Answer:

15 cm squared

Step-by-step explanation:

The area of a triangle is: \frac{bh}{2}, where b denotes base and h denotes height.

In the problem, we see that the base is 15, so b = 15, and the height is 2, so

h = 2. Now, we just plug these values into the equation:

A = \frac{2*15}{2} = 15

Thus, our answer is 15 cm squared.

Express the recurring decimal 0.142 recurring as a fraction in its simplest form.
kupik [55]

Answer:

7/165

Step-by-step explanation:

We take number after the decimal point     042

then we subtract  the non repeating.In this case is 0 so we not subtract anything

This will be the numerator  42

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990  =  7/165

7:165 = 0.0424242

I think this is what you do. Hope it helps!

2b=6a-14,3a-b=7 how to work it out
pshichka [43]
So, since there are two equations, we can substitute one of them into the other. In this case, it would be easiest to substitute 2b=6a-14 into the other equations. But first, simplify by dividing both sides by 2. You bet b=3a-1

We can now plug this into the other equation
Sine the equation b=3a-1 results in the value of b, we have to plug in for the value of b in the other equation

So this is what we get after plugging in:
3a-(3a-1)=7
Now, simplify. 3a-3a+1=7
Since 3a-3a = 0, this equation results in a no solution

Answer:
The result is a no-solution, or Ф

Hope this helped!! :D
