Answer:

B

Step-by-step explanation:

Area of a trapezoid = (1/2)*(base1+base2)*height

Area = (1/2)*(15+7)*height

DC is 7 which means EF is also 7.

AB = 15

AB - EF = AE + FB = 8

And AE = FB we know that AE is 8/2 = 4

We were given AD = 5. We have a 3-4-5 right triangle and therefore DE is 4. The height of the trapezoid is 3 ft.

Area = 1/2 (15+7)*(3)

Area = (1/2)*22*3

Area = 11 * 3

Area = 33 ft^2

Your answer is B

<h3>Answer:</h3>
  1. C. (9x -1)(x +4) = 9x² +35x -4
  2. B. 480
  3. A. P(t) = 4(1.019)^t

Step-by-step explanation:

1. See the attachment for the filled-in diagram. Adding the contents of the figure gives the sum at the bottom, matching selection C.

2. If we let "d" represent the length of the second volyage, then the total length of the two voyages is ...

... (d+43) + d = 1003

... 2d = 960 . . . . . . . subtract 43

... d = 480 . . . . . . . . divide by 2

The second voyage lasted 480 days.

3. 1.9% - 1.9/100 = 0.019. Adding this fraction to the original means the original is multiplied by 1 +0.019 = 1.019. Doing this multiplication each year for t years means the multiplier is (1.019)^t.

Since the starting value (in 1975) is 4 (billion), the population t years after that is ...

... P(t) = 4(1.019)^t

What is greater 16/25 or 65%
slega [8]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

65% has the greater value.  

»»————- ★ ————-««  

Here’s why:  

  • We can convert both numbers into decimals and then compare the values.

⸻⸻⸻⸻

\boxed{\text{Comparing Numbers:}}\\\\-------------\\\rightarrow\frac{16}{25}= 0.64\\\\\rightarrow 65\%=\frac{65}{100}=0.65\\ -------------\\\\\boxed{0.65 > 0.64}\\\\\text{Therefore:}\\\\\boxed{65\% > \frac{16}{25}}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
