Answer:

3/12 is actually a quarter which is equal to 0.25.

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator,p, and a non-zero denominator q. For example, −3/7 is a rational number, as is every integer.

Yes it is...

Hope I got it right :P

Brian invests £4900 into his bank account.

True [87]

Answer:

£5200.68

Step-by-step explanation:

Given:

Investment P = £4900
Interest rate r = 1.5% or r = 0.015
Time t = 4 years
Number of compounds per year n = 1

Find the future amount:

$F = P*(1+r/n)^{nt}\\$
$F = 4900*(1+0.015/1)^{1*4}=4900*1.015^4 = 5200.68$

I need help with this question plzzz Geometry

KATRIN_1 [288]

Answer:

If the perimeter of a square measures 32 cm, each side measures 32/4= 8 cm, because all sides are equal.
The diagonal that passes through the center of the square divides the square into two triangles. The triangles are formed by a hypotenuse (the diagonal, which is k in this case), and two sides, that measure 8 cm each, in this case.
Because of Pythagoras' theorem, we know that the lenght of the hypotenuse (in this case the hypotenuse is k) equals the squared root of the sum of the squared sides, which in this case can be expressed as $k=\sqrt{8^2+8^2} =\sqrt{64+64}=\sqrt{128}=11.31$ .
Then, k=11.31 cm.
