The ratios are all proportional to 50/1.

Ratios are proportional when its cross products are equal.
a/b = c/d where ad = cb

100/2 is proportional to 50/1 because 100*1 = 2*50 ⇒ 100 = 100
150/3 is proportional to 50/1 because 150*1 = 3*50 ⇒ 150 = 150
175/3.5 is proportional to 50/1 because 175*1 = 3.5*50 ⇒175 = 175
200/4 is proportional to 50/1 because 200*1 = 4*50 ⇒ 200 = 200

astraxan [27]

Answer:

25.375 ounces

Step-by-step explanation:

To find the weight of the largest shirt size, we need to find the value that is 1 3/4 times as much as the smallest shirt size. To do this, we need to multiply the two numbers (14.5 x 1 3/4). In order to make this process easier, we can convert 1 3/4 into a decimal, which would be 1.75. After that, we just multiply; 14.5 x 1.75 = 25.375. Your answer is 25.375 ounces.

Answer:

x = .06418

Step-by-step explanation:

2 + (9.2)−8x = 2.32

(9.2)−8x = 2.32 − 2

log (9.2)−8x = log .32

−8x log 9.2 = log .32

−8x log 9.2

−8 log 9.2

=

log .32

−8 log 9.2

x = .06418
