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

9/n=7/5
Answer:
n = 6 3/7 or 45/7
Step-by-step explanation:
cross-multiply
7n = 45
n = 45/7 or 6 3/7
Answer:
45/7Step-by-step explanation:
9 x 5 = n x 7
45 =n x 7
Switch sides n x 7=45
Divide both sides by 7: n x 7/7 = 45/7
n = 45/7
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 y-intercept and the slope of the line.
5x+4y=-3
Write your answers in simplest form.
y-intercept:
Slope:
No choices solve on own
Answer:
y - intercept: 3/4
slope: -5/4
Step-by-step explanation:
put into slope-intercept form first, y = -5/4x + 3/4
then you can see that the slope and y - intercept are -5/4 and 3/4
Answer:
The answer for the y-intercept is (0, -3/4). The answer for the slope is -5/4.
Step-by-step explanation:
You know this because you must pull the 4 out of the equation, along with the y, so it is -4y=5x+3. You would put both of these numbers over 4: (5 and 3). A positive number which is 5, divided by a negative gives you negative so you can just say -5/4. Same with +3/-4. You can change it to -3/4, because positive over negative equals negative answer.

Move words to the blanks and equations to the boxes to prove that vertical angles 21 and 23 are congruent.
Because linear pairs of angles are
and
Because angles that are

it can be concluded that 21 23.
congruent
m21 +m22 = 180°
supplementary
m22 + m23 = 180°
m2l + m23 = 180°
Answer:
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
Step-by-step explanation:
The correct question is attached.
Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.
If angles are supplementary to the same angle, then they are congruent.
∠1 and ∠3 are vertical angles
∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:
m∠1 + m∠2 = 180° (linear pair angles are supplementary)
m∠2 + m∠3 = 180° (linear pair angles are supplementary)
Hence using transitive property of equality:
m∠1 + m∠2 = m∠2 + m∠3
Using subtraction property of equality by subtracting m∠2 from both sides gives:
m∠1 = m∠3
∠1 ≅ ∠3 (vertical angles are congruent)
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

a school hall measures 10m long,7m wide and 4m high.All it's insideswalls and ceiling are painted ,
calculate the total surface area
Answer:
304 m²
Step-by-step explanation:
l = 10 m
b = 7 m
h = 4 m
TSA = 2 (lb + bh + hl)
= 2 (10 * 7 + 7 * 4 + 4 * 10)
= 2 (70 + 42 + 40)
= 2 * 152
= 304 m²

#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 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)

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)
