5 1/6 divided by 7/10<br> (simplify and make a fraction)

True [87]

Answer:

$\frac{155}{21}$

Step-by-step explanation:

$5\frac{1}{6} = \frac{31}{6}$
Re-write the expression: $\frac{31}{6}$ ÷ $\frac{7}{10}$
31/6 ÷ 7/10 = 31/6 × 10/7
$\frac{31}{6}$ × $\frac{10}{7} = \frac{310}{42}$
310/42 = 155/21

I hope this helps!

A spherical balloon has a 34-in. diameter when it is fully inflated. Half of the air is let out of the balloon. Assume that the

jeka57 [31]

Answer:

a. 20,579.52 cubic inches

b.10,289.76 cubic inches.

c. 13.49 inches

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of a sphere:

Volume of a sphere: 4/3 π r³

Since diameter (d) = 2 radius (r)

Replacing with the value given:

34 =2r

34/2=r

r= 17 in

Back with the volume formula:

V = 4/3 π r³

V =4/3 π (17)³

V = 20,579.52 cubic inches

The volume of the half-inflated balloon is equal to the volume of the sphere divided by 2.

20,579.52/2 = 10,289.76 cubic inches.

To find the radius of the half-inflated balloon we have to apply again the volume formula and substitute v=10,289.76

10,289.76= 4/3 π r³

Solving for r

10,289.76/ (4/3 π)= r³

2,456.5 = r³

∛2,456.5 = r

r = 13.49 inches

A cylindrical soup can has a height of 8 in. and a radius of 3in. If the height is doubled on a second soup can, what will be th

kykrilka [37]

Answer:

The ratio of the volumes of the two soup cans is 2.

Step-by-step explanation:

The volume of a cylinder can be written as:

$V=\pi r^2h$

where r is the radius of the base and h is the height.

If the height of the second cylinder doubles the height of th first cylinder, the ratio of volume between the second and the first cylinder is:

$\dfrac{V_2}{V_1}=\dfrac{\pi r^2 h_2}{\pi r^2 h_1}=\dfrac{\pi r^2 (2h)}{\pi r^2 h}=\dfrac{2}{1}=2$

The ratio of the volumes of the two soup cans is 2.
