Answer:
Onaje is correct.
Step-by-step explanation:
To start, total up how many shirts we have, and multiply them by <em>t</em>. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25<em>t</em>, making Onaje's expression correct.
EDIT: Just saw you need why it's incorrect for Paula, just hold on.
So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.
Hope this helps.
Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.
The decrease is 2.7% which is written as 0.027 as a decimal.
Subtract that from 1:
1 - 0.027 = 0.973
The multiplier would be 0.973
The answer would be B. Only 3.
An object has a line of symmetry when it is cut a certain way and both parts are identical. Only line 3 will give you two identical halves when cut in that way.

Answer:
Answer is
sine = 0.769
cosine = 0.6389
Step-by-step explanation:
Given a right angle triangle
Where Height of triangle = 10
And Hypotenuse of triangle = 13
Then, we know Sin Ф = Height/ hypotenuse
or SinФ = 10/13
or Ф = arcsin (10/13)
or Ф = 50.285°
So , sin Ф = sin 50.285° = 0.769
Next we need to cosine.
i.e cos Ф = cos 50.285° = 0.6389
Hence we got, sine = 0.769
And cosine = 0.6389
