I'm guessing the question is meant to be "<span>If the radius of a circle with a area of 5.3 mm squared is multiplied by 5, what will the new area be?", so i'll answer that.
Area of a circle =</span>πr^2
5.3=πr^2, 5.3=π(5r)^2
132.5=25πr^2
Answer:
Order of Operations.
Step-by-step explanation:
If we include -7 in the parenthesis, the exponent acts the negative as well. Therefore:
(-7)²= 49.
However, when squaring without the parenthesis, it will give us a negative number because:
The order of operations, or PEMDAS, states that exponents come before multiplication. Therefore, when doing '-7²', you would first need to square the '7', giving us:
-7² = -49
However, within parenthesis, everything inside will be squared.
9514 1404 393
Answer:
9
Step-by-step explanation:
The prime factorization of 945 is ...
945 = 3³·5·7
suggesting the numbers are 3, 5, 7, 9. These have a sum of 24.
The largest of the integers is 9.
First, you’re gonna find your rate of change for minutes per mile by dividing the minutes by the miles (25/3.5), which equals about 7.14 minutes (but if you don’t round, it’s 7.14285714 minutes) and then you’ll multiply this by 7 miles (7.14285714*7) and get 50 minutes for 7 miles.
Answer:
The probability of getting exactly 3 head=0.3125
Step-by-step explanation:
Given that probability of getting head p=0.5
So probability of getting tail q=0.5
Number of coin toss n=6
And number of trial r=3
We know that from Binomial distribution function,the probability given as follows
So now by putting the values
Now by solving this
The probability of getting exactly 3 head=0.3125
