Teachers were asked what their favorite ice cream was. The ratio of teachers that prefer rocky road to mint is 5 to 2. If there

DerKrebs [107]

28 teachers prefer mint.

Step-by-step explanation:

Given,

Total number of teachers = 98

Ratio of teacher that prefer rocky road to mint = 5:2

Let,

x be the original number.

Teachers who like rocky road = 5x

Teachers who like mint = 2x

$5x+2x=98\\7x=98$

Dividing both sides by 7

$\frac{7x}{7}=\frac{98}{7}\\x=14$

Teachers who prefer mint = 2x = 2(14) = 28

28 teachers prefer mint.

Agata [3.3K]

2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6

Find the center and radius of the circle whose diameter has an endpoint at (-3, -4) and the origin.

Zina [86]

Given end points of diameter,

(x1,y1)=(-3,-4)

(x2,y2)=(0,0)

Now,

the equation of circle is,

(x-x1)(x-x2)+(y-y1)(y-y2)=0

or, (x+3)(x-0)+(y+4)(y-0)=0

or, x^2 +3x +y^2 +4y =0

or, x^2 +y^2 +3x + 4y=0

which is in the form of x^2 +y^2 +2gx +2fy + c=0

where,

g=3/2

h=2

c=0

Now,

$radius(r) = \sqrt{ {g}^{2} + {f}^{2} - c } \\ = \sqrt{ \frac{ {3}^{2} }{ {2}^{2} } + {2}^{2} - 0 } \\ = \sqrt{ \frac{9}{4} + 4} \\ = \sqrt{ \frac{25}{4} } \\ = \frac{5}{2}$
