For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = one-half?

likoan [24]

Answer:

V=16

Step-by-step explanation:

We are given that an inverse variation

$p=\frac{8}{V}$

We have to find the value of V when p=1/2

To find the value of V we will substitute the value of p

Substitute the value of p

Then, we get

$\frac{1}{2}=\frac{8}{V}$

$\frac{V}{2}=8$

Using multiplication property of equality

$V=8\times 2$

Using multiplication property of equality

$V=16$

Hence, the value of V=16

Answer

y = 0.2x − 7

Step-by-step explanation:

Find the slope first by subtracting (10, -5) and (5, -6) in slope formula, this will equal 1/5 or 0.2

Then find the y-intercept which is the point that crosses the y-axis, in this case -7 is the y-intercept

Finally format in y=mx + b for slope-intercept form

y=0.2x-7

Simone measures the width of one of cardboard strip as 1/2 yard. A second cardboard strip measures 5/6 yard in width. Estimate t

Zepler [3.9K]

Answer:

The correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.

Step-by-step explanation:

Consider the provided information.

Simone measures the width of one of cardboard strip as 1/2 yard.

A second cardboard strip measures 5/6 yard in width.

We need to find the combined width.

The combined width of the cardboard strip:

$\frac{1}{2} + \frac{5}{6}=\frac{8}{6}=1\frac{1}{3}$

$1\frac{1}{3}$ is closer to $1\frac{1}{4}$ as compare to $1\frac{1}{2}$

Hence, the correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.
