Answer:
10/27
Step-by-step explanation:
3^x = 10
We want to find 3^(x-3)
Rewriting
We know that a^(b-c) = a^b * a^ (-c)
3^x * (3^-3)
We know that 3^-3 = 1/3^3
3^x * 1/27
10 * 1/27
10/27
Given:
The ratio of the area between a small square of land and a large square
of land is 3: 7.
Total area of the two squares of land (in sq. meter) is 4000.
Required:
The area of each square of land.
Answer:
We have the ratio of the area between a small square of land and a large square of land is 3: 7.
Let

be the area of the square of land.
Then their ratio is given by,

Also given that the total area of the two squares of land (in sq.meter) is
4,000.
The area of
Therefore,

Therefore,the area of small square (in sq. meter) is,

and the area of large square (in sq. meter) is,

Final Answer:
The area of small and large square respectively (in sq. meter) is,1200 and 2800.
Oh my goodness . . .
What do you get when you multiply a number by itself ?
Do you get the square of the number ?
And what do you get when you square the square root of a number ?
Is it the number inside the square root ?
For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
√Q times √Q .
Isn't that just ' Q ' ?
And is this enough help ?
Answer:
Radius is 13
Circumference = 26π
Area is 169π
Step-by-step explanation:
use the radius, circumference, and area formulas.
Radius is 13
Circumference = 26π
Area is 169π
substitute pi for 3.14, 3, etc if needed
