Change 7 3/8 from a mixed. number to to an improper fraction
ASHA 777 [7]
First, we set up the mixed number 7 3/8 with different colors, so it is easy to follow along:

7
3
8

Step 2 - Multiply
Next, we multiply the whole number by the denominator.

7 x 8 = 56

Step 3 - Add Numerator
Then, we add the numerator to the answer we got in Step 2.

56 + 3 = 59

Step 4 - Solution
Finally, to get the solution, we keep the original denominator and make the numerator the answer from Step 3. Thus, 7 3/8 as an improper fraction is:

Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
snow_lady [41]

Answer:

(\frac{1}{2}, \frac{-1}{2})

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: (x_{1}, y_1) and (x_2, y_2)

The midpoint formula would be (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}).

2) Based on this, we can easily find the midpoint of AB.

  • -3 would be x_1\\
  • -5 would be y_1
  • 4 would be x_2  
  • the next 4 would be y_2

3) With this information, we can solve for the midpoint.  

(\frac{-3+4}{2}, \frac{-5+4}{2}) --> (\frac{1}{2}, \frac{-1}{2}) --> This is your answer.

Write and solve an equation for the total number of possible combinations from flipping a coin 10 times.
vladimir2022 [97]

Step-by-step explanation:

every flip has 2 possible outcomes.

1 flip has 2.

2 flips have 2×2 = 2² = 4

3 flips have 2×2×2 = 2³ = 8

and so on.

the number of possible combinations flipping a coin n times is

C(n) = 2^n

for 10 flips

C(10) = 2¹⁰ = 1024

possible outcomes or combinations.
