Answer:

The real distance between the cities is 186.69 miles.

Step-by-step explanation:

The scale on the map says that 1.5 cm represents 40 miles.

1.5 cm represents = 40 miles

1 cm represents = \frac{40}{1.5} = 26.666666 ≈ 26.67

On the map the distance between Columbia, SC and Atlanta is 7 cm.

The real distance between the cities = 26.67 × 7 = 186.69 miles.

The real distance between the cities is 186.69 miles.

The ratio that can be used in the equation is 1.5cm per 40 miles. The proportion that is being asked in this problem assuming that we represent the true distance between the cities by x will be,
                                    7.5/x = 1.5/40
The value of x from the equation is 200 miles.

Anybody know this answer?​
V125BC [204]

Answer:

y = -4/5x + 3

Step-by-step explanation:

Chose any two points on the line:

(5, -2)

(-5, 6)

Slope = (y2 - y1) / (x2 - x1)

6 -(-2) / -5 - 5

8 / -10

-4/5

Equation:

y = mx + b

Plug in x and y using any coords and then plug in m (the slope):

-2 = -4/5 * 5 + b

-2 = -20/4 + b

-2 = -5 + b

Add 5 on both sides:

3 = b

Now our equation is:

y = -4/5x + 3

Simplify seven square root of three end root minus four square root of six end root plus square root of forty eight end root min
Cloud [144]

7\sqrt{3}- 4\sqrt{6} + \sqrt{48} - \sqrt{54} simplified as 11\sqrt{3}- 7\sqrt{6} or 1.909 .

<u>Step-by-step explanation:</u>

We need to Simplify seven square root of three end root minus four square root of six end root plus square root of forty eight end root minus square root of fifty four. Which is equivalent to 7\sqrt{3}- 4\sqrt{6} + \sqrt{48} - \sqrt{54} :

7\sqrt{3}- 4\sqrt{6} + \sqrt{48} - \sqrt{54}

⇒ 7\sqrt{3}- 4\sqrt{6} + \sqrt{48} - \sqrt{44}

⇒ 7\sqrt{3}- 4\sqrt{6} + \sqrt{16(3)} - \sqrt{9(6)}

⇒ 7\sqrt{3}- 4\sqrt{6} + 4\sqrt{(3)} - 3\sqrt{(6)}

⇒ 11\sqrt{3}- 4\sqrt{6}- 3\sqrt{(6)}

⇒ 11\sqrt{3}- 7\sqrt{6}

\sqrt{3} = 1.732 , \sqrt{6} = 2.449

⇒ 11(1.723)- 7(2.449)

⇒ 1.909

Therefore, 7\sqrt{3}- 4\sqrt{6} + \sqrt{48} - \sqrt{54} simplified as 11\sqrt{3}- 7\sqrt{6} or 1.909 .

Pleasee help me! Find the measure of &lt;a + &lt;b + &lt;c + &lt;d + &lt;e + &lt;f. Explain ​
larisa86 [58]

Step-by-step explanation:

By sum of angles on a straight line = 180°,

we have Angle A + Angle B = 180°,

Angle C + Angle D = 180°, and

Angle E + Angle F = 180°.

Hence Angles A + B + C + D + E + F = (180°) + (180°) + (180°) = 540°.
