Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

To find the value of x when y = 24, we must first find the relationship between them

<h3> $y \: \: \alpha \: \: \frac{k}{ \sqrt{x} }$ </h3>

where k is the constant of proportionality

when

x = 16

y = 2

Substitute the values into the above formula and solve for k

That's

Cross multiply we have the answer as

k = 8

So the formula for the variation is

Now when y = 24

We have

Square both sides

We have the final answer as

Hope this helps you

A photograph has a length that is inches longer than its width, x. So its area is given by the expression square inches. If the

Kitty [74]

Answer:

The width is 10 inches.

x(x + 3) = 70

x² + 3x = 70

Subtract 70 from both sides.

x² + 3x - 70 = 0

Factor the trinomial

(x - 7)(x + 10) = 0

Set each equal to zero.

x = - 7, - 10

Distance can't be negative so x = 7 is the right one. Now we plug in for the length (x + 3)

x + 3

7 + 3

A cylindrical garbage can has a radius of 2.8ft and holds 86.21 cubic feet of trash. whats the height?

Crazy boy [7]

Answer:

Correct choice is A

Step-by-step explanation:

The volume of the cylinder can be calculated using formula

$V=\pi r^2 h,$

where r is the base circle radius and h is the height of the cylinder.

In your case, $V=86.21\ ft^3,\ \ \ r=2.8\ ft,$

then

$86.21=\pi\cdot (2.8)^2\cdot h,\\ \\h=\dfrac{86.21}{7.84\pi}\approx \dfrac{86.21}{7.84\cdot 3.14}\approx 3.5\ ft.$
