Answer:
30
Explanation:
the formula for calculating the area of a right-angled triangle is ½ × base × height, where the base of the triangle is one of its sides, and the height of the triangle is a line connecting the opposite vertex (corner) of the triangle to the base at a right angle.
in this case, because the triangle is already a right-angled one, we do not have to draw a hypothetical line to serve as the height.
all we have to do is apply the formula using the numbers given in the diagram to represent the base and the height.
½ × base × height = ½ × 12 × 5 = 30
i hope this helps! :D
Answer:
1 in 18
Step-by-step explanation:
The highest possible number Hillary can get is 12, meaning that the only odd number above 10 which she can get is 11.
There are two possible ways in which Hillary can get 11:
(a) Hillary rolls a 5 on her first cube and a 6 on her second cube
(b) Hillary rolls a 6 on her first cube and a 5 on her second cube
There are 34 other possible outcomes which Hillary can have when rolling her number cubes, for a total of 36 possible outcomes.
Since 2 of these outcomes result in a roll of 11, Hillary has a 2 in 36 chance of rolling an 11, which can be simplified as 1 in 18.
Answer:
Step-by-step explanation:
Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula
Here's what we have:
The amount after a certain time that she has in the bank is 4672.12; that's A(t).
The interest rate in decimal form is .18; that's r.
The number of times the interest compounds is 12; that's n
and the time that the money is invested is 3.5 years; that's t.
Filling all that into the formula:
Simplifying it down a bit:
Raise 1.015 to the 42nd power to get
4672.12 = P(1.868847115) and divide to get P alone:
P = 2500.00
She invested $2500.00 initially.
From what is there it is nearly impossible to find an exact number so I would say C... hope this helps
To find the gold per cubic meter you have to divide the amount of gold by the size of the area. So you would do .78/1.5 which would give you .52g/m3
