27 to the power of 3x=81

Mathematics
1 answer:
hoa [83]3 years ago
8 0

Answer:

x=4/9

Step-by-step explanation:

27 ^(3x) = 81

Replace 27 with 3^3    and 81 with 3^4

3^3^(3x) = 3^4

We know that a^b^c = a^(b*c)

3^(9x) = 3^4

Since the bases are the same, the exponents are the same

9x =4

Divide each side by 9

9x/9 = 4/9

x = 4/9

Can someone help? I know the volume can someone help with the surface area?
TEA [102]
To find the surface area you will find the area of each flat surface or each face.


The faces are in the shape of a rectangle , so multiply the length by the width.

A = lw
Front/ Back-3 1/2 x 3 1/3 = 11 2/3 ft.²

Sides- 3 1/3 x 3 1/3 = 11 1/9 ft.²

Top/bottom - 3 1/2 x 3 1/3= 11 2/3 ft.²

Add together to get the total surface area.

11 1/9+11 1/9+11 2/3+11 2/3+11 2/3+11 2/3 = 68 8/9 ft.²

The total surface area is 68 8/9 ft.².

Lisa has 3 quarts of milk. Sanjay has 12 pints of milk. Who has more?
Ira Lisetskai [31]

Sanjay, because quarts are twice as big as pints.

Step-by-step explanation:

Given

Milk quantity for Lisa = 3 quarts

Milk quantity for Sanjay = 12 pints

We have to convert both quantities in same unit so that we can compare both quantities.

We know that there are two pints in a quart.

So,

Lisa will have:

3*2 = 6 pints of milk

Hence,

Sanjay, because quarts are twice as big as pints.

Answer:

x = 15

Step-by-step explanation:

These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
