Step-by-step explanation:

A = P( 1+r/n)^nt

= 462446.95 (1+.084/4)^4x20

= 2,438,491.73

On Monday, Nalim made a journey.
xenn [34]

Answer:

Step-by-step explanation:

Let's put in some numbers to make this easier to understand.

Let's say she has to travel 20 km.

On Monday, she travels at 4 kph.  This takes 5 hours.

On Tuesday she travels 25% faster, at 5 kph.  This takes 4 hours.  

To figure percent reduction we take

100 % * (old - new) / old  

100 % * (5 hr - 4 hr ) / 5 hr

100 % * 1 hr / 5 hr

100 % * 0.20

20% reduction.

In a basket, there are 7 male kittens and 5 female kittens. Donna randomly selects one, puts it back, and then randomly selects
andre [41]

We are given that

number of male kittens =7

number of female kittens =5

total number of kittens = number of male kittens + number of female kittens

total number of kittens = 7+5

total number of kittens = 12

now, we can find probability of selecting female kittens

P(female kittens)=(number of female kittens)/( total number of kittens)

P(female kittens) is

=\frac{5}{12}

now, we are given that

Donna randomly selects one, puts it back, and then randomly selects another

so, both probability are independent

so,

the probability that both selections were female kittens is

=P(female kittens)*P(female kittens)

now, we can plug values

the probability that both selections were female kittens is

=\frac{5}{12}\times \frac{5}{12}

=\frac{25}{144}...............Answer

mihalych1998 [28]
Your answer would be C

(√2)(∛2)

(\sqrt[6]{2^3})(\sqrt[6]{2^2})

\sqrt[6]{2^5} = \sqrt[6]{32}

If you do 2^5/6

\sqrt[6]{2^5} = \sqrt[6]{32}
