The answer is B because Chris and three of his friends is 4. Then, each person paid $9 so 4 x 3 = x.
Answer: 320°
Step-by-step explanation:
This is a circle geometry.
The arc length of the circle is given to be 8πcm and the radius is 4.5cm.
Now the length of an arc of a circle is
Arc length = πr0°/180° or 2πr0°/360°
To find the angle 0° subtend at the center we equate the arc length with the formula and solve for 0°.Now we go
πr0°/180 = 8π, convert to a simple linear equal and solve for the angle.
πr0° = 8π × 180
0°. = 8π × 180
-----------
π × r
= 8 × 180. 8 × 180
-------- or ---------
9/2. 4.5
= 8 × 180 × 2
------------
9
= 8 × 20 × 2
= 320°
or 8 × 180/4.5
= 1440/4.5
= 320°
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
Answer:
y= -2x-1
Step-by-step explanation:
Write in slope-intercept form, y=mx+by=mx+b.
-8 3/8 - 2 1/2 = 67/8 - 5/2 = 67/8 - 20/8 = 47/8 also = to 5 7/8
67 - 20 =47
answer: 5 7/8
