Answer:
a) 0.012ft³
b)2.09 lb
c)0.791 lb
d) 0.012ft³
e) 6 inches
Step-by-step explanation:
a) To determine the volume of the shell of the jar we must determine the volume of the hollow cylinder:

Where r is the inside radius and R the outer radius.

convert to cubic ft:

The volume of the glass shell is 0.012 ft³
b) The weight of the cylinder can be determined because we have the volume and the density. Weight is defined as the product of volume and density:

The weight of the jar is 2.09 lb
c) The displacement of water is just the density of water mutliplied by the volume of the jar:#

0.791 lb of water will be displaced.
d) The volume of the water displaced is:
[tex]=0.791/62.5=0.01266
e) The jar will be fully submerged because the density of the jar is larger than water.
Answer:
Answer:
The answer is 39°
Step-by-step explanation:
BAD = 90°
ADE = 51°
AED = 180° - BAD + ADE = 180° - 90° + 51°
= 39°
39° is the Final answer

2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
Answer:
A≈28.26 in^2
Step-by-step explanation:
We know the diameter is 6
We can find the radius
r = d/2
r =6/2 =3 inches
The area of a circle is given by
A = pi *r^2
A = pi*3^2
A = pi*9
We will use 3.14 to approximate pi
A ≅(3.14) *9
A≈28.26 in^2
Hi there, 2.5 to the third power=2.5*2.5*2.5=15.625, Therefore, the answer is D. 15.625
