Right triangle PQR is shown on the graph below. If the point (x, 7) lies on the line that goes through side of the trianglethen what should be the value of x?
A. -2
B. 5
C. -3
D. 3
Answers
Answer:
C. -3
Step-by-step explanation:
First, find the slope of side QR. Calculate the slope by finding the ratio of the difference between the y-coordinates and the difference between the x-coordinates of points Q and R.
The slope of side QR can be found as shown below.
Now, using the slope of side QR, draw a triangle RST similar to the right triangle PQR with S(x, 7) as one vertex.
Next, find the value of x as shown below.
Therefore, the value of x in the point (x, 7) is -3.

Bernite is selling candy bars for a school fundraiser. The school paid $20.00 for a box of 15 king-size candy bars and Bernite sells then for $2.00 each. What is the relationship the amount of candy sold and the amount of money earned? (Multiple answer choice)
a. The relationship is linear
b. The relationship is non-linear
c. The relationship is proportional
d. The relationship always results in a positive profit.
e. The relationship always results in a negative profit
Answers
Answer:
e. The relationship always results in a negative profit
b. The relationship is non-linear
Step-by-step explanation:
From the question above it could be found that, the relationship always result in negative profit. This is because:
To the school purchase,
Selling price of Candy bars in a box = $20.00
On the other hand,
Each Candy bar cost = $2.00
No of Candy bars in a box = 15
Total cost = $2.00 x 15 = $30.00
Loss (negative profit) = Total cost - Selling price
= $30.00 - $20.00 = $10.00
This also shows that, the relationship is non-linear because there is no direct relationship between the selling price and the expected profit that was supposed to have been earned.

3+5=8. 360÷8=45. 45×3=135
If the ratio of cars to trucks in the parking lot is 3:5. If there are 360 vehicles in the parking lot, then there are 225 trucks
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
The ratio of cars to trucks in the parking lot is 3:5.
there are 360 vehicles in the parking lot
(360-x)/x=3/5
Cross Multiplication
5(360-x)=3x
1800-5x=3x
1800=8x

Ten students are chosen from a statistics class of 22 students. Let X be the number who got an "A" in the class. Is this a binomial distribution, and if so, what is the number of trials?
Answers
Answer:
Yes, this is a Binomial distribution, and the number of trials is 10.
Step-by-step explanation:
From the given information:
We are being told that ten students are chosen from a statistics class of 22 students.
If X represents the random variable for the number of students who got an "A" in the class.
Then we have two possible outcomes;
Number of students that got an "A" = (Success)
Number of students that did not get an "A" = (Failure)
Thus, this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much fatter did she run on Tuesday ?
Answers
Answer:
[tex]Difference = \frac{13}{40}[/tex]
Step-by-step explanation:
Given
[tex]Thursday = \frac{3}{8}\ mile[/tex]
[tex]Tuesday = \frac{7}{10}\ mile[/tex]
Required
How much farther is she on Tuesday
To do this, we simply calculate the difference between distance covered on both days.
[tex]Difference = Tuesday-Thursday[/tex]
[tex]Difference = \frac{7}{10} - \frac{3}{8}[/tex]
Take LCM
[tex]Difference = \frac{28- 15}{40}[/tex]
[tex]Difference = \frac{13}{40}[/tex]
Hence, she ran 13/40 mile farther on Tuesday
