Answer:

94

Step-by-step explanation:

Average = Total / Number of Data

70 \times 4 = 280

You have a total of 280 points after 4 quizzes.

4+4=8 quizzes in total

Total you need for average to be 82

82 \times 8 = 656

Number of points you need to hit required:

656 - 280 = 376

You need 376 points in total for the next 4 quizzes.

376  \div 4 = 94

You need an average of 94 points on the next 4 quizzes.

Point A is located at (-2, -6) and is translated 4 units up. What are the coordinates of point A'?
gavmur [86]
Its A because the vertical line is the y-axis so 4+-6 is -2 and the x-axis would remain the same. <span>#TeamAlvaxic</span>

In ΔCDE, \text{m}\angle C = (4x-16)^{\circ}m∠C=(4x−16) ∘ , \text{m}\angle D = (6x-1)^{\circ}m∠D=(6x−1) ∘ , and \text{m}\angle E
borishaifa [10]

Answer:

m∠C = 44°

Step-by-step explanation:

In ΔCDE,

m∠C=(4x−16) ∘

m∠D=(6x−1) ∘

m∠E=(4x−13) ∘ .

The sum of angles in a triangle = 180°

Step 1

We solve for x

m∠C + m∠D + m∠E

(4x−16)° + (6x−1)° + (4x−13)° = 180°

4x - 16 + 6x - 1 + 4x - 13 = 180°

4x + 6x + 4x -16 - 1 - 13 = 180°

14x - 30 = 180°

14x = 180+ 30

14x = 210

x = 210/14

x = 15

Step 2

Find m∠C

m∠C = (4x−16)°

m∠C = (4 × 15 - 16)°

m∠C = (60 - 16)°

m∠C = 44°
