Simplify (9s/2t)* (2s/3)

Answer:

3s^2/t

Step-by-step explanation:

(9s/2t)* (2s/3)

Multiply the numerators

9s*2s = 18s^2

Multiply the denominators

2t*3 = 6t

Put the numerator over the denominator

18s^2/6t

Divide the top and bottom by 6

3s^2/t

Answer:

You'd get 18s^2/6t by simply multiplying. To simplify just decide each sides by 6 and you'd get 3s^2/t

What is the unit rate of 600 calories / 1.5 h

Well, a unit rate usually has a denominator of 1 so...

Divide 600 calories by 1.5 h (600 ÷ 1.5) to get 400 calories/ 1 h

So the unit rate is 400 calories per h (not sure what 'h' stands for..)

Divide 600 calories by 1.5 h (600 ÷ 1.5) to get 400 calories/ 1 h

So the unit rate is 400 calories per h (not sure what 'h' stands for..)

Fran solved the equation 42 = x + 23 . Although her final answer was correct, she could have found it in a simpler way. Which sentence best explains why?

The simpler way of solving the equation given is two just subtract 23 from both sides.

What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.

For examples, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given that, a solution of Fran of solving an equation 42 = x + 23, she opted for a long process, we need to tell which could be a simpler way to solve this,

So, the equation is 42 = x + 23

If we subtract 23 from both sides, we can simply get the answer,

So,

42-23 = x + 23 -23

x = 19

Hence, the simpler way of solving the equation given is two just subtract 23 from both sides.

He just have to do a substraction.

42 = x +23

42 - 23 = x

19 = x

x= 19

That's simple !

Hope this helps !

How do you find the average rate of change in calculus?

The average rate of change doesn't require calculus.

It's just

(amount of change during some time) / (amount of time for the change) .

You need calculus when you want the instantaneous rate of change . . .

that's the rate of change at a single point in time.

Grandma bakes the world's best and favorite cookies. If grandma's cookies have a half life of 2 hours and she bakes 3 dozen cookies, how many hours will pass until only two cookies remain? a. 56 minutes

b. 1 hour and 17 minutes

c. 1 hour and 10 minutes

d. 8 hours and 20 minutes

Answer:

The time that pass until only two cookies left is 1.89 hour

Step-by-step explanation:

Given as :

The number of cookies bakes in 2 hours = 3 dozen

∵ 1 dozen = 12 piece

So, In 3 dozen = 12 × 3 = 36 cookies

The Time required to bake 36 cookies = 2 hours

Now, Let The time required to bake 2 cookies = x hour

So, According to question

∵ The time required to bake 36 cookies = 2 hours

So, the time required to bake 1 cookies = = hour

∴The time required to bake 34 cookies = × 34

I.e The time required to bake 34 cookies = hour = 1.89 hour

Or, the time taken is 1.89 hours

Hence The time that pass until only two cookies left is 1.89 hour Answer
