When subtracting a negitive number from a positive number the difference ends up being a positive. The answer is 7, therefore, greater than 4.

Answer: 2 * 2 = 4

Explanation: Thanks for the points !!

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

Answer: 36

Step-by-step explanation:

Using the Pythagorean Theorem, we can determine that the length of CD is 11.62, rounded to the closest hundredth.

When the length of the longest side of a right triangle is squared, the result will be equal to the total of the squares of the lengths of the other two sides of the right triangle that are smaller.

Taking into account the following:

Side AB = 6

Side AC = 12

The perpendicular bisector theory states that AD equals half of AB, which equals half of (6), which equals three.

By using the Pythagorean theorem, we get the following:

The length of the CD is equal to (AC2 - AD2)

The length of the CD is equal to 122 minus 32.

The length of the CD equals (144 - 9)

11.62 is the length of the CD.

Consequently, by using the Pythagorean Theorem, we can determine that the length of the CD is 11.62, rounded to the closest hundredth.

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)

Answer:

c he is your answer dear friend‍♀️‍♀️

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%

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.

If A and B are independent events, then P(A and B) = P(A)*P(B)

We multiply the probabilities of each separate event to find the probability of the compound event.

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.

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)

Answer:

m<S = 80°

Step-by-step explanation:

The figure given shows a cyclic quadrilateral.

Angle S and Angle Q are opposite angles of the cyclic quadrilateral. Thus, it is known that opposite angles of a cyclic quadrilateral are supplementary. Since m<Q = 100°

Therefore:

m<S = 180° - 100°

m<S = 80°
