18 is 36% of 50.

<u>Solution: </u>

Need to determine what percent of 50 is 18.

Let's assume x % of 50 is 18.

x % can be written in fraction as \frac{x}{100}

Hence  x % of 50 is written as,

\frac{x}{100} \times 50=18

\begin{array}{l}{\Rightarrow \frac{x}{2}=18} \\ {\Rightarrow x=18 \times 2=36 \%}\end{array}

So 18 is 36% of 50.

This can also be determined by another method.

18 out of 50 can also be written as 18/50

Percentage is equal to numerator when denominator is 100.

So we need to find equivalent rational number of \frac{18}{50} where denominator = 100

On multiplying numerator and denominator by 2 we get

\frac{18 \times 2}{50 \times 2}=\frac{36}{100}=36 \%

Hence 18 is 36% of 50.

Which expression is equivalent to t2 – 36?
defon

Answer:

(t + 6)(t - 6)

Step-by-step explanation:

(t - 6)(t + 6)

(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)

= t² - 6t + 6t - 36

= t² - 36

so,

t² - 36 = (t + 6)(t - 6)

Which equation represents the line passing through the points (4, −1) and (1, 0)? Select one: A. x + 3y = 1 B. 3x + y = 1 C. x −
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

Gradient of a line =( y2 - y1)/x2 - x1

From the question, x1=4,y1=-1,x2=1,y2=0.

Therefore, substitute for these values in the above formula

m = 0-(-1)/1-4

= 0+1/-3

= -1/3.

Therefore, y-y1/x-x1 = -1/3

y - y1 = -1/3(x - x1)

y - (-1) = -(x-x1)/3

y+1 = - (x - 4)/3

Multiply through by 3

3y+3= -x+4

3y +x=4-3

x+3y= 1

Therefore the answer is A.
