A straight line is 180° and this is less than that but it’s more than 90°, 105° is close to 90 and this is a bit bigger so your best estimate is

B.) 180°

B. 150

105 is too small/close of an angle to a right angle
60 is an acute angle
and 210 is to large of an angle, it would be larger than a straight line

Morgan jogged51.2kilometersin one weekkelly jogged6 less whats my answer

Andrei [34K]

If you would like to know how many kilometers did Kelly jog that week, you can calculate this using the following steps:

Morgan: 51.2 kilometers
Kelly: Morgan - 6 kilometers = 51.2 - 6 = 45.2 kilometers

The correct result would be 45.2 kilometers.

Part A: Determine if the expression is one of our special products. If so, identify it by its general form:

kondaur [170]

Answer:

Part A: Yes, it is (a - b)².

Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.

Part C: x² - 12x + 36.

Part A: Not a special product.

Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.

Part C: x² + 9x + 8.

Part A: Yes, it is (a + b)²

Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.

Part C: 9x² + 12x + 4.

Part A: Yes, it is (a + b)(a - b), a difference of squares.

Part B: a² - b² => 4x² - 49

Part C: 4x² - 49

Part A: Not a special product.

Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.

Part C: 2x² - 15x + 25

Christian wants to make an A in his class. There are 5 exams this year, and he has taken 4 of them. His grades were 84, 88, 95,

ioda

Answer:

last test grade=x x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79

P.S. If it was helpful please consider giving me brainliest. =)
