Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.
Step-by-step explanation:
The quotient of two integers with different signs is negative because if a number is divided by the negative number it always gives a negative value.
What is the quotient?The number being divided is referred to as the dividend, and the number being divided by it is referred to as the divisor. The quotient is the outcome of the division.
Due to the following causes, it is discovered that the two quotients with the two different signs give a negative quotient.
Divide the absolute values of the integers to divide the two numbers with a different sign. The ratio is adverse. Note from this rule that 12/–3 and −12/3 are equal to – 4.
The product of two negative integers has a positive quotient. If the indicators differ, the response is unfavorable. The answer is yes if the signals are consistent.
Thus, the quotient of two integers with different signs is negative because if a number is divided by the negative number it always gives a negative value.

Cristian says that when you raise a base number to a power of 3, it is impossible for the number to get smaller. Do you agree or disagree? Justify (prove) your answer.
Answer: I disagree
Step-by-step explanation:
I disagree with the statement from Cristian. When you raise a base number to a power of 3, it is possible for the number to get smaller.
For example, let's say our base number is negative 2, that is -2. Now let's find the cube of the number. This will be:
= -2^3 = -2 × -2 × -2 = -8
In this example, we can see that -8 is smaller than -2. This shows that the statement by Cristian is not correct.

If the population of Hillsborough County was 1.3 million in 2015 and the projected annual growth rate of the population is 3%, what would the projected population of the county be in 25 years? Round to the nearest hundredth.
Answer:
2,721,911.31
Step-by-step explanation:
The formula for Population growth rate is given as:
P(t) = Po(1 + r)^t
Where
Po = Initial population = 1,300000
P(t) = Population after t years
r = growth rate = 3%
t = time in years = 25
Hence,
P(25) = 1,300,000(1 + 0.03)^25
P(25) = 2,721,911.3086
P(25) Approximately = 2,721,911.31
The projected population of the county be in 25 years is 2,721,911.31

The choices which are not triangle congruence postulate are: 3)Angle Side Side
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
The reflexive property of congruence states that the considered geometric quantity, whether it be angle, line segment, or shape etc, is congruent to itself.
We need to find the choices which are not triangle congruence postulate or theorem.
The postulates that are used to prove the triangles congruent are,
1)Side Side Side
2)Side Angle Side
3)Angle side Angle
4)Angle Angle Side
5)Hypotenuse Leg

Carter works in a department store selling clothing. He makes a guaranteed salary of $400 per week, but is paid a commision on top of his base salary equal to 25% of his total sales for the week. How much would Carter make in a week in which he made $1750 in sales? How much would Carter make in a week if he made xx dollars in sales?
Answer:
$837.5
Step-by-step explanation:
Step one:
given data
He makes a guaranteed salary of $400 per week
Commision on top of his base salary equal to 25% of his total sales for the week
Required
His total salary when he made sales of 25%
Step two
let us solve for 25% of $1750 made
=25/100*$1750
=0.25*$1750
=$437.5
Hence his total payment for the week will be
=$400+$437.5
=$837.5
Also, if the sales is $x his pay would be
let y be his pay

Answer:
(b) 48
Step-by-step explanation:
In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.
x = √(36·64) = √36×√64 = 6×8
x = 48

All of the triangles are similar, so the ratios of corresponding sides are the same.
short side/long side = x/64 = 36/x

To find:
The value of given expression when x=5.
Solution:
We have,

[tex]=100+(-13)[/tex]
[tex]=100-13[/tex]

Find the error and explain why its wrong
Answer:
The last part.
Step-by-step explanation:
The error is only at the last part. Basically the answer part.
The answer should be —
[tex]13 \sqrt{5} [/tex]
We don't multiply the square roots when adding or subtracting. That'd contradict the rules.
Here, we let the square root of five as x-term.
[tex] \sqrt{5} = x[/tex]
[tex]4 \sqrt{5} + 9 \sqrt{5} = 4x + 9x[/tex]
As we add up, we would get 13x. Thrn we convert x-term back to square root of five.
The answer would be —
[tex]13x \\ x = \sqrt{5} \\ 13 \sqrt{5} [/tex]
Remember that we don't multiply the square roots when adding or subtracting.

Answer:
$88
Step-by-step explanation:
first, you find 20% of 57 which = 11.4
then subract it with 57 which looks like 57-11.4 = 45.6
= 45.6
first, you find 20% of 53 which = 10.6
then subract it with 53 which looks like 53-10.6 = 42.7
= 42.4
then you add them both which = 45.6+ 42.4= 88

Answer:
1) 8x^2-10x-7
2) 30[tex]x^{9\\}[/tex]- 60[tex]x^{5}[/tex]
3) -10y^6 - 45y^5 + 25y^4
4) 30x^9 - 60x^5
5) 30x^9 - 60x^5
Step-by-step explanation:
1) (2x+1)(4x-7), we will multiply each term from the first parenthesis against every term in the second.
2x*4x = 8[tex]x^{2}[/tex], 2x*-7 = -14x
1(4x-7) = 4x-7.
8x^2-14x+4x-7 = 8x^2-10x-7
2) 10[tex]x^{5}[/tex](3x^4-6)
10x^5(3x^4) = 30x^9
10x^5(-6) = -60x^5
30[tex]x^{9\\}[/tex]-60[tex]x^{5}[/tex]
3) -5y^4(2y^2+9y-5)
-5y^4(2y^2) = -10y^6
-5y^4(9y) = -45y^5
-5y^4(-5) = 25y^4
-10y^6 - 45y^5 + 25y^4
4) 10x^5(3x^4 - 6)
10x^5(3x^4) = 30x^9
10x^5(-6) = -60x^5
30x^9 - 60x^5
5) (3y - 5z)(8y - 3z) =
3y*8y = 24y^2
3y*(-3z) = -9yz
-5z(8y) = -40yz
-5z(-3z) = 15z^2
24y^2 + 15z^2 - 49yz
The discount on a pair of socks is 15%. The socks are on sale for $17. What was the original price of the socks?
Answer:
$19.55
Step-by-step explanation:
17*0.15=2.55
17+2.55=19.55
Answer:
$20
Step-by-step explanation:
The original price is p.
Now, a discount of 15% is = 100%-15% = 85% of the original price.
0.85p = 17
p = 17/0.85
p = 20
