Answer:
$2647.13
$2648.08
Step-by-step explanation:
To solve for the value of each loan we will use the formula:
Let's break down the variables that we have.
P = $2,600
r = 7.25% or 0.0725
r2 = 7.50% or 0.0750
t = 90 days
Now since we're computing for two different types of interest, let's take it one at a time.
First the State Saving and Loan.
In this situation we are solving for ordinary interest, where we compute with the total number of days are 360
The maturity value of State Savings and Loan is $2,647.13.
Now let's move on to the Security bank.
The security bank charges 7.5% exact interest. For exact interest we use 365 days.
The maturity value of the Security bank is $2,648.08.
Answer:
The sheet should be turned up 7.5cm on each side to obtain maximum volume.
Step-by-step explanation:
If we make a rectangular eavesdrop, by bending the sheet along dotted line, then.
Height of eaves trough = x cm
Length of eaves trough = 600 cm
Width of eaves trough = (30 - 2x) cm
We know that Volume is given by:
V = Length · Width · Height
V = (x)(30 - 2x)(600)
V = -1200x² + 18000x
To maximize the volume, we take the derivative and put it equal to zero.
Answer:
23%
Step-by-step explanation:
$1,771 divided by $ 2,300 = 77%
100% - 77% = 23%
Answer:
1km=1000m 160m=0.160x4=0.64
Step-by-step explanation:
Ifl = 160m, then:
P = 4 * 160m\\P = 640m
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: 1Km = 1000m
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
x = \frac {640 * 1} {1000}\\x = 0.64km
