The area of a playing card is 48 square centimeters. It is 8 centimeters tall. How wide is it?
il63 [147K]

Answer:6

Step-by-step explanation:

Area of a rectangle = length × width

Length = 8

Breadth = ?

Area = 48

L × B = Area

8 × B = 48

Divide both sides by 8

B = 48 ÷ 8

B = 6

I really need help pleaseee
Dmitriy789 [7]

Answer:

P=163,487,500

Step-by-step explanation: P=Ae^(kt)

151000000=145000000*e^(k5)

151000000/14500000=e^(k5)

1.04137931=e^(k5)

Ln 1.04=Ln e^(k5)

0.04=k5

k= 0.008

P=145,000,000*e^(.008*15)

P=145,000,000*e^0.12

e=2.71828

P=145,000,000*1.12749685

p=163,487,500

A circle has a circumfernce of 13 it has a arc length of 11. What is the central angle of the arc in degrees
tatiyna

Answer: 304.6°

Step-by-step explanation:

First of all, using the circumference of the circle formula to find the radius of the circle.

Circumference of the circle = 13, ie

2πr = 13,

r = 13/2π ---------------------------- 1

Now getting the radius of the circle now, you now substitute for this in the formula for finding the length of an arc to get the central angle.

Arc length = 11 , ( 2πr0°/360) or (πr0°/180), so

πr0°/180 = 11 ------------------------ 2

Now solve for 0°, the central angle of the angle by making it the subject of the formula.

πr0° = 180 x 11

0° = 180 x 11

----------- ----------------- 3

πr

Now, put equation 1 in equation 3 and solve.

0° = 1980

--------

π x 13/2π

= 1980 x 2π

-----------

π.x. 13

= 1980 x 2

----------

13

= 3960/13

= 304.6°

Therefore, the central angle of the arc is 304.6°

Please be meticulous and understand the way I change the r in the denominator. It was the rule in fraction when dividing.
