Answer:
Descriptive research design
Step-by-step explanation:
Descriptive research design is a type of quantitative research design that tends to describe/depict the current status (condition) of a particular variable or phenomenon. In the case above, the research is quantitative because it deals with quantifiable data, which is the preference(quantity) of cosmetics. Savannah wanted to describe the preference of cosmetic use among adolescents, young adult, middle adult and the late adult women, which makes it a descriptive research design. It does not involve conducting experiment, or generating correlations etc.
Therefore, it is a Descriptive research design
We can assume that the point the ladder creates with the ground and building is a triangle. You can use the Pythagorean theorem to solve this.
A^2 + B^2 = C^2
The ladder is C, and the building can act as A or B, so for the purpose of this explanation, I’ll make it A.
11^2 + B^2 = 14^2
Figure out the squares
121 + B^2 = 196
Subtract 121 from both sides
B^2 = 75
Square root B^2 and 75
B = 5 root3
You could have -1(4n - 6)
1 steak costs $9.99
2 steaks cost 2*9.99 = $19.98
This is before tax is applied
Apply the 6% tax to get
6% of 19.98 = (6/100)*19.98 = 0.06*19.98 = 1.1988
which rounds to 1.20 (rounded to the nearest penny)
The sales tax is therefore $1.20
Add this to the previous total (19.98) and we get a grand total of 19.98+1.20 = 21.18 which is the final cost (with tax included)
note: we can multiply 19.98 by the value 1.06 to get 19.98*1.06 = 21.1788 and that rounds to 21.18; so it's a different route to the second answer
