Answer:

1,820 trout

Step-by-step explanation:

Set up a proportion where x is the number of trout in the lake:

$\frac{7}{25}$ = $\frac{x}{6,500}$

Cross multiply and solve for x:

25x = 45,500

x = 1820

So, you could expect 1,820 trout to be in the lake.

What is 62% of 25 ?<br> im horrible at this plz help

hodyreva [135]

62% of 25

'of' means multiplication.

$\sf 62\%\times 25$

Convert 62% to a decimal, divide it by 100(since percentages are parts of 100):

62/100 = 0.62

$\sf 0.62\times 25$

Multiply:

$\sf\boxed{\sf 15.5}$

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 2323 Pennies 55 Dimes 2020 Nic

GaryK [48]

Answer:

The answer is "0.081"

Step-by-step explanation:

Dimes $= 55$

Calculating total coins $= (23+55+20+19) = 117$

P(for a dime) $= \frac{55}{117}$

Calculating remaining coins $= 116$

Nickels $= 20$

P(for nickel draw in second) $= \frac{20}{116}$

P(for a dime after that a nickel, without replacement)

$= \frac{55}{117} \times \frac{20}{116} \\\\= \frac{1100}{13572} \\\\=0.081$

their was only 1/2 pizza 3 needed 2 share it ... how much of the original pizza woud each person get please help right away!!!!!

denpristay [2]

We are going to have to divide...
We have to put 1 as a denominator for 3 because it's a whole.
$\frac{1}{2} / \frac{3}{1}$
Cross multiply.
$1*1=1$
$3*2=6$
$= \frac{1}{6}$
Each person would get $\frac{1}{6}$ of the original pizza.

Have a nice day! :)
