Given:
Length of the rectangle = [tex]\dfrac{2}{7}[/tex] units
Width of the rectangle = [tex]\dfrac{3}{7}[/tex] units.
To find:
The perimeter of the rectangle.
Solution:
We know that,
Perimeter of a rectangle = 2( l + w )
where, l is length and w is width.
Using the above formula, the perimeter of the rectangle is
[tex]P=2(\dfrac{2}{7}+\dfrac{3}{7})[/tex]
[tex]P=2(\dfrac{5}{7})[/tex]
[tex]P=\dfrac{10}{7}[/tex]
[tex]P=1\dfrac{3}{7}[/tex]
The perimeter is [tex]1\dfrac{3}{7}[/tex] units.
Therefore, the correct option is C.

Given that log x = 3 and log y = 5, find log (x^2)(y^2)- log xy
Step-by-step explanation:
logx²y² - logxy
= log(x²y²/xy)
= logxy
= logx + logy
= (3) + (5)
= 8.
The value of logx²y² - logxy when log x = 3 and log y = 5 is 8.
What is a logarithm?The logarithm is the opposite of exponentiation as a function. The exponent to which b must be raised in order to obtain a number x is hence the logarithm of a number x to the base b.
Given:
log x = 3 and log y = 5
logx²y² - logxy
Calculate the above expression as shown below,
logx²y² - logxy = log x²y² / xy
logx²y² - logxy = log xy
logx²y² - logxy = logx + logy
logx²y² - logxy = 3 + 5
logx²y² - logxy = 8
Therefore, the value of logx²y² - logxy when log x = 3 and log y = 5 is 8.

Man travelled twofifth of his journey by train,onethird by bus, one fourth by car and thr remaining 3 km by foot . What is the length of his total journey
Answer:
180 km
Step-by-step explanation:
Let total length of journey = x
By train = 2/5x
By bus = 1/3x
By car = 1/4x
By foot = 3km
(2/5)x + (1/3)x + (1/4)x + 3 = x
L. C. M of 5, 3 and 4 = 60
(24x + 20x + 15x) / 60 = x
24x + 20x + 15x + 180= 60x
24x + 20x + 15x - 60x = - 180
-x = - 180
x = 180
Hence, total length of journey = 180km

Answer:
6,561
39,204
25,575
52.5625 - 7.5625 = 45
Step-by-step explanation:
(i)
(81)^2
Use (a + b)^2 = a^2 + 2ab + b^2
(81)^2 = (80 + 1)^2 =
= 80^2 + 2 * 80 * 1 + 1^2
= 6400 + 160 + 1
= 6561
(ii)
(198)^2
Use (a - b)^2 = a^2 - 2ab + b^2
(198)^2 = (200 - 2)^2 =
= 200^2 - 2 * 200 * 2 + 2^2
= 40,000 - 800 + 4
= 39,204
(iii)
165 * 155
Use (a + b)(a - b) = a^2 - b^2
165 * 155 = (160 + 5)(160 - 5) =
= 160^2 - 5^2
= 25,600 - 25
= 25,575
(iv)
(7.25)^2 - (2.75)^2
Use a^2 - b^2 = (a + b)(a - b)
(7.25)^2 - (2.75)^2 =
= (7.25 + 2.75)(7.25 - 2.75)
= 10(4.5)
= 45

A ball Is dropped from a height of 100'. The height of the ball can be determined using the equation h = -16t^2+ 100, Where H is the height, in feet, and T is the time in seconds. If age equals 0 Kama find all the values of T and determine whether the values are reasonable for this solution
Answer:
2.5secsStep-by-step explanation:
Given the height of the ball modeled by the equation h = -16t^2+ 100, where
h is the height
t is in seconds
We can find the time taken by the ball to reach the ground.
The ball reaches the ground when the height h = 0
Substitute h = 0 into the equation and find t;
0 = -16t^2+ 100
16t^2 = 100
t^2 = 100/16
t = √100/16
t = 10/4
t = 2.5secs
Hence the ball reaches the ground after 2.5secs

