It is B because 40x32=1280 and 5x4=20 then divide 1280 by 20 and you get 64 but you can’t have 64 so you would need to only have 60 so the answer is B

Can someone explain how I'm supposed to determine whether each pair of ratios form a proportion? I so stuck on it sorry can i ge

Natalka [10]

Step-by-step explanation:

We will learn how to solve proportion problems. We know, the first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means.

Therefore, in a proportion, product of extremes = product of middle terms

example

1. Check whether the two ratios form a proportion or not:

(i) 6 : 8 and 12 : 16; (ii) 24 : 28 and 36 : 48

Solution:

(i) 6 : 8 and 12 : 16

6 : 8 = 6/8 = 3/4

12 : 16 = 12/16 = 3/4

Thus, the ratios 6 : 8 and 12 : 16 are equal.

Therefore, they form a proportion.

8. Line AB passes through A(-2,4) and B(-8,-6).

netineya [11]

Answer:

AB : $\frac{5}{3}$

PT : $-\frac{1}{5}$

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be $\frac{4-(-6)}{-2-(-8)} =\frac{5}{3}$ (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be $\frac{-1-(-2)}{3-8} =-\frac{1}{5}$ . (Answer)

Here we have applied the formula of slope of a straight line passing through the points $(x_{1},y_{1})$ and $(x_{2},y_{2} )$ as given by $\frac{y_{1}-y_{2} }{x_{1}-x_{2} }$ .
