__ uniforms

70

Step-by-step explanation:

There are 7 options for blouses.  Each blouse can be matched with one of 10 skirts.  So the total number of combinations is:

7 × 10 = 70

70 uniforms

Step-by-step explanation:

A girls' choir is choosing a uniform for their concert. There are 7 options for the uniform's blouse and 10 skirt options. Therefore, there are 10 different uniforms that the girls' choir can choose.

7 ⋅ 10 = 70

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

1/5^2 = 7.56/45
