Answers

The exact surface area of the given "right cylinder" is: " 1,944 π cm² " .
_______________________________________________________
Explanation:
______________________________________________________
The formula for the "surface area, S.A." of a right cone is:
______________________________________________________
→ S. A. = π r [ r + √(h² + r²) ]
______________________________________________________
in which: "S. A." is the "surface area" (in units of "cm² " ; in our case) ;
→ for which we shall solve;
π = π ; (Note, we are asked to solve for the EXACT surface area of the given "right cone" ; so we shall solve in terms of "π" ; & we note that the answer choices provided are all "in terms of π" ;
" r = "radius" of the [circular base] = diameter / 2 ;
= 54 cm / 2 = 27 cm ;
" h = perpendicular height = 36 cm " ;
____________________________________________________
→ Plug in our known values into the formula/equation ;
for the "surface area, S.A." of a right cone to solve:
____________________________________________________
→ S. A. = π r [ r + √(h² + r²) ] ;
→ S.A. = π * (27 cm) * [ 27 cm + √[ (36 cm)² + (27 cm)² ] ;
= π * (27 cm) * [ 27 cm + √[ (36² * cm²) + (27² cm²) ] ;
= π * (27 cm) * [ 27 cm + √[ (1296 cm²) + (729 cm²) ] ;
= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;
= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;
= π * (27 cm) * [ 27 cm + √ [ (1296 + 729) cm² ] ;
= π * (27 cm) * [ 27 cm + √ (2025 cm² ] ;
= π * (27 cm) * [ 27 cm + √ (2025 cm² ] ;
= π * (27 cm) * [ 27 cm + 45 cm ] ;
= π * (27 cm) * [ 27 cm + 45 cm ] ;
= π * (27 cm) * [ 72 cm ] ;
= π * (27 cm) * [ 72 cm ] ;
= (27 * 72) * π cm² ;
= (27 * 72) * π cm² ;
= " 1,944 π cm² " .

One year, a student council sold 856 copies of a school yearbook. Four fifths of the students at school bought a copy. How many students did not buy a yearbook?
Answers
By solving the equation 4/5 * x = 856, we find that the total number of students at the school is 1070. Calculating the remaining one fifth, we determine that 214 students did not buy a yearbook.
The student's question asks us to find out how many students did not buy a yearbook if four fifths of the students at school did buy one. To solve for this, we need to first determine the total number of students and then calculate the remaining one fifth who did not purchase the yearbook.
Let x represent the total number of students at the school. Since 856 copies of the yearbook were sold and this represents four fifths, we can set up the equation:
4/5 * x = 856
To find x, we divide both sides of the equation by 4/5, which is equivalent to multiplying by the reciprocal (5/4):
x = 856 * 5/4
x = 1070
Thus, the total number of students at the school is 1070. To find out how many did not buy the yearbook, we take the remaining one fifth:
1/5 * 1070 = 214

Juan lives 2.5 miles from the park. It took him 12 minutes to ride his bicycle to the park. What was Juan’s average speed in miles per hour?
Answers
12x = 150
x = 12.5 mph
Juan's average speed was found to be 12.5 mph, calculated by dividing the distance of 2.5 miles by the time of 0.2 hours.
Juan lives 2.5 miles from the park, and it took him 12 minutes to ride his bicycle there. To find Juan's average speed in miles per hour, we need to follow a few steps. First, we convert the time taken into hours because speed is often expressed in miles per hour (mph).
12 minutes is equal to 12 / 60 hours, which is 0.2 hours. Then, we use the formula for average speed:
Average speed = Total distance / Total time
So for Juan's trip, we get:
Average speed = 2.5 miles / 0.2 hours = 12.5 mph.
Therefore, Juan's average speed was 12.5 mph.

