Answer:
y = 20/3 * x + 125/3
Question 4 : 3 hours study for score 55 (?)
Step-by-step explanation:
2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.
y = mx + b
m = (75 - 55) / (5 - 2) = 20/3
b = y - mx = 55 - (20/3) * 2 = 125/3
Equation: y = 20/3 x + 125/3
The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.
<h3>What is the volume of the sphere?</h3>
The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.
Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.
The volume of the dome will be calculated as below:-
SA = 13.924π
2πr² = 13.92π
r = √6.96
r = 2.63 feet
Volume = 2 / 3 πr³
Volume = ( 2 / 3 ) π ( 2.63)³
Volume = 12.24π cubic feet
Therefore, the volume of the spherical dome will be 12.9π cubic feet.

I am not 100% positive but I think it is 4117.66
Answer:
The bottom left square of the triangle in 90 degrees always so take 90 + 40 giving you 130,
a Triangle has 180 degrees in total so 180 -130 = 50 degrees for the last side
C I’m pretty sure hope this helps
