Lisa's living room has new carpet of 8 meters wide and 10.5 meters long. They want to put carpet in the basement that is twice as long as the living room and a fourth wider. They also wanted to put tile in the bathroom that has an area of 10 square feet. The bedroom is currently being completed with carpet. If the bedroom is 6 meters shorter in length than the living room, and is 34 the width of the living room, what is the bedroom's area in meters squared?
The bedroom's area in meters squared is 55.1693 m².
Solving for the bedroom's area in meters squared:finding the area of the basement:
The length of the basement is 2 * 10.5 m = 21 m
The width of the basement is 8 m / 4 = 2 m
The area of the basement is 21 m * 2 m = 42 m²
Next, let's find the equivalent area of the 10 square feet tile in meters:
1 square foot = 0.092903 m²
10 square feet = 10 * 0.092903 m^2 = 0.92903 m²

how many to fill these here buckets
Answer:
Each bucket will be [tex]\dfrac{1}{2}[/tex] full
Step-by-step explanation:
First add up all the different fractions to find out how many buckets of water are in all 3 buckets combined.
Adding up the fractions we get the expression:
[tex]\dfrac{5}{12} + \dfrac{3}{4} + \dfrac{1}{3}[/tex]
To add these fractions first find the LCM(least common multiple of the denominators, 12, 4 and 3
This is the smallest number divisible by all 3 numbers without a remainder
There are several strategies for finding the LCM but here we can see that 12 is evenly divisible by12, 4 and 3
We convert each of the fractions to have the same denominator as the LCM of 12 and adjust the numerator accordingly
Multiply each of the fractions by the LCM
12 x 5/12 = 5
12 x 3/4 = 9
12 x 1/3 = 4
These will become the numerators in the addition with the common denominator of 12
[tex]\dfrac{5}{12} + \dfrac{3}{4} + \dfrac{1}{3}\\\\= \dfrac{5 + 9 + 4}{12}\\\\= \dfrac{18}{12}\\\\[/tex]
This is how many buckets it will take to hold the water from all three buckets
Divide numerator and denominator by 6 to reduce to lowest fraction
[tex]\dfrac{18 \div 6}{12\div6} = \dfrac{3}{2}[/tex]
This is 1 1/2 buckets. If this amount of water is to be evenly divided among 3 buckets then the amount of water in each bucket
[tex]\dfrac{3}{2} \div 3\\\\= \dfrac{3}{2} \times \dfrac{1}{3}\\\\= \dfrac{1}{2}[/tex]
So each bucket will be half full
a small business owner is applying for a small business loan and has been approved for a $50,000 loan with a 6.15% annual interest. the first loan is a simple interest rate, the second loan compounds interest quarterly, and the third loan compounds interest continuously. the small business owner plans to pay off the loan in three years and 7 months. Determine the total value of the loan with the quarterly compounded interest.
Answer: The total value of the loan with quarterly compounded interest is $60,109.34.
Step-by-step explanation:
To calculate the total value of the loan with quarterly compounded interest, we can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A = final amount (loan + interest)
P = principal (the original amount of the loan)
r = annual interest rate as a decimal
n = number of times the interest is compounded in a year
t = time in years
For the loan with quarterly compounded interest, the number of times the interest is compounded in a year is 4 (since interest is compounded quarterly), and the time is 3 years and 7 months, which we can convert to years as 3.5833.
Substituting the values into the formula, we get:
A = $50,000 * (1 + 0.0615/4)^(4 * 3.5833)
A = $50,000 * (1.015375)^(15.7532)
A = $50,000 * 1.22186888
A = $60,109.34
Therefore, To calculate the total value of the loan with quarterly compounded interest, we can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A = final amount (loan + interest)
P = principal (the original amount of the loan)
r = annual interest rate as a decimal
n = number of times the interest is compounded in a year
t = time in years
For the loan with quarterly compounded interest, the number of times the interest is compounded in a year is 4 (since interest is compounded quarterly), and the time is 3 years and 7 months, which we can convert to years as 3.5833.
Substituting the values into the formula, we get:
A = $50,000 * (1 + 0.0615/4)^(4 * 3.5833)
A = $50,000 * (1.015375)^(15.7532)
A = $50,000 * 1.22186888
A = $60,109.34
Therefore, the total value of the loan with the quarterly compounded interest would be $60,109.34.

