Darya [45]

Answer:

216

Step-by-step explanation:

I'm sure there is a simpler way to do this but this is how I did it.

First divide 18 by 6 because it triples every 6 hours.

18/6=3

This means it will triple three times

Then triple the value three times

#1. 8x3=24

#2. 24x3=72

#3. 72x3=216

In 18 hours the virus will infect 216 people.

The guttering hold up to 20 litre of rain water. Work out the length of guttering in meters if the diameter is 11.5cm.

bazaltina [42]

Answer:

1107.0213 cm

Step-by-step explanation:

Assuming this gutter is half a cylinder,

Volume of half a cylinder = 0.5(πr²l)²

where, Volume = 20l, π = 3.142, r = 0.5(11.5) and l = ?

But, the other units are in cm while the Volume is in liters, so let's convert the liters to cm³

It would be easier to convert the liters to m³ then to cm³ rather than converting directly. So,

1000 L = 1 m³

1 L = ?

1 ÷ 1000 = 0.001 m³

1 m³ = 1,000,000cm³

0.001 m³ = ?

0.001 x 1,000,000 = 1000 cm³

So, if 1 L = 1000 cm³

20 L = ?

20 x 1000 = 20,000 cm³

Thus, 20,000 = 0.5(3.142 x 0.5(11.5) x l)

20,000 = 0.5(3.142 x 5.75 x l)

20,000 = 18.0665l

Make l the subject and divide both sides by 18.0665

length = 1107.0213 cm

How many real number solutions does the equation have

Ksju [112]

You have to find the discriminat b^2 -4ac

If it is > 0, the function has two real solutions
if it is = 0, the function has one real solution
if it is <0, the function has no real solution

6^2 - 4(7)(3) = 36 - 84 = - 48

Answer c. no solution

What is the answer for 27^x=9^x-4

Arada [10]

<u>Answer:</u>

x = -8

<u>Step-by-step explanation:</u>

We are given the following expression which we are to solve for $x$ :

$2 7 ^ x = 9 ^ { x - 4 }$

For this expression, we will make the bases same on both sides of the equation and then equate the exponents equal to each other.

$(3^3)^x = (3^2)^{x-4}$

Multiplying the exponents and equating them to get:

$3 x = 2 ( x - 4 )$

$3 x = 2 x - 8$

$3 x - 2 x = - 8$

x = -8
