The weight of 10,000 identical samples is 100 pounds. what is the weight of 10 samples
Ann [662]

We can write a proportion

10,000 identical samples is 100 pounds

10 identical samples is x pounds

10000/10 = 100/x

10000x=10*100

x=1000/10000=1/10=0.1

x=0.1 pound

10 samples have the weight 0.1 pound.

Answer:

The. angle is 72 and the supplement is 108

Step-by-step explanation:

Supplementary agnles are two angles with a sum of 180. So for example, two right angles would be supplementary.

Once again lets break this down by putting it into an equation. The supplement will be x. We know that 180 - x ( the supplement) will be equal to the angle but the angle is 2/3 the supplement.

Your equation should look like this x = 2/3 (180 - x).

Then we're going to multiply both sides by 3 to get 3x = 2 (180 - x)

You should distribute the 2 on the right side to then get 3x = 360 - 2x

You want to get x by itself but you can't make it just disappear because you need to keep your equation balanced. You're going to need to add 2x to both sides making your equation 5x = 360.

then you're going to divide 360 by 5 to get x = 72

subtract 72 (your angle) from 180 to get 108 which is your supplement.

If it's a bit confusing feel free to msg me and I'll do my best to explain it a bit better ^^;

#8) Subtract 350 from each side then divide each side by 25 to get (c-350)/25 = h.

Plug in 950 for c to get (950-350)/25 = h.
600/25 = h = 24 hours.

#9 is the same as number 8 just with one more variable. Subtract 2.25h from both sides and divide both sides by 1.75. Then plug in 18.25 for t and 5 for h. Then solve for d.

CONSIDERANDO QUE A U B= { 1,2,3,4,5,6,7,8}, A U B = {4,5} e A-B = { 1,2,3}, DETERMINE O CONJUNTO B
fenix001 [56]

Answer:

O conjunto B é dado por: B = {4, 5, 6, 7, 8}

Step-by-step explanation:

A U B= { 1,2,3,4,5,6,7,8}

Todos os elementos pertencem a pelo menos um desses conjuntos.

A intersecção B = {4,5}

Os elementos 4 e 5 pertencem a pelo menos um desses conjuntos. Então, tem-se os dois primeiros elementos de B, que são 4 e 5.

A-B = { 1,2,3}

1, 2, 3 são os elementos que pertencem ao conjunto A e não pertencem ao conjunto B.

Como A U B= { 1,2,3,4,5,6,7,8}, tem-se que os elementos 4, 5, 6, 7 e 8 pertencem ao conjunto B.

O conjunto B é dado por: B = {4, 5, 6, 7, 8}
