Answer:

Step-by-step explanation:

All the angels of a triangle always add up to 180

(2x-15)+(x+43)+x = 180

Multiple the numbers inside the parentheses first

-30x+43x+x = 180

Add common terms

14x = 180

Divide by 14 to get the variable by itself

x ≈ 12.86

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?

PtichkaEL [24]

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

$1000^{2015}$

We have to find the number of digits ,

So,

$1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}$

Since we know that

$10^n\text{ has n+1 number of digits }$

so,

$10^{6045}\text{ has 6046 number of digits }$

Hence, there are 6046 digits will be written on expansion upto 2015th power.

What is the midpoint coordinates of segment HX H(13,8) X(-6,-6)

Setler79 [48]

Midpoint of (x1,y1) and (x2,y2) is

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

so the midpoint of HX is the mdpoint of (13,8) and (-6,-6)
which is

$(\frac{13-6}{2},\frac{8-6}{2}=$
$(\frac{7}{2},\frac{2}{2}=$
$(3.5,1)$

the midpoint is (3.5,1)
