The length of the molecule is 6.75*10^-^4cm in scientific notation.

Data;

  • Width of molecule = 3*10^-6 cm
  • Number of molecules = 225

<h3>Length of the molecule</h3>

This can be calculated as the total length of the 225 molecules added together. To do this, we simply multiply both the numbers of the molecules by the width of the molecule.

This becomes;

3*10^-^6*225 = 0.000675cm = 6.75*10^-^4cm

The length of the molecule is 6.75*10^-^4cm in scientific notation.

Carmen has $30 in store bucks and a 25% discount coupon for a local department store. What maximum dollar amount can Carmen purc
hram777 [196]

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is \boxed{\$ 110}.

Further Explanation:

Given:

Carmen has \$ 30 in store bucks.

A 25\% discount coupon for a local department store.

The total amount should be less than \$ 60 before sales tax.

Explanation:

Consider the amount of the purchase as A.

The Carmen has \$ 30 in store bucks.

The new amount will be \left( {A - 30} \right).

There is a 25\% discount coupon for a local department store.

The amount after discount can be calculated as follows,

\begin{aligned}{\text{Amount}} &= \left( {1 - 0.25} \right) \times \left( {A - 30} \right) \\&= 0.75\left( {A - 30} \right) \\\end{alignedd}

The total amount should be less than \$ 60 before sales tax.

The maximum amount can Carmen purchases so that after her store bucks and discount are applied can be calculated as follows,

\begin{aligned}0.75\left( {A - 30} \right) &\leqslant 60 \\\frac{{0.75\left( {A - 30} \right)}}{{0.75}} &\leqslant \frac{{60}}{{0.75}} \\ A - 30 &\leqslant 80 \\A - 30 + 30 &\leqslant 80 + 30 \\A &\leqslant 110 \\\end{aligned}

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is \boxed{\$ 110}.

to make 2 batches of nut nars, jayda needs to use 4 eggs how many eggs used in each batch of nut bars
muminat
To solve this problem, we need to set up a proportion.

2 batches of nut bars/ 4 eggs = 1 batch of nut bars / x eggs.

To solve this proportion, we use cross products, or multiplying the numerator of one number by the denominator of the other and setting them equal to one another.

(4 eggs) (1 batch) = (2 batches) (x eggs)

4= 2x

2=x

Therefore, 2 eggs are used in each batch of nut bars.
