V=(1/3)Ah
A=a*b for squares and a*b/2 for right triangles

1)
A=6*8.5=51
V=51*12/3=51*4=204in^3

2)
A=12*6=72
V=72*15/3=72*5=360ft^3

3)
A=18*24/2=18*12=216
V=216*35/3=72*35=2520cm^3

4)
A=26*15/2=13*15=195
V=195*38/3=65*38=2470cm^3

5)
A=B=8ft^2
V=8*12/3=8*4=32ft^3

Let S be the universal set, where: S={1,2,3,...,18,19,20}

just olya [345]

Answer:

A∪B = {1,2,3,4,5,6,7,8,9,11,13,14,15,16,18,20}

A∩B = {1,5,6,7,8,9,11,14,15}

Step-by-step explanation:

A∪B is the elements in A or B. So, for this question, we just need to find the numbers that are in A or B. Remember not to add anything that is not in set A or B and not write the same number twice.

A∩B is the elements in A and B. Therefore, for this question, we just need to find the numbers which appeared in both set A and B.

Hope this helps :)

There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.

igor_vitrenko [27]

Answer:

The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =

Cost(c)= 1/8($15.68 × 6)

The cost (c) if you buy 6 jars of jellyfish jelly is $11.76

Step-by-step explanation:

There are 8 jars of jellyfish jelly for $15.68. Write a proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly.

The proportion is given as:

Number of jars of Jellyfish/Cost of the Number of jar of Jellyfish

Hence:

8/$15.68 = 6/c

We Cross Multiply

8 × c = $15.68 × 6

c = $15.68 × 6/8

c = $11.76

Therefore,

The proportion that gives the cost (c) if you buy 6 jars of jellyfish jelly =

Cost(c) = 1/8($15.68 × 6)

The cost (c) if you buy 6 jars of jellyfish jelly is $11.76
