Answer: Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign.

0.08 os ten times great as ...
0.5 is ten times great as
Answer:
Part 1) The number is 0.008
Part 2) The number is 0.05
Step-by-step explanation:
Part 1) we have
0.08 is ten times great as ...
That means----> 10 times a number is equal to 0.08
Let
x -----> the number
To find the number divide 0,08 by ten
so
0.08=10x
x=0.08/10
x=0.008
Part 2) we have
0.5 is ten times great as...
That means----> 10 times a number is equal to 0.5
Let
x -----> the number
To find the number divide 0,5 by ten
so
0.5=10x
x=0.5/10
x=0.05

A game's parking costs $18 per vehicle and a ticket for the game is $33. If your family gave you $200 for your birthday and the use of the minivan, how many friends (including yourself) can go to the game?
Answer:
you and 4 other people can go to the game
Step-by-step explanation:
18 for parking
33 for you
33 for 4 other people
= 184 and you cant add another 33 to it cause it will go over 200
Answer:
5
Step-by-step explanation:
A game's packing cost is $18
A ticket for the game is $33
Your family gave you $200 + minivan
Let's say the number of friends (including yourself) you go with to the game is f.
Equating this expression;
$18 + $33f ≤ $200
$33f ≤ $200 - $18
$33f ≤ $182
f ≤ [tex]\frac{182}{33}[/tex]
f ≤ 5.515151515
Since we cannot have 0.515151515 friends, the number of friends (including yourself attending the game must be 5).

Arun scores 36 marks in English 44 marks in Hindi and 75 marks in maths and X in Science if average score is 50 find the value of x
Answer:
x = 45
Step-by-step explanation:
The average is calculated as
average = [tex]\frac{score}{count}[/tex]
here the average = 50 , thus
[tex]\frac{36+44+75+x}{4}[/tex] = 50
Multiply both sides by 4
36 + 44 + 75 + x = 200
155 + x = 200 ( subtract 155 from both sides )
x = 45
Solve 25x^2-30=0
Round the answer to the nearest hundredth
x=-1.10 and x=1.10
x=-26.15 and x=1.15
x=0
x=-0.83 and x=0.83
Answer:
x = - 1.10 and x = 1.10
Step-by-step explanation:
Given
25x² - 30 = 0 ( add 30 to both sides )
25x² = 30 ( divide both sides by 25 )
x² = [tex]\frac{30}{25}[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{30}{25} }[/tex]
x = - 1.10 and x = 1.10 ( to the nearest hundredth )
The correct answer is a. x = -1.10 and x = 1.10 .
To solve the quadratic equation [tex]\( 25x^2 - 30 = 0 \)[/tex], we first add 30 to both sides of the equation to isolate the quadratic term:
[tex]\[ 25x^2 = 30 \][/tex]
Next, we divide both sides by 25 to solve for [tex]\( x^2 \)[/tex]:
[tex]\[ x^2 = \frac{30}{25} \] \[ x^2 = 1.2 \][/tex]
Now, we take the square root of both sides to solve for x. Remember that when taking the square root of a number, we must consider both the positive and negative square roots:
[tex]\[ x = \pm\sqrt{1.2} \][/tex]
Using a calculator, we find the square root of 1.2 and round to the nearest hundredth:
[tex]\[ x = \pm1.095445115... \][/tex]
Rounded to the nearest hundredth, the solutions are:
[tex]\[ x = -1.10 \] \[ x = 1.10 \][/tex]
Therefore, the correct options are x = -1.10 and x = 1.10 . The other options provided [tex](\( x = -26.15 \)[/tex] and x = 1.15 , x = 0 , x = -0.83 and x = 0.83 are incorrect and do not satisfy the original equation.
The complete question is- Solve [tex]25x^2-30=0[/tex]

