Answer:
There are 144 blue marbles out of the 188 total.
Step-by-step explanation:
We know that in the bag, there are 188 total marbles. We are given the percentage of how many are blue out of the 188 total marbles. You can simply take the given fraction, and convert it to a percentage of 75%. This can also be expressed as a decimal: 0.75. When you multiply the total amount by the percentage, you can find the amount of marbles that are blue. So, 188 * 0.75 = 141. There are 141 blue marbles out of the total of 188 marbles. And to check, notice that the original fraction quite literally means for every 4 marbles there are 3 that are blue, which is 3 blue/4 marbles which = 0.75. So, if we apply our new numbers, we get 144 blue/188 marbles = 0.75, just like the original percentage. This is how we know that the correct number of blue marbles is 144. Cheers!
Answer:
Both are right triangles. That means they both have a 90∘ angle. They also both have a 30∘ angle.
It follows that both triangles have a 60∘ angle:
180∘−90∘−30∘=60∘.
So they have three angles in common.
The triangles are CONGRUENT as per the AAA rule of congruency.
