What decimal is represented by this expanded form?5 x 10,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6 1/1,000 + 4 x 1/,000

Answers

Answer 1
Answer: 5 x 10,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6 (1)/(1000) + 4 x (1)/(1000)

you want to make the 6 (1)/(1000) into a whole number:
6 (1)/(1000) = 6.001

new equation:
5 x 10,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6.001 + 4 x (1)/(1000)
50,000 + 3 x 1,000 + 2 x 10 + 8 x 1 + 6.001 + 4 x (1)/(1000)
50,000 + 3,000 + 
2 x 10 + 8 x 1 + 6.001 + 4 x (1)/(1000)
50,000 + 3,000 + 20 + 8 x 1 + 6.001 + 4 x (1)/(1000)
50,000 + 3,000 + 20 + 8 + 6.001 + 4 x (1)/(1000)
50,000 + 3,000 + 20 + 8 + 6.001 + .004
53,000 + 20 + 8 + 6.001 + .004
53,020 + 8 + 6.001 + .004
53,028 + 6.001 + .004
53,034 + .004
=53,034.005

What times what equals 20

Answers

There can be multiple answers to this question.

20 × 1 = 20
10 × 2 = 20
5 × 4 = 20

The solution is:

1 times 20 equals 20

2 times 10 equals 20

4 times 5 equals 20

Here, we have,

given that,

we have to find what times what equals 20.

now, let the numbers be x and y

so, we get, x × y = 20

now, we know that,

the numbers that make 20 are: 1, 2, 4, 5, 10, 20

so, we get,

There can be multiple answers to this question.

as, we have,

20 × 1 = 20

10 × 2 = 20

5 × 4 = 20

Hence, The solution is:

1 times 20 equals 20

2 times 10 equals 20

4 times 5 equals 20

A jar contains 65 coins, all of which are nickels and dimes. The total value of the coins in the jar is $5.40. How many nickels / dimes are in the jar?

Answers

Answer:

43 dimes, 22 nickels

Step-by-step explanation:

n + d = 65....this is just dealing with the total number of coins

0.05n + 0.10d = 5.40....this is dealing with the actual $ amount...nickels are worth 0.05 and dimes are worth 0.10

n + d = 65....n = 65 - d

now we sub that back into our other equation

0.05(65 - d) + 0.10d = 5.40

3.25 - 0.05d + 0.10d = 5.40

-0.05d + 0.10d = 5.40 - 3.25

0.05d = 2.15

d = 2.15 / 0.05

d = 43 <==== 43 dimes

n + d = 65

n + 43 = 65

n = 65 - 43

n = 22 <=== 22 nickels

at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amount of kids and adults sold meals sold?

Answers

I would set up a proportion:

(20)/(x)=(5)/(4)

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals."  Just cross multiply and then solve for x:

(20)/(x)=(5)/(4)\n5x=80\nx=16

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.
5x=20\ \ \ \ | divide\ by\ 5\n\nx=4\n\n5x+4x=9x=9*4=36\n\nCombine\ amount\ is\ 36.
