the cost of plastering the wall of a room which is 4m high and breadth is one third of its length is Rs 640 at the rate of Rs 5/ meter square. What will be the cost of carpeting its floor at rate of rs 250/ meter square.
Answer:
Step-by-step explanation:
Please refer to the attachement. I defined the height (H), width (W), and length (L) and set:
H = 4m and W = (1/3)L. The total cost of 640 Rs/m^2 is divided by the rate cost of Rs 5/m^2 to give 128 m^2 that was plastered. The total area of the walls must be 128 m^2, so then calculate the total wall area: The walls for the length are 2*LH and for the width are 2*WH. Substituting, we have a total of 8*L + (4/3)L = 128 m^2. Solve for L to obtain L = 12m. W is 1/3L, or 4m. The room is (W,L,H) 4, 12, and 4 meters. The floor is W*L, or 48m^2. At Rs 250/m^2, the rug will cost Rs 12000. Ouch.

Step-by-step explanation:
It took Jack 2 hours to paddle 6.4 km upstream on the Black River to the giant's castle. The speed of the river is 1.8 km/h. How long will it take Jack to cross Swan Lake if the lake is 2.5 km long?
To find the time Jack takes to cross Swan Lake, his average speed is required:
The time it will take Jack to cross Swam Lake is 0.5 hours
Reason:
Time it took Jack to paddle 6.4 km upstream, t = 2 hours
Distance Jack paddled, d = 6.4 km
The given speed of the Black River, v₂ = 1.8 km/h
The width of the lake, w = 2.5 km
The time it will take Jack to cross Swan Lake
Let v₁, represents Jack's speed, we have;
[tex]v_1 - v_2 = \dfrac{d}{t}[/tex]
Therefore;
[tex]v_1 - 1.8 = \dfrac{6.4}{2} = 3.2[/tex]
v₁ = 3.2 + 1.8 = 5
Jack's speed, v₁ = 5 km/h[tex]Time \ to \ cross \ the \ lake , \ t_S = \dfrac{w}{v_1}[/tex]
[tex]t_S = \dfrac{2.5 \, km}{5 \, km/h} = 0.5 \, hr.[/tex]
The time it will take Jack to cross Swan Lake, [tex]t_S[/tex] = 0.5 hours

8.19 divided by 4.2 SHOW UR WORK DONT SAY DO CAUCULATIONS
Answer:
1.95
Step-by-step explanation:
We can use basic arithmetic to find the answer of your question through long division.
8.19/4.2 is basically 819/420, just multiplying both sides by 100 to get rid of the decimal point.
Using long division, we can subtract 420 from 819 to add 1 to the quotient and work with 399. Currently, our quotient is 1 with a remainder of 399
Since we can not get a positive number from 420-399, we must add a 0 to 3990 along with adding a decimal point to behind the 1. 420 can fit into 3990 9 times, so we add 9 after the decimal's point, and subtract 420*9=3780 from 3990, which is 210. Right now, our quotient is 1.9 with a remainder of 210.
Because we can not subtract 420 from 210 to get a positive number, we must add another 0 to 210 to get 2100. 420 can fit into 2100 5 times, so we remove 2100 from 2100, leaving no remainder. We also add 5 to the quotient, behind the 9. Now, our quotient is 1.95, the answer.

The value of x is a
(Simplify your answer. Use a comma to separate answers as needed.)
Answer: x = 22
Step-by-step explanation:
Compare the 2 triangles
[tex]\frac{2x-8}{24} = \frac{45}{x+8}[/tex]
Cross multiply
(2x-8) (x+8) = 45 x 24
2x^2 + 16x - 8x - 64 = 1080
2x^2 + 8x - 64 - 1080 = 0
2x^2 + 8x - 1144 = 0 ---> divide by 2
x^2 + 4x - 572 = 0
(sum and product)
x^2 - 22x + 26x - 572 = 0
x(x - 22) + 26(x - 22) = 0
(x + 26) (x - 22) = 0
x + 26 = 0
x = -26
x - 22 = 0
x = 22

