Answer:
The answer to your question is It will take 1 hour to find Marissa
Step-by-step explanation:
Data
Marissa time = 7:00 am speed = 12 mi/h
Roommate time = 7:30 am speed = 18 mi/h
Process
1.- Calculate the distance traveled by Marissa in 30 min (0.5 h)
d = vt
d = (12)(0.5)
d = 6 mi
2.- Write an equation to solve this problem
Distance traveled by Marissa = Distance traveled by the roommate
6 + vmt = vrt
- Substitution
6 + 12t = 18t
- Solve for t
6 = 18t - 12t
6 = 6t
t = 6/6
t = 1 h
P v Q is a disjunction, which is true whenever P or Q is true or both are true. P v Q is false only when P and Q are both false.
You know that Q is false, because 3 is not the square root of 10, so the only possibility for P v Q be true is that P is true.
If that is the case, you have this relation:
T F ---> T
which means True and False imply True
Answer:
Step-by-step explanation:
True statements
All equallateral triangles are similar. Their sides are all in the same ratio when comparred.
All squares are similar. Same reason as equilateral triangles. All sides to both squares compared are the same.
False Statements
Isosceles triangles can and usually do have different base angles.
rectangles can have all sorts or side lengths. The only requirement is consecutive sides form right angles.
2 rhombuses can have side lengths that are in the same ratio, but the heights are not in the same ratio. That eleminates.
Answer
These are the only true ones: Statements 2 and 5 are true. The rest are not.
Answer:
210 degrees
Step-by-step explanation:
Convert the problem from radians to degrees using the ratio 180/ and it will give you 210.
3 times a year for 2 years is equal to 3 x 2, or 6. So we know that she will have to pay her bill 6 times.
The cost for each trimester is $1450, but we still have to add the book costs ($350). So, 1450 + 350 = 1800.
Now we know that she has to pay $1800 six times. So the equation will be:
1800 x 6 = 10800.
It will cost Samantha $10,800 to get her degree.
