Answer:
Step-by-step explanation:
The equation to solve for "a" is:
The first step is to convert all of them to same bases.
9, 81, and 27, all can be expressed in base 3, lets do this:
We can use the property: to simplify further:
The right side has 2 same bases multiplied, we can simplify this using the property:
Thus, we have:
Now, both sides have same base, so exponents would be equal. Now lets equate and solve for "a":
So,
a = -4

Answer:
Height : 6
Step-by-step explanation:
volume of a rectangular prism is V=LWH
L is length and that is 20
W is width and that is 20
H is height and that is 6
The reason that L and W are 20 is because you would multiply those to get the base, and the base is already given, 400.
Since you know the volume is 2,400, a quick trick is that you divide 2,400/400. That equals 6.
So 20 x 20 x 6 = 2400
Area=1/2bh
50=1/2bh
times 2
100=bh
solve for b
divide by h
100/h=b
we hav to make a drawing
since it is isocoleese
h=b
100=b^2=h^2
h=b=10
answer is 10 inches
Step 1: 13+5x=30
step 2: subtract 13 from both sides; then youd get 5x=17
step 3: divide by 5
step 4: x=3.4
