Answer:
4,784
Step-by-step explanation:
Find how many are defective
Convert 8% to a decimal
8/100=0.08
Multiply
5,200*0.08=416
416 are defective, to find how many aren't subtract the defective from the whole
5,200-416=4784
So, 4,784 are not defective
Hope this helps! :)
Answer:
PSQ and RSP
Because both of them have a 90 angle at S because given that PS is perpendicular to QR
Which is an A postulate
Then
Part 3 in attached file
Hope u understand
We have three similar triangles, let's see if we can get this right, right vertex first, then other vertex from small side:
EDF ~ GDE ~ GEF
As ratios that means
ED:DF:EF = GD:DE:GE = GE:EF:GF
x:20:y = 5:x:GE = GE:y:15
Since we're after y we choose
20/y = y/15
20(15) = y²
y² = 300
y = 10√3
y ≈ 17.32
Answer:
33.8
Step-by-step explanation:
1) Use Phythagoras theorem to get RS ↓
2) RS = RQ
therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓
Hope this helps =)
