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:
D
Step-by-step explanation:
Now add the populations in scientific notation.
Rewrite each estimate so they all have the same power of 10.
Dogs: 69,900,000
Cats: 36,100,000
Birds: 8,300,000
Answer:
question 1 part a =
estimated number of dogs
=6.99 × 107
= 6.99 • 10,000,000
= 69,900,000
estimated number of cats
= 3.61 × 107
= 3.61 • 10,000,000
=36,100,000
estimated number of birds
= 8.3 × 106
= 8.3 • 1,000,000
= 8,300,000
part b = total population of pet dogs, cats, and birds
= 69,900,000 + 36,100,000 + 8,300,000
= 114,300,000
question 2 part a =
The estimated number of dogs is 6.99 x 10^7 .
The estimated number of cats is 3.61 x 10^7.
The estimated number of birds is 8.3 x 10^6.
The power of 10 in 8.3 x 10^6 is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.
Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:
8.3 x 10^6 = 10/10 x 8.3 x 10^6
= 8.3/10 x 10^6 x 10
= 0.83 x 10^7
part b =
total number of pet dogs, cats, and birds
=
6.99 × 107 + 3.61 × 107 + 0.87 × 107
=
(6.99 + 3.61 + 0.83) • 107
=
11.43 • 107
part c =
No. The sum from part B is not in scientific notation.
The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:
10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10
= 1.143 x 10^8
Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.
question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

Cats: 3.61 x [tex]10^8[/tex]
Birds:0.083 x [tex]10^8[/tex]
What is Scientific Notation?Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.
Given:
We have to change the number in Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.
First, Dogs: 69,900,000 whose Scientific Notation is
= 6.99 x [tex]10^8[/tex]
Second, Cats: 36,100,000 whose Scientific Notation is
= 3.61 x [tex]10^8[/tex]
Third, Birds: 8,300,000 whose Scientific Notation is
= 8.3 x [tex]10^6[/tex]
= 0.083 x [tex]10^8[/tex]

A customer suspects that one brand of cereal does not fill its boxes with the weight that is printed on the box. He decides to weigh several boxes to test his theory.
Which of these methods will produce the most representative sample of the population of boxes containing this brand of cereal?
A). The customer randomly selects one grocery store, weighs one case of the cereal, and uses this weight to estimate the weight per box.
B). The customer randomly selects four grocery stores and weighs two boxes from each selected store.
C). The customer randomly selects one grocery store and weighs half the boxes of cereal.
D). The customer randomly selects one grocery store and weighs all the cereal boxes on one shelf.

At a school, each class period is 3/4 hour long. If there are 6 hours of class time in a school day, how many class periods are there?
Answer:
2 im thinking this so tell me if i got it wrong
Step-by-step explanation:
There are 8 class periods in total in the entire school day.
According to the question,
each class takes 3/4 hrs i.e., 3/4 hrs per class
and total hours of class in a day = 6 hrs
Therefore, to identify the number of classes in a day we divide the total hours of class in a day with the time of each class. These can be shown as follows
= 6 hrs / (3/4) hrs/class
= 6 ×4/3 hrs×class/hrs (units)
= 2 × 4 class
= 8 class periods
Therefore, the total no. of class periods are 8.

Hello!
A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).
On interval 1, the function is not increasing since the y value stays constant.
On interval 2, the function is increasing because the y values are increasing.
On interval 3, the function decreases because the y values are decreasing.
On interval 4, the function increases again.
On interval 5, the function stays the same because of its constant y value.
To reiterate, on intervals 2 and 4, the function is increasing.

Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.
Answer:
Inequality: .80x +21 ≤ 82
Answer: 76.25 miles in total
Step-by-step explanation:
Hi,
An inequality to represent this is .80x +21 ≤ 82
(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).
Now we solve...
.80x + 21 ≤ 82
Subtract 21 on both sides...
.80x ≤ 61
Now, divide by .80 on both sides...
x ≤ 76.25
He can drive up to 76.25 miles in total
