Answer:

A. 22°

E. 15

I. 39°

F. 71°

C. 25.6

H.12.9

K.55°

Step by Step Explanation:

1. $cos^{-1}(52/56)=21.7867893 or 22$ degrees

2. 22sin43=15

3. $tan^{-1}(34/42) or 38.990999404 or 39 degrees$

4. $sin^{-1}(51/54)=70.81186355 or 71 degrees$

5. 20/(tan38)=25.58883264 or 25.6

6. 20sin40=12.85575219 or 12.9

7. $cos^{-1}(26/45)=54.70560532 or55 degrees$

Hope that helps!:)

The rectangle below has an area of x^2-25x 2 −25 square meters and a length of x+5x+5 meters. What expression represents the wid

iris [78.8K]

Answer: x - 5

Step-by-step explanation:

Since, the area of the rectangle = $x^2 - 25=(x+5)(x-5)$

Length of the rectangle = x+5

Let the width of the rectangle = b

Thus, the area of the rectangle = $(x+5)\times b$

⇒ $(x+5)\times b=(x+5)(x-5)$

⇒ $b=\frac{(x+5)(x-5)}{(x+5)}$

⇒ $b=x-5$

Therefore, the expression that shows the width of the rectangle = x-5

An ant can travel at a constant speed of 980 inches every 5 minutes. At this rate, how far can the ant travel in 7 minutes?

Zarrin [17]

Answer:

$1372\: \mathrm{inches}$

Step-by-step explanation:

Since the ant travels at a constant speed, we can set up the following proportion:

$\frac{980}{5}=\frac{x}{7}$ , where $x$ is the distance the ant can travel in 7 minutes.

Solving for $x$ , we get:

$x=\frac{7\cdot980}{5}=\fbox{$1372\:\mathrm{inches}$}$ .
