A sphere is dilated by a scale factor of 1.04 to create a new sphere. How does the volume of the new sphere compare with the vol

ume of the original sphere?

It's not clear what you mean by "dilated".  That's not really a mathematical
operation ... at least not on the level of math that we're operating on here.

I'm going to assume that you mean that the linear dimension of the sphere is
increased by a factor of  1.04 .  A sphere actually has only one linear dimension ...
its diameter, or what is equivalent, its radius.

The volume of a sphere is    V = (4/3) (pi) (radius)³    so we can see that
the volume changes as the cube of the radius.

If the radius increases by a factor of  1.04, then the volume also increases,
but by a factor of

       (1.04) x (1.04) x (1.04) = 1.124864

This is very interesting.  By increasing the diameter of the sphere only 4 percent,
you increased its volume by almost 12 and 1/2 percent.

535.29 = 400(1 + r) 5
joja [24]

Answer:

Step-by-step explanation:

(1+r)^5=\frac{535.29}{400} \\1+r=(\frac{535.29}{400}) ^{\frac{1}{5} } \\1+r \approx 1.06\\r \approx .06

one pound of swordfish costs as much as 1.5 pounds of salmon. Mrs. O pays $39 for 2 pounds of salmon and 3 pounds of swordfish.
Alex73 [517]

Answer:

Not sure which ratio you need, but 6/9 = 2/3

Step-by-step explanation:

1.5xsalmon=swordfish

$39 = 2lb salmon and 3lb swordfish

1lb salmon=$6           6+6 = 12

1lb swordfish=$9       9+9+9 = 27

12+27 = 39

+1 • (2p5q3x + 4p4q3x + 2p3q5x + p3q4x + 2p3q2 + 2p3x + 8q3x)

I would explain how to get it but it’s like 20 steps into getting this
Good luck though please tell me if I did any part of this problem wrong it might be some typos

In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot
Radda [10]

Answer:

CD = 4.4ft

Step-by-step explanation:

Given

DE = 12

\angle C = 70^\circ

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

tan(70) = \frac{DE}{CD}

Substitute 12 for DE

tan(70) = \frac{12}{CD}

Make CD the subject

CD = \frac{12}{tan(70)}

CD = \frac{12}{2.7475}

CD = 4.4ft --- approximated
