Answer:
Length of floor = 5 m and breadth of floor = 4 m
Area of floor = length x breadth
= 5 m x 4 m = 20 m.sq
Now, Side of square carpet = 3 m
Area of square carpet = side x side = 3 x 3 = 9 m.sq
Area of floor that is not carpeted = 20 m – 9 m = 11 m.sq
Answer:
[tex]11 {m}^{2} [/tex]Step-by-step explanation:
First Condition:Given ,
Length of a floor = 5 m
Width of the floor = 4 m
Therefore,
Area of the floor
= l × b
= 5m × 4m
[tex] = 20 {m}^{2} [/tex]
Second Condition:Given,
Sides of a square carpet = 3 m
Therefore,
Area of the carpet
= s × s
= 3m × 3m
[tex] = {9m}^{2} [/tex]
At last:Now,
Area of the floor that is not carpeted is
= Area of the floor - Area of the carpet
[tex] = {20m}^{2} - {9m}^{2} [/tex]
[tex] = 11 {m}^{2} (ans)[/tex]

3z + 13 = Perimeter
determine the measurement of segment XV
Answer:
Segment XV is equal to 24 mm
Step-by-step explanation:
Both triangles are clearly congruent, both having the same type of angles as well as angle LKJ and angle VKW having the same angle measure, 21 degrees. Lastly, if you were to take out segment JL and WV, the triangles would fold the same. All of this leads to segment XV being the same as segment KL which leads it to be 24 mm. (Sorry if this is confusing, just trying to explain how my brain understood the problem. If you need me to elaborate more let me know).
What is the point slope and slope intercept of this graph below
Answer:
Line is y = -3x + 3
Slope = -3
y-intercept = 3
Step-by-step explanation:
Slope is the movement up or down, and left or right. Y-intercept is the point in which the line crosses the y-axis. In slope-intercept form (y=mx+b), m represents the slope, while b represents the y-intercept.
So since the line crosses the y-axis at positive 3, that will be the y-intercept. Now if we go from that very same point, and do rise/run, we'd move downwards 3 units and to the right 1 unit, to get our slope of -3/1 (it's written as just -3 though).
So now we plug it in: y = -3x + 3
Hope this helps you :)

9514 1404 393
Answer:
D. -17%
Step-by-step explanation:
The change from March to April is (April - March) = (100 -120) = -20. As a fraction of the March bill, that is ...
-20/120 = -1/6
As a percentage, that change is ...
-1/6 × 100% ≈ -16.667% ≈ -17%
The electric bill changed by about -17% from March to April.
_____
Additional comment
Water went up 4%; groceries went up about 14%, and restaurant changed by -15%.
The percentage change is found by ...
% change = ((new amount)/(original amount) -1) × 100%
Above, we have rearranged this to ...
% change = ((new amount) -(original amount))/(original amount) × 100%

fine the horizontal tangent line
Answer:
x = 13
Step-by-step explanation:
Given: f ( x ) = 4.5 x 2 − 3 x + 2 To determine the critical points, we must first calculate the first derivative of the function.
Differentiate the given function with respect to x using the power rule of differentiation, d d x x n = n x n − 1.
f ′ (x) = d (4.5 x 2 − 3 x + 2)
______
d x
Apply sum rule: d d x (f(x)) + g (x) = d d x f (x) + d d x g (x) } f ′ ( x) = d d x (4.5 x^2) + d d x (−3 x) + d d x (x) f ′ (x) = 9 x − 3
To determine the critical points, set f ′ (x) = 0 . 9 x − 3 = 0 9 x = 3 {∴ x = 13}
Therefore, the tangent line to f(x) is horizontal at the point x = 13

Write an equation for the line in the given form.
Contains the points (5, 2) and (8, 11); slope-intercept form
Answer:
y = 3x-13
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( 11-2)/(8-5)
= 9/3
=3
Then using slope intercept form
y= mx+b
Using one of the points and the slope
2 = 3(5) +b
2 = 15 +b
2-15 = b
-13 =b
y = 3x-13
What is an equation of the line that passes through the points (-6, -2) and
(-3, 2)?
Answer:
y = (4/3)x - 2/3
Step-by-step explanation:
From (-6, -2) to (-3, 2) we see the x-component changing by 3 units and the y-component by 4 units. Thus, the slope of this new line is
m = rise / run = 4/3.
Let's focus on the point (-3, 2). Here x = -3 and y = 2. Plugging these three values into the slope-intercept form of the equation of a line, we get:
2 = (4/3)(2) + b.
Then 2 = 8/3 + b, or 6/3 = 8/3 + b. Thus, b = 6/3 - 8/3, or -2/3.
The equation of the desired line is y = (4/3)x - 2/3
Answer:y=4/3x+6

106.666666?
Answer:
£24 and £40
Step-by-step explanation:
To divide into the ratio of 3:5, we can start by dividing into 8 parts - as 3+5=8, then do 3 parts and 5 parts to achieve the ratio.
£64 / 8 = £8
3 * £8 = £24
5 * £8 = £40
I need help i have no clue what to do!

Describe how the graph of y= 2x is the same and different from the graph of y=2x+8
Answer:
They are the same because they have the same slope, 2. and they are different because they different y-intercepts, 0 and 8.
Step-by-step explanation:
Your equations y=mx+b
m is your slope, both 2 and
b is your y-intercept, 0 for your first one because it doesn't have any, and 8 for your second one.

find the 6th term of geometric sequence whose common ratio is 3/2 and whose first term is 2
Answer:
243/16
Step-by-step explanation:
we have a1 = 2
r = 3/2
n = 6
The 6th term of the geometric sequence is 243/16
The given parameters are:
[tex]a = 2[/tex] --- the first term
[tex]r = 3/2[/tex] --- the common ratio
The nth term of a geometric sequence is:
[tex]T_n = ar^{n-1[/tex]
So, the 6th term would be:
[tex]T_6 = 2 \times (3/2)^{6-1[/tex]
Subtract 1 from 6
[tex]T_6 = 2 \times (3/2)^5[/tex]
Evaluate the exponent
[tex]T_6 = 2 \times (243/32)[/tex]
Simplify
[tex]T_6 = 243/16[/tex]
Hence, the 6th term of the geometric sequence is 243/16
