The sum of 6 consecutive even numbers is 270.What is the second number in this sequence?
Finger [1]

Answer: 42

Step-by-step explanation:

Let the six consecutive even numbers be x , x+2 , x+4 ,x+6 ,x+8 ,x+10.

Then According to the question , we have

x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=270\\\\\Rightarrow\ x+x+2+x+4+x+6+x+8+x+10=270\\\\\Rightarrow\6x+30=270\\\\\Rightarrow\ 6x=270-30\\\\\Rightarrow\ 6x=240\\\\\Rightarrow\ x=40

Now, the second number from the above six consecutive even numbers  is x+2.

Substitute the value of x in it, we get

The second number in this sequence = x+2=40+2=42

Let the number total slices = x

He ate (1/4) x

He has x - 1/4 x = 3/4 x slices left.

Each one of these slices is cut into 1/8s

T (total number of slices) = 8 * (3/4x)

T = (8*3/4) x

T = (24/4)x

T = 6x slices.

KIM [24]

Answer:

In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

What is the area of the yellow triangle?
lesantik [10]

I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.

For example, the dimensions of a triangle are 4 and 6.

Multiply the two.

4x6=24.

But don't stop there. Divide 24 by 2.

24/2=12.

So the area of the example triangle is 12.

hope it helps
