A designer enlarged both the length and the width of a rectangular carpet by 60 percent. The new carpet was too large so the designer was asked to reduce its length and its width by 25 percent. By what percent was the area of the final item greater than the area of the original?
Answers
Answer:
300%
Step-by-step explanation:
Let the length of the carpet be L.
Let the width of the carpet be W.
The original area of the carpet is:
A = L * W = LW
The length and width are enlarged by 60%.
The new length is:
L + (L * 60/100) = L + 0.6L = 1.6L
The new width is:
W + (W * 60/100) = W + 0.6W = 1.6W
The length and width are then reduced by 25%.
The new length is:
1.6L + (1.6L * 25/100) = 1.6L + 0.4L = 2L
The new width is:
1.6W + (1.6W * 25/100) = 1.6W + 0.4W = 2W
The new area will be:
A = 2L * 2W = 4LW
To find the percentage increase in the area, we subtract the original area from the new area and divide by the original area:
4LW - LW = 3LW
% increase is:
[tex]\frac{3LW}{LW} * 100[/tex] = 300%
The area of the final item is 300% greater than the original item.

What is the range of the functuon f(x)=(x-4)(x-2)
Answers
Answer:
The range is [-1, ∞).
Step-by-step explanation:
The points where the graph of this function cut the x axis are at x = 2 and x = 4 , it opens upwards and has a minimum value.
It has a minimum value when x = (2 + 4) / 2 = 3.
When x = 3, f(x) = (3 - 4)(3 - 2) = -1.
So the range is all real values of x >= -1, or [-1, ∞)

The formula for converting a temperature,C, in degree Celsius ('C) to a temperature degree Fahrenheit ('F). F=(9C+160)/5 Q:) What temperature is same on both scale.
Answers
Answer:
-40
At -40, the value on both scales are the same.
-40 °C = -40 ° F
Step-by-step explanation:
Given that;
F = temperature in Fahrenheit
C = temperature in Celsius
And;
F=(9C+160)/5 .........1
For temperature to be the same on both scale;
Temperature in Fahrenheit mist be equal to the temperature in Celsius
F = C
Substituting F = C into the equation 1;
C = (9C +160)/5
Multiply both sides by 5
5C = (9C+160)
Collecting the like terms.
5C -9C = 160
-4C = 160
C = -160/4
C = -40
F = C = -40
At -40, the value on both scales are the same.
That means;
-40 °C = -40 ° F

a system of linear equations is given by the tables. one of the tables is represented by the equation y=-1/3x+7. The equation that represents the other equation is y= x + the solution of the system is ( , )
Answers
Answer:
1). Other line is, y = [tex]\frac{1}{3}x+5[/tex]
2). Solution of the system is (3, 6)
Step-by-step explanation:
From the table (1),
Let the equation of the line from the given table is,
y - y' = m(x - x')
Where m = slope of the line
(x', y') is a point lying on the line.
Choose two points from the table which lie on the line.
Let the points are (0, 5) and (3, 6)
Slope = m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{5-6}{0-3}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, equation of the will be,
y - 5 = [tex]\frac{1}{3}(x-0)[/tex]
y = [tex]\frac{1}{3}x+5[/tex] -------(1)
Let the other line from the table (2) is,
y - y" = m'(x - x")
Two points taken from this table are (0, 7) and (3, 6)
m' = [tex]\frac{7-6}{0-3}[/tex]
= [tex]-\frac{1}{3}[/tex]
Equation of the line will be,
y - 7 = [tex]-\frac{1}{3}(x-0)[/tex]
y = [tex]-\frac{1}{3}x+7[/tex] -------(2)
Therefore, equation of the other line will be, y = [tex]\frac{1}{3}x+5[/tex]
By adding equations (1) and (2),
y + y = [tex]-\frac{1}{3}x+\frac{1}{3}x+5+7[/tex]
2y = 12
y = 6
From equation (1),
6 = [tex]\frac{1}{3}x+5[/tex]
[tex]\frac{1}{3}x=7-6[/tex]
x = 3
Therefore, solution of the system is (3, 6).
Answer:
The first line is 1/3x and 5. For the second line the answer is (3,6).
1. The budget above was created by Alex to help him plan how he will spend the money she earns. He usually earns
$20 each week by babysitting and running errands for his parents. If Alex is sick one weekend and can't earn the
$20. how much will he earn for that 4-week period (assume there are 4 weekends in the month)?
Answers
Answer:
Alex will be able to earn $60 for that 4-week period.
Step-by-step explanation:
It is given that
Income to Alex each week by babysitting and running errands:
$20.
To find the 4-week period earning, we need to add the value $20 for 4 times:
20 + 20 + 20 + 20 = $80
OR
In other words, 4 week period earning = 4 [tex]\times[/tex] 20 = $80
But, Alex was sick at one of the weekends, so $20 would be earned less.
Hence, during that 4-week period, total earning = $80 - $20
[tex]\Rightarrow[/tex] $60
So, Alex will be able to earn $60 for that 4-week period.

