which of the following gear ratios will have the highest
overall speed?
o 2.26
o 2.87
o 3.5
04.63

4.63

Step-by-step explanation:

we know that

The gear ratio is the ratio between the driver gear and the driven gear .

if the drive gear (the one directly receiving rotational force from the engine, motor, etc.) is bigger than the driven gear, the latter will turn more quickly, and vice versa.  

Higher the gear ratio value, higher will be the speed.  

so

Of the 4 gear ratio values given, 4.63 is the highest and hence this gear ratio will have the highest overall speed

therefore

4.63 will have the highest overall speed

i really dont know

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
