Solve for w in the equation: 0.4w + 2.45 = 8.75

Mathematics
1 answer:
ASHA 777 [7]3 years ago
3 0

Answer:

w= 15.75 or 15 3/4

Step-by-step explanation:

So I would multiply 100 on both sides to get rid of the decimals so I’d end up with 40w+245=875

Now solve it by subtracting 245 on both sides.

40w=630

now divided 40 on both sides

15 3/4

Final answer 15 3/4 or 15.75

Maria walked 3 km west and 4 km south calculate how far she is from her starting point.
Rufina [12.5K]

Answer:

5 km

Step-by-step explanation:

We are given the distances walked by Maria;

  • 3 km west and 4 km south

We are required to determine the displacement from her starting point;

  • We are going to use Pythagoras's theorem;

a² + b² = c²

Taking, the distances towards south and towards west as the legs of the triangle;

Then, c² = 3² + 4²

               = 25

         c  = √25

            = 5 km

Therefore, the displacement from the starting point is 5 km

A recipe uses 5 cups of milk to make 10 servings. If the same amount of milk is used for each serving, how many servings can be
Margaret [11]

Answer: 24 servings

Step-by-step explanation:

First and foremost, we should note that:

4 cups = 1 quart

Therefore, 3 quarts = 3 × 4 cups = 12 cups

Since she uses 5 cups of milk to make 10 servings, it means that 1 cup of milk is used to make 2 servings. Therefore, 12 cups would be used to make:

= 12 × 2

= 24 servings.
