What is 55 percent of 160?
Maurinko [17]

Answer: 88

Step-by-step explanation: To find 55% of 160, first write 55% as a decimal by moving the decimal point two places to the left to get .55.

Next, the word "of" means multiply, so we have (.55) x (160).

(.55) (160) = 88

Therefore, 55% of 160 is 88.

Hunter-Best [27]

Answer:

Option (C)

Step-by-step explanation:

Given:

In right triangles ΔAED and CEB,

m∠AED = m∠CEB = 90°

DE ≅ BE

AD ≅ BC

To prove:

ΔAED ≅ ΔCEB

                    Statements                         Reasons

1). m∠AED = m∠BC = 90°              1). Given

2). DE = BE                                     2). Given

3). AD = BC                                    3). Given

4). ΔAED ≅ ΔCEB                          4). By HL theorem of congruence

Option (C) is the answer.

I need some help on number 15 please...
kondaur [170]
To solve this problem, all you need to do is make a standard graphing equation. The first step is finding mode using two points from the table. We'll use (1, 70) and (2, 90).
\frac{y_{1}- y_{2}  }{ x_{1}- x_{2}}  \\  \frac{70-90}{1-2}  \\  \frac{-20}{-1}  \\ 20
From the work, we've found that the slope of this equation is 20.

Next, we need to finish writing the equation and plug in the coordinates to solve for the y-intercept.
y=20x+b \\ 90=20(2)+b \\ 90=40+b  \\ (90)-40=(40+b)-40 \\ b=90-40  \\ b=50

Now we have all the information we need to write our equation, which is:
y = 20x+50

Hope this helps!
