I=PRT
interest=I
P=principal
R=rate in decimal
t=time in years
P=1500
T=1
R=5%=0.05
I=1500 times 0.05 times 1
I=75
interst is 75
total amount is 1500+75=$1575 total
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
Answer:
616 ft²
Step-by-step explanation:
Since the floor of the tepee is circular, we find its area by using the area of a circle.
So, A = πr² where π = 22/7 and r = radius of circular floor = 14 feet
So, substituting the values of the variables into the equation, we have
A = πr²
A = 22/7 × (14 ft)²
A = 22/7 × 196 ft²
A = 22 × 28 ft²
A = 616 ft²
So, the area of the floor of the tepee is 616 ft²
Answer:
40 minutes
Step-by-step explanation:
Range = the highest value - the lowest value
= 45 mins - 5 mins = 40 mins
