Adrian went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 350 mg of sodium and each f

Marizza181 [45]

Answer:

Adrian would have to purchase 9 cans and 3 frozen dinners.

step-by-step explanation:

Let us consider the sodium is denoted by a variable "s"

Let us consider the can is denoted by a variable "c"

Each can of soup containing the sodium = s = 350 mg

Each frozen dinner containing the sodium = s = 700 mg

The number of cans purchased by Adrian = c = 9 cans

The total amount of sodium = 5250 mg

Total amount of sodium purchased by Adrian

in 9 cans = 9 × 35 = 3150 mg

Subtracting 5250 mg by 3150 mg will give 2100 mg

So, 5250 mg - 3150 mg = 2100 mg

Dividing 2100 mg by 700 mg of sodium of frozen sodium will give the value 3.

So, Adrian would have to purchase 3 frozen dinner.

<u>Hence, Adrian would have to purchase 9 cans and 3 frozen dinners to collectively contain 5250 mg of sodium.</u><u> </u>

Verification:

The total amount of sodium = 5250 mg

Total amount of sodium purchased by Adrian in 9

cans = 9 × 350 = 3150 mg

Total amount of sodium purchased by Adrian in 3 frozen dinners = 3 × 700 = 2100 mg

Total sodium = sodium purchased in cans + sodium purchased in frozen dinners

5250 = 3150 + 2100

5250 = 5250

a car rental company charges an initial fee plus a constant fee per kilometer driven this table compares a total distance driven

ollegr [7]

Answer:

$120

Step-by-step explanation:

The initial fee that was charged is the y-intercept of the equation that represents the situation given.

Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.

Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.

First, using two pairs, (105, 183) and (140, 204), find the slope (m):

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{204 - 183}{140 - 105} = \frac{21}{35} = \frac{3}{5}$

m = ⅗

To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into $y = mx + b$ .

$183 = \frac{3}{5}(105) + b$

$183 = 63 + b$

Subtract 63 from each side

$183 - 63 = b$

$120 = b$

The initial fee of the company is $120.

i am trying to put a fence around a garden that is in the shape of a regular hexagon. i know that the side of the garden is 6ft

finlep [7]

There are 6 sides to a hexagon and each side of the fence will be 6+2 = 8 feet

So you'll need 8*6 = 48 feet of fencing.
