Answer:
284.625
Step-by-step explanation:
Arrange the numbers highest to lowest.
Find the middle value in the arrangement.
When you see a "%" you need to ask " a percent of what"?
Here, it's a percent of the original prize, so the discount is 20% of the original prize, that is 20% of 35.
20% is also 20/100 or 1/5, so we can calculate this like this:
so the discount is 7 dollars.
Answer:
A. 600
B. 565.2
C. 8000
D. 8125.376
Step-by-step explanation:
Rounding up from 500 is 600 (Nearest HUNDRED)
Rounded up from 565.234 is 565.2 (NEAREST TENTH)
Rounded down from 8125.3758 is 8000 (NEAREST THOUGHAND)
Rounded up from 8125.3758 is 8125.376 (NEAREST THOUSANDTH)
Answer:
Option D
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:
b^2 = a^2 + c^2 - 2*a*c*cos(B).
The question specifies that a=42, B=120°, and c=35. Plugging in the values:
b^2 = 42^2 + 35^2 - 2(42)(35)*cos(120°).
Simplifying gives:
b^2 = 4459.
Taking square root on the both sides gives b = 66.78 (rounded to the two decimal places).
This means that the length of the third side is 66.78 units!!!
You- y=50+20x
friend y=30+20x
If you subtract, the difference is only 20 dollars at any given months since the rates are the same
