Answer

The remaining board piece will be 3 (7/8) feet long

Explanation

Mia's board is 15 (1/2) feet long.

He cut three pieces off the board with each board measuring 3 (7/8) feet long.

The key to this is to first convert the values given in mixed fractions as improper fractions.

3 (7/8) = (31/8)

15 (1/2) = (31/2)

Then, the three pieces each had a length of 3 (7/8)

1 piece = 3 (7/8) feet = (31/8) feet

3 pieces = 3 × (31/8) = (93/8) feet

So, taking this out of 15 (1/2) long board will leave

[15 (1/2)] - (93/8)

= (31/2) - (93/8)

To do that, we need to take the LCM of these two denominators

The remaining board piece will be

(31/8) = 3 (7/8) feet long

For a transformation that involves a reflection over the x-axis, it means the pre-image is reflected across the horizontal line.

For a reflection over the x-axis, the x coordinate remains the same while the y coordinate changes.

The rule that describes a transformation when an image has been reflected over the x-axis is:

(x, y) ==> (x, -y)

Using the pre-image (-x, -y), we have:

(-x, -y) ==> (-x, y)

For a triangle, we have:

A(-x, -y) ==> A'(-x, y)

B(-x, -y) ==> B'(-x, y)

C(-x, -y) ==> C'(-x, y)

Answer:

The angle has measure 72°.

Step-by-step explanation:

Definition:

Two angles are supplementary angles if the sum of their measures equals 180°.

Let x and y be the supplementary angles.

According to the definition above, then,

x + y = 180

We can the above equation for y:

x + y = 180

y = 180 - x

The two angles have measures:

x

180 - x

Now we look carefully at this statement:

"three times the measure of an angle is equal to twice the measure of the angle's supplement"

We translate the above statement into an equation, using x for one angle, and 180 - x for the supplement.

3x = 2(180 - x)

Solve the equation for x.

Distribute 2 on the right side.

3x = 360 - 2x

Add 2x to both sides.

5x = 360

Divide both sides by 5.

x = 360/5

x = 72

The angle has measure 72°.

The range of spectral lines produced during electron transition is determined by the total number of energy levels the electron can jump to.

Spectral lines are bright or dark lines over continuous spectrum which occur due to emission or absorption of energy.

When an electron jumps to or from one energy level to another energy level, spectral lines are produced. The range of spectral lines depends on the number of energy levels available to which the electron can jump. This depends the amount of energy gained/lost by the electron.

Thus, the range of spectral lines produced during electron transition is determined by the total number of energy levels the electron can jump to.

Answer:

[tex]sin(a)=\frac{y}{r}=-\frac{7\sqrt{74} }{74}[/tex]

[tex]cos(a)=\frac{x}{r} =-\frac{5\sqrt{74} }{74}[/tex]

[tex]tan(a)=\frac{y}{x} =\frac{7}{5}[/tex]

Step-by-step explanation:

Given the terminal side of an angle we can calculate the distance between the point given and the origin:

[tex]r=\sqrt{x^2+y^2}[/tex]

[tex]r=\sqrt{|(-5^2)+(-7^2)|}[/tex]

[tex]r=\sqrt{74}[/tex]

y = opposite side

x = adjacent side

r = hypotenuse

Now we have

Notice that the all estimations for each graph are correct.

We know that:

6 < 3r-45 < 36

We want to re arrange the inequations:

Step 1: all terms with an unkown value on one side.

We want to let 3r "be alone" in the middle side:

6 < 3r-45 < 36

6 + 45 < 3r < 36 + 45 [adding 45 in each part]

51 < 3r < 81 [6 + 45 = 51 and 36 + 45 = 81]

Step 2: we want to clear r

51 < 3r < 81

51/3 < r < 81/3 [dividing by 3 all sides]

17 < r < 27 [51/3 = 17 and 81 /3 = 27]

x represents the cost of each bottle of juice. Given that he bought a pack containing 6 bottles of juice, the cost of the 6 pack juice bottles would be $6x

Given that the total cost of a bag of popcorn which costs $2.11 and a 6-pack of juice bottles is $11.41, it means that

2.11 + 6x = 11.41

6x = 11.41 - 2.11

6x = 9.3

x = 9.3/6

x = 1.55

The cost of each bottle of juice is $1.55

Given 3 ( 3 + 4k ) = 45

So, divide both sides by 3

3 + 4k = 45/3

3 + 4k = 15

subtract 3 from both sides

3 + 4k - 3 = 15 - 3

4k = 12

divide both sides by 4

k = 12/4 = 3

Now you can graph it:

In the ratio of 2:6 , Lacey will get 6 cards and Martha will get 18 cards

Total number of cards = 24

Let Lacey gets "x" numbers of cards and Martha gets "y" numbers of cards

Ratio of cards given to Lacey to Martha = 2:6

x:y = 2:6

and we also know that total cards are 24

x + y = 24

x = 24 - y

putting value of x in the ratio,

[tex]\frac{24 - y}{y} = \frac{2}{6}\\[/tex]

cross multiplication,

6(24 - y) = 2y

144 - 6y = 2y

8y = 144

y = 18

Substituting value of y ,

x = 24 - 18

x = 6

Hence , Lacey will get 6 cards and Martha will get 18 cards.

y = 5x − 3 y = 5 x - 3 Substitute −2 - 2 for x x and find the result for y y. y = 5(−2)−3 y = 5 (- 2) - 3

The graph of g(X) = -(x+3)⁴ compares to the parent function of f(x) = x⁴ got shifted 3 units to left and reflected over x-axis.

Translation means shifting , rescaling and reflecting parents function.

Shifting the graph means to move the graph to new location

Scaling means changing it shape

and Reflecting means a mirror image of parent function across either x-axis or y-axis.

here, If we draw graph of both the function you'll see

The parent function f(x) = x⁴ have center as (0,0)

where as Center of function g(x) = -(x+3)⁴ is (-3,0)

means g(x) = -(x+3)⁴ is moves towards the left by 3 units

Using the given ratio, we will see that we can define the proportions to find that:

Sandra gets 12 marshmallows.

Peter gets 18 marshmallows.

We know that Sandra and Peter share a packet of 30 marshmallow eggs in the ratio of 2:3.

We can find the fractions for each person by doing the following steps:

So if we add the two values in the ratio we get 2 + 3 = 5

The ratio is:

Sandra:Peter = 2:3

Then we can write the fractions as:

The fraction of the total number of eggs that Sandra gets is 2/5

The fraction of the total number of eggs that Peter gets is 3/5

Now remember that the total number of marshmallow eggs is 30, then the number that Sandra gets is:

S = (2/5)*30 = 12

And the number that Peter gets is:

S = (3/5)*30 = 18
