Answer:

1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of mg of sodium in 1 oz of chips.

y is the number of mg of sodium in a cup of soda.

Bryan ate 5 oz of chips and drank 1 cup of soda for a total of 650 mg of sodium.

This means that:

[tex]5x + y = 650[/tex]

Jadyn ate 1 oz of chips and drank 5 cups of soda for a total of 250 mg of sodium.

This means that:

[tex]x + 5y = 250[/tex]

From the first equation:

[tex]y = 650 - 5x[/tex]

Replacing in the second

[tex]x + 5(650 - 5x) = 250[/tex]

[tex]x + 3250 - 25x = 250[/tex]

[tex]25x = 3000[/tex]

[tex]x = \frac{3000}{25}[/tex]

[tex]x = 120[/tex]

[tex]y = 650 - 5x = 650 - 5*120 = 650 - 600 = 50[/tex]

1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.

The value of the expression -8 * f(0) + 4 * g(-8) is -60

If the following equations represent the functions f(x) and g(x).

f(x) = 2/3x + 7 and g(x) = 2x + 15

Calculate the value of -8 * f(0) + 4 * g(-8)

We have:

f(x) = 2/3x + 7 and g(x) = 2x + 15

Calculate f(0) and g(-8)

f(0) = 2/3(0) + 7 and g(-8) = 2(-8) + 15

Evaluate

f(0) = 7 and g(-8) = -1

Substitute the above values in the following expression

-8 * f(0) + 4 * g(-8)

So, we have:

-8 * 7 + 4 * -1

Evaluate

-60

Hence, the value of the expression -8 * f(0) + 4 * g(-8) is -60

Answer:

12.54

Step-by-step explanation:

When finding the mean, first you add all the numbers in the data:

9+14+14+9+20+6+8+19+17+13+9=138

And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.

138\11=12.5454545

So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.

Answer:

[tex]in \: this \: shape \: you \: have \: two \: pieces \: one \: square \: ad \: half \: of \: circle \\ area \: of \: circle = 12 \times 12 = 144 \\ area \: of \: hafl \: of \: circle = 12 \times 12 \times 0.25 \times 3.14 = 113.04 \\ whole \: area = 144 + 113.04 = 257.04[/tex]

Answer: E. 200.5 ft

so first you’d find the area of the square which is 12 x 12 = 144 (area = length x width)

next, find the radius of the semi circle which is 12 divided by 2 (because we used the measurements from the square and the diameter is 12 and radius is half of diameter)

pretend your solving for a full circle and then divide it by 2 to get the answer for the semi circle since a semi circle is half of a circle (formula for circle A = pi r^2)

area of circle = 113.04 divided by 2 to get semi circle = 56.5

then add both areas together

56.52 + 144 = 200.5

Answer:

A. P = 72 feet, A = 300 square feet

Step-by-step explanation:

✔️Perimeter = sum of all sides of the polygon = 15 + 16 + 17 + 8 + 16 = 72 ft

✔️Area of the polygon = area of a trapezoid = ½(a + b)h

Where,

a = 16 ft

b = 16 + 8 = 24 ft

h = 15 ft

Substitute

Area = ½(16 + 24)15

Area = ½(40)15

Area = 300 ft²

Answer:

0.1875 miles (or 3/16 of a mile)

Step-by-step explanation:

In order to make the math easier for calculating the distance, the values have to be calculated to whole hours.

1.75*2 = 3.5

2.5 * 3 = 7.5, 7.5/2 = 3.75

Now, I divide the whole hours into quarters

3.5/4 = 0.875

3.75/4 = 0.9375

Multiply both values by 3 to get the distance after 3/4 of an hour

0.875 = 2.625

0.9375 = 2.8125

remove the smaller value from the larger value

2.8125 - 2.625 = 0.1875

I might have used a more over-complicated method than what you might have been taught, but it should be just as efficient. Good luck with your assignment!

Answer:

smaller, divide, 12, and 39 yards

Step-by-step explanation:

An inch is smaller than a yard, so multiply the number of inches by 3 to find the number of yards.

Unit conversion is the process of converting a measurement from one unit of measurement to another equivalent unit of measurement. For example, converting a measurement from meters to centimeters, or from pounds to kilograms.

An inch is smaller than a yard, so multiply the number of inches by 3 to find the number of yards.

Unit conversion is important in many fields, including science, engineering, construction, and even everyday life. For example, in science and engineering, it is common to work with different units of measurement, and converting between them is essential for accurate calculations and analysis.

Therefore, 468 inches is equal to 13 yards.
