Use the number line to represent all the solutions to the inequality -3(2j-11)>=8j-9.
Select a ray. Move the point on the ray to the correct place on the number line.

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

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.

The height of the flagpole is 46 feet

Step-by-step explanation:

First we find the ratio to connect the variables

Tan(∅) = opposite/adjacent

Plug in the Variables

Tan(39) = x/50

Solve for x

50*tan(39) = x

x = 40.48

Don't forget to include the man's height

40.48 + 6 = 46.48

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

Step-by-step explanation:

Answer:

k=-9±2√15

Step-by-step explanation:

For the above quadratic to have equal roots then it's discriminant b²-4ac must equal 0

By comparing x²+(k+9)x+15=0 with ax²+bx+c=0,a=1,b=k+9 and c=15

(k+9)²-4(1×15)=0

k²+18k+81-60=0

k²+18k+21=0(factorize)

k=-9±2√15

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.

Probability that the student drinks soda or coffee regularly is 60%

Option D is correct

Percentage of students that drink soda regularly, P(s) = 40%

Percentage of the students that drink coffee regularly, P(c) = 30%

Percentage of students that drink both coffee and soda regularly,

P(s and c) = 10%

Percentage of students that drink coffee or soda regularly is:

P(s or c) = P(s)  +  P(c) - P(s and c)

P(s or c) = 40  +  30 - 10

P(s or c) = 70 - 10

P(s or c) = 60

Probability that the student drinks soda or coffee regularly is 60%

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)
