Arrange the zoo animals from greatest to least according to their weights. elephant: 5.5 × 103 kilograms giraffe: 1.6 × 103 kilograms lion: 1.9 × 102 kilograms bengal tiger: 2.2 × 102 kilograms giant panda: 1.2 × 102 kilograms

Elephant (5,500 kg), giraffe (1,600 kg) bengal tiger (220 kg), lion (190 kg), giant panda (120 kg).

Step-by-step explanation:

1. The weights of the zoo animals given in the problem are written in scientific notation form.

2. You can rewrite the weights as following:

Elephant:

Giraffe:

Lion:  

Bengal tiger:  

Giant panda:  

3. Arranging the animals from greastest to least according their weights:

Elephant, giraffe, bengal tiger, lion, giant panda.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
