Yeah it’s $214 because it’s monthly

Answer:

The total monthly cost would be $214

Step-by-step explanation:

This is rather simple. They gave us 1,250, which is half of 2,500. Simple multiplication:

1,250 = 2,500

107 = x

2 × 1,250 = 2,500

2 × 107 = 214

Therefore, the total monthly cost if the cell phone is used for 2,500 minutes is $214.

Rampur Sarpanch requested one of his villager to donate a 6m wide land adjusted to his 132.8m long side of his right triangular

Ronch [10]

Answer:

Area of the remaining triangle with the villager is 1243.13 m²

Step-by-step explanation:

Triangle ABC is the triangular plot of a villager shown in the figure attached.

Sarpanch requested the villager to donate land which is 6 m wide and along the side AC which measures 132.8m.

Other sides of the plot has been given as AB = 50m and BC = 123 m.

Now area of this land before donation = $\frac{1}{2}\times {\text{Height}}\times \taxt{Base}$

= $\frac{1}{2}\times (123)\times (50)$

= 3075 square meter

After donation of the land the triangle formed is ΔDBE.

In ΔABC,

$tan(ABC)=(\frac{AB}{BC})$

tan(∠ABC) = $\frac{50}{123}$

= 0.4065

∠ABC = $tan^{-1}(0.4065)$

= 22.12°

In ΔEFC,

tanC = $\frac{EF}{CF}$

0.4065 = $\frac{6}{CF}$

CF = $\frac{6}{0.4065}$

CF = 14.76 m

Since DE = AC - (CF + AG)

= 132.8 - (2×14.76)

= 132.8 - 29.52

= 102.48 m

Now in ΔDBE,

sin(∠DEB) = $\frac{BE}{DE}$

sin(22.12) = $\frac{BE}{102.48}$

DB = 102.48×0.3765

= 38.59 m

Similarly, cos(22.12) = $\frac{BE}{DE}$

0.9264 = $\frac{BE}{102.48}$

BE = 102.48×0.9264

= 94.94m

Now area of ΔDBE = $\frac{1}{2}(DB)(BE)$

= $\frac{1}{2}(38.59)(94.94)$

= 1831.87 square meter

Area of remaining triangle with the villager = Area of ΔABC - Area of ΔDBE

= 3075 - 1831.87

= 1243.13 square meter

Answer:

1/16

Step-by-step explanation:

2^-4

We know that a^ -b = 1/ a^b

2^-4 = 1/2^4

2^4 =16

so 1/2^4 = 1/16

Tim and Tom are painters. Tim and Tom use a liters of paint on a large shipping crate. If the next crate they need to paint is s

antiseptic1488 [7]

This is the concept algebra.
Volume of of paint that is required to paint large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.
