50% so 9/18, or 1/2 simplified
Answer:
21
Step-by-step explanation:
Hi there!
We are given the expression x(y-z), and we want to evaluate it if x=3, y=9, and z=2
As we're given the values of the variables, we can substitute those values into the expression to find out what the value of the expression is.
So substitute 3 as x, 9 as y, and 2 as z in the expression above
x(y-z)
3(9-2)
Now we must follow the order of operations; start by subtracting 2 from 9 (do the stuff inside the parentheses first)
3(7)
Now multiply 3 and 7 together
<u>21</u>
Hope this helps!
7/8π
The circles have the same central angle measures; therefore, the ratio of the intercepted arcs is the same as the ratio of the radii.
4/7 = 1/2π over x
x = 7/8π
Answer:
H
Step-by-step explanation:
In this question, I will assume that the cost refers to the selling price (original price without discount) of the hammer.
Let the cost of each hammer be c.
∴ Cost of 50 hammers= 50c
Cost of 50 hammers= amount paid +discount given
50c= 100 +25
Here, we add the discount given since the actual cost would be $25 more than the total amount the contractor paid.
Since none of the options match our equation above, let's rearrange the equation.
Subtract both sides by 25:
50c -25= 100
Thus, H is the correct option.

Answer:
1 cm
Step-by-step explanation:
Since the perimeter is 4 cm and all the sides of the square have the same length, each side must be 1 cm long.
The area of that square is 1 cm x 1 cm, which is 1 cm2.
