Answer: OPTION B

Step-by-step explanation:

You can find the distance between two points by using the following formula:

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

Given the points  (-2,-6) and (0,5), you can identify that:

x_2=-2\\x_1=0\\\\y_2=-6\\y_1=5

Therefore, substituting values, you get that the distance between those points is:

 d=\sqrt{(-2-0)^2+(-6-5)^2}\\\\d=5\sqrt{5}

Answer:

The correct answer is option A.  √5

Step-by-step explanation:

<u>Points to remember</u>

<u>Distance formula</u>

The distance between two points (x1, y1) and (x2, y2) is given by

Distance = √(x2 - x1)² + (y2 - y1)²]

<u>To find the distance between given points</u>

Here (x1, y1) = (-2, 6) and (x2, y2) = (0, 5)

Distance = √(x2 - x1)² + (y2 - y1)²]

 = √(0 -  -2)² + (5 - 6)²]

 =  √(2² + 1²)]

 = √(4 +1)

 = √5

The correct answer is option A.  √5

Simora [160]

Answer:

1356cm3

Step-by-step explanation:

when the stone is dropped in to the water the new height is 17.4cm(14+3.4)

find the volume when the height is 14cm and when the height is 17.4cm

24*14*17.4=4716

24*14*14=3360

then subtract the two volumes

4716-3360=1356cm3

At homecoming, 125 tickets where sold. Tickets purchased for homecoming cost $20.5 without an activity card, and $15.75 with an
ale4655 [162]

Answer:

Nearly 83 students did not had activity card.

Nearly 42 students had an activity card.

Step-by-step explanation:

Total number of tickets sold at homecoming = 125

Cost of each  ticket without activity card = $20.5

Cost of each  ticket with activity card = $15.75

Total amount earned  = $2365

Let, the number of tickets sold without activity car d  = k

So, the number of tickets sold without card = (Total sold - k)

                                                                          = 125 - k

Now, according to the question:

$20.5(k) + $15.75(125 - k)  =  $2365

or, 20.5 k + 1968.5 - 15.75 k = 2365

⇒ 4.75 k = 2365 - 1968.5 = 396.5

⇒ k = \frac{396.5}{4.75 }  = 83.47

Hence, nearly 83 students did not had activity card.

So,the number of students that had activity card = 125 - 83.47 = 41.53 ~  42

Hence, nearly 42 students had an activity card.
