Answer:

  Positive

Step-by-step explanation:

If thinking in the abstract doesn't work well for you, choose a couple of values that match the description:

  a > 0, choose a = 1

  b < 0, choose b = -1

Now, the product is ...

  -4ab = (-4)(1)(-1) = 4 . . . a positive product

__

The product will be positive when the total number of minus signs of the factors is even. Here, there are 2 minus signs, so the product is positive.

Step-by-step explanation:

hello,

from this question, it has been stated that the lucky number is 1

from all of these values below we are to account how many times 1 appeared in these numbers have

89064, 27308, 64568 ,14121, 98226, 65388, 58732, 85801, 69902, 78431, 10380, 42006.

the total number of 1 is 6

= 6 x 1 divided by the number of trials 60

= 6 x 1/60

= 0.1

to get the proportion, we multiply 0.1 by 100

0.1 x 100

= 10%

Option 1)

6a + 8s = 102

14a + 4s = 150

each adult ticket costs 9 dollars

===================================================

Explanation:

6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102

14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150

The system of equations is

[tex]\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}[/tex]

If we multiply both sides of the second equation by -2, we get this updated system

[tex]\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}[/tex]

Add the equations straight down

6a+(-28a) = -22a

8s+(-8s) = 0s = 0 ... the 's' terms go away

102+(-300) = -198

So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.

Each adult ticket costs $9

If you want the value of s, then

6a+8s = 102

6(9)+8s = 102

54 + 8s = 102

8s = 102-54

8s = 48

s = 48/8

s = 6

Meaning each student ticket costs $6

Or you could use the other equation

14a+4s = 150

14(9)+4s = 150

126+4s = 150

4s = 150-126

4s = 24

s = 24/4

s = 6

We get the same value of s

Answer:

Step-by-step explanation:

Given the results of #5 are ...

  ∠GEF = 120, 150, 155, 135

  ∠FEM = 60, 30, 25, 45

  ∠MEH = 120, 150, 155, 135

  ∠HEG = 60, 30, 25, 45

(a) We can see that vertical angles are congruent.

(b) Each of a pair of vertical angles is supplementary to the same angle.

  ∠GEF and ∠MEH are both supplementary to ∠FEM and to ∠HEG

Answer:

x = -2 13/15

Step-by-step explanation:

-5(3x+8)-5=-2

start by multiplying out the 5 to the numbers in the parenthesis.

= -15x-40-5=-2

subtract 5 from -40

=15x-45=-2

add the 45 to itself to get rid of it and add it to -2

=15x=43

divide 43 by 15

=2.8666666666 or -2 13/15

Answer:

y = 3x + 2

Step-by-step explanation:

First you want to know what the slope intercept form is. y = mx + b. Now take two points from the table and put them in the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] and get the slope of 3. Now we have y = 3x + b. To find b we need to plug in any point into the equation. I chose (-1, -1). -1 = 3(-1). Solve and you get 2. Now we are left with y = 3x + 2

The equation of the line is given by: [tex]y = 3x + 2[/tex]

----------------------------

The equation of a line, in slope-intercept formula, has the following format:

[tex]y = mx + b[/tex]

In which

----------------------------

[tex]m = \frac{11 - (-1)}{3 - (-1)} = \frac{12}{4} = 3[/tex]

Then

[tex]y = 3x + b[/tex]

----------------------------

Point (-1,-1) means that when [tex]x = -1, y = -1[/tex], and we use this to find b.

[tex]y = 3x + b[/tex]

[tex]-1 = 3(-1) + b[/tex]

[tex]b = -1 + 3 = 2[/tex]

Thus

[tex]y = 3x + 2[/tex]

Answer:

1/2 mile/1/5 hour = 5/2 mph = 2 1/2 mph

Step-by-step explanation:

Answer:

0.80mph

Step-by-step explanation:

If 1/5 = 1/4, then:

she swims 1/5 miles for every 1/4 (fourth) of an hour

per hour means 1 hour

we must covert 1/4 to 4/4 (one mile)

1/4 × 4/1 = 4/4

if we multiply by 4/1 to get to 4/4, then we must also multiply by 4/1 for 1/5 miles

1/5 × 4/1 = 4/5

Her unit rate in miles per hour is 4/5 per 1 miles, or 0.80mph

*0.80 = 4/5 because 4 × 20 = 80 and 5 × 20 = 100; 80/100 = 0.80*

15,077,500  

Area= W * H

In this case area would be 1850 * 8150 which equals 15,077,500

The number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here, (a) is the numerator and (b) is the denominator.

We have to find the addition of two fraction number 1/2 and 1/3. Suppose the value which is closest to 1/2 + 1/3 is n. Thus,

[tex]n=\dfrac{1}{2}+\dfrac{1}{3}\\[/tex]

Cross multiply to find the addition of two numbers,

[tex]n=\dfrac{3+2}{6}\\n=\dfrac{5}{6}\\n=0.833[/tex]

Thus, the number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.

The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.

The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:

A = s²

36 sq. units = s²

√(36 sq. units) = √s²

6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)

Therefore, ...

P = 4s

P = 4(6 units)

P = 24 units is the perimeter of a square whose area is 36 square units
