Answer:
a) 2.5π, b) ≈673 times
Step-by-step explanation:
diameter = 2.5
circumference = diameter*π
circumference = 2.5π
5280/2.5π
≈5280/2.5*3.14
≈5280/7.85
≈672.6, ≈673
Answer:
The answer to your question is 900 black and white copies
Step-by-step explanation:
Data
9 black and white copies for every 2 colored
printed 200 color copies
black and white copies = ?
Process
This is a proportion exercise
BW : C :: bw : c
9 : 2 :: bw : 200
bw = 200(9) / 2
bw = 1800 / 2
bw = 900 copies
Answer:
Step-by-step explanation:
v(5v-7)=0
We multiply parentheses
5v^2-7v=0
a = 5; b = -7; c = 0;
Δ = b2-4ac
Δ = -72-4·5·0
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
v1 = −b−√Δ/2a
v2 = -b+√Δ/2a
√Δ = √49 = 7
v1 = -(−7)−7/2*5 = 0/10 = 0
v2 = -(−7)+7/2*5 = 14/10 = 1+2/5
