Answer:

220 km  

Step-by-step explanation:

Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle.  The hypotenuse is his displacement for the combination of the two segments.

    D = √(215² + 45²)

        =  √(46,225 + 2,025)

        =  √48,250  =  219.6588... km

Nearest whole number:   220 km

Answer:

s = 6 cm

Step-by-step explanation:

the area (A) of a square is calculated as

A = s² ( s is the side length )

s² = 36 ( take square root of both sides )

6 sweets cost 42p altogether how much do 8 sweets cost
Eddi Din [679]
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
