Answer: The value of RIG is 59 degrees and the value of ZIM is 31    degrees.

Given: Lines AM,ZG, RI are parallel

angle RIM = 90 degree and lines AM,ZG and RI intersect at point I.

Concept: All angles on the same line make an angle of 180 degree.

Since all angles on a line make an angle sum of 180 degree

So using the above property of straight lines,

Angle RIA + angle RIG + angle GIM = 180 degree

90 + 4z+7 +x+2 = 180

4z+x = 81  ----- (1)

Angle AIZ + angle AIR + angle RIG = 180 degree

3x-56 + 90 + 4z+7=180

3x +4z =139 ----- (2)

3(81-4z) +4z =139

243 -8z =139

z=13

x= 81- 52 = 29

A) In one hour  Graham drove 33 3/4 miles

B) To drive one mile Grahman will take 4/127 hours

a) change into improper fractions

42 1/3 = 127/3

1 1/3 = 4/3

he takes 4/3 hours to drive 127/3 miles

in one hour he will drive 127/3 × 3/4 = 127/4 = 33 3/4 miles

So in 1 hour he will drive 33 3/4 miles

b) he covers 127/3 miles in 4/3 hours

to cover 1 mile he will take = 4/3 × 3/127 = 4/127 hours

The side of one side of the square is determined as: 8.5 meters.

A square is a quadrilateral shape that has four sides that have the same length and four interior angles that are right angles (90 degrees).

The perimeter of a square is the sum of all the sides of a square which can be calculated using the following formula given as,:

Perimeter = 4(s), where s represents the length of one side of the square.

We are given that:

Perimeter of the square = 34 meters

Therefore:

34 = 4(s)

Divide both sides by 4

34/4 = 4(s)/4

8.5 = s

s = 8.5 m

The will have to work for 3 weeks in order to save money for down payment of car.

Unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given in the question is a story of john works at the mall, 20 hours a week and makes $8.50 an hour. He is saving for a car and needs a down payment of $500.

Assume that he has to work 'x' number of weeks for down payment.

For 1 hour, John earns → $8.50

Number of hours he work in the mall per week → 20 hours

Amount of money collected in one week → $8.50 x 20 = $170

Money needed for down payment → $500

In 1 week, John earns → $170

So, he earns $1 in → 1 / 170 weeks

Therefore, he will earn $500 in →

(1 / 170) x 500 = 2.94 = 3 weeks (approx.)

Therefore, he will have to work for 3 weeks in order to save money for down payment of car.

The solutions to the given quadratic equation 4x² - 4x - 1 = 0 are x = ( 1 - √2 )/2,  ( 1 +√2 )/2.

A quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the equation in the question;

4x² - 4x - 1 = 0

Compared to the standard form ax² + bx + c = 0

Plug these values into the quadratic formula above.

x = (-b±√(b² - 4ac)) / (2a)

x = (-(-4) ± √((-4)² - ( 4 × 4 × -1 ))) / (2 × 8)

x = ( 4 ± √( 16 - ( -16) ) / (8)

x = ( 4 ± √( 16 + 16) ) / (8)

x = ( 4 ± √( 32) ) / (8)

32 can be written as 4²×2

x = ( 4 ± √( 4²×2 ) ) / (8)

x = ( 4 ± 4√2 ) / (8)

x = ( 1 ± √2 ) / 2

x = ( 1 - √2 )/2,  ( 1 +√2 )/2

Therefore, the solutions to the given quadratic equation 4x² - 4x - 1 = 0 are x = ( 1 - √2 )/2,  ( 1 +√2 )/2.

Answer: The amount less will be with held weekly for federal income tax is $40.65.

Step-by-step explanation:

Given data,

Nico Joven presently earns $348.40 per week.

The amount of money deducted from federal income tax is:

                          = $348.40/2

                          = $174.20

He claims himself and his mother as allowances.

He is single. He is to get a new job classification, which will result in a 15% increase in pay.

The increase in pay will be:

                           = 15% × $348.40

                           = $52.26

After his marriage, he will claim his wife, himself, and his mother as allowances.

The new salary will be the addition which is $400.66.

