Describe how you regroup when you find the sum of 64+43

Mathematics

Here, regrouping is basically carrying. 

64+43 shown vertically would be:

  64
+43
-------
 107
4+3 is 7, so seven is in the ones place, but that's not the point.
60+40 is 100, so you regroup by carrying the one to the hundreds place.

Hope I helped!

Answer:

400cm^2

Step-by-step explanation:

For this question, you need to find the surface areas of both objects, then add them together.

For the cube:

56cm for the front

56cm for the back

42cm for the side

42cm for the other side

48cm for the top

48cm for the bottom

SA for the cube: 292cm^2

For the triangle, things are a little different. We do the same process that we did to find the SA of the cube, but we do not have to find the SA of the top side (because there isn't a top side) and we have to divide the total SA by 2 because it's a triangle.

For the triangle:

42cm for the front

42cm for the back

54cm for the slanted side

42cm for the other side

36cm for the bottom

SA for the triangle: (216/2)^2=108cm^2

292+108=400cm^2

the SA of the composite figure is 400cm^2

Express 8.5454545454... as a rational number, in the form p/q where p and q are positive integers with no common factors.
zzz [600]
x=8.\overline{54}\\
100=854.\overline{54}\\
100x-x=854.\overline{54}-8.\overline{54}\\
99x=846\\
x=\dfrac{846}{99}=\dfrac{94}{11}

C is the correct answer


we should find the area of the square and then divide it by 24.
(360/15=24)


6 \times 6 \times \pi \times  \frac{1}{24}  = 36 \times \pi \times  \frac{1}{24}   \\  = 113.04 \times  \frac{1}{24}  = 4.71



good luck
