The options provided are:
A. areaB. neitherC. circumferenceSince we are calculating the amount of paint needed to cover the inside of the circle, the question is asking to find the area. Therefore, the correct answer is A. area.
The diameter of a circle is a straight line segment that passes through the center of the circle and connects two points on the circumference, effectively dividing the circle into two equal halves.
In the context of the given question, it states that the circular picture has a diameter of 4 ft. This means that the distance from one side of the circle to the other, passing through its center, measures 4 ft.

An instrument store has 20% clearance on every instrument. A guitar originally costs $120. You take it to the cashier and they charge a sales tax of 5%.
How much did you pay for the guitar?
Answers
Answer:
P = $100.80Steps:
Price after clearance:Pc = 120 - (120/100×20)
Pc = 120 - (1.2×20)
Pc = 120 - 24
Pc = 96
Price after sales tax:P = Pc + (Pc/100×5)
P = 96 + (96/100×5)
P = 96 + (0.96×5)
P = 96 + 4.8
P = $100.80
Answer:
I’m pretty sure the answer would be $100.80
Step-by-step explanation:
1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)
2. Subtract $120-$24= $96
3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8
3. Add $96+$4.80= $100.80

A) 0.91P
B) 1.09P
C) 1.15P
D) 15.09P
HELPPPPP PLEASEEEEE!!!!!
Answers
Answer:
The first question is A) P + 0.15P + 0.08P
The second question is B) 1.09P
Step-by-step explanation:
The cost of the dinner is the amount for the dinner, P plus the tax, 8% of P, which is 0.08P, plus the 15% tip, which is 0.15P
The cost of the car is P, or $15, plus the tax is 9%, or 0.09P
P + 0.09P = 1.09P
1st one is A because you wouldn't add them together first and you wouldn't subtract so that gets rid of B, C, and D.
2nd one is B, its really easy because you would just add 0.09 to the 1.00 to get 1.09

The time taken to fill the pool if it were working alone is 18 hours.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).
Given:
When 2 pipes fill a pool together, they can finish in 5 hrs,
One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs
1 / 2 of pool = 9 hrs as given
full pool = 9 × 2 = 18 hours
Therefore, The time taken to fill the pool if it were working alone is 18 hours.
