Answer:

37.5 miles per hour

Step-by-step explanation:

d= rt; d is distance (225 miles), r is rate, and t is time (6 hours)

225= 6r

225/6 = 6r/6

37.5= r

37.5 miles per hour

Hope this helps!

Answer:

58 girls

44 boys

Step-by-step explanation:    

102 divided by 2= 51                              have to divide, 14 divided by 2 = 7

51 - 7= 44

51 + 7= 58

58 + 44= 102

according to my calculations hope i helped ^_^

and also 58 -44= 14 is the difference between them

Step-by-step explanation:

Kindly find attached a detailed image to better understand the solution to this problem.

given that the total length of the line is 720ft

and also the line is divided into three sections

This means that the line will also be divided into three parts

720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.

now for the other two sides

the total length of the rope is  = one length size of the rectangle+ 4 width size of the rectangle

one width size of the rope is x

then 4 width size is 4x

720=length of rectangle +4x

length of rectangle= 720-4x

area of a rectangle is =length *width

area of rectangle is =  (720-4x)*x

Hence the function A=  (720-4x)x can be used to solve for the area of the rectangle.

Answer:

-3

Step-by-step explanation:

this is because you subtract 4x from one side to get -3x +3= 12. then u get rid of the 3 so you subtract is and get -3x=9. therefore u get -3. (please don’t delete my answer when I take time out of my day to help you)

Answer:

First, the function:

y = x

Is:

Positive if x > 0

Negative if x < 0

Now, on another hand, the function y = IxI is:

Positive if x < 0

Positive if x > 0.

Then the only part that changes is the negative side of the domain, and the thing that changes is the sign (the change of sign is equivalent to a reflection over the x-axis or the line y = 0".

Then the correct option is:

"All points for x < 0 are reflected over the x-axis"

I suppose that this is option C, the missing one.

Answer:

662.6%

Step-by-step explanation:

Answer:

Yes, because lines m1 and m2 have the same slope of -2

Step-by-step explanation:

For given two lines L1 and L2 with slope m1 and m2 respectively, the condition for the two lines to be parallel is for the two equations to have the same slope. If m1 = m2, the meaning is that the line L1 and L2 are parallel to each other no matter the equation of the lines in question.

The general equation of a line is y = mx+c where;

m is the slope and c is the intercept.

Even though we are not given the equation of both lines, the base line is that for two lines to be parallel to each other, they must have the same slope.

The correct option is therefore "Yes, because lines m1 and m2 have the same slope of -2"

Answer:

cos α = - [tex]\frac{12}{13}[/tex]

Step-by-step explanation:

Since α is in second quadrant then cosα < 0

Using the identity

sin²α + cos²α = 1 then

cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]

         = - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]

         = - [tex]\sqrt{1-\frac{25}{169} }[/tex]

         = - [tex]\sqrt{\frac{144}{169} }[/tex]

         = - [tex]\frac{12}{13}[/tex]

Answer:

$15.90

Step-by-step explanation:

13 lbs × 1.20 = $15.60

15.6 + .3=15.9

Answer:

y= - 2x+3

Step-by-step explanation:

3 is our start possition

the number before the x is the rise over run

so we would "rise" (vertical) 2 but since it has a - it will be going the oppisite direction then our run would be 1 going over horizenly 1 block

Answer:

(2x+7)° + (5x+4)° + 69° = 360°

=> 2x + 7 + 5x + 4 + 69 = 360

=> 7x + 80 = 360

=> 7x = 360 – 80

=> x = 280/7

=> x = 40

Answer:

x=40

Step-by-step explanation:

(2x+7)*+(5x+4)*+69*=360*   (360* because its a circle)

7x+80=360       (combine like terms)

- 80     -80      (minus 80 both sides)

7x=280      (divide 7 both sides)

x=40

Answer:

r=−1/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(r−10)=−51

(5)(r)+(5)(−10)=−51(Distribute)

5r+−50=−51

5r−50=−51

Step 2: Add 50 to both sides.

5r−50+50=−51+50

5r=−1Step 3: Divide both sides by 5.

5r/5=−1/5

r=−1/5

Answer:

Step-by-step explanation:

5(r - 10) = -51

5r - 50 = -51

5r = -51 + 50

5r = -1

r = - ¹/₅ or 0.2
