Are these ratios equivalent? 18 : 45 and 2 : 6

Answers

Answer:

No, six multipled by nine is not 45

Step-by-step explanation:

Happy holidays

No, the given ratios 18 : 45 and 2 :6 are not equivalent.


Are these ratios equivalent? 18 : 45 and 2 : 6, To be justified.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Example 9 / 4 , 4 / 8 , 9 : 2 , a : b ratios of volumes,  volume of cirlce : volume of square.

Here,
18 : 45 = 18 / 45
=18 / 45
18 and 45 have common lowest multiple of 9 so
= 2 * 9 / 5 * 9
= 2 / 5
Here, 2 / 5 is not equivalent to 2 / 6 so it would be said that 18/45 is not the equivalent ratio to 2 : 6.

Thus, No, the given ratios 18:45 and  2 : 6 are not equivalent.

Answer:

8) the ordered pair is a solution, 9) the ordered pair is not a solution

Step-by-step explanation:

8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair

9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair

Answer:

8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16

9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal

PLEASEEEEE HELPPPP MEEEE!!!! There are 5 friends who decide to split an 88- ounce bag of popcorn. If they split it evenly, how many ounces of popcorn will each friend get?
Solution:

Number Model:

Explain what you did with the remainder and why.

Answers

Answer:

17.6 ounces (U.S.) and or 2.2 cups (U.S.)

Step-by-step explanation:

88 ounces divided by 5 equals 17.6 ounces

88 / 5 = 17.6

The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn

If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it

*Side note: 8 ounces is 1 cup

Answer:

17.6 ounces (U.S.) and or 2.2 cups (U.S.)

Step-by-step explanation:

88 ounces divided by 5 equals 17.6 ounces

88 / 5 = 17.6

The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn

If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it

The town recreation department ordered 100 balls and bats for the summer baseball camp. Balls cost $4.50 each, and bats cost $20. 00 each. They spent $822.00 . How many of each item, bats and balls, were purchased.

Answers

Answer:

76 balls and 24 bats

Step-by-step explanation:

Set up a system of equations where x is the number of balls and y is the number of bats:

x + y = 100

4.5x + 20y = 822

Solve by elimination by multiplying the top equation by -20, then combine the equations together:

-20x - 20y = -2000

4.5x + 20y = 822

-15.5x = -1178

x = 76

Then, plug in 76 as x in the first equation to solve for y:

x + y = 100

76 + y = 100

y = 24

So, 76 balls and 24 bats were purchased.
