What are the percentages?

Percentage is the fraction of a number expressed as a number out of 100. In order to convert a number of fraction to percentage, multiiply by 100. The sign that is used to represent percentage is %.

Percentage spent on transportation = (576 / 4800) x 100 = 12%

Percentage spent on Property tax = (528 / 4800) x 100 = 11%

Percentage spent on utilities = (432 / 4800) x 100 = 9%

Percentage spent on food = (960 / 4800) x 100 = 20%

Percentage spent on mortgage payment = (1440 / 4800) x 100 = 30%

Percentage spent on entertainment = (384 / 4800) x 100 = 8%

Percentage spent on miscellaneous = (480 / 4800) x 100 = 10%

Thanks, by neve124

It is to be noted that by the proof given below, the attached shape ABCD is a kite.

What is a kite in Euclidean Geometry?

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equivalent angles and two pairs of adjacent equal-length sides as a result of its symmetry.

The proof is as follows:

AB = AD [Given]

∠ADC = 115°   [Angles on a Straight line]

That is 180 - 65 = 115°

∠BCD = 20°    [Vertical Angles are equal]

∠ABC = (360 - (20+115+110))

= 115°              [Angles in a quadrilateral]

Hence,

ABCD = Kite    [Definition of  a Geometric Kit]

That is

It two equivalent angles (∠ABC and ∠ADC)It also has two pairs of adjacent equal-length sides (that is  |AD| ≈ |AB|.

Answer:

b x 8 = 40 and 40 / 8 =b

Step-by-step explanation:

well, 8 charms makes one bracelet, so add up 8 until you run out of charms:

8 8 + 8 = 16 16 + 8 = 24 24 + 8 = 32 32 + 8 = 40

We only have 40 charms, so we can make 5 bracelets!

Now, plug this number (5) back into the equations:

b x 8 = 40

(5) x 8 = 40

40 = 40

this checks out!

40 - 8 = b

40 - 8 = (5)

32 = 5

32 does not equal 5, so this equation doesn't work.

40 / 8 = b

40 / 8 = (5)

5 = 5

This equation works :)

b + 8 = 40

(5) + 8 = 40

13 = 40

13 does not equal 40, so this is also a bad equation..

since b x 8 = 40 and 40 / 8 = b both produced the right results, we know those two are our answers!

Paula measured the auditorium and made a scale drawing. The stage, which is 56 feet long in real life, is 84 inches long in the drawing. What scale did Paula use?
3 inches= blank feet

Answers

Based on the number of inches in the drawing and the number of feet in real life, the scale that Paula used was 3 inches = 2 feet

What scale did Paula use?

The scale that Paula used was such that the stage was 56 feet long in real life but 84 inches long on the drawing.

The scale can therefore be shown by the ratio:

56 feet : 84 inches

If the number of inches is 3 then the number of feet in the scale would be:

56 feet : 84 inches

x feet    :  3 inches

Cross-multiplying gives:

84x = 168

x = 168 / 84

x = 2 feet

Answers

When a person is 3 feet from a street light, the length of the shadow grows at a rate of 4 feet per second.

See the figure that illustrates the in question statement, attached.

making use of the related triangle theorem;

4/y = 12/x+y

Cross multiply

4(x+y)=12y

4x+4y = 12y

4x=8y

x/y =2

x=2y

Divide the two sides of the equation by t, where dx/dt = 2 dy/dt. The speed at which the person is walking away from the street light is expressed as dx/dt 

The growth rate of the shadow's length is measured by the ratio dy/dt.

Given that dx/dt = 8ft/s

by solving,

dy/dt = 4 ft/s

Hence the rate at which the length of the shadow growing when the person is 3 feet from the street light is 4ft/s

G(x)=|x-2|




How do u solve this?

Answers

what are you looking for ?
First set x-2 to be 0. The result (x) would be 2. Then, try any number that is below 2, let’s say x=0. Substituting G(0) = |0-2|, you would get that y = 2. This is when you can draw a line starting from point P(2, 0) (for when y = 0) and passing through point P(0, 2) (for when x = 0). Now try any number for x bigger than 2, let’s say 4. Substituting that into the function, you get G(4) = |4-2|, which means y = 2. Now, you can draw a final line starting from P(2, 0) (for when y = 0), and passing through P(4, 2) (for when x = 4). If the answer wanted to show a graph with this configuration, you'd get something in the lines of a V shape, with its point of convergence for y being 0 (I’m talking about the point when the 2 lines converge).

What is x in this equation -7(x+-2)=-63

Answers

To find the value of x , we need to simplify it.

The given equation is [tex]\fbox{-7(x+(-2))=-63}[/tex]

Multiplying -7 with x and -2

=> -7x+14 = -63

Transposing 14 to right hand side with change in sign,

=> -7x = -63-14

=> -7x = -77

Canceling ‘-‘ on both sides ,

=> 7x = 77

=> x=[tex]\frac{77}{7}[/tex]

=> x = 11

Hence the required value of x is [tex]\fbox{x= 11}[/tex].

Round 34,582 to the nearest thousand.

Answers

Answer:

35000

Step-by-step explanation:

So the number is 34582

now look at the hundreds

if it is 5 or over then we add a thousand to and subtract what ever the lower than thosand

and in this case it is 5 so we round UP

and now we have 35000

The answer is 35,000.

To round to the nearest thousand, we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.

Since in this case the last three digit consists of 582 which is greater than 500 so we round the thousands digit up i.e. from 4 to 5 in this case.
