12 percent of 17.5 is equal t0 2.1.
Here we have to calculate,
12% of 17.5
We know that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
So in order to find percentage,
Divide 12 by 100,
Therefore,
⇒ 12% = 12/100
= 0.12
Now multiply 0.12 wit 17.5 we get,
⇒ 0.12 x 17.5
⇒ 2.1
Hence,
The required value ⇒ 2.1.

Answer:
3.6 hours.
Step-by-step explanation:
We work in terms of rates per hour:
1/9 + 1/6 = 1/x where x is the time for 2 pipes working together.
Multiply through by the LCD of 6, 9 and x ( which is 18x) :-
2x + 3x = 18
5x = 18
x = 3.6 hours.
y = x − 3
y = −x + 3
y = −x − 3
y = x + 3
Answer:
y =x+3
Step-by-step explanation:
We need to find the slope
Find 2 points
(-3,0) and (0,3)
Slope = (y2-y1)/(x2-x1)
= (3-0)/ (0--3)
= (3-0)/ (0+3)
=3/3
=1
We know the y intercept ( where it crosses the y axis) is at 3
We can write the equation in the form y= mx+b
y = 1x+3
y =x+3
3. If m=1/2 and b=2, what is the equation in slope-intercept form?
Hint the form of the equation in slope-intercept form is y=mx+b
