Rina8888 [55]2 years ago
4 0

Step-by-step explanation:

there is a rectangle and an octagon within

area of rectangle = 8*9 = 72

there are 4 right angled triangles

area of one such triangle = .5 × 9 = 4.5

total area of triangles = 18

area of octagon = 72-18 = 54 m^2

A "thrift" is another name for a commercial bank. True or False
elixir [45]

A thrift is a kind of bank that arranges mortgages (mostly for home ownership) and sets up accounts to receive deposits.

The statement is actually false. The difference is in who they can borrow from and whether or not they are set up for profit. Thrifts are usually non profit.

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that form
anyanavicka [17]

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees

<h3>How to determine the central angle?</h3>

The given parameters are:

  • Area = 75π cm^2
  • Radius, r = 15 cm

The area is calculated using

Area = α/360 * πr^2

So, we have:

α/360 * π * 15^2 = 75π

Evaluate the exponent

α/360 * π * 225 = 75π

Divide both sides by 75π

α/360 * 3 = 1

Multiply

α/120  = 1

Multiply both sides by 120

α = 120

Hence, the measure of the central angle that forms the sector is 120 degrees

Please help I don’t understand
puteri [66]

Answer:

It would be the first equation that has a higher initial start. (d = -50t + 70)

Step-by-step explanation:

This is because 70 is greater than 65. Assuming that the 65 is the distance, we can say that the first equation has a higher initial start, that of 70 miles from destination, while the second equation starts from 65 miles from destination.

The negative for the 50 and 60 is counting down the amount of miles until the destination is reached.
