Answer:

To find the volume you have to multiply all the number together in any order. The order doesn't matter.

Step-by-step explanation:

To find volume=

40*20= 800

then, 800*60= 48,000

since it's in cm and there are 3 numbers then it would be 48,000 cm cubed

What is the value of x in the equation below? 1+2eX+1 = 9

Monica [59]

The value of x is 1.252762968495368

Solution:

Given that,

We have to find the value of x in given equation

Given equation is:

$1+2e^x + 1 = 9$

Simplify the left side of equation

$2+2e^x = 9$

Move 2 from left side to right side of equation

$2e^x = 9-2\\\\2e^x= 7$

Therefore,

$e^x = \frac{7}{2}\\\\e^x = 3.5$

Taking ln on both sides

ln and e cancels each other each other

$x = ln\ 3.5$

Therefore,

x = 1.252762968495368

Thus the value of x is found

Reduce To Simplest Form. 2/2 + 1.75 - 44/25 =

Soloha48 [4]

Answer/Step-by-step explanation:

First, we should make each fraction, decimal, whole number into fraction and number form.

So, 2/2 = 1.

1.75 is 1 3/4.

44/25 is 1 19/25.

Now we have our equation, now we can do this equation easier.

1 + 1 3/4 - 1 19/25.

1 + 1 3/4 = 2 3/4.

Then, we turn both numbers to Decimal Form.

2 3/4 = 2.75

1 19/25 = 1.76.

When we divide 19 by 25, we get 0.76.

Then we subtract the decimals.

We should start right and end left.

5 - 6 = -1, we need to borrow one from the closest digit to the left, which is 7. Now we have 15 - 6 = 9.

Next, we have 6 - 7 = -1, we need to borrow one from the closest digit to the left, which is 2. Now we have 16 - 7 = 9.

Our answer right now is 0.99.

Lastly, 1 - 1 = 0.

Which leaves us with the answer: 0.99 (Zero and Ninety Nine Hundredths.)

Best of Luck to you.
