8x = 3x + 15 ( minus 3x from both sides)
-3x -3x
5x = 15
Divide both sides by 5 to isolate the variable

There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, what is the Potential Energy that the wether vane has?
Answer:
Potential Energy = 8550 Joules
Step-by-step explanation:
The potential energy of the body is the energy possessed by it due to its position therefore:
Potential energy = mgh
m = mass of the body measured in kg
g= acceleration due to gravity
h= height or distance measured in meters
But in the question asked we are not given mass but weight so
w= mg measured in newtons
We have
w= 190 N
h= 45m
PE= mgh
PE = w h= 190 * 45 = 8550 J
The unit of energy is Joule.
6 boxes of 3-inch incense sticks for $22.75 is a better buy than 8 boxes for $30 and 10 boxes for $38.00
True
False
Answer:
Step-by-step explanation:
22.75/6 boxes is $3.79 per box
30/8 boxes is $3.75 a box
38/10 boxes is $3.80 a box
68/18=3.70 a box if you combine the last two.
So no, the 6 boxes at $3.79 a box is not a better buy.

Answer:
Part A: 5 miles per hour or 12 min per mile.
Part B: 30 min to get to his friends house.
Question 16 Part B: 30 minutes.
Step-by-step explanation:
Part A:
36 min for 3 miles so the unit is :
36/3 = 12 so: 1 mile per 12 min and 5 miles per hour.
Part B:
21/2 miles away so:
one mile per 12 min so 2.5 x 12 = he'll get there in 30 min.

A researcher wants to know if eating a mint affects whether people can distinguish between two popular orange juice brands. To conduct an experiment, the researcher places participants in two groups. The treatment group will eat a mint before drinking a juice, while the control group will not eat a mint before drinking. Then the participants will guess the juice brand.
Randomization is important when assigning the participants to the treatment and control groups to ensure
that there will be the same number of participants in both groups.
that the experiment results can be generalized to all people.
that both groups have participants that like both popular juice brands.
that both groups are roughly equivalent with regards to demographics and juice preferences.
Answer:
D
Step-by-step explanation:
Just took the quiz trust me
Randomization helps to eliminate the effect of sampling bias in an experiment. Therefore, random assignment of participants ensures equivalence in terms of the demographic and juice preference.
When subjects are randomly assigned to the groups, it eliminates the possible bias which may arise from personal preference which subjects have for a particular juice and which may yield a trend which isn't as a reflection of the actual study.
Therefore, the elimination of bias as a result of random assignment helps to strike a balance between the treatment and control samples regarding preference.
