10. A taco stand sells tacos for $3.25 each. The stand’s expenses for the day are $210. Define your variables and write an inequ
Tasya [4]
In order for the profit to be zero, the quantity of tacos produced must be greater than 210/3.25 = 64.615.

Therefore a small profit will be made when 65 tacos are produced, to wit: 

3.25*65 = 211.25, less costs of $210, yields a profit of 1.25 on a quantity of 65 tacos

To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, mea
Vikki [24]
Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
     tan\:26^{\circ} =\frac{AE}{120}
So, 
     AE=120\:tan\:26^{\circ}
     AE=58.53\:

Therefore, the overall height of the pole is 
     AB=58.53+8=66.53\:feet

The height of the pole is 66.53 feet.

What is the discriminant of the quadratic equation 0 = 2x2 3x – 5?
a_sh-v [17]
If you would like to find the discriminant of the quadratic equation 0 = 2x^2 + 3x - 5, you can do this using the following steps:

<span>0 = 2x^2 + 3x - 5
0 = ax^2 + bx + c
a = 2, b = 3, c = - 5

</span>D = b^2 - 4 * a * c = 3^2 - 4 * 2 * (-5) = 9 + 40 = 49

The correct result would be 49.

7. A coin is tossed and a day of the week is selected. What is the probability that you get tails and a day that begins with "S"
Mrrafil [7]

Answer:

1/7

Step-by-step explanation:

Lets start with the probability of flipping tails, 1/2.

Then the probability of the day starting with the letter s, 2/7.

Calculate the final probability by multiplying the two together.

\frac{1}{2}*\frac{2}{7}=\frac{2}{14}

You can simplify 2/14 down to 1/7
