Answer:

Step-by-step explanation:

The perpendicular diameter to the chord divides it into two congruent parts.

Since

VU⊥XS,
XT=3b-1,
TS=b+5,

we have that XT=TS.

Hence,

3b-1=b+5,

3b-b=5+1,

2b=6,

b=3.

So,

XT=3·3-1=9-1=8

TS=3+5=8

and

XS=XT+TS=8+8=16.

Thirteen people on a softball team show up for a game. a)How many ways are there to choose 10 players to take the field? b)How m

marishachu [46]

Answer:

a) 286

b) 1,037,836,800

c) 285

Step-by-step explanation:

a) Since order is not important, the total possible number of ways to choose 10 players out of 13 is the following combination:

$C(13,10)=\frac{13!}{(13-10)!10! } \\C(13,10)=\frac{13*12*11*10!}{(3*2*1)10! }\\C(13,10) = 286$

b) The total number of possibilities to assign positions by the selecting 10 players is the permutation of 13 players for 10 positions:

$P(13,10) = \frac{13!}{(13-10)!}\\P(13,10) = 13*12*11*10*9*8*7*6*5*4\\P(13,10) =1,037,836,800$

c) The number of ways to pick 10 players including at least one woman is equal to the total number of ways to pick 10 players (found in item a) minus the the number of ways to pick 10 players without picking a single woman.

Since there 10 male players for 10 positions, there is only one possible way to pick a team without women, therefore:

$P=286-1 =285$

Two-thirds of a number added to itself is 20. What is the number?

vivado [14]

Answer:

Step-by-step explanation:

2/3 x + x = 20

2/3 x + 3/3x = 20

5/3 x = 20 ... times 3/5 both sides

x = 12

check: 2/3 x 12 + 12 = 8 + 12 = 20

The square is 90 degrees & the triangle has 180 degree but I need help to solve

9966 [12]

Answer:

x= 44°

Step-by-step explanation:

Since a triangle is 180° in total, if you take 46° and 90° and subtract it from 180°, you will get 44° for x.
