Answer:

8 1/3% chance (1/12)

Step-by-step explanation:

There are 24 possible rolls (4 shapes * 6 numbers). The heart has 6 numbers, so we are already at 25% chance of getting a heart. Here, it's asking for 4 or 6, so since that's 1/3 of the numbers, multiply 1/3 by 1/4 for 1/12 or 8 1/3% chance.

Simplify expression 2/3[3f+12]+f

neonofarm [45]

Answer:

= 3f + 8

Step-by-step explanation:

Given that:

= 2/3[3f+12]+f

By simplifying:

2/3 will be multiplied inside the bracket as follows:

= 2/3*3f + 2/3*12 + f

By cancelling the terms with each other we get:

= 2f + 24/3 + f

By simplifying the fraction we get:

= 2f + 8 + f

Adding like terms

= 3f + 8

This is the simplified expression.

i hope it will help you!

A weather balloon is descending from the atmosphere. Its altitude changes by

OlgaM077 [116]

The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:

Amount of time x change per second = total change
135 x (-6) = X
-810 = X

Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.
