Answer:
The area of the lawn that is covered by the water from the sprinkler is
square meter
Step-by-step explanation:
Given
The radius of the circle is 12 m
Area of the circle is
For one complete circle, the degree of rotation is 360 degrees.
Area of lawn covered by rotation of 100 degrees only is 100/360 = 5/18
The area of the lawn that is covered by the water from the sprinkler is
square meter
Answer: D. 8.50a + 6.75k + 1.75(a + k)
Step-by-step explanation:
Cost of adult meal = $8.50
Cost of kid meal = $6.75
Cost of drink = $1.75
Number of adults = a
Number of kids = k
Since everyone orders a meal and
a drink, the expression that can be used to express the total cost of the meal will be:
Cost for adults:
= (8.50 × a) + (1.75 × a)
= 8.50a + 1.75a
Cost for kids:
= (6.75 × k) + (1.75 × k)
= 6.75k + 1.75k.
To get the total cost, we add the cost for adults and kids together. This will be:
= 8.50a + 1.75a + 6.75k + 1.75k.
= 8.50a + 6.75k + 1.75a + 1.75k
= 8.50a + 6.75k + 1.75(a + k)
Therefore, the correct option is D.

Answer:
area = lengh x width is that enough of the formula? :D
Step-by-step explanation:
I'll give you the rest, just in case :P My brain got tired at the break before spring, here is the rest
400 = (L+30) X w
400 = 10+30 x 10 ( just b/c I can see 40 x 10 would be 400, calculus could also figure this out for us, but... that would be the minimum fencing he needs to buy and this questions isn't asking that, just make it fit on the back of his house, which we are not given, so just make up something, I used 10 b/c it was convenient )
400 = 40 x 10
2 sides are 40 , and one side is 10
so 90' of fence is needed
