darcy likes to eat peanut butter and raisins on apple slices. on each apple slice she puts 1/16 cup of peanut butter and 8 raisi

netineya [11]

The answer is 7/10.

For one apple slice, Darcy needs 1/16 cup of peanut butter and 8 raisins. She has 2/5 cup of peanut butter. To compare how many butter she has and she needs we will divide 2/5 with 1/1

This means that Darcy needs 5/80 cup of peanut butter and 8 raisins.
If she has 32/80 cup of peanut butter, she will have it only fo 6 or 7 apple slices (32/80 ÷ 5/80 = 6.4) depending how it is rounded. If she prepares 6 apple slices, she will still have a little of peanut butter left (0.4 = 2/5 of cup). So, she will prepare 7 apple slices so the butter will be all gone.

For 7 apple slices, she needs 56 raisins (7 × 8 raisins).
That is 56 raisins out of 80 raisins, so fraction of the 80 raisins did she eat is:
 $\frac{56}{80} = \frac{7}{10}$

What is 5x+3y=-15 slope intercept form

muminat

Slope intercept form is y = mx + b
All we really have to do is rearrange our equation!
Subtract 5x from both sides
3y= -5x - 15 is your slope intercept form.

Substitute teachers with Silvergrove School District get paid by the day, although subs with teaching credentials earn a differe

Firdavs [7]

Answer:

subs with credentials get paid $87 per day. subs without credentials get paid $55 per day.

Step-by-step explanation:

let x be the cost subs with credential get paid per day and y be the cost subs without credential get paid per day

so we get

$4x + 6y = 678 \\ 3x + 11y = 866$

using simultaneous equation by substitution method you get x=87 and y=55

Divide of a right angle into two parts such that the number of English minutes in one to the

stira [4]

Answer:

π/3 radians, 3600 English minutes
π/6 radians, 333,333 1/3 French seconds

Step-by-step explanation:

An English minute is (1/60)(π/180) radian = π/10800 radian.

A French second is (1/100)(1/100)(π/200) radian = π/2000000 radian.

So, the ratio of angle sizes in common units will be ...

27(π/10800) : 2500(π/2000000) = (2/800) : (1/800) = 2 : 1

Since the total of these ratio units is 2+1 = 3, we need to divide the right angle into 3 parts. The English part will be 2 of those; the French part will be 1 of them. A 1/3 part of a right angle is π/6 radians, so the right angle division will be ...

English : French = π/3 radians : π/6 radians

= 3600 English minutes : 333,333 1/3 French seconds

= 27 : 2500
