Adam's music playlist contains songs he bought and songs his mother bought. The ratio of his songs to his mother's songs is 5:3. How could you complete the table of equivalent ratios?​

Answers

Answer:

The ratio of the songs is 5:3

Step-by-step explanation:

This means that for every 5 songs Adam has, his mother has 3. We can do that in intervals of 5:3, with 10:6, 15:9, 20:12, and etc.

Write "15" in Adam's column and "24" in his mother's column.

In the given question, the table of equivalent ratios is missing. Please find the attachment of that table below.

Given ratio is:

The ratio of Adam's songs to his mother's songs,

5:3

then,

→  [tex]\frac{Adam's \ songs}{Mother's \ songs} =\frac{5}{3}[/tex]

→ [tex]Adam's \ songs = \frac{5}{3}\times 9[/tex]

→                         [tex]= 15[/tex]

Now,

→       [tex]\frac{40}{Mother\s \ songs} =\frac{5}{3}[/tex]

→                [tex]40\times \frac{3}{5} = Mother's \ songs[/tex]

Step-by-step explanation:

Simplify the numerator and the denominator.

The square root of 4/49 is 2/7.

Given that a fraction 4/49 we need to find the square root of this fraction,

To find the square root of a fraction, you need to find the square root of both the numerator and the denominator separately. Let's apply this to the fraction 4/49.

Step 1: Find the square root of the numerator:

The numerator is 4. Taking the square root of 4 gives us √4 = 2.

Step 2: Find the square root of the denominator:

The denominator is 49. Taking the square root of 49 gives us √49 = 7.

Step 3: Form the new fraction:

The square root of the fraction 4/49 is (√4)/(√49), which is 2/7.

Therefore, the square root of 4/49 is 2/7.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y = 2x - 1/2

At x = 0, the value of the variable 'y' will be given as,

y = 2(0) - 1/2

y = - 1/2

At y = 0, the value of the variable 'x' will be given as,

0 = 2x - 1/2

2x = 1/2

x = 1/4

The x-intercept and y-intercept of the line are at (0, -1/2) and (1/4, 0). Then the correct option is C.

At Open Skate Night, admission is $3.75 with a membership card and $5.00 without a membership card. Skate rentals are $3.00. The Moores paid $6 more for skate rentals than the Cotters did. Together, the two families paid $42 for skate rentals. How many pairs of skates did the Moores rent? The Moores rented 9 pairs of skates.

Answers

Answer: 8 skates

Step-by-step explanation:

Given that:

Skate rental = $3

Let number of skates rented by cotters = x

Hence, amount paid by cotters = 3x

The Moores paid $6 more

Moores amount = 3x + 6

Combined amount paid = 42

3x + 3x + 6 = 42

6x + 6 = 42

6x = 42 - 6

6x = 36

x = 36 / 6

x = 6

Hence, amount spent by the Moore's:

3x + 6

3(6) + 6 = 18 + 6 = $24

Cost per skate rental = $3

Hence x number of skates rented by the Moore's = $24 / 3 = 8 skates

Given :

Duc and Hue baked cookies to help with their community's fundraiser. Duc baked 10 less than twice the number of cookies Hue baked. Together they baked 80 cookies.

The following steps can be used in order to determine the system of equations models given situation:

Step 1 - Let the total number of cookies Duc baked be 'd' and the total number of cookies Hue baked be 'h'.

Step 2 - The linear equation that represents the total number of cookies Hue and Duc baked is:

d + h = 80

d = 80 - h  --- (1)

Step 3 - The linear equation that represents that Duc baked 10 less than twice the number of cookies Hue baked is:

d = 2h - 10  --- (2)

Step 4 - Substitute the value of 'd' in equation (2).

2h - 10 = 80 - h

Step 5 - Simplify the above expression.

3h = 90

h = 30 cookies

Step 6 - Substitute the value of 'h' in equation (1).

A microbiologist is growing bacteria cultures in the lab. After 5 minutes, a bacteria colony has 1.3 million organisms. After 12 minutes, the same colony has 41.5 million organisms. After 15 minutes, the colony has grown to 101.3 million organisms. Is this a proportional or non-proportional relationship?

Answers

Answer: Non proportional

Step-by-step explanation:

To know if the values given are proportional or not, we will use the formula:

y = kx

where

y = number of organisms

x = number of minutes

k = constant of proportionality

After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx

1,300,000 = 5k

k = 1,300,000 / 5

k = 260,000

After 12 minutes, the same colony has 41.5 million organisms. Using y= kx

41,500,000 = 12x

x = 41500000 / 12

x = 3458333.8

After 15 minutes, the colony has grown to 101.3 million organisms.

y = kx

101,300,000 = 15k

k = 101,300,000 / 15

k = 6753333.8

It is a non-proportional relationship as the constant of proportionality is different for each.
