Mr. Noel borrowed money from his cousin at a rate of 10% simple interest. After 1 year, $440
Alborosie

Answer:

<h2>$400</h2>

Step-by-step explanation:

Using the formula for calculating the simple interest expressed as;

Simple Interest = Principal * rate * time/100

Note that the principal is the amount he originally borrowed

I = PRT/100 ............ 1

Amount paid off A = Principal+Interest

A = P+I ............ 2

From equation 2; I = A-P......... 3

Substitute equation 3 into 1;

A-P = PRT/100

Given A = $440, R = 10%, Time = 1year

Substitute the given parameters into the resulting equation;

440 - P = P*10*1/100

440-P = 10P/100

440-P = 0.1P

440 = 0.1P+P

440 = 1.1P

Divide through by 1.1;

1.1P/1.1 = 440/1.1

P = $400

<em>Hence the amount Mr Noel originally borrow is $400</em>

Tanzania [10]

Answer:

f6h40

Step-by-step explanation:

Step  1  :

           h23

Simplify   ———

           f3  

Equation at the end of step  1  :

         h23

 ((f9) • ———) • h17

         f3  

Step  2  :

Multiplying exponential expressions :

2.1    h23 multiplied by h17 = h(23 + 17) = h40

Final result :

 f6h40

Look at the figure shown below​
Setler79 [48]

Answer:

<em>Answer is </em><em>given below with explanations</em><em>.</em>

Step-by-step explanation:

Answer is option 1) 85 : 51

given \: that \:  \\ triangle \: SPT \: is \: similar \: to \: triangle \:  QPR \\ corresponding \: sides \: of \: similar \:  \\ triangles \: are \: in \: proportion \\ then \:  \\  \frac{SP}{ QP}  =  \frac{PT }{ PR}  \\  \frac{3x}{3x + 24}  =  \frac{51}{85}  \\ taking \: reciprocal \: on \: both \: sides \\  \frac{3x + 24}{3x}  =  \frac{85}{51}

Option 1 is correct.
