The variable r represents a value in the set (4,6,7,8). Which value of r makes 2(r-4) + 3=7 a true statement?

Answer:

17 units

Step-by-step explanation:

Going from one point to the other, the change in x is 15 and that in y is 8.  Therefore, applying the Pythagorean Theorem,

distance = √(225 + 64) = √289 = 17

The distance between the two points is 17 units.

Answer:

Distance = √(x2 - x1)² + √(y2 - y1)²

Distance = √(7 - (-8))² + √(8 - 0)²

Distance = √(7 + 8)² + √(8)²

Distance = √(15)² + √(8)²

Distance = √(225 + 64)

Distance = √(289)

Distance = 17 unit

Answer:

Step-by-step explanation:

1). By applying Pythagoras theorem in the triangle formed by two sides and the diagonal,

Length of the diagonal = [tex]\sqrt{(\text{side})^2+(\text{side})^2}[/tex]

                                      = [tex](\text{side})\sqrt{2}[/tex]

                                      = 25√2

                                AC ≈ 35.56 units

2). Since, diagonal of a square is the angle bisector of interior angles of the square,

m∠CAB = 45°

By applying sine rule in ΔABC,

sin(45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{AB}{AC}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{25}{AC}[/tex]

AC = 25√2

AC ≈ 35.56 units

Answer: 88 degrees; acute triangle

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).

A factory inspector found flaws in 3 out of 18 wooden boxes. What is the experimental probability that the next wooden box will be flawed?

Write your answer as a fraction or whole number.

-------------------------------------------------------------------------------------------------------------

Remember, The experimental probability is the number of times an event occurs out of the total number of trials.

-------------------------------------------------------------------------------------------------------------

Flawed Boxes / Total

=3/18

=1/6

So The Answer is 1/6

The experimental probability that the next wooden box will be flawed is 1/6=0.167.

The experimental probability of an event is the ratio of the number of outcomes in which a specified events occurs to the total trials.

Mathematically, Experimental probability= f/n, where f is the number of times an event occurs, n is the total number of trials.

Total number of wooden boxes= 18

Total number of boxes that are flawed= 3

Therefore, required experimental probability = 3/18

                                                           =1/6

Hence, the experimental probability that the next wooden box will be flawed= 1/6
