What is the value of the following expression? 7 + 18 divided by 3

1 answer:

4 0

If the question is this: 7+18÷3, than you would have to use PEMDAS, the order of operations. So, you would divide 18 by 3, which is 6, and then add it to 7, which is 13.

However, if the question is asking you to add 7 and 18 first, then you have to do that, which is 25, and then divide that by 3, which is 8 $\frac{1}{3}$ .

Select the correct answer from each drop-down menu. Complete the statements about these similar pyramids. Two square pyramids A

Scrat [10]

The ratio of the heights of these pyramids is 3 : 1, the ratio of the base areas is 9 : 1 and the ratio of the volumes is 27 : 1.

<h3>What is ratio?</h3>

Ratio can be defined as a mathematical expression which denotes the proportion of two (2) or more physical quantities to one another and the total quantities.

The ratio of the heights of these pyramids is given by:

Ratio = Height of pyramid A : Height of pyramid B

Ratio = (3V/lw) : (V/lw)

Ratio = 3 : 1.

The ratio of the base areas of these pyramids is given by:

Ratio = Base area of pyramid A : Base area of pyramid B

Ratio = (3a)² : a²

Ratio = 9a : a

Ratio = 9 : 1.

The ratio of the volumes of these pyramids is given by:

Ratio = Volume of pyramid A : Volume of pyramid B

Ratio = (3l × 3w × 3h)/3 : (l × w × h)/3
