Answer:

 5 , 7 , 8 represent the side of acute angled triangle

Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that:

Set of numbers.

Now, We use the following result:

When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.

First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.

if sum > Square of last side ⇒ it is Acute Triangle

if sum = Square of last side ⇒ it is Right Triangle

if sum < Square of last side ⇒ it is Obtuse Triangle  

a). 4  , 5 , 7

4² = 16 ,  5² = 25 , 7² = 49

16 + 25 = 41

Hence, 41 < 49

⇒ It is an Obtuse Triangle.

b). 5 , 7 , 8

5² = 25 , 7² = 49 , 8² = 64

25 + 49 = 74

Hence, 74 > 64

⇒ It is an acute Triangle.

c). 6 , 7 , 10

6² = 36 , 7² = 49 , 10² = 100

36 + 49 = 85

Hence, 85 < 100

⇒ It is an Obtuse Triangle.

d). 7 , 9 , 12

7² = 49 , 9² = 81 , 12² = 144

49 + 81 = 130

Hence, 130 < 144

⇒ It is an Obtuse Triangle.

Therefore, Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

Answer:

a. .02 * .02 = .0004  

b. (1 - .02 - .19) = .79; .79*.79 = .6241

Step-by-step explanation:

The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Probability that the bus will be late is 0.19

Probability that the bus will be early is 0.02.

The probability that the bus will arrive early next two days is

= 0.02 * 0.02

=0.0004

The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.

The probability that the bus will arrive on time next two days

= (1 - 0.02 -0.19) = 0.79

The probability that the bus will come on time is more as the probability of coming early or late is less.

Step-by-step explanation:

You can think of 24 as 24/1 so

24 X 1/6

and to multiply two fractions you multiply the numerators and denominators so

24 * 1/6

Now you can divide 6 into 24 and get 4.

Answer:

X= -3+y

Step-by-step explanation:

The value of the rational expression when x is equal to 4 is 3.

Option C is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

To find the value of the rational expression (x + 20)/(x + 4) when x is equal to 4,

We substitute 4 for x in the expression:

(4 + 20)/(4 + 4)

= 24/8

= 3

Therefore,

The value of the rational expression when x is equal to 4 is 3.

Step-by-step explanation:

for it to be a right triangle you should be able to add two of the sides and it be greater than the third side. 7 + 24 > 25

24 + 25 > 7

7 + 25 > 24 therefore it is indeed a right triangle

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

Answer:

[tex]Side_2 = 74\ in[/tex]

Step-by-step explanation:

Given

[tex]Side_1= 82\ in[/tex]

[tex]Area = 6068\ in^2[/tex]

Required

Determine the length of the other side

For a rectangle:

[tex]Area = Side_1 * Side_2[/tex]

This gives:

[tex]6068\ in^2 = 82\ in * Side_2[/tex]

Divide both sides by 82in

[tex]\frac{6068\ in^2}{82\ in} = \frac{82\ in}{82\ in} * Side_2[/tex]

[tex]\frac{6068\ in^2}{82\ in} = Side_2[/tex]

[tex]Side_2 = \frac{6068\ in^2}{82\ in}[/tex]

[tex]Side_2 = 74\ in[/tex]

Hence, the length of the other side is 74 inches
