Hey there! I'm happy to help!
Here's José's equation.
J=2a+15
And here is Nancy's.
N=3a+5
We want to find the number of animals where they are the same amount, or where J=N. We can write these equations as equal and solve for a to find the answer!
2a+15=3a+5
Subtract 15 from both sides.
2a=3a-10
Subtract 3a from both sides.
-a=-10
Divide both sides by -1.
a=10
Therefore, José and Nancy charge the same amount for 10 animals.
Have a wonderful day! :D
Here we are asked to find the smallest number which must be multiplied to 240 to make it a perfect square .
So , lets do prime factorisation of 240 .
Here , 240 = 2 × 120 .
= 2 × 2 × 60.
= 2 × 2 × 2 × 30.
= 2 × 2 × 2 × 2 × 3 × 5 .
Hence we got 240 = 2⁴ × 3¹ × 5¹ .
Now here we can see that , in order to make a perfect square it should be multiplied by 3 × 5 = 15 in order to make power of prime factors even .
Answer:
no they are not equal. In order to add radical expressions, the radicands must be equal.
So first u need to take a math torture
Since the new test score is 95 and that’s better than the previous max score, this new score will not impact the min value.
Since no one previously had scored that high, then the mode will also not change.
The range definitely changes, this is the new max value (so that changed), the mean will change with a new top score.
Since this is a new top score, the median will LIKELY change, but I think you could construct a situation where the median score doesn’t change. But that would be an unusual situation.
