What is the distance to the nearest tenth of a unit between point H ( -4,6 ) and point I ( 2,-3 )

Answers

Answer:

10.81 units

Step-by-step explanation:

Given data

point H ( -4,6 ) and point I ( 2,-3 )

x1= -4

y1=6

x2= 2

y2=-3

The formula for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(-3-6)²)

d= √(2+4)²+(-9)²)

d= √(6)²+(-9)²)

d= √36+81

d=√117

d= 10.81 units

Hence the distance between the points is 10.81 units

Answer:

  a) Cat

  b) 8

  c) 6

Step-by-step explanation:

a) Each line contains one large square, at least. The smallest additional area is on the Cat line. Apparently, the fewest people preferred cats.

__

b) The smaller symbols appear to represent 1/4, 1/2, and 3/4 of the larger square. On that basis, we can add all of the symbols to discover there are a total of 10 of them:

  1 1/4 +1 3/4 +2 1/2 +1 1/2 + 3 = 8 + (1/4 +3/4) +(1/2 +1/2) = 8 +1 +1 = 10

Since 10 symbols represent 80 people, each large square symbol must represent 8 people.

__

c) The number preferring dogs is (1 3/4)(8) = 14. The number preferring giraffes is (2 1/2)(8) = 20. Then 20 -14 = 6 more people preferred giraffes.

Bob has a coin cup with four $1 tokens and two $5 tokens in it. He also has two $10 tokens and one $25 token in his pocket.
He randomly draws a token froin the cup, and then randomly draws a token from his pocket. What is the probability that he
will draw $30 in tokens?
OB.
. В

Answers

We want to find the probability that Bob will randomly draw $30 in tokens. We will find that the probability is P = 1/6 = 0.167

Finding the probability.

The only case where he draws $30 randomly is when:

He takes one $5 token from the coin cupHe takes the $25 token from his pocket.

Then we need to find the probabilities for these two events.

For the first one, the probability will be equal to the quotient between the number of $5 tokens and the total number of tokens in the cup. There are 6 tokens in the cup and 2 of these are $5 tokens, then the probability is:

p = 2/6 = 1/3

For the second event the probability is computed in the same way, he has two tokens in his pocket and one of them is a $25 token, then the probability is:

q = 1/2

The joint probability, the probability that both of these events happen at the same time, is given by the product of the individual probabilities, so we get:

P = p*q = (1/3)*(1/2) = 1/6 = 0.167

So the probability that he draws $30 in tokens is P = 1/6 = 0.167.

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?

Answers

Answer:

As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.

Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.

Subtract the 2 hours from 10am:

= 10 - 2

= 8am

Subtract the 15 minutes from 45:

= 45 - 15

= 30

Put that together:

= 8:30 am

They left their house at 8:30 am using this scenario.
