The difference of the weight is 1 kg 949 g.
How to find the difference of numbers?The weight of the two items to find the difference are as follows:
25 kg 32 g23 kg 83 gDifference in mathematics is the result of subtracting one number from another.
Therefore, let's convert the weight .
1000g = 1 kg
32 g =
cross multiply
weight = 32 / 1000
weight = 0.032 kg
1000g = 1 kg
83 g = ?
cross multiply
weight = 83 / 1000 = 0.083 kg
Therefore,
25 kg + 0.032 kg = 25.032 kg
23kg + 0.083 kg = 23.083 kg
Hence,
the difference of the weight = 25.032 kg - 23.083 kg
the difference of the weight = 1.949 kg
Hence,
the difference of the weight = 1 kg 949 g

Use the discriminant to determine the number of real solutions to the quadratic equation.
70w2 - 12w + 1 = 0
What is the number of real solutions?
Answer:
There are two real and different roots
Step-by-step explanation:
The discriminant is given by b²-4ac
(-12)²-4(70×1)
144-280
136
Now 136>0
Let D = discrimination
Rules:
If D > 0, there are 2 real number solutions.
If D = 0, there is only 1 real number solution.
If D < 0, there are 2 imaginary solution.
Given 70w2 - 12w + 1 = 0, b = -12, a = 70 and c = 1.
D = b^2 - 4ac
D = (-12)^2 - 4(70)(1)
D = 144 - 280
D = -136
Our D value is less than 0.
Our case is D < 0.
This means the given quadratic equation has 2 imaginary solutions.

How do I substract 7/10 minus 3/15
Answer: 0.5
Step-by-step explanation:
To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.
Fraction: 7/10 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
7 is a prime number;
10 = 2 × 5;
gcf (7; 2 × 5) = 1;
Answer:
First you have to find the common denominator
Next you take what you did to the bottom you gotta do to the top like if you 30 does into both them you multiple 3 times 2 cause you did that to 15 and multiply 7 times 3
Then you subtract

Tara is selling magazines for her school’s fundraiser. She wants to sell at least $360 in sales. Each magazine costs $4.50 and Tara has already sold $112.50 in sales. Which inequality below would represent this situation.
Answer:
1. Given gross salary is = $768
Federal tax withholding = $68
Social security = 6.2% or 0.062*765 = $47.43
Medicare tax = 1.45% or 0.0145*765 = $11.09
State tax = 22% or 0.22*68 = $14.96
Now net salary = gross salary - tax deductions
= $623.52 (option D)
2. = 17.13% (option D)
3. Option B.II and III

Substitute: f(x) + g(x) = 5x² - 3x - 1 + 2x² - x + 3Combine like terms (x²): f(x) + g(x) = 7x² - 3x - 1 - x + 3Combine like terms (x): f(x) + g(x) = 7x² - 4x - 1 + 3Combine like terms (Z): f(x) + g(x) = 7x² - 4x + 2Which number sentence matches a model with 9 balloons and 9 weights?
Which number sentence matches a model with 9 balloons and 9 weights?
9+0=99 plus 0 is equal to 9
9+(−9)=09 plus negative 9 is equal to 0
9+9=189 plus 9 is equal to 18
−9+(−9)=−18
The correct number sentence matches a model with 9 balloons and 9 weights is,
⇒ 9 + (-9) = 0
Here,
We have to find the number sentence matches a model with 9 balloons and 9 weights.
What is Mathematical expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Now,
Since, The balloons are in upward direction, so it take positive sign.
Hence, 9 balloons = +9
Since, The weight is are act in downward direction, so it take negative direction.
Hence, 9 weight = -9
Combine both we get;
9 + (-9) = 9 - 9 = 0
Therefore, The correct number sentence matches a model with 9 balloons and 9 weights is,
⇒ 9 + (-9) = 0

What would this question look like after we change the mixed number to improper & use KCF to rewrite the question?
h) 3 1/2 divided by 1/3 =
A) 7/2 x 1/3
B) 7/2 x 3/1
C) 6/2 x 1/3
D) 7x3
Hurry !!
Answer:
The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: [tex]3\frac{1}{2}\div\frac{1}{3}[/tex]
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
[tex]3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}[/tex]
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
[tex]=\frac{7}{2}\times \frac{3}{1}[/tex]
So, The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.
