The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3
When do two ratios form a proportion?Two ratios form a proportion if the simplified form of both ratios comes out as the same ratio. Suppose that we've got two quantities with measurements as 'a' and 'b' Then, their ratio(ratio of a to b) a:b
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.
A.) 22/33 and 14/21
Here. the two ratios represent quantities that are proportional to 1/3.
B.) 48/60 and 35/42
Here. the two ratios represent quantities that are not proportional.
C.) 25/28 and 5/7
Here. the two ratios represent quantities that are not proportional.
D.) 16/13 and 13/16
Here. the two ratios represent quantities that are not proportional.
Hence, The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26
Answers

Step-by-step explanation:
1 / 3 (x - 2) = 1 / 5 (x + 4) + 2
1/3x - 2/3 = 1/5x + 4/5 + 2
1/3x - 1/5x = 4/5 + 2/3 + 2
(5x - 3x)/15 = (12 + 10 + 30) / 15

John went on a bike ride to the store 4 miles away. If it took 3/10 of and hour to get there and 1/2 of an hour to get back, what was his average rate of speed for the entire trip
Answers
Answer:
10mph or 10 miles per hour
Step-by-step explanation:
From the question,
John ride 4 miles to the store and 4 miles back
Total distance travelled = 4 miles + 4 miles
= 8 miles
Total time travelled
Time to the store = 3/10 of an hour
Time back from the store = 1/2 of an hour
Total time travelled
= 3/10 + 1/2
= (3 × 2) +(10 × 1)/20
= 6 + 10/20
= 16/20
= 4/5
Total time travelled= 4/5 hour
His average rate of speed for the entire trip formula =
Speed = Total distance travelled (miles)/ Time (hour)
= 8/(4/5)hour
= 8 ÷ 4/5
= 8 × 5/4
= 40/4miles/ hour
= 10 miles/ hour
Therefore, his average rate of speed for the entire trip is 10 miles/hour

Toby is packaging 21 baseball cards and 12 football cards to sell at the swap meet. Each packet will have the same number of cards. Each packet will have the cards for only one sport. What is the greatest number of cards you can place each packet? How many packets would it be for each sport?
Answers
Answer: The greatest number of cards you can place each packet = 3
There would be 7 packets of baseball cards and 4 packets of football cards.
Step-by-step explanation:
Given: Number of baseball cards =21
Number of football cards = 12
Each packet will have the same number of cards.
Each packet will have the cards for only one sport.
Then, the greatest number of cards you can place each packet = GCD (21,12) i.e. greatest common divisor of 21 and 12
Since 21 = 3 x 7 and 12 = 2 x2 x3
so, GCD(21, 12)=3
So, the greatest number of cards you can place each packet = 3
Number packets of baseball cards = [tex]\dfrac{21}{3}=7[/tex]
Number packets of football cards = [tex]\dfrac{12}{3}=4[/tex]
So, there would be 7 packets of baseball cards and 4 packets of football cards.

Answers
=========================================================
Let's go through the answer choices one by one
A) This is false because parallel lines do not cross or intersect. They cannot have a point in common.B) This is false because lines need to cross in order to form a right angle. C) This is true. Parallel lines never intersect. They are the same distance away from one another at any point along either line. One example of parallel lines are the metal tracks in a railroad.D) This is true. Having a point in common means a point is on both lines at the same time, but parallel likes never cross. So they have no points in common.(QUICK RESPONSE!)
