Answer:

29568 people cheered for the runners at the start of the race

Step-by-step explanation:

From the question, the crowd lined up 5 feet deep on both sides of the street for the first mile.

This lined up crowd could be related to a rectangle that is 1 mile long and 5 feet wide.

First, Convert 1 mile to feet

1 mile = 5280 feet

Hence, the length of the rectangle is 5280 feet and the width is 5 feet.

Now, we will determine how many 5 feet by 5 feet square we can get from the 5280 feet by 5 feet rectangle. To do that, we will divide 5280 feet by 5 feet

5280 feet ÷ 5 feet = 1056

Hence, from the rectangle, we can get 1056 5 feet by 5 feet square.

From the question, you estimate that 14 people can comfortably fit in a square that measures 5 feet by 5 feet,

∴ 14 × 1056 people will comfortably fit in the crowed lined up 5 feet deep on one side of the street for the first mile.

14 × 1056 = 14784 people

This is the amount of people that will comfortably fit in the crowed lined up 5 feet deep on one side of the street for the first mile.

Since the crowd lined up on both sides of the street, then

2 × 14784 people will comfortably fit in the crowed lined up 5 feet deep on both sides of the street for the first mile

2 × 14784 = 29568 people

Hence, 29568 people cheered for the runners at the start of the race.

Answer: x = 2

Steps: x + 3= 8x - 11

Subtract three form both sides: x + 3 - 3 = 8x - 11 - 3

Simplify: x = 8x - 14

Subtract 8x from both sides: x - 8x = 8x - 14 - 8x

Simplify:  -7x = -14

Divide both sides by negative seven: -7x ÷ -7   =   -14 ÷ -7

Simplify:  x = 2

Answer:

x = 61°

y = 29°

Step-by-step explanation:

Since x°+29° is a right angle (90°), you would have to subtract 29 from 90 to get x.

90 - 29 = x

90 - 29 = 61

x = 61°

For y: You can infer that y°+x°=90° as well because the angles are corresponding angles. So to find y°, you would do the same thing as finding x.

90 - x = y

90 - 61 = 29

y = 29°

Answer:

i have no idea if you're looking for how many rides she can go on or the equation so i'll give you both lol.

Step-by-step explanation:

3t + 12 = 40

t represents the number of tickets (rides)

$12 is the entry fee.

$3 is the cost per ticket

to solve, use the subtraction property of equality. (subtract 12 from both sides)

3t + 12 - 12 = 40 - 12

3t = 28

divide each side by 3.

3t/3 = 28/3

28/3 = 9.3333...

amari can go on a maximum of 9 rides ($27) and stay within her budget of $40 or less.

$27 + $12 = $39.

she will have $1 left over.

The inequality in the given situation is 3t+12≤40

Given that, Amari can spend at most $40 at the fair.

Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Now, the cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.

Here, $3 per ticket, t, to ride the rides = 3t

So, the inequality is 3t+12≤40

Therefore, the inequality in the given situation is 3t+12≤40.

Answer:

x = 9/5 = 1 4/5

Step-by-step explanation:

5x - 6 = 3

    +6   +6

(add positive 6 to the negative 6 = - 6 + 6 = 0, and to the answer = 3 = 3 + 6 = 9)

5x = 9

÷5   ÷5

x = 9/5 (improper fraction)

Hello.

First, let's add 6 to both sides:

[tex]\tt{5x-6+6=3+6}[/tex]

[tex]\tt{5x=9}[/tex]

The next step is to divide both sides by 5:

Answer:

6, 8, 10.

Step-by-step explanation:

Let n be any integer.

Then our first even integer will be [tex]2n[/tex]

And the consecutive integers will be [tex]2n+2[/tex] and [tex]2n+4[/tex]

We want to find the integers such that the sum of twice the smallest number (2n) and three times the largest number (2n+4) is 42. In other words:

[tex]2(2n)+3(2n+4)=42[/tex]

Solve for n. Distribute:

[tex]4n+6n+12=42[/tex]

Combine like terms:

[tex]10n+12=42[/tex]

Subtract 12 from both sides:

[tex]10n=30[/tex]

Divide both sides by 10:

[tex]n=3[/tex]

So, the value of n is 3.

This means that our first even integer is 2(3) or 6.

So, our sequence of integers is: 6, 8, 10.

And we're done!

Notes:

We use 2n because anything integer multiplied by 2 ensures that the resulting number is even. Starting out, n can be either even or odd, but by multiplying it by 2, we will get an even number.

The given inequality shows an ellipse with a center at (1,-2)

The major axis will be   [tex]a=\sqrt{\dfrac{26}{9} }[/tex]

The minor axis will be   [tex]b=\sqrt{\dfrac{26}{4} }[/tex]

The equation of an ellipse is written in the form

[tex]\dfrac{(x-h)^2}{a^2} +\dfrac{(y-k)^2}{b^2} =1[/tex]

The center is (h,k) and the larger of a and b is the major radius and the smaller is the minor radius.

Now the given inequality is

[tex]9x^2+18x+4y^2+16y-11 > 0[/tex]

[tex]9x^2+18x+4y^2+16y > 11[/tex]

[tex]9(x^2-2x)+4(y^2+4y) > 11[/tex]

[tex]9(x^2-2x+1)+4(y^2+4y+4) > 11+9+16[/tex]

[tex]9(x^2-2x+1)+4(y^2+4y+4) > 26[/tex]

On further solving

[tex]9(x-1)^2+4(y+2)^2 > 26[/tex]

[tex]\dfrac{(x-1)^2}{\dfrac{26}{9} } + \dfrac{(y+2)^2}{\dfrac{26}{4} } > 1[/tex]

Thus by comparing the equation with the standard form

[tex]\dfrac{(x-h)^2}{a^2} +\dfrac{(y-k)^2}{b^2} =1[/tex]

Thus we can see that the center (h,k) is (1,-2)

The major axis will be [tex]a=\sqrt{\dfrac{26}{9} }[/tex]

The minor axis will be[tex]a=\sqrt{\dfrac{26}{4} }[/tex]

We'll need the slope formula which is

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\[/tex]

We subtract the y values together, and divide that over the difference in the x values when subtracted in the same order.

Let's find the slope of line DE

[tex]D = (x_1,y_1) = (6,1) \text{ and } E = (x_2,y_2) = (2,3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{3 - 1}{2 - 6}\\\\m = \frac{2}{-4}\\\\m = -\frac{1}{2}\\\\[/tex]

The slope of line DE is -1/2.

Next, compute the slope of line EF

[tex]E = (x_1,y_1) = (2,3) \text{ and } F = (x_2,y_2) = (-1,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-3 - 3}{-1 - 2}\\\\m = \frac{-6}{-3}\\\\m = 2\\\\[/tex]

The slope of line EF is 2.

Lastly, compute the slope of line FD

[tex]F = (x_1,y_1) = (-1,-3) \text{ and } D = (x_2,y_2) = (6,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - (-3)}{6 - (-1)}\\\\m = \frac{1 + 3}{6 + 1}\\\\m = \frac{4}{7}\\\\[/tex]

The slope of line FD is 4/7.

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

To recap everything so far, we found the following:

The product of the first two slopes gets us (-1/2)*(2) = -1 showing that DE is perpendicular to EF.

Perpendicular slopes multiply to -1 as long as neither line is vertical nor horizontal.

Since DE is perpendicular to EF, this proves we have a 90 degree angle at point E.

Therefore triangle DEF is a right triangle.
