Answer:

124 ft2

Step-by-step explanation:

The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.

Answer:

(6, - 4 )

Step-by-step explanation:

Given the 2 equations

$\frac{x}{4}$ - $\frac{3}{8}$ y = 3 → (1)

$\frac{5}{3}$ x - $\frac{y}{2}$ = 12 → (2)

Multiply (1) by 8 and (2) by 6 to clear the fractions

2x - 3y = 24 → (3)

10x - 3y = 72 → (4)

Rearrange (3) expressing - 3y in terms of x by subtracting 2x from both sides

- 3y = 24 - 2x

Substitute 3y = 24 - 2x into (4)

10x + 24 - 2x = 72, that is

8x + 24 = 72 ( subtract 24 from both sides )

8x = 48 ( divide both sides by 8 )

x = 6

Substitute x = 6 in either (3) or (4) and solve for y

Substituting in (3)

2(6) - 3y = 24

12 - 3y = 24 ( subtract 12 from both sides )

- 3y = 12 ( divide both sides by - 3 )

y = - 4

Solution is (6, - 4 )

A train 100 m long crosses a pole in 5 seconds.Find the speed of the train in kilometre per hour.

In-s [12.5K]

Answer:

$\sf72 km/h$

Step-by-step explanation:

Distance covered by the train in crossing the pole = 100 m.

$\sf Time \: taken=5 \: seconds$

$\sf \: Speed \: of \: the \: train = \frac{Distance }{Time}$

$\sf = \frac{100}{5} \: m/s$

$\sf \: = 20 \: m/s$

$\sf \: = 20 \times \frac{18}{5} \: km/h$

$\sf = 72 \: km/h$

Hence, the speed of the train is 72 km/h
