Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
Answer:
I'm dumb too, but i think its 12....
Step-by-step explanation:
Answer:
9.V=480
10.V=25.1
11.V=377
12.V=160
13.V=179.6
14.V=452.4
Step-by-step explanation:
9.V=l*w*h
V=10*8*6
V=480
10.V=pi*1^2*8
V=8pi
V=25.1
11.V=1/3pi*6^2*10
V=1/3pi*36*10
V=1/3pi *360
V=120pi
V=377
12.V=l*w*h/3
V=10*8*6/3
V=480/3
V=160
13.V=4/3pi*3.5^3
V=4/3pi *42.875
V=171.5/3pi
V=179.6
14.V=2/3pi*6^3
V=2/3pi*216
V=432/3pi
V=144pi
V=452.4
