Given that Edward and Martin invested the same amount of $3500, with interest rate of 4.5% and time period of 10 years: The difference in the amount of money will be brought about by different schemes in which they both invested the money. 
The interest earned from above cash under simple interest will be:
S.I=(PRT)/100
S.I=3500*4.5/100*10=$1575
the total amount after 10 years will therefore be:
1575+3500
=$5075

The same amount if it was compounded annually, the amount after 10 years will be:
FV=P(1+r/100)^n
FV=3500(1+3.5/100)^10
FV=4,937.10
we therefore conclude that the answer is:
Edward must have earned simple interest while Martin earned compound interest.

Whats an approximate equation of a line that passes through the points (-4.3,2.3) and (1.3,-7.4)
Wewaii [24]
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)

Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)

Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.

7x &lt; 10<br> please solve
Anvisha [2.4K]

Answer: The answer would be  x < 10/7

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                    7*x (10)>0

Step by step solution :

STEP

1

:

Pulling out like terms

1.1     Pull out like factors :

  7x - 10  =   -1 • (7x + 10)

Equation at the end of step

1

:

STEP 2

:

2.1   Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     7x+10  < 0

2.2    Divide both sides by  7  

     x+(10/7)  < 0

Solve Basic Inequality :

2.3      Subtract  10/7  from both sides

           x < 10/7

Inequality Plot :

2.4      Inequality plot for

        7.000 x  - 10.000  >  0

 

One solution was found :

x < 10/7

den301095 [7]

Answer:

1 pound = 16 ounces

2 pounds = 32 ounces

Given:

Cost for 2 pounds of bananas = $1.28

Price per ounce = 1.28/32    [∵2 pounds = 32 ounces]

=$0.04

Hence the cost of bananas per ounce is $0.04

Hope it helped!

Answer:

7.5

Step-by-step explanation:
