One side: y+4
Second side: y+4+2=y+6
Third side: 2(y+4)-3= 2y+8-3= 2y-5
Perimeter = y+4+y+6+2y-5= 4y+5
Answer:
405
Step-by-step explanation:
1% - 9 people
45% - 9 × 45 = 405 people
Answer:
Step-by-step explanation:
Given
Balloon in the east makes an angle of elevation of
and is at height of 461 m
Balloon in the west makes an angle of elevation of
and is at height of 296 m
Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m
and net height of Blue balloon is 294.4 m
using trigonometry




Distance between two Balloons


Answer:
12.4 cm³
Step-by-step explanation:
From the picture attached,
Radius of the circular top of the cone =
= 
Height of the cone = h
Lateral height of the cone = h
By applying Pythagoras theorem in the right triangle of the cone,
l² = r² + h²
6² = 1² + h²
h = 
h = 
Ice cream needed to fill one cone = Volume of the cone
Since, formula for the volume of the cone V = 
V = 
= 6.195
≈ 6.20 cm³
Ice cream needed to fill the two cones = 2 × 6.20
= 12.4 cm³
Therefore, ice cream needed to fill the two cone = 12.4 cm³
I don’t know the question isn’t making any sense at least to me
