It looks difficult but it’s pretty easy. Just use the Ln function to bring down the powers then simplify.
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
(a/b) times (c/d)=(ac)/(bd)
16=16/1
(3/8) times (16/1)=(3 times 16)/(8 times 1)=48/8=(2/2)(2/2)(2/2)(6/1)=(1)(1)(1)(6)=6
answer is 6
Answer:
B.) x=5
Step-by-step explanation:
Use the Pythagorean theorem. Since it isosceles, both values of x are the same. Split 6 in half (because perpendicular bisector).Insert values:
X is equal to 5.
Done.
