Answer:
1) [tex]\frac{1}{2^7}[/tex] ; 2) [tex]11^7[/tex]
Step-by-step explanation:
1) Using the Power of a Fraction Rule [tex](\frac{a}{b} )^x = (\frac{a^x}{b^x} )[/tex],
[tex](\frac{1}{2} )^7 = (\frac{1^7}{2^7} )[/tex], which can just be simplified to [tex]\frac{1}{2^7}[/tex].
2) Using the Negative Exponent Rule, [tex]a^{-x} = \frac{1}{a^{x}}[/tex],
[tex](\frac{1}{11} )^{-7} = \frac{1}{\frac{1}{11^7}}[/tex], which can be simplified to [tex]11^7[/tex].

What is the cost of paving the path with bricks at rate of Rs.100 per m². When area of land is 63 m s
Answer:
Rs. 6300
Step-by-step explanation:
Given that:
Land area = 63m²
Rate of paving brick = RS. 100 per m²
Hence, to pave bring on a 63m² land area ;
Total cost of paving brick will be :
Cost per m² * land area
Rs. 100 * 63
= Rs. 6300

Answer:
arc AB = 90 degrees
x = 9
arc AD = 108 degrees
arc DC = 139 degrees
arc BC = 13 degrees
arc ADC = 247 degrees
Step-by-step explanation:
12x+(17x-14)+(2x+5)+90 = 360
31x+81 = 360
31x = 279
x = 9
arc AD = 12(9) = 108 degrees
arc DC = 17(9)-14 = 139 degrees
arc BC = 2(9)+5 = 23 degrees
arc ADC = 108+139 = 247 degrees

HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?
Answer:
After 3.5 hours and the charge is $82.50.
Step-by-step explanation:
Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).
13x + 37 = 17x +23
x = 3.5
Then plug the hours into either side to get the equal price.
13(3.5) + 37 = $82.50
OR
17(3.5) + 23 = $82.50

Answer:
㏒(2x²) = ㏒(2) + 2㏒(x)
Step-by-step explanation:
As given, ㏒(2x²)
As we know that ㏒(MN) = ㏒(M) + ㏒(N)
⇒㏒(2x²) = ㏒(2) + ㏒(x²)
As we know that ㏒(xⁿ) = n㏒(x)
⇒㏒(2x²) = ㏒(2) + 2㏒(x)
∴ we get
㏒(2x²) = ㏒(2) + 2㏒(x)

Kyle found that
31/97 = 0.3196. Without doing any computation, explain how we know
that Kyle is wrong.
I need the answer really quickly!!!
Answer:
The answer actually rounds to 0.3196, but the computation is so long, we just count it as 0.3196. The real answer would be 0.31958762886.

#13 and 14
Answer:
For number 13 you should get 14 is the width just divide what you got from multiplying the length and the other side. 2 and 95 could be possible answers of number 14.
Answer:
13. Width is 14 inches.
14. 5 and 38
Step-by-step explanation:
Volume (rectangular prism) = length*width*height
1428=17*w*6
w=1428/102
w=14 inches
Base area=length*width
∴Volume (rectangular prism) = Base area*height
190=Base area*height
Pick two numbers that multiply to give 190: 5 and 38.

Find the slope and the y-intercept of the line y=4x+6
Answer:
Slope: 4
Y-intercept: 6
Step-by-step explanation:
The equation is given to you in slope intercept form which is y=mx+b.
In this form m is the slope and b is the Y-intercept. Therefore all you have to do is take the value for m from the equation and put that down for the slope and the value for b as the y-intercept.

find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
2. rectangle with length (x+3) and width 7
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle?
Answer:
1= Perimeter =9.6
Area = 5.76m^2
Answer:
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
answer:
length [l]=2.4m
area of square=l²=2.4²=5.76m²
perimeter of square=4l=4×2.4=9.6m
2. rectangle with length (x+3) and width 7
answer:
length [l]=x+3
Breadth [b]=7
perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20
area of rectangle=l×b=(x+3)×7=7x+21
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.
answer:
the term for the perimeter of a circle=2πr (when radius is given ) and πd (when diameter Is given)
