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...

Answer:
(9/10)/(2/5) = ratio of work times
2 1/4 times as long
Step-by-step explanation:
<u>Given</u>:
2/5 hours work in the morning
9/10 hours work in the afternoon
<u>Find</u>:
an equation for how many times as long was afternoon work compared to morning work
the equation solution
<u>Solution</u>:
a/m = r . . . . ratio of afternoon work to morning work
(9/10)/(2/5) = r . . . equation
(9/10)/(4/10) = r
9/4 = r = 2 1/4 . . . solution
The builder worked 2 1/4 times as long in the afternoon as in the morning.
Answer:
390 m (perpendicular to river) x 780 m (parallel to river)
Step-by-step explanation:
Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.
The total area and length of fence required are given by:
Rewriting the length of fence as a function of only x:
The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:
If x = 390 m, then:
The dimensions that will use the least amount of fencing are 390 m x 780 m
