Answer:

3.45×10^{5}

Step-by-step explanation:

The proper way to put a number in scientific notation is a specific way. So the answer you see above is the proper way you would put a number in scientific notation.

So. Put the decimal in between 3 and 4.

3.45000

Now count from the last 0 to 4. Which is 5. (Scientific notation can only be with 0's not any other number.)

So, it would be:

3.45×10^{5}

Hope this helped!

Answer:

3/5, 30%, 0.1

Step-by-step explanation:

0.4 + 1/2 + 40% = 0.4 + 0.5 + 0.4 = 1.3

3/4 + 0.25 + 1/2 = 0.75 + 0.25 + 0.5 = 1.5

3/5 + 30% + 0.1 = 0.6 + 0.3 + 0.1 = 1

The last choice is a probability complement because all values add to 1.

Vika [28.1K]

Answer:

2 meters

Step-by-step explanation:

Given

Volume = 4.5m^3

The question is incomplete as the picture of the tent is not attached.

However, I will use the attached figure to answer the question.

From the attachment, we have:

b = 1.5m --- base of the tent

l = 3m --- length of the tent

Required

Determine the height of the tent

The volume of the tent is:

\frac{1}{2} * bhl = Volume

Where h is the required height.

So, we have:

\frac{1}{2} * 1.5 * h * 3 = 4.5

\frac{1}{2} * 1.5 * 3 * h = 4.5

\frac{1}{2} * 4.5 * h = 4.5

Make h the subject

h = \frac{4.5 * 2}{4.5}

h = 2m

<em>The height of the tent is 2m</em>

Really hard geometry problems. Please help!
Bogdan [553]

Answer: For #3 the answer is 48 degrees, #4 is 70 degrees

Step-by-step explanation:

3. CGA and BGD are verticle angles which means they are congruent, and (2x-10)+(x+4)+(x+10) is 180. Which gives you X=44, then you substitute x into x+4 which gives you 48.

4. CEB and BED are supplementary which means they make up 180. BED and CEA are verticle angles which means they are congruent. We know CEB is 110 which means BED is 70 because 180-110=70. BED and CEA are verticle angles which means CEA is also 70 degrees
