Answer: 5.4545 ounces
Step-by-step explanation:
Given the following :
Acid solution required = 75% acid solution
Let the number of ounces of 20% acid solution required = s
Then total ounces acid required can be expressed as :
=0.20s + 0.90 x 20
= 0.20s + 18
While the total ounces required is :
s + 20
Hence, (total ounces of acid / total ounces) = 75% acid solution
= (0.2 + 18) / (s + 20) = 0.75
= 0.2s + 18 = 0.75( s + 20)
0.2s + 18 = 0.75s + 15
18 - 15 = 0.75s - 0.2s
0.55s = 3
S = 3 / 0.55
= 5.4545 ounces
Answer:
$3,208
Step-by-step explanation:
If you are asking without including taxes this would be your answer. There are four weeks in a month, so you would multiply 802 by 4.
Answer:16.8 cm^3
Step-by-step explanation:
If you multiply all of the dimension you get 16.8cm^3
Answer:
Step-by-step explanation:
6x-1+3x+5x+3+4x+8+5x+5=360 degree(sum of exterior angle of a pentagon is 360 degree)
23x+15=360
23x=360-15
x=345/23
x=15
therefore the value of x is 15 degree.
