Step-by-step explanation:
Answer:
2 3/4 C
Step-by-step explanation:
V = V 1 + V 2 + V 3 =
= 4² · 8 + 4² · 12 + 4² ·8 =
= 4² · ( 8 + 12 + 8 ) =
= 16 · 28 = 448
Answer:
The volume of the composite figure is 448 yd³.
5.
there are 180 degrees in any triangle and 105 is more than half of 180 so 105 is obviously the biggest then DCE looks bigger than CDE so the order from smallest to bigest is CDE,DCE, CED
6. 180 degrees in any triangle so the right angle is 1/2 of that so it's the biggest angle
side HI has a legth of 4 while side GI has a side legnth of 6 so angle GHI is bigger than angle IGH so the order from smallest to biggest is IGH, GHI, GIH
Ruby worked X + 8
Isaac worked X
Svetlana worked 3(X+8)
Let's combine all of that by putting it in an equation
X+8+x+3(x+8)=150
Do what's in parentheses first
x+8+x+3x+24=150
Now we add likes
X+x+3x+8+24=150
5x+32=150
We want x on one side of the equation & numbers on the other side
5x+32-32=150-32
5x=118
Solving for X
5x/5=118/5
X=23.6
Isaac worked 23.6
Ruby worked 8 more hours than Isaac so we add 8 to 23.6= 31.6
Svetlana worked 3 times Ruby so 3x31.6= 94.8
