Answer: 8 textbooks

Step-by-step explanation:

Sold 40 notebooks = 40 x $4 = $160

$800 - $160 = $640 left to sell

$640/$80 (cost of textbook) = 8 textbooks need to be sold

luda_lava [24]

Answer: C

Step-by-step explanation:

This describes an expotential function

At t = 0, P = 70

Therefore, C = 70

P = 70 e^kt

Solve for k by plugging in (4,360)

k = 0.4094

plug in t(7 hours)

70 e^(0.4094*7)

The answer roughly equals C

How many solutions does the equation -4x + 6 = 6x -2 have
SpyIntel [72]

Answer:

One.

Step-by-step explanation:

-4x + 6 = 6x - 2

-4x - 6x = -2 - 6

-10x = -8

There's only value of x which, when multiplied by -10 would produce -8.

That value is 0.8.

-10 * 0.8 = -8

No other value can produce the same result.

This means that there's only one solution.

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
