Here's a rule of thumb that works for these probability questions.
Let say there are 5 objects and you can 3 of them. Then the total number of ways are:
5x4x3=60
This is because at the beginning there are 5 objects to choose from, after one is chosen, there's only 4 left. After another one is chosen, there is only 3 left. That's when you are done with your 3 turns to choose.

Find the distance between (2,4) and (12, 9) on a coordinate plane. round to the nearest tenth if necessary. *
atroni [7]
Use pythagoras

d = √(Δx² + Δy²)
d = √(12-2)² + (9-4)²
d = √(10² + 5²)
d = √(100 + 25)
d = √125
d = 5√5
d = 5 × 2.236
d = 11.18

The nearest tenth is 11.2, so the distance is near to 11.2

How to solve this equation algebraically: Y=2x+1<br> 3x+4y=26
AURORKA [14]
You can substitute what y is into the second equation, so:
3x + 4(2x + 1) = 26
3x + 8x + 4 = 26
11x + 4 = 26
- 4
11x = 22
÷ 11
x = 2

y = (2 × 2) + 1
y = 5 + 1
y = 5

So you get x as 2 and y as 5, I hope this helps!

In the triangle below,<br> y = [ ? ] cm. Round to the<br> nearest tenth.
sattari [20]

Answer:

The answer is

<h2>12.3 cm</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find y

To find y we use cosine

cos∅ = adjacent / hypotenuse

From the question

y is the adjacent

The hypotenuse is 15

So we have

\cos(35)  =  \frac{y}{15}  \\ y = 15 \cos( 35 )  \\ y = 12.28728

We have the final answer as

<h3>12.3 cm to the nearest tenth</h3>

Hope this helps you
