A playground measures 300 m × 170 m.Find the cost of planting grass on this at the rate of Rs 80 per hectare.

Ierofanga [76]

<h2><u>Answer</u> :-</h2>

To find the cost of planting grass , we have to find area of the field.

Area of field = Length × Breadth

${= 300×170}$

${=51000 sq. m}$

Now convert into hectare.

1 hectare = 10000m sq.

51000 / 10000

So area field = 5.1 hectare sq.

Now cost = 5.1 x 0.80 p

${= 0.408 p}$

lucas divides his pizza into three equal pieces for himself and his two friends. his friend teddy eats 5/8 of his piece for lunc

Marina CMI [18]

Answer:

He ate $\frac{1}{20}$ of the original pizza for dinner

Step-by-step explanation:

- Lucas divides his pizza into three equal pieces for himself and his two

friends

∵ There are 1 pizza

∵ It is divided into 3 equal parts

∴ Each part is $\frac{1}{3}$

∴ Teddy takes $\frac{1}{3}$ of the pizza

- Teddy eats $\frac{5}{8}$ of his piece for lunch and a further $\frac{2}{5}$ of what

remains for dinner

∵ His piece is $\frac{1}{3}$

∵ He eats $\frac{5}{8}$ of his piece for lunch

∴ He eats for lunch = $\frac{5}{8}$ × $\frac{1}{3}$ = $\frac{5}{24}$

- Let us find the remaining of his piece for dinner

∵ The remaining = $\frac{1}{3}$ - $\frac{5}{24}$

- Make L.C.M for the denominators

∵ The L.C.M of 3 and 24 is 24

∵ $\frac{1}{3}$ = $\frac{1*8}{3*8}$ = $\frac{8}{24}$

∴ The remaining = $\frac{8}{24}$ - $\frac{5}{24}$

∴ The remaining = $\frac{3}{24}$ = $\frac{1}{8}$

∵ He ate $\frac{2}{5}$ of the remaining for dinner

∵ The remaining of his piece = $\frac{1}{8}$

∴ He ate for dinner ⇒ $\frac{2}{5}$ × $\frac{1}{8}$

∴ He ate for dinner ⇒ $\frac{2}{40}$ = $\frac{1}{20}$

* He ate $\frac{1}{20}$ of the original pizza for dinner

Dr. Shah visits patients at their homes. The equation y = 150x + 50 represents the amount

Veronika [31]

Answer:

50

Step-by-step explanation:

The equation that represent the total cost is in form of equation of a line y = mx+c

m is the gradient of the line

c is the intercept (The point where the line cuts the y - axis

If the equation given y = 150x + 50 is graphed, it will look like a straight line and the y- intercept will represent 50 when compared with the general equation of a line.

A block of copper weighs 2160g and has a volume of 240cm3. what is the density of the copper?

densk [106]

The unit of density [kgm^-3] displays the formula.
So density=mass/volume.

Convert 2160g into kilograms [2160/1000=2.160kg]
Convert volume of 240cm^3 into m^3
100cm=1m
100x100x100=1000000cm^3=1m^3
240/1000000=[2.4x10^-4]

Final calculation
2.160/2.4x10^-4=9000

Answer: 9000kgm^-3
