Answer = 36.0 mph



As per the question,



Actual speed of the car = 40 mph.


Speedometer has a percent error of 10%.


The error can be negative as well as positive.


If the error is negative, it means speedometer is showing less speed than actual speed= - 10%


10  % of 40 = 4


speed shown by speedometer = 40 - (10% of 40) = 36 mph


If the error is positive, it means speedometer is showing more speed than actual speed = +10%


speed shown by speedometer = 40 + ( 10% of 40) = 44 mph


as per the given options, correct option is 36.0 mph

Frank mary and seth shared some sweets in the ratio 4:5:7 seth got 18 more sweets than frank
Nimfa-mama [501]

Answer:

each number in the ratio 4:5:7 is worth 6 sweets. add 4,5, and 7 to get 16 then multiply it by 6 to get 96 sweets.

Step-by-step explanation:

add the ratios = 4+5+7= 16

1 number = 6 so

4x6= 24

5x6=30

7x6=42

Frank gets 24 sweets

Mary gets 30 sweets

Seth gets 42 sweets

The total number of sweets they shared is 24+30+42= 96

The share 96 sweets altogether.

The check your answer; do 42-24= 18

Therefore, now we know that the difference between Seth and Frank's amount of sweets is 18.

Therefore, this is correct.
