Mathematics

SSSSS [86.1K]3 years ago

Answer:

Step-by-step explanation:

The formula for determining the length of a rectangle is expressed as

Area = length × width

The large rectangle has a length of 10 units and width 5 units. The area of the large rectangle would be

10 × 5 = 50 units²

Inside this rectangle is a smaller rectangle of length 4 units and width 2 units. The area of the smaller rectangle would be

4 × 2 = 8 units²

Probability is expressed as favorable outcome/total number of possible outcomes

The region that is not shaded grey is

50 - 8 = 42 units²

The probability that a point chosen inside the large rectangle is not in the shaded region is

42/50 = 0.84

Converting to percentage, it becomes

0.84 × 100 = 84%

Alexxandr [17]

Answer:

7.8

Step-by-step explanation:

distance formula : d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

where the x and y values are derived from the given points

here the given points are (11,3) and (6,9)

<u>assigning variables</u>

(x1,y1) = (11,3) so x1 = 11 and y1 = 3

(x2,y2) = (6,9) so x2 = 6 and y2 = 9

<u>plugging in values into formula</u>

recall formula d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

==> plug in x1 = 11 , y1 = 3 , x2 = 6 and y2 = 9

d=\sqrt{(6-11)^2+(9-3)^2}

==> subtract values in parenthesis

d=\sqrt{(-5)^2+(6)^2}

==> evaluate exponents

d=\sqrt{25+36}

==> add 25 and 36

d=\sqrt{61}=7.8 ( approximately )

Please help me with this.. and tell correct answer..​
seropon [69]

Answer:

Step-by-step explanation:

55 +80 + ∠C = 180   {Angle  sum property}

135 + ∠C = 180

∠C = 180 - 135

∠C = 45

The side opposite to the biggest angle is the longest side

Biggest angle is ∠B. So the longest side is AC

Smallest angle is ∠C. So, the shortest side is BA
