Two dice are thrown simultaneously find

Mathematics
1 answer:
STALIN [3.7K]3 years ago
4 0

Answer:

13.89%

Step-by-step explanation:

First lets find all possibilities of two dice being thrown, we can do this by finding a simple dice chart online (I attached an image of one to help.)

There are 36 possibilities, and we need to find how often the two dice add together to equal eight. 6+2=8, 5+3=8, etc.

There are five 5 total times that two dice can equal eight. so 5 out of 36 times we roll two dice we'll get eight.

\frac{5}{36}

Type that into the ol' handy dandy calculator and we've got 0.1388888889. So... a lot of 8's, we don't need that many and we just can't have an answer with that many.

To make that number into a percentage we have to move the dot two spaces over, and round to the thousandths place (two numbers).

This would give us 13.89%, our final answer.

Hope this helped!

A circle is characterized by radius, arc, sectors and circumference

  • The length of the major arc is 18.75\pi
  • The radius of the circle is 15
  • The area of the shaded sector is 140.625 * \pi

<h3>Length of the major arc</h3>

The given parameters are:

C = 30\pi --- the circumference

\theta = 225^o -- the center angle

The length of the major arc is calculated using:

L = \frac{\theta}{360} * C

So, we have:

L = \frac{225}{360} *30\pi

Evaluate

L = 18.75\pi

Hence, the length of the major arc is 18.75\pi

<h3>The radius of the circle</h3>

The circumference is given as:

C = 30\pi

So, we have:

2\pi r = 30\pi

Divide through by 2pi

r = 15

Hence, the radius of the circle is 15

<h3>The area of the shaded sector</h3>

The area of a sector is:

A = \frac{\theta}{360} * \pi r^2

So, we have:

A = \frac{225}{360} * \pi * 15^2

Evaluate

A = 140.625 * \pi

Hence, the area of the shaded sector is 140.625 * \pi

A truck can be rented from Company A for ​$140 a day plus ​$0.80 per mile. Company B charges ​$80 a day plus ​$0.90 per mile to
natta225 [31]

Answer:

600 miles in a day.

Step-by-step explanation:

Variable x = number of miles

Company A: 140 + 0.80x

Company B: 80 + 0.90x

Set up an equation:

140 + 0.80x = 80 + 0.90x

Isolate variable x:

60 + 0.80x = 0.90x

60 = 0.10x

600 = x

Check your work:

140 + 0.80(600) = 80 + 0.90(600)

140 + 480 = 80 + 540

620 = 620

Correct!
