Consider the figure shown below. Find the value of BL
Answer:
BL = 2
Step-by-step explanation:
Given:
AL = 3
AC = 10
BC = 9
AL = AM = 3 (tangents drawn form am external point)
CM = AC - AM
CM = 10 - 3
CM = 7
CM = CN = 7 (tangents drawn form am external point)
BN = BC - CN
BN = 9 - 7
BN = 2
BN = BL = 2 (tangents drawn form am external point).
BL = 2
A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment, 2 groups of people were created.Group I was placed in a quiet room where they went to sleep and they were timed on how long they slept. The group 2 was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke,their sleep times were monitored. What is the independent Variable ? And what is the Dependent Variable?
Answer:
independent variable- Presence or absence of soft jazz music
Dependent variable - sleep time
Step-by-step explanation:
The independent variable refers to that variable that is manipulated in an experiment. The independent variable is being studied and its effect on the dependent variable is documented. Presence or absence of soft jazz music is the independent variable.
The dependent variable is the response variable. It is that factor that changes when the independent variable is manipulated. In this case, the sleep time of the participants in the study is the dependent variable.

A student who is training for a distance race jogged for thirty minutes and covered a distance of 7.5 km. What is the average speed of the student?
Answer:
Average speed is 15km/hStep-by-step explanation:
Step one:
given data:
total distance =7.5km
time taken= 30 min= 0.5 hours
we know that the average speed is the average distance divided by time taken
Step two:
mathematically expressed as
speed=distance/time
substituting we have
speed=7.5/0.5
speed=15km/hour
Hence the average speed is 15km/h

Answer:
x = 12 or 12:204
Step-by-step explanation:
You have to set it up like this....
Just cross multiply.
[tex]\frac{3}{51}*\frac{x}{204}[/tex]
You'll multiply
3*204 = 612
51*x = 51x
612 = 51x (divide by 51 on both sides)
12 = x
12:204

Which is a linear graph, and which is a nonlinear graph?
How do you know?
Orange is linear; blue is nonlinear
Blue is linear; orange is nonlinear
Both are linear
Both are nonlinear
Answer:
Blue is linear
Step-by-step explanation:
For lines to be linear on a graph, they have to follow these 2 rules:
-be a straight line
-be written in the form of y=mx+b
Therefore, blue is linear and orange is nonlinear
what the slope of(-4,4) (-9,6)
Answer:
-2/5
Step-by-step explanation:
1. 4-6 = -2
2. -4- -9 = 5
3. -2/5
Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
slope formula is:
[tex]y2-y1/x2-x1[/tex]
so we plug in the coordinates
[tex](6-4)/(-9--4)[/tex]
which is
[tex]2/-5[/tex]
so the slope is
[tex]-\frac{2}{5}[/tex]

6k ÷ 7 = -3
Solve for k
Answer:
k = -3.5
Step-by-step explanation:
6k ÷ 7 = -3
Multiply 7 to both sides
6k = -21
Divide both sides by 6
6k/6 = -21/6
k = -3.5
To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.
6(-3.5) ÷ 7 = -3
-21 ÷ 7 = -3
-3 = -3
-3 equals -3 so it is correct that k = -3.5
