15 cookies burned. 3/4 Is equal to 75% so you want to take 75% of 20. OF always mean multiply, but first we divide by 100 to get it into a decimal so 0.75 X 20 equals 15 (if you punch into calculator) so only 5 cookies are not burned. but the 3/4 that for burnt were the other 15

What theorem can be used to prove the 2 triangles similar?
ASHA 777 [7]

Answer:

C. SSS

Step-by-step explanation:

\frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2

Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.

Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.

Select the correct answer from the choices given (13 4i) n = 0 what is n? 0 1 –13 4i –13 - 4i
Artemon [7]

The correct answer from the choices given will be -13 - 4i. The numerical part is the real number while the term containing i is the imaginary part.

<h3>What is the complex number?</h3>

A complex number is one that both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.

The given complex number as;

\rm 13 + 4 i + n =0

By transfeering the left-hand side term to the right-hand side the sign will change. We will get the value of n as;

\rm n=-13 - 4i

Hence the correct answer from the choices given will be -13 - 4i.

 Find 5 consecutive whole numbers if it is known that the sum of the squares of the first 3 numbers is equal to the sum of the
Sloan [31]
So... our numbers... let's say the first one is hmmm "a"
so the second and subsequent are
a
a+1
a+2
a+3
a+4

there, 5 consecutive whole numbers or integers for that matter

now, we know the sum of the square of the first three,
is the same as the sum of the square of the last two

so \bf \begin{cases}&#10;a\\&#10;a+1\\&#10;a+2\\&#10;\textendash\textendash\textendash\textendash\\&#10;a+3\\&#10;a+4&#10;\end{cases}\qquad (a)^2+(a+1)^2+(a+2)^2=(a+3)^2+(a+4)^2

do a binomial theorem expansion on those, solve for "a"
