Answer:
7.5kilometer
Step-by-step explanation:
for 30mins semin runs 5kilometer
then for 1min: (1min×5kilometer)÷30mins,
therefore, for 45mins: (45mins×5kilometer)÷30mins=7.5kilometer
Answer:
36π mm²
Step-by-step explanation:
Please, Mark, it's π or pi, not pie.
Formula for the area of a circle: A = πr²
so, if the radius is 6 mm, the area is A =π(6 mm)² = 36π mm²
Answer:
82% and 82/100 (or 41/50)
Step-by-step explanation:
multiply 100 times .82 to get the percent
.82 is 82/100
Y = -7sin(x) + 2cos(x)
y = -7sin(3π/4) + 2cos(3π/4)
y = -7sin(9.42/4) + 2cos(9.42/4)
y = -7sin(2.355) + 2cos(2.355)
y = -7(0.03698381721) + 2(0.9993158646)
y = -0.2588867205 + 1.998631729
y = 1.739745009
