Answer:part a=4.6 part b=2.6
Step-by-step explanation:part a= first make sure to know which direction is which next you would end up making a triangle with the legs as 1.7 and 4.3 and use pythagorean theorem a^2+b^2=c^2 so 1.7^2 + 4.3^2= c^2 1.7^2=2.89 4.3^2=18.49 2.89+18.49=21.38 so now you square root 21.38 to get 4.62385 so it equals 4.6
part b = is basically the same thing except they gave you 3.1 as c and 1.7 as a so you would put it as c^2 - a^2=b^2 so 9.61 - 2.89= 6.72 then square root it to get 2.592296 which means it equals 2.6
Answer:
(a^2)+4a-5
Step-by-step explanation:
(3+a+2)(a+2-3)
(a+5)(a-1)
use FOIL or box method
5a-5+(a^2)-a simplifyes to
(a^2)+4a-5
Answer:
divide 64/8 and 27/9 to arrive at 8/3 for 64/27
Answer:
54 Pounds
Step-by-step explanation:
We know that they start off with 67.5 pounds of sugar and they need to reduce it by 20%. We also know from the problem that we want to know the MAXIMUM amount of sugar consumed by each track member.
The typical high school student consumes about 67.5 pounds of sugar per year. That is our first piece of the problem
67.5
We now know that 20% of it needs to be reduced. This means that we can multiply it by 0.8 because that is 20% less than 100% of the sugar.
67.5 x 0.8
This leads the answer to be 54 Pounds
Hope this helped :D
Answer:
8 cm and 9 cm
Step-by-step explanation:
The other two sides added together have to equal a larger number than 13, since 13 is the largest side.
5 + 8 = 13
6 + 7 = 13
7 + 2 = 9
8 + 9 = 17
