The ratio of areas is given by:
A1 / A2 = 400/25 = k ^ 2
Therefore, the relationship of the sides is given by:
L1 / L2 = k
Clearing k we have:
k = root (400/25)
Rewriting we have:
L1 / L2 = k = 20/5
Answer:
The ratio of their corresponding sides is:
20: 5
The coordinates would be (3,0)
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Answer:
866.79
Step-by-step explanation:you can divide the total amount of money she pent divide it by the number of sets and the number you get is the price for each set.
Answer:
200 students are neither in the band nor on any sports team
Step-by-step explanation:
To solve this problem we first have to calculate the students who play in the band and those who do sports
To calculate the students who play in the band we have to calculate 30% of the total number of students
30% = 30/100
400 * 30/100 = 120
120 students play in the band
To calculate the students who do sport we have to multiply 1/5 by the total number of students
400 * 1/5 = 80
Now we have to subtract from the total the amount that they do sports or play in the band
(400 - 80) - 120 = 200
This means that 200 students are neither in the band nor on any sports team
