We know there are 60 minutes in an hour. To find 2/3 of an hour we divide 60/3 to find 1/3 and multiply by 2 so:
60/3 = 20
20*2 = 40 minutes (which is 2/3 of an hour) to do science
We do the same thing with the 40 minutes. To find 1/4 of 40 minutes we divide 40 by 4 and then multiply it by 3 to get 3/4 so:
40/4 = 10
10*3 = 30 minutes
Then subtract the times 40-30 = 10 minutes
It took her 10 more minutes to complete her science homework.

The amount of butterscotch chips needed by proportional reasoning according to the task content is; 75oz.
<h3>What is the quantity of butterscotch chips needed according to the task content?</h3>
It follows from the task content that the proportion premise given is that; 3 times as many chocolate chips as butterscotch chips is required.

Answer:
it is A i think i am a nub tho
Step-by-step explanation:
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
10x and 2x is the answer to your question then do the equation
