Answer:
n = 12.5t
Step-by-step explanation:
add up the calories burned in both days
275 + 450 = 725
add up the minutes running on both days
22 + 36 = 58
divide calories by minutes
725 calories/58 minutes = 12.5 calories/1 minute
So 12.5 multiplied by any number of minutes tells you how many calories you burned
The number of calories you burned is dependent on the number of minutes you ran.
Step-by-step explanation:
CB is the Hypotenuse of the right-angled triangle CDB.
Pythagoras :
CB² = 20² + 21² = 400 + 441 = 841
CB = sqrt(841) = 29
=> radius = 29/2 = 14.5
the total circumference of the circle (360 degrees) is
2×pi×r = 29×pi
but here we need only the part of the circumference for 180-70= 110 degrees.
CD arc = 29×pi × 110 / 360 = 29×pi×11/36 =
= 27.83800157 ≈ 27.84 cm
The answer would be Angle 1 is equal to angle 3 by the subtraction property of equality.
Answer: The manager should sell the chair for $1740.
Step-by-step explanation:
45% of 1200 Solve this to find the amount increase
0.45 * 1200 = 540 Now add this amount to find the price.
$1200 + $540 = $1740
or you could do it this way
100% + 45% = 145%
145% of 1200 =?
1.45 * 1200 = 1740
