Answer:
51.3 km²
Step-by-step explanation:
The area formula is ...
A = 1/2r²θ . . . . where θ is the central angle in radians
A = 1/2(7 km)²(2π/3) = 49π/3 km² ≈ 51.3 km²
Answer:
draw a line that intersects the first line at an acute angle using a straightedge
Step-by-step explanation:
perpendicular lines are lines that cross each other (not rays)
Answer:
£10
Step-by-step explanation:
There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.
-Assuming they buy at least 15 bags, they will get a 20% discount.
-20% discount would mean they only pay 80% of the original price. 80%=.80
-let x represent number of bean bags
£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.
(50x)(.80) + 370 = 1300
Simplify:
40x + 370 =1300
Subtract 370 from both sides
40x = 930
Divide both sides by 40
X=93/4
Simplify fraction
23 1/4
=23.25
But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.
23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.
£40(23) + £370 = £1290
£1300-£1290=£10
I hope this helps!
