On a recent day, one U.S dollar was worth 0.64 euros. If you were to exchange 126 euros on that day, how many U.S. dollars would
Dimas [21]

Answer: $196.88

Step-by-step explanation:

It is given that the rate of 1 US dollar = 0.64 euros.

Then, 1 euro = \frac{1}{0.64}\text{ dollars}

⇒ 1 euro =1.5625 dollars

Now, 126 euros = 126\times1.5625

\Rightarrow126\text{euros} =196.875\approx196.88\text{ dollars}

Hence, If we exchange 126 euros on that day, then we would receive 196.88 dollars.

what is the surface area of a triangular pyramid if the base is 12 by 12 and each triangle is 12 by 15?
8_murik_8 [283]

Answer:

504 cm squared

Step-by-step explanation:

To find the surface area, find the area of the square base and add it to the area of each triangle face.

Find the area of the base by multiplying base length by base length.

Here the base is 12 x 12 = 144.

Find the area of each triangle face by multiplying 1/2 * b*h.

Here the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.

Together the surface area is 360 + 144 = 504.
