Answer:

<h3>Nira's present age= 30</h3>

Step-by-step explanation:

her \: age \: before \: 10years \:  = x - 10 \\ her \: age \: after \: 10years \: = x + 10 \\ therefore.(x - 10) + (x + 10) = 60 \\ x - 10 + x + 10 = 60 \\ 2x = 60 \\ x = 60 \div 2  \\ x = 30 \\ hope \: it \: helps....

Answer:

I think Nira would be 30 years old

Step-by-step explanation:

So 10 years before and after her present age added together equals 60. So if she was 30, it would be 20+40 which =60.

Sorry for the wait.

Step-by-step explanation:

5. the two bottom angles are the same btw

2x+2x+x-15=180\\5x-15=180\\5x-15+15=180+15\\5x=195\\5x/5=195/5\\x=39

6. straight lines are 180

3x+17+x-9=180\\4x+8=180\\4x+8-8=180-8\\4x=172\\4x/4=172/4\\x=43

7. another 180

2x-4+3x+5+2x+11=180\\7x-10=180\\7x-10+10=180+10\\7x=190\\7x/7=190/7\\x=27.14\\

8. 90 degree angle

x+x+4+3x-9=90\\5x-5=90\\5x-5+5=90+5\\5x=95\\5x/5=95/5\\x=19

Determine whether the improper integral converges or diverges, and find the value of each that converges.
Vanyuwa [196]

Answer:

The integral diverges

Step-by-step explanation:

Consider the integral from 0 to infinity of

xe^{4x}

We can do this in parts

\int {xe^{4x} } \, dx =\int {x} \, d(e^{4x})/4\\ = x/4 e^{4x}-e^{4x}/16

When we substitute limits infinity we find that the values become infinity

Hence the integral diverges

The given improper integral diverges

What is the value of x? show work
Alona [7]
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71 

The unknown angles are each 71

You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
