Answer:
2.8miles
Step-by-step explanation:
Miles = 7
Time= 60min
constant(k) = 7/60
~~~~~~~
miles = x
time= 24 min
7/60 = x/ 24
x= 7/60 x 24
= 2.8 miles
iI hope im right!!
Answer:
Number of independent variables = 2
Step-by-step explanation:
Lets stary with definitions. First of all, variables are properties, of an experiment that take on different amounts or values, rather than a constant that has one unchanging value assigned to it.
Now, we have two kinds of variables namely dependent and independent variables. For this question, we need to know independent variables. Independent variables are variables that could be manipulated at discretion. In the question, the independent variable is "the size of breakfast" because the experimenter chose by reason of choice to either use 350-calories or 750- calories breakfast.
However, the dependent variables are those whose outcomes are with respect to the change in the independent variable. The experiment is actually out to observe how the dependent variable plays out during the experiment. In our example, the dependent variable is "overall food consumption throughout the rest of the day". Thus, the outcome of the overall food consumption throughout the rest of the day is as a result of the size of breakfast taken.
Now, the independent variable can take on various levels, and the number of levels are the number of experimental conditions that the independent variables can take. In our example the independent variable (size of breakfast), was either 350-calories breakfast or 750-calories breakfast, hence it took 2 experimental conditions.
Thus, we say that number of independent variables is 2.
Answer:
The measure of 
.
Step-by-step explanation:
Given,
AB║CD and
m∠2 = 60°
Solution,
Since, in the figure given in attachment line segment AB is parallel to line segment CD. And t is the transversal line.
The theorem of parallel lines states that,
"If two lines are parallel and cut by a transversal line then the pair of corresponding angles are congruent."
So according to the theorem of parallel lines,∠2 and ∠6 makes a pair of corresponding angle.
And the measure of corresponding angle is equal.
So, m∠2 = m∠6
Thus the measure of .

Answer:
Betsy will save $121 in 5 weeks.
Step-by-step explanation:
We can see that Betsy's savings are 3 times the saving of her last week. We can see that this is an geometric sequence as 1,3,9,..
To find the sum of our geometric sequence we will use 
, where n is number of terms we are taking sum of, a is first term of sequence and r is common ratio of the sequence.
Therefore, Betsy will save $121 in 5 weeks.
