Marco's living room is 4 meters wide and 6 meters long. He wants to install white carpet that costs $8.91 per square meter. How much will it cost to buy enough carpet for the living room?
Answer:
$213.84
Step-by-step explanation:
Think of a rectangle. In the case the length is 6 meters and the width is for meters. To be able to find the area of this rectangle, you need to multiply the length by the width. 6 multiplied by 4 is 24. In the equation it tells you that 1 square meter is $8.91, so now you are trying to figure how much 24 square meters would cost. To figure this out, you will need to multiple 24 by $8.91 giving you $213.84.

Solve the rational equation:
2x 2x-5 -3 x-1 x²-3x+2 X-2
A. x= -0.47, X = -3.27 O
B. There is no solution.
C. X = -2, x = -1
D. x = 1, x = 2
The solution to the equation [tex]\frac{2x}{x - 1} - \frac{2x -5}{x^2 - 3x + 2} = \frac{-3}{x -2}[/tex] is (b) there is no solution.
How to solve the rational equation?The equation is given as:
[tex]\frac{2x}{x - 1} - \frac{2x -5}{x^2 - 3x + 2} = \frac{-3}{x -2}[/tex]
Factorize the quadratic numerator
[tex]\frac{2x}{x - 1} - \frac{2x -5}{(x - 1)(x - 2)} = \frac{-3}{x -2}[/tex]
Multiply through by (x - 1)(x - 2)
2x(x - 2) - (2x -5) = -3(x - 1)
Expand
2x² - 4x - 2x + 5 = -3x + 3
Collect like terms
2x² - 4x - 2x + 3x + 5 - 3 = 0
Evaluate the like terms
2x² - 3x + 2 = 0
Using a graphical tool, the above equation has no real solution
Hence, the solution is (b) there is no solution.

Answer:
x = 2.5
Step-by-step explanation:
- 2x + 14 + 10x = 34 , that is

A tree casts a shadow of 20 meters when the angle of elevation of the sun is 24°
Find the height of the tree to the nearest meter.
The height of the tree is 9 meters
What is angle of elevation?This is the angle the line of sight makes with the horizontal.
Analysis:
The line of sight , the shadow length and height of tree form right angled triangle.
Let the height of tree be h
so that, tan 24 = h/20
h = 20 tan 24
h = 20(0.445) = 8.9m = 9m
In conclusion, the height of the tree is 9m.

The ratio of the one leg of
the right triangle to the other
leg of the right triangle must
be 8:7. Determine the
greatest length of one leg of
the right triangle given the
other leg of the right triangle
is 10.5 feet.
Answer:
12 ft
Step-by-step explanation:
We assume right triangle ABC with the right angle being at B. We are given that the ratio of AB/CB = 8/7, and one leg is 10.5. Let's call the other leg is X. We don't know which leg is which so assume both. Then
(a) assume the X leg is the longer
8 / 7 = X / 10.5
(8 * 10.5) / 7= X
X = 12
OR (b) assume the X leg is the shorter
8/7 = 10.5 / X
(8X / 7) = 10.5
8X = 10.5 * 7
8X = 73.5
X = 9.1875
(a) is the greater so (a) wins

what is the meaning of Interest rate
Answer:
Interest rate is a proportion of a loan rewarded as interest to the borrower, usually expressed as an annual percent of the current loan.
Answer:
See below
Step-by-step explanation:
An interest rate is basically a percentage of principal charged by the lender for the use of its money, and it is paid via simple interest (usually in an annual period). That principal is the amount of money loaned.
For example, you may have seen a 1.5% annual interest rate, or something like that. This means that if your principal was $5000, let's say, you would have to pay $5000 * 0.015 = $75 in interest per year.

What is the solution to this matrix equation?
By using a system of equations, we will see that the solution is:
x = 25, y = -50, z = -15
How to solve the matrix equation?We can write this as a system of equations:
4x + 2y - z = 15
x + y - z = -10
-3x - y + z = 60
Notice that if we add the second and third equations, we get:
(x + y - z) + (-3x - y + z ) = -10 + 60
-2x = 50
x = 50/-2 = -25
So we already got the value of x. Replacing that in the second equation we et:
25 + y - z = -10
Isolating y we get:
y = -10 - 25 + z = z - 35
Now we can replace that in the first equation:
4x + 2y - z = 15
4*25 + 2*(z - 35) - z = 15
100 + z - 70 = 15
z = 15 - 100 + 70 = -15
And using:
y = z - 35 = -15 - 35 = -50
Then the soution to the matrix equation is:
x = 25, y = -50, z = -15

a body starts from rest and moves with uniform acceleration of 4m/s² until it travels a distance of 800m,find the velocity
Answer:
80 m/s
Explanation:
Given:
i) initial velocity (as starts from rest) = 0 m/s
ii) acceleration: 4 m/s²
iii) distance travelled: 800 m
Formula required:
(final velocity)² - (initial velocity)² = 2 × acceleration × distance
Now solve:
v² - 0² = 2 × 4 × 800
v² = 6400
v = √6400
v = 80 m/s
