Answer:
Difference = 250 students
Step-by-step explanation:
Let the total number of students be x.
Given the following data;
% driving = 30%
% riding = 60%
% walking = 10%
Number of students driving = 375
First of all, we would determine the total number of students.
Total = 30/100 * x = 375
0.3x = 375
Total, x = 375/0.3
Total, x = 1250 students.
Next, we determine the number of students walking;
Walking = 10/100 * 1250
Walking = 12500/100
Walking = 125 students
Finally, we would determine many more students drive to school than walk to school;
Difference = 375 - 125
Difference = 250 students
Answer:
- The length of VW = 36 units.
Step-by-step explanation:
We know that a rhombus is a quadrilateral with four sides. All four sides have the same length.
From the diagram, it is clear that
As all the four sides of the rhombus have equal length.
So we can observe
Add 12 to both sides
Divide both sides by 2
so
The length of VW= 6m-12
= 6(8)-12 ∵
= 48-12
= 36
Thereofore, the length of VW = 36 units.
Answer:
D. (-1, 0) and (0, -6)
Step-by-step explanation:
The system of equations:
y = -6x - 6
y = x² - 5x - 6
We equate the two equations;
-6x - 6 = x² - 5x - 6
x² + x + 0 = 0
x² + x = 0
x(x + 1) = 0
So, x = 0 or -1
When x = 0,
Then y = -6(0) - 6 = -6
When x = -1,
Then y = -6(-1) - 6 = 6 - 6 = 0
So the answer is: (0, -6) and (-1, 0)
Answer: No it is not a right triangle. It is an obtuse scalene triangle.
When we draw with replacement we have independent events and the probability of the conjunction is the product of the individual probabilities.
P(Green first & Blue second) = P(Green first) P(Blue second) = P(Green) P(Blue)
P(Blue) = P(Green first & Blue second) / P(Green) = (2/25)/(1/5) = 2/5
So 2/5 of the marbles are blue, (2/5)(15)=6 marbles
