Jacob is painting a circular picture on his wall. If the painting
has a diameter of 4 ft, how much paint will he need to cover the
inside of the circle? Is this question asking you to find the area,
circumference, or neither?
A. area
B. neither
C. circumference

Answers

The answer is Area or A

The question is asking to find the amount of paint needed to cover the inside of the circular picture with a diameter of 4 ft. To determine the amount of paint required, we need to calculate the area of the circle.

The options provided are:

A. areaB. neitherC. circumference

Since 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.

The diameter is an important measurement when calculating various properties of a circle, such as its area and circumference.

A diner has to be cleaned before it opens for breakfast at 7 am. Cindy can clean the diner by herself in 2 hours while Emilia can do it by herself in 1.5 hours. If they both start cleaning the diner at 6 am, will they have enough time to clean before breakfast service?

Answers

Answer:

Yes, they will be able to finish in time because they will finish in 1 hour.

I hope I could help <3

I'm sorry if I'm wrong.

Step-by-step explanation:

If they start cleaning the diner at 6 am, they would  have enough time to clean before breakfast service

Equation

Equation is used to show the relationship between two or more numbers and variables.

Cindy can clean the diner by herself in 2 hours while Emilia can do it by herself in 1.5 hours. Let t represent the time taken for both of them to clean. Hence:

(1/2 + 1/1.5)t = 1

t ≅ 52 minutes

If they start cleaning the diner at 6 am, they would  have enough time to clean before breakfast service

If the cost of the meal before the tip and tax are added is represented by P, which expression models the total amount that Brandon pays?
A) P + 0.15P + 0.08P
B) P(0.15P − 0.08P)
C) P −(0.15P + 0.08P)
D) P + 0.23

The price (P) of a model car kit is $15. If the sales tax on the purchase is 9%, which expression models the cost of the kit including the tax?
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

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 = $100.80

Steps:

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

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.

What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?Passage IIIA capacitor is the name for a device that stores electrical charge. Capacitance is the amount of charge that a capacitor can hold at a given voltage. In a science class, a teacher instructed her students to determine the charge on a parallel plate capacitor with a fixed capacitance. Students conducted a few different studies with this capacitor.Study 1Students constructed an electrical circuit with the capacitor, as shown in Figure 1. The capacitor was initially uncharged.Students then charged the capacitor and recorded the voltage at specific time intervals. They then used a computer program to help them graph this information, which is recorded in Figure 2.With this data, students then calculated the current at each time interval and recorded this information in Table 1. The students noted any trends and determined that voltage and current initially change rapidly before leveling out.Study 2The teacher then introduced students to an inductor and explained that, contrary to capacitors, which store energy in an electric field, inductors store energy in a magnetic field produced by the current running through the wire. As a result,inductors oppose changes in current and act opposite of capacitors, which oppose changes in voltage. She then drew a diagram on the board for students, Figure 3.The teacher then recorded the decay in voltage over time and represented this in a graph for students, as shown in Figure 4.Finally, she plotted the drop in voltage and increase in current in a chart similar to the one that the students had produced in Study 1 (see Table 2).Question 1 of 2What is the evidence from Studies 1 and 2 that capacitors and inductors worked in opposite ways?As time progressed, capacitor voltage increased while inductor voltage decreased.As time progressed, capacitor voltage decreased while inductor voltage increased.As time progressed, capacitor current increased while inductor current decreased. which wi-fi standard offers speeds of up to 100 mbps (or higher), offers a range of up to about 300 feet, and operates in the 2.4-ghz and 5.0-ghz frequencies?
