The answer is b. 200

<span>If y varies inversely as x, then: y = c/x

We know:
y = 40
x = 5

y = c/x
c = y * x
c = 40 * 5
c = 200</span>

Answer:

b. 200

Step-by-step explanation:

We have been given that y varies inversely as x.

Since we know that equation that represents the inversely proportional relation between y and x is:y=\frac{k}{x}, where,

k= Constant of proportionality.

Upon substituting our given values in above equation we will get,

40=\frac{k}{5}

Let us multiply both sides of our equation by 5.

40\times 5=\frac{k}{5}\times 5

200=k

Therefore, constant of proportionality for our given quantities is 200 and option b is the correct choice.

Need help with solving both of these questions for geometry homework.
faltersainse [42]

Answer:

m<R = m<T = 80.5 deg

Step-by-step explanation:

3)

Since WXYZ is a square, <WXZ is formed with a diagonal of the square and has measure 45 deg.

m<WXZ = 8x - 19 = 45

8x - 19 = 45

8x = 64

x = 8

4)

Draw the kite. Make sure that segments QR and RS are not congruent. Fill in the given angle measures. Angles R and T are congruent opposite angles.

The sum of the measures of the interior angles of a convex, n-sided polygon is

180(n  2).

A kite is a quadrilateral, so n = 4.

180(4 - 2) = 180(2) = 360

The sum of the measures of the interior angles of a kite is 360 deg.

m<Q + m<R + m<S + m<T = 360

75 + m<R + 124 + m<T = 360

m<R + m<T + 199 = 360

m<R + m<T = 161

m<R = m<T, so we substitute m<T with m<R.

m<R + m<R = 161

2m<R = 161

m<R = 80.5

m<R = m<T = 80.5 deg
