Answer
Find out the total cost for their dinner.
To prove
As given
For dinner, Abelita chooses the Italian salad that costs $3.99 before tax.
Franco chooses the fettuccini alfredo that costs $7.17 before tax.
Total cost of the dinner before tax = $ 3.99 + $7.17
= $ 11.16
As given
If the sales tax is 5 percent .
5 % is written in the decimal form.
= 0.05
5% tax on the dinner cost = 0.05 × 11.16
= $0.558
Total cost of the dinner = Total cost of the dinner before tax + tax cost
= $11.16 + $0.558
= $ 11.718
= $11.72 (approx)
Therefore the total cost for their dinner is $ 11.72 (approx)
Answer: The significance of the number 82.75 in the equation = amount charged per acre in the park.
Step-by-step explanation:
Given: The Green Lawns Company uses the equation C=82.75a+56 to determine the amount to charge for mowing a city park, where a is the number of acres in the park and C is the cost in dollars.
In linear equation y=mx+c, = rate of change of y with respect to x.
Here Coefficient of a = rate of change of C with respect to a.
i.e. Coefficient of a =amount charged per acre in the park.
Hence, The significance of the number 82.75 in the equation = amount charged per acre in the park.
She can cut 6 pieces. Here's how.
Three yards are 108 inches, 16 can go into 108, 6.75 times.
Hello,
Let 's a the width,
b the heigth
2a+b=80==>b=80-2a
Area=A(a,b)=a*b=a*(80-2a)
=-2a²+80a
=-2(a²-2*20a+20²-20²)
=-2(a-20)² +800
Area is maxi if a=20 and area max=800
Answer: OPTION A
Step-by-step explanation:
It is important to remember the "Angle Addition Postulate" in order to solve this exercise.
You have this larger angle:
According to the "Angle Addition Postulate", if the point "C" is in the interior of , then the measure of this angle can be obtained by adding the angle 
and the angle 
.
You can observe in the figure that:
Then you get that:
Therefore, the correct answer is Option A.
