Answer:
x: work a woman can do in 1 day
y: work a girl can do in 1 day
Then
2x + 7y =1/4
4x + 4y =1/3
4x + 14y =2/4 (1)
4x + 4y =1/3 (2)
=> Let (1) - (2), 10y =2/4-1/3 <=>10y = 1/6 <=> y = 1/(6x10) = 1/60 (work)
=> From (2),4x = 1/3 - 4x1/60 => 4x = 16/60 => x = 4/60 (work)
=> 1 day, a woman and a girl can do: 1/60+4/60 = 5/60 =1/12 (work)
Then, the day required for a woman and a girl to complete work: 12 days
Your answer is C. 16 this is the possible answer
Rice: .5(8) = 4kg (4000 g)
Popcorn: 150(12) = 1800 g
Total mass = mass of rice (4000 g) + mass of popcorn (1800g)
So...
Total mass = 5,800 g (or 5.8 kg)
Answer:
Alright well use the Graph line using the slope and the y-intercept, or two points
Slope: - 1
y - intercept: - 2
X: 0, 1
Y: - 2, - 3 Hope this helps :)
Step-by-step explanation:
We have to compare diameters and arrange them in order smallest to greatest
We can see units for option A and B are in square inches so they represents area. So first we will find diameter from area using formula

so for choice (A) area is given as
. So plug this in A place in formula and then solve for radius r




3731.76 = r
So screw A will have
inches
Similarly for choice (E) area is 
so again plug in formula





2.13201 = r
So screw E will have
inches
So diameters of all screws are as follows:
Screw A: 7463.52 inches
Screw B: 1.5 inches
Screw C:
inches
Screw D: 0.25 inches
Screw E: 4.26402 inches
Comparing all numbers 7463.52, 1.5, 1.875, 0.25, 4.26402 we can see that smallest number is 0.25, then comes 1.5, then 1.875 and then 4.26402 and then 7463.52
So order from least to greatest will be screw D (0.25), B(1.5), C(1.875), E (4.26402), A (7463.52).
So thats the order D,B,C,E,A and the final answer
