An artist is using tiles and boards for a project. A tile has length 1/4 ft and width 1/4 ft. A board has length 1/4 yd and width 1/4 yd. What is the ratio of the length of the tile to the length of the​ board? What is the ratio of the area of the tile to the area of the​ board?

Answers

Answer:

Ratio of lengths is 1:3

Ratio of areas is 1:9

Step-by-step explanation:

Firstly, we need the units to be same

Mathematically, 1 yard = 3 feet

A length of 1/4 yards = 1/4 * 3 = 3/4 feet

A width of 1/4 yards = 1/4 * 3 = 3/4 feet

The ratio of the length of the tile to the length of the board

that would be;

1/4 : 3/4 = 1: 3

Let’s now work with area

Mathematically, area in both cases is length * width

For the board, we have that;

3/4 * 3/4 = 9/16 square feet

For the tile, we have that;

1/4 * 1/4 = 1/16 square feet

so the ratio of the tile area to the board area will be;

1/16 : 9/16 = 1: 9

There are 156 laptops and desktop computers in a lab. There are 8 more laptops than deskto
computers. What is the total number of desktops in the lab?

Answers

Answer:

It would be 70

Step-by-step explanation:

First step: Divide 156 by 2

156 / 2 =  78

Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that  "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).

78 - 8 = 70 Desktops  

78 + 8 = 86 Laptops

Hope this helps :)

Polly's veterinarian told her a dog that weighs w kilograms needs 30w+70 calories each day to stay healthy. Polly's dog, Otis, weighs 22 kilograms. How many calories does Otis need each day to stay healthy?

Answers

Answer: 730 calories

Step-by-step explanation:

Since the function is given as: 30w+70 and Polly's dog, Otis, weighs 22 kilograms.

The amount of calories that Otis need each day to stay healthy will be:

= 30w + 70

= 30(22) + 70

= 660 + 70

= 730 calories

150% of what number is 49?

Answers

Answer:

32 2/6

Step-by-step explanation:

150% of what number is 49

Can be written as;

1.5x = 49

( To find the percent of a number, one has to move the decimal back two spaces on the percent ( because a percent is out of 100), and then multiply by the number)

Use inverse operations to solve;

1.5x = 49

/1.5     /1.5

x = 32 2/3
