Solve for G
9+3.5g=11-0.5g
G=_______

Answers

Answer:

g = 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9+3.5g=11−0.5g

9+3.5g=11+−0.5g

3.5g+9=−0.5g+11

Step 2: Add 0.5g to both sides.

3.5g+9+0.5g=−0.5g+11+0.5g

4g+9=11

Step 3: Subtract 9 from both sides.

4g+9−9=11−9

4g=2

Step 4: Divide both sides by 4.

Amanda makes 3 biscuits in 2 minutes. How many biscuits can she make in 30 minutes?

Answers

45 because 30 divided by 2 is 15 the 15 times 3

Amanda makes 45 biscuits in 30 minutes which is determined by the ratio.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that Amanda makes 3 biscuits in 2 minutes.

Let the number of biscuits would be x

To determine the number of biscuits can she make in 30 minutes.

According to the given question, we can write the ratio as:

3 biscuits : 2 minutes = x biscuits : 30 minutes

⇒ 3 / 2 = x / 30

Apply the cross-multiplication operation

⇒ x = (30 × 3) / 2

Apply the multiplication operation

⇒ x = 90 / 2

Apply the division operation,

⇒ x = 45

Therefore, she makes 45 biscuits in 30 minutes.

A large community college has professors and lecturers. The total number of faculty members is 136. The school reported that they have 6 professors for every 11 lecturers. How many professors does the community college employ?

Answers

answer : 125
explain: none

Answer:

48 professors

Step-by-step explanation:

First, add 11 + 6 = 17

Here is what I did after that,

136 / 17 = 8

I divided 136 by 17 because for every 11 lecturers there are 6 professors, and to get the total amount of how many times there are 6 professors and 11 lecturers.

After that, you would multiply 8 * 6, since there are 6 professors.

So, the answer that I got would be 48.

What is a set theory?

The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.

Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,

U = {1, 2, 3, 4, 5

A =  {1,5}

A' = {2,3,4}

Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Step-by-step explanation:

Simplify the expression.

Answer:

-13.11

Step-by-step explanation:

Remember: Please Excuse My Dear Aunt Sally (PEMDAS)

You use the parentheses first, so it is 18.03-3*(20.76)÷2

So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14

Then, you subtract from left to right, which gives you: -13.11
