Answer:
A dependent variable is a factor that changes because of procedures conducted on the independent variable
Step-by-step explanation:
Using a cause and effect analogy, the independent variable is the causal variable. The independent variable or variables are the variables on which what is being measured, has no effect, and it is the variable the investigator manipulates to find the effect on the dependent variable.
The dependent variable are the variables that shows he effect of the changes made and manipulations to the independent variable. The dependent variable is therefore, the effect variable
Therefore, the correct option is ' A dependent variable is a factor that changes because of procedures conducted on the independent variable'
Answer:
Therefore the game board is divided into 81 smaller squares.
Step-by-step explanation:
Given that, there is a square game.
Consider x be length of one side the square.
The volume of the square is = side ×side
=x² square units
Since the length of side of smaller square is one-ninth of the game board.
Then one side length of the smaller square is
units.
The area of a smaller square is 

Let a number of square is formed from the game board.
a ×The area of one smaller square= The area of game board.
According to the problem,



Therefore the game board is divided into 81 smaller squares.
Because .45 divided by 23 is .0195621739
That is how much it is per dollar
That answer times 72 is 1.408695652
So the size of the jar is about 1.41 oz
Answer:
Billy used 28 mins 30 sec to mow the lawn and Bobby used 43 mins 30 sec to now the lawn both within 72 mins
Step-by-step explanation:
let x represent Billy
let x+15 represent Bobby
x + x + 15 = 72
2x = 72 - 15
2x = 57
2x/2 = 57/2
x = 28.5 minutes = 28 minutes 30 seconds
Bobby = x + 15
= 28.5 + 15
= 43.5 minutes= 43 minutes 30 seconds
Answer:
17.2°
Explanations
To find angle A, use the cosine rule.
a^2 = b^2 + c^2 - 2 × a × c cos A
4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A
16 = 49+ 100 - 140 × cosA
16 = 149 - 140cosA
16- 149 = - 140cosA
-133 = - 140cosA
cosA = 133/140
cosA = 0.95
A = 17.2°
