Answer:

length= 35 feet and width= 10 feet

Step-by-step explanation:

You are given the perimeter of the rectangular deck is

90 feet.

2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5

Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.  

2x (4 x width - 5) + 2 x width =90

Distribute the 2 though

8 x width - 10 + 2 x width = 90

Combine like terms with width.

10 x width - 10 = 90

Add 10 to both sides.

10 x width = 100

Divide both sides by 10 width = 100

Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5

Length = 4 x 10 - 5

Length = 40 - 5

Length = 35

The frequency for 2 to 7 is 3

The frequency for 8 to 13 is 4

The frequency for 14 to 19 is 2

The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Answer:

1) Not Similar. 2/6 does not equal 6\12

2) Yes. 5/3 = 15/9

3)Yes. 10/30=8/24

4) Not Similar. 13/16 does not equal 16/21.

5) Not Similar. 28/48 and 42/36 do not reduce to the same value.

6)No. The angles are not the same.

Step-by-step explanation:

Ask yourself, is it proportional? Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

In other words, ifthe corresponding sides reduce down to the same value, they are similar.

Step-by-step explanation:

Answer:

Step-by-step explanation:

First change 4 3/10 to 4.3. Then you change 4.3 + -6.2 to 4.3 - 6.2.

Then you do 4.3 - 6.2 and you should get - 1.9.

Answer:

The answer is (-1.9)

Step-by-step explanation:

4 3/10 = 4 × 10 + 3/10 = 43/10 = 4.3

Now,

4.3 - 6.2 = -1.9

Thus, The answer is (-1.9)

Answer:

Derions answer is not correct becuase 500 x 0.015=7.5 inches.  If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.  

If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Step-by-step explanation:

given,

dollars saved by Sam = 6x + 8

dollars saved by Teresa = 14x + 32

total money = $220

a/q

money saved by,

sam + Teresa = $220

so,

6x + 8 + 14x + 32 = 220

20x + 40 = 220

20x = 220 - 40 = 180

x = 180/20 = 9

x = 9

now,

money saved by,

Sam = 6x + 8 = 6(9) + 8 = $62

Teresa = 14x + 32 = 14(9) + 32 = $158

therefore,

money individually saved by Sam is $62 and by Teresa $158.

Answer:

1000000000000

Step-by-step explanation:

1000000x1000000=1000000000000

The solution of the expression 1000000 x 1000000 in exponential form is  [tex]10^{12}[/tex].

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

Example = 4y, 3x+4.

The way of writing or expressing a number in powers is called exponent.

Example: [tex]3^2[/tex]

Here, 3 is the base and 3 is the power.

The given expression can be written in the index  or exponential form as:

1000000 x 1000000 = [tex]10^6 \times 10^6[/tex]

Since, the given exponent has the same base.

So, using the law of exponent, it can be written as:

[tex]a^m + a^n = a^{(m+n)[/tex]

[tex]10^6 \times 10^6 = 10^{(6+6)}[/tex]

                  = [tex]10 ^{12}[/tex]

Thus, the solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].
