A machine paints 34o toy boats im 3/4 of an hour how many boats can he make per hour
leonid [27]
Here, we can set up a proportion:

34 ÷ 3/4 = ? ÷ 1
34*1 = 34
34÷3/4 = the time needed to build one toyboat

34/3/4 = 45.3333333333

45.3 repeating is not a whole number, so we need to approximate. 

45 is the closest whole number, 

So.. a machine can paint 45 toy boats per hour. 

I really hope that helped! :)

C= 2(3.13)21

C= 6.28 • 21 = 131.88

131.88 rounded is 132

Mrs.smells math class has 20 questions worth 100 points. if the multiple choice are worth 3 points and the short answer is worth
andreyandreev [35.5K]
Let, Number of multiple choice = x
Number of short answer question = y

Now, x + y = 20
& 3x + 11y = 100

Multiply 1st equation by 3, and subtract from eq,2, 
3x + 3y = 60
After subtraction, 
8y = 40
y = 40/8
y = 5

Now, substitute in eq (1), 
x + 5 = 20
x = 15

In short, There are 15 Multiple choice & 5 short answer questions

Hope this helps!
