3. Scout is conducting a research project on traffic patterns
in her town. She realizes that at 6:00 AM each morning, the
traffic lights reset and function on a pattern. The traffic light
on Main St. turns red every 7 minutes. The traffic light on Elm
St. turns red every 15 minutes. At what time will both lights be
red at the same time?

Answers

Answer 1

Answer:

7:45

Step-by-step explanation:

Since they both turn red at differnt times, you have to find a multiple to find the time they will be both on

Main St: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105

Elm St. 15, 30, 45, 60, 75, 90, 105

They will both turn on 105 minutes or 1 hour and 45 minutes from 6

6 + 1 hr 45 min = 7:45

Answers

Answer:

B

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form.  That form is usually written [tex]y=mx+b[/tex] where  m  is the slope and  b  is the y-intercept.

Solve the first equation for y.

[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

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

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts.  There is no solution to the system.

Answers

Answer:

$8.87

Step-by-step explanation:

how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22

Answers

Answer:

x = 4, y = -3

Step-by-step explanation:

{2x - y = 11

{x + 3y = -5

You can use the substitution method by solving for x in the second equation:

x + 3y = -5

Subtract 3y from both sides:

x = -3y - 5

Now, substitute this value for x into the first equation:

2x - y = 11

2(-3y - 5) - y = 11

Distribute:

-6y - 10 - y = 11

Add 10 to both sides:

-6y - y = 21

Combine like terms:

-7y = 21

Divide both sides by -7:

y = -3

Next, substitute this value for x into the second equation:

x + 3y = -5

x + 3(-3) = -5

Multiply:

x - 9 = -5

Add 9 to both sides:

x = 4

Given Angle AOC = 90,

Angle AOB + Angle BOC = 90

[tex]3x + 46 + 14 = 90 \\ 3x + 60 = 90 \\ 3x = 90 - 60 \\ 3x = 30 \\ x = 30 \div 3 \\ = 10[/tex]

Answer:

B) 10

Step-by-step explanation:

It is given that the (m<AOC) is (90) degrees. It is also given that (<AOB) and (<BOC) compose (<AOC). Therefore, the following statement can be made;

(m<AOB) + (m<BOC) = (m<AOC)

Substitute,

(3x + 46) + (14) = (90)

Simplify,

3x + 60 = 90

Inverse operations,

3x + 60 = 90

What is the value of x, the number of photos I need to print?​

Which graph represents a quadratic function with a negative discriminant?

Choice 1
Choice 2
Choice 3
Choice 4

Answers

Answer:

Choice 4

Step-by-step explanation:

#4   because the graph does not intersect the x-axis

The graph that represents a quadratic function with a negative discriminant is graph 4.

What is a Discriminant?

The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.

D = b2 - 4ac,

If the value of the discriminant is greater than zero then the roots of the equation are real and distinct,If the value of the discriminant is equal to zero then the roots of the equation are real and same, andIf the value of the discriminant is less than zero then the roots of the equation are imaginary.

Since for the value of the discriminant to be negative, the roots of the quadratic equation should be imaginary. Also, imaginary never intersects the x-axis of the graph.

Now, in the group of the graphs the only graph that does not intersect the x-axis of the graph or have imaginary roots is graph 4.

Hence, the correct option is graph4 (Bottom Right).

x = (3-2√11)/5 ; x= (3+2√11)/5

Step-by-step explanation:

Δ/4 = (b/2)^2 - ac  where b is the term that multiplies x, a is the therm that multiplies x^2 and c is the therm without x

Δ/4 = (-3)^2 - (-7*5) = 9 + 35 = 44 = 2^2 *11

x1 = (3 - √2^2 *11)/5 = (3-2√11)/5

x2 = (3+ √2^2 *11)/5 = (3+2√11)/5

What is the area of this regular polygon?

Answers

Answer:

A=25√3 cm^2

Step-by-step explanation:

Since it is a regular triangle, all sides are equal to 10cm. The dotted line is a perpendicular bisector, which means that it seperates the triangle into two perfect halves. So a right triangle is formed. The bottom of the right triangle will be half of 10, and 10/2=5. So to find the missing side, use the pythagoreom theorem.

5^2+x^2=10^2

25+x^2=100

x^2=75

x= 5√3

The height of the triangle is found, so apply the formula for area:

A=1/2*5√3*10

A=25√3
