Answer:

16.4

Step-by-step explanation:

so , since this question stated there ARE coaches but does NOT say how many exactly , that's what you have to find out , so each coach can take 50 people each and there are 820 in total so you have to divide 820 by 5 and you get 16.4 . that means there must be 16.4 coaches to go but you cant split the coach into a 4th you have to round down (because the decimal is lower than 5 ) so then you'll get 16 coaches as your final answer

17 coaches are needed.

Given each coach can take 50 peoples to festivals and there are 820 people in total.

We have to calculate the no. of coaches.

Now no. of coaches is total no. of peoples divided by 50.

So, Coaches needed = [tex]\frac{820}{50}[/tex][tex]= 16.4[/tex]

But remember here no of coaches can't be in decimal so we have to round it off to nearest tens place, Hence no of coaches will be 17.

Hence 17 coaches are needed.

Answer:

It has a slope of zero because the change in the y-values is 0.

Step-by-step explanation:

The line passes through points (9, 30) and (18, 30) and has a slope of zero because the change in the y-values is 0.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A line passes through the points (9, 30) and (18, 30).

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

∴ Slope(m) = (30 - 30)/(18 - 9).

Slope(m) = 0/9.

Slope(m) = 0.

The line has a slope of zero because the change in the y-values is 0.

So it must be a line parallel to the x-axis.

Answer:

24/25

Step-by-step explanation:

Step 1: Define systems of equation

10x - 16y = 12

5x - 3y = 4

Step 2: Rewrite one of the equations

5x = 4 + 3y

x = 4/5 + 3y/5

Step 3: Solve for y using Substitution

Step 4: Substitute y back into an original equation to solve for x

Step 5: Check to see if solution set (14/25, -2/5) is a solution.

Here, we see that x = 14/25, y = -2/5 and solution (14/25, -2/5) indeed works.

Step 6: Find x - y

x = 14/25

y = -2/5

Answer:

[tex]\displaystyle x-y=\frac{24}{25}[/tex]

Step-by-step explanation:

We are given the system:

[tex]\left\{ \begin{array}{ll} 10x-16y=12 & \quad \\ 5x-3y=4& \quad \end{array} \right.[/tex]

And asked to find the value of x - y if (x, y) is a solution to the above system.

Thus, let's solve the system. We can use eliminiation

We can see that the coefficients of x share a LCM.

Multiplying the second equation by negative two yields:

[tex]\left\{ \begin{array}{ll} 10x-16y=12 & \quad \\ -10x+6y=-8 & \quad \end{array} \right.[/tex]

Adding the two equations yields:

[tex](10x-10x)+(-16y+6y)=(12+(-8))[/tex]

Simplify:

[tex]-10y=4[/tex]

Solve for y:

[tex]\displaystyle y = \frac{4}{(-10)} = -\frac{2}{5}[/tex]

To find x, substitute y for either equation and evaluate. The second equation states that:

[tex]5x-3y=4[/tex]

Substitute:

[tex]\displaystyle 5x-3\left(-\frac{2}{5}\right)=4[/tex]

Multiply:

[tex]\displaystyle 5x+\frac{6}{5}=4[/tex]

And solve for x:

[tex]\displaystyle \begin{aligned} 5x+\frac{6}{5} &= 4 \\ \\ 5x &= \frac{14}{5} \\ \\ x &= \frac{14}{25}\end{aligned}[/tex]

Hence, our solution to the system is:

[tex]\displaystyle \left(\frac{14}{25},- \frac{2}{5}\right)[/tex]

We want to find the value of:

[tex]x-y[/tex]

Substitute:

[tex]\displaystyle = \left(\frac{14}{25}\right) - \left(-\frac{2}{5}\right)[/tex]

Evaluate. Hence:

[tex]\displaystyle x - y = \frac{24}{25}[/tex]

And we're done!

Answer:

x=5/2 and y=3

Step-by-step explanation:

since AC is a perpendicular bisector, BC=CD

[tex]6x-6=3y[/tex] so [tex]6x=3y+6[/tex]

if AC = a

using pythagorean theorem:

[tex](6x-6)^2 + a^2 = (6x+1)^2[/tex]

[tex](3y)^2 + a^2 = (5y+1)^2[/tex]

simplifies to:

[tex]36x^2-72x+36+a^2=36x^2+12x+1[/tex]

[tex]9y^2+a^2=25y^2+10y+1[/tex]

further simplifies to:

[tex]84x-35=a^2[/tex]

[tex]16y^2+10y+1=(8y+1)(2y+1)=a^2[/tex]

so we now have

[tex]84x-35=(8y+1)(2y+1)[/tex]

plugging the first equation in we get

[tex]42y+84-35=(8y+1)(2y+1)=16y^2+10y+1[/tex]

[tex]42y+49=16y^2+10y+1[/tex]

[tex]16y^2-32y-48=0[/tex]

[tex]y^2-2y-3=0[/tex]

[tex](y-3)(y+1)=0[/tex] so [tex]y=-1, y=3[/tex]

y=-1 is impossible, so y=3

therefore x=15/6=5/2

Answer:

205/3 meters or 68.33 meters

Step-by-step explanation:

Perimeter = 2W + 2L

L = 2W - 5

230 = 2W + 2(2W - 5)

230 = 2W + 4W - 10

230 = 6W - 10

220 = 6W

W = 110/3 or 36.67 m

Add the Width into the formula for L to find the length

L = 2(110/3) - 5

L = 205/3 m or 68.33 m

Answer:

1). m∠ACE = 115°

2). m(∠DCB) = 35°

3). m(∠ACB) = 30°

Step-by-step explanation:

In the diagram attached,

1). AB and CD are the parallel lines and the line AC is a transverse,

  m(∠ABC) = 35°

  m(∠BAC) = 115°

  ∠BAC ≅ ∠ACE [Alternate interior angles]

  m(∠ACE) = m(∠BAC) = 115°

2). Since, AB and CD are the parallel lines and line CB is a transverse,

   ∠ABC ≅ ∠DCB [Alternate interior angles]

    m(∠ABC) = m(∠DCB) = 35°

3). From ΔACB,

    m(∠ACB) + m(∠CBA) + m(BAC) = 180°

    m(∠ACB) + 35° + 115° = 180°

    m(∠ACB) = 30°
