Answer:

The ratio of the number of gigabytes to the price in dollars for Dial It Up is 1:8

The ratio of the number of gigabytes to the price in dollars for Ring Ring is 1:9

Step-by-step explanation:

The word problem relates to the comparison between the cost of a gigabyte on Dial It Up network and the cost per gigabyte on Ring Ring network

On Dial It Up, 2 gigabytes costs $16

Therefore, 1 gigabytes costs $16/2 = $8

Which gives Dial It Up cost per gigabyte as $8 per gigabyte

On Ring Ring, 1 gigabytes costs $9

Which gives Ring Ring cost per gigabyte as $9 per gigabyte

The ratio of the number of gigabytes to the price in dollars for Dial It Up is 1:8

The ratio of the number of gigabytes to the price in dollars for Ring Ring is 1:9.

In a pen of goats and chickens, there are 40 heads and 150 feet. How many goats and chickens are in the pen?
s2008m [1.1K]

Hey there!!

A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet

For heads, total = 40

Let us take the number of chickens as ' x ' and goats as ' y '

x + y = 40 ------------- ( 1 )

2x + 4y = 150 ----------- ( 2 )

Multiply the first equation with 2

2x + 2y = 80

2x + 4y = 150

Subtract the first equation from the first

2y = 70

y = 35

Number of goats = 35

substitute this in other equation

x + y = 40

x + 35 = 40

x = 5

Number of chickens are 4

Hope it helps!

Please someone help me with this!
Olenka [21]

Answer:

<u>Please read the answer below.</u>

Step-by-step explanation:

<u>Question 2. 25% of what number is 30?</u>

25% - Whole 30, 50% Whole 60, 75% Whole 90, 100% Whole 120

<u>Question 3. What operation did you use the find the whole?</u>

In the previous question, I found the whole, adding 30 to the previous value.

For example, I added 30 to 30 and calculate 60. To 60 then i added 30 to get 90 and added 30 to get 120 because in this question, all the 4 parts were exactly the same size (30).

<u>Question 4. What are you multiplying/dividing? Do you use the percent or something else?</u>

In the specific case of question 2, I noticed that the size of the parts were exactly the same, using it for calculating the whole. If 1 part out of 4 is 30, then 2 parts or 50% are 60, 3 parts or 75% are 90 and then 4 parts of 100% are the whole I'm being asked, in this case, 120.

2/3 to 8 in simplest form
Nat2105 [25]
2/3 to 8 is the same ratio if we multiply both sides by 3/2 so:
2/3×3/2=1
8×3/2=12
So 1 to 12
