Which number is the greatest?
A the square root of 125
B the whats root of 30

Answers

Answer:

B) √(30)

Step-by-step explanation:

A: The cube root of 125 is 5 because 5^3, or 5 × 5 × 5, equals 125.

B: The square root of 30 is between the numbers 5 and 6, meaning 30 is between 25 and 36. The square root of 30 is about half-way in between 5 and 6, so we can say √(3) ≈ 5.5

Now, when we compared 5.5 and 5, 5.5 is obviously greater. Therefore, the correct answer is B √(30).

Answers

Answer:

20. A. y= 10x = 15

21. C. Php 75.00

22. B. Php 195.00

Step-by-step explanation:

She has to pay 25 Pesos for one hour and only ten more each hour after that. That can be represented in the formula Y= 10x +15. To solve the rest of the questions, just substitute 6 hours for question 21 and 18 hours for question 22.

Answers

A, y= 10x + 15

C, 75.00

B, 195.00

Explanation for the first question:

We can see in the table the price is going up by 10

25 to 35 to 45, etc

So 10x + 15

Explanation for question 2:

We know the equation is 10x + 15. X is the amount of hours so that is our 6. If you plug it into the equation you get

10(6) + 15

Multiply first

60+15

Then add

You get 75.

Explanation for question 3:

Do the same as question 2 just with 18 instead of 6.

10(18) + 15

Multiply

180 + 15

Add

Answers

Answer:

63.90 divided by 2 is 31.95

31.95-17.95=14

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 6400 kilograms have already been loaded into the container.

Answer:

[tex]x<=118[/tex]

Step-by-step explanation:

We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].

So, the inequality is [tex]150x+10300<=28000[/tex].

We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].

We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].

So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!

10: Option 1. He gains more money this way.

In option 1 if he gets his allowence for 4 weeks, he would make $15 (1+2+4+8).

But in option 2 he would only make $4 because the square of 1 is 1 (1+1+1+1)

Hope that helps and hope I did that correctly

#9

Total amount = $525

Split by a fraction, divide by 5 and then again divide by 5:

525*1/5*1/5 = 525*1/25 = 21a) The fraction = 1/25b) The amount = $21#10

Option 1 results in sequence:

1, 1*2=2, 2*2=4, 4*2=8, etc

Option 2 results in sequence:

1, 1² = 1, 1² = 1, 1² = 1, etc.

It's obvious that option 1 is a better choice.

x+x refers to x being multiplied

For Eg:

You are selling flowers for a fundraiser . You pay $ 1.50 for each flower plus a flot rate delivery fee of $ 15 . You are selling the flowers for $ 3 . At least how many flowers do you need to sell to make a profit ?​

Answers

Answer:

15÷1 .50=10

Because you are already paying a flat rate of $15. You make 1.50 off of each flower. So you have to sell over 10 flowers to make a profit.

At least 11 flowers should be sold to make a profit.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

Given:

Total cost for the buying flower = 1.5 * number flowers  + 15

For n=10                                       = 1.5 * 10 + 15

                                                     = 30

By selling 10 flowers                    =10 * 3

                                                     = $30

For n =11                                        = 1.5 * 11 + 15

                                                      = 31.5

By selling 11 flowers                    = 11 * 3

                                                     = 33

Therefore, At least 11 flowers should be sold to make a profit.
