What is cosA for this triangle? 48/55 55/73 55/48 48/73

mash [69]

For this case we must indicate the cosine of A, of the figure shown. By definition:

$Cosine (A) = \frac {Cateto\ adjacent\ to\ the \ angle} {hypotenuse}$

Substituting the values we have:

$Cosine (A) = \frac {48} {73}$

So, we have to:

$Cosine (A) = \frac {48} {73}$

Answer:

240 square inches

Step-by-step explanation:

1 foot = 12 inches

to convert 4/3 ft to inches, multiply by 12

4/3 × 12 = 16 inches

the area of a square = base × height

base = 16, height = 15

16 × 15 = 240 square inches

Math question! I appreciate any help!

saw5 [17]

Lateral faces are all the sides of the prisms EXCEPT the bases, which are the sides on the top and bottom. To find the area of the lateral faces we can use the formula: perimeter x height.

perimeter = 2 (6 + 8) = 2 x 14 = 28
height = 14
area of the lateral faces = perimeter x height = 28 x 14 = 392

Hope this helps!

Richie and bethany play basketball and practice shooting free throws after school. During one practice session, Richie attempted

mamaluj [8]

Answer:

Bethany did not do better than Richie because her average score was less than his.

Step-by-step explanation:

Average Value

The average or mean value of m successes out of n tries is given by:

$\displaystyle \bar x=\frac{m}{n}$

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

$\displaystyle \bar x=\frac{12}{15}=0.8$

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

$\displaystyle \bar x=\frac{8}{11}=0.72$

Bethany did not do better than Richie because her average score was less than his.
