If 18 people ride in 3 cars how much people ride in 1 car?

We know that:

[tex]\large\tex\text{Circumference of circle} = 2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches}[/tex]

[tex]\large \pi = \dfrac{22}{7}[/tex]

Somehow, we need to find the radius of the circle. To do that, we need to isolate 'r'.

Isolating 'r':

To isolate "r", we need to divide both sides by 2, then divide both sides by 22/7. You can also multiply 22/7 and 2 and then divide the result both sides to isolate "r".

Step-1: Divide both sides by 2.

[tex]2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches} \\\\\\\ \dfrac{2\pi r}{2} = 35 \dfrac{13}{21} \div 2 \\\\\\ \pi r = \dfrac{35 \times 21 + 13}{21} \div 2 \\\\\\\pi r = \dfrac{748}{21} \times \dfrac{1}{2} \\\\\\\ \pi r = \dfrac{374}{21}[/tex]

Step-2: Divide π both sides.

[tex]\dfrac{\pi r}{\pi} = \dfrac{374}{21} \div \pi \\\\\\ r = \dfrac{374}{21} \div \dfrac{22}{7} \\\\\\ r = \dfrac{374}{21} \times \dfrac{7}{22} \\\\\\ r = \dfrac{17}{3}[/tex]

Now, let's multiply the radius by 2 to obtain the diameter.

Obtaining the diameter:

[tex]\tex\text{Diameter = 2(Radius)} \\\\\\ \tex\text{Diameter} = 2(\dfrac{17}{3} ) \\\\\\ \boxed{\bold{Diameter = \dfrac{34}{3}}}[/tex]

[tex]\\ \rm\rightarrowtail \pi d=35\dfrac{13}{21}[/tex]

[tex]\\ \rm\rightarrowtail \pi d=\dfrac{748}{21}[/tex]

[tex]\\ \rm\rightarrowtail d=748/21\pi[/tex]

[tex]\\ \rm\rightarrowtail d=11.34in[/tex]

Answer:

? = 42 degrees

Step-by-step explanation:

The 105 is part of a 180 degree angle so we do 180-105 giving us 75 degrees. and the sum of the internal angles of a triangle should equal 180. so we add 57 + 75 giving us 132. 180-132 will be 48 degrees.

Answer:

D

Step-by-step explanation:

The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.

Let's take a look at each end.

As x approaches negative infinity:

We can see from the graph that as x approaches negative infinity (a.k.a as x goes towards the left), the graph is curving upwards.

Therefore, as x approaches negative infinity, f(x) approaches positive infinity.

Therefore, the end behavior of the left is:

[tex]\text{As } x\rightarrow -\infty, f(x)\rightarrow\infty[/tex]

As x approaches (positive) infinity:

We can see from the graph that as x approaches positive infinity (as x is moving towards the right), the graph f(x) is curving downwards.

Therefore, as x approaches positive infinity, f(x) approaches negative infinity.

Therefore, the end behavior of the left is:

[tex]\text{As } x\rightarrow\infty, f(x)\rightarrow-\infty[/tex]

So, our answer is D.

And we're done!

Answer:

The cost of one student ticket = $6

Step-by-step explanation:

They were charged for three student tickets and two adult tickets.

Let the cost of one student ticket = a

Let the cost of one Adult ticket = b

If a student ticket costs 3/4 as much as an adult ticket costs

a = 3/4(b)

= 3b/4

For his family of 5 to play it costs $34.

Hence:

3a + 2b = $34

a = 3b/4

3(3b/4) + 2b= 34

9b/4+ 2b = 34

9b + 8b / 4 = 34

17b/4 = 34

17b = 34 × 4

b = 136/17

b = $8

The cost of one Adult ticket = $8

Note that:

a = 3b/4

a = 3(8)/4

a = 24/4

a = $6

Therefore, the cost of one student ticket = $6

Answer:

1/6

Step-by-step explanation:

-4/9 * (-3/8) =

Answer:

Step-by-step explanation:

-4/9 x -3/8 = (-4)(-3) / 8x9 = 12 / 72 = 6/36 = 1/6

Answer:

The solution(s) to a system of equations is the point(s) of intersection.

To find the solution, equate the equations and solve for x to find the x-coordinate:

[tex]\implies f(x)=g(x)[/tex]

[tex]\implies 3x+2=[x-1]+1[/tex]

[tex]\implies 3x+2=x[/tex]

[tex]\implies 2x=-2[/tex]

[tex]\implies x=-1[/tex]

Now substitute the value of x into one of the equations to find the y-coordinate of the solution:

[tex]f(-1)=3(-1)+2=-1[/tex]

So the solution to this system of equations is (-1, -1)

Therefore, (1, 5) is NOT a solution to the system of equations.

