Say you are trying to write a very big number, how about 13 s extillion

Now, we could write this number like this

13,000,000,000,000,000,000,000 in standard notation

Or, we could write it like this

1.3 x 10^22, in scientific notation, which is vastly easier to deal with.

A chef at a restaurant uses 14 pounds of butter each day. About how many grams of butter does the chef use each day Start Fract

olganol [36]

Answer:

6361.6 grams

Step-by-step explanation:

A chef at a restaurant uses 14 pounds of butter each day

Given;

16 ounces per pound

And

28.4 grams per ounces

Converting 14 pounds to gram;

14 pounds × 16 ounces/pound = 224 ounces

Then;

224 ounces × 28.4 grams/ounce = 6361.6 grams

Write a word description of the set.

pychu [463]

Answer: negative integers greater than -10

This is because stuff on the number line to the right is larger than stuff on the left. We can say 2 < 7 since 7 is to the right of 2.

Also, -7 < -2 for similar reasoning.

Saying integers greater than -10 excludes this endpoint. We stop once we reach -1 because 0 and anything larger aren't negative integers.

Answer:

m = 1/3

Step-by-step explanation:

<u>Step 1</u>. Pick a line of the table to use as (x1, y1).

<u>Step 2</u>. Pick a different line of the table to use as (x2, y2).

<u>Step 3</u>. Use the slope formula:

m = (y2 -y1)/(x2 -x1)

<u>Step 4</u>. Simplify the result.

Here are these steps for this problem.

1, 2. use (x1, y1) = (-9, -5) and (x2, y2) = (-3, -3)

3. m = (-3 -(-5))/(-3 -(-9)) = 2/6

4. m = 1/3

I need help with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x

Leona [35]

<h3>Answer: x = 25</h3>

Explanation:

The rule is that for any triangle, the three angles always add to 180 degrees

So A+B+C = 180

Replace A with 65, replace B with 3x-10 and replace C with 2x to get this new updated equation: 65 + 3x-10 + 2x = 180

Now let's isolate x

65 + 3x - 10 + 2x = 180

5x + 55 = 180 .................... combine like terms

5x + 55 - 55 = 180 - 55 ..... subtract 55 from both sides

5x = 125

5x/5 = 125/5 ..................... divide both sides by 5

x = 25

We can stop here since your teacher only wants to know the value of x.

-----------

If you're curious how to find the other angles, then replace x with 25 and compute

Angle B = 3x - 10 = 3*25 - 10 = 75 - 10 = 65 degrees

Angle C = 2*x = 2*25 = 50 degrees

Therefore, the three angles of the triangle are A = 65, B = 65, C = 50. As a check, they should add to 180. It turns out they do since A+B+C = 65+65+50 = 130 + 50 = 180. Therefore, the answer is confirmed.

note: since angles A and B are both the same at 65 degrees, this means the triangle is isosceles (the sides opposite the congruent angles are congruent sides). We do not have enough info to actually find the length of any of the three sides.
