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

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

A software CD can be manufactured for $0.10 each. The development cost to produce the CD is $500,000. The first 200 CDs were used by testers to test the functionality of the software and were not sold.
Write a function, f, for the average cost, in dollars, of a saleable software CD where x is the number of saleable software CDs.
Answers
Answer:
The function that represents the average cost in dollars of saleable software CD is given as follows;
f(x) = 500,020/x + 0.10
Step-by-step explanation:
The given parameters are;
The cost of manufacture of each software CD = $0.10
The development cost to produce the CD = $500,000
The number of CDs that are not sold = The first 200 CDs
The total cost of production. 'C', of the the CD is given as follows;
C = $500,000 + $0.10×200 = $500,020
The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;
f(x) = (C + 0.10·x)/x = C/x + 0.10
∴ f(x) = 500,020/x + 0.10.

B) x = -2
C) x = 2
D) x = 5.2
E) x = 6.5
Answers
Answer:
A and D
Step-by-step explanation:
I could be wrong but the solutions are the points of intersection between the two functions. By looking at it. I can see that its about -3.3 and 5.2
Hope this helps!
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.,Functions which repeats their values after a fixed interval, are called periodic function.
WE have been given the function x as
f (x) = g(x)
Therefore,
3(17x-6.5) = 108
Then Divide each side by 3;
3/3(17x-6.5) = -108/3
17x - 6.5 = -36
Add 6.5 to each side;
17x-6.5+6.5 = -36+6.5
17x = 42.5
Divide by 17;
17x/17 = -42.5/17
x = -3.3
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.
