The area of a triangle:
A_\Delta=\dfrac{bh}{2}
We have:
A_{\Delta}=234.4\ ft^2.\\\\h=16\ ft.
substitute:
\dfrac{16b}{2}=234.4\\\\8b=234.4\ \ \ |:8\\\\b=29.3\ ft.
Answer: 29.3 ft.

In a certain quiz that consists of 10 questions, each question after the first is worth 4 points more than the preceding questio
weqwewe [10]

Answer:

C. 26

Step-by-step explanation:

Let’s suppose that the first question is worth ‘’x’’ amount of points. Then the second question will be worth x+4, the third question x+8, the fourth question x+12, the fifth x+ 16, the sixth x+20, the seventh x+24, the eighth x+ 28, the ninth x+ 32, and the last one x + 36.

The sum of the points of all these questions is equal to 10x + 180. Since the quiz has a total of 360 points, then

10x + 180 = 360.

Solving for x we get:

X = 18.

This means that the first question is worth 18 points, the second one 22 points (18 +4), the third one 26 points(18+4+4), and so on.
