Answers

Answer 1

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

The lines represented by the equations y = 1x – 5 and 3y + x = -15 are .....

Solve for y in 3y + x = -15.

[tex]3y + x = -15 \\ \frac{ - x = - x}{3y = - x - 15} \\ \\ \frac{3y = - x - 15}{3 \: \: = \: \: \: \: \: \: \: \: \: 3} \\ y = - \frac{1}{3}x - 5[/tex]

[tex]y = - \frac{1}{3}x - 5 \: and \: y = 1x - 5[/tex]

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of the tree is 39.1027 feet.

What is Tangent (Tanθ)?

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The Base is the adjacent smaller side of the angle θ.

Tan(70°) = Height of the tree/Shadow of the tree

Tan(70°) = Height of the tree/ 32 feet

Height of the tree = 39.1027 feet

Hence, the height of the tree is 39.1027 feet.

Joshua and Brandon buying a pizza for their math class. They will spend $77. Joshua will pay six times more then Brandon. How much will Joshua pay?

Answers

Answer:

$66

Step-by-step explanation:

For this problem, we will simply write two equations to solve how much each person will pay.

Let x represent the amount of dollars joshua pays and y represent the amount of dollars brandon pays.  Then we can say the following:

x + y = 77

x = 6y

Using these two equations, we can solve for how much Joshua will pay.

x + y = 77

6y + y = 77

7y = 77

y = 11

x + y = 77

x + 11 = 77

x = 77 - 11

x = 66

Hence, Joshua pays $66 and Brandon pays $11.

If the scale factor of Figure A to Figure B is 7:2, find the perimeter of Figure A.

Answers

Answer:

122.5 units

Step-by-step explanation:

The proportion would be between the perimeters and the given ratio:

7/2 = p/p

Where P is the perimeter of the bigger figure and p is the perimeter of the smaller figure.

Remember that the perimeter is the sum of all sides, using all given values and solving for P, we have

7/2=P/9+5+9+12

7/2=P/35

7(35)/2=P

P=245/2=122.5

Therefore, the perimeter of Figure A is 122.5 units.

First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.
