Answer : 400 cm square :)
Sorry if it’s incorrect ;-;
Answer:
18 women
Step-by-step explanation:
Sum the parts of the ratio, 7 + 2 = 9 parts
Divide 45 by 9 to find the value of one part of the ratio.
45 ÷ 9 = 5 ← value of 1 part, thus
7 parts = 7 × 5 = 35 ← number of men
2 parts = 2 × 5 = 10 ← number of women
We require to change the ratio to 5 : 4
The 5 part of the ratio represents the number of men, thus
35 ÷ 5 = 7 ← value of 1 part of the ratio, thus
4 × 7 = 28 ← number of women
Number of women required to join existing committee = 28 - 10 = 18
4 3/10 and 23/100 is the answer
The acceleration of the fire truck is 1.666 m/s².
<u>Step-by-step explanation:</u>
Acceleration is the measure of change in velocity with respect to time. So as the initial velocity of the fire truck is given as 0 km/hr and the final velocity is given as 66 km/hr. So at first the truck is at rest and on switching on the engine, the truck gets to the velocity of 66 km/hr in 11 seconds.

But first the units of velocity should be changed from km/hr to m/s
1 hour = 3600 seconds
1 km = 1000 m
So, 
Converted Velocity = 18.33 m/s
Then, the acceleration will be

Acceleration = 1.666 m/s²
So, the acceleration of the fire truck is 1.666 m/s².
