The answer is
the first one is x= 18.98
a^2+b^2=c^2
8 cm^2+17 cm^2= x^2
64+289=x^2
√x^2= √353
x=18.89
<span><span>the second one is x= 18.7
a^2+b^2=c^2
7 m^2+ x^2= 20 m^2
49 m+x^2=400 m
-49 -49
</span></span>√x^2=√352
<span><span>x= 18.7
Hope this helps!</span></span>
Answer: The first equation can be used to find the answer.
The solution to y^2 is 80
Answer:
33.33%
Step-by-step explanation:
Given that CP for 20dozen = 20×90
= 1800
SP = 20×120
= 2400
Gain % = (Gain / CP) ×100
Gain = SP-CP
So is the selling price
Cp is the cost price
Hence Gain = 2400-1800
Gain = 600
Gain% = 600/1800 ×100/1
= 0.333×100/1
= 33.33%
Hence his percentage gain will be 33.33%
Since the question stated that percentage gain is to be calculated, I believe the sell price should be higher than the cost price. Hence 1.20 Cedis would not work so I used 120 Cedis instead. Thanks
Answer:
6:14 and 9:21
Step-by-step explanation:
(84)5 = 420
(73)9 = 657
420 + 657 = 1077
