Inga [223]

Answer:

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the amount of sodium in 1oz of chips.

y is the amount of sodium in 1 cup of soda.

Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.

This means that $4x + y = 600$ , also $y = 600 - 4x$

Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium.

This means that:

$x + 4y = 300$

From the first equation, we have that $y = 600 - 4x$ . So

$x + 4(600 - 4x) = 300$

$x + 2400 - 16x = 300$

$15x = 2100$

$x = \frac{2100}{15}$

$x = 140$

$y = 600 - 4x = 600 - 4*140 = 40$

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.

María regala a su padre un best seller por su cumpleaños. Elige la encuadernación de tapas duras que tiene forma de prisma recta

iris [78.8K]

Answer:

<h2>María used only 792 square centimeters to cover the best seller.</h2>

Step-by-step explanation:

The volume of the best seller is about a rectangular prism, which is

$V= w \times l \times h$

Where $w$ is width, $l$ is length and $h$ is height.

In this case, we have

$w=12 \ cm\\l= 18 \ cm\\h= 6 \ cm$

Replacing values in the formula, we have

$V=12cm \times 18cm \times 6cm=1,296cm^{3}$

Now, according to the problem, 10% of paper covers the book, that means we need to find the suface area and then find the 90% of the paper missing. The formula for surface area is

$S=2wl+2lh+2hw$

Replacing values, we have

$S=2(12)(18)+2(18)(6)+2(6)(12)=432+216+144=792cm^{2}$

If 792 square centimeters is 10% of the total paper, then

$x=100\%\frac{792cm^{2} }{10\%} =7,920cm^{2}$

Therefore, there is 7,920 square centimeters of papers, but María used only 792 square centimeters to cover the best seller.

I don't really understand what you're asking, but if you're asking the sum of 8 plus 10, it's 18. Sorry if I didn't help, you can try clarifying though :)
