There is 75% of shirts left to do, split over 5 days, you can divide 75 by 5 to get 15% each day.

As a fraction you need 3/4 to be done over 5/1 days

divide 3/4 divided by 5/1

copy, change, flip

3/4   x    1/5

3x1=3
4x5=20 that's 3/20 if you divided that into a percentage its also 15% so you know you're right. 

For part 2, that's simple because you can decide if 40 shirts includes the 1/4 you already did.  In that case find out what 40/4 is.  That's 10.  If you did 10, you need to do 30 more.  That would mean that 30/5 because there is 5 days.  30/5 is 6.  6 would be for 1 day, you need to know 2.  That's 12. 

If 40 does not include the 1/4 you already did, and it's 40 remaining.  You'd have to do 40/5 which is 8.  Then 8x2 is 16. 

But I think the other person is correct, it would be 40 total so it should be 12 shirts.

A. If she completed 1/4, 3/4 are still left to be done over 5 days.
To find out how much per day, divide 3/4 by 5 (multiply the first number by the reciprocal of the second).
3/4*1/5= 3/20.

Final answer: 3/20

b. If she irons 3/20 a day, she should iron 6/20 or 3/10 over the course of two days, Thursday and Friday. 3/10 of 40 is 40*0.3= 12

Final answer: 12 shirts

In the figure, what is the value of x?
masha68 [24]

Answer:

  90

Step-by-step explanation:

In the quadrilateral formed by two tangents and the associated radii, the central angle and the external angle are supplementary. Here, that means that x° is supplementary to itself, so must be 90°.

  x = 90

Emmanuel carves a cone-shaped hollow out of a solid clay cylinder. What is the approximate volume of the solid portion of the cy
bixtya [17]

Answer:

3.14r^2(h-\frac{1}{3}h_1)

Step-by-step explanation:

Let h be the cylinders height and r the radius.

-The volume of a cylinder is calculated as:

V=\pi r^2h

-Since the cone is within the cylinder, it has the same radius as the cylinder.

-Let h_1be the height of the cone.

-The area of a cone is calculated as;

V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi r^2h_1

The volume of the  solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:

V=V_{cy}-V_{co}\\\\=\pi r^2h-\frac{1}{3}\pi r^2 h_1, \pi=3.14\\\\=3.14r^2(h-\frac{1}{3}h_1)

Hence, the approximate area of the solid portion is 3.14r^2(h-\frac{1}{3}h_1)

What of the following exponential functions is represented by the data in the table?
patriot [66]

Answer:

f(x) = ( 1/3) ^ (x)

Step-by-step explanation:

The function is

f(x) = (1/3) ^ (x)

When x = 1  f(x) = 1/3

when x=2    f(x) = 1/9

When x = -1  f(x) = ( 1/3) ^ -1 = 3/1 =3