Answer:
SA = 439.8 in²
Step-by-step explanation:
the surface area (SA) is the total area of the 6 triangular faces and the base
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 10 and h = 6 , then
A = [tex]\frac{1}{2}[/tex] × 10 × 6 = 5 × 6 = 30 in²
so area of 6 triangles = 6 × 30 = 180 in²
Then
SA = 180 + 259.8 = 439.8 in²

The graph of the equation can be seen on the image at the end, and when she uses 17 cups of flour, she will use 76.5 cups of honey.
How to find the relation between flour and honey?We assume that the relation is linear.
Remember that a general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the linear equation passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we have the two pairs:
(27, 6)
(45, 10)
First, you can graph these two points and connect them with a line, that will be the graph of our equation.
The slope is:
a = (10 - 6)/(45 - 27)
a = 4/18
a = 2/9
y = (2/9)*x + b
To find the value of b we can replace the values of the point (27, 6)
6 = (2/9)*27 + b
6 = 2*3 + b
6 = 6 + b
0 = b
So the equation is just:
y = (2/9)*x
And for 17 cups of flour, she will use:
17 = (2/9)*x
(9/2)*17 = x
76.5 = x

How to Write the Equation of a Linear Graph?The slope-intercept form of the equation of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept.
here, we have,
To find the equation of a line that passes through two points (x1, y1) and (x2, y2), we can use the following steps:
Find the slope (m) using the formula
m = (y2 - y1) / (x2 - x1).
Plug in the slope and one of the points into the equation
y = mx + b to find b.
So, for the line that passes through the points (0, -3) and (5, -1),
the slope is (-1 - (-3)) / (5 - 0)
= 2/5,
and the y-intercept can be found by plugging in the slope and the point (0, -3) into the equation y = mx + b:
-3 = (2/5) * 0 + b
-3 = b
Therefore, the equation of the line that passes through (0, -3) and (5, -1) is: y = (2/5)x - 3

The one number is 8 less than 2 times another number. Their sums are 10
Answer:
The "one number" is equal to 4 and "another number" is equal to 6.
Step-by-step explanation:
1. We can write an equation for "one number": X = 2n - 8 (X is one number and another number is N)
2. Since their sums are 10 we can write it was X + N
3. Plug in the value of X to get: 2n - 8 + N = 10
4. Put 8 to the other side to get + 8 --> 2n + N = 10 + 8
5. Now you form the equation 3n = 18
6. N = 18 / 3 which is 6
7. To get X you do 10 - 6 which is equal to 4
8. To make sure the answer is correct plug in the values into the equation: 4 = 2(6) - 8 which simplifies to 4 = 12 - 8
Therefore, one number is equal to 4 and another number is equal to 6

a 1.1 kg weight starts at a height of 1.22 m. How fast will the pendulum swing at the bottom of its swing ?
The pendulum will swing at the velocity of 3.06 m/s at the bottom of the swing.
What is velocity?Velocity is the rate of change of position of an object, usually measured in meters per second (m/s). It is a vector quantity, which means it has both magnitude and direction. Velocity is an essential notion in physics since it is used to describe motion and is one of the fundamental principles of classical mechanics. It is connected to other notions such as acceleration, momentum, and force. Velocity is a measure of how rapidly an item moves in a specific direction, and it is computed by dividing the distance travelled by the time it takes for the object to traverse that distance.
The speed of the pendulum at the bottom of its swing can be calculated using the formula:
v = √(2gh)
where v = velocity, g = gravitational acceleration (9.8m/s2), h = height (1.22m)
Therefore, the speed of the pendulum at the bottom of its swing is:
v = √(2*9.8*1.22)
v = 3.06 m/s

Here,
Given :
=> f(−4) = −2
=> ƒ'(−4) = 6
=> f(-5) = −4
=> f'(-5) = 1
To find :
=> g(x) = ƒ(2x + 3)
=> g(4) = f(2(-4) + 3)
=> g(4) = f(-5)
=> f(-5) = -4
=> f'(-5) = 1
Therefore , the solution of the given problem of function comes out to be g(x) = ƒ(2x + 3) = f'(-5) = 1.
