Answer:
35 ft
Step-by-step explanation:
The arch is in the shape of a semicircle.
The distance around the arch is about 110 feet. This is the same as the circumference of the arch.
The height of the arch is the radius of the arch.
The circumference of a semicircle is given as:
where r = radius
Therefore:
110 = πr
=> r = 110/π
r = 35.01 ft ≅ 35 ft
The height of the arch is 35 ft
Basically just convert this into an equation:
Let’s use “x” as the result
“•” is the multiplication symbol
Double s: s•2
Subtract t from result: =x-2
So, s•2=x-2
Answer: 6
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
Using PEMDAS, first you do the parenthesis which the value would be 9. Then you divide: 9/ 3= 3. Lastly, you add 7+3+8=18.
The product will be 18.
Hope this helps! :)
