Answers

Answer 1
Answer: I would think that the answer is C because her distance is always increasing as long as shes moving, it isn't asking for direction, so no matter if she goes forward then backwards then forwards again she has still traveled that distance, so I believe its C because you can't go negative distance, even if you go backwards

What is the perimeter of the figure to the nearest tenth of a millimeter?



A.
9.4 millimeters

B.
12.0 millimeters

C.
21.4 millimeters

D.
30.8 millimeters

Answers

We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters.

Which equation could be used to solve problems involving the relationships between the angles?A) 90 + (8a + 9) = (11 + 2a)
B) 90 − (8a + 9) = (11 + 2a)
C) (11 + 2a) − 90 = (8a + 9)
D) (8a + 9) − (11 + 2a) = 90

Answers

Answer:

B

Step-by-step explanation:

Seeing the above angles we conclude that

(11+2a)+(8a+9)=90 (since they are complementary angles)

So

Subtracting (8a+9) to both sides we get

90-(8a+9)=11+2a

Answer:

The answer is B.) 90 - (8a + 9) = (11 + 2a)

Step-by-step explanation:

90 − (8a + 9) = (11 + 2a)

Complementary angles add to 90°

At MLC 1/8 of the girls are boarders. There are 300 boarders.a) How many girls are not boarders?
b)How many students are there at MLC?

Answers

Multiply 300 from both numerator and denominator of (1)/(8)

(1)/(8) = (300)/(2400)

2400 - 300=2100

2100 girls are not boarders.

2400 + 300 = 2700

2700 students are there at MLC

Answer:b
