What is the surface area of this? Please help me. Very urgent. Thanks!

Answers

Answer 1

Answer:

[tex]\huge\boxed{\sf 160\ cm\²}[/tex]

Step-by-step explanation:

Area of the Square:

= Length * Length

Where length= 8 cm

= 8 * 8

= 64 cm²

Area of the Triangle:

= 1/2 (Base)(Height)

Where base = 8 cm, height = 6 cm

= 1/2 (8)(6)

= (4)(6)

= 24 cm²

Area of 4 triangles:

= 4(Area of triangle)

= 4(24)

= 96 cm²

Surface Area of Pyramid:

= Area of Square + Area of 4 Triangles:

= 64 + 96

= 160 cm²

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Focus on triangle QAC. We're given that CQ = CA, which in turn means the angles opposite these sides (angles A and Q in that order) are congruent. This is one property of isosceles triangles. Let's make x equal to each of these angles.

With inscribed angle QAC = x, it doubles to 2x which is the measure of minor arc BC (inscribed angle theorem). Minor arc AB is also 2x, since we're told these two arcs have the same measure.

If minor arc BC = 2x, then cutting this in half leads to x again, which points to inscribed angle BDC equal to x. Notice how inscribed angles QAC and BDC subtend the same minor arc BC. Through similar logic, inscribed angle BDA is also x.

In short: angle BDC = angle BDA = x. This leads to angle ADC = 2x. We'll use this later.

-------------------

Let's go back to triangle QAC. The angles A and Q are both x each. The missing angle C is...

Q+A+C = 180

x+x+C = 180

2x+C = 180

C = 180-2x

Making angle QCA equal to 180-2x

Angle ACD is supplementary to this.

So,

angle ACD = 180-(angle QCA) = 180-(180-2x) = 2x. We'll use this later as well.

---------------------

The first section concluded with angle ADC = 2x, while the second section concluded with angle ACD = 2x

For triangle ACD, the bottom angles C and D are both 2x. This is sufficient evidence to show that triangle ACD is isosceles. Furthermore, it means AC = AD, which are the sides opposite angles D and C respectively.

find the direction angle of -12i - 35j

Answers

Answer:

[tex]\theta=71.07^{\circ}[/tex]

Step-by-step explanation:

The given vector is :

v = -12i - 35j

We need to find the angle direction of v.

The general vector is given by :

v = xi+yj

The direction angle is :

[tex]\theta=\tan^{-1}(\dfrac{y}{x})[/tex]

We have, x = -12 and y = -35

So,

[tex]\theta=\tan^{-1}(\dfrac{-35}{-12})\\\\\theta=71.07^{\circ}[/tex]

So, the required direction angle is [tex]71.07^{\circ}[/tex].

James scored the following points per game in the last five basketball
games he played: 31, 20, 27, 19, 28. Find the mean absolute deviation of the
number of points scored. *
A. 4.4
B. 6.2
C. 25
D. 125

Answers

The answer is C, you add them all up and divide by 5

The mean absolute deviation of the number of points scored is 4.4.

What is Mean Deviation?

The mean deviation is used to calculate how far the values fall from the mean of the data set.

Here, Given data is 31, 20, 27, 19, 28

Mean = Sum of all data / number of terms

= (31 + 20 + 27 + 19 + 28)/5

= 125/5

= 25

Then, the deviation will be 6, 5, 2, 6, 3

Mean Deviation = Sum of Deviation / Total number of deviation

= ( 6 + 5 + 2 + 6 + 3) / 5

= 22 / 5

= 4.4

Thus, the mean absolute deviation of the number of points scored is 4.4.

According to the graph, what is the value of the constant in the equation
below?

Answers

Answer:

The value of the constant in the equation below is 20.

Step-by-step explanation:

You are given the formula height = constant/width. All you have to do is take one of the points given on the graph and plug it in to the formula.

Example:

1 = Constant/20

Constant = 20

As per linear equation, the Constant in the given graph is 20.

What is a linear equation?

A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.

Here, Height = Constant/Width

Therefore, Constant = Height × Width

We can take any two random points given on the graph.

Two points are (5, 4) and (20, 1).

For the first point,

Height = 4, Width = 5.

Therefore, Constant = 4 × 5 = 20

For the second point,

Height = 1, Width = 20.

Therefore, Constant = 1 × 20 = 20

Therefore, Constant in the given graph is 20.

Answers

Answer:

y is 107° and z is 36°

Step-by-step explanation:

73° and y are supplementary angles so they add up to 180°

Answer:

y = 107

z = 36

Step-by-step explanation:

We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:

y + 73 = 180

and

y = 107

Next, using vertical angles, we can say that:

5z - 73 = y

We already have y = 107, so we can substitute that in:

5z - 73 = 107

5z = 180

z = 36
