Answer:
Option C.
Step-by-step explanation:
Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.
Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.
Using triangle proportionality theorem we get
On cross multiplication we get
Divide both sides by 9.
The length of SA is 3ft.
Therefore, the correct option is C.
2.75=2 3/4 because you would say 2.75 as two and seventy-five hundredths. Seventy-five hundredths is just like 3 quarters out of 4 because 1 quarter=25. 2=50. 3=75. So, 2.75 as a fraction in simplest form is 2 3/4.
Hope I helped:D
31 i hope u got it right !!
X2 + 14X = -49
+49
x2 + 14X + 49
(x2 + 14X + 7) + 49 - 7 = 0
(X+7)2 + 42 = 0
- 42
(x+7)2 = 42
*square root of both sides)
X + 7 = square root of 42
-7
X = -7 +/- square root of 42
x = -13.48
x = -0.52
and for b, without doing any work my guess is because there is a 0 under the radical, which gives you only one real solution
Talk to as many people as you can and be nice. It also helps if you are helpful to people, but try not to get too stressed out. Always focus on school.
