a=180-117=63

b=180-81-63=36

so angle a is 63, and angle b is 36

How many zeros should have 5 to have 72 dividers?

xenn [34]

Hello,

nice as problem.

$| If\ a\ number\ x=a_1^{p_1}*a_2^{p_2}*a_3^{p_3}*....*a_n^{p_n}\\ the\ number\ of\ his\ dividers is:\\{p_1+1}*{p_2+1}*{p_3+1}*....*{p_n+1}$
Here x has a power of 5 as divider and a power of 2 as divider (in order to make a power of 10.

$5=5^1*2^0$

$50=5^1*(5^1*2^1)=5^2*2^1$

$500=5^1*(5^2*2^2)=5^3*2^2$

$50 000 000=5^8*2^7$

Numbers of dividers: (8+1)*(7+1)=9*8=72

A chef cooked 7 kilograms of food for dinner. He ate 11/12 of the amount, how much did he eat?

Bogdan [553]

11/12 of 7 is simply their product.

$\bf 7\cdot \cfrac{11}{12}\implies \cfrac{77}{12}\implies 6\frac{5}{12}$

Line AB passes through points A(–6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y = mx + b,

Tresset [83]

(-6,6)(12,3)
slope(m) = (y2 - y1) / (x2 - x1) = (3 - 6) / (12 - (-6) = -3 / 18 = -1/6

y = mx + b
slope(m) = -1/6
use either of ur points (12,3)....x = 12 and y = 3
now sub and find b, the y int
3 = -1/6(12) + b
3 = -12/6 + b
3 = -2 + b
3 + 2 = b
5 = b

so ur slope(m) = -1/6 and ur y int (b) = 5
