From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.
We know that : Area of a square is given by : Side x Side
Given : Side of the square = 3 cm
⇒ Area of the square = 3 x 3 = 9 cm²
We know that : Area of the triangle = 1/2 x Base x Height
From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm
⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²
Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles
⇒ Surface area of the pyramid = 9 cm² + 4(4.5) cm²
⇒ Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²
Answer : Surface area of the pyramid = 27 cm²

acb is 60 equilateral triangle
then dac angle is 120 double of centre angle
triangle dac is isoceles so 2 into angle acd=180-120
then acd =30
Find the measure of A. No links!!!!
Answer:
A equals 105 degrees, option 2
Step-by-step explanation:
7x + 5x gives 180. 7x and 5x lie on a line so they form a linear pair. Their sum equals 180 degrees:-
7x + 5x = 180
12x = 180
x = [tex]\frac{180}{12}[/tex]
x = 15
Since x is 15, we can find the lengths of 7x and 5x.
7x would be 7 x 15 = 105
5x would be 5 x 15 = 75
'A' is equal to 7x since they are vertically opposite angles.
Since 7x is 105 degrees, then A would be 105 degrees as well.

In the diagram shown overline AD and intersect at point E. overline AB and overline CD are parallel . Given the segment length shown in the picture, which of the following is the length overline AE
1) 11.25
2) 10.8
3) 10
4) 7.5
Answer:
11.25
Step-by-step explanation:
Since AB and CD are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B. Therefore the two triangles are similar by the AA postulate. Now, the corresponding sides are in proportion
Since AE ↔ DE and AB ↔ CD
So, AE/CD = AB/CD
AE/5 = 9/4
AE = 9(5)/4
= 45/4 = 11.25
2. The two figures are similar. Complete sentences

Miss Torres is mailing a package that way it's 12.5 pounds the post office charges by the ounce to mail a package how much does the package weight in ounces
Answer: 200 ounces
Step-by-step explanation:
One pound is the equivalent of 16 ounces.
To convert 12.5 pounds to ounces therefore, one needs to multiply 12.5 by 16 ounces:
= 12.5 * 16
= 200 ounces
The package to be mailed weighs 200 ounces when converted from pounds.
Answer:
200 ounces
Step-by-step explanation:
we need to convert 12.5 pounds to ounces
1 pound = 16 ounces
16 x 12.5 = 200 ounces

Which point represents the quotient of 4+3i/-i
Answer: Point C.
Step-by-step explanation:
Point B represents the quotient of 4+3i/-i.
What is a complex number?Complex numbers are the numbers that are expressed in the form of
a + ib where, a, b are real numbers and 'i' is an imaginary number called “iota”.
Given complex number
[tex]\frac{4+3i}{-i}[/tex]
= [tex]\frac{4+3i}{-i} \times \frac{i}{i}[/tex]

Answer:
[tex]\text{a. }x=7, x=-7, \\\text{b. }x=16, x=-16, \\\text{c. }x=3, x=-17, \\\text{d. }x=7, x=-7[/tex]
Step-by-step explanation:
For [tex]|x|=y[/tex], we have two cases:
[tex]\begin{cases}x=y, \\x=-y\end{cases}[/tex]
Using this, we can solve all four of the problems:
[tex]\text{a. }|x|=7,\\\begin{cases}x=7, \\x=-7\end{cases}[/tex]
[tex]\text{b. }|2x|=32,\\\begin{cases}x=16, \\x=-16\end{cases}[/tex]
[tex]\text{c. }|x+7|=10,\\\begin{cases}x+7=10, x=\boxed{3,} \\x+7=-10, x=\boxed{-17}\end{cases}[/tex]
[tex]\text{d. }5|x|=35,\\\begin{cases}x=7, \\x=-7\end{cases}[/tex]
Answer:
a) x = 7, x = - 7
b) x = 16, x = - 16
c) x = 3, x = - 17
d) x = 7, x = - 7
Step-by-step explanation:
When you have absolute value on a variable, the variable has two results.
Example:
lxl = 2
x = 2, or x = - 2
a. lxl = 7
x = 7, x = - 7
b. l2xl = 32
l2xl ÷ 2 = 32 ÷ 2
lxl = 16
x = 16, x = - 16
c. lx + 7l = 10
x + 7 = 10
x + 7 = - 10
x + 7 = 10
x + 7 - 7 = 10 - 7
x = 3
x + 7 = - 10
x + 7 - 7 = - 10 - 7
x = - 17
d. 5lxl = 35
5x = 35
5x = - 35
5x = 35
5x ÷ 5 = 35 ÷ 5
x = 7
5x = - 35
5x ÷ 5 = - 35 ÷ 5
x = - 7
What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
X2 + 23x – 19 = 9x - 4
Answer:
(x + 7)^2 = 64
Step-by-step explanation:
x^2 + 23x – 19 = 9x - 4
x^2 + 23x - 9x = -4 + 19
x^2 + 14x = 15 = 0
Completing the square:
(x + 14/2)^2 - (14/2)^2 = 15
(x + 7)^2 - 49 = 15
(x + 7)^2 = 64

Georgina likes to read during her summer break. The table below shows the number of pages in each book she read last summer and the number of pages in each book she read this summer.

140
220
190
180
190
This Summer
150
170
150
190
180
What inference can someone draw about the data?
The books she read this summer had more pages, on average, than last summer.
The number of pages in each book varied more last summer than this summer.
Last summer, the average book had nearly twice the number of pages than the average book has this summer.
This summer, the number of pages in a book varied nearly twice as much as the number of pages in last summer's books
The correct answer would be:
B. The number of pages in each book varied more last summer than this summer.
Step-by-step explanation:
I was doing my test and this was the correct answer. Sorry if this is too late for you.! I hope you have a great day.
The inference that can be drawn from the data is the number of pages in each book varied more last summer than this summer.
How to measure variance in data?Range can be used to measure variance in a data set. Range is the difference between the largest number and the smallest number. The larger the difference, the greater the variance.
Range= largest number - smallest number
Range of pages read this summer = 180 - 150 = 30
Range of pages read last summer =220 - 140 = 80
