Answer:
1.-4,-1,1,6
2.by substituting the values given, we get
32-|15+8|
32-|23|
32-23=9
3.-15+7=8
4..27-(-12)=27+12=39
5.-6.05+(-2.1)
-6.05-2.1=-8.15
6.-3/4-(-2/5)
-3/4+2/5
=-7/20
7.-9(-12)
=108
8.(3.8)(-4.1)
-15.58
9.(-8x)(-2y)+(-3y)(z)
(16xy)+(-3zy)
(16xy)-(3zy)
10.by substituting the value given,we get
2.5*(-3.2)+5
-8+5
-3

Answer
Find out the how many notes of each denomination did she give .
To prove
Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.
As given
Kamala gave Rs 1,50,000 to her friend.
She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.
Rs50 currency note gave in the denomination = 4x
Rs100 currency note gave in the denomination = 3x
Rs500 currency note gave in the denomination = 5x
than the equation becomes
4x + 3x + 5x = 150000
12x = 150000
x = 12500
Thus
Rs50 currency note gave in the denomination = 4 × 12500
= 50000
Rs100 currency note gave in the denomination = 3 × 12500
= 37500
Rs500 currency note gave in the denomination = 5 × 12500
= 62500

No problem, that's why Brainly exists! :)
Karen is right, as every equilateral triangle has equal angles. The angles in every triangle must add up to 180°, and if all the angles are equal in an equilateral triangle, that must mean each angle is 60°. (180 ÷ 3 (because three sides in a triangle) = 60). Anything under 90° is acute, that means Karen is right because 60 < 90, and is therefore acute.
