What is the lateral surface area of the square pyramid represented by this net?
Answers
Answer:
340 ft²
Step-by-step explanation:
From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width equals its length).
First, find the area of the square.
Area of a square = width x length = 10 x 10 = 100 ft²
All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.
Area of a triangle = 1/2 x base x height = 1/2 x 10 x 12 = 60 ft²
So the total area of all 4 triangles = 4 x 60 = 240 ft²
Therefore the total surface area = 100 + 240 = 340 ft²
Answer:
340 ft²
Step-by-step explanation:
The surface area of a shape is basically the area of its faces.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
1. First, Let's find the area of the triangles. To find the area of a triangle, we need to multiply the height and the base and then divide the product by 2.
[tex]\rightarrow \text{Area of triangle} = \dfrac{12 \times 10}{2}[/tex]
Now, let's find the area of the triangle by simplifying the RHS.
[tex]\rightarrow \text{Area of triangle} = 6 \times 10[/tex]
[tex]\rightarrow \text{Area of triangle} = 60 \ \text{ft}^{2}[/tex]
Since there are four triangles, we need to further multiply the area of the triangle by 4 to find the area of four triangles.
[tex]\rightarrow \text{Area of four triangles} = 4(60)[/tex]
[tex]\rightarrow \text{Area of four triangles} = 240 \ \text{ft}^{2}[/tex]
2. Now, let's find the area of the square. To find the area of the square, we need to square the side length.
[tex]\rightarrow \text{Side length} = 10 \ \text{ft}[/tex]
[tex]\rightarrow \text{Area of square} = 10^{2}[/tex]
[tex]\rightarrow \text{Area of square} = 100 \ \text{ft}^{2}[/tex]
3. Lastly, let's find the surface area. To find the surface area of the figure, we need to sum up the area of the triangles and the area of the square.
[tex]\rightarrow \text{Surface area of pyramid: 4(Area of triangle) + Area of square}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 240 + 100}[/tex]
[tex]\rightarrow \text{Surface area of pyramid: 340 \text{ft}}^{2} }[/tex]

O x < -2 .
OX > -2
Answers
Answer:
x > - 2
Step-by-step explanation:
- 9x - 15 < 3 ( add 15 to both sides )
- 9x < 18
Divide both sides by - 9, reversing the symbol as a result of dividing by a negative quantity.
x > - 2
The solution to the inequality - 9x - 15 < 3 is, x > - 2.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality of the form - 9x - 15 < 3.
- 9x < 3 + 15.
- 9x < 18.
Now, Moving the variable to the other side to make it positive we have,
9x > - 18.
x > - 18/9.
x > - 2.

What is law of sines?For any triangle ABC, with side lengths |AB| = c units, |BC| = a units, and |AC| = b units, then
[tex]\dfrac{sinA}{a} = \dfrac{sinB}{b} = \dfrac{sinC}{c}[/tex]
(If you draw it, you will notice that sin of an angle is sitting over the side length of its opposite side. This is the most important thing that people can mistake most commonly).
Using the above fact to calculate the measure of 'a' for the given contextWe have these data
sin A = sin(40 degrees) = 0.643 approx
sin(b) = sin(95) degrees) = 0.996 approx
b = 4.7 cm
Using the first two inequalities, we get
[tex]\dfrac{sinA}{a} = \dfrac{sinB}{b} \\\\\dfrac{0.643}{a} = \dfrac{0.996}{4.7}\\\\a = \dfrac{0.643}{0.212} \approx 3 \: \rm cm[/tex]

The average of two numbers is 55. Ir their positive difference is 64, then determine the two numbers algebraically.
Answers
Answer:23,87
Step-by-step explanation:
call the 2 numbers x and y
average of 2 numbers being 55 means (x+y)/2 = 55
if the positive difference of the two numbers is 64 then x-y=64
since you have two equations and two variables you can solve for x and y
(x+y)/2 = 55 --> x+y=110
x-y=64 --> x=64+y
x+y=110 and x=64+y --> 64+y+y=110
y=23
x=87
the two numbers are 23 and 87
Answer:
87,23
Step-by-step explanation:
Let larger number be x other smaller number be y,
Given,
(x+y)/2=55
or, x+y=110---(i)
x-y=64---(ii)
Adding eqn (i) & (ii), we get,
x+y=110
+x-y=64
2x=174
x=87
Again,
Putting x=87 in eqn (ii), we get,
87-y=64
87-64=y
y=23
Each of 5 boys randomly chooses a watch from 12 different styles. What is the probability that at least 2 boys choose the same type of watch?
Answer with explanation gets brainliest.
Answers
Answer:
Ok. So we have 12 different styles of watches to choose from, so that means that the total number of combinations of styles for 5 boys is 12*12*12*12*12, since each boy has his pick of 12 options.
The way to answer this question is by way of the complementary rule: We want the number of ways that the boys can all have different styles. So the first boy to pick has 12 options available to him, the second boy has 11 options available to him, the 3rd boy has 10 options available to him, so on and so forth.
So the probability that the boys all have different watches is (12*11*10*9*8)/12^5= .3819.
To find the probability that at least two boys have the same style would just be 1 -.3819 = 6181
