The side with the larger spaces units are the inches and the side with the smaller spaced units are the centimeters
Your first line calculation is already true but reversed. The demand will decrease (that mean the formula would be minus) by 20 gallons for every $0.4 price increase, which means 50 gallons/$. To find the formula you need to insert one sample of either the first equation (65gallon and $3.1) or 2nd equation (45 gallons and $3.5). The formula for demand should be:
q= C - 50p
65 gallon= C- 3.1 * 50
C= 65 gallon + 155 gallon= 220 gallon
The formula would be:
q= 220- 50p
So the second question can be solved by putting 0 on the Q. It would be:
q= 220- 50p
0=220-50p
50p=220
p= $4.4
OK you must establish a relation of the two first quantities, it means 1/4 lime : 3/4 oil, then with 1 cup oil it will be x quantity of lime
1/4 cup lime____3/4 cup oil
x_________1 cup oil x = 1*1/4÷3/4 , x= 1/3 lime juice
Answer:
x = 2.24
Step-by-step explanation:
I will ASSUME that the 15 represents the angle in degrees
We can make a similar triangle by adding the purple lines as shown.
Any triangle inscribed in a circle with one side as a diameter is a right triangle.
We know it is similar triangle because it shares two common angles, the right angle and the 75° angle at the far right. Then
z = 2Rsin15 = 2(16.7)sin15
x = zsin15 = 2(16.7)sin²15 = 2.237375756799...
