Answer:
v = 47
Step-by-step explanation:
v = u + at
Plug in the values.
v = (12) + (5)(7)
Multiply 5 and 7.
v = 12 + 35
Add
v = 47
Hope this helps!
Answer:
1) The dependent variable is;
The recorded exam scores of the student
2) The independent variable items in the experiment are;
a) The method of study;
i) Through visual information only
ii) Using auditory information only
iii) Not studying at all
b) The duration of study
Four days
c) The number of questions in the exam
100-questions
Step-by-step explanation:
Dependent Variable
The dependent variable is the measured result of the experiment which are the values that change due to a change in the treatment applied in the experiment
The dependent variable is the output of the function of the experiment from an varied inputs to the experiment which is the independent variable
Independent Variable
The independent variable are the variable taken as the cause of the desired effect which is observed measured as the dependent variable
Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540
120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
x = 100
answer
B) 100
Answer:
comic books = 2
magazines = 15
Step-by-step explanation:
Let c = number of comic books bought
Let m = number of magazines bought
He bought 17 items, so
c + m = 17
Comic books cost $4 each and magazines cost $3 each.
He spent $53 on comic books and magazines, so
4c + 3m = 53
Rearrange c + m = 17 to make m the subject:
m = 17 - c
Substitute m = 17 - c into 4c + 3m = 53 and solve for c:
4c + 3(17 - c) = 53
⇒ 4c + 51 - 3c = 53
⇒ c = 2
Substitute c = 2 into m = 17 - c to and solve for m:
m = 17 - 2 = 15
