Answer:

Step-by-step explanation:

count them all together and the right triangles add an additional number of triangles so there are 16 altogether

plus I don't know how you would get the other answers because that is the only one that makes sense if you are including overlapping and stuff because there are technically only 3 triangles actually shown here without taking out any other lines or ignoring them but for your purposes there are 16

A couple plans to have four children. Using a tree diagram , obtain the sample space. List the elements that make up the sample

blagie [28]

<span>Correct answer is B.

There are $2^4 = 16$ points in the sample space, so choices C and D are automatically out.

Choice A is out because there is a possibility to have all 4 boys, but BBBB is not in choice A.

So the answer is choice B</span>

Mary drove from her home to the library after she left the library she drove to the park after that she drove home the map shows

algol [13]

Answer:

24 miles

Step-by-step explanation:

Distance formula (d):

D = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Home to library

(-4, 1) ; (-4, 9)

D1 = sqrt((-4 + 4)^2 + (9 - 1)^2)

D1 = 8

Library to park :

(-4, 9) ; (2, 1)

D1 = sqrt((2 + 4)^2 + (1 - 9)^2)

D3 = 10

Park to home :

(2, 1) ; (-4, 1)

D1 = sqrt((-4 - 2)^2 + (1 - 1)^2)

D2 = 6

Show work for repeated subtraction to divide 35÷4

Sonja [21]

35/4

You'd start by dividing 4 into 3. Since three is smaller it will not work. So you then divide it into 35. 35/4=8.75

Find the probability that the dart lands in the shaded circular region. The radius of the dartboard is 4 in, and the radius of t

PilotLPTM [1.2K]

Answer: The required probability is 0.25.

Step-by-step explanation:

Since we have given that

Radius of the dartboard = 4 in

Area of the dartboard is given by

$\pi r^2=3.14\times (4)^2=3.14\times 16=50.24\ in^2$

Radius of the shaded region = 2 in

Area of shaded region is given by

$\pi r^2=3.14\times (2)^2=12.56\ in^2$

So, the probability that the dart lands in the shaded circular region is given by

$\dfrac{12.56}{50.24}=0.25$

Hence, the required probability is 0.25.

Frank was skiing down big bear mountain. He finished 22% of his skiing in the morning. Then he still had 23.4 miles left. How ma

gtnhenbr [62]

Answer: 6.6 miles

Step-by-step explanation:

Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.

The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:

78% of x = 23.4

0.78 × x = 23.4

0.78x = 23.4

x = 23.4 / 0.78

x = 30 miles

Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:

= 30 - 23.4

= 6.6 miles
