Answer:
SQUARE= 108 blocks
CIRCLE= 97.97
# OF BUNDLES= 2.05, 3
Step-by-step explanation:
square- find perimeter
- 22.5 x 4= 90ft
- 90ft/10inches
- convert 90 ft to inches> 90 x 12= 1080/10= 108
circle-
- find the circumference= c=2piR
- 2x3.14x13=81.64
- 81.64ft to in = 979.68/10
- =97 rounded
number of bundles = 205/100 =2.05, so 3
Answer:
42x + 14
Step-by-step explanation:
to solve this type of question , all you have to do is to follow some simple rule of BODMAS
B.............. bracket open
O.............. of
D................ division
M.................multiplication
A................... Addition
S........................... Subtraction.
so we are just going to apply the B
7 (6x + 2)
42x + 14
Answer:
Step-by-step explanation:
1) For each situation to grow or decay by a constant percent rate, it must be exponential. Therefore, the correct examples are
A. The number of cars sold doubles every year. It is a 200% growth every year.
D. Each time you start a car engine the remaining engine life decreases by 0.0075%. A case of decay
E. The number of people creating cat videos increases by 15% percent every year.
F. Computer technology increases by a factor of 3 every five years.
2) this is a case of exponential decay. The expression for exponential decay is
y = b(1 - r)^t
y = final value
b = initial value
r = decay rate
t = time
Given that
r = 10% = 10/100 = 0.1
b = 50 kilograms
y = W kilograms
The relationship is
W = 50(1 - 0.1)^t
W = 50(0.9)^t
