Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
All three of them are variable terms because they all contain a variable and a term would be the whole set of numbers that are separated by the addition signs. in this one the variable terms are 6x^2, 3xy, and 4z<span />
Answer: 30y - 25b +5
Step-by-step explanation:
(look at attachment image fir explanation)
One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x). Solve this equation for x. To do this, you might try multiplying both sides of this equation by x to eliminate fractions.
Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.
Yellow gumballs = 36
Total = 100
