This is a ratio based question.

$\frac{492}{500} = \frac{x}{6000}$
$x = 6000 \times \frac{492}{500}$

The right end of this board lines up with the marks halfway between 4 and 5 (Iready) How long is the board?

cupoosta [38]

Answer:

$Halfway = 4.5$

Step-by-step explanation:

Given

4 and 5

Required

Determine the halfway

This is calculated as:

$Halfway = \frac{1}{2}(4 + 5)$

$Halfway = \frac{1}{2}(9)$

Remove bracket

$Halfway = \frac{1}{2} * 9$

$Halfway = 4.5$

Triangle AOC intersects a circle with center O. side AO is 10 inches and the diameter of the circle is 12 inches. What is the le

zvonat [6]

Answer:

$AC=8inches$

Step-by-step explanation:

It is given that triangle AOC intersects a circle with center O, side AO is 10 inches and the diameter of the circle is 12 inches, thus

OC is the radius of the circle and is equal to $\frac{D}{2}=\frac{12}{2}=6 inches$ .

Now, From ΔAOC, using the Pythagoras theorem, we get

$(OA)^{2}=(OC)^{2}+(AC)^{2}$

⇒ $(10)^{2}=(6)^2+(AC)^2$

⇒ $100=36+(AC)^2$

⇒ $64=(AC)^2$

⇒ $AC=8inches$

The minimun point on the graph of the equation y=f(x) is -1,-3. What is the minimum point on the graphof the equation y=f(x-5)

kap26 [50]

The minimum point on the graph of the equation y=f(x-5) is (-6, -3)

<h3>How to determine the minimum?</h3>

The initial minimum is given as:

(-1, -3)

The transformation y = f(x - 5) means that:

(x, y) = (x - 5, y)

So, we have:

(x, y) = (-1 - 5, -3)

Evaluate

(x, y) = (-6, -3)

Hence, the minimum point on the graph of the equation y=f(x-5) is (-6, -3)
