At the beginning of a baking session, there were 2.26 kilograms of flour in a bag. By the end of the baking session, there were

Arisa [49]

Answer: 56.64%

Step-by-step explanation:

Given: Previous amount of flour = 2.26 kilograms

By the end of the baking session, amount of flour = 0.98 kilograms

Decrease in amount = 2.26-0.98 = 1.28 kilograms

Percent decrese = $\dfrac{\text{decrease in amount }}{\text{previous amount}}\times100$

$=\dfrac{1.28}{2.26}\times100\approx56.64\%$

Hence, the percent decrease in the amount of flour = 56.64%

Determine if the table shows a proportional relationship.

swat32

The ratios of y over x are all equal to 1/3, thus we may infer that: B. the table is proportionate.

What is a Proportional Relationship?

Any pair of values in a table that depicts a proportionate relationship have the same value for the proportionality constant, k, where k = y/x.

Check each pair of values in the table to see if k is the same:

(36.75, 12.25):

k = 12.25/36.75 = 0.33

(16.8, 5.6):

k = 5.6/16.8 = 0.33

(77.1, 25.7):

k = 25.7/77.1 = 0.33

It is proportionate because the ratios of y across x are all equal to 1/3, which implies that the value of k is identical for all values.

Juliette [100K]

Answer:

At 15:15

Step-by-step explanation:

Given,

the 1st boy can run a lap in 15 minutes

the 2nd boy can run a lap in 25 minutes

the 3rd boy can run a lap in 10 minutes

Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.

$L.C.M.$ of 15,25 & 10 = 150

So,they will pass each other after 150 minutes or 2 hours & 30 minutes.

If we add it with 12:45 we'll get 15:15 or 3:15 pm
