Answer 1

Answer: Alright, since you know the two shapes are similar, this means the scaling ratios are the same, and all sides will produce the same fraction when compared to one another, e.i : LK to BA. You start by making a fraction of the two sides with lengths you know, giving you the fraction 10/3 from BA to LK. Then by cross multiplying in the equation below you get the answer of :

10/3= 4/y to 10y=12. then by dividing by 10 you get the answer of 1.2 cm or A

Of the 25 sheep in the flock 34% are white.what is the total number of white sheep in the flock

Answers

Convert 34% into decimal - 0.34

Multiply 25 by 0.34 which is 8.5

Since you can’t have half a sheep, 8 is the total number of white sheep.

Katherine and Shelly had $288 altogether. Katherinine gave 1/3 of her share to Shally and their father gave $68 to Shally. They now have the sme amount ofMoney. How
Much money did
Shally have at first?

Answers

This is a problem that has to be read minutely to understand the tricks inside it.
Amount of money Catherine and Shelly had altogether = $288
Now Katherine gave 1/3 of her share to Shelly.
Let us assume the amount of money Katherine had = x
Amount of money Katherine gives to Shelly = x/3
The amount of money given by their father to Shelly = $68
Then
Amount of money that Katherine now has = [(x/3) + 68]
Now we can easily get to the equation
x = [(x/3) + 68]
3x = x + (68 * 3)
3x - x = 204
2x = 204
x = 204/2
= 102
So the amount of money that Katherine has = $102
Amount of money Shelly had at first = x/3
= 102/3 dollars
= 34 dollars
So Shelly at first had $34 with her.

I'm curious as to how a wrong answer can be a "verified answer." What is BRAINLY's process for verification?

You can see an error in the "verified answer" here:

"Amount of money that Katherine now has = [(x/3) + 68]"

No. If X is the amount of money Katherine had, and she gave away 1/3, then she has 2/3(x). And the +68?

Shelly's dad gave that $68 to Shelly, not to Katherine.

The answer my son and I came up with was $21. We used bar models since they aren't teaching 2-variable algebra in 5th grade. But here's the logic.

We know what Katherine and Shelly collectively now have $356 ($288 + $68 from the dad).

They have equal amounts now, so they each have $178. Half of that is $89, which is significant since we need to find the value of the "thirds" that constitute Katherine's original amount. She has two of those thirds left and each of the two is worth $89 (half of what she has now). This is really where the bar model method helps to visualize, by the way.

Now we now how much Katherine gave Shelly: $89 (same value as each of the other two, equal thirds of Katherine's original amount).

If we know that the $178 Shelly has now is made up from the $89 that Katherine gave her, plus the $68 her dad gave her, plus whatever mystery amount she started with, we can do $178 - ($68 + $89) and get $21.

Let's verify this answer right here:

Katherine started with $267 and Shelly started with $21.

Katherine gave Shelly $89 (1/3) of her money.

Katherine now has $178 ($267 - $89) and Shelly now has $110 ($21 + $89).

Shelly's dad gave her another $68. Now they both have $178.
