Answer:

P = 42 cm

Step-by-step explanation:

The perimeter (P) is the sum of the 4 sides of the rectangle with opposite sides being congruent.

Given width = 7 cm then length = 2 × 7 = 14

P = 7 + 7 + 14 + 14 = 42 cm

What is the approximate value of x in the diagram below
Anon25 [30]

Answer:

x = 8 cm

Step-by-step explanation:

The first step in solving this problem is to determine which trig function applies.  The diagram shows that this triangle is a right triangle, that side x is opposite the 25-degree angle, and that the hypotenuse has a length of 18 cm.  

The sine function of an angle Ф is defined as the ratio of the opposite side to the hypotenuse.  In this case, sin Ф (or sin 25 degrees) equals x/(18 cm).

We need to determine the value of x.  Adapt the above equation to this particular situation:  sin 25 degrees = x/(18 cm).

To solve for x, multiply both sides of the most recent equation, above, by (18 cm).  The following results:  (18 cm)(sin 25 degrees) = x.

Next, use a calculator to find the value of sin 25 degrees:  It is 0.4226.

Then the desired value of x is (18 cm)(0.4226), or x = 7.61 cm.  This should be rounded off to x = 8 cm to reflect the level of accuracy of the given 18 cm.

Pretend you are coaching a sports team—you pick the sport. What are some ways you would use matrices on the job?
gayaneshka [121]
<span>A matrix is basically a table of columns and rows. One way to use an array is to tabulate information concerning two variables, for example, sizes of shoes and person's height, or price of different kinds of vegetables over 12 months, etc. So for your problem, think of two variables that you can tabulate in your sports team. If you are out of ideas, read the sports page.</span>

Solve the equation.<br><br> 20 = –d + 16
My name is Ann [436]

Answer:

<h2>d = -4</h2>

Step-by-step explanation:

20 = -d + 16          <em>subtract 16 from both sides</em>

20 - 16 = -d + 16 - 16

4 = -d               <em>change the signs</em>

-4 = d ⇒ d = -4

A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses
laila [671]

Answer:

Probability of missing two passes in a row is 0.08.

Step-by-step explanation:

Event E = A football player misses twice in a row.

P(E) = ?

Event X = Football player misses the first pass

P(X) = 0.4

Event Y = Football player misses just after he first miss

P(Y) = 0.2

Both the events are exclusive so the probability of occuring of these two events can be calculated by the formula:

P(E) = P(X).P(Y)

P(E) = 0.4*0.2

P(E) = 0.08
