[Help Asap, Will Mark Brainliest If Correct!] Find the area of the figure. (Sides meet at right angles.)

Answer:

31.2

Step-by-step explanation:

Divide 4/15= 2.66

12x2.6= 31.2

This might be wrong..

Answer:

y=x-6

5x-2y=-30

5x-2(x-6)=-30

3x+12=-30

3x=-42

x=-14

y=x-6

y=-14-6

y=-20

(-14, -20)

Answer: [tex]6, 9\ \text{units}[/tex]

Step-by-step explanation:

Given

The Sum of length and width is [tex]15\ units[/tex]

length is 3 units more than the width

width is [tex]x[/tex]

length is [tex]x+3[/tex]

Their sum is 15

[tex]\Rightarrow x+x+3=15\\\Rightarrow 2x=12\\\Rightarrow x=6\ \text{units}[/tex]

Length is [tex]x+3=9\ \text{units}[/tex]

Width is  [tex]x=6\ \text{units}[/tex]

Answer:

y= 69x + 356

Step-by-step explanation:

y= 69x + 356

It goes 69 feet per second hence the 69x and it starts 356 feet in the air

The height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t^2 + 69t + 365.

Assuming that the acceleration due to gravity is -32 feet per second squared (neglecting air resistance), we can use the following kinematic equation to describe the height of the stone as a function of time:

h(t) = -16t²+ vt + h₀

where:

h(t) is the height of the stone above the ground at time t

v is the initial velocity of the stone (69 feet per second, in this case)

h₀ is the initial height of the stone (365 feet above the ground, in this case)

Substituting the values of v and h0, we get:

h(t) = -16t² + 69t + 365

Therefore, the height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t² + 69t + 365.

Answer:

-5 and -6

Step-by-step explanation:

For trinomial factoring, you need two numbers that add up to get the -11x and two numbers that multiply to get 30.

-5 + (-6) = -11

-5 × -6 = 30

Answer: The anwser is Triangle 2

The given triangle is congruent to the second triangle because they same construction methods and the have same size and same shape.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

We have given a congruent triangle in the picture.

After close observation, the second triangle has the same size and the same shape, and the same construction method by arc method.

Other triangles have different construction methods.

Thus, the given triangle is congruent to the second triangle because they same construction methods and the have same size and same shape.

Answer:

Step-by-step explanation:

Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]

                                           = 360 cm³

2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

   Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

                                                 = [tex]\frac{1}{2}(8)(5)[/tex]

                                                 = 20 cm²

   Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]

                                                             = 80 cm³

5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

    Here, r = radius of the circular base

    h = Height of the cone

    Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]

                                      = [tex]\frac{16\pi }{3}[/tex]

                                      = 16.76 cm³

1 = 61° because it is a corresponding angle to angle 6  

2 = 119° because it is an alternate exterior angle to angle 7  

3 = 61° because it is an alternate angle to angle 1  

4 = 119° because it is an alternate angle to angle 2  

5 = 119° because it is an alternate angle to angle 7  

6 = 61° because is is an alternate angle to 61°  

7 = 119° because it and 61° are supplementary angles (total 180° together)

Answer:

1 = 61° because it is a corresponding angle to angle 6

2 = 119° because it is an alternate exterior angle to angle 7

3 = 61° because it is an alternate angle to angle 1

4 = 119° because it is an alternate angle to angle 2

5 = 119° because it is an alternate angle to angle 7

6 = 61° because is is an alternate angle to 61°

7 = 119° because it and 61° are supplementary angles (total 180° together)

Step-by-step explanation:

Subtract 4 from both sides:

Solve with the quadratic formula:

[tex]x_{1,\:2}=\frac{-8\pm \sqrt{8^2-4\cdot \:4\cdot \:3}}{2\cdot \:4}[/tex]

[tex]x_{1,\:2}=\frac{-8\pm \:4}{2\cdot \:4}[/tex]

Separate the solutions:

Step-by-step explanation:

Answer: 2 (x + y) = 29

2 (x + y - 2) = 25

y = 29/2 - x

Expanded forms:

2 x + 2 y - 4 = 25

2 x + 2 y - 29 = 0

Real solution:

y = 29/2 - x

Solution:

y = 29/2 - x

Solution for the variable y:

y = 1/2 (29 - 2 x)
