Answer: 4 pancakes
Step-by-step explanation: because 30min÷6pancakes=5
So, 20min÷5=4
Answer:
5/6
Step-by-step explanation:
2 1/2 -> 5/2
5/2 divided by 3, which is 0.83333333333
0.83333333333 as a simplied fraction is 5/6
Sum of angles In all triangles are 180....line DAC is horizontal and therefore is 180 degrees ....so minus 180 degrees from 105 and you get 75 degrees....and since the sum of all angles in a triangle is 180...add 75 and 67 which would be 142 degrees ...then minus 142 from 180 degrees to get 38 degrees for x
A pound of oranges cost x dollar => A pound of pears cost x+3 dollar
We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5
5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
So fuctions mean
if
f(x)=x+2 then if you put in 3 for x then
f(3)=3+2=5 so
if x=years after 2000
in 2020 then
2020-2000=20 so x=20
subsitute
f(20)=9204e^0.022(20)
e could be:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045
2. a computer notation exg if you have 3e11 that means 3 times 10^11
if it is 1
9240 times (2.718281828459045^(0.022 times 20))=( simplify exponent first) 9240 times (2.718281828459045^0.44)=9204 times 1.5527072185113=14291.1 or rounded to 14291
if it is 2
9204 times 10^(0.022 times 20)=9204 times 10^(0.44)=9204 times 254.491 rounded to 254
so the answer dependes on what e represents,
if e is:
1. common base of logarithms (memorised to 15 decmals) 2.718281828459045, then answer is 14291
2. a computer notation exg if you have 3e11 that means 3 times 10^11 =254
