Answer:
15.71
Step-by-step explanation:
Length AB = sqrt ( (3-3)^2 + (2- - 1)^2) = sqrt9 = 3
Length BC = sqrt ( (-3-3)^2 + ( -1-2)^2) = sqrt 45
Lemgth CA = sqrt( 6^2) + (-1 - -1)^2 = sqrt 36 = 6
Perimeter = 3 + 6 + sqrt45
= 15.71
Answer:
Cork: Less
Wood: About the same
Metal: More dense
Step-by-step explanation:
Whether or not a block floats inside water is dependent on its density. If it is floating, it means it has a lower density. If it is sinking, it means it has a higher density. If it has the same, it will be half under and half over.
Mathematically, specific gravity can be used to support this phenomenon.
*In this context, water is our reference and the blocks are our substances.
Since Boyancy force can be described 
(the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
On the number line after 10 moves frog is at the integer -96.
Given that, a frog starts at 0 on a number line.
It jumps 100 units to the right then jumps 200 units to the left=+100-200=-100 (2 moves).
It then jumps 199 units to the right followed by 198 units to the left =-100+199-198=-99 (2 moves).
It then jumps 197 units to the right followed by 196 units to the left =-99+197-196=-98 (2 moves).
It then jumps 195 units to the right followed by 194 units to the left =-98+195-194=-97 (2 moves).
It then jumps 193 units to the right followed by 192 units to the left =-97+193-192=-96 (2 moves).
Hence, on the number line after 10 moves frog is at the integer -96.

The antelope is faster than the wildebeest.
Step-by-step explanation:
The maximum recorded speed for the antelope is 88.5 km/h that it can sustain for almost a kilometer.
The equation for distance a wildebeest can run in t hours is given as ;
d=80t
Assume t=1 hour,d=80*1=80 km then you can say the wildebeest takes 1 hour to cover 80 km and 80 km/h
For a distance of 80 km, the antelope will take how many hours;
Time =Distance/speed =80/88.5 =0.904 hours
The antelope takes less hours to cover the distance, hence the antelope is faster than the wildebeest.

Answer:
Crops are genetically modified to allow higher yields due to the production of molecules that are toxic to insect pests, but have no effect on animals and humans. ... Crops that are resistant to herbicides can also provide higher yield as the farmer can reduce the number of competing weed species in the field.
