Let x = number of students then by proportion:-

5/7 = 185 / x

x = (7 * 185) / 5

= 259 Answer

V is themidpoint of UW. If UV = x + 8 and VW = 9x, what is VW?

user100 [1]

Answer:

x=1

Step-by-step explanation:

If V is the midpoint of the line UW, that would mean that there's an equal distance between UV and 9x. So, the value of UV and VW would eed to be the same.

x+8=9x

8=8x

x=1

Identify the equation of the circle that has its center at (16, 30) and passes through the origin

Veronika [31]

To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

$(x - 16)^2 + (y - 30)^2 = 1156$

Equation of a circle:

The equation of a circle with center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

Center at (16, 30)

This means that $x_0 = 16, y_0 = 30$

Thus

$(x - 16)^2 + (y - 30)^2 = r^2$

Passes through the origin:

We use this to find the radius squared, as this means that $x = 0, y = 0$ is part of the circle. Thus

$(x - 16)^2 + (y - 30)^2 = r^2$

$(0 - 16)^2 + (0 - 30)^2 = r^2$

$r^2 = 16^2 + 30^2 = 1156$

Thus, the equation of the circle is:

$(x - 16)^2 + (y - 30)^2 = 1156$

Write an expression to represent the phrase, "6 of one thing plus half a dozen of the other"

yawa3891 [41]

'of' means multiply
half a dozen means 12/2=6

6 of one thing means 6 times x
plus means ad
half a dozen of another mean 6 times y

they are added

6x+6y

2 variables
it says 'of the other' so they are diferent
