We know that Santa's favorite snack used to cost $1.45 a box and the cost has gone up 15%. We must calculate the new price.

To calculate the new price we must calculate the 15% of the old price and then add up the old price and its 15%.

1. We must calculate the 15% of the old price

\text{ \$}1.45\cdot0.15=\text{ \$}0.2175

2. we must add up the old price and its 15%

\text{ \$}1.45+\text{ \$}0.2175=\text{ \$}1.6675

Finally, the price now is $1.6675

A car whose acceleration is constant reaches a speed of
Sergeu [11.5K]

Answer:

  12.5 s

Step-by-step explanation:

If acceleration is constant, speed is proportional to time. To increase the speed by 50 km/h, the car will need an additional time given by ...

  t/(50 km/h) = (20 s)/(80 km/h)

  t = (20 s)(50/80) . . . . . multiply by 50 km/h

  t = 12.5 s

It will take 12.5 more seconds for it to reach a speed of 130 km/h.

The distance from around the Earth along a given latitude can be found using the formula C=2∏r cos L , where r is the radius of
guajiro [1.7K]

Answer:

The distance reduces to 0 as you go from 0° to 90°

Step-by-step explanation:

The question requires you to find the distance using different values of L and check the trend of the values.

Given C=2×pi×r×cos L where L is the latitude  in ° and r is the radius in miles then;

Taking r=3960 and L=0° ,

C=2×\pi×3960×cos 0°

C=2×\pi×3960×1

C=7380\pi

Taking L=45° and r=3960 then;

C= 2×\pi×3960×cos 45°

C=5600.28\pi

Taking L=60° and r=3960 then;

C=2×\pi×3960×cos 60°

C=3960\pi

Taking L=90° and r=3960 then;

C=2×\pi×3960×cos 90°

C=2×\pi×3960×0

C=0

Conclusion

The values of the distance from around the Earth along a given latitude decreases with increase in the value of L when r is constant
