The salinity of earths oceans,

→ a = 525 g

Amount of water for the salinity,

→ b = 15 kg

→ b = 15 × 1000

→ [ b = 15000 g ]

Then find the grams of salt for every gram of ocean water,

→ a ÷ b

→ 525 ÷ 15000

→ 0.035 g

Hence, answer is 0.035 grams of salt.

Answer:

<u>0.035 grams</u>

Step-by-step explanation:

<u>Grams of salt per gram of ocean water</u>

  • Divide the amount of salt by amount of water
  • 525 g / 15 kg
  • 525 g / 15000 g [∴1 kg = 1000 g]
  • 0.035 / 1

For every gram of ocean water, there is <u>0.035 grams</u> of salt dissolved in it.

What is the slope of the line through (-1,8) and (3,-4)?
laila [671]

Hey there!!

How do we find slopes ?

Slope = \frac{y2-y1}{x2-x1}

We are given with two co-ordinates :

(-1,8) and (3,-4)  

Hence, the slope is :

\frac{-4-8}{3+1}

... \frac{-12}{4} = -3

The slope is -3.

Hope my answer helps!

I DON'T KNOW WHAT TO DO WITH THIS. HELP
mixas84 [53]
Ok, so since she spent $15 each week for 10 weeks, she spent a total of $150 over those 10 weeks. The best approach I would use for this is cross multiplication. The total percentage of Books and music would be 35% out of 100% because 10+25=35. The answer is b, 50.

Hope this helps :)

Find the slope of the line that passed though the two points <br> (0,5) and (-9, -4)
OverLord2011 [107]

To find the slope, use the slope(m) formula:

m=\frac{y_2-y_1}{x_2-x_1}        and plug in the two points

(0, 5) = (x₁, y₁)

(-9, -4) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-4-5}{-9-0}

m=\frac{-9}{-9}    [two negatives cancel each other out and become positive]

m = 1      The slope is 1

A number is selected randomly from the integer from 10to30 what is the probability of picking a multiple of 4or5​
arlik [135]

Answer:

\frac{3}{7}

Step-by-step explanation:

Start by finding how many integers there are from 10-30...

30-10+1=20+1=21

Note we have to add 1 since it is inclusive.

Now, let's find how many multiples of 4 or 5 there are from 10-30...

4*3=12

4*4=16

4*5=20

4*6=24

4*7=28

5*2=10

5*3=15

5*4=20

5*5=25

5*6=30

5+5-1=9

Note we have to subtract 1 since 20 is counted twice.

The probability would be...

\frac{Multiples\ of\ four\ and\ five\ from\ 10-30}{Amount\ of\ integers\ between\ 10-30}=\frac{9}{21}=\frac{3}{7}
