the length of a rectangle exceeds its width by 17 inches, and the area is 18 square inches. what are the length and width of the
dimaraw [331]

The length and width of the rectangle are 18 in and 1 in, respectively.

<h3>Quadrilaterals</h3>

There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid, and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, in a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

The area of a rectangle can be found for the formula : b*h, where b = base and h =height.

For this question, the length exceeds its width by 17 inches - L=W+17. Here, the length is the base and the width is the height. Thus,  from the value of area given, you can find the values of the length and width of the rectangle.

A=b*h

18=(W+17)*W

18=W²+17W

W²+17W-18=0

Solving this quadratic equation, you have:

w_{1,\:2}=\frac{-17\pm \sqrt{17^2-4\cdot \:1\cdot \left(-18\right)}}{2\cdot \:1}

w_{1,\:2}=\frac{-17\pm \:19}{2\cdot \:1}

w1=1 and w2= -18

For dimensions, only positive numbers must be used. Then, the width is equal to 1 inch.

As, the area (l*w) is 18 in², see.

18=l*w

18=l*1

l=18 in

A rectangular board has a perimeter of 28 feet. if the length is twice the width minus 1 foot, then what is the length of the bo
Westkost [7]
P = 2(L + W)
P = 28 
L = 2W - 1

28 = 2(2W - 1 + W)
28 = 2(3W - 1)
28 = 6W - 2
28 + 2 = 6W
30 = 6W
30/6 = W
5 = W ....width is 5 ft

L = 2W - 1
L = 2(5) - 1
L = 10 - 1
L = 9 <=== length is 9 ft

Find the cardinal number for the given set.
iris [78.8K]

Answer:

The cardinal number is 12

Step-by-step explanation:

The cardinal number of a set represents the number of distinct elements of the set. That means for this exercise the goal is to identify the total number of elements of the set.

First step. Identifying the elements of the set.

If we look at the sequence 9, 11, 13, ... , 31, we have an arithmetic sequence a_n, so we can start by finding the common difference d.

d = a_{n+1}-a_n

That means we can pick any 2 consecutive terms and find the subtraction of them, so we can pick for example 9 and 11, thus we get

d= 11-9\\d=2

Second step. Finding the number of terms of the arithmetic sequence.

Now to find the number of elements n of that sequence, we can look at the last number of the sequence on this case it is 31, and we can use the formula for the nth term, that is

a_n=a_1 + d(n-1)

Replacing the last term a_n = 31 and the initial term a_1=9, will give us

31=9+2(n-1)

From there we can solve for n, by moving first that 9 to the other side.

31-9=2(n-1)\\22=2(n-1)

Then we can divide both sides by 2, and lastly add by 1.

\cfrac{22}{2} = n-1  \\11 = n-1\\\boxed{n= 12}

Thus since the sequence has 12 elements, we know that the cardinal number of the set is 12.
