Answer:
just keep writing down outcome on a sheet of paper then count total
Step-by-step explanation:
<u>Answer:</u>
The total number of whole cups that we can fit in the dispenser is 25
<u>Solution:</u>
It is given that the height of each cup is 20 cm.
But when we stack them one on top of the other, they only add a height of 0.8 to the stack.
The stack of cups has to be put in a dispenser of height 30 cm.
So we need o find out how many cups can fit in the dispenser.
Since the first cup is 20 cm high, the height cannot be reduced. So the space to fit in the remaining cups in the stack is only 30-20 cm as that’s the remaining space in the dispenser
So,
30 - 20 = 10 cm
To stack the other cups we have 10 cm of height remaining
As we know that addition of each adds 0.8 cm to the stack, the total number of cups that can be fit in the dispenser can be calculated by the following equation. Let the number of cups other than the first cup be denoted by ‘x’.
10 + 0.8x = 30
0.8x = 20
x = 25
The total number of cups that we can fit in dispenser is 25
Answer:
Step-by-step explanation:
You first want to get rid of the numbers which are in parenthesis
(-345(-23)
This is a multiplication between negative numbers
The law of signs in mathematics states that negative times negative equals positive
(-) (-) = +
(-345(-23)= 7935
Then we multiply the number which is outside of the parenthesis (4x)
(4x)7935= 31740x
Answer:
B
Step-by-step explanation:
All parallelograms have diagonals which bisect each other. This means the diagonals intersect and create equal lengths.
5y = 3x + 6
8x - 2 = 4x
Solve for x using 8x - 2 = 4x. Then substitute x into the other equation.
8x - 2 = 4x
-2 = -4x
1/2 = x
Substitute x = 1/2.
5y = 3(1/2) + 6
5y = 3/2 + 6
5y = 3/2 + 12/2
5y = 15/2
y = 15/10
y = 3/2 or 1.5
