2 answers:
Answer:
there are 10 blue marbles in the bag
Step-by-step explanation:
A bag contains 60 marbles, some blue and some green. The ratio of blue marbles to green ones is 1: 5.
Total of 60 marbles
The ration of blue to green is 1:5
1+5 = 6
Total of 6 marbles , 1 is blue
now we make a proportion. Let x be the number of blue marbles in the bag
Cross multiply it
Divide both sides by 6
x=10
So there are 10 blue marbles in the bag

XY = 17.
Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.
It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus,
To solve this equation, square and add both of the terms on the right like this:
And then take the square root of both sides. Your final answer should be:
XY = 17.
