Two fifth graders solved 400,000 divided by 800. Carter said the answer is 500, while Kim said the answer is 5,000.
mestny [16]

Answer:

a. Carter is correct. (See explanation).

b. The quotient is 500 (The quotient of 400,000 divided by 800 and the quotient of  is 4,000,000 divided by 8,000 are equal).

Step-by-step explanation:

a. Carter is correct.

The dividend 400,000  and the divisor 800 have two zeros in common, so we can eliminate those zeros. Then:

4,000\div8

We know that the quotient obtained by dividing 40 and 8 is 5:

40\div8=5

 Since4,000 has two more zeros than 40, we must place two zeros in the quotient. Then:

=500

b. The dividend 4,000,000  and the divisor 8,000 have three zeros in common, so we can eliminate those zeros. Then:

4,000\div8

Notice that this is the same as the exercise "a". So the quotient will be the same.

Let's check. We know that:

40\div8=5

 Since4,000 has two more zeros than 40, we must place two zeros in the quotient. This is:

=500

Help.me its urgent<br>Find the total surface area and volum of given prism​
Marat540 [252]

Answer:

Total surface area = 434 cm²

Total volume = 470 cm³

Step-by-step explanation:

1. The prism can be decomposed into two rectangular prisms which are the bigger rectangular prism and the smaller rectangular prism

✔️Total surface area of the prism = (surface area of the bigger prism - area of the face joined to the smaller prism) + (surface area of the smaller prism - area of the face joined to the bigger prism)

Surface Area of bigger prism = 2(LW + LH + HW)

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Area of bigger rectangular prism = 2(10*4 + 10*8 + 8*4)

= 304 cm²

Surface area of the smaller prism = 2(LW + LH + HW)

L = 10 cm

H = 3 cm

W = 5 cm

Area of bigger rectangular prism = 2(10*5 + 10*3 + 3*5)

= 190 cm²

Area of the face joining both rectangular prisms = L*W

L = 10 cm

W = 3 cm

Area = 10*3 = 30 cm²

✅total surface area of the prism = (304 - 30) + (190 - 30) = 274 + 160 = 434 cm²

2. Volume of the prism = volume of the bigger rectangular prism + volume of the smaller rectangular prism

✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Volume = 10*8*4 = 320 cm³

✔️✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 3 cm

W = 5 cm

Volume = 10*3*5 = 150 cm³

✅Total Volume of the prism = 320 + 150 = 470 cm³

The slope between points A and B is 3/5. The slope between points B and C is 6/10 . Antoine says all three of these points are o
photoshop1234 [79]

If we reduce the slope between points b and c

6/10 divide the top and bottom by 2

3/5

A to B and B to C have the same slope

They are the same line, since point B is the same point
