? (Note: All

cuts will be made along the longer edge of the piece if the piece of index card is not square.)

Answer:

The answer is 3. yes

The percentage difference in the amounts made is 30%.

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

Percentage difference= [ (amount made this year / amount made last year) - 1 ] x 100

'(650,000 / 500,000) - 1] x 100 = 30%

Answer:

Hi!!

The answer is = 0

Step-by-step explanation:

1. Distribute

3(2+4)=12

6+12=12

2. Subtract 12 from both sides of the equation

6 + 12= 12

6 + 12 − 12 = 12 − 12

3.Simplify

part A. 6 + 12 − 12 = 12 − 12

6x = 12 - 12

part B. 6x = 12 - 12

6x = 0

Answer:

2,616.67cm³

Step-by-step explanation:

Find the diagram attached

volume of the cone = πr²h/3

r is the radius = 10cm

h is the height = 25cm

Substitute

V = 3.14(10)²*25/3

V = 314*25/3

V = 7850/3

V = 2,616.67cm³

Hence the volume of the cone to the nearest hundredth is 2,616.67cm³

a. the sign is interchange

it should be = x^2 - 3x + 4 - x^3 - 7x + 2

Answer:

see explanation

Step-by-step explanation:

(a)

The student has distributed the second parenthesis by 1 instead of - 1

(b)

Given

(x² - 3x + 4) - (x³ + 7x - 2)

distribute the first parenthesis by 1 and the second by - 1, that is

= x² - 3x + 4 - x³ - 7x + 2 ← collect like terms

= - x³ + x² - 10x + 6

Answer:

105

Step-by-step explanation:

To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.

To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.

A = ([tex]\frac{14+38}{2}[/tex])(16)

A = 416 sqr centimeters

Answer:

Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.

Step-by-step explanation:

Subtract numbers:

−1−126 (−12−6+9−18)

−1−126 (−12−24+9)

Combine like terms:

−1−126 (−12−24+9)

−1−126 (−3−24)

Then you'll have to distribute:

−1−126 (−3−24)

−1+378 + 3024

Y = 1

Step-by-step explanation:

Proportional

Answer:

y=1

Step-by-step explanation:

Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.
