Answer:

height is 5 units

Step-by-step explanation:

We are required to determine the height of a triangle that has an area of 30 square units and a base measuring 12 units.

The formula for the area of a triangle is given as;

Area=\frac{1}{2}*base*height

We plug in the given values and solve for the height;

30=\frac{1}{2}*12*height\\\\30=6*height\\height=5

A standard die is rolled three times. What is the probability of rolling a number less than 5 on all three rolls?
katrin [286]

Answer:

5/6

Step-by-step explanation:

This is because when you roll three times, there are 18 possible numbers (six numbers three times). If you want to get less than five each time, that is 5 number x 3 rolls = 15 numbers.

So...You get 15/18 which simplifies to 5/6

2 − 10n = 2 + 4n<br> What does n equal?
tiny-mole [99]

Answer:

0 =n

Step-by-step explanation:

2 − 10n = 2 + 4n

Add 10n to each side

2 − 10n+10n = 2 + 4n+ 10n

2 = 2 + 16n

Subtract 2 from each side

2-2 = 2+16n-2

0 = 16n

Divide each side by 16

0/16 = 16n/16

0 =n
