Which of the following equations is true?
A.
(2 × 3) + (-2 × 3) = (-2 × 2) + (3 × 3)
B.
(2 ÷ 3) ÷ (3 ÷ -2) = (-2 ÷ 2) ÷ (3 ÷ 3)
C.
(-2 - 3) - (3 - 2) = (-2 - 2) - (3 - 3)
D.
(-2 × 3) × (2 × 3) = ( 3 × 2) × (3 × -2 )
Answer:
D
Step-by-step explanation:
A: (2 × 3) + (-2 × 3)= 0
(-2 × 2) + (3 × 3) = 5
B:(2 ÷ 3) ÷ (3 ÷ -2) = -0.44444444444
(-2 ÷ 2) ÷ (3 ÷ 3)= -1
C:(-2 - 3) - (3 - 2)=-6
(-2 - 2) - (3 - 3)=-4
D:(-2 × 3) × (2 × 3)=-36
( 3 × 2) × (3 × -2 )-36

if a person takes a jump which is half a feet and then gets tired so he takes another jump which is half if the first jump and he takes another jump which is half of the second jump and so on how many jumps will it take the person to reach the distance of 1 foot
NOTE:=NO NONSENSE ANSWERS OR YOU WILL GET REPORTED
if there are any doubts about this question you can comment them down below and please read the question carefully
ANSWER ONLY IF YOU ARE SHURE
he will never reach 1 foot
A box is to be made where the material for the sides and the lid cost $0.20 per square foot and the cost for the bottom is $0.05 per square foot. Find the dimensions of a box with volume 20 cubic feet that has minimum cost.
Please answer in length , width and height in ft
Answer:
Let x represent the edge dimension of the square base in feet. Then the area of the base or lid is x², and the height of the box is 5/x². Total cost is then ...
... cost = cost of lid + 4×(cost of one side) + cost of bottom
... cost = 0.2x² + 4×(0.2x(5/x²)) + 0.5x²
... cost = 0.7x² + 4/x
We can differentiate this with respect to x and set that derivative to zero. This will give us the x-value at which the cost is a minimum.
... d(cost)/dx = 1.4x -4/x² = 0
... x³ = 4/1.4
... x = ∛(20/7) ≈ 1.419
Then the height of the box is
... height = 5/x² ≈ 5/2.01351 ≈ 2.483
The box is 1.491 ft square and 2.483 ft high.
______
The average cost of the top and bottom is (0.2 +0.5)/2 = 0.35 per square foot. The overall cost will be minimized when the average cost of each face is the same. That is, the areas of the lateral faces will be equal and must be 0.35/0.2 = 1.75 times the area of the top or bottom to make the average cost of a lateral face equal to that of the top or bottom. Hence, the base will be square, and the box will be 1.75 times as high as it is wide or deep. The base edge dimension is then ∛(5/1.75) ≈ 1.419 ft.

If the height of the box is 7 inches, what is the volume of the box?
Answer:
The volume of this shape is 41 inches sq. :)
Step-by-step explanation:
7 x 3 = 21
2 x 2 = 4/2 = 2
2 x 2 = 4/2 = 2
2 x 2 = 4/2 = 2
2 x 2 = 4/2 = 2
2 x 3 = 6
2 x 3 = 6
21 + 2 + 2 + 2 + 2 + 6 + 6 = 41

Letter C, E, and F: 2 8/10, 2.8, and 28/10
Step-by-step explanation: The shaded pillars/rectangles inside the squares account for the fractions. In this question, there are 10 pillars per square and 2 shaded in squares. Since there are two full squares, there are two wholes. In the third block, there are only 8 shaded. Because 8 out of ten are shaded, the fraction would be 8/10 (said as eight tenths). Overall, there are two wholes (the shaded squares) and 8/10 of a whole. Therefore, it is 2 8/10. 0.8 equals 8/10 (you can determine it by the way it is said ex: you would say “zero and ...” (and = decimal) “... eight tenths” or just “eight tenths” for .8, and 8/10 is said the same way). Since 2.8 and 2 8/10 are equal, 2.8 would also be an answer. 28/10 would be another correct answer because the two wholes/squares each have 10 pillars. In total, there are 20 pillars for the two wholes. If the 8/10 (8 out of 10) is added, the total would be 28/10. Hope this helps!

Answer:
30 books on the shelf are Fiction.
Step-by-step explanation:
Hey!
There are 50 books on a shelf.
1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.how many books on the shelf are Fiction?
==================================================================
MAKE AN EQUATION!
We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.
Total- 50
⇒ 50 =
1/5 of 50 are SF
⇒ 50 = (1/5)(50)
3/10 of 50 are NF
⇒ 50 = (1/5)(50) + (3/10)(50) + x
--------------------------------------------------------------------------------------------------------------
SOLVE THE EQUATION!
(1/5)(50) + (3/10)(50) + x = 50
To Isolate X-
-Multiply and remove the parentheses..
⇒ 50/10 + 150/10 + x = 50
-Simplify.
⇒ 5 + 15 + x = 50
-Add Like Terms
⇒ 20 + x = 50
-Subtract 20 from both sides.
⇒ 20 + x - 20 = 50 - 20
-Simplify Right Hand Side.
⇒ x = 30
--------------------------------------------------------------------------------------------------------------
So, 30 books on the shelf are Fiction.
==================================================================
Hope I Helped, Feel free to ask any questions to clarify :)
Have a great day!

The bowling alley charges $75.00 to reserve the location, and then $8.00 per person. Which expression represents the total cost for any number of people n?
Answer:
75+8n
Step-by-step explanation:
$75 is the constant because that is the amount of money only paid once. $8 is the coefficient because it is multipled by the variable n. The variable is the amount of people going to the bowling alley.
Therefore, to determine the total cost, you need add $75 to the product of 8 and the number of people coming.

Dani experimented with a dollar bill and the copy machine a dollar bills length is 6.1 inches and width is 2.6 inches, she reduced the dollar bill so its length was 80% of its original size. What is the length of the copy of the dollar bill? please show how you figured it out. NO LINKS
Answer:
The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.
Step-by-step explanation:
If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.
80% = 0.8
0.8 x 6.1 = 4.88
80% = 0.8
0.8 x 2.6 = 2.08
