How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

Answer:
Step-by-step explanation:
you can do many things to add 3/4, most common way si thinking of 3/4 3 quarters of your number
you can add 3/4 to 1 which is 1 3/4
1+3/4=1 3/4
or,
you could do
3/4 OF 10 is 3 quarters of 10 which is 2.5x3 or 10 -2.5 which equals,
7.5
Answer:
You can add 3/4 by adding as a decimal so 3/4 of 100 is 75 so it would be .75
Step-by-step explanation:

Please help. You will get some points.
Answer:
1) x: small #; y: large #
4y = 7x
x + y = 22
----------------
-7x + 4y = 0
x + y = 22
---multiply the second equation by -4------
-7x + 4y = 0
-4x - 4y = -88
----solve------
-11x = -88
x = 8
---substitute with any of the equation above i chose the very first one------
4y = 7(8)
4y = 56
y = 14
x = 8; y = 14
2) x = small #; y = large #
y - x = 15
5x = y - 9
----after rearranging, solve-----
-x + y = 15
5x - y = -9
-4x = 6
x = -1.5
--------substitute--------
-(-1.5) + y = 15
1.5 + y = 15
y = 13.5
x = -1.5; y = 13.5
3) x = lemon cream; y = fudge cookie
3x + 2y = 400
2x + 3y = 425
----multiply the first equation by -2, multiply the second equation by 3------
-6x - 4y = -800
6x + 9y = 1275
----solve------
5y = 475
y = 95
--------substitute--------
3x + 2(95) = 400
3x + 190 = 400
3x = 210
x = 70
x = 70; y = 95
An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?
9514 1404 393
Answer:
2709.7 square inches
Step-by-step explanation:
If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.
larger area = 49(55.3 in^2) = 2709.7 in^2

What is 2+4+6-9+17-4=x
Answer:
x = 16 or 16 = x
Step-by-step explanation:
2+4+6-9+17-4=x
6+6-9+17-4=x
12+17-9-4=x
29-9-4=x
20-4=x
16=x
Answer:
[tex]x = 16[/tex]
Step-by-step explanation:
[tex]2 + 4 + 6 = 12[/tex]
[tex]12 - 9 = 3[/tex]
[tex]3 + 17 = 20[/tex]

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?
please drop an explanation, and equation thanks!
Answer:
1 kg of baking soda costs $4.50.
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
4/9 kg $2
------------- = --------------
1 kg x
Multiplying both numerators by 9, we get:
4 kg $18
------------ = ---------
1 kg x
Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:
$18-kg
x = -------------- = $4.50
4kg
1 kg of baking soda costs $4.50.
