A.) it's a 90° angle 
     90=6x+4x+10
     90=10x+10
    -10         -10
     80=10x
     divide both sides by 10, x=8
B.) it's a 180° angle
     180=5x+13+3x+7
     180=8x+20
     -20        -20
     160=8x
     divide both sides by 8, x=20
C.) it's a 180° angle
     180=3x+5+2x+18+2x+17
     180=7x+40
     -40        -40
     140=7x
     divide both sides by 7, x=20
D.) it's a 180° angle
     180=90+30+x
     180=120+x
     -120  -120
     60=x

Konrad raised $75.50 for his football team. He raised 151% of his fundraising goal how much more then his fundraising did Konrad
Colt1911 [192]

Answer:

He raised $25.50 over his fund raising goal

Step-by-step explanation:

Here, we want to calculate his fund raising goal.

Let his fund raising goal be $x

We are told that he raised 151% of his fundraising goal;

Thus,

mathematically;

151% of x = 75.5

151/100 * x = 75.5

151x = 100 * 75.5

151x = 7550

x = 7550/151

x = $50

So the amount he raised over his fund raising goal will be $75.50 - $50 = $25.50

A pet toy manufacturer is designing a plastic ball for dogs that will float in water. In order for the ball to float it must hav
algol13

Answer:

3.576 cm

Step-by-step explanation:

radius of ball, r=?

Given:

Density, p = 0.600g/mL

mass, m= 115g

finding volume, v of ball by using formula p=m/v

v= m/p

= 115/0.600

=191.666 mL^3

=191.666 cm^3

Now using formula v= (4/3)πr^3 to find radius, r of the ball

r^3= 3v/4π

   = 3(191.666)/4π

   =45.75 cm

r   =3.5767 cm !
