Hi there!

nearest percentage=64%

1.Subtract starting value and final value:

[tex]1599-579=1020[/tex]

2.Divide it by the starting value:

[tex]1020*1599= 0.6378986866791744840525328330206378986[/tex]

3.Multiply the term by 100:

[tex]0.6378986866791744840525328330206378986[/tex]·[tex]100= 63.78986866791744840525328330206378986[/tex]

4.Round the term:

[tex]63.78986866791744840525328330206378986=64[/tex]

Therefore, the decrease of the total 8 years was 64%.

Answer:

64%

Step-by-step explanation:

579 is a 63.789868667917% decrease of 1599.

Percentage of decrease = |1599 - 579|/1599 = 1020/1599 = 0.63789868667917 = 63.789868667917%

Step-by-step explanation:

Answer: C. y equals x

Step-by-step explanation: The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[28] The Egyptians used Egyptian fractions c. 1000 BC. About 4000 years ago, Egyptians divided with fractions using slightly different methods. They used least common multiples with unit fractions. Their methods gave the same answer as modern methods.[29] The Egyptians also had a different notation for dyadic fractions in the Akhmim Wooden Tablet and several Rhind Mathematical Papyrus problems.[citation needed]

The Greeks used unit fractions and (later) continued fractions. Followers of the Greek philosopher Pythagoras (c. 530 BC) discovered that the square root of two cannot be expressed as a fraction of integers. (This is commonly though probably erroneously ascribed to Hippasus of Metapontum, who is said to have been executed for revealing this fact.) In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, and operations with fractions.

A modern expression of fractions known as bhinnarasi seems to have originated in India in the work of Aryabhatta (c. AD 500), Brahmagupta (c. 628), and Bhaskara (c. 1150). Their works form fractions by placing the numerators (Sanskrit: amsa) over the denominators (cheda), but without a bar between them. In Sanskrit literature, fractions were always expressed as an addition to or subtraction from an integer. The integer was written on one line and the fraction in its two parts on the next line. If the fraction was marked by a small circle or cross, it is subtracted from the integer; if no such sign appears, it is understood to be added.

Answer:

Reason 1: To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.

Reason 2: To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

Answer:

45x-6

Step-by-step explanation:

math

way

13 and 7.

Steps

x + x = 20

x - x = 6

2x = 26

x = 13

x = 20 - 13

x = 7

Answer:

13 and 7

Step-by-step explanation:

We have two unknown numbers that add up to 20 and subtract to 6. The question is asking us to find out these two hidden numbers.

Let's form two equations.

x + y = 20

and

x - y = 6

Since we have a positive y and negative y, we can use the addition method to these systems of equations.

   x + y = 20

   x - y = 6

+-----------------

2x = 26

Now isolate x to get x.

Divide both sides by 2 :

x = 13

Now that we have x, we can plug it into the equations.

13 + y = 20

13 - y = 20

So what number will make this true. Use the backwards method :

20 - 13 = 7

Therefore, 13 and 7 are our two numbers.

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Answer:

14.940306992% or 15%

Step-by-step explanation:

To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.

$ 175.90 - $ 149.62 = $26.28

Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.

$26.28 / $175.90

= 0.14940306992

Finally, multiply by 100 and round up to reach a percentage.

Answer:

SA = 126 square cm

Step-by-step explanation:

SA = 2(l · w) + 2(h · w) + 2(l · h)

SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)

SA = 60 + 36 + 30

SA = 126 sq cm  

The surface area of the cuboid box is S = 126 cm²

What is the surface area of cuboid?

A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Let the surface area of cuboid be S

Length of the cuboid = L = 6 cm

Width of the cuboid = W = 5 cm

Height of the cuboid = H = 3 cm

On simplifying , we get

Surface Area = 2 ( LH + LW + HW )

S = 2 ( ( 6 x 5 ) + ( 6 x 3 ) + ( 5 x 3 ) )

S = 2 ( 30 + 18 + 15 )

S = 2 ( 63 )

S = 126 cm²

Hence , the surface area is S = 126 cm²

Answer:

Zeros are x = 1.5, -2.5

Step-by-step explanation:

Given function is,

F(x) = 4x² + 4x - 15

      = 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]

F(x) = 4(x² + 2.5x - 1.5x - 3.75)

      = 4[x(x + 2.5) - 1.5(x + 2.5)]

      = 4(x - 1.5)(x + 2.5)

For 'x' intercepts,

f(x) = 0

4(x - 1.5)(x + 2.5) = 0

x = 1.5, -2.5

Therefore, zeros of the given function are x = 1.5, -2.5.
