The volume of a sphere whose diameter is 18 centimeters is

Akimi4 [234]

Answer:

volume before reducing is 8 times the volume after reducing

Step-by-step explanation:

volume before reducing=

V=4/3πr³=

V=4/3π(9)³=972π cm³

diameter reduced to half=18/2=9 cm

radius=d/2=9/2=4.5 cm

volume of sphere when diameter reduced by 1/2=

V=4/3πr³

v=4/3 (π)(4.5)³=121.5π

<h2>volume before reducing is <u>8</u> times the volume after reducing</h2>

Q. 3. On a recent math test, Aubrey was asked to find the LCD of and and then to write equivalent fractions using this LCD. Aubr

Darina [25.2K]

The Lowest Common Denominator of 3 and 4 is the denominator that will

simplify mathematical operations such as addition of the fractions.

The mistake is the LCD of 3 and 4 is 12 rather than 24

Reasons:

The given fractions are;

$\displaystyle \frac{1}{3} \ and \ \mathbf{\frac{2}{4}}$

The Lowest Common Denominator, is given by the Least Common Multiple of the denominators, which is 3 × 4 = 12

Therefore;

The LCD = 12

The equivalent fractions are therefore;

$\displaystyle \frac{1}{3 } = \frac{4 \times 1}{4 \times 3} = \mathbf{\frac{4}{12}}$

$\displaystyle \frac{2}{4} =\frac{3 \times 2}{3 \times 4} = \mathbf{ \frac{6}{12}}$

$\displaystyle The \ equivalent \ fractions \ are \ \frac{4}{12} \ and \ \frac{6}{12}$

Therefore, the mistake is using a LCD of 24 rather than 12, given that 12 is lower than 24 and therefore is the LCD of 3 and 4.

By having an LCD of 12, we have;

The equivalent fractions with the LCD will be; $\displaystyle \frac{4}{12} \ and \ \frac{6}{12}$

Answer:

G

Step-by-step explanation:

LS and TD are in the same positions in the equation. S is the first letter and D is so they are equal to each other and the same for L and T

$12.25 pen set; 33% discount What is the sale price

taurus [48]

Answer:

Hey there! The answer is $8.21

Step-by-step explanation:

First, you must multiply the original price, 12.25, by the discount, 33%:

12.25*0.33

≈4.04

Now, subtract this amount from the original price:

12.25-4.04

=8.21

Hope this helps!
