Answer:
the value of x = 56
Step-by-step explanation:
if both are similar figures, then ratio of their
sides will be constant , so
=》14 / 17 = x / 68
=》14 / 17 × 68 = x
=》14 × 4 = x
=》x = 56
hence, value of x = 56.
i hope you got it.
Answer:
y = 2/3x
Step-by-step explanation:
3x + 2y = 6
2y = 6 - 3x
y = 3 - 3x/2 or y = - 3/2x + 3
- - - - - - - - - - - - - -
Then find the negative reciprocal of the slope of the original line.
y = 2/3x
5, 7, and 11 are prime numbers.
Given:
pH = 4.2 of tomato
Required:
hydrogen-ion concentration [H+]| for tomato juice
Solution:
The formula for the pH relating hydrogen ion concentration is pH =
-log[H+] where H+ is the hydrogen ion concentration. so, substitute the value
of pH
pH = -log[H+]
4 = - log[H+]
-4 = log[H+]
10^-4 = [H+]
[H+] = 1x10^-4M
The answer to the variable r is r=-4
