Beverage A and Beverage B are sold in identical cans. Beverage A is 6% sugar. The portion of Beverage B that is sugar is 0.21. H
muminat

Answer:

3.5 more times sugar in B

Step-by-step explanation:

We need to see that the fact that Beverage B is 0.21 sugar can be translated to percentages, just by multiplying and dividing by 100 to get it easier to see:

0.21 * 100 /100 =  21/100 = 21% percent

This means that for every 100 units, 21 are sugar.

Now we can compare percentages directly, as both have the same volume because are sold in identical cans. We need to get how many times is 21 greater than 6. The only thing we need to do is the ratio between them:

21/6= 3.5

This implies that 21 is 3.5 greater than 6, you can verify it by multiplying 6 by 3.5 and getting 21.

So, B has 3.5 times more sugar than A.

mihalych1998 [28]

Answer:

Step-by-step explanation:

Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.

In the selected box 18 good mangoes and 2 damaged mangoes are there

a) Find the probability that the first mango is not damaged.

= prob of selecting 1 from any one of 18 good mangoes = \frac{18}{20} =0.90

b. Find the probability that neither of the mangoes is damaged. =

Prob of selecting 2 from 18 good mangoes

=\frac{18C2}{20C2} =0.5276

c. Find the probability that both mangoes are damaged.

= Prob of selecting 2 from 2 bad mangoes

=\frac{2C2}{20C2} =0.005263

That converse theorem is
.. "If a line divides two sides of a triangle proportionally, then it is parallel to the third side."

_____
It seems you're supposed to remember that the theorem involves parallel lines, not perpendicular ones.
