The measure of the missing angle is 118 degrees

Quadrilateral are figures that have sides and angles

For two parallelograms to be equal, the ratio of the sides must be equal to a constant

Also, all the measure of the angles must be equal. From the given parallelogram, the measure of the angles must be equal that is;

x = 118 degrees

Hence the measure of the missing angle is 118 degrees

Answer: y = -17/14

Step-by-step explanation:

y = -1 -13y - 16

First we must isolate the variable:

y+13y = -1 - 16

Next we must add like terms:

14y = -17

Finally, divide 14 on both sides:

14y/14= -17/14

Answer: y = -17/14

To find the slope of both graph and table, you would have to know the coordinates of both.

Step-by-step explanation:

The formula is: m= y2-y1/x2-x1

Let's say that the graph/table says one point lays on (2,9) and the other is (-3,4). You would use the formula to get your slope.

m= 9-4/(-3)-2

m=5/-5

Step-by-step explanation:

Her z-scores are given as follows:

Due to the higher z-score, she was relatively better on the SAT.

The z-score of a measure X of a distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For the SAT test, the parameters are given as follows:

[tex]X = 680, \mu = 528, \sigma = 117[/tex]

Hence her z-score is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (680 - 528)/117

Z = 1.30.

For the ACT test, the parameters are given as follows:

[tex]X = 27, \mu = 20.5, \sigma = 5.5[/tex]

Hence her z-score is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (27 - 20.5)/5.5

Z = 1.18.

Due to the higher z-score, she was relatively better on the SAT.

Step-by-step explanation:

He needed to subtract before he added, basically from left to right first come first serve.

In ∆ABC,

Angle A = 60°

Angle B = 45°

The measurement of Angle C.

We know that the sum of all the interior angles of a triangle is 180°.

Angle A + Angle B + Angle C = 180°

By putting the respected values, we get

60° + 45° + Angle C = 180°

or, 105° + Angle C = 180°

By transposition method, we get

Angle C = 180° - 105°

Angle C = 75°

The measurement of Angle C is 75°

The time when the two airplanes would have the same altitude is 8 minutes. The altitude would be 21,600 feet.

The equation that can be used to represent the altitude of the descending plane is: feet above the ground - (rate of descent x number of minutes)

46,400 - (3100 x t)

The equation that can be used to represent the altitude of the ascending plane is: rate of ascent x number of minutes

2700 x t

Where t is the number of minutes

When both airplanes are of the same altitude, the above equations will be equal: 2700t = 46,400 - 3100t

In order to determine the value of t, take the following steps:

Combine similar terms: 2,700t + 3,100t = 46,400

Add similar terms : 5,800t = 46,400

Divide both sides by 5,800 : t = 46,400 / 5,800

t = 8 minutes

Altitude = 2700 x 8 = 21,600 feet
