Ok, to solve this first you have to set up your proportion:

9/150=x/230

/ is a fraction

x= the number of vials it will take to treat 230 patients

in order to solve this, you have to cross multiply:

9 x 230= 2070

150 · x= 150x

so you get 150x=2070

then divide 2070 by 150

2070/150= 13.8

so it would take 13.8 vials of medicine to treat 230 patients

<span>Okay, firstly, you want to work out how many people will 1 vial of malaria treat. So, you do this: 

150 divided by 9= </span><span>16.6

</span><span>That means for every 1 vial, 16.6 people are treated.
</span>
<span>Since the question asks you to find out how many vials are needed if you're required to treat 230 people, you would do this:
</span>
230 divided by 16.6= <span>13.8

</span>That means you need 13.8 vials to treat 230 people.

Why is it helpful to write numbers in different ways
Goshia [24]
You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.

Writing one in many different ways:

1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)

=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)

=(1/4)+(1/4)+(1/4)+(1/4)

Writing a half in many different ways:

1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)

=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)

=2/4=3/6=4/8=5/10=0.5=0.50

etc...etc...

X^4-28x^2=0 solve algebraically
Paha777 [63]
x^4 - 28x^2  = 0

x^2(x^2 - 28) = 0

x^2 = 0 \ \ or \ \ (x^2 - 28) = 0

x = 0 \ \ or \ \ x^2 = 28

x = 0 \ \ or \ \ x = \pm \sqrt{28}

x = 0 \ \ or \ \ x = \pm2 \sqrt{7}

---------------------------------------------------
Answer : x = 0 or 2√7 or -2√7

Let's say Jose deposited $2,700 into a CD account with an Annual Percentage Rate
sergey [27]

Answer:

$3283.2

Step-by-step explanation:

Given data

Principal= $2700

Rate= 4%

Time= 5 years

Required

the final Amount A

The compound interest formula is

A=P(1+r)^t

Substitute

A=2700(1+0.04)^5

A=2700(1.04)^5

A=2700*1.216

A=$3283.2

Hence the balance in the account after 5 years is $3283.2
