4. Use the diagram below to answer the question
ludmilkaskok [199]

Answer:

≈ 397 m

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Let h represent the height of the balloon above ground, then

h² + 50² = 400², that is

h² + 2500 = 160000 ( subtract 2500 from both sides )

h² = 157500 ( take the square root of both sides )

h ≈ 397 m ( to the nearest metre )

Mozart's Music Store rents trombones for $34 a month. Bach's Music Store rents trombones for $30 per month plus a yearly fee of
jeka94

Answer:

Step-by-step explanation:

Let M(x) be the cost of renting from Mozart's Music Store for x years, and B(x) be the cost of renting from Bach's Music Store for x years.

From the problem statement, we can come up with the following equations:

M(x) = 34(12x)

B(x) = 30(12x) + 48x

Plugging in x = 9 for each equation, we can get the answer:

M(9) = 34(12 * 9)

M(9) = 34(108)

M(9) = 3672

B(9) = 30(12 * 9) + 48(9)

B(9) = 30(108) + 432

B(9) = 3240 + 432

B(9) = 3672

From this, we can see that the value is equal for both stores.
