How many pieces of stone slabs, each 24cm long and 15cm broad will be required to lay a path of 18m long and 12m wide?

6,000

Step-by-step explanation:

The computation of the number of pieces of stone slabs required is shown below:

The Area of the path is

= 18 × 12

= 216 square meters

= 2160000 square meters

And, the area of each stone slab is

= 24 × 15

= 360 square centimeters

So, the number of pieces of stone slabs required is

= 2160000 ÷ 360

= 6,000

answer is

c) 4

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
