A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible

Charra [1.4K]

Answer:

The smallest possible length is 0.83m

Step-by-step explanation:

Given

$Volume = 565L$

Required

The smallest length of the tank

Since the tank is cubical, then the volume is:

$Volume = Length^3$

This gives:

$565L= Length^3$

Express as $m^3$

$\frac{565m^3}{1000} = Length^3$

$0.565m^3 = Length^3$

Take cube roots of both sides

$0.8267m = Length$

Rewrite as:

$Length = 0.8267m$

Approximate

$Length = 0.83m$

Choose the correct simplification of the expression (2ab5)3. (1 point) Question 8 options: 1) 8ab15 2) 8a3b8 3) 5a3b15 4) 8a3b15

d1i1m1o1n [39]

Answer:

4). $8a^{3}b^{15}$

Step-by-step explanation:

The Given expression is that,

$(2ab^{5})^{3}$

On simplifying,

$(2ab^{5})^{3}$ = $(2ab^{5} )(2ab^{5}) (2ab^{5})$

= $(2^{3} ) * (ab^{5})^{3}$

= (2×2×2) × ( $ab^{5}$ × $ab^{5}$ × $ab^{5}$ )

= $8a^{3}b^{15}$

Thus, <u>option 4</u> i.e. $8a^{3}b^{15}$ is the correct simplification of the given expression.
