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

Answer:
You would earn $81.25 per week.
Step by step process:
1 hour = $6.50 ( per hour means what you would get in an hour's time.)
12 1/2 = x
If more less divides. Let x be the subject. ( 12 1/2 is the same as 12.5 or 25/2)
x = 12.5 hours × $6.50 / 1 hour ( 1 hour will cancel out 12.5 hours 12.5 times.)
x= 12.5 × $6.50
x = $81.25
Answer: by the looks of it you’re dealing with exponents. so the exponent of 3 ^2 would be 3 • 3 =9. So now the equation is 10-9 = 1.
Step-by-step explanation: The next one is the same. 9•9=81 // 3 + 81= 84
