Answer:

It would cost $ 34.5

Step-by-step explanation:

Given,

The cost of $\frac{3}{4}$ lb of chopped walnut = $ 3.45,

So, the cost of 1 lb of chopped walnut = $\frac{4}{3}\times 3.45$

$=4\times 1.15$

= $ 4.6,

Thus, the cost of 7.5 lbs of walnuts = 7.5 × cost of 1 b of walnut

= 7.5 × 4.6

= $ 34.5

Answer:

The cost of the 7.5 lbs of walnuts be $2.16 .

Step-by-step explanation:

As given

It costs $3.45 to buy $\frac{3}{4}$ lb of chopped walnuts.

i.e

$\$ 3.45 = \frac{3}{4}\ lb$

Now calculate the cost of one pound .

$Cost\ of\ one\ pound = \frac{3.45}{\frac{3}{4}}$

$Cost\ of\ one\ pound = \$ 0.2875$

Now calculated the cost of the 7.5 lbs of walnuts .

Cost of 7.5 lbs of walnuts = 7.5 × 0.2875

= $2.16 (Approx)

Therefore the cost of the 7.5 lbs of walnuts be $2.16 .

Scientific notation uses expression which gives easy access of order. The greatest number is $5.5 \times 10^5$ .It is greater by smallest number by 500 times.

<h3>How to convert a number to scientific notation?</h3>

It is usually of the form $a.bc.. \times 10^k$ exponent of 10 starts)

(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)

This notation is used to get some idea of how large or small a number is in terms of power of 10.

<h3>What are some basic properties of exponentiation?</h3>

If we have $a^b$ base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
