Answer: .4 is larger
Step-by-step explanation:
30% is equivalent to .3 whereas 40% is equivalent to .4
There is 20 students in her class.
Ex.
3/10= size of slice; you can get 3 slices from one pizza.
There are 6 pizzas..... 3x6=18; there will be a remained of 1/10 from each pizza because 3/10 is not an even number. Now u would have (6) 1/10's.... So 1/10+1/10+1/10= 3/10 and 1/10+1/10+1/10=3/10..... That makes two more slices for two more students...... 18+2=20 slices for 20 kids in the class! :-)

Answer:
<em>The larger gear will rotate through 156°</em>
Step-by-step explanation:
<u>Arc Length</u>
The arc length S of an angle θ on a circle of radius r is:
Where θ is expressed in radians.
The smaller gear of r1=3.7 cm drives a larger gear of r2=7.1 cm. The smaller gear rotates through an angle of θ1=300°.
Convert the angle to radians:
The arc length of the smaller gear is:
The larger gear rotates the same arc length, so:
Solving for θ2:
The larger gear will rotate through 156°
For this type of question, we have to take out the percentage of each candidate:
For Arthur
85 from 95
Convert 95 to 100
That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got 90% For Miguel 64 from 76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%
