log 25 = log 5^2 = 2log 5 = 2(0.6990) = 1.398
I assume that the question is missing log(5).
log(5) = 0.6990
We can factor out log(25) using 5.
log(25) = log(5^2)
Rewrite it using the power rule [ ]
log(5^2) = 2 log(5)
Simplify using the given values.
2(0.6990)
1.3980
Therefore, log(25) = 1.3980
Best of Luck!

Answer:
The time required by 9 people to paint 7 walls is 49 minutes
Step-by-step explanation:
Given as :
The number of people (p1) = 7
The work done by them (w1) = 4
The time taken (T1) = 36 minutes
Again :
The number of people (p2) = 9
The work done by them (w2) = 7
Let the time Time taken (T2) = T2
So, we know as :
= Constant
SO, =
Or, =
Or, =
Or , = T2
∴ T2 = 49 minutes
Hence The time required by 9 people to paint 7 walls is 49 minutesAnswer

By using the principles of inverse variation, it is determined that it would take 20 workers 38 days to build a similar house.
Explanation:
The problem is an example of inverse variation, where the amount of time (days) to build a house decreases if the number of workers increases. In this specific scenario, one house was built in 76 days by 10 workers. We can represent the inverse variation relationship with the equation: days * workers = constant.
Using the given data, the constant can be calculated by multiplying the days by the number of workers, hence:
constant = 76 days * 10 workers = 760
To find the number of days it would take for 20 workers to build the house, we divide the constant by the number of workers:
days = constant / workers = 760 / 20 = 38 days
This means that it would take 20 workers 38 days to build a similar house.

The least amount of acute angles would have to be 2 because if you had 1, the others would have to be acute, otherwise the triangle would not form properly.

If you draw a diagonal through the square then you get two right triangles. So the area relation between a square and a right triangle is going to be half. The area of the triangle is half the area of the square.
Also the formula for area of a square is length times width.
And the formula for the area of a right triangle is 0.5 times length times width.
So if you set up the equation (let's use * as multiplication symbol ):
Area of a Square : Area of a Right Triangle
length * width : 0.5 * length * width
(Divide by length * width on both sides)
1:0.5 or 2:1