Let's check

[tex]\\ \rm\rightarrowtail y=3x+2[/tex]

[tex]\\ \rm\rightarrowtail 5=3+2[/tex]

[tex]\\ \rm\rightarrowtail 5=5[/tex]

Verified

And

[tex]\\ \rm\rightarrowtail y=[x-1]+1[/tex]

[tex]\\ \rm\rightarrowtail 5=1-1+1[/tex]

[tex]\\ \rm\rightarrowtail 5\neq 1[/tex]

Answer:

7.5%

Step-by-step explanation:

one year has 12 months...and in one month the person saves 200

so in one year it will be 200×12 = 2400

%save=total saves/total earning×100

= (2400/32000)×100 = 7.5%

Answer:

(8(2 + 4)

Step-by-step explanation:

Answer:

A, D, E are equivalent expressions.

Step-by-step explanation:

A)

[tex]\dfrac{2}{3}a+\dfrac{5}{3}b + ( 8 + 4) - 4 =\dfrac{2}{3}a +\dfrac{5}{3}b + 12 - 4\\\\=\dfrac{2}{3}a+\dfrac{5}{3}b + 8\\\\[/tex]

Here, 8+4 = 12 and when we subtract 4 from 12, we get 8.

[tex]D) 6*(\dfrac{2}{3}a+\dfrac{5}{3}b+8)*\dfrac{1}{6}=6*\dfrac{1}{6}(\dfrac{2}{3}a+\dfrac{5}{3}b+8)\\\\\\=\dfrac{2}{3}a+\dfrac{5}{3}b + 8[/tex]

Here, 6 and 1/6 will be cancelled and we get 1.

[tex]E) \dfrac{2}{3}a+\dfrac{5}{3}b+ 0*\dfrac{1}{3}c+8=\dfrac{2}{3}a+\dfrac{5}{3}b+0+8\\\\=\dfrac{2}{3}a+\dfrac{5}{3}b+8[/tex]

0 multiplied by any value is 0. So, term multiplied by 0 = 0

the function is

y = mx + c

m is the gradiant (change)

c is the y-intercept (when x = 0)

first m

it is decreasing by 3 %

3% as a decimal = 0.03

Answer:

Step-by-step explanation:

Sum of interior adjacent angle is 180 degrees.

Given  

m∠BNR=12w-19,

m∠RNA= ¼(w+199)

m∠BNA=2(12w-19).

Substitute

m∠BNR+m∠RNA=

¼(w+199)+12w-19, = 2(12w-19).

W+796+48W-76 = 96W-152

49W-96W = -152+76-796

-47W = 872

W = 872/47

W = 18.55

Answer:

The money in an account that earns 4.4% interest per year = 22500

The rest into an account that earns 6% interest per year = 13500

Step-by-step explanation:

Interest = Principal × Rate × Time

Let x = money saved in account A

Let y = money saved in account B

Brandon has 36000 to invest and wants to earn 5% interest per year

x + y = 36000..... Equation 1

x = 36000 - y

He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year.

Hence:

4.4% × x × 1 + 6% × y × 1 = 36000 × 5% × 1

0.044x + 0.06y= 1800....... Equation 2

Substitute 36000-y for x in Equation 2

0.044(36000 - y) + 0.06y = 1800

1584 -0.044y + 0.06y = 1800

-0.044y + 0.06y = 1800 - 1584

0.016y = 216

y = 216/0.016

y = 13500

Note that:

x = 36000 - y

x = 36000 - 13500

x = 2250

Therefore,

The money in an account that earns 4.4% interest per year = 22500

The rest into an account that earns 6% interest per year = 13500

Answer:

x₁ > x₂

Step-by-step explanation:

Both actions imply a parable trajectories, since both are projectile shot cases.

Let´s call x₁ maximum distance in the first case

The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.

In the second case, the parable curve is modeled by:

y = x₂*( 0.08 - 0.002x₂)    or  y = 0.08*x₂ - 0.002*x₂²

A second degree equation, solving for x₂ and dismissing the value x₂ = 0

we get:

y = 0       ⇒    x₂*( 0.08 - 0.002x₂) = 0    x₂ = 0

And 0,08 - 0.002*x₂ = 0

- 0.002*x₂ = - 0.08

x₂ = 0.08/0.002

x₂ = 40 f

Then  x₁ > x₂
