Martha has 103 and together Sandra and Martha have 170 coins.
10≤n<100
So the number of two digit numbers is 99-10+1=90
The only combinations that sum to 5 are 14, 23, 32, 41, 50 so
P(sum=5)=5/90
P(sum=5)=1/18
Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers (, , , , .)
- is equal to . In this expression, is the variable. Its exponent is , which isn't a natural number.
- On the other hand, is equivalent to . The exponent of variable is , which is indeed a natural number.
isn't a polynomial because the exponent of variable isn't a natural number. On the other hand, is indeed a polynomial over the set of real numbers.
The volume of the cylinder is 254,571.43cm³.
The surface area of the cylinder is 22,628.57 cm².
<h3>What is the volume of the cylinder?</h3>
A cylinder is a three-dimensional object. It is a prism with a circular base.
Volume of a cylinder =πr²h
- π = 22/7
- r = radius = diameter / 2 = 60/2 = 30cm
22/7 x (30²) x 90 = 254,571.43cm³
Surface area = 2πrh + 2πr²
(2 x 22/7 x 30 x 90) + (2 x 22/7 x 30²)
16, 971.43 + 5657.14 = 22,628.57 cm²