V = 1/3 HS^2
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Answers
Solving for S².
Multiply both sides by 3.
3V= 3 x 1/3 HS²
3V=HS²
Divide both sides by H.
3V/H=HS²/H
3V/H=S²
Switch sides
S²=3V/H
Answer: S² = 3V / H
Final answer:
To solve for S² in the equation V = 1/3 HS², multiply both sides by 3 and then divide by H, resulting in S² = 3V / H.
Explanation:
To rewrite the equation V = 1/3 HS² so that S² is by itself on one side of the equation, we need to use opposite operations.
We start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:
3V = HS²
Next, we divide both sides by H to solve for S²:
S² = 3V / H
Now, S² is by itself on one side of the equation, which is the desired outcome.
A restaurant has 26 tables in its dining room. It takes the waitstaff 10 minutes to clear and set 4 tables. At this rate, how long will it take the waitstaff to clear and set all the tables in the dining room?
Answers
The time it will take the waitstaff to clear and set all the 26 tables in the dining room is;
1 hour 5 minutes
We are told that the waitstaff takes 10 minutes to clear and set 4 tables.Thus, rate of clearing and setting 1 table = 10/4
rate of clearing and setting 1 table = 2.5 minutes per table
Now, we want to find out how long it will take her to clear and set 26 tables at the rate we got above.By use of proportions, we can find it as;
Time it takes to clear and set 26 tables = 2.5 × 26
Time it takes to clear and set 26 tables = 65 minutes
We know that 60 minutes make 1 hour, thus converting the time to hour and minute gives us;
1 hour 5 minutes

f (t) = 30 * (1.05) ^ t
For V we have:
f (t) = 30 * (0.95) ^ t
For VI we have:
f (t) = 30 * (0.85) ^ t
Answer:
option c.
Option: c is the correct answer.
c. φ, ε and δ
Step-by-step explanation:From the graph given to us we see that the graph passes through the same initial point that is the starting point is same i.e. when t=0.
Also, they attain the maximum value at t=0.
α: [tex]10(1.2)^t[/tex]
Now when t=0 we have:
Value=10
β : [tex]10(1.5)^t[/tex]
Now when t=0 we have:
Value=10
χ: [tex]20(1.2)^t[/tex]
Now when t=0 we have:
Value=10
δ: [tex]30(0.85)^t[/tex]
Now when t=0 we have:
Value=30
ε: [tex]30(0.95)^t[/tex]
Now when t=0 we have:
Value=30
φ: [tex]30(1.05)^t[/tex]
Now when t=0 we have:
Value=30
Hence, we see that δ , ε and φ are the three functions such that they have the same initial value.
Which equation represents the following word sentence? Five more than three times x is twenty. 5x + 3 = 20 3x + 5 +20 3(x + 5) = 20 3x + 5 = 20 Description
Answers
The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20. To solve this equation, subtract 5 from both sides and divide both sides by 3 to find the value of x.
Explanation:The equation that represents the word sentence 'Five more than three times x is twenty' is 3x + 5 = 20.
In this equation, '3x' represents three times x, and '5' represents five more than that. The equation states that the sum of three times x and five is equal to twenty.
To solve this equation, you can subtract 5 from both sides to isolate '3x', and then divide both sides by 3 to find the value of x.

Matt has 75 hundredths of a dollar. Kendra has 7 tenths of a dollar. Who has more money?
Answers
Answer:
matt
Step-by-step explanation:
Matt has 75 hundredths of a dollar ($0.75) while Kendra has 7 tenths of a dollar ($0.70). Matt has more money as $0.75 is greater than $0.70.
In this scenario:
Matt has 75 hundredths of a dollar, which is equal to $0.75.
Kendra has 7 tenths of a dollar, which is equal to $0.70.
To determine who has more money, compare $0.75 and $0.70. Clearly, Matt has more money since $0.75 is greater than $0.70.
Aliyah had $24 to spend on seven panicles after buying them she had $10. How much did each pencil cost

Subtract the $10 from the amount of money Aliyah had to spend because we already know that she will NOT use the $10 towards the pencils.
24 - 10 = 14
This is how much money Aliyah spent on seven pencils. Now, we must find the cost of each individual pencil.
Next, divide this by the amount of pencils Aliyah bought (7):
