Answer 1
2x + 7 = 25
2x = 25-7
2x = 18
2x /2 = 18/2
X = 9

2(9) + 7 = 25
18 + 7 = 25
25 = 25

what is the doors width in simplest form​

Answers

Answer:

x + 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of rectangle = 3x + 6

Width of rectangle = 4x – 1

Width of door =..?

A careful observation of the diagram shows that the door is located along the length of rectangular room.

In a rectangle, two sides are equal. Therefore,

x + door + x = 3x + 6

Making door subject of the above formula, we have:

x + door + x = 3x + 6

door + x + x = 3x + 6

door + 2x = 3x + 6

Subtract 2x from both side

door + 2x – 2x = 3x + 6 – 2x

door = 3x – 2x + 6

door = x + 6

Therefore, the width of the door is x + 6

The term "elevation" is often used to describe the height of a place (such as a city, a mountain, or a valley) compared to sea level. For example, the city of Houston, Texas has an elevation of 105 feet. The surface of the sea has an elevation of 0 feet. Some places are below sea level, so their elevations are negative values. Two towns have different elevations, but when the elevations are used as inputs of , they both produce an output of 25. Why do they produce the same output?

obviously they will produce same output because the elevation of object and image will be same

Please help me asap.

Answers

Answer: < 10, 5 >

===============================================

Let a,b,c,d be scalars.

In general if v and w are two vectors such that

v = <a, b>

w = <c,d>

then the difference of the two vectors is

v - w = <a-c, b-d>

so we subtract the coordinates

-----------------

Using that idea for the given vectors leads to

v = <9, -1>

w = <-1, -6>

v - w = <9 - (-1), -1-(-6)>

v - w = <9+1, -1+6>

v - w = < 10, 5 >

We can calculate the depth d of snow, in centimeters, that accumulates in Harper's yard during the first h hours of a snowstorm using the equation d=5hd, equals, 5, h. How many hours does it take for 1 centimeter of snow to accumulate in Harper's yard? How many centimeters of snow accumulate per hour?

Answers

Answer:

a) 0.2 h

b) 5 cm

Step-by-step explanation:

The given equation is:

[tex] d = 5h [/tex]    (1)

Where:

d: is the depth in centimeters

h: is the time in hours  

a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:      

[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]

Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.  

 

b) The depth in centimeters of snow accumulate per hour is:  

[tex] d = 5h = 5*1 = 5 cm [/tex]

Therefore, 5 cm of snow accumulates per hour.

if this cylindrical vase were filled with water. approximately how much water would it contain? A. 63in^3 B. 126in^3 C. 251in^3 D. 503in^3​

Answers

Answer:

126 in³

Step-by-step explanation:

Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:

Volume of cylinder = πr²h

Where,

r = radius = ½ of d = ½*4 = 2 in

h = height = 10 in

Take π as 3.14

Plug in the values into the formula

Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

30 = ?

Answer:

[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]

Step-by-step explanation:

According to exterior angle theorem:

The measure of the exterior angle is equal to the sum of non-adjacent interior angles.

150 = 120 + <SUT

<SUT = 150-120

the number of diagonals that can be drawn in a opolygon of n sides is 1/2n(n-1)-n. If 230 diagonsaals can be drawn how many sides does the polygon have'

Answers

Answer:

n = 20

Step-by-step explanation:

The number of diagonal that can be drawn in a polygon of n sides is given by :

[tex]D=\dfrac{n(n-3)}{2}[/tex]

If the number of diagonals are 230, then put D = 230 in above formula. So,

[tex]230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0[/tex]

It is a quadratic equation, the value of n is equal to 20.

It means that for 230 diagonal, there are 20 sides of the polygon.

Answers

Answer:

The answer is c

Step-by-step explanation:

You have to do everything backwards,

-9 divide it by 3 to get -3, then add seven to that answer

Answer:

C

Step-by-step explanation:

You can work backward to find out the answer!

Start with -9. Instead of multiplying by 3, you can divide.

-9/3 = -3

Now, instead of decreasing -3 by 7, increase by 7.

-3+7 = 4

Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by the plumbers are listed. Which list shows these lengths in order from greatest to least?

Answers

Answer:

[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]

LCM of the denominators,

2 |  25   11    100   24

2 |  25    11     50    12

5 |  25    11     25     6  

5 |    5     11     5      6  

      1      11      1       6

LCM = 2×2×5×5×6×11 = 6600

[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]

   [tex]=\frac{792}{6600}[/tex]

[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]

    [tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]

[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]

     [tex]=\frac{594}{6600}[/tex]

[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]

    [tex]=\frac{275\pi }{6600}[/tex]

    [tex]=\frac{864}{6600}[/tex]

Now we can arrange these fractions in the order of greatest to least.

[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]

[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]
