Answer:
Step-by-step explanation:
since the cross multiples are equal, you find a product and use the inverse operation as you would in an equation
Example 4 is to 36 as 3 is to X: 4/36 = 3/X --> 4*X = 3*36. Divide both sides by 4, to solve for X = 27.
is over of = percent of 100
is/of=%/100
What is 10% of 40.
is = x
x/40 = 10/100
cross mulitply 40*10= 400/100=4 x=4

Answer:
A sequence is a function whose domain is the set of natural numbers.
Step-by-step explanation:
To determine the area of of the thin circular body given the diameter, use the equation, A = πd²/4.
Substituting the given diameter to the equation,
A = π(3²) / 4 = 9π/4
Thus, the area of the sand dollar is approximately 7.07 in².
(a) 9
(b) number of pens = 171/9 = 19
number of pencils = 63/9 = 7
number of erasers = 27/9 = 3
