A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2.
Answer:
16√3 cm³
Step-by-step explanation:
The volume of a triangular prism is given as:
V = (1/3)B*h
Where B is the area of the base and h is the height of the prism.
Given that B = 12√3. The height fro the diagram is BC.
Since ∠BAC = 30° and ∠BCA = 90°, we can find BC using trigonometric identity.
tan(30) = BC / AC
but AC = 4√3, hence:
tan(30) = BC / (4√3)
BC = 4√3(tan 30)
BC = 4
V = (1/3)B*h = (1/3)B* BC = (1/3) * 12√3 * 4 = 16√3 cm³
Answer:
its b

A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.
What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.
Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,
Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³
Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

You buy a shirt on sale for $20. This
sale price is 20% off the original price.
How much was the original price of
the shirt?
Answer:
$25
Step-by-step explanation:
Let the original cost of the shirt be x, therefore the sale price would be the original minus the 20% of the original price x - 0.20x = $20. Solve for x: 0.8x = 20 --> x=$25

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
Answer:
(10/3, 1)
Step-by-step explanation:
Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;
X = ax1+bx2/a+b
Y = ay1+by2/a+b
Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1
X = 2(4)+1(2)/2+1
X = 8+2/3
X = 10/3
Similarly;
Y = 2(4)+1(-5)/2+1
Y = 8-5/3
Y = 3/3
Y = 1
Hence the required coordinate is (10/3, 1)

What is the total surface area?? PLEASE HELP THIS IS A QUIZ IM SO CONFUSED
Answer:
246 cm
Step-by-step explanation:
So I solved for the two triangles, 6x8=48/2=24, since there are 2, I multiplied by 2 to get 48 (Could've kept it just as 48 but it's good to keep the habit of dividing by 2 to get area of a triangle). Then I did 6x9 for the front rectangle to get 54, and then solved for the right and back rectangle by doing 9x8 to get 72, 72x2=144
144+48+54= 246

Write the equation in standard form of a line that is parallel to the graph of 2x + y = 5 and whose y - intercept is (0,4).
The line that is parallel to this line will have the same slope of this line, as the two will never intersect. They will run side by side. The line y = 2x - 5 is written in slope-intercept form, which is y = mx + b. The value of m represents the slope, and in this equation m = 2. Therefore, the line we are looking for will have a slope of 2 also.
That line should also be in slope-intercept form. We now know the value of m, but we also know the value of x and y. The ordered pair (8, 10) is a point on the line, and every ordered pair is in the form (x, y). Therefore, x = 8 and y = 10. We can plug those values into y = mx + b, along with m = 2. That gives us:
10 = 2(8) + b We need to solve for b.
10 = 16 + b
b = -6
