Answer:
a. 146
Step-by-step explanation:
{4*[72-6*(3+2)]}-22
=[4*(72-6*5)]-22
=[4*(72-30)]-22
=(4*42)-22
=168-22
=146
Answer: Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.

From the given figure it is clear that
The scale factor of a figure is
The scale factor is 1/3 because CB is actually 2 + 4 = 6.
Therefore the correct option is D.
Answer: Choice B) 3 years

Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
