Answer:
Hey! I think I can help.
Parallel lines are lines that can't meet.Perpendicular lines are lines that can meet.
e.)Since the line at 12 and the line at 9 meets then it is a perpendicular line.
c.)Perpendicular line.
a.)Perpendicular line.
b.)Parallel line.
d.)Depending on how they are faced if the ends of the telephone wire meets the second one then it is perpendicular but if not then it is parallel that's if they are in different directions which they can not meet.Thank you for the question
Answer:
$5,000
Step-by-step explanation:
First, you have to determine the total amount of money she needs to save to cover the cost of the tuition by subtracting the financial aid, the scholarship and the amount her parents plan to contribute from the total cost of the tuition:
40,000-(40,000/4)-(40,000*25%)-5,000
40,000-10,000-10,000-5,000
40,000-25,000= 15,000
She needs to save a total amount of 15,000. Then, you need to divide this amount by 3:
15,000/3= $5,000
Julieta will need to save $5,000 each year over the next 3 years before her first year.
Answer:
{f, a}
Step-by-step explanation:
Given the sets:
X = {d, c, f, a}
Y = {d, e, c}
Z ={e, c, b, f, g}
U = {a, b, c, d, e, f, g}
To obtain the set X n (X - Y)
We first obtain :
(X - Y) :
The elements in X that are not in Y
(X - Y) = {f, a}
X n (X - Y) :
X = {d, c, f, a} intersection
(X - Y) = {f, a}
X n (X - Y) = elements in X and (X - Y)
X n (X - Y) = {f, a}
Current trees = 25
trees when workers are finished = 80
Subtract the number of current trees (25) to the number of trees that are when the workers are finished:
80-25 = 55
The workers planted 55 trees today
