Nutka1998 [239]

Answer:

1900

Step-by-step explanation:

1 kg = 1000g

1.2kg = x

<u>1</u><u> </u><u>kgx</u> = <u>1</u><u>2</u><u>0</u><u>0</u><u> </u><u>kg.g</u>

1kg. 1kg

x = 1200 g

1 decagram = 10g

40 decagram = x

<u>1</u><u> </u><u>dg.x</u> = <u>4</u><u>0</u><u>0</u><u> </u><u>dg.g</u>

1 dg. 1 dg

x = 400g

so the total= 1200g +300 + 400g=1900g

without the unit = 1900

Jobisdone [24]
Volume = length x width x height or V = lwh as a formula if you will.

Let's substitute what we know into the formula:

100 = 4(5)h multiply the 4(5) on the right side
100 = 20h divide both sides of the equation by 20
5 = h

the height of the rectangular box is 5 feet

Could someone help me ASAP !!
Lelechka [254]

Answer:

LSA = 592cm^2.

Step-by-step explanation:

Well LSA is the SA but without the base so the blue square does not count.

So we have to find the area of the triangle which is b*h/2.

So 18.5*16 / 2 is 148.

And since there is 4 triangles with the same dimensions we do 148*4, 592cm^2.
