Answer: 32/5

Step-by-step explanation: When multiplying two fractions together, remember that we can cross-cancel.

In this problem the 12 and 3 reduce to 4 and 1.

So we have 8/1 · 4/5.

Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 32/5.

Someone answer this please kinda struggling

Answer:

≈ 3927 litres

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = Ah ( A is the area of the base and h the height )

Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )

V = πr²h

= π × 100² × 125 = 1250000π cm³ ( divide by 1000 )

= $\frac{1250000\pi }{1000}$ = 1250π litres ≈ 3927 litres ( to the nearest litre )

Can some one help me. Solve this equation.

Marina86 [1]

$\bold{Given : 2^2^x^-^2 - 2^x^-^1 = 2^x - 2}$

$\bold{\implies (2^2^x) (2^-^2) - (2^x)(2^-^1) = 2^x - 2}$

$\bold{\implies \frac{(2^2^x)}{(2^2)} - \frac{(2^x)}{(2^1)} = 2^x - 2}$

$\bold{\implies \frac{(2^2^x)}{4} - \frac{(2^x)}{2} = 2^x - 2}$

$\bold{\implies \frac{[2^2^x - (2^x)(2)]}{4} = 2^x - 2}$

$\bold{\implies [2^2^x - (2^x)(2)] = (4)(2^x) - 8}$

$\bold{\implies 2^2^x - (2^x)(2) - (4)(2^x) + 8 = 0}$

$\bold{\implies (2^x)^2 - (2^x)(6) + 8 = 0}$

$\bold{Let\;us\;take : (2^x) = Z}$

$\bold{\implies Z^2 - 6Z + 8 = 0}$

$\bold{\implies Z^2 - 4Z - 2Z + 8 = 0}$

$\bold{\implies Z(Z - 4) - 2(Z - 4) = 0}$

$\bold{\implies Z = 4\;\;(or)\;\;Z = 2}$

$\bold{But : Z = 2^x}$

$\bold{\implies 2^x = 4\;\; (or) \;\; 2^x = 2}$

$\bold{\implies 2^x = 2^2\;\; (or) \;\; 2^x = 2^1}$

$\bold{\implies x = 2\;\;(or)\;\; x = 1}$

A shopkeeper sold 12 bags on the first day. The number became four times

dybincka [34]

The total number of the bags sold by the shopkeeper will be 65532.

<h3>What is number series?</h3>

The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.

So the mathematical expression will be given as:

$=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)$

$=12+48+192+768+3072+12288+49152\\\\=65532$

Hence the total number of the bags sold by the shopkeeper will be 65532.
