A footpath 16 m 80 cm long should be paved with stones 60 cm long. How many stones are needed?​

Mathematics
1 answer:
Annette [7]3 years ago
5 0

Answer:

28 stone bricks are necessary for this footpath.

Step-by-step explanation:

lets start by remembering that 1m has 100cm, therefore 1m = 100cm.

That being said we transform everything to centimeters since the stones are in centimeters.

16 m + 80 cm = 16 × (100 cm) + 80 cm

1600 + 80 = 1680 cm.

If every stone is 60 cm long, we need to divide our footpath length by the stone length to know how many stones are needed, therefore:

1680 cm / 60 cm = 28 bricks!!

I hope it helps :)

Bill deposits $3,000 into an account that pays simple interest at a rate of 3% per year. How much interest will he be paid in th
Sholpan [36]

Answer:

The interest he will be paid in the first 4 years is $360

Step-by-step explanation:

The rule of the simple interest is I = Prt, where

  • P is the initial deposit
  • r is the rate in decimal
  • t is the time

∵ Bill deposits $3,000 into an account

∴ P = 3000

∵ The account pays simple interest at a rate of 3% per year

∴ r = 3% = 3 ÷ 100 = 0.03

∵ The time is 4 years

∴ t = 4

→ Substitute these values in the rule above

∵ I = 3000(0.03)(4)

∴ I = 360 dollars

∴ The interest he will be paid in the first 4 years is $360

The points (0,2) and (1,5) are on a line which of these points is on the same line
katrin [286]

Answer:

y = 3x + 2

Step-by-step explanation:

The equation for two points on a line is generated from the straight line equation y = mx + b ---------------- eqn (i)

where m, the slope = (y2 - y1) / (x2 - x1)  

therefore for (0,2) and (1,5) m = (5 - 2)/(1 - 0) = 3

This implies that eqn (i) can be rewritten as:

y = 3x + b ------------------- eqn (ii)

pickintg the point (0,2) and substituting into eqn (ii)

2 = 3(0) + b

this implies that b = 2

for confirmation with (1,5)

5 = 3(1) + b

b = 5 - 3 = 2

hence m = 3, b = 2

the equation is y = 3x + 2

How do you find the width of a rectangle when the perimeter is given?
ololo11 [35]
Usually you are given more information about the rectangle such as distance of length in terms of width.

You know that the formula for perimeter is

P=2(l+w)

Substitute p and the other values to find width.

Hope I helped :)
