The pattern is multiply by 5

2 x 5 = 10

10 x 5 = 50

50 x 5 = 250

250 x 5 = 1250

Answer

The next two terms: 250 and 1250

2, 10, 50,250, 1250

Hi!

Let's try to find the pattern.

Is it adding?

2, + 8 = 10, + 8 = 18

Nope. 10 + 8 = 18, not 50.

Is it subtracting?

2 - (-8) = 10 - (-8) = 18

Nope. 10 - (-8) = 18, not 50.

Is it multiplying?

2 x 5 = 10 x 5 = 50

Yes! Now continue the pattern.

50 x 5 = 250 x 5 = 1250

The sequence is

2, 10, 50, 250, 1250

Hope this helps! :)

1/3(6z+7.2)=0.5(8z+2)-0.4 please hurry this is for now

Crazy boy [7]

Answer:

z = - 0.78

Step-by-step explanation:

Given:

1/3(6z+7.2)=0.5(8z+2)-0.4

Open parenthesis

2z + 2.4 = (4z + 1) - 0.4

2z + 2.4 = - 1.6z - 0.4

Collect like terms

2z + 1.6z = - 0.4 - 2.4

3.6z = -2.8

z = -2.8 / 3.6

= - 0.78

Lionfish are considered an invasive species, with an annual growth rate of 67%. A scientist estimates there are 8,000 lionfish i

ICE Princess25 [194]

There would be 173,535 lionfish after 6 years.

Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:

A)
8000 x 1.67 ^ n = f
B)
8000 x 1.67 ^ 6 = X
8000 x 21.691961596369 = X
173,535.692770952 = X
C)
(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f

Therefore, there would be 173,535 lionfish after 6 years.

Am I correct if not help plzzz

Hey there!

You got the first part right where you added r to both sides. However, you need to make sure that you complete all actions on both sides, including canceling out parts of terms by division. The only thing you need to do is divide both sides by h instead of just the left. This will make your answer:

$y = \frac{b+r}{h}$

Hope this helped you out! :-)

At the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner diameter is 22yd and its ou

jeka94

First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.

The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:

22/2 = 11 yards
32/2 = 16 yards

Then solve for the area of both circles.
π $11^{2}$ $= 121$ π ≈ <span>380.13 (area of the pool)</span>
π $16^{2}$ $= 256$ π ≈ <span>804.25 (area of the whole thing)
</span>
Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
$804.25 - 380.13 = 424.12$ (area of the walkway)

Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:

424.12 ÷ 6 ≈ 70.69

So you'll need 71 gallons of paint!

Hope I helped and let me know if you have any questions :)
