Answer:

182 m²

Step-by-step explanation:

The formula for surface area of a rectangular prism is;

Surface Area = 2(wl) + 2(lh) + 2(hw) where w is the width, l is the length and h is the height.

SA = 2(2 * 17)m² + 2(17 * 3)m² + 2(3 * 2)m²

     = 2(34)m² + 2(51)m² + 2(6)m²

     = 68 m²  + 102 m² + 12 m²

     = 182 m²

Find the with of a triangle as a 15 cm high in a hypogynous of a 19 cm​
Inessa05 [86]

Answer:

This other side of the triangle is equal to about 11.7 cm

Step-by-step explanation:

In order to find out the third side of the triangle we will just use the Pythagoras Theorem.

c^{2} =a^{2} + b^{2}

Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...

c^{2} =a^{2} + b^{2}\\19^{2} = 15^{2} + b^{2}\\361 = 225 + b^{2} \\

b^{2} = 361 - 225\\b^{2} = 136\\b = \sqrt{136} \\

And so b ≈ 11.66190

Marco wants to buy a new smartphone that costs $495, with some additional accessories. He has already saved $75. Write and solve
antoniya [11.8K]

Marco needs to save a minimum of $420 more to buy a smartphone.

<u>Explanation:</u>

Cost of a smartphone = $495

Savings = $75

Least amount of money, m that needs to be saved = ?

Additional savings, m = Total - initial savings

                              m = $495 - $75

                              m = $420

The inequality equation would be 75 + m ≥ 495

Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
