mezya [45]

Answer:

3. \displaystyle 1\frac{1}{3} = x

2<em>C.</em> \displaystyle III.

2<em>B.</em> \displaystyle I.

2<em>A.</em> \displaystyle II.

1. \displaystyle Set-Builder\:Notation: [x|7, 0 ≠ x] \\ Interval\:Notation: (-∞, 0) ∪ (0, 7) ∪ (7, ∞)

Step-by-step explanation:

3. <em>See</em><em> </em><em>above</em>.

2<em>C</em>. The keyword is ratio, which signifies division, so you would choose "III.".

2<em>B</em>. The keyword is percent, which signifies multiplication of a ratio by 100, so you would choose "I.".

2<em>A</em>. The keyword is total, which signifies addition, so you would choose "II.".

1. Base this off of the denominator. Knowing that the denominator CANNOT be zero, you will get this:

\displaystyle x^2 - 7x \\ x[x - 7] = 0; 7, 0 = x \\ \\ Set-Builder\:Notation: [x|7, 0 ≠ x] \\ Interval\:Notation: (-∞, 0) ∪ (0, 7) ∪ (7, ∞)

A truck hauls wheat to a storage granary. It carries a total of 4,970 bushels of wheat in 14 trips. How much does the truck haul
Alex17521 [72]

Answer:

355 bushels.

Step-by-step explanation:

To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat  between the total of trips of the truck.

The total amount of bushels is 4970 and the total of trips is 14.

Then, the amount of bushels for each trip would be 4970/14 = 355.

Therefore, the truck hauls 355 bushels of wheat each trip.
