Step-by-step explanation:
Answer:
153 cm²
Step-by-step explanation:
The area is given by the formula ...
A = (1/2)bh
where b is the base length, and h is the height measured perpendicular to the base.
The diagram shows b = QR = 18 cm, and h = 17 cm. So, the area is ...
A = (1/2)(18 cm)(17 cm)
A = 153 cm²
Answer:
(B) An uncontrolled experiment.
Step-by-step explanation:
In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled
Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the cholesterol level is decreased after particular time period,
Hence, it is an uncontrolled experiment.
Thus, option B is correct.
Answer:
Total time when cost are equal = 600 minutes
Total cost = 104
Step-by-step explanation:
Given:
Plan A = costs 8 plus an additional 0.16 for each minute
Plan B = costs 20 plus an additional 0.14 for each minute
Find:
Total time when cost are equal
Computation:
Assume total time = x minutes
Plan A = 8 + 0.16x
Plan B = 20 + 0.14x
Plan A = Plan B
8 + 0.16x = 20 + 0.14x
0.02x = 12
x = 600 minutes
Total time when cost are equal = 600 minutes
Total cost = 8 + 0.16x
Total cost = 8 + 0.16(600)
Total cost = 104
