A) √50 = 2√25 . Her mistake was that she confused the radicand (25) & the outside factor to the radicand that is 2. The write answer is 5√2 & not the opposite
b) Find 2 numbers where their square nears the lower & the upper end of 50.
For instance 7² = 49 & 8² =64 are the nearest lower & upper numbers that encompass 50
Hence we can write the following inequality:
49<50<64 & √49<√50√64 ==> 7<√50<8
So the √50 is nearer to 7² rather than 8².
Then let's try 7.1² =50.41 Which is an acceptable approximation
700,000
Look at the ten thousands place. There is a 7, which is greater than five, so that means you have to round the number 6 up to a seven
Answer:
x > (c-b)/a
Step-by-step explanation:
ax+b>c
Subtract b from each side
ax+b-b>c-b
ax <c-b
Divide each side by a
ax/a >(c-b)/a
x > (c-b)/a
Scalene, because they all have different lengths on each side.
Answer:
10
Step-by-step explanation:
area=√3/4×a^2
100√3 = √3×a^2
a^2 = 100
a=10
side = 10
