Jlenok [28]

Answer:

solve for x

4x-6=26

4x=26+6

x=32/4

x=8

area of rectangle=l*b

=26*14

=364

area of triangle=b*h/2

=18.4*20.4/2

=375.36/2

=187.68 m^2

for another side of a triangle

(18.4)^2+(20.4)^2=c^2

338.56+416.16=c^2

\sqrt{754.72}=c

27.47=c

27.5=c

now, perimeter of triangle=a+b+c

=27.5+18.4+20.4

=66.3 m^2

radius=diameter/2

=26/2

=13 ft

diameter=26 ft

circumference=2πr

=2*3.14*13

=81.64

Area of a circle=πr^{2}

=3.14*(13)^2

=3.14*169

=530.66 ft^2

A baseball manager has 11 players of the same ability. How many 9 player starting lineups can he
Lana71 [14]

Answer:

55

Step-by-step explanation:

Combination will be used here as teams are a group.

So using combination:

<em>No. of combination of 'n' things taken 'r' at a time</em>

<em>\limits^n {C} \,_r= \frac{n!}{r! (n-r)!}</em>

here n = 11 ,

r = 9

11<em>C</em>9 <em>=  \frac{11!}{9! (11-9)!} = \frac{11!}{9! (2!)}</em>

11<em>C</em>9<em> =</em><em> 55</em>

<em>Which are the possible 9 player starting lineups</em>

What is the solution to this system of linear equations?
Bogdan [553]

Good morning Sonny

y-4x=7

2y+4x=2

We need to solve -4x+y=7 for y

Now let's start by adding 4x to both sides

-4x+y+4x=7+4x

y=4x+7

Now substitute 4x+7 for y in 4x+2y=2 so we can find the value for x

4x+2y=2

4x+2(4x+7)=2

12x+14=2

Add -14 to both sides

12x=14-14=2-14

12x=-12

Now divide 12 to both sides so we can find x

12x/12=-12/12

x=-1

Now we need to find the value for y by substitute -1 for x in y=4x+7

y=4x+7

y=(4)(-1)+7

y=3

Work done ;)

Answer : x=-1 and y=3

               (-1,3)

                D
