Answer:
603.2 meters
Step-by-step explanation:
circle - the outside of the walk in this case. This circle has a
diameter of 22 + 8 m, therefore a radius of 15m. The inner circle
has a diameter of 22m - as given - a radius of 11m.
You subtract the area of the inner circle from that of the larger circle.
Answer:
=4.1d+5.4h−18
Let's simplify step-by-step.
8h−0.9d−18+5d−2.6h
=8h+−0.9d+−18+5d+−2.6h
Combine Like Terms:
=8h+−0.9d+−18+5d+−2.6h
=(−0.9d+5d)+(8h+−2.6h)+(−18)
=4.1d+5.4h+−18
Answer:
4m
Step-by-step explanation:
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.
