The length of a bridge on a map is 1.5 cm. What is the actual length of the bridge in meters if the map is drawn at a scale of 1

Vitek1552 [10]

Answer:

The actual length of the bridge is 600 meters

Step-by-step explanation:

we know that

The scale on a map is

$\frac{1}{40,000}$

That means

1 unit on a map represent 40,000 units in the actual

1 cm on a map represent 40,000 cm in the actual

Remember that

$1/ m=100/ cm$

$40,000\ cm=40,000/100=400\ m$

we can rewrite the scale as

$\frac{1}{400}\frac{cm}{m}$

using proportion

Find out the actual length of the bridge in meters if the length of a bridge on a map is 1.5 cm.

Let

x ----> the the actual length of the bridge in meters

$\frac{1}{400}\frac{cm}{m}=\frac{1.5}{x}\frac{cm}{m}\\\\x=400(1.5)\\\\x=600\ m$

Can you help me with this question.

Sauron [17]

Answer:

27. (2x + 3)(x + 5)

Step-by-step explanation:

27.

Use the 'ac' method

a*c = 2 * 15 = 30

We need 2 numbers whose product is 30 and whose sum is 13.

3 and 10 look good so we write

2x^2 + 10x + 3x + 15

= 2x(x + 5) + 3(x + 5)

= (2x + 3)(x + 5) answer