Consider the cubic function f(x) = x^3 + ax^2 + bx + 4 where (a) and (b) are constants. When f(x) is divided by x-3, the remainder is 10. When f (x) is divided by x+1, the remainder is 6.
Show that a = -1 and b = -4
Answer:
see explanation
Step-by-step explanation:
Using the Remainder theorem
If f(x) is divided by (x - h) then f(h) = remainder, thus
f(3) = 3³ + a(3)² + b(3) + 4 = 10, that is
27 + 9a + 3b + 4 = 10
9a + 3b + 31 = 10 ( subtract 31 from both sides )
9a + 3b = - 21 → (1)
f(- 1) = (- 1)³ + a(- 1)² + b(- 1) + 4 = 6, that is
- 1 + a - b + 4 = 6
a - b + 3 = 6 ( subtract 3 from both sides )
a - b = 3 → (2)
Rearrange (2) expressing a in terms of b
a = 3 + b → (3)
Substitute a = 3 + b into (1)
9(3 + b) + 3b = - 21 ← distribute and simplify left side
27 + 9b + 3b = - 21
12b + 27 = - 21 ( subtract 27 from both sides )
12b = - 48 ( divide both sides by 12 )
b = - 4
Substitute b = - 4 into (3)
a = 3 - 4 = - 1
Hence a = - 1 and b = - 4

What is the first step in which the student made an error
Final answer:
To identify where an error might have occurred, students should be aware of common mistakes, review personal feedback, and reflect on their thought processes. This helps in understanding and correcting errors, leading to improvement in critical and reflective thinking.
Explanation:
The first step in identifying an error in a student's work is to be cognizant of common mistakes that students make. By reviewing a common errors list and reflecting upon feedback from instructors, a student can pinpoint problem areas in his or her academic practice. Starting with the prediction and diagnosis of one's own learning process is essential. This may include recognizing patterns in mistakes, understanding why an error was made, or consulting with a teacher for further clarification. Once the source of the error is identified, the student can work on corrective measures to avoid similar issues in the future. Frequently, errors in thinking or application are not due to a lack of intelligence, but rather to the way our minds are wired, leading to characteristic mistakes that can be anticipated and mitigated with practice and reflection.

Write the equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right.
a) g(x) = x + 3
b) g(x) = x + 8
c) g(x) = x − 8
d_ g(x) = x + 2
Answer:
[tex]g(x) = x + 2[/tex]
Step-by-step explanation:
Parent function [tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
If f(x) is shifted 'a' units to the right then f(x) becomes f(x-a)
If f(x) is shifted 'a' units to the left then f(x) becomes f(x+a)
[tex]f(x) = x + 5[/tex], is shifted 3 units to the right.
Then we subtract 3 from x
So , [tex]f(x) = x + 5[/tex] becomes [tex]f(x-3) = x-3 + 5=x+2[/tex]
[tex]g(x) = x + 2[/tex]
The equation of function will be;
g (x) = x + 2
Option d is true.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
Parent function, f(x) = x + 5 is shifted 3 units to the right.
Since, If a function f(x) is shifted 'a' units to the right then function f(x) becomes f(x-a).
So, The equation of function will be calculated as;
The parent function is shifted 3 units to the right.
Then, we subtract 3 as;
g (x) = x + 5 - 3
g (x) = x + 2
Thus, The equation of function will be;
g (x) = x + 2

5.241 divided by 3 please help me
The required, 5.241 divided by 3 equals approximately 1.747.
To divide 5.241 by 3, we can perform the division as follows:
1.747
------------
3 | 5.241
To start, we divide the whole number part, 5, by 3. The result is 1, which becomes the whole number part of the quotient.
Next, we bring down the decimal point and consider the decimal part of the dividend, which is 0.241. We can continue the division process by adding a decimal point to the quotient and placing a 0 to the right of the decimal point.
1.747
3 | 5.241
- 3
-----
24
Now, we divide 24 by 3, which gives us 8. We bring down the next decimal digit, which is 1, and continue the division:
1.747
3 | 5.241
- 3
-----
24
- 24
-----
1
Since there are no more decimal digits to bring down, we have finished the division. The final quotient is 1.747, rounded to three decimal places.

A manufacturing company produced 1,800 vehicle.of those 30% were trucks 25% were sports cars, and 10% were vans. How many of the vehicle were not trucks,sports cars, or vans ?
Answer:
630
Step-by-step explanation:
if you add the percentages of the trucks, sport cars and vans you get:
30% + 25% + 10% = 65%. So to find the percentage of vehicles that aren't in this categories you substract this percentage from 100%.
100% - 65% = 35%
This means that 35% of the vehicles aren't in those categories, so to find the amount you just multiply the total of vehicles with the percentage an then divide by 100
(1,800*35)/100 = 630 vehicles
