a. About how far is it from Amarillo to Oklahoma City? Explain your reasoning. b. Driving at a constant speed of 70 miles per hour, will it be possible to make this trip in 3 hours? Explain how you know.​

Answers

Answer:

They are 260 miles apart. No it would not be possible.

Step-by-step explanation:

If they are 260 miles apart and you drive at a constant speed on 70mph. You will have to 260/70 which = 3.7 or 4 so it would not be possible.

Amarillo and Oklahoma City are [tex]260[/tex] miles apart.

It is not possible to make this trip in [tex]3[/tex] hours.

By using any geographical tool, such as the local map or you can use internet too to find the distance between Amarillo and Oklahoma City.

Amarillo and Oklahoma City are [tex]260[/tex] miles apart.

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]Time = \frac{Distance}{Speed}[/tex]

[tex]Time = \frac{260}{70}[/tex]

Time [tex]= 3.714[/tex] hours

So, it is not possible to make this trip in [tex]3[/tex] hours.

Add the like terms on the right side of the equation together.

[tex]\bf 8=a+3+4\\8=a+7[/tex]

find the zero of the function h(x) = 4x+2

Answers

I think what you mean here is to have x as 0. So 4(0) +2=2. So your answer is 2

Answer:

[tex]x=-1/2=-0.5[/tex]

Step-by-step explanation:

So we have the function:

[tex]h(x)=4x+2[/tex]

To find the zero(s) of a function, set the function equal to 0 and solve for x. So:

[tex]0=4x+2[/tex]

Subtract 2 from both sides:

[tex]-2=4x[/tex]

Divide both sides by 4:

[tex]x=-1/2=-0.5[/tex]

So, the zero of the function is -0.5.

This means that the graph (a line) crosses the x-axis at (-0.5, 0).

Step 2: Subtract 4x from both sides.

The actual distance between the library and train station is 500 ft. Explain how you

could find the distance between them in centimeters on the map.

Answers

Answer:

15,420 cm

Step-by-step explanation:

Given the actual distance between the library and train station to be 500 ft, to find the distance between them in centimeters, we ill convert 500 ft to cm as shown;

Given the conversion:

1 ft = 30.48cm

500ft = x cm

Cross multiply

x cm * 1ft= 30.48 cm * 500ft

x cm = 30.48 cm * 500ft/1ft

x cm = 15,240 cm

Hence the distance between them in centimeters on the map is 15,420 cm

Answers

Answer and Explanation:

Number of classes = 8

    Highest value =2300

  Lowest value = 1250

Class width= highest value – lowest value / number of classes

               = 2300 – 1250/8

                = 131.25 = 132

So, we can write class as 1250+132=1382

The price of 2 tons of gravel is $128.

Given:

The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

To find:

The price of 2 tons of gravel.

Explanation:

Let [tex]x[/tex] be the price of 1 ton of gravel.

Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].

It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

[tex]\dfrac{3}{8}x=24[/tex]

[tex]x=\dfrac{8}{3}\times 24[/tex]

[tex]x=8\times 8[/tex]

[tex]x=64[/tex]

Now, the price of 2 tons of gravel is:

[tex]2x=2(64)[/tex]

[tex]2x=128[/tex]

Therefore, the price of 2 tons of gravel is $128.
