A rectangular building has an area of 1,110 square meters and a perimeter of 134 meters. What are the dimensions of the building?
Answers
Answer:
The dimensions of the rectangular building are 30 meters by 37 meters.
Answer:
30 by 37 meters
Step-by-step explanation:
Refer to the attached image to understand where the following formulas came from.
[tex]\text{Area,} \ A=1110 \ m^2\\\\\text{Perimeter,} \ P=134 \ m[/tex]
We have a system of equations
[tex]\Longrightarrow \left \{ {{xy=1110} \atop {2x+2y=134}} \right.\\\\\text{Taking equation 2} \rightarrow 2x+2y=134\\\\\Longrightarrow 2x=134-2y\\\\\Longrightarrow x=67-y \\\\\text{Now taking equation 1} \rightarrow xy=1110\\\\ \Longrightarrow (67-y)y=1110\\\\ \Longrightarrow 67y-y^2=1110\\\\ \Longrightarrow y^2-67y+1110=0\\\\\Longrightarrow (y-37)(x-30)=0\\\\\Longrightarrow \boxed{y=37 \ m \ or \ 30 \ m }[/tex]
When y=37:
[tex]x(37)=1110\\\\\Longrightarrow \boxed{x=30}[/tex]
When y=30:
[tex]x(30)=1110\\\\\Longrightarrow \boxed{x=37}[/tex]
So, the dimensions of the building are 30 by 37 meters.

Anna Beth has two fish tanks. They are both cubes. The side length of one of the tanks is 15 cm. The side length of the other is 45 cm. What is the ratio of the volume of the smaller tank compared to the volume of the larger tank?(1 point)
The options are
45/15
1/27
1/3
27/1
Answers
Question 1)
Volume of Tank A = Sum of volume of its two parts.
So,
Volume of Tank A = 24 + 96 = 120 cubic feet
Question 2)
Volume of Tank B and Tank A is the same. So, Volume of Tank B = 120 cubic feet
One section of Tank B = 45 cubic feet
So, volume of other section of tank B = 120 - 45 = 75 cubic feet
hope this helps sorry
The ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27. Option B is correct.
Ratio of the volume of the smaller tank compared to the volume of the larger tank = Volume of smaller tank/Volume of larger tank.
Volume of cube = a³
a = length of side of cube.
Length of the side of the smaller tank = 15cm.
Length of the side of the larger tank = 45cm.
Volume of smaller tank = (15)³ = 3375 cm³
Volume of larger tank = (45)³ = 91125 cm³
Ratio of the volume of the smaller tank compared to the volume of the larger tank = 3375/91125 = 1/27.
Therefore the ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27.

Write each expression without the absolute value symbol.
Answers
Answer:
Step-by-step explanation:
The expression without the absolute value symbol is:
|x - 8| = x - 8, if x > 8
|x - 8| = 0, if x = 8
|x - 8| = 8 - x, if x < 8
How to solveFrom the given parameters
We have,
|(x - 19) + 11|
This can be written as,
= |x - 19 + 11|
= |x - 8|
Now,
|x - 8| = x - 8, if x > 8
|x - 8| = 0, if x = 8
|x - 8| = 8 - x, if x < 8
Thus,
The expression without the absolute value symbol is:
|x - 8| = x - 8, if x > 8
|x - 8| = 0, if x = 8
|x - 8| = 8 - x, if x < 8

Solve the congruence 5x ≡ 6 (mod7).
______, m is any integer
Answers
Answer:
Step-by-step explanation:
To solve the congruence 5x ≡ 6 (mod 7), we need to find a value for x that satisfies the equation.
First, we'll find the multiplicative inverse of 5 modulo 7. The multiplicative inverse of a modulo m is a number x such that ax ≡ 1 (mod m). In this case, we need to find a number x such that 5x ≡ 1 (mod 7).
To find the multiplicative inverse, we can try different values of x and compute the result until we find one that satisfies the equation. Alternatively, we can use a more efficient method like the Extended Euclidean Algorithm.
Using the Extended Euclidean Algorithm, we find that the multiplicative inverse of 5 modulo 7 is 3, as 5 * 3 ≡ 1 (mod 7).
Now, we can multiply both sides of the congruence by the multiplicative inverse (3) to isolate x:
5x ≡ 6 (mod 7)
3 * 5x ≡ 3 * 6 (mod 7)
15x ≡ 18 (mod 7)
Reducing the coefficients:
1 * x ≡ 4 (mod 7)
Since x ≡ 4 (mod 7), the solution to the congruence 5x ≡ 6 (mod 7) is x ≡ 4 (mod 7). This means that x can be written as x = 4 + 7k, where k is any integer.

Answers
Answer:
Mario
Step-by-step explanation:
Sheila has a 5 dollar allowance and saved for 3 weeks. 3 x 5 = 15 dollars saved total. She spends 9 of the 15. 15 - 9 = 6, so Sheila donated 6 dollars.
Mario has a 4 dollar allowance and saves for 4 week. 4 x 4 is 16 dollars saved. He then spends 8 of them, 16 - 8 = 8 dollars donated.
Gina has a 6 dollar allowance and saves for 4 weeks. 6 x 4 is 24. She then spends 17 dollars. 24 - 17 is 7 dollars donated.
Sheila donates 6 dollars. Mario donates 8 dollars. Gina donates 7 dollars.
Out of the three, Mario has donated the most.

