A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 5 revolutions per minute. 1 minute = (1/60) hour.
= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14
= 600*3.14 = 1884 radians / hour
but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile
Linear velocity, v = ωr
v = 1884 radians / hour * (10/5280) mile
v ≈ 3.568 miles / hour
Answer:
x = 150°
Step-by-step explanation:
Start by cutting the shape into two triangles by bisecting the 30°
Now we have two triangles that have two angles 90° and 15°
Subtract 15° from 90°, you'll get 75°
Double 75° because x is split into 2
150° = x
Also, were given 3 angles, this is a quadrilateral.
90° + 90° + 30° = 210°
360° - 210° = 150°
Answer:
$700 Deposit account that earns 1.8% per year . what happened after 6 years??
1.8 x 6 = 10.8%
75.6
75.6 is 10.8% of 700
Step-by-step explanation:
What is 10.8% of 700?
Y is 10.8% of 700
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 10.8% * 700
Converting percent to decimal:
p = 10.8%/100 = 0.108
Y = 0.108 * 700
Y = 75.6
Answer:
17
Step-by-step explanation:
Substitute the value of the variable and simplify.
Anything raised to the power of 0 is one.
16 + 1 = 17
If Frank is planting <em>b</em> seeds in one and <em>5b + 10</em> in the other, the expression showing the total is b + (5b + 10), or 6b + 10 seeds.
