Answer:
113
Step-by-step explanation:
note: to find the circumference of a circle using the radius, you use this equation -- 2
r. since the radius is 18, you make the equation 2
18. that gets you 36
, which, if put into the calculator, is about 113.
Look like a linear equation. let's try finding the slope:
(7-4)/(1-0)=3
(4-1)/[(0-(-1)]=3
[1-(-2)]/[-1-(-2)]=3
indeed, it is linear, with a slope of 3
when x=0, y=4, so the y intercept is 4
the equation of the line is y=3x+4
Answer:
Step-by-step explanation:
use the distance formula to find the lengths of all the sides of the triangle, if all of the sides are the same, its an equilateral. If the sides are different in this case it is a right. You can check this by using the Pythagorean theorem. the distance formula is the square root of (x2-x1)^2+(y2-y1)^2
for the coordinates make sure that you don't mix them up, if you pair the wrong coordinates up, it won't work
(x1,y1) (x2,y2)
Given, Bodhi has a collection of 175 dimes and nickel. If she has n numbers of nickel. Then,
The number of dimes coin= 175-n.
The collection is worth $13.30.
1 nickel is worth five cents. So, n nickel will worth 0.05n.
Similarly 1 dime is worth 10 cents. So, 175-n dimes will worth 0.1(175-n).
Since the total worth is $13.30. So, we can set the equation as follows:
0.1(175-n)+0.05n=13.13.
Hence, the last option is the correct choice.
