So we want to find the surface area of this pyramid. Finding the surface area of a 3D shape is essentially finding the area of all its sides and adding them together.
What we're going to have to do here is find the area of the base of the pyramid, which is basically a square, and find the area of all four sides of the pyramid, which are triangles.
Formula for area of a square: length × width
Formula for area of a triangle: (base × height) ÷ 2
First we will find the area of the base:
l × w = A
(Write out formula)
8 × 8 =
(Input values)
A = 64 m^2 (square meters or meters squared)
(We have our answer, dont forgot to write your units.)
So we've figured out the area of the base. Now onto the triangles:
(b×h) ÷ 2 = A
(Write out formula)
(8 × 6) ÷ 2 =
(Input values)
48 ÷ 2 =
(Use PEMDAS to solve this correctly. We did whatever was in the parenthesis first, which was multiplication.)
A = 24m^2 (square meters or meters squared)
(We have our answer.)
Now we've found the area of the base of the pyramid and one of the sides of the pyramid, but we're almost done! There's four sides to the pyramid, they're all the same. So since we found the area for one, we can multiply that by 4 to find the area of all sides added together:
24 × 4
(area of a side × total sides)
= 96m^2
All that's left is adding the 96 to the area of the base to get our total surface area of the pyramid:
96 + 64 = 160
The surface area of the pyramid is 160m^2(square meters or meters squared)
(Hope this helps :) )

Find the percent of change from 6,570 pt to 16,425 pt.
Answer:
Percentage Change | Increase and Decrease
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
Step-by-step explanation:
hopefully this helped and you can find the percent change.

Enter your answer by filling in the boxes.
y = x +
pls say why and explin it so i can understand it }btw its 8th grade
Answer:
y=5x+3
Step-by-step explanation:
You have the points (1,8) (2,13) (3,18) (4,23)
first you want to find the slope. The equation to find a slope is y2-y1 / x2-x1
your points (1,8) and (2,13) are really all you need
1 would be your x1 and your 2 would be your x2.
8 would be your y1 and 2 your y2
so you want to plug those into your equation y2-y1/x2-x1
13-8 /2-1 you get 5/1
Simplify your answer is 5 for your slope
Now finding the y intercept or "b" I normally just find the pattern of the sequence so in this case when you add one to the top your adding five to the bottom like
x 1 2 3 4
y 8 13 18 23
so to get to your y intercept which is (0,y)
subtract 1 from the top to get zero and subtract 5 from the bottom to get 3 so your y intercept is 3.
Hope this helps.

Formula for finding the surface area of a rectangular prism:
2(wl + hl + hw)
First, let's find out which one of the measurements is the height, length, or width.
6m = length
16m = width
3m = height
Next, we calculate the surface area. We have to do the formula one by one too.
2(wl + hl + hw)
2(16x6 + 3x6 + 3x16)
16 x 6 = 96
3 x 6 = 18
3 x 16 = 48
Now, we add those together.
96 + 18 + 48 = 162
Lastly, multiply by 2.
162 x 2 = 324
Therefore, A = 324m²

Which point is close to the origin and by how much?
Question:
Point ( a or b ) Is closer by ( less than or more than ) 0.1 units
The first select on the question Is A or b and the second was If its more than or less than
Answer:
B is closer.
Step-by-step explanation:
If you go down 6, and over 2, it's a total of 8 units to get to the origin. For A, if you go down 5 units, and go right 4 units, it's 9 units to get to the origin. When you do the Pythagorean Theorem for A, you get 41, and square rooting that gives you 6.4. When you do the Pythagorean Theorem for B, you get 40, and square rooting it gets you 6.3. Therefore, B is closer. I don't really get the more than / less than .1 unit but if I had to guess, it'd be less than 0.1 unit because 6.3 is lesser than 6.4 by .1.
Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0.-4).
Oy=-x?
Oy2 = -4x
Oy2 = -16%
Oyə tox?
Answer:
\(x^2 = -16y\)
Step-by-step explanation:
Given
\(Vertex = (0,0)\\Focus = (0,-4)\)
Required
Equation of the parabola (in standard form)
The standard form of a parabola is \((x - h)^2 = 4p (y - k),\)
Such that
Vertex = (h,k)
Focus = (h, k + p)
For the vertex
This implies that (h,k) = (0,0)
h = 0 and k = 0
For the focus
This implies that (h, k + p) = (0, -4)
\(h = 0\\k + p = -4\)
Recall that \(k = 0;\)
Hence, \(0 + p = -4\)
\(p = -4\)
Substitute \(p = -4\), \(h = 0\ and\ k = 0\) in the given formula
\((x - h)^2 = 4p (y - k),\) becomes
\((x - 0)^2 = 4 * -4 (y - 0),\)
\((x)^2 = 4 * -4 (y),\)
\(x^2 = -16 (y),\)
\(x^2 = -16y\)
Hence,, the standard form is \(x^2 = -16y\)

Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

Answer:
An eclipse happens when a celestial object moves into the shadow made by another celestial object. In the case of a solar eclipse, the Moon moves into the shadow of the Earth, and in the case of a lunar eclipse, Earth moves into the shadow of the Moon.
The most likely reason for the Sun always shining in the summer in Barrow, Alaska is that Earth's axis is tilted, so sometimes parts of Earth face the Sun for the entire daily rotation.
When Earth is in Position C in the diagram, it is spring in the Northern Hemisphere because the Northern Hemisphere is tilting toward the Sun and receiving more direct sunlight than Position B.
The city that will most likely experience the mildest winters is Tallahassee, Florida because it is closest to the equator and receives the most direct sunlight.
When Earth, the Sun, and the Moon line up in a straight line, a lunar or solar eclipse can happen.
The point that indicates the location of the Moon that is the best for viewing a lunar eclipse from Earth is P.
A solar eclipse can only happen during a new moon because, during a new moon, the Moon is between the Sun and Earth. This allows the Moon to block the sunlight and create an eclipse.
Answer:
During a total lunar eclipse, Earth blocks sunlight from reaching the Moon. Earth casts a shadow onto the Moon. The Moon can look reddish orange.An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. Let’s learn about the two types of eclipses on Earth.What Is a Lunar Eclipse?The Moon moves in an orbit around Earth. At the same time, Earth orbits the Sun. Sometimes Earth moves between the Sun and the Moon. When this happens, Earth blocks the sunlight that normally is reflected by the Moon. (This sunlight is what causes the Moon to shine.) Instead of light hitting the Moon's surface, Earth's shadow falls on the Moon. This is an eclipse of the Moon, or a lunar eclipse. A lunar eclipse can occur only when the Moon is full.A lunar eclipse can be seen from Earth at night. There are two types of lunar eclipses: Although the Moon is in Earth's shadow, some sunlight reaches the Moon. The sunlight passes through Earth's atmosphere, which filters out most of the blue light. This makes the Moon appear red to people on Earth.Earth's shadow passes in front of the Moon until it turns red or orange.A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth. What people see from Earth during a partial lunar eclipse depends on how the Sun, Earth and Moon align.A lunar eclipse usually lasts for a few hours. At least two partial lunar eclipses happen every year, but total lunar eclipses are rare. It is safe to look at a lunar eclipse.
