Answer:
75 is between 64 and 81.
Step-by-step explanation:
The number 75 falls between 64 and 81, which are both perfect squares.
To find out whether a number is a perfect square, we can take the square root of said number. If the answer is a whole number, then the number is a perfect square.
The square root of 64 is 8 and the square root of 81 is 9, so they are both perfect squares. We know that 75 is between the numbers 64 and 81, therefore our answer is correct.

Answer:
60%
Step-by-step explanation:
2/5 to 100%
we have to make the bottom number equal 100
5*20=100
what we do to one side we have to do to the other when multiplying and dividing fractions
2*20=40
40/100
we're looking for the OTHER vegetables so subtract that from the total
100/100 - 40/100 =60/100 or 60%

Answer:ill help all triangles should equal to 180 hope it did help you
Step-by-step explanation:
To evaluate the <span>probability that in a randomly selected hour the number of watches produced is greater than 500 we proceed as follows:
z=(x-</span>μ<span>)/</span>σ
where:
x=500
μ=500
σ=100
thus
z=(500-500)/200=0
Thus:
P(x>500)=1-P(x<500)=1-P(z<0)=1-0.5=0.5
Answer: 0.5~50%
