Answer:
b = 7√3
Step-by-step explanation:
This 30°- 60°- 90° triangle has the proportions:
side opposite of the 30° angle = x
side opposite of the 60° angle = x√3
side opposite of the 90° angle = 2x
____________________________
Given the side opposite of the 30° angle which is 7 units long, this can be thought of as x. Knowing the proportions of the other sides, we can find b knowing that this is the side opposite of the 60° angle which is x√3.
Since x = 7, x√3 = 7√3, and therefore
b = 7√3.
Answer:
Step-by-step explanation:
I'm sure by now you have learned the difference between mass and weight. Mass will never change regardless of where something is while weight changes depending upon the pull of gravity. If we want the mass, then we have to take the weight on Earth and divide by its pull of gravity. The equation for that will be
W = mg where W is the weight in Newtons, m is mass and g is gravity.
685 = m(9.8) so
m = 7.0 × 10¹ kg
Now that we know that mass, and also because we know that the mass is constant no matter where the astronaut is, we can find his weight on Jupiter.
W = (7.0 × 10¹)(25.9) so
W = 1800 N
$4.84 is the correct answer
Answer:
516 students preferred pizza
Step-by-step explanation:
To solve this problem we have to calculate 60% of the total students (860)
To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60
860 %60 = 860 / 100 * 60
860 / 100 * 60 =
8.6 * 60 = 516
60% of 860 is 516
this means that for Friday lunches 516 students preferred pizza
