Answer:
multiply a by 2 divide a and 3
Answer:
24
Step-by-step explanation:
in one hour he can serve 12, hence 12x2=24
Answer:
square
Step-by-step explanation:
You use the Pitagora's theorem to calculate the diagonals of the figure.
The diagonals are given by the distance NQ and MP.
By calculating the value of these diagonals you have:
These diagonlas are equal between them. Hence, the figure is a square
Answer:
The answer is the last line.
Step-by-step explanation:
Use the quadratic formula
a = 1
b = -a
c = a^2 - b
x = -b +/- sqrt(b^2 - 4ac)
=================
2a
x = a +/- sqrt(a^2 - 4(1)*(a^2 - b)
========================
2
x = a +/- sqrt(a^2 - 4a^ + 4b)
=====================
2
x = a +/- sqrt(4b - 3a^2)
===================
2
A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years
b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time
if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57
