Answer:
7+3^2(-5+1) divided by 2 is -11
Answer:
9)x=11 y=3
11)x=18 y=5
Step-by-step explanation:
9) 9x+25=13x+19 13x-19+17y+5=180
9x+44=13x 129+17y=180
44=4x 17y=51
11=x y=3
11) 49+3x=7x-23 3x=11y-1
Answer:
73°
Step-by-step explanation:
Given, Angle A = 17° and Angle B = 90°
As it is a triangle, sum of all the angles are 180°
so,
⇒ Angle A + Angle B + Angle C = 180°
⇒ 17° + 90° + Angle C = 180°
⇒ Angle C = 73°
The height of an equilateral triangle with side s is s*sqrt(3)/2
The area of an equilateral triangle is therefore s^2*sqrt(3)/4
The area of a hexagon with side s is 6 times the area of an equilateral triangle
=6*s^2*sqrt(3)/4
=3s^2*sqrt(3)/2
Here s=4,
Area of base (hexagon) = 3*4^2*sqrt(3)/2=24sqrt(3)
Volume of prism
=(base area)*height
=24sqrt(3)*9
=216sqrt(3)
