Answer:

Country A produces 20,000,000 & Country B produces 5,000,000

Step-by-step explanation:

Let

amount of diamonds produced by country A be x

and

amount of diamonds produced by country B be y

Since, Country A produces 4 times that of Country B, we can write:

x = 4y

Also, both countries produces a total of 25,000,000 carats, so we can write:

x + y = 25,000,000

Now, we need to find x and y. Putting 1st equation into 2nd equation, we get equation in y. Then we solve for y:

x + y = 25,000,000

4y + y = 25,000,000

5y = 25,000,000

y = 25,000,000/5

y = 5,000,000

And now, x = 4y, so x = 4(5,000,000) = 20,000,000

So Country A produces 20,000,000 & Country B produces 5,000,000 diamond carats

If m is perpendicular to n, solve for x
bixtya [17]

x + 21 + 3x + 9 = 90

Combine like terms

4x + 30 = 90

Subtract 30 from both sides

4x = 60

Divide both sides by 4

x = 15

Barney is eight years older than Nemo. In seven years the sum of their ages will be 46. How old is Barney now?.
olga55 [171]
Let's represent Nemo's age with an n.

Barney is 8 years older so his age is nemo's plus 8. That is, Barney's age is n + 8

In seven years they will each be the age they are now plus 7. So, Nemo will be n + 7 and Barney will be n + 8 + 7. If the sum of their ages will be 46 we know that when we add these expressions we should get 46, so let's set the sum to 46 and solve for n.

n + 7 + n + 8 + 7 = 46
2n + 22 = 46
2n = 46 - 22
2n = 24
n = 12

That means that Nemo's age is 12.
Since Barney is 8 years older his age is 12 + 8 = 20.

To check our work we see that in 7 years Nemo will be 12 + 7 = 19 and Barney will be 20 + 7 = 27. Together that is 19 +27 = 46 as expected.

The graph below shows the distance in miles, m, hiked from a camp in h hours.
Artist 52 [7]

Answer:

Option 1) is correct

Step-by-step explanation:

Given: The graph shows the distance in miles, m, hiked from a camp in h hours.

To find: hourly interval that had the greatest rate of change

Solution:

Rate of change between two points refers to the vertical change divided by the horizontal change.

For hour 0 to hour 1:

rate of change = \frac{2-0}{1-0}=2

For hour 2 to hour 3:

rate of change = \frac{4.5-3.5}{3-2}=1

For hour 1 to hour 2:

rate of change = \frac{3.5-2}{2-1}=1.5

For hour 3 to hour 4:

rate of change = \frac{5-4.5}{4-3}=0.5

So, rate of change is greatest in interval: hour 0 to hour 1
