How do you get the answer to these two questions? I don’t understand

Your answer is : $2.09

To find this answer you first need to find out how much money Dani spend.The equation for this is (5.72+4.89+7.30=17.91).The last step is to subtract the amount Dani spent by the amount she paid so new equation is (20.00-17.91=2.09)The answer is $2.09

Step-by-step explanation:

Finding b

If we use the given slope and use one of the points to write the equation in point-slope form (y - y₁) = m(x - x₁)), we can rearrange it to find the y-intercept:

Using (4,4)  

                                ⇒  y - 4 =  - 0.5 (x - 4)

                                     y - 4 = - 0.5 x + 2

                                          y = -0.5 x + 6

Calculating 'n' and 'p'

We can find n and p by plugging the points into the newly found equation   y = -0.5 x + 6.

For n using (7, n)

             since  y = -0.5 x + 6

                        n = -0.5 (7) + 6

For p using (3,p)

               since y = -0.5 x + 6

                         p = - 0.5 (3) + 6

                         p = - 1.5 + 6

Checking the answer

We can check the answer we got in two ways:

         Using the points (4, 4) and (7, n) as (x₁, y₁) & (x₂, y₂)   respectively

         The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)  

                               - 0.5  =  (n - 4) ÷ (7 - 4)

                               - 0.5 =  ⁿ⁻⁴/₃          [multiply both sides by 3]

                                - 1.5 = n - 4           [add four to both sides]

                                    n = 2.5     [this matches the value of n we found]

Answer: x = 60°

Step-by-step explanation:

The rest of the question is the attached figure.

Given: A rhombus inside a regular hexagon, work out the angle x.

As shown

ABCDEF is a regular hexagon.

The regular hexagon have 6 congruent angles, and the sum of the interior angles is 720°

So, the measure of one angle of the regular hexagon = 720/6 = 120°

So, ∠F = ∠BAF = 120°

AFEG is a rhombus.

The rhombus have 2 obtuse angles and 2 acute angles.

∠F is one of the obtuse angles of the rhombus = 120°

∠F and ∠FA G are supplementary angles

So, ∠F + ∠FA G = 180°

∴ ∠FA G = 180° - ∠F = 180 - 120 = 60°

∴ x = ∠GAB = ∠BAF - ∠FA G = 120 - 60 = 60°

So, the measure of the angle x = 60°

Answer:

What is the length of an arc cut off?

If θ (in radians) is a central angle in a circle with radius r, then the length of the arc cut off by θ is given by s = r θ (θ is in radians).

Step-by-step explanation:

Length of an Arc = θ × r, where θ is in radian.

Length of an Arc = θ × (π/180) × r, where θ is in degree.

math you do math okay math math math math math

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Hope this helped :)

Answer:

A. None of these

Step-by-step explanation:

The largest perfect square under 100 would actually be 81 (9 x 9)

90 and 99 are not perfect squares and 64 is smaller than 81.

Answer:

a. none of these

Step-by-step explanation:

10 * 10 = 100, so 100 is a perfect square.

The next smaller perfect square is 9 * 9 = 81, but 81 is not in the choices.
