Answers

Answer 1
3 is the correct answer
Answer 2

The scientific estimated form of the numbers are,

0.0000000043 = 4×10⁻⁹, 43560000000 = 4×10¹⁰, 56234567 = 5×10⁷, 0.000023456 = 2×10⁻⁵.

What is scientific notation?

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in the scientific form in a compact manner.

The number 0.0000000043 has 9 digits after the decimal so the estimated as 4×10⁻⁹.

The number 43560000000 can be written as 4×10¹⁰.

The number 56234567 can be written as 5×10⁷.

The number 0.000023456 can be written as 2×10⁻⁵.

Which of the following best describes the location of the polar easterlies?
Group of answer choices

B 0 to 30 degrees north latitude

C 60 to 90 degrees south latitude

D30 to 60 north and south latitude

Answers

Answer:

best describes the location of the polar easterlies?

Step-by-step explanation:

Polar easterlies The polar easterlies (also Polar Hadley cells ) are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes. [ 1 ]

hope this helped :)

Among all the given descriptions, the one that describes the location of the polar easterlies is: “60 to 90 degrees north and south latitude.” Hence, Option A is correct.

What are polar easterlies?

Dry, chilly polar easterlies are the dominant winds that originate in the east. They come from the polar highs, which are pressure ridges located around the North and South Poles.

Low-pressure zones in subpolar regions receive polar easterlies. At midlatitudes, the dominant winds are westerlies, which originate in the west.

Polar easterlies are the cold, dry, and dominant winds that surround the high-pressure zones of the polar highs at the North and South Poles in the study of Earth's atmosphere.

The constant winds that blow in the middle latitudes are known as westerlies. They blow in the direction of subpolar low pressure belts from subtropical high pressure belts.

Compared to the westerlies in the Northern hemisphere, the westerlies in the Southern hemisphere are stronger and more reliable.

Therefore, Option A is correct.

On the graph, two right triangles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope between points E and A is the same as the slope between points A and C.


Q1:
Which angles of the triangles measure 90°?

Q2: To show that the other two angle measurements in each triangle are equal, you can use parallel lines cut by a transversal. Which two pairs of line segments formed by triangle sides are parallel, and what is the transversal for each pair?

Answers

Answer:

1.The 6th one

2. The pairs can be (6, 8)

Step-by-step explanation:

We know that, the Slope is always given as [tex]\bold{\dfrac{Rise}{Run}}[/tex], where the rise is the vertical height of the slope and run is the horizontal length of the slope.

For Δ ADE,

rise = DE = 4 units,

run = DA = 6 units,

[tex]\bold{slope = \dfrac{Rise}{Run} =\dfrac{4}{6} = \dfrac{2}{3}}[/tex]

For Δ ABC,

rise = AB = 2 units,

run = BC = 3 units,

[tex]\bold{slope = \dfrac{Rise}{Run} = \dfrac{2}{3}}[/tex],

Thus, the slope of line EA and AC is equal.

We know in a Right Angle Triangle the side opposite to the right angle is the longest side and it is known as hypotenuse.

As already mentioned in the question " two right triangles have the line as the hypotenuse", which means line EA and line AC are already said as the hypotenuse of the triangles. therefore, the angle opposite to them is the right angle in the triangles.

1.)  

In ΔABC, the hypotenuse is the line AC, therefore, the right angle is the opposite angle which is ∠ABC.

Similarly,  In ΔEDA, the hypotenuse is the line EA, therefore, the right angle is the opposite angle which is ∠EDA.

2.)

Parallel lines are those lines that always maintain the same distance between them and will never meet. whereas, a transversal is a line that crosses two or more parallel lines. As shown in the image below,

Here, there are two pairs of parallel lines cut by a transversal

Pair I:   line ED and line AB are a pair of parallel lines, can be easily seen if both the lines are extended, while AD (or x-axis), line BC(only if extended), and line EC are the transverses between them.

Pair II:  line DA and line BC are a pair of parallel lines, can be easily seen if both the lines are extended, while AB (or y-axis), line ED(only if extended), and line EC are the transverses between them.

A family’s vacation destination is 850 miles from their home. They travel by car 6 hours on the first day of their trip. Their average speed is 45 miles per hour. The next day they travel 7 hours, averaging the same speed. How many miles are left for the family to travel?

Answers

Answer:

The distance traveled is equal to the product of the speed and the time. For the first day,

                                     d = (45 mile/h)(6 h) = 270 miles

On the second day,

                                     d = (45 mile/h)(7 h) = 315 miles

The total distance traveled after 2 days is equal to 585 miles. Subtracting this value from the given distance will give us an answer of 265 miles.  

Step-by-step explanation:

6x45=270, 7x45=315, 270+315=585, 850-585=265

265 miles left
