Probability of rolling a 1 = 1/6
Probability of rolling a 1 = 1/6

Multiply these together (1/6)x(1/6) to get your probability that this will occur twice in a row.

(1/6)X(1/6)=0.02777777778 (the 7 is repeating)

This rounds up to 2.8% chance, or 2.78% (depends on what decimal place you have to round it to)

What is the radius of a circle with an area of 50.24 cubic inches? Use 3.14 for pi. Enter your answer in the box.
miss Akunina [59]

Answer:

r=4

Step-by-step explanation:

Area of a circle is

A = pi* r^2

We know the area and 3.14 = pi

50.24 = 3.14 * r^2

Divide each side by 3.14

50.24/3.14 =3.14 /3.14 *r^2

16 = r^2

Take the square root of each side

sqrt(16) = sqrt(r^2)

4 =r

GIVING BRAINLIEST PLEASE HELP How many triangles can you make with side lengths of 3mm, 7mm, and 4.69mm? (explain in words or nu
DanielleElmas [232]

Answer:

  1

Step-by-step explanation:

Three side lengths that meet the requirements of the triangle inequality will form exactly one triangle.

_____

The triangle inequality requires the sum of the short sides be at least as long as the long side. Here, we have 3 + 4.69 = 7.69 > 7, so we satisfy the triangle inequality.

The side lengths can be arranged in clockwise or counterclockwise order, least to greatest. Each triangle is a reflection of the other, so they are considered to be the same triangle (congruent).

Please help I dont get it<br> x - 3 1/2 = 8.5
Vlad1618 [11]

Answer:

12

Step-by-step explanation:

x - 3\frac{1}{2} = 8.5          

x - \frac{7}{2} = 8.5         Convert the mixed fraction to a imroper fraction.

x - 3.5 = 8.5     Convert the improper fraction to a decimal number.

x = 12                Add 3.5 to both sides.
