Step-by-step explanation:

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°

Answer:

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

m= -1

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.

Answer:

y = 15

Step-by-step explanation:

y - 58 = -43

add 58 to both sides

y = 15

Answer:

y = 15

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

y - 58 = -43

Step 2: Solve for y

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Here we see that -43 does indeed equal -43.

∴ y = 15 is the solution to the equation.

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

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
