Answer:
The speed of the jet is 347 mph and the speed of the wind is 18 mph.
Step-by-step explanation:
We have the following:
x = the speed of the jet in still air.
y = the speed of the wind
we know that the speed is equal to:
v = d / t
therefore the distance would be:
d = v * t
if we replace with the information of the exercise we have:
3 * (x + y) = 1095
3 * (x - y) = 987
we must solve this system of equations, add both equations and we are left:
3 * x + 3 * y = 1095
3 * x - 3 * y = 987
3 * x + 3 * y + 3 * x - 3 * y = 1095 + 987
6 * x = 2082
x = 2082/6 = 347
now to calculate y, we replace:
3 * (347 + y) = 1095
1041 + 3 * y = 1095
3 * y = 1095 - 1041
y = 54/3 = 18
The speed of the jet is 347 mph and the speed of the wind is 18 mph.
Assuming that the figure is implying that angles 1 and 2 are the same, we have
So, the measure of angles 1 is
Answer:
True
Step-by-step explanation:
In order to calculate this, we simply need to replace the variable c with the value of -8 and solve the inequality.
-9c >= 63
-9 * -8 >= 63
72 >= 63
Since both values are negative the product will be positive. This product is 72 which is in fact greater than 63, thus making the statement True
