Identify the percent of change as an increase or a decrease. 4/5 to 3/5

Mathematics
1 answer:
vovikov84 [41]4 years ago

Answer:

Decrease

Step-by-step explanation:

So, I encourage you to grab a calculator and see for yourself

Put in the function: 4/5 into a standard calculator. You will see that it will come out to .8

Put in the function: 3/5 into a standard calculator. You will see that it will come out to .6

.6 is less than .8, just as 3/5 is less than 4/5.

Another analogy that can be used is seeing the fraction as a real-life object.

Let's say that you make two pies. You cut the pie evenly into five slices. You set them on the table and leave them for whoever wants to eat them. You see that Pie 1 has two slices missing (3/5) and that Pie 2 has one slice missing. (4/5)

3 out of 5 slices are left of Pie 1.

4 out of 5 slices are left of Pie 2.

Pie 1 has less than Pie 2 does.

Hope this has helped!

Drag each expression to show whether it can be used to find the volume, surface area, or neither.
Mumz [18]

Answer:

Volume = 12 *6 *8 , Surface area = 2 ( 12 *6  + 8 *12 + 6* 8 )

Step-by-step explanation:

Given : Cuboid with length 12 , width 6 and height 8 units.

To find : Drag each expression to show whether it can be used to find the volume, surface area, or neither.

Solution : We have given Cuboid with

Length =  12 units ,

Width = 6 units

Height = 8 units.

Volume of cuboid = length * width * height .

Volume = 12 *6 *8.

Surface area = 2 ( l *w  + h *+w *h)

Surface area = 2 ( 12 *6  + 8 *12 + 6* 8 ).

None = 12 +6 +8.

Therefore, Volume = 12 *6 *8 , Surface area = 2 ( 12 *6  + 8 *12 + 6* 8 ) .

Answer:

= 100

Step-by-step explanation:

TSA of brick → 2(L×b+b×h+h×l)

= 2(22.5× 10 + 10 \times  7.5 +7.5 \times 22.5)

= 2 (225 +75 + 168.75) cm²

=2 ( 468.75) cm ²

= 937.5cm²

=  \frac{937.5 {cm}^{2} }{100 \times 100} =0.09375 m²

Therefore, Required number of Bricks-

=  \frac{9.375 {cm}^{2}  \times 100}{0.09375  \: {cm}^{2} }

= 100

  • Hence,The required Number of Bricks = 100 respectively.
