Answer:

x=2

Step-by-step explanation:

assuming this shape is euclidean (don't pay attention to this just some extra info, assume that all triangles on a sheet of paper have angles summing to 180)

The sum of all angles in a triangle is 180, so

90+60+15x=180

150+15x=180

15x=30

x=2

5m - 2 ≤-14 or -2m ≤ -15

Vera_Pavlovna [14]

the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.

First inequality:

5m - 2 ≤ - 14

Add 2 to both the sides:

5 m - 2 + 2 ≤ - 14 + 2

5 m ≤ - 12

Divide both sides by 5:

5 m / 5 ≤ - 12 / 5

m ≤ - 2.4

Other inequality:

-2m ≤ -15

Divide both sides by 2:

-m ≤ -7.5

m ≥ 7.5

So, we get:

m ≤ - 2.4 or m ≥ 7.5

Therefore, we get that, the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.

A type of bacteria has a very high exponential growth rate of 80% every hour. If there are 10 bacteria, determine how many will

Lana71 [14]

<h3>There are 189 bacteria in 5 hours</h3><h3>There are 13382588 bacteria in 1 day</h3><h3>There are $10(1.8)^{168}$ bacteria in 1 week</h3>

<em><u>Solution:</u></em>

Given that,

A type of bacteria has a very high exponential growth rate of 80% every hour

There are 10 bacteria

<em><u>The increasing function is given as:</u></em>

$y = a(1+r)^t$

Where,

y is future value

a is initial value

r is growth rate

t is time period

From given,

a = 10

$r = 80 \5 = \frac{80}{100} = 0.8$

<em><u>Determine how many will be in 5 hours</u></em>

Substitute t = 5

$y = 10(1 + 0.8)^5\\\\y = 10(1.8)^5\\\\y = 10 \times 18.89568\\\\y \approx 188.96$

y = 189

Thus, there are 189 bacteria in 5 hours

<em><u>Determine how many will be in 1 day ?</u></em>

1 day = 24 hours

Substitute t = 24

$y = 10(1 + 0.8)^{24}\\\\y = 10(1.8)^{24}\\\\y = 10 \times 1338258.84\\\\y = 13382588.45\\\\y \approx 13382588$

Thus, there are 13382588 bacteria in 1 day

<em><u>Determine how many will be in 1 week</u></em>

1 week = 168

Substitute t = 168

$y = 10(1 + 0.8)^{168}\\\\y = 10(1.8)^{168}$

Thus there are $10(1.8)^{168}$ bacteria in 1 week
