This is exponential growth/decay type problem...
F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case I=1250 and r=(1-.045)=0.955 so
F=1250(.955)^t and we want to find t for when F=800
800=1250(.955)^t
.64=.955^t take the natural log of both sides...
ln.64=t ln.955
t=(ln.64)/ln.995
t≈9.69 weeks
t≈9.69 weeks (to nearest hundredth of a week)
A box with a square base and a top is to be constructed from 10 square meters of material. 40 square meters will maximize the volume that the box can hold.
<h3>What is volume?</h3>
LSD use among secondary school understudies is a specific concern. More Volume is a proportion of consumed three-layered space. It is frequently evaluated mathematically utilizing SI inferred units or by different supreme units. Volume is characterized as the space involved inside the limits of an article in three-layered space. It is otherwise called the limit of article. Volume is a proportion of consumed three-layered space. It is frequently measured mathematically utilizing the SI determined unit, the cubic meter. The volume of a compartment is by and large comprehended to be the limit of the compartment, how much liquid (gas or fluid) that the holder could hold, instead of how much space the actual holder dislodges. Three layered numerical shapes are additionally relegated volumes.

Answer:
12
Step-by-step explanation:
a² + b² = c²
a² + 9² = 15²
a² + 81 = 225
a² = 225 - 81
a² = 144
a = 12
Answer:
a) Job A.
Step-by-step explanation:
Time, t = 2000 hours per year
Job A:
Salary = $13 per hour
Job B:
Salary = $11 per hour
Healfh insurance = $3400 per year
= $3400/2000
= $ 1.7 per hour
B:. Mb = $11 × 2000 = $22000
Health insurance costs 3400$ per year so while we are working our job A we have: so $11.3 × 2000 = $22600. So on job A we earn $600 per year more than on job B.
So if 4 boys each got $5 then the equation would be
4 x 5
They found 20 dollars.
