A button with a circumference of 7.38 cm will need a buttonhole with the size of 2.35 cm.
Since the circumference is equivalent to 7.38 cm, the formula can be displayed as follows:
7.38 cm = 2<span>πr
r = 7.38cm/2</span><span>π
r= 1.1751592 cm
diameter = 2r
= 2.3503184 cm or approximately 2.35 cm</span>
Answer:
<em>X=</em><em>-</em><em>1</em><em>8</em><em>/</em><em>7</em>
Step-by-step explanation:
-6x+18+2x=-18x-18
-4x+18= -18x-18
-4x+18x=-18-18
14x=-36
x=-36/14
x=-18/7
First, you have to combine the 6x and the 10x you do this by subtracting 6x from each side. doing that you get....
-11=4x-51
then, you have to combine the -11 and the -51 you do this by adding 51 to each side. doing that you get....
40=4x
lastly, you need to divide each side by 4 to isolate the variable x. you get...
x=10
Answer:
The base is 11 cm.
Step-by-step explanation:
The formula for the area of a triangle is . If we plug in what we know to this equation, we are left with , which we now need to simplify.
First, we combine like terms.
Then, we can eliminate the and on the right side of the equation, since they cancel each other out.
Finally, we take the square root of both sides of the equation and find our answer:
