Iliana is painting a picture. She has green, red, yellow, purple, orange, and blue paint. She wants her painting to have four di
ivanzaharov [21]

The number of ways for which she could pick four colours if green must be one of them is; 10 ways.

<h3>How many ways can she picks four colours if green must be there?</h3>

It follows from the task that there are 6 colours in total that she could pick from.

Hence, since she needs four colours with green being one of them, it follows that she only has 3 colours to pick from 5.

Hence, the numbers of possible combinations is; 5C3 = 10 ways.

HURRY PLEASE!!! I NEED TO TURN THIS IN SOON<br><br> i need an explanation too.
Dominik [7]

Answer:

X = 30°, y = 15° and z = 150°.

Reason: Look below.

Step-by-step explanation:

Hey there!

When we look into the figure, we find that;

For x:

x+ 2x + 90° = 180° {Being linear pair}

or, 3x = 180°-90°

or, 3x = 90°

or, x= 90°/3

<u>Therefore, X = 30°.</u>

For y :

2y = x = 30° {Alternate angles are equal}

or, 2y = 30°

y = 30°/2

<u>Therefore, y = </u><u>1</u><u>5</u><u>°</u>

For z:

2y + z = 180° { Being linear pair}

or, 30°+z = 180°

or, z = 180°-30°

or, z = 150°

<u>Therefore, z = 150°.</u>

So I = Prt 

I for interest charge 
P for principal ($4,840)  
r for rate (6%)
t for time (2 yrs) 

So you would then plug the information into the equation.....

I = 4,840*.06*2 
I = 580.80 

So the answer to your question is $580.80 which is option B

Hope this helps! :)
