How many numbers between 100000 and 999999?
Answer:
there's actually 900000
Step-by-step explanation:
lets do the same thing for a smaller number to show where the previous solution went wrong if you take the interval between 255 and 0 (this is the size of one part of an ipv4 we know there is 256 bits because you have the digits 1 to 255 which makes up 255 bits and then if you ad the 0 (lower limit of the interval) you get 256-- the same principle applies here if you just do 999999-100000 you are not counting the lower limit and you are counting the upper limit which is wrong because between may be ambiguous so that it can mean including or excluding the upper and lower limit but it cannot exclude one and include the other thus making the answer 900000 including its limits and 899998 excluding them

Which pair of triangles are congruent by ASA ?
The pair of triangles that are congruent by ASA is [tex]\boxed{\bf option (d)}[/tex].
Further explanation:
Triangles are congruent when all the corresponding sides and interior angles are equal.
There are four theorems by which we say that the triangles are congruent.
1. Side-Side-Side(SSS)
If all the three sides of a triangle are equal to the corresponding sides of the other triangle, then the two triangles are congruent by SSS theorem.
2. Angle-Side-Angle(ASA)
If any two angles and the included side between the angles of one triangle are equal to the corresponding two angles and the included side between the angles of the second triangle then the two triangles are congruent by ASA theorem.
3. Side-Angle-Side(SAS)
If any two sides and angle between the sides of one triangle are equal to the corresponding two sides and angle between the sides of the second triangle then the two triangles are congruent by SAS theorem.
4. Hypotenuse Leg (HL)
If the hypotenuse and side of a right angled triangle is equal to the hypotenuse and a side of the other right angled triangle then the triangles are congruent by HL theorem.
Option (a)
The first figure shows one side is included between the two angles but the second figure shows two angles and one side as shown in below attachment.
Both the figures don’t have a single property from the above mentioned properties.
Therefore, option (a) is incorrect.
Option (b)
The first figure shows one angle between the two sides and the second figure also shows one angle between the two sides as shown in below attachment.
Both have the same property.
Therefore, the triangles are congruent by SAS rule not by ASA.
Thus, option (b) is incorrect.
Option (c)
The first figure shows one angle between the two sides and the second figure also shows one angle between the two sides as shown in below attachment.
Both have the same property.
Therefore, the triangles are congruent by SAS rule not by ASA rule.
Thus, option (c) is incorrect.
Option (d)
The first figure shows two angles and one side is included between them and the second figure shows two angles and one side is included between them as shown in below attachment.
Both have the same property.
Therefore, the triangles are congruent by ASA rule.
Thus, option (d) is correct.
Hence, the [tex]\boxed{\bf option (d)}[/tex] is correct as the triangles are congruent by ASA rule.

The pair of triangles that are congruent by the Angle-Side-Angle Congruent Theorem (ASA) are the pairs that have two corresponding angles and an included side that are congruent to each other which is: Option D.
Recall:
The Angle-Side-Angle Congruent Theorem (ASA) states that two triangles are considered congruent if they have two corresponding angles that are congruent and an included side that are congruent to each other.
The included side is the side that is lie between the two congruent angles in each of the triangles.
Thus, form the pairs of angles given, the pair in option d has two corresponding angles and an included side that are congruent to each other in each triangle.
Therefore, the pair of triangles that are congruent by the Angle-Side-Angle Congruent Theorem (ASA) are the pairs that have two corresponding angles and an included side that are congruent to each other which is: Option D.

Angela is buying a dress that is on sale for 20% off. If the original price of the dress is $60.00, how much money is Angela saving on the dress?
Angela is Saving $12 on the dress.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Original Price of Dress = $60
Discount = 20% off
So, the Price of Dress after discount
= 60- 20% of 60
= 60- 12
= $48
Hence, Angela saving $12.

Solve the compound inequality 2x > –10 and 3x < 24
5 > x > –8
5 > x < –8
–5 < x < 8
–5 < x > 8
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
[tex]2x>-10---------------------------(1)[/tex]
and
[tex]3x<24------------------------------(2)[/tex]
From eq(1), we have
[tex]\dfrac{2x}{2}>\dfrac{-10}{2}\\\\x>-5[/tex]
From eq(2), we have
[tex]3x<24\\\\\dfrac{3x}{3}<\dfrac{24}{3}\\\\x<8[/tex]
So, compound inequality becomes
[tex]-5<x<8[/tex]
Hence, Third option is correct.
Line AB contains points A (3, −2) and B (1, 8). The slope of line AB is −5 negative 1 over 5 1 over 5 5
Answer: -5
Step-by-step explanation:
The slope of a line passing through (a,b) and (c,d) is given by :-
[tex]\text{Slope}=\dfrac{d-b}{c-a}[/tex]
Then the slope of the line AB contains points A (3, −2) and B (1, 8) will be :-
[tex]\text{Slope}=\dfrac{8-(-2)}{1-(3)}\\\\\Rightarrow\text{Slope}=\dfrac{10}{-2}-5[/tex]
Hence, the slope of the line AB contains points A (3, −2) and B (1, 8) = -5

On a tour of an old gold mine, you find a nugget containing 0.82 ounce of gold. gold is worth $1566.80 per ounce. how much is your nugget worth?
Since the gold is worth $1566.80 per ounce, then the nugget is worth $1284.776.
Worth of gold per ounce = $1566.80 per ounceAmount of gold that the nugget contains = 0.82 ounces of goldThis is a question relating to multiplication. Therefore, in order to know the worth of the nugget, we've to multiply 0.82 by $1566.80. This will be:
= 0.82 × $1566.80
= $1284.776
Therefore, the value of the nuggets is $1284.776.

What is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 2 units?
4 units
2 units
Square root of 6 units
Square root of 8 units
Answer:
square root of 8
Step-by-step explanation:
because it is 8 squared
The length of the hypotenuse of a right triangle with legs of 2 units each is the square root of 8 units.
Explanation:In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. If each of the two legs is 2 units, then the length of the hypotenuse can be found as follows:
hypotenuse2 = leg12 + leg22
hypotenuse2 = 22 + 22
hypotenuse2 = 4 + 4
hypotenuse2 = 8
Therefore, the length of the hypotenuse is the square root of 8 units.

A train leaves chicago and travels east at 60 mph. another train at the same depot leaves at the same time and travels west at 72 mph. how long before the two trains are 330 miles apart?
The two trains will be 330 miles apart after 2.5 hours.
Explanation:To find how long it takes for the two trains to be 330 miles apart, we can apply the formula for relative velocity:
Relative velocity = sum of their speeds
The first train is moving east at 60 mph, and the second train is moving west at 72 mph. So their relative velocity is 60 mph + 72 mph = 132 mph.
To find the time it takes for the trains to be 330 miles apart, we can use the formula:
Distance = speed × time
330 miles = 132 mph × time
Solving for time, we have:
Time = 330 miles / 132 mph = 2.5 hours

If you shift the quadratic parent function, f(x) = x2, right 12 units, what is the equation of the new function?
A. g(x) = (x – 12)2
B. g(x) = (x + 12)2
C. g(x) = x2 – 12
D. g(x) = x2
Answer:
A. [tex]f(x) = (x-12)^2[/tex]
Step-by-step explanation:
The parent function [tex]f(x) = x^2[/tex] can be shifted 12 units to the right by moving its vertex 12 units to the right. The parent function has a vertex at (0,0) since [tex]f(0) = 0^2=0[/tex]. It will shift to (12,0) so [tex]f(12) =(12-a)^2=0[/tex]. The only value of a which will make it 0 is 12. So the equation is [tex]f(x) = (x-12)^2[/tex]
