The google family built a rectangular swimming pool in their backyard.The floor of the pool has an area of 485 5/8 square feet.If the width of the pool is 18 1/2 feet,what is the length of the pool?

Answers

Answer 1

A= Area= 485 5/8 ft^2
W= Width= 18 1/2 ft
L= Length= ?

Area= LW
plug in known numbers

485 5/8= (L)(18 1/2)
convert to improper fractions

3885/8= (L)(37/2)
divide both sides by 37/2

3885/8 ÷ 37/2= L
to divide fractions, multiply by the reciprocal/inverse of 37/2

3885/8 * 2/37= L
multiply numerators; multiply denominators

(3885*2)/(8*37)= L
multiply inside parentheses

7770/296= L
simplify

105/4 feet= L
change to mixed number

26 1/4 feet= L

ANSWER: The length is 26 1/4 feet (or 26.25 feet).

Hope this helps! :)

Answer 2

Area = Length x Width

[tex]485 \dfrac{5}{8} = 18 \dfrac{1}{2} \times \text{ Width}[/tex]

Divide both side by 18 1/2:
[tex]\text{ Width} = 485 \dfrac{5}{8} \div 18 \dfrac{1}{2} [/tex]

Convert to improper:
[tex]\text{ Width} = \dfrac{3885}{8} \div \dfrac{37}{2} [/tex]

Change divide fraction to multiplicationf fraction:
[tex]\text{ Width} = \dfrac{3885}{8} \times \dfrac{2}{37} [/tex]

Mutliply and simplify:
[tex]\text{ Width} = \dfrac{104}{4} = 26 \dfrac{1}{4} \text{ feet}[/tex]

Answer: Length = 26 1/4 feet

charlene is a video game designer and wants to make sure that her game can be played on all types of screens. In order for the games to work on both devices with a standard aspect ratio and those with widescreen aspect ratios, the playable area of the games should an aspect ratio of 3:2. This means that the width is equal to 3/2 times the height. On one type of tablet , the playable area of the game on the screen is 54 square inches. Write and solve a system of equations to determine the dimensions of the playable are.

A) width=6 height=9
B) width=6 height=4
C) width=13.5 height=9
D) width=9 height=6

Answers

The correct answer is D) width=9, height=6.

Let w represent the width and h represent the height. The first equation we write deals with the area of the screen:
A=wh

Our playable area is 54, so we have
54=wh

Now we write the equation relating the width and the height. The width is 3/2 times the height; this means
w=3/2h

We will use substitution to solve this. Substitute the value for w from the second equation into the first equation:
54=wh
54=(3/2h)h
54=3/2h²

Divide both sides by 3/2:
54 ÷ 3/2 = 3/2h² ÷ 3/2
54/1 ÷ 3/2 = h²
54/1 × 2/3 = h²
108/3 = h²
36 = h²

Take the square root of both sides:
√36 = √h²
6 = h

The height is 6. Substituting this into our first equation,
54=wh
54=w(6)

Divide both sides by 6:
54/6 = w(6)/6
9=w

The width is 9.

Answers

This is the concept of speed, distance and time:
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then

Answer : The numbers are 21 and 28.

Hope this helps. - M

The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.

To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.

The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.

Subtract the first equation from the second to find the value of s.

2s + l - (s + l) = 70 - 49

Which simplifies to:

s = 21

Substitute the value of s into the first equation:

21 + l = 49

And solve for l:

l = 28

Therefore, the smaller number is 21 and the larger number is 28.
