Answer:
C) 16π ft
Step-by-step explanation:
Fencing is perimeter. The perimeter of a circle is the circumference.
The circumference of a circle is pi time diameter
C= pi*d
We know the diameter is 16
C = 16*pi ft
We will need 16 pi ft of fencing
Answer:
a) 4 people ordered streak dinner
b) 3 people ordered chicken dinner
Step-by-step explanation:
Let the number of people that ordered steak dinner be x
and the number of people that ordered chicken dinner be y
From the question,
There are 7 people in your family
Hence, we can write that
x + y = 7 ...... (1)
Also from the question
Some order the chicken dinner for $13 and some order the steak dinner for $18 and the total bill was $111.
We can then write that
13y + 18x = 111 ...... (2)
From equation (1)
x + y = 7
Then,
x = 7 - y ...... (3)
Put this into equation (2)
13y + 18x = 111
13y + 18(7 - y) = 111
13y + 126 - 18y = 111
-5y = -15
5y = 15
y = 15 / 5
y = 3
Put the value of y into equation (3) to get x
x = 7 - y
Then
x = 7 - 3
x = 4
Hence, 4 people ordered streak dinner
and 3 people ordered chicken dinner
a) 4 people ordered streak dinner
b) 3 people ordered chicken dinner
Answer:
20
Step-by-step explanation:
N + (18 - 6) = 32
Simplify bracket
N + 12 = 32
Subtract 12 from both sides to eliminate 12 on the left side
N + 12 - 12 = 32 - 12
N = 20
40 - 10 = x
This is because
Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Let, the Goal = x
It would be: x * 125% = 6750
x * 1.25 = 6750 [ 125% = 1.25]
x = 6750 / 1.25
x = 5400
In short, Your Answer would be $5400
Hope this helps!
