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

To get from (16,12) to (12,9) you would multiply both 16 and 12 by 3/4 to get 12 and 9.
Rearrange to make subject x 4(x-3)/a=y
Answer:
answer is x = ay + 12/4
Step-by-step explanation:
first we cross multiply on both sides which will give us this
4( x -3)=ay
we then open the brackets by multiplying 4 with x and -3 which gives
4x - 12= ay
then take 12 to the other side
4x - 12+12= ay + 12
4x = ay + 12
divide 4 on both sides
4x /4= ay + 12/ 4
therefore x = ay + 12/ 4

850 liters of walcr was shared cqually among 5 aquariums.
Ilow many liters of water does each aquarium have?
Each aquarium has 170 liters of water in it.
Step-by-step explanation:
To get this, you need to divided 850 by 5 to get the amount of water in each tank to make sure that it is all equally distributed. This way we now know that each tank needs 170 liters of water to have an equal amount of water in each tank
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.
Can some one plz help me.
#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.
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.
Solve this proportion.
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

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

Expand the logarithm fully using the properties of logs. Express the final answer in terms of log x. log2x^2
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)

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.

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.
At the end of the 4 years, how much interest in dollars and cents did the account earn?
Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.
I just don’t get what they want so
