Question 1 options: 3 8 12 2.5

Mathematics
1 answer:
rewona [7]3 years ago
5 0

Answer:

2.5

Step-by-step explanation:

(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)

\frac{2}{x}=\frac{12}{15}

Cross multiply

12x=30

Divide

x=2.5

This is just one way to do the problem. An easier way is to simplify the fractions.

\frac{2}{x}=\frac{4}{5}

You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5

A pattern rule is square, triangle, circle, oval. What is the 50th shape?
Svetlanka [38]

Patterns are used to represent sequence of numbers.

The shape at the 50th position is a triangle

The pattern rule is given as: square, triangle, circle, oval.

The number of shapes (n) is given as:

n =4

So, the 50th shape is calculated using the following absolute operator

Shape = 50\%4

i.e. divide 50 by 4, and take note of the remainder.

When 50 is divided by 4, the remainder is 2

So, we have:

Shape =2

This means that, the shape at the 50th position is the same shape at the 2nd position.

Hence, the shape is triangle