Write a function rule for the area of a rectangle with a length 2 ft less than three times it’s width. What is the area of the rectangle when it’s width is 2 ft?
9514 1404 393
Answer:
A(w) = w(3w-2)
A(2) = 8 . . . . square feet
Step-by-step explanation:
For width w, the length will be 3w-2, two feet less than 3 times the width. The area is the product of length and width, so is ...
A = WL
A(w) = w(3w-2)
__
To find the area for a width of 2, we put 2 where w is, then evaluate.
A(2) = 2(3·2 -2) = 8 . . . . square feet

What is the slope of AB in parallelogram ABCD?
The slope of the line [tex]\overline{AB}[/tex] is the rate at which the line rises at a point.
[tex]\mathrm{The \ slope \ of \ \overline{AB} \ is \ D.} \ \dfrac{5}{2}}[/tex]
Reasons:
The slope of a line is given by the ratio of the rise to the run of the line
The coordinates of point A = (-9, -4)
The coordinates of point B = (-5, 6)
The rise of the line [tex]\overline{AB}[/tex] = The difference in the y-values = (6 - (-4)) = 10
The run of the line [tex]\overline{AB}[/tex] = The difference in the x-values = (-5 - (-9)) = 4
[tex]Slope \ of \ \overline{AB}= \dfrac{Rise \ of \ line \ \overline{AB}}{Run \ of \ line \ \overline{AB}}[/tex]
Therefore
[tex]Slope \ of \ \overline{AB}= \dfrac{10}{4} = \dfrac{5}{2}[/tex]

Each person in a certain group supports only one of the two candidates R and T. Of the people in the group, 45 percent support Candidate R and the rest support Candidate T. How many people in the group are in favor of a flat tax
Missing Information:
Of the people in the group who support Candidate R, 58 percent are in favor of flat tax Of the people in the group who support Candidate T, 22 are in favor of a flat tax.Answer:
[tex]Total = 26.1\%N + 22[/tex]
Step-by-step explanation:
Given
[tex]R = 45\%[/tex] -- [tex]Percentage[/tex] [tex]of\ R[/tex] in the total population
[tex]Favor\ Flat\ Tax = 58\%[/tex] in group R
[tex]Favor\ Flat\ Tax = 22[/tex] in group T
Required
Determine the number of people that supports T
First, the proportion of those that supports flax rate in R needs to be calculated.
[tex]Proportion = 45\% * 58\%[/tex]
[tex]Proportion = 26.1\%[/tex]
So, those that favor flat tax rate in group R are:
[tex]Favor\ Flat\ Tax = 26.1\%N[/tex]
Where N represents the total population.
Total number of people that supports the flax tax rate is gotten by adding people that support flat tax rate in each group.
[tex]Total = Group\ R + Group\ T[/tex]
[tex]Total = 26.1\%N + 22[/tex]

Randeep purchased sandwiches and a gallon of milk for himself and his friends. Each sandwich cost $8. The gallon of milk cost $4. The total cost of the meal was $44. Which answer choice represents and solves correctly the equation for x, the number of sandwiches that Randeep purchased? DON'T FORGET THE NUMBER OF SANDWICHES RANDEEP MUST BUY TO REACH $44.
Answer: He bought 5 sandwiches.
Step-by-step explanation:
We know that he purchased sandwiches (let's suppose that he bought X ) and one gallon of milk.
The cost of each sandwich is $8, then the cost of the X sandwiches will be X times $8, or: X*$8.
The cost of the gallon of milk is $4.
The total cost will be:
$4 + X*$8.
And we know that the total cost was $44, then we have the equation:
$4 + X*$8 = $44
We can solve this for X
X*$8 = $44 - $4
X*$8 = $40
X = $40/$8 = 5
This means that he bought 5 sandwiches
