Answer:
135
Step-by-step explanation:
9/4=2.25
60 x 2.25=135
She can do 135 jump in 60 seconds
You don't multiply both of them, it's a coordinate function. There's suppose to be a comma in between
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
Rounded, it would be 4.064.
Both number have filled circle meaning that t does contain -3 and 4.
t > equal to -3
t < equal to 4
