Answer:
7 4/5
5 1/2
17 13/55
Step-by-step explanation:
Answer:
a= 6
b = 7
c = 8
d = 7
e = 6
Step-by-step explanation:
Notice that the bike is 6 feet above the ground to start with, so when it starts rolling, the green dot is exactly 6 feet from the ground, which gives a=6
when the distance covered by the bike is 
, (see first red dot in the attached image), the position of the green dot is exactly 1 foot added to 6 ft= 7 feet
so b = 7
when the distance covered is 
, now the green dot would be at the top of the wheel (second red dot in the attached image) which involves adding 2 feet to the original 6 feet. That is: c = 8
when the distance covered is 
, the green dot is at the position of the third red dot in the attached image., that it exactly one foot added to 6 feet = 7 ft which gives the value of d = 7
and finally, when the distance covered is 
. the green dot has completed a full circle and is now again in its lower position (nothing - zero) added to 6 feet = 6ft, giving e = 6.

Answer:
y = -8/5
Step-by-step explanation:
Step 1: Write equation
5/8y = -1
Step 2: Solve for <em>y</em>
- Divide both sides by 5/8: y = -8/5
Step 3: Check
<em>Plug in y to verify it's a solution.</em>
- Substitute: 5/8(-8/5) = -1
- Multiply: -40/40 = -1
- Divide: -1 = -1
Based on the information given, it can be noted that the problem with the research is the problem of validity.
<h3>
Problems with validity.</h3>
It should be noted that in a research, a problem with validity takes place when there's a lack of reliability of the independent variable.
Also, it is a result of lack of representativeness of the independent variable and a lack of impact of the independent variable.
In this case, the researcher sets out to measure drug use on US college campuses by asking a representative sample of undergraduates whether they are currently receiving federal grants or loans. It should be noted that the question asked doesn't relate to the research.
In conclusion, there's a problem with validity.
