Answer:

[tex]first \: answer \: is \: correct \: \\ [/tex]

Answer:

Here

Step-by-step explanation:

length = x

width = 2x - 3

Perimeter = 2length + 2 width

2x + 2(2x - 3) = 42

2x + 4x - 6 =42

6x - 6 = 42

Add 6 to both sides

6x = 48

Divide both sides by 6

x = 8

Length = 8 inches

Width = 2(8) - 3 = 16-3 = 13 inches

Answer:

c

Step-by-step explanation:

Given:

The function is:

[tex]g(a)=\dfrac{8-a}{4}[/tex]

To find:

The difference quotient of the function.

Solution:

Formula for difference quotient of the function f(x) is:

[tex]DQ=\dfrac{f(x+h)-f(x)}{h}[/tex]

We have,

[tex]g(a)=\dfrac{8-a}{4}[/tex]

The difference quotient of the function g(a) is:

[tex]DQ=\dfrac{g(a+h)-g(a)}{h}[/tex]

[tex]DQ=\dfrac{\dfrac{8-(a+h)}{4}-\dfrac{8-a}{4}}{h}[/tex]

[tex]DQ=\dfrac{\dfrac{8-a-h-8+a}{4}}{h}[/tex]

[tex]DQ=\dfrac{-h}{4h}[/tex]

[tex]DQ=-\dfrac{1}{4}[/tex]

Therefore, the difference quotient of the given function is [tex]-\dfrac{1}{4}[/tex].

Answer:

B. Period 1 had scores that were less spread out around the mean than

Period 2

Step-by-step explanation:

Because the standard deviation of Period 2's scores is greater than that of Period 1's, the test scores for Period 2 are going to be more spread out than Period 1's test scores. B is the most logical choice in this case.

Answer:

The answer is 3 feet.

Step-by-step explanation:

First, the height is 7 right. Then take away 1 foot since is said 1 foot more than twice the width. Then divide by 2 meaning twice. Meaning 7-1=6 6/2=3. There you go! Hope these formulas helped!

Answer:

3 feet

Step-by-step explanation:

To relate the height and width of the door, we can write an equation, which is derived from what is given in the problem. If we define w as the width and h as the height, the words, "1 foot more than twice the width" can translate to:

2w + 1, and this is equal to the height, so

2w + 1 = h

Now, we are given the height is 7. We substitute 7 where the height, h, is.

2w + 1 = 7

We can subtract 1 from both sides and divide by 2 to isolate x:

2w + 1 = 7

      -1     -1

2w = 6

w = 3 - the width is 3 feet

You solve using Pemdas, doing the (-8/4) first, and then doing (-6)(2)

The answer is the two values added together.

Answer:

The sum of the series is: 749

Step-by-step explanation:

Given

[tex]a_1 = 8[/tex]

[tex]a_{14} = 99[/tex]

[tex]n = 14[/tex]

Required

The sum of the series

This is calculated using:

[tex]S_n = \frac{n}{2}[a_1 + a_n][/tex]

Substitute 14 for n

[tex]S_{14} = \frac{14}{2}[a_1 + a_{14}][/tex]

[tex]S_{14} = 7[a_1 + a_{14}][/tex]

Substitute values for a1 and a14

[tex]S_{14} = 7[8 + 99][/tex]

[tex]S_{14} = 7*107[/tex]

[tex]S_{14} = 749[/tex]

Answer:68

Answer:

7

Step-by-step explanation:

Let the missing number of the data be x.

[tex] \because mean = \frac{3 + 4 + x + 7 + 2 + 1}{6} \\ \\ \therefore 4 = \frac{17 + x }{6} \\ \\ \therefore 4 \times 6 = 17 + x \\ \\ \therefore 24 - 17 = x \\ \\\therefore x = 7[/tex]

Thus, the missing number of the data is 7.

Answer:

[tex]625ft^{2}[/tex]

Step-by-step explanation:

First get the l by finding the square root of the area

[tex]\sqrt{25}[/tex] = 5cm

since             1cm = 5ft

what about   5cm =?

(5cm×5ft)/1cm

l=25ft

area of the actual floor is l × l

[tex]25^{2}[/tex]

which is [tex]625ft^{2}[/tex]

Answer:

  920 square feet

Step-by-step explanation:

The surface area is the sum of the areas of the different surfaces of the solid. This solid has 5 surfaces: 2 triangular bases and 3 rectangular faces.

The area of a triangle is given by the formula ...

  A = 1/2·bh . . . . . where b is the base of the triangle, and h is its height

The dimensions shown on the "front" of the figure tell you the triangle has a base of 15 ft and a height of 8 ft. Its area is ...

  A = (1/2)(15 ft)(8 ft) = 60 ft²

__

The rectangular faces all have a width of 20 ft. So, the sum of their rectangular areas will be that width multiplied by the sum of their lengths. We call this the "lateral area" of the prism.

  lateral area = (base perimeter) × (prism width)

  = (8 ft + 15 ft + 17 ft) × (20 ft) = 800 ft²

The sum of the areas of the two base triangles and the lateral area is the total surface area of the figure:

  total area = 2×60 ft² + 800 ft²

  total area = 920 ft²
