Answer:
17.6 m²
Step-by-step explanation:
Given the ratio of similar shapes = a : b, then
area of shapes = a ² : b²
Δ PTQ and Δ PRS are similar and so the ratio of corresponding sides are equal, that is
PT : PR = 6 : 9 = 2 : 3, thus
ratio of areas = 2² : 3² = 4 : 9
let the area of Δ PQT be x, then using proportion
=
( cross- multiply )
9x = 4(x + 22) ← distribute
9x = 4x + 88 ( subtract 4x from both sides )
5x = 88 ( divide both sides by 5 )
x = 17.6
Thus area of Δ PQT = 17.6 m²
For this, you have to plot the points on the graph. where it says right hand height, you go down to that number on the x axis (horizontal) and then up to the correct number for right foot length (vertical)
Answer:
The pressure at 50 feet is 2.51515 atm
Step-by-step explanation:
we are given equation as

where
p(d) gives the pressure, in atmospheres (atm)
a depth d in the sea (d is in feet)
We are given
d=50 feet
So, we can plug d=50 and find p


So,
The pressure at 50 feet is 2.51515 atm
