a taco stand sells tacos for $3.25 each. the stand's expenses for the day are $210. definec your variables and write an inequali

AlekseyPX

Okay, we know that the expenses for the day is 210.

Knowing this, and the price of the taco, we write the inequality:

3.25t > 210

t = number of tacos

Now divide both sides by 3.25:

t > 64.62 (rounded)

Because a taco stand can't sell a fraction of a taco, we know that the taco stand has to sell more than 65 tacos for a profit.

A circle has a diameter of 10 centimeters. of a sector with a central angle of 50 degrees is cut out, what is the area of this s

kramer

Answer:

D. 10.91 square centimeters

Step-by-step explanation:

Area of a sector of a circle = $\frac{\theta}{360}\\$ $\pi$ $r^{2}$

where $\theta = 50^{o} C$

radius (r) = half of diameter = 10/2 = 5 cm

Area = $\frac{50}{360} * \frac{22}{7} * 5^{2}$

= 10.91 $cm^{2}$
