A piggy bank contains some dimes and nickels. There are 8 more dimes than nickels in the bank. There is a total of $1.40. How ma

A single rose sells for 50 cents, so buying two will cost $1 (50 cents multiplied by 2).

With 2 roses per dollar, spending $20 allows for the purchase of 40 roses.

They make $6 profit on $20 sales, which means they spend $14 on the 40 roses ($20 minus $6).

Dividing $14 by 40 roses gives a cost of $0.35 per rose.

Therefore, the vendor pays 35 cents for each rose.

I affirm that all of these statements are correct.

A function and its inverse, when graphed, exhibit symmetry about the line y = x. Without viewing your graphs, I can't specify if g or h is the inverse. Identify the function that reflects f over the diagonal line y = x, which passes through the origin. 

Answer:

Ants weigh approximately 118,615,000mg more.

Step-by-step explanation:

Based on a quick search, the average housefly weighs around 11.5mg, while an ant averages at 3.5mg. With these average weights, we can calculate the total weight of each species.

Flies: 3,990,000 * 11.5mg = 45,885,000mg

Ants: 47,000,000 * 3.5mg = 164,500,000mg

Consequently, it's clear that the 47 million ants possess a greater mass, specifically

164,500,000 - 45,885,000 = 118,615,000mg more

The selection is A ($83.39).