Step-by-step explanation:
Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 18% each week. The following function represents the weekly weed growth: f(x) = 86(1.18)x. Rewrite the function to show how quickly the weeds grow each day. f(x) = 86(1.02)x; grows approximately at a rate of 0.2% daily f(x) = 86(1.18)7x; grows approximately at a rate of 1.8% daily f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily f(x) = 86(1.187)x; grows approximately at a rate of 0.18% daily
Answers
Answer:
Correct option: third one
f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily
Step-by-step explanation:
We can rewrite the equation using the model:
P = Po * (1 + r/n) ^ (nt)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the relation of the rate and the time (in our case, the rate is weekly and the time will be in days, so n = 7)
With P = f(x), Po = 86, r = 0.18 and t = x, we have:
f(x) = 86 * (1 + 0.18/7) ^ (7x)
f(x) = 86 * (1.02) ^ (7x)
So the daily rate of growth is approximately 2%
Correct option: third one

B. between 2.5 and 3.0 and between 4.0 and 4.5
C. between 2.0 and 2.5 and between 3.5 and 4.0
D. between 2.5 and 3.0 and between 3.5 and 4.0
Answers
Answer:
Option B.
Step-by-step explanation:
If the value of function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersect x-axis at its zeroes.
From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5.
It means, the graph of function must intersect x-axis in interval 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.
Therefore, the correct option is B.

What is the area of the composite figure? (6π + 4) cm2 (6π + 16) cm2 (12π + 4) cm2 (12π + 16) cm2
Answers
Answer:
16 + 6pi
Step-by-step explanation:
We have a square and 3 semicircles
The area of the square is
A = s^2 and the side length is 4
A = 4^2 = 16
The radius of the semi circle is 2
The area of a semicircle is
1/2 pi r^2
1/2 pi (2)^2 = 2pi
We have 3 of them
3 *2pi = 6pi
Add the areas together
16 + 6pi
Answer:
(6π + 16) cm²
Step-by-step explanation:
The composite shape can be cut into 4 shapes.
3 equal semi-circles and 1 square.
The square has a side length of 2 + 2 = 4cm.
The radius of the semi-circle is 2 cm.
The area of the square is:
4 × 4 = 16 cm²
The area of the semi-circle is:
2²π × 1/2
= (2π) cm²
There are 3 equal semi-circles, so multiply the area by 3.
2π × 3 = (6π) cm²
Add the areas of the 4 shapes.
16 cm² + (6π) cm²
= (6π + 16) cm²
The total area of the composite shape is (6π + 16) cm².

Pat's Potato farm grew 490 ponds of potatoes. Pat delivered 3/7 of the potatoes to the vegi stand. The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store,witched packedged half of the potatoes that were delivered into 5 pound bags. How many 5 pound bags did the grocery store package?
Answers
Answer:
Step-by-step explanation:
Pat's Potato farm grew 490 pounds of potatoes. If Pat delivered 3/7 of the potatoes to the vegi stand, it means that the number of pounds of potatoes that pat delivered to the vergi store is
3/7 × 490 = 210 pounds
The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store. It means that the amount delivered to the grocery store is
2/3 × 210 = 140
If half of the delivered potatoes was packaged in bags of 5 pounds each, it means that the amount of potatoes packaged in the bags is 140/2 = 70 pounds.
The number of bags of 5 pounds that the grocery store packaged is
70/5 = 14 bags
The probability that a foot ball team will win a game is 2/11.The probability that they will lose is 3/11.What is the probability the game will be a draw
Answers
Answer:
6/11
Step-by-step explanation:
Since there are 3 possible outcomes for the game (win,lose and draw) and the total probability for the three outcomes must be equal to 1.
Then;
The probability that the game will be a draw Pd = 1 - (probability that they will lose Pl + probability that they will win Pw)
Pd = 1 - (Pl + Pw) ........1
Given;
Pl = 3/11
Pw = 2/11
Substituting the values into equation 1;
Pd = 1 - (2/11 + 3/11)
Pd = 6/11
The probability that the game will be a draw Pd = 6/11
