Answer:
$840
Step-by-step explanation:
Given data
Principal = $3000
Rate= 7%
Time= 4 years
The expression for the simple interest is
SI= PRT/100
substitute
SI= 3000*7*4/100
SI= 30*7*4
SI= $840
Hence the interest is $840
Answer:
The cost of the fencing is $273
Step-by-step explanation:
* Lets explain how to solve the problem
- Sam is planning to fence his back yard
- Every side of the yard except for the side along the house is to
be fenced
- The fencing costs $3/yd and can only be bought in whole yards
- The side of his yard opposite the house measures 35 yd
- The other two sides of his yard are 28 yd
* Lets solve the problem
∵ The length of the yard is the sum of the sides whose to be fenced
∴ The length of the yard = 28 + 35 + 28 = 91 yd
∵ The cost of the fencing is $3 per yard
∴ The cost = 91 × 3 = 273
∴ The cost of the fencing is $273
let's recall that the sum of all interior angles in a triangle is 180°, so then
6000. All you have to do is multiply lengthxwidthxheigth
