Answer:

105 miles on map

Given data

Distance on map= 17cm

scale= 5 centimeters on the map as 30 miles on the road

hence

if 5cm rep 30 miles

17cm rep x

cross multiply

5*x= 17*30

x= 510/5

x= 105 miles

Hence the distance is 105 miles on map

Tossing a regular coin 3 times, what is the probability of getting heads every time? 4)
larisa [96]

The probability of getting heads on the first toss is  1/2 .

Then, the probability of getting heads on the second toss is  1/2 .

Then, the probability of getting heads on the third toss is  1/2 .

The probability of all three things happening is ...

                 (1/2) x (1/2) x (1/2)  =  1/8  =  0.125  =  12.5% .

If an electric kettle uses
cupoosta [38]

Answer:

The energy used in 3.5 hours = 5.25 kilowatts            

Step-by-step explanation:

Energy used by electric kettle:  

  • 2\frac{1}{4}=\frac{9}{4}=2.25 kilowatts

Time taken by electric kettle:

  • 1.5 hours

Electric kettle's rate in kilowatts per hour can be calculated by dividing the spent energy i.e. 2.25 kilowatts by the time taken i.e. 1.5 hours.

Therefore,

Electric kettle's rate = 2.25 kilowatts / 1.5 hour

                                  = 1.5 kilowatts per hour

Thus, the energy used in 3.5 hours = 1.5 × 3.5

                                                           = 5.25 kilowatts

Therefore, the energy used in 3.5 hours = 5.25 kilowatts

2x^2-4x+7=0 a=2 b=-4 c= 7



disctirminant =b^2-4ac


disctirminant =(-4)^2-4.2.7


disctirminant = 16-56= -40


x=-b+square root of disctirminant ÷2a


x=4+2square root of (-10)/4


x=2+square root of (-10)/2


x'=4 -2 square root of (-10)/4


x'=2 -square root of (-10)/2
