the sum of all angles in a triangle is 180

Answer:

14.9 dollars

Step-by-step explanation:

1. There are 30 students and if everyone pay the same, it will be 14.9 dollar. Because the total is 447 dolar and if everyone pay equally, then everyone have the same amount. So, 447 dollar divided to 30 student equal 14.9 per student.

2. The essential information is the total cost of money and the amount of student.

3. 30m = 447

/30      /30

m= 14.9 dollar

4. 14.9*30 = 447

Please like if I got it right.

Answer:

4.4 x 3.9 x 8.7 = 149.292

To find an area multiply all given side lengths and make sure to know what shape you are finding the area too because different shapes have different formula's. Parallelograms such as square rectangle or any parallel pair will be just L x W x H or L x W depends if its 2d or 3d

Answer/Step-by-step explanation:

X = ?

Equation = 4(2x - 5) + 15 =1

First:

4(2x - 5) +15 - 15 = 1 - 15

4(2x-5) = - 14

Then

4(2x-5)/4 = -14/4

2x - 5 = -7/2

+5               +5

2x = -7/2 + 5

Simplify

2x = -7/2 + 5

2x = 3/2

Divide

2x = 3/2

2x/2 = (3/2)/2

X = 3/4

hope that helped

Answer:

Replace all occurrences of y with 6x−3 in each equation.

Replace all occurrences of y in 18x−3y=9 with 6x−3 .

18x−3(6x−3)=9

y=6x−3

Simplify 18x−3(6x−3).

9=9

y=6x−3

Remove any equations from the system that are always true.

y=6x−3

Answer: y = 80*

all circles have 360* so we can subtract what we have to get what we want

360 - 110 - 90 - 80 = 80*

Answer:

h=1ft

Step-by-step explanation:

The volume of a cone is:

v=πr^h/3

plug in the values (I am assuming not 1/18π but 1/18×π):

1/18π=  π1/3^2h/3

Get rid of the radius:

1/3^2=1/9

Continue:

π/18= πh/3*1/9= πh/18

Remove the denominators:

π=πh

Divide both sides by π :

h=1

Answer:

Domain: [tex][-1,\infty)[/tex]

Range: [tex](-\infty, 3][/tex]

Decreases over: [tex](-1,-\infty)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -\sqrt{x + 1} + 3[/tex] --- Missing from the question

Solving (a): The domain

To get the domain, the expression under the square root must not be negative.

In other words:

[tex]x + 1 \ge 0[/tex]

Solve for x

[tex]x + 1 -1\ge 0-1[/tex]

[tex]x \ge -1[/tex]

Hence, the domain is:

[tex][-1,\infty)[/tex]

To get the range, we plot the values of the domain in the expression.

[tex]x = -1[/tex]

[tex]f(x) = -\sqrt{x + 1} + 3[/tex]

[tex]f(-1) = -\sqrt{-1+1} +3[/tex]

[tex]f(-1) = -\sqrt{0} +3[/tex]

[tex]f(-1) = -0 +3[/tex]

[tex]f(-1) = 3[/tex]

[tex]x = \infty[/tex]

[tex]f(\infty) = -\sqrt{\infty +1}+3[/tex]

[tex]f(\infty) = -\sqrt{\infty}+3[/tex]

[tex]f(\infty) = -\infty+3[/tex]

[tex]f(\infty) = -\infty[/tex]

So, the range is: [tex](-\infty, 3][/tex]

To get the interval where the function increases or not, we simply plot the graph of f(x).

See attachment for graph.

From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.

This implies that, the graph decreases over the interval [tex](-1,-\infty)[/tex]

Answer:

C = 101

E = 46

Step-by-step explanation:

79 + 134 = 213

180 - 79 = 101 (C+F has to equal 180)

79 + 134 + 101 = 314

360 - 314 = 49 (trapezoids have a total degree of 360)

The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

It is given in the picture that measures the angles of a trapezoid.

It is required to find the other angles.

It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.

We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°

We know in trapezoid:

∠C+∠F = 180° and

∠D+∠E = 180°

For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°

For ∠E = 180° - ∠E  ⇒ 180° - 134° ⇒46°

We have another trapezoid JKLM in which ∠K = 83°

We know in isosceles trpezoid:

∠K = ∠J = 83° and

∠L = ∠M

∠L = 180° - ∠K ⇒ 180° - 83°  ⇒ 97° ⇒ ∠M

Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

=) have a good day

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]

sine-1 = [tex]\frac{17}{42}[/tex]

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

cos-1 = [tex]\frac{16}{25}[/tex]

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50

Answer:

19.8 minutes

Step-by-step explanation:

Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
