Answer:T=1.54yr
Step-by-step explanation:
Formulate for simple interest
I=prt/100
T=100I/pr
T=100×400×12/30100×10
T=1.54yr

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)
(x-4)/2(x+4)
Answer:
13.) 0.19625 15.) 37.68
Step-by-step explanation:
Formula for area of a circle: A=πr²
13.) 3.14 x .25² = 0.19625
Formula for circumference for a circle: C=πD or C=2πr
15.) (6 x 2) x 3.14 = 37.68
Hope this helped : )
