Answer:
20
Step-by-step explanation:
<em>Refer to attached</em>
Imagine the rod cut and opened to make a rectangle with sides of 4 and 12
As the string goes 4 times, the length of the rod is divided by 4 parts of
We have triangle of sides 3 and 4, therefore the long side is 5
The length of the string is:
300times, because 6xs10^5 is equal to 600000 and 2xs10^3 is 2000, and if you divide you would get 300
Answer:
80 sets costing $25/set
120 sets costing $45/set
Step-by-step explanation:
let x = number of sets costing $25/set
let y = number of sets costing $45/set
we have to build eqautions form the info given
(1) . total sets = 200 x + y =200
(2) . total sets = 7400 25x + 45y = 7400
use the substitution method
(rest of work shown below in the picture)
Its D because its an negitive number
#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) =
(multiply both sides by 19 to isolate x)
19 sin(58°) = x (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) =
(multiply both sides by
)
(flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x
