Answer:

Greater than 3

Step-by-step explanation:

Logarithms explain the relationship between exponents.

Think of them as such, except they got their bases and exponents switched.

In this logarithm:

$log2(10)$

basically says 2 to the power of <em>what</em> gets you to 10.

Now let's experiment: 2^2=4, 2^3=8. 2^4=16.

Wait, we already crossed 10. Now we know that log2(10) must be in between 3 and 4. We don't need to find the exact value, because thats not what the question asked.

It's between 3 and 4, so it has to be greater than 3 but less than 4. Thee is your answer!

Have a nice day! :)

family has a square driveway with an area of 210.25 m exponent 2. Find the perimeter of the driveway. Round your answer to the n

miv72 [106K]

Answer:

191 ft.

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) of square = 210.25 m²

Perimeter (P) =?

Next, we shall determine the length of each side of the drive way. This can be obtained as follow:

Area (A) of square = 210.25 m²

Length (L) =?

Area of a square is given by:

A = L²

210.25 = L²

Take the square root of both side

L = √210.25

L = 14.5 m

Thus, the length of each side of the drive way 14.5 m

Next, we shall determine the perimeter of the drive way. This can be obtained as follow:

Length (L) = 14.5 m

Perimeter (P) of square =?

Perimeter of a square is given by:

P = 4L

P = 4 × 14.5

P = 58 m

Finally, we shall convert 58 m to foot. This can be obtained as follow:

1 m = 3.3 ft

Therefore,

58 m = 58 m × 3.3 ft / 1 m

58 m = 191.4 ft

58 m = 191 ft

Thus, 58 m is equivalent to 191 ft.

Therefore, the perimeter of the drive way is 191 ft.

How do you round 3.99 to the nearest tenths?

Lemur [1.5K]

3.99 = > 3 + 0.99

first let's round up the 0.99, and the 9 rounds up to 1.0 so 0 + 1.0 = 1.

3 + 1 = 4, rounded up.

to the nearest tentth, 4.0.

the .0 simply means 0 tenths, since it's a whole 4.
