Answer:

Andre drank 13.52 fluid ounces

Step-by-step explanation:

To find this answer, we need to multiply the volume of the bottle (16.9) times 0.8 to find the answer. This is because to find the percentage, move the decimal to the left twice for the percent and then multiply that number by the other amount to get the answer. of 13.52 fluid ounces.

In the figure below, determine the perimeter of triangle EFG
Airida [17]

Answer:

82 units

Step-by-step explanation:

From the image, we can see that the 2 triangles are similar triangles.

Thus:

BC = EF

BD = EG

CD = FG

Now, BD = 4x - 9 and EG = 2x + 15

Thus;

4x - 9 = 2x + 15

4x - 2x = 15 + 9

2x = 24

x = 24/2

x = 12

Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39

Also, EF = BC = 17

FG = 26

Thus, perimeter of triangle EFG is;

P = 26 + 17 + 39

P = 82 units

Simplify −0.6(−6.3) answer??
Leno4ka [110]
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put 
    0.6
 x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]

I'm sorry if it was confusing, I hope it helped!
