What is the probability of rolling an odd number with one roll of a number cube.

Mathematics

Answer:

1/2

Step-by-step explanation:

There are 6 sides on a number cube, each labeled with 1,2,3,4,5, and 6.

Out of these, 2,3, and 5 are odd numbers. That's 3.

Probability is the (number of ways the event can occur)/(total number of possible outcomes)

So 3/6=1/2

Area of a triangle with verticals of (-4,1),(-7,5),(0,1)

Lynna [10]

Answer:

$8 ft^2$

Step-by-step explanation:

I assume that the three points given are the vertices of the triangle. So the three points are:

A (-4,1)

B (-7,5)

C (0,1)

The area of a triangle is given by:

$A=\frac{1}{2}bh$

where b is the base and h is the height.

Here we can take as follows:

- We can take the base to be the side AC, so that its length is equal to the distance between the two points:

$AC=\sqrt{(0-(-4))^2+(1-1)^2}=4$

- The height of the triangle is therefore the perpendicular distance between AC and point B. This is equivalent the difference in the x-coordinate between any point on AC and B, so:

$h=(5-1)=4 ft$

Therefore, the area of the triangle is:

$A=\frac{1}{2}(4)(4)=8 ft^2$

1044 fans join a club in the first month after the first month nine new members are allowed to join each month how many members

laiz [17]

Answer:

Total number of members in month 34 is 1341 members.

Step-by-step explanation:

We have given,

Number of fans join a club in first month = 1044

And after the first month nine new members are allowed to join each month.

After first month , Let the number of club members in x months will be given as:

Number of members = 1044 + 9x

We need to find number of members in month 34.

So for first month we already had 1044 members, that mean for remaining 33 months we need to calculate members.

i.e total number of members in month 34 = 1044 + (33×9 ) , {Since x = 33 here}

OR total number of members in month 34 = 1044 + 297 = 1341 members

Use trigonometry to find the missing side. Round your answer to the nearest tenth (one decimal place)

Alchen [17]

Given:

A figure of a right triangle.

To find:

The missing side by using the trigonometric ratios.

Solution:

In a right angle triangle,

$\cos \theta=\dfrac{Adjacent}{Hypotenuse}$

In triangle ABC,

$\cos A=\dfrac{AC}{AB}$

$\cos (31^\circ)=\dfrac{b}{270}$

$0.857=\dfrac{b}{270}$

Multiply both sides by 270.

$0.857\times 270=b$

$231.39=b$

$b\approx 231.4$

Therefore, the missing side length is b=231.4 inches.
