Hey! Elizabeth here! I would say the answer to your current question is Planet A. or C. The Planet A. has all of the Earth Requirement(at least I thinks..), same with Planet C! But if your question only require 1 answer, then I'll choose Planet C, since it have H2O for us, without the H2O, then how will we survive?

I hope this helped you out a little! Good Luck with your assignment & have a wonderful day! ^^

Two angles are vertical angles. The measure of one angle is (3x) degrees. The measure of the other angle is 42 degrees. What is the value of x?

Answers

Answer:

x =14

Step-by-step explanation:

Vertical angles are equal.

This means that 3x = 42

Divide each side by 3

3x/3 = 42/3

x =14

Answer: x=46.

Step-by-step explanation:

Vertical angles are opposite of one another. A whole line is 180 degrees. You have to subtract 42 from 180 which gives you 138. Then you divide by 3. Then you get 46.

Answers

Answer: i would say 1/3.

Step-by-step explanation:

.......

Answer:

b. 2/3

Step-by-step explanation:

First, I multiplied all of the values to each other, to get the area^3 of the box.

With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed.

a-4.73925/1/3=12.21775

b-4.73925/2/3=7.108875

c-4.73925/1/2=9.4785

d-4.73925/1=4.73925

I didnt use the full answer from when I multiplied all the answers together, so the answer will be just hardly off a whole number. So, b should be the answer.

If the answers were side lengths, read below

First, I multiplied all of the values to eachother, to get the area^3 of the box.

With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed, after I cubed them.

a-1/3^3=1/27

b-2/3^3=8/27

c-1/2^3=1/8

d-1^3=1

Next, I divided 4.73925 by all of the values listed above.

a-4.73925/1/27=127.9595

b-4.73925/8/27=15.9949

c-4.73925/1/8=37.914

d-4.73925/1=4.73925

After I had completed this process, b is still the closest to a whole number, So, b is my answer.

If a widget factory as a fixed operating cost of $2,500 per day plus a cost of $1.50 per widget produced. If a widget sells fro $5.00, what is the least number of widgets that must be sold per day to make a profit?

Answers

Answer:

At least 714 numbers of widgets must be sold per day to make a profit.

Given fixed operating cost = $2,500 per day cost of widget =$ 1.50

widget sells  =$ 5.00

Cost function = C(X)=1.50x+2500

Revenue function = R(X)=5 x

At Break Even point R (X) = C (X)5

X= 1.50X+2003.5

X =2500X =714

Hence to reach break even point or make profit 714 no to be sold. R(714)= 3571.

Im assuming that you mean a to the power of negative to 2 with a being 6. 6 to the power of negative 2 is 0.027777 repeating, so it can't be -36 or -12. 6^2 is 36 so it can't be that either. 1/6^2 is 0.02777777 repeating so that is the answer. Ur welcome :)

connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?

Answers

Answer:

96

Step-by-step explanation:

Step 1: Multiply 60% by 40

40 x .60 = 24

24 is 60 percent of 40

Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.

100 ÷ 25 = 4

Step 3: Multiply 4 by 24

4 x 24 = 96

Lara is x years old and her two best friends are (x-2) and (x+2). Write an expression for the square of Lara’s age and the product of ages of Lara’s best friends.

Please help with a detailed step by step thanks

Answers

Answer: x^2 + (x+2)(x-2)

Step-by-step explanation:

The caret ^ before the 2 indicates that the 2 is an exponent. It means "x squared"

If the keyboard doesn't allow exponents the caret is the thing to use.

The expression for the square of Lara’s age and the product of ages of Lara’s best friends is x² + (x-2)(x+2)

The first thing to do is to calculate the square of Lara's age and this will be:

= x × x = x²

The product of the ages of Lara’s best friends will be (x-2)(x+2).

Therefore, the expression that can be used to calculate the square of Lara’s age and the product of ages of Lara’s best friends is x² + (x-2)(x+2)

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)


Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000


Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.


Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12


Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.
