You have an aquarium in the shape of a rectangular prism. The base is 4 feet by 3 feet. The height is 2 feet. How many square feet of glass were used to build the aquarium? (The top of the aquarium is open.)

Answers

Answer 1

Answer: Since it is about only the outer part of the aquarium which is made of glasses we need to calculate the total surface area.

Surface area of the base = 4*3 = 12 square feet

Surface area of the shorter length of wall = 3*2 = 6 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
6*2 = 12 square feet

Surface area of the longer length of wall = 4*2 = 8 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
8*2 = 16 square feet

Therefore the total surface area that need to be covered with glasses
12+12+16 = 40 square feet

There were 1200 boys at a school assembly. The ratio of boys to girls at the assembly was 20:23. How many girls were at the assembly?

Answers

The required number of girls in the school assembly is 1380.

Given,
There were 1200 boys at a school assembly. The ratio of boys to girls at the assembly was 20:23. Number of girls in the assembly line is to be determined

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Representation of ratio of two values a and b, ratio = a:b.

Let the number of girls in the school assembly be x.
There were 1200 boys at a school assembly. The ratio of boys to girls at the assembly was 20:23. So the ratio can be written as,
1200 : x = 20 : 23
1200 / x = 20 / 23
x = 1200 * 23 / 20
x = 60 * 23
x = 1380
Here, the number of girls in the school assembly is 1380.

Thus the required number of girls in the school assembly is 1380.

When a number is a multiple of 2 what are the possible values for the ones digit

Answers

Answer:

The correct answer is 2,4,6,8 and 0.

Step-by-step explanation:

A number is considered a multiple of 2 when it contains the number 2 repeated several times.

For example the number 8, contains the number 2 repeated 4 times = 2 + 2 + 2 + 2 = 8

It can also be a multiple of 2, any number multiplied by two. For example 6 is a multiple of 2 since 2x3 = 6

In simple words, all even numbers, or all numbers multiplied by 2, are multiples of 2.

2x0 = 0

2x1 = 2

2x2= 4

2x3 = 6

2x4 = 8

2X5 = 10 ...

The possible values for the ones digit are 0, 2, 4, 6, or 8.
