30% of a number is 90. what is 1% of the number? a) 3 b) 30 c) 60 d) 27

A) 3

Reasoning: 30% of a number is 90, to find this divide 90 by .30

90/.30=300

So 30% of 300 is 90

Now 1% of 300

300 x .01=3

So the answer is 3

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
