The movie theater in town has 4 rooms. Each room has 58 seats on the left side and 32 seats on the right side. Which equation could be used to show the total number of seats in the theater?
A) 52 + 32= ?
B) 4 + 32 + 58= ?
C) (58 + 32) x 4= ?
D) (58 - 32) x 4= ?
Answers
Answer:
The right option is (C) (58 + 32)×4
Step-by-step explanation:
Total number of rooms = 4
Number of seats on left = 58 seats in each room
Number of seats on right = 32 seats in each room
Total number of seats in a room = 58 + 32 seats
Total number of seats in the movie theater = Number of rooms × Number of seats in each room
Total number of seats in the movie theater = 4 × (58 + 32) = 360 seats
Hence the right option is (C) (58 + 32)×4

How many 4-letter code words can be made using the letters in the word pencil if : (a) Repetitions are permitted?
Answers
Final answer:
The total number of code words is 6 x 6 x 6 x 6, which is 1296 possible code words.
Explanation:
To determine how many 4-letter code words can be made using the letters in the word 'pencil' with repetitions permitted, we consider that each position in the 4-letter code word can be filled by any of the 6 letters from the word 'pencil'. Therefore, for each position, there are 6 choices.
Using the fundamental counting principle, the total number of possible 4-letter code words given that repetitions are allowed is calculated as follows:
First position: 6 possibilitiesSecond position: 6 possibilitiesThird position: 6 possibilitiesFourth position: 6 possibilitiesThus, the total number of code words is 6 x 6 x 6 x 6, which is 1296 possible code words.

Answers
Answer: B
Step-by-step explanation:
The solution is Option B.
The volume of the triangular prism is given by the equation V = 432 feet³
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the prism be represented as V
Now , the equation will be
Let the base area of the prism be B
Let the height of the prism be h = 2 feet
Now , the length of the prism L = 18 feet
The width of the prism W = 12 feet
So , the base area B = L x W
Substituting the values in the equation , we get
The base area of the prism B = 216 feet²
So , Volume of Prism = B x h
Substituting the values in the equation , we get
Volume of Prism V = 216 x 2 feet³
Volume of Prism V = 432 feet³
Hence , the volume of prism is 432 feet³

In a sale, normal prices are reduced by 20%. The sale price of a shirt is £26. Calculate the normal price of the shirt
Answers
The original price of the shirt before the 20% discount was £32.50.
Explanation:In your question, you've stated that a shirt was bought at a sale price of £26, after a reduction of 20%. Therefore, the 20% reduction is equivalent to the difference between the original price and the sale price. To find the original price, we need to understand that the £26 is 80% of the original price as 100% (the original price) minus the 20% reduction equals 80%. So, we can set up the equation as follows:
0.80(x) = 26
To find the value of x (the original price), we divide both sides of the equation by 0.80
x = 26 ÷ 0.80
Therefore, the original price of the shirt was £32.50.

Ms. Reynolds has a system of 10 sprinklers that water her entire lawn. The sprinklers run one at a time, and each runs for the same amount of time. The first 4 sprinklers run for a total of 50 minutes. How long does it take to water her entire lawn?
*please explain how you got the answer if possible*
Answers
you are told that 4 sprinkles run one at a time for 50 minutes total. that means that T should be 50/4 = 12.5 minutes = 12 minutes and 30 seconds
Final answer:
To water the entire lawn with 10 sprinklers, each running for the same amount of time, it will take a total of 125 minutes.
Explanation:
Ms. Reynold's system of sprinklers is designed to run sequentially, with each sprinkler getting an equal duration of run time. We know that the first 4 sprinklers run for a total of 50 minutes.
To find out how long one sprinkler runs, we divide the total time of 50 minutes by the number of sprinklers that have run, which is 4:
50 minutes ÷ 4 sprinklers = 12.5 minutes per sprinkler.Now that we know each sprinkler runs for 12.5 minutes, we can calculate the total time to run all 10 sprinklers by multiplying the time per sprinkler by the total number of sprinklers:
12.5 minutes per sprinkler × 10 sprinklers = 125 minutes.Therefore, it will take 125 minutes to water her entire lawn using all 10 sprinklers.

there are 238 juniors at a high school. the ratio of girls to boys in the junior class 3:4. how many Juniors are girls? how many are boys?
Answers
1. Add the numbers in the ratio together:

2. Divide that number by the quantity given:
238 / 7 =
34
3. Multiply each part of the ratio by the quotient:
4 x 34 = 136
3 x 34 = 102
102 + 136 = 238
4. Answer the problem using the information you just found:
The ratio of girls to boys in the junior class is 102 : 136.
The number of juniors in a class is 238 and the ratio of girls to boys is 3:4. We can use this information to calculate that there are 102 girls and 136 boys in the junior class.
Explanation:The question provides us with the information that there are 238 juniors in the school and the ratio of girls to boys in this class is 3:4. This means for every 7 students (3 girls and 4 boys), there are 3 girls and 4 boys.
First, let's find out how many 'sets' of 7 students there are in the total number of juniors. To do this, we divide 238 by 7, which equals 34 sets.
To find out the number of girls, we multiply these 34 sets by 3 (because the ratio tells us there are 3 girls in each set). This comes to 102 girls.
Similarly, to find out the number of boys, we multiply these 34 sets by 4 (because the ratio tells us there are 4 boys in each set). This gives us 136 boys.
Therefore, in the junior class, there are 102 girls and 136 boys.
