Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space
Tatiana [17]

The rate in

\frac{ {m}^{3} }{ {m}^{2} }  \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so,100 \times 100 \times 100 \: {cm}^{3}  \: in \:  {m}^{3}

To find what is the volume in cubic metres.

\frac{250000}{10000000}  =  \frac{1}{4}  = 0.25 \frac{ {m}^{3} }{ { m}^{2} }

so, the rate is0.25 \frac{ {m}^{3} }{ {m}^{2} }

If the measure of an angle is 27°,find the measure of its supplement.
finlep [7]

Answer:

153°

Step-by-step explanation:

1. If 27° is the supplement of another angle (or vice versa), that means both angles add up to 180.

2. To find the supplement of 27°, we simply subtract that number from 180.

  • 180 - 27
  • 153

Therefore, the supplement of 27° is 153°.
