Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
Answer:
B
Step-by-step explanation:
Matches all specified equations.
Circumference of circle = 11.27π ft
so,
C = 2πr
or, 11.27π = 2πr
or, 11.27π/2π = r
so, r = 5.635 ft
now,
diameter = 2r
= 2 x 5.635
= 11.27 ft
Answer:
Since this is a right triangle with one angle and hypotenuse given and opposite side unknown, we can use the definition of sine to find the unknown side.
sin 17 = x/hypotenuse = x/19
x = 19sin17 = 5.6
The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
