Answer:
y = -4x + 9
O.R. y = 9- 4x
(both answers are equivalent, the same)
Step-by-step explanation:
1. finding gradient of perpendicular line to the equation given.
2. use the point provided in the wuestion and substitute it into the linear form of your slope-intercept form, which in my country is called the linear form, meaning straight line graph.
3. get answers by finding the y-intercept of the equation wanted.
note:
y = mx + c is how and what i use in my school as the linear form, altho every school is different and I understand that, so do check again with your teacher if it is how you do such type of questions.
Answer:
a=95.0 in^2
Step-by-step explanation:
The area of a circle is:
a=r^2
First, we must find the radius
r=d/2
r=11/2
r=5.5
Substitute 5.5 in for r in the formula
a=5.5^2
a=30.25
Substitute 3.14 in for pi
a=3.14*30.25
a=94.985
Rounded to the nearest tenth:
a=95.0 in^2
Hope this helps! :)
Answer:
$20
Step-by-step explanation:
There are a few ways to do this. We know 20% is 1/5 and 1/5 is 5 dollars. since that's the percent off, we would subtract it from 25.
For general percents off, they might not be so easy. It is important to know the method. We must multiply by the decimal of the percent, so
Now, since it is this amount off, we subtract 5 from 25.
$20 is the final price of the hat!
