Here the triangles are similar. SO we have to use the similarity property, which is:
Corresponding sides are in same proportion, that is
6/12 = PQ/18
Performing cross multiplication,
12PQ = 18*6
Dividing both sides by 12
PQ = 9
Correct option is the last option .
I know only how to solve one, using the Pythagorean theorem, you have to square 45
Which is
45^2 - 25^2 = 1400
Now you multiply 37.42 x 37.42 which gets you 1400.2564
I’m in 8th grade by the way
2.48 / 0.4
Multiply both top and bottom by 10
(2.48 * 10) / (0.4 * 10)
24.8 / 4
6.2
Hope this explains it.
Answer:Suppose the cost stock is x and the cost of fund is y.
Total cost of Nora's portfolio:
100x+200y=3800.....i
Total cost of Erin's portfolio
300x+50y=5350...ii
solving the simultaneous equation by elimination method we proceed as follows:
multiplying eqn by 3 and subtracting ii we get:
550y=6050
thus
y=6050/550
y=11
next, multiply ii by 4 and subtracting i we get:
1100x=17600
x=16
thus the cost of Technology stock was $16 and the cost of mutual fund was $11
