Answer:
$310
Step-by-step explanation:
The first step is to add the costs of the textbook together :
$68.41 + $105.35 + $72.49 + $59.91 = $306.16
In order to round off to the nearest ten dollars, look at the units figure, if the number is greater or equal to 5, add 1 to the ten figure. If this is not the case, add zero. Replace the unit digit with zero
The unit digit is greater than 6, so 1 is added to the tens digit. The amount becomes $310

Answer:
∠ DAB = 133°
Step-by-step explanation:
In a parallelogram ABCD, the opposite angles are equal. That means ∠ A = ∠ C and ∠ B = ∠ D.
Now, it is given that ∠ D = 3x + 17 and ∠ B = 5x - 3
So, 3x + 17 = 5x - 3
⇒ 2x = 20
⇒ x = 10
Therefore, ∠ B = 5x - 3 = 50 - 3 = 47°
Now, we know that in a parallelogram the adjacent angles are supplementary i.e. ∠ A + ∠ B = 180°
⇒ ∠ A = 180 - ∠ B = 180° - 47° = 133°
Therefore, ∠ DAB = 133° (Answer)
Distribute (2x+y) throughout (4x^2-2xy+y^2). You should get
8x^3-4x^2y+2xy^2+4x^2y-2xy^2+y^3
Simplify and collect like terms and you should get 8x^3+y^3
99 boys and 1 girl makes 99 percent of boys. To make it 98%, 50 boys must leave the theatre, so there are 49 boys and 1 girl, making 98% of boys.