A theater company has raised $810.75 by selling 15 floor seat tickets. Each ticket costs the same.
Part A: Write an equation with a variable that can be solved to correctly find the price of each ticket. Explain how you created this equation. (5 points)
Part B: Solve your equation in Part A to find the price of each floor seat ticket. How do you know your solution is correct? (5 points)
Answers
Let's assume the price of each floor seat ticket is represented by the variable 'x'.
Since the theater company has raised $810.75 by selling 15 floor seat tickets, we can create an equation using the concept of total revenue. The total revenue is calculated by multiplying the price of each ticket by the number of tickets sold.
Therefore, the equation can be written as:
15x = 810.75
In this equation, '15x' represents the total revenue from selling 15 tickets at the price of 'x' per ticket, and '810.75' represents the total amount of money raised.
Part B:
To solve the equation 15x = 810.75, we need to isolate the variable 'x' on one side of the equation.
Dividing both sides of the equation by 15, we have:
x = 810.75 / 15
Evaluating the division, we find:
x ≈ 54.05
Therefore, the price of each floor seat ticket is approximately $54.05.
To confirm the solution, we can substitute the value of 'x' back into the original equation:
15 * 54.05 ≈ 810.75
This equation holds true, as the left side is approximately equal to the right side. Hence, we can conclude that the solution is correct.
I hope this helps! :)
Part A: 15x= $810.75. Part B: x= $54.05
The total money earned from 15 tickets is $810.75.
Assume, the money earned from selling 1 ticket is $x.
Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75
Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.
Using the equation above,
15x= $810.75.
Dividing both sides by 15,
We get,
x= $54.05
Hence, $54.05 is the price of each ticket.

Rewrite the expression c + 0.25c as a single term with a fractional coefficient.
please help (No spam) (No stu-pid answers please)
Answers
Answer:
5c/4
Step-by-step explanation:
c = c × 1
0.25c = 0.25c × 1
c + 0.25c
Take " c " common.
= c × (1 + 0.25)
= c × 1.25
Convert 1.25 into a simpler fraction
1.25
= 125/100
= 5/4
c × 1.25
= c × 5/4
= (c × 5)/4
= 5c/4
The fractional coefficient is (5c/4)
What is a coefficient?A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term
Given:
[tex]\sf c+0.25c[/tex]
[tex]\sf =(1+0.25)c[/tex]
[tex]\sf =(1.25)(c)[/tex]
[tex]\sf =1.25c[/tex]
[tex]\sf =\dfrac{125}{100}[/tex]
[tex]\sf =\dfrac{5}{4}[/tex]

You deposit $100 in a savings account. The account earns 5% simple interest per year.
A.)What is the interest earned after 8 years?
B.)What is the balance after 8 years?
Answers
A) $40
B) $140
The deposited amount in the bank is $100
The simple interest per year on the account is 5%
Every year the account holder will earn 5% of the deposit
In this case, the account holder will earn 5% of 100$ every year
So in the first year interest earned would be= 100× 5/100
= $5
Interest earned in first year= $5
Since the deposit amount is constant and interest is 5%
Interest earned in 8 years= 5×8
= $40
Interest earned after 8 years = $40
Balance after 8 years would be= Initial balance + Interest earned
= 100+ 40
=140
The balance in the account after 8 years is $140

Amal usually brings lunch to the school in the lunch box shown below. The length, breadth, and height of the box are in the ratio of 2:3:4 and the sum of the cubes of length, breadth, and height of the box equals 33957 cm³.
Find the length of the longest edge of the box.
Find the sum of the length and breadth of the box.
Answers
Answer: length of longest side = 15092 cm
sum of length and breadth = 18856 cm
Step-by-step explanation:
1st question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
longest side is the height because it has the biggest number in the ratio
∴ longest side = 4 × 3773 = 15092 cm
2nd question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
→ length = 2 × 3773 = 7546 cm
→ breadth = 3 × 3773 = 11319 cm
∴ length + breadth = 7546 + 11319 = 18865 cm
Hope this helps!
The Length of longest edge of the box = 28 cm
The Sum of length and breadth of the box = 35 cm
Steps to calculate the length, breadth and height
Given, ratio(length : breadth : height) = (2:3: 4)
Let length = 2x, breadth = 3x and, height = 4x
Given, the sum of the cubes of length, breadth, and height of the box equals 33957 cm, therefore
[tex](2x)^3[/tex] + [tex](3x)^3[/tex] + [tex](4x)^3[/tex] = 33957
8[tex]x^{3}[/tex] + 27[tex]x^{3}[/tex] + 64[tex]x^{3}[/tex] = 33957
99[tex]x^{3}[/tex] = 33957
[tex]x^{3}[/tex] = 343
[tex]x^3[/tex] = [tex]7^3[/tex]
x = 7.
Therefore, length = 2x = 2*7 = 14 cm, breadth = 3x = 3*7 = 21 cm, height = 4x = 4*7 = 28 cm. Hence, Length of longest side(height) = 28 cm, Sum of length and breadth = 35 cm
