What is the volume of the regular pyramid below?
OA. 108 units3
OB. 648 units3
Oc. 144 units3
OD. 216 units
Answer:
D. 216
Step-by-step explanation:
What I did was I multiply 9x9x8 and got 648. I then divide 648 by 3 and got 216. I would appreciate it if you can mark this the brainliest if you can.
The volume of the regular pyramid is V = 216 units³
What is the volume of a pyramid?The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.
Volume of Pyramid = ( 1/3 )a²H
Given data ,
Let the volume of the pyramid be represented as V
Now , the equation will be
Let the height of the pyramid be H = 8 units
Let the side length of the pyramid a = 9 units
Now , Volume of Pyramid = ( 1/3 )a²H
On simplifying , we get
The volume of pyramid V = ( 1/3 ) ( 9 )² ( 8 )
The volume of pyramid V = ( 27 ) ( 8 )
The volume of pyramid V = 216 units³
Hence , the volume of the pyramid is 216 units³

please answer fast!!! drag each figure to show if it is similar to the figure shown or why it is not similar
Answer:
The similar figures are shown in the attached drawing created with Microsoft Visio;
The similar figures are the rectangles in figures 2, and 5
Step-by-step explanation:
The given figure is a rectangle with dimensions of 3 yd. by 9 yd., therefore the length = 3 × The width of the rectangle
1) The 9 yd. by 18 yd. figure is a rectangle with the length = 2 × The width of the rectangle, therefore, the figure is not similar to the given rectangle
2) The 3 yd. by 1 yd. figure is a rectangle with the width = 3 × The length of the rectangle, therefore, the figure is similar to the given rectangle
3) The figure is a trapezium, while the given figure is a rectangle, therefore, they are not similar
4) The 6 yd. by 3 yd. figure is a rectangle with the width = 2 × The length of the rectangle, therefore, the figure is not similar to the given rectangle
5) The 6 yd. by 18 yd. figure is a rectangle with the length = 3 × The width of the rectangle, therefore, the figure is similar to the given rectangle
6) The 2 yd. by 8 yd. figure is a rectangle with the length = 4 × The width of the rectangle, therefore, the figure is not similar to the given rectangle
Fill in the missing amounts in the balance sheet after the following transactions.
You start with $3,500 in cash and in owner's equity.
a. You sell product purchased for $750 for $1,525.00
b. You purchase equipment for $500.
c. You pay the rent by check for $450.
d. You receive next month's power bill for $155.00
Assets Liabilities and Owner's Equity
Cash $
Accounts Payable $
Equipment $ 500.00 Owner's Equity: Investment $
Total Assets $
Total Liabilities and Owner's Equity $
Answer:
Cash- $3,325.00
Total Assets- $3,825.00
Accounts payable- $155.00
Owners Equity- $3,670.00
Total- $3,825.00
The accounting equation as per accounting principle is that Assets balance on any date is equal to balance of liabilities and owner's equity. So the cash balance on period end date is $3325.00
What is an accounting equation?The entire assets of a corporation are equal to the sum of its liabilities and shareholders' equity, according to the accounting equation. The basic idea behind the double-entry accounting system is that assets, liabilities, and equity have a clear relationship with one another.
a) So the balance of cash = $3,500 - $750 + $1,525.00 - $500 - $450 - = $3325.
b) Balance of Accounts Payable = $155.00 = Outstanding power bill.
c) Equipment $ 500.00.
d) Investment = $0.00
E) Total Assets = $ 3825 = cash + Equipment +
F) Total Liabilities = $3825 = Owner's Equity + Accounts Payable
G) Owner's Equity = $3,670.00 = $3,500 + $775 - $155 - $450
Therefore the amount of cash and owners' equity of balance sheet can be solved by the use of accounting equation.

2x+1/2y=7
6x-1/2y=5
Answer:
1) Subtracting one from the other
2) x = 0.375 and y = 0.125
Step-by-step explanation:
Equation 1 :
[tex]\frac{2x+1}{2y}=7\\\\[/tex]
Equation 2:
[tex]\frac{6x-1}{2y}=5[/tex]
To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y[/tex]
Now for the second equation:
[tex]\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y[/tex]
Now subtracting equation 2 from equation 1
[tex]12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y[/tex]
now insert this value of y into any equation
lets insert it into equation 1
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375[/tex]

Answer:
B. Intersecting
Step-by-step explanation:
If you were to extend the lines, they would cross eachother
The given lines are intersecting.
What are intersecting lines?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
As, from the figure we can see that the line p and q are not parallel to each other because the distance between them is not constant.
Now, the lines are not either skew or perpendicular.
If we extend the lines p and q then will meet at some point which is know as intersecting lines.

Which expression is equivalent to the sum of the two areas?
Answer:

Olivia's family drove to Disneyland for spring break. Her mom and dad shared driving duties for a total of 14 hours. Her mom drove 65 miles per hour and her dad drove 60 miles per hour. They drove a total of 895 miles. How many hours did each person drive.
Answer: Dad = 3 hours
Mom = 11 hours
Step-by-step explanation:
Let the number of hours driven by her mum be m.
Let the number of hours driven by her dad be d.
We can form equation from the question as:
d + m = 14 ........... i
60d + 65m = 895.......... ii
Since d + m = 14, d = 14 - m
Substitute 14 - m into d in equation ii
60d + 65m = 895
60(14 - m) + 65m = 895
840 - 60m + 65m = 895
840 + 5m = 895
5m = 895 - 840
5m = 55
m = 11
The mother drove for 11 hours
Since d + m = 14
d + 11 = 14
d = 14 - 11
d = 3
The father drive for 3 hours

Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16
= 1.
