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>

Please can you answer It is due very soooooonn Will mark brainiest
Assoli18 [71]

Answer:

Mean of a grouped data is

Sum of F x/ sum of frequency F

Sum of F = 5 + 15 + 13 + 10 + 7 = 50

to find x find the average of the two classes

That's

0 + 10/2 = 10/2 = 5

10+20/2 = 15

20 + 30 / 2 = 25

30+40 /2 = 35

40+ 50 / 2 = 45

Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)

= 1240

Therefore

Mean = 1240/50

= 24.8cm

I hope this helps you

Find the distance between (2,3) and (5,8)
Orlov [11]
Use pythagorean theorem
a^2+b^2=c^2

first find the difference of between the 2 points to find the legnth of the legs

distance between 2 and 5=3
distance between 3 and 8=5 so


3^2+5^2=c^2
9+25=c^2
34=c^2
√34=c

the ligit formula is
c= \sqrt{(x1-x2)^2+(y1-y2)^2}
