Answer:
<h3> 26²/₃ liters of 15% acid and 13¹/₃ liters of 33% acid</h3>
Step-by-step explanation:
Concentration Amount of Amount
of Solution Solution (L) of Acid
15% x 0.15x
33% y 0.33y
21% 40 0.21•40
x + y = 40 ⇒ x = 40 - y
0.15x + 0.33y = 0.21•40
0.15(40 - y) + 0.33y = 0.21•40
6 - 0.15y + 0.33y = 8.4
0.18y = 2.4
y = 13¹/₃
x = 40 - 13¹/₃ = 26²/₃
Answer:
The Growth of sunflower duing 3 weeks is 8.5 inches or 8 (1/2).
Step-by-step explanation:
Given:
Growth of sunflower each week .
To find :
Total growth during 3 weeks?
Solution:
According to given data:
Growth is
- 1st week=2 and 1/2 inches=5/2=2.5 inches .
- 2nd week =2 and 3/4 inches=11/4 inches.
- 3rd week=3 and 1/4 inches=13/4 inches.
Total growth is given by,
=growth of (1st week +2 week+ 3 week)
=5/2+11/4+13/4
=34/4
=17/2
=8 and 1/2 inches.
Hence the overall growth is about 17/2 or 8.5 inches in 3 weeks .
Answer:
x > 0
Step-by-step explanation:
Domain of a function is defined by the set of x-values of the graph of a function.
From the graph attached,
x-values are starting from x > 0 [Since x ≠ 0] and moves towards infinity,
Therefore, domain of the function will be,
(0, ∞) Or x > 0
