A rectangle measures 16 cm by 4 cm. It has the same area as a square. Find the perimeter of the square.

Elis [28]

ok ... in this situation... we need to find the area of the rectangle first as it is equal to the area of square .

so .... area of rectangle = l×b= 16×4

= 64 ∴area of square = 64

area of square = s×s

∴to find one side of the square ... we need to find the root of 64 = 8

∴one side = 8

now : perimeter of square : 4 × sides = 4 × 8 = 32 ║

HELP ASAP 20 points Question 12 Multiple Choice Worth 1 points)

ryzh [129]

Answer:

Step-by-step explanation:

To find the angle of depression we use cosine

cos∅ = adjacent / hypotenuse

37.4 is the hypotenuse

17.8 is the adjacent

$\cos(x) = \frac{17.8}{37.4} \\ \\ x = { \cos( }^{ - 1} \frac{17.8}{37.4} ) \\ \\ x = 61.6$

Hope this helps you

If a ship's path is mapped on a coordinate grid, it follows a straight-line path of slope 3 and passes through point (2, 5).

Ugo [173]

Part A: The equation of the ship's path is $y=3x-1$

Part B: The two ships sails perpendicular to each other.

Explanation:

Part A: It is given that $m=3$ and point (2, 5)

Substituting these in the slope intercept form, we have,

$y-y_{1}=m\left(x-x_{1}\right)$

$\begin{aligned}y-5 &=3(x-2) \\y-5 &=3 x-6 \\y &=3 x-1\end{aligned}$

Thus, the equation of the ship's path in slope intercept form is $y=3x-1$

Part B: The equation of the second ship is $x+3 y-6=0$

Let us bring the equation in the form of slope intercept form.

$\begin{aligned}3 y &=-x+6 \\y &=-\frac{1}{3} x+2\end{aligned}$

Thus, from the above equation the slope is $m=-\frac{1}{3}$

To determine the two ships sailing perpendicular to each other, we have

$m_{1} \times m_{2}=-1$

where $m_{1}=3$ and $m_{2}=-\frac{1}{3}$

$\begin{aligned}3 \times-\frac{1}{3} &=-1 \\-1 &=-1\end{aligned}$

Since, both sides of the equation are equal, these two ships sails perpendicular to each other.
