Step-by-step explanation:
The greatest 6 digit even numbers with 4 in the ten thousand place and all digits different
Answer:
948,762
Step-by-step explanation:
The greatest six digit number would have to start with 9. It is given that the four is in the ten thousand place. Since no number can be repeated. I put the next largest number to 9 in the thousands place which is 8. I then put 7 then 6. Since the number has to be even I put 2 since 8, 6 and 4 were already used.
The greatest 6 digit even numbers with 4 in the ten thousand place and all digits different is 948,762.
What are even numbers?An even number is an integer that can be divided by two and remain an integer or has no remainder.
Now it is given that,
greatest 6 digit even numbers with 4 in the ten thousand place and all digits different
So, the greatest will be starting from 9
Digit at the ten thousand place is fix, 4
Digit at the thousand place is 8
Digit at the hundred place is 7
Digit at the ten place is 6
Since, it is an even number then it must be divisible by 2.
So, last digit at ones is 2
Thus we get, 948,762
hence, the greatest 6 digit even numbers with 4 in the ten thousand place and all digits different is 948,762.

Step-by-step explanation:
Additive inverse are numbers with the same number but different signs. For example, 1 and -1 are additive inverse.
An additive inverse and it original number add to zero.
For example,
[tex]1 + ( - 1) = 0[/tex]
Using this info, w is -0.8
0.8 and -0.8 are equidistant from 0.
-0.8 is 2 mark to the right of -1.
So this means that 0.8 is 2 mark to left of 1.

prince covers 1200 meter distance in 10 minutes . calculate his velocity
Answer: 120 m/min or 2 m/s
Concept:
Here, we need to know how to calculate velocity.
Velocity = ΔD / ΔT
The SI unit of velocity is m/s
Solve:
Given information
Distance = 1200 m
Time = 10 min
Given expression
Velocity = ΔD / ΔT
Substitute values into the expression
Velocity = 1200 / 10
Velocity = 120 m/min
Extra:
**Disclaimer** Ignore this part if it is irrelevant to what you are learning.
If the question needs an answer with SI unit, then please see below:
Given information
Distance = 1200 m
Time = 10 min = 10 × 60 = 600 sec
Given expression
Velocity = ΔD / ΔT
Substitute values into the expression
Velocity = 1200 / 600
Velocity = 2 m/s

Gross income is:
A. the amount of pay after tax and benefit deductions.
B. the amount of pay after tax but before benefit deductions.
C. the total amount of earned salary or wages.
D. the total amount an employer withholds for taxes.
Gross income is: The total amount of earned salary or wages. Option C is the correct answer.
Gross income refers to the total amount of money earned by an individual before any deductions or taxes are taken out. It represents the complete earnings from employment or other sources of income before any adjustments or deductions are made.
Gross income includes the full amount of salary or wages earned by an individual, as well as any additional income such as bonuses, commissions, or tips.
Option A is incorrect because gross income is the total amount earned before tax and benefit deductions are applied.
Option B is incorrect because gross income is not after tax, but rather before any tax deductions.
Option D is incorrect because gross income does not specifically refer to the amount withheld for taxes, but rather the total amount earned before any deductions.

Which number produces a rational number when added to 1/2?
A. 4.35889894...
B. 0.314
C. 12
D. TT
Answer:
B and C
Step-by-step explanation:
A is a non terminating number which means it isn't rational. B and C are both rational and adding 1/2 to them won't change that, since they are terminating numbers. D is not a number.
Answer:
12+1/2 (0.5 as a decimal)
Step-by-step explanation:
π +0.5 will give an irrational number.
0.314 is rational
12 is a counting number.

can anyone explain the steps for how to solve it too? i’m confused :(
Answer:
1936
Step-by-step
[tex][15 - (1 - 6 + 21 + \sqrt{9} )] ^{2}[/tex]
use BIDMAS
(1 - 6 + 21 + [tex]\sqrt{9}[/tex]) = (1 - 6 + 21 + 3) = (1 - 30) = -29
[15 - -29] = [15 + 29] because two minuses together make a plus
[tex]44^{2}[/tex] = 1936
a system of equations is given below in terms of the scalar parameters a and b.
ax + 2y+ 4z = b
2x +y+3z= a+1
5x-2y+ (a+1)z= 3
(1) Show that if a = -5 or a=2, the system does not have a unique solution.
A system of equations only has a unique solution if all the equations are linearly independent (this means that we have two or more equations representing the same curve).
Here we have the system:
a*x + 2*y + 4*z = b
2*x + y + 3*z = a + 1
5*x - 2*y + (a + 1)*z = 3
Now we want to show that if a = -5 or a = 2, then the system does not have a unique solution.
To see this, we can just replace a by these values and see that the equations are not linearly independent.
for a = 2 we get:
2*x + 2*y + 4*z = b
2*x + y + 3*z = 2 + 1
5*x - 2*y + (2 + 1)*z = 3
Simplifying this:
2*x + 2*y + 4*z = b
2*x + y + 3*z = 3
5*x - 2*y + 3*z = 3
From the second and third equation we can write:
2*x + y + 3*z = 3 = 5*x - 2*y + 3*z
2*x + y + 3*z = 5*x - 2*y + 3*z
2*x + y = 5*x - 2*y
3*y = 3*x
y = x
now that we know this, we can rewrite the equations as:
4*(x + z) = b
3*(x + z) = 3
Now we can take the quotient of the two equations to get:
(4*(x + z))/3*(x + z) = (4/3) = b/3
b = 4
Then the equations become:
4*(x + z) = 4
3*(x + z) = 3
Here we can divide te above one by 4 and the below one by 3 to get:
(x + z) = 1
(x + z) = 1
So both equations represent the same line, thus, the system does not have a unique solution.
Now for a = -5:
-5*x + 2*y + 4*z = b
2*x + y + 3*z = -5 + 1
5*x - 2*y + (-5 + 1)*z = 3
Simplify it:
-5*x + 2*y + 4*z = b
2*x + y + 3*z = -4
5*x - 2*y - 4*z = 3
Now we can rewrite the first equation as:
-5*x +2*y - b = -4*z
and the third one as:
-4*z = 3 - 5*x + 2*y
Then we can write:
-5*x +2*y - b = -4*z = 3 - 5*x + 2*y
-5*x +2*y - b = 3 - 5*x + 2*y
Now we can remove the -5*x in both sides to get:
+2*y - b = 3 + 2*y
Now we can remove the 2*y in both sides to get:
-b = 3
b = -3
Replacing this in our system we get:
-5*x + 2*y + 4*z = -3
2*x + y + 3*z = -4
5*x - 2*y -4*z = 3
Now we can multiply the first equation by -1:
-1*(-5*x + 2*y + 4*z)= -1*(-3)
5*x - 2*y - 4*z = 3
This is the same as the third equation, so here we can see that the first and third equations represent the same line, thus, the system of equations does not have a unique solution.
