.95 to calculate, just divide 19 by 20
In an inverse proportion two veriables are inversely proportional to each other.You can write the equation as P=n/x, and N is the constant of proportionality.In the equation the X increases and the P decreases.
simplify : the exact value of sin 240
Explanation: sin(240)=sin(60+180)=-sin60
Final answer: the required vaalue of the sin 240 is -0.87
Answer:
16.86 ft/s
Step-by-step explanation:
Given that
Speed of the carousel, s = 14 rpm
Distance from the carousel, d = 23 ft
To start with, we convert the given speed to revolution per second, so that
s = 14/60 rev/sec
To find the needed speed, we use the formula
v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD
v = πnD, and we use this to find our needed velocity
v = 3.142 * 14/60 * 23
v = 72.266 * 14/60
v = 16.86 ft/s
Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it
Answer:
17 is the length of the hypotenuse.
Step-by-step explanation:
The pythagora theorem tells us a²+b²=c², where C is hypotenuse.
Replace the given info into the formula:
8² + x² = (x+2)²
64 + x² = x² + 4x + 4
64 - 4 = 4x
60 = 4x
x = 60/4
x = 15
Hypotenuse length is 15+2=17
