The combined weight of 2 identical dice, 5 identical balls and 4 identical marbles was 260 grams. The combined weight of one die

olya-2409 [2.1K]

Answer:

The total weight of one die, one ball, and one marble is 75 grams.

Step-by-step explanation:

Consider the provided information.

Let d represents the number of dice, b represents the number of balls and m represents the number of marbles.

So according to the question.

The combined weight of 2 identical dice, 5 identical balls and 4 identical marbles was 260 grams.

$2d+5b+4m=260$ ....(1)

The combined weight of one die and one marble was 55 grams.

$d+m=55$

$m=55-d$ ....(2)

3 balls weighed the same as two dice.

$3b=2d$

Multiply both sides by 5 and divide by 3.

$5b=\frac{10}{3}d$ .....(3)

Now put the value of equation 2 and 3 in equation 1.

$2d+\frac{10}{3}d+4(55-d)=260$

$2d+\frac{10}{3}d+220-4d=260$

$\frac{6d+10d-12d}{3}=40$

$4d=120$

$d=30$

Put d=30 in equation 2.

$m=55-30$

$m=25$

Put d=30 in equation 3.

$5b=\frac{10}{3}\times 30$

$5b=100$

$b=20$

The total weight (in grams) of one die, one ball, and one marble is:

$d+m+b=25+20+30$

$d+m+b=75$

The total weight of one die, one ball, and one marble is 75 grams.

If the starting population of 5 rabbits grows at 200% each year, how many will there be 20 years?

alina1380 [7]

Growth rate = 200% each year
SO population becomes twice in each year

After 20 years, population = 5* 2^20 = 5242880

(Assuming no deaths occur)

For a recently released movie, the function y = 119.67(0.61)x models the revenue earned, y, in millions of dollars each week, x,

Marina CMI [18]

Given:
Function y = 119.67(0.61)x

x = week 3.

F(3) = 119.67(0.61)(3)
F(3) = 119.67*1.83
F(3) = 218.9961

x = week 5

F(5) = 119.67(0.61)(5)
F(5) = 119.67 * 3.05
F(5) = 364.9935

Help me pleaseeee I don’t understand this

user100 [1]

Answer:

Step-by-step explanation:

I don't understand in this specific context what is evaluated means but looking over the options it seems that 0 to the negative 1/2 power seems pretty unlikely . the only reason I don't say 0 to the negative 2nd power is because 0 to the negative 2nd power seems plausible but it doesn't seem like 0 to the negative 1/2 power would ever become a thing
