The number of multiples of 5 from 1 to 100 is:
1≤5n≤100
1/5≤n≤20, since n must be an integer
1≤n≤20
So the multiples of five number 20-1+1=20 elements, and the probability of choosing one of the multiples from the first 100 positive integers is:
P(5n)=20/100=1/5
Area of a circle is πr².
Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>
Surface area of a sphere is 4πr².
4<span>π(3.017)</span>² = 114.4 to 1DP
Answer:
the answer is 180 feet
Step-by-step explanation:
because it is a square all sides are equal so the distance is between two lines so you only have to add two sides: (90+90=180).
Answer:
12/40, 15/40, 18/40
Step-by-step explanation:
1/4, 1/2 = 1/4, 2/4
Since, Three rational numbers cannot come in between 1/4 and 2/4, we multiply them with 10.
∴ 1/4 × 10 = 10/40
∴ 2/4 × 10 = 20/40
∴ Three rational numbers between 10/40 and 20/40 = 12/40, 15/40, 18/40
(You can add more numbers from between 10/40 and 20/40 if you need)
Simply substitute x for -3 and y for -5, creating the equation shown below:
-6 (-3 - 2(-5) )
Now that you have your values set up, now you can do the math by starting off with Multiplying -2 by -5, which will get you 10.
Now that you have the parenthesis simplified in the parenthesis, you can use the distributive property by multiplying all the numbers with -6, like so:
-6(-3+10)= 18 - 60, which simplifies to -42, in which (A) is your answer.
