Answer:

Probability of rolling number 3 = $\frac{1}{6}$

Step-by-step explanation:

Lin has a die with 6 sides.

Each side of the die is labeled with 1, 2, 3, 4, 5 and 6.

Since, probability of rolling any number = $\frac{\text{Favorable event}}{\text{Total number of events}}$

Therefore, probability of rolling number 3 = $\frac{\text{Favorable event}}{\text{Total number of events}}$

Favorable event of getting 3 in single roll = 1

Total events that can happen in one roll = 6

Therefore, probability of rolling number 3 = $\frac{1}{6}$

Cloud [144]

Answer:

Asanji drove for $5$ hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove $= X+3$ hours

Thus, distance travelled by Asanji in $X+3$ hours is equal to distance travelled by Huong in $3$ hours

$45 ( X+3) = 75 (3)\\$

On solving the above equation, we get -

$45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2$

Asanji drove for $3 + 2 = 5$ hours before Huong caught up

Algebra There were 4 times the number of students in fourth grade at the basketball game.How many students attended the basketba

denis-greek [22]

Answer:

200 students attended the basketball game

Step-by-step explanation:

The complete question in the attached figure

Let

x ------> the number of students in fourth grade

s -----> the number of students at the basketball game

we know that

The number of students at the basketball game is four times the number of students in fourth grade

The linear expression is

$s=4x$ -----> equation A

$x=50\ students\ in\ fourth\ grade$ -----> equation B

substitute equation B in equation A and solve for y

$s=4(50)$

$s=200\ students\ at\ the\ basketball\ game$

therefore

200 students attended the basketball game

A pizza has a diameter of 14 inches each piece has a central angle of 30° what is the distance around the outside of the crust t

jonny [76]

Answer:

The distance is 2.33 π

Step-by-step explanation:

First we have to calculate the perimeter of the circle with the following formula:

r = 14in

c = π * 2r

Now we replace the value of r

c = π * 2 * 14

c = π * 28

c = 28π

Now we have to multiply it by 30/360 which is the fraction that represents the arc over the entire circumference

28π * 30/360 = 2 1/3 π = 2.33 π

Find the value of x.

andrezito [222]

X = 57. Use the rules for inscribed angles. If that exterior angle is 123, then its supplement is 57. That 57 degree inscribed angle has an intercepted arc that is also the same arc that angle x intercepts. So x has the same measure as the other inscribed angle. Your answer is B.
