Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
Answer:
1. 8 + 13 = 13 + 8.
2. 6 + ( 12 + 4) = 6 + ( 4 + 12).
Step-by-step explanation:
Answer:

Step-by-step explanation:
we have a exponential function of the form

where
y is the population of bacteria
a is the initial value
r is the rate of growth
x is the number of hours
we have
a=3,000 bacteria

For x=2, y=3,300
substitute


Apply square root both sides




substitute in the equation


<u><em>Predict how many bacteria will be present after 16 hours</em></u>
For x=16 hours
substitute


It would $17.47. if you times $4.99 by 3.5 pounds of cherries then your answer will be $17.47
La formula para calcular cualquier descuento esta dada por (100 - descuento)/100
en ese caso seria Y = (1-0.3)X = 0.7X
