48/60 = .8

This means 80% of 60 is equal to 48.

Thus, a0% = 80%

and we can determine that a = 8.

Two fair number cubes are rolled. What is the probability the numbers are equal or the sum is odd?

Marat540 [252]

Answer:

0.6667 = 66.67%

Step-by-step explanation:

If each number cube has 6 numbers, the two cubes have a total of 6 * 6 = 36 results.

To have equal numbers in each cube, the cases are:

(1,1), (2,2), (3,3), (4,4), (5,5), (6,6) -> 6 cases

To have a odd sum, the cases are:

(1,2), (1,4), (1,6),

(2,1), (2,3), (2,5),

(3,2), (3,4), (3,6),

(4,1), (4,3), (4,5),

(5,2), (5,4), (5,6),

(6,1), (6,3), (6,5). -> 18 cases

So we have a total of 18 + 6 = 24 cases, then the probability is:

P = 24 / 36 = 0.6667 = 66.67%

The radius of a circle 6 cm what is the circles area?

dolphi86 [110]

Answer:

113.04 cm

Step-by-step explanation:

We know the formula to find the area of a circle is

$A= pi(r^{2})$

And we are told to use 3.14 instead of pi so what we have now is,

$A=3.14(r^{2})$

We are also told the radius, r, is 6. So our equation now looks like this,

$A=3.14(6^{2})\\\\6^{2}$ is the same as 36, because 6x6 is 36.

Now we have,

$A=3.14(36)$

Which equals 113.04 and that is the area!

Hope that helps and have a great day!

Jerald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in s

vekshin1

104 = -16T2 + 729

16t^2 = 729 - 104 = 625

4t = +/-25

t = +/-6.25

Between 6.25 and 13.5 seconds after he jumps
