P(A and B) means add A and B

if both A and B are both greater then 1/2

then when they are added they will always be greater than 1

Answer:

4

Step-by-step explanation:

We can do this problem by doing the absolute value of the difference between 2 and -2.

2-(-2)=4. Absolute value of 4 is 4.

Answer:

54

Step-by-step explanation:

Answer: You will pay $510 for a item with original price of $600 when discounted 15%.

Options:

a) If corresponding pairs of sides and corresponding pairs of angles of two triangles are congruent, then the triangles can be matched up exactly using rigid motions.

b) If two triangles can be matched up exactly using rigid motions, then the corresponding pairs of sides and corresponding pairs of angles of the triangles are congruent.

c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

d) If corresponding pairs of sides and corresponding pairs of angles of two triangles are not congruent, then the triangles are not congruent.

Answer:

c) Two triangles can be matched up exactly using rigid motions if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

Step-by-step explanation:

For both pairs of triangles, what you proved is how to use rigid motions (i.e. rigid transformations) to make congruent shapes.

When rigid transformation is applied to a shape, the image (i.e. result) of the  transformation produces an exact shape (i.e. equal corresponding angles and corresponding sides), meaning that the side lengths and the angles of the preimage (before transformation) and the image (after transformation) is unaltered.

Option (c) is true

Answer:

I would say C or B

Answer:

5.25 miles per minute

Step-by-step explanation:

420/80 = 5.25 so it is 5.25 miles per minute as it is 80 minutes

Answer:

Option C

Step-by-step explanation:

We will analyze the figure and note down the properties given in the figure,

1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.

m(arc LJK) = m(arc LK) = 180°

2). m(∠JKL) = 28°

Therefore, by the property inscribed angle and intercepted arcs,

Intercepted arc (JL) = 2 × (Inscribed angle JKL)

m(arc JL) = 2(26°)

               = 52°

Now we will use these two points to get the measure of arc JK.

m(arc JK) + m(arc LK) + m(arc JL) = 360°

m(arc JK) + 180° + 52° = 360°

m(arc JK) = 360° - 232°

                = 128°

Option C will be the correct option.

Answer:

1) x = 36

2) x = 127

3) x = 36

Step-by-step explanation:

1)

x + 144 = 180

x = 36

2)

15 + x + 38 = 180

x + 53 = 180

x = 127

3)

2x + 16 + 92 = 180

2x + 108 = 180

2x = 72

x = 36

Answer:

First, there are  

3

numbers (6, 7, 8) greater than  

5

on a spinner numbered  

1

-

8

(1, 2, 3, 4, 5, 6, 7, 8). Therefore, there is a:

8

probability of spinning a number greater than  

5

.

However, there is only a 50-50 or  

1

2

chance of tossing a tail on a coin.

Therefore the probability of spinning a number greater than  

5

AND tossing a tail is:

Answer:

option B should be correct

Answer:

x = 24

Step-by-step explanation:

x = .4(60)

x = 24

40% of 60 can be found by converting 40% to a decimal and multiplying it by 60.

40% = 0.4

60x0.4=2.4

Now move the decimal point right one.

So x is 24.

Answer:

range

Step-by-step explanation:

The difference between the lowest and the highest number is called the range. The middle value is the median (it's in the "mid"dle, median) The mean is the average. And the mode is the most frequent value.
