Their are 6 equilateral triangles in a regular hexagon:
The area of one triangle = (x²√3)/4, then:
1st answer: The area of the hexagon base: is 6 TIMES the area of one equilateral triangle [or, needed for 2nd, question, TOT AREA:(6x²√3)/4] = (3x²√3)/2] unit²
2nd answer: :
Volume of pyramid: (base area)(height)/3
Volume of pyramid: (3x²√3).(3x)/3 (because height = 3x, given)
Then Volume of pyramid= 3x³√3 unit³.
3 is the answer for the second question
and 6 for the 1st
Answer:
a=4, b = -2
Step-by-step explanation:
Use elimination: subtract two equations. you get -6b = 12, so b = -2. Substitute this into the first equation and get a -8 = -4, so a = 4
Answer:
7/9
Step-by-step explanation:
First Fractions need to be same so bottom number is 9
So to get 1/3 to nine we need to do 3x3 which equals 9
So we are with 3/9 and 4/9. Add top numbers and u get 7/9
Time=distance/speed
621÷51.75
=12
So it takes 12 hours
6(G+9)
you have to use the distributive property.
6*G=6G
6*9=54
answer is 6G+54
