When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>
Answer:
x = 23.78
Step-by-step explanation:
From the information given, we can construct the triangle shown in the attached picture.
With respect to the angle 18, we have the hypotenuse (25) and we want to know the adjacent side (x). Thus, what trigonometric ratio relates adjacent to hypotenuse? COSINE! Thus we can set-up the ratio shown below and compute x.

Answer:
3. 24
4. 10 1/2
Step-by-step explanation:
Answer:
y=6x+8
Step-by-step explanation:
All of the other equations are raised to the power of two, which forms the graph into a parabola, and this changes the rate of change.