Form a polynomial whose real zeros and degree are given.
Zeros: -1, 0, 4;
degree: 3
Answer:
f(x)=x(x-3) x (x+4) x (x-9
Step-by-step explanation:
your function in factored form
The polynomial whose real zeros and degree are given is f(x) = x³ - 3x² - 4x
How to form the polynomial?The given parameters are:
Zeros: -1, 0 and 4Degree = 3Rewrite the zeros as:
x = -1, x = 0 and x = 4
Set the zeros to 0
x + 1 = 0, x = 0 and x - 4 = 0
Multiply the zeros
(x + 1) * x * (x - 4) = 0 * 0 * 0
Multiply the factors
(x² + x) * (x - 4) = 0
Multiply the factors
x³ - 4x² + x² - 4x = 0
Evaluate the like terms
x³ - 3x² - 4x = 0
Express as a polynomial function
f(x) = x³ - 3x² - 4x
Hence, the polynomial whose real zeros and degree are given is f(x) = x³ - 3x² - 4x

The city Music Hall charges $24.00 per adult and $14.00 per senior citizen. One day 492 people attended a concert. The total for tickets purchased
was $7878.00. How many senior citizens attended the concert?
O 393 senior citizens
O 99 senior citizens
O200 senior citizens
O 292 senior citizens
Answer:
Adults (x) = 99 and
Seniors (y) = 393
393 seniors
Step-by-step explanation:
Adults= x
Seniors = y
1) x+ y = 492
2) 24x + 14y = 7,878
1) x = 492 - y
2) 24 (492 - y) + 14 y = 7,878 (substitution)
11808 - 24y + 14y = 7,878
11,808 - 10y = 7,878
11,808 - 7,878 = 10y
3,930/10 = y
y = 393
1) x + 393 = 492 (substitution)
x = 492 - 393
x = 99

Find the least square number divisible by 5, 10, 15. (a) 100 (b) 625 (c) 900 (d) 225
Answer:-
900

[tex]\\ \sf\longmapsto \dfrac{900}{10}=90[/tex]
[tex]\\ \sf\longmapsto \dfrac{900}{15}=6[/tex]
Answer:
a) 100
→ [tex]\frac{100}{5}[/tex] = 20
→ [tex]\frac{100}{10}[/tex] = 10

Step-by-step explanation:
Scores on the ACT exam have a N(μ = 18,σ = 6) distribution, while scores on the SAT
exam have a N(μ = 500,σ = 100) distribution. Suppose Xiaoyu got a 27 on the ACT
exam, while Emily got a 720 on the SAT exam. Who has the higher relative score? Why?
Answer:
Emily has a higher relative score since her z-score is higher. This would mean she scored further above the mean than Xiaoyu.
Step-by-step explanation:
Find the z-scores by subtracting the score they got by the mean and then dividing by the standard deivation of their respective exams.
Xiaoyu:
z = [tex]\frac{27 - 18}{6}[/tex] = 1.5
Emily:
z = [tex]\frac{720 - 500}{100}[/tex] = 2.2
______
Emily has a higher relative score since her z-score is higher. This would mean she scored further above the mean than Xiaoyu.
Anyone know these answers for math??
Answer:
7) No
8) Yes
Step-by-step explanation:
7) 15 + 2y = -12 - 4y when y = -0.5
15 + (2*-0.5) = -12 - (4*-0.5)
15 + -1 = -12 - (-2)
15 - 1 = -12 + 2
14 = -10
The numbers are different on both sides so -0.5 is not a solution
8) 5 - 2( 3x + 5 ) = 3 - 10x when x = 2
5 - 2( (3*2) + 5 ) = 3 - (10*2)
5 - 2( 6 + 5 ) = 3 - 20
5 - 2*11 = 3 - 20
5 - 22 = 3 - 20
-17 = -17
The numbers are similar on both sides so 2 is a solution
