Kayson mixes 300 milliliterss of spinach, 200 mL of berries, and 42 mL of dressing to make a salad. There are sss milligrams of
Leya [2.2K]

Let T be total number of milligrams of vitamin C in our salad.

We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.

Let us find how much mg of vitamin C our each ingredient of salad will have.

We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.  

\text{Mg vitamin C in 300 ml spinach}=300\cdot\text{s mg}

\text{Mg vitamin C in 200 ml berries}=200\cdot\text{B mg}

\text{Mg vitamin C in 42 ml dressing}=42\cdot\text{D mg}

To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.

T=(300s+200B+42D)\text{ mg}

Therefore, our desired expression will be T=(300s+200B+42D)\text{ mg}.

Fiona's school is in the shape of a triangle, with three hallways connecting the corners. Fiona enters the building and walks 90
noname [10]

Answer:

between 30 yards and 150 yards

Step-by-step explanation:

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ----> the possible lengths of the third hallway in yards

<em>Applying the Triangle Inequality Theorem</em>

1) 90+60 > x

150 > x

Rewrite

x < 150 yd

2) 60+x> 90

x > 90-60

x > 30 yd

The possible lengths of the third hallway in yards is the interval

(30,150)

All real numbers greater than 30 yards and less than 150 yards

therefore

between 30 yards and 150 yards
