Answer:
5/8
Step-by-step explanation:
→ Work out how many red
8 - ( 2 + 1 + 2 ) = 3
→ Add up red and purple
3 + 2 = 5
→ Divide over total number of beads
5/8
Answer:
x = -11
Step-by-step explanation:
First, add three to both sides on the equation. Then, your equation becomes 55= -5x. Finally, divide both sides by -5 to get -11 = x. So, x equals -11. Hope this helps!
Answer:
12x the second -12x -16
Step-by-step explanation:
Solving systems of equations with 3 variables is very similar
Surface area SA:

Circumference C:

dividing this you get

and

Now let's input the radius

into the Surface area formula...
Answer:
b. 256
Step-by-step explanation:
Data:
W= 8
L= 8
H= 8
soln:
firstly the formula of lateral area is
LSA = (2W+2L) H
therefore:
LSA = (2×8+2×8) 8
LSA = (16+16) 8
LSA = (32) 8
LSA = 256
