PLS HELP FOR 20 POINTS PLEASE THIS IS HARD (i think 20 i dont know i set it to 20 but who knows im new to this) sorry for talking to yall like you know humans and not people on internet

30 feet

Multiply

For every 1 mm on the map there are 200 miles of actual distance (third option)

8 cm, 26.8 cm, and 58 cm (last option)

Step-by-step explanation:

Question 1:

An airplane is 180 feet long. Blake makes a scale model of the airplane at 1:60  of its actual size how long is the model?

If the model is scaled down by 1/60, then the model is 60 times smaller than the actual airplane. Set the model size as "x" and so we can write this ratio.

1 / 60 = x / 180

Cross multiply (multiply 60 and x, and 180 and 1)

60x = 180

x = 3 feet

Question 2:

To produce an enlarged or reduced measure you the scale.

In order to find the measure, you multiply it by the scale factor.

Question 3:

A scale on a map is 1 mm: 200 miles

The question tells us that for every 1 mm, there are actually 200 miles. So the answer is the first option, For every 1 mm on the map there are 200 miles of actual distance.

Question 4:

What are the new dimensions if we expand the triangle below by a factor of 4.

If we multiply by the scale factor, 4, we get

2 * 4 = 8

6.7 * 4 = 26.8

14.5 * 4 = 58

Thus, the answer is 8 cm, 26.8 cm, and 58 cm (last option)

I hope this helps! Feel free to ask any questions!

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
