Yes that is not correct , because -7 is lower than -15
Answer:
They are both equivalent just written in different ways
Step-by-step explanation
2 1/3
3*2=6
Add 1 which is the numerator
That leaves you with 7
Then you keep the 3 as the denominator.
That gives you 7/3
How to check
3 goes into 7, 2 times. So that gives you 2 and you have one left over to make it 7, so make 7 your numerator and the denominator always stays the same which is 3.
Hope this helps :3
Answer: 30 couples.
Justification:
You can follow a systematic approach to tackle this kind of problems.
Construct a chain of ratios whose units cancel out to yield to a result with the right units of the answer you are looking for.
In this case you want to know the number of couples that took the ride in 30 minutes.
The input data are:
1 couple / seat
1 seat / minute
Then, by multiplying those two data you get: [1 couple / seat] * [1 seat / minute], which, treating the units appropiately yields to 1 couple / minute.
Next, you realize that when you muliply 1 couple / minute times the number of minutes you get the number of couples that took the ride in that time.
So, the answer is: 1 couple / minute * 30 minute = 30 couples (the minutes cancel out because they appear in the denominator and numerator).
So, when you work with ratios and proportions, the use of units helps you a lot to figure out the way to get the answer.
Answer- 50.63
A= πr^2
A is 204 so 204= πr^2
Make are R the subject and the answer of the radius will be 8.06.
The equation for circumference is 2 πr and now we have R so just substitute it into the equation and the answer is 50.63
Answer:
3480
Step-by-step explanation:
Set it up so it looks like this.
(2580 + 2930 + x )/3 = 3000 Combine the terms on the left
(5510 + x) / 3 = 3000 Multiply by 3
5510 + x = 9000 Subtract 5510
x = 9000 - 5510
x = 3490
Does that really work?
2580 + 2930 + 3490 = 9000
Which says it does work.
