Piyra's class has adopted two equal sections of a highway to keep clean.The combined length is 3/4 of a mile.How long is each section,please help me out​

Answer:

[tex]x=\dfrac{-(-15)\pm\sqrt{(-15)^2-4(-2)(-3)} }{2(-2)}[/tex]

Step-by-step explanation:

Given equation:  [tex]-2x^2 - 11x + 7 = 10 + 4x[/tex]

First, rearrange the equation so that it is in the general form of [tex]ax^2+bx+c=0[/tex]

[tex]-2x^2 - 11x + 7 = 10 + 4x[/tex]

Subtract 4x from both sides:

[tex]-2x^2 - 15x + 7 = 10[/tex]

Subtract 10 from both sides:

[tex]-2x^2 - 15x - 3 = 0[/tex]

Therefore,

Input these values into the quadratic formula:

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

Therefore,

[tex]x=\dfrac{-(-15)\pm\sqrt{(-15)^2-4(-2)(-3)} }{2(-2)}[/tex]

Answer:

[tex]\frac{28}{3}[/tex]    

Step-by-step explanation:

When dividing fractions, we must always remember a very important step:

we can multiply the two fractions instead of divide as long as the second fraction must be flipped opposite as a reciprocal.

Let me explain:

When given a simple problem like [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{2}{3}[/tex] , we flip the second fraction (called reciprocal) and multiply it together instead.

[tex]\frac{1}{2} * \frac{3}{2}[/tex]

There, we can just multiply the numerators with each other and the denominators as each other.

1x3=3

2x2=4

Therefore, the answer will be [tex]\frac{3}{4}[/tex].

Similar in this case, we must flip the second fraction and pretend we never even saw a division sign (because who likes dividing anyways?)

[tex]\frac{35}{5}[/tex] ÷ [tex]\frac{-3}{4}[/tex]            flip and multiply reciprocal

[tex]\frac{35}{5} * \frac{-4}{3}[/tex]            

[tex]\frac{140}{15}[/tex]                  simplify

[tex]\frac{28}{3}[/tex]                   final answer!

Hello.

In order to find the slope of the given line, we should use the slope formula:

[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1}}[/tex]

y₂= the y-coordinate of the second point (6

y₁= the y-coordinate of the first point (-14)

x₂=the x-coordinate of the second point (-10)

x₁=the x-coordinate of the first point (-4)

Let's plug in the values and solve:

[tex]\mathrm{\displaystyle\frac{6-(-14)}{-10-(-4)}=\frac{6+14}{-10+4} =\frac{20}{-6} =-\frac{20}{6} =-\frac{10}{3} }[/tex]

Answer:

[tex]\Large\boxed{\sf{\displaystyle-\frac{10}{3} }}[/tex]

I hope it helps.

Step-by-step explanation:

Given that:

Number of name tags = 10

Number of pens = 18

to distribute evenly among the name tag stations with none left over ; we need to obtain the greatest common factors of both 10 and 18 to know the number of stations Derek can set up ;

Factors of :

10 : 1, 2, 5, 10

18 : 1, 2, 3, 6, 9, 18

The greatest common factor is 2.

Hence, Derek can setup 2 stations.

Step-by-step explanation:

The speed of the ball would be 13 m/s just before it strikes the ground.

A ball is thrown horizontally from the top of a 110 m high building. 61 meters horizontally from the moment of release, the ball falls on the earth.

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

First of all, we get the time of aviation from the vertical component:

Here s = 110 m and g = 9.8 m/s²

s = 1/2 × gt²

Solve for t

t = √(2s/g)

Substitute the values of s = 110 m and g = 9.8 m/s² in the equation,

t = √(2×110/9.8)

t = √22.44

t = 4.7 sec

The horizontal component of velocity is constant :

v = s/t

Here s = 61 m and t = 4.7 sec

v = 61/4.7

v = 12.97 ≈ 13

Therefore, the speed of the ball would be 13 m/s just before it strikes the ground.

Answer:

Third option: (0, 7)

Step-by-step explanation:

A reflection can be thought of as folding or "flipping" an object over the line of reflection.

• The original object is called the pre-image, and the reflection is called the image.

• The image is usually labeled using a prime symbol, such as A'B'C'.

• An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, with right and left reversed.

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).

Label the points for the pre image:

Pre image

Point A: (0, -2)

Point B: (3, -7)

Point C: (0, -7)

And now we change the y-coordinates in the points into their opposites:

When reflected over the x-axis:

Ponit A (0, -2) changes to A' (0, 2)

Point B (3, -7) changes to B' (3, 7)

Point C (0, -7) changes to C' (0, 7)

New image:

A' (0, 2)

B' (3, 7)

C' (0, 7)

So the new image for vertex C, would be:

Third option: (0, 7)

Look at the both of the graphs:

Answer:

B. $0.27

Step-by-step explanation:

300 centimeters is 3 meters

So, no we just multiply the number of meters by the price (0.09)

0.09 X 3 = 0.27

So, the answer is B, $0.27

300 cm of streamers

0.09 per m

1 m= 100 cm

the price in dollars of 300 centimeters of streamers.

[tex]300cm = 3m[/tex]

[tex]price = 3 \times 0.09[/tex]

[tex] = 0.27[/tex]

therefore, the price of 300 cm of streamers is $0.27.

Scatter plot attached below.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

The scatter plot for the correlation between x and y closest to −1 is attached below.

The whole angle = the sum of the parts

80 = 43 + x

x = 80 - 43

The  equation that can be used to find the height of the rectangles when the width is known is h = P - 4

perimeter of rectangle = 2(l + h)

P(l, h) = 2(l + h)

Since the perimeter = 2(4+5) = 18, then;

18 = 2(4 + h)

9 = 4 + h

h = 9 - 4

h = P - 4

Hence the  equation that can be used to find the height of the rectangles when the width is known is h = P - 4
