skskhfkakakan what is this haha
Total cost of painting 225 cm² will be:
Cost=(total area)×(cost per cm²)
area=225 cm²
cost per cm²=$0.12
thus the total cost will be:
Cost=0.12×225=$27
Answer: $27
Answer:
a) 376.66
b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) 377
d) 40.77%
Step-by-step explanation:
a) 37% of 1018 is;
37/100 × 1018 = 376.66
b) Thus, the result in a above is not a whole number. Thus;
No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) from a above a, we got a value of 376.66.
Now the actual number would be preferably an integer. Thus, actual number is approximately 377.
d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%
Answer:
a) x = 54/tan(theta)
b) theta = arctan(54/x)
Step-by-step explanation:
a) The tangent ratio is the ratio of the side opposite an acute angle in a right triangle to the adjacent side. For the angle of elevation, the adjacent side is the distance x to the flagpole. The side opposite is the 54-foot difference between the top of the man's head and the top of the flagpole. So, we have ...
tan(theta) = 54/x
Solving for x gives ...
x = 54/tan(theta)
__
b) Solving the first equation in the previous part for theta involves the inverse tangent function:
theta = arctan(54/x)
