Answer:
Area: 272ft²
Volume = 82.6236447189ft³
Step-by-step explanation:
AREA
The area of a square pyramid is found by combining the area of the base and the area of the triangular faces:
Area of base = area of square = L² = 8² = 16ft²
Area of one triangular face = (1/2)bh = (1/2)(8)(16) = 64ft²
There are four triangular faces so the total area = 16+4(64)= 16+256= 272 ft²
VOLUME
The volume of a square pyramid = (a²)(h/3), where a is the length of the base and h is the length from the top of the pyramid to the middle of the square.
We are given a, but not h. To find h, we must imagine a right-angled triangle within the pyramid, where 16ft is the hypotenuse, h is the height and the base is half of a (since the base is a square and the distance is from the edge to the middle). We can then use pythagorus's theorem to find h:
A²=B²+C²
16²=(8/2)²+h²
256=16+h²
h=√240
h=15.4919333848ft
Knowing h, we can find the volume:
Volume = (a²)(h/3)
Volume = (8²)(15.4919333848/3)
Volume = (16)(5.16397779493)
Volume = 82.6236447189ft³

(6,1) is the correct answer
Answer: (-2,5)
Step-by-step explanation:
All of the dimensions of the solid are multiplied by a factor of k=10 how many times greater is the surface area of the new solid? How many times greater is the volume of the new solid?
URGENT PLS PLS PLSPLSOWSOQDNPN
Step-by-step explanation:
The surface area increases by 100
if x y and z are side lengths and it is a rectangle.
Then finding the surface area would normally be 2xy+2yz+2xz
But then increasing each side length by a factor of 10 means multiplying it together
2x(10)y(10)+2y(10)z(10)+2x(10)z(10)
200xy+200yz+200xz and that is 100 times greater than the normal surface area.
Volume:
(x)(y)(z)=normal volume
x(10)y(10)z(10)=increased value
1000xyz=new volume
that is 1000 times greater than the previous volume
Hope that helps :)
What is the remainder of (x4 - 2x2 + x - 3) ÷ (x - 1)
Step-by-step explanation:
First simplify the parentheses. [tex]4x-2x^2+x-3=-2x^2+5x-3[/tex], and [tex]x-1[/tex] can't be simplified, so the equation has now been simplified to [tex]\frac{-2x^2+5x-3}{x-1}[/tex]. The equation can be divided to equal [tex]-2x+3[/tex], so I'm guessing either there is no remainder or the 3 is the remainder.
Hope this helps!

Answer:
3 lessons
Step-by-step explanation:
available hours: 4 hrs 30 min
time per lesson: 1 hr 30 min
2 lessons is 3 hrs
which leaves even time for one more lesson after 2 lessons
So, she can schedule 3 lessons in 4 hrs in 30 min
Where do I put the parentheses in 21-8-6=7
Answer:
around 21-8 so the equation would look like this (21-8)-6=7
Step-by-step explanation:
you do this because if u put the parentheses around 8-6 you would get 21- (8-6)= 19 because 21 - 2 = 19 so you have to put them around 21-8 to get the right answer

Find the area of the following figure: 2ft 6ft 6ft 12ft
Answer:
96 ft²
Step-by-step explanation:
Area of triangle + area of square
Area of triangle = (base × height)/2
= 120/2=60
Area of square = 6 × 6=36
60 + 36= 96

Answer:
Perimeter of base = 18 ft
Height = 7 ft
Base area = 12ft²
SA= 150 ft² *
Step-by-step explanation:
Perimeter of base = 8+5+5=18 ft
Height = 7 ft
Base area = 1/2x8x3=12ft²
SA= (8x7)+(12+12)+2(5x7)=56+24+70=150 ft²
*There are several different way to figure out the surface area, so I’m not sure exactly how they want it displayed. 150 is the answer though. Plus, I think there was supposed to be an addition sign between the first two parentheses.

That’s just your millennial snowflake brain being unable to comprehend real work. My grandpa lost both his thumbs to frostbite while walking 29.67 kilomiles to school in 10 feet of snow in the summer uphill both ways and he could still wield any tool known to man. And he did so for 83 and a half years until they forced him to retire because he was making all the other workers look like pansies. When he was told he was being forced to retire, he marched into the CEO’s office and declared “I’d rather be dead than a deadbeat.” Then he dropped dead on the spot. Now that’s loyalty!

[tex] \large \boxed{y = - \frac{2}{3} x + 2}[/tex]
Step-by-step explanation:
both slopes multiply each others must equal to -1 for perpendicular.
[tex] \large{m_1m_2 = - 1}[/tex]
Let m1 = 3/2
[tex] \large{ \frac{3}{2} m_2 = - 1} \\ \large{3m_2 = - 2} \\ \large{m_2 = - \frac{2}{3} }[/tex]
Therefore -2/3 is perpendicular to 3/2. Because the line passes through (6,-2)
[tex] \large{y - y_1 = m(x - x_1)}[/tex]
Given (x1, y1) = ordered pair
Therefore (x1, y1) = (6,-2)
and m = - 2/3
[tex] \large{y + 2 = - \frac{2}{3} (x - 6)}[/tex]
Write in slope-intercept form.
[tex] \large{y = - \frac{2}{3} x + 4 - 2} \\ \large{y = - \frac{2}{3}x + 2}[/tex]

What is the volume of a rectangular crystal with a length (1) of 2.2 cm, a width (w) of 2 cm, and a height
(h) of 1.8 cm?
Answer:
7.92 cm^3
Step-by-step explanation:
To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.
