Step-by-step explanation:
V = (12*4*5) + (2*3*5) + (5*3*5) + (12*4*5)
V = 240 + 30 + 75 + 240
V = 585 cm^3
The answer would be 230 2/3, because to get the perimeter you have to add all the sides together, 60 5/6 + 59 1/3 + 56 1/6 + 54 1/3 = 230 2/3
Answer:
There are 26 purple marbles in the bag.
Step-by-step explanation:
Firstly, you have to make an expression in terms of x where x represent red marbles. Given that the question says purple marbles is 2 more than 3 times the number of red marbles. So the expression is :
Let red marbles = x,


Next, given that the total marbles in the bag is 34 so you have to add both marbles together and solve the value of x :




Lastly, you have to substitute the value of x into the expression of purple marbles :
Let x = 8,


10.2
and
5.6
and
7.9
Hope this helped :)
Divide 22.2 by 4 since the perimeter is the outside and there are 4 edges