The new money with held will be:

                            = $400.66/3

                            = $133.55

The amount less withheld will be:

                      = $174.20 - $133.55

                      = $40.65

in this given sum we need to find how many additional pendents kelsey need to make and sell to make profit .  The information that are give in the sum

she has to pay $200 for the rent

materials for each pendant is $ 7.8 .

for 10 pendants  the total will be 10*7.8 = $78

Therefore she will spend a total of $(78 +200) = $278

So to make a profit the amount of pendants kelsey make multiply it by 13.50 should be greater than the totall amount she spend in making 10 pendants $278 added to the number  of pendants she makes multiply by 7.8 that is the total cost

let the no. of pendants she need to make be x

we can write then above explanation as

13.50x >278 + 7.8x

=> 13.5x - 7.8x > 278 +7.8x - 7.8x      [subtracting 7.8x on both side]

=> 5.7x > 278

=> x > 278/5.7 = 48.77 = 49 (approx.)

b) 0.3% of people has an IQ score less than 43 or greater than 157.

c) 16% of people has an IQ score greater than 119.

Step-by-step explanation:

The order of expressions from the least to greatest is [tex]\sqrt{3}[/tex], [tex]\sqrt{pie}[/tex] and 2

In order to find the value of these given expressions, we will have to convert them into a standard form, therefore we will find the value of these expressions by removing the root and finding its actual value

Value of 2 will remain the same as it is already in standard form

Value of [tex]\sqrt{3}[/tex] in standard form = 1.732

Value of [tex]\sqrt{pie}[/tex] in standard form = [tex]\sqrt{3.1459}[/tex] = 1.77

No ordering these expressions we find that 2 is the greatest, followed by 1.77 and 1.732

Answer:

Angle RIG is 69

angle ZIM is 126.5

Step-by-step explanation:

angle AIZ and ZIP

x + 3x - 56 = 90

    4x - 56 = 90

            4x = 90 + 56

            4x/4 = 146/4

                x  = 36.5

Plugin the value of x in (3x -56)

      3x - 56

     (3(36.5) - 56)

     (109.5 - 56) =  53.5

       Angle AIZ = 53.5

Angle RIG is 4z + 7. Convert the letter x in (x + 2)  to Z and solve for z

4z + 7 + z + 2 = 90

         5z + 9 = 90

                5z = 90 - 9

                5z/5 = 81/5

                   z = 16.2

                        Z + 2

                      16.2 + 2 = 18.2

           Angle GIM is 18.2 degrees

  Plugin the the value of z into 4z + 7 for angle RIG

By solving a system of equations we conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.

First, let's define the variables we will use to solve this problem:

We know that they want to get 55 ounces, then:

x + y = 55

And the concentration of these 55 ounces must be 16%, then we can write other equation:

0.1*x + 0.2*y = 0.16*55

Then we have a system of equations:

x + y = 55

0.1*x + 0.2*y = 0.16*55

Isolating x on the first equation we get:

x = 55 - y

Now we can replace that in the other equation so we get:

0.1*(55 - y) + 0.2*y = 0.16*55 = 8.8

Now we can solve this for y.

5.5 - 0.1*y + 0.2*y = 8.8

5.5 + 0.1*y = 8.8

y = (8.8 - 5.5)/0.1 = 33

Then the value of x is:

x = 55 - y = 55 - 33 = 22

We conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.

ex: your numbers are 50, 55,and 90

median = 55 (as it's the middle number)

mean = 65 ( 90+ 55+ 50 / 3)

so median is the lower number, meaning it would be better in this** case.

The military drone must ascend 12250 from its position of 3500ft above sea level feet so that it is vertically in the middle of the plane and the submarine.

To solve this problem we need to understand the concept of sea-level. The sea-level is defined as the average height of all water bodies of the earth. Below sea level is effectively taken as negative length and above sea -level is taken as positive length.

Let us consider the drone will have to ascend x feet to be vertically in between the plane and the submarine.

The submarine is 3500 feet below the sea level.

The plane is 35000 feet above the sea level.

Now we know that the drone is at a height of 3500 feet above the sea level.

Total distance between the drone and the ship=35000-(-3500)=38500ft

Middle point of the two=38500/2 = 19250 feet from the plane

Height above sea level for the drone should be=35000-19250=15750 ft

height of the drone=3500ft

The drone should ascend=15750-3500=12250 feet
