What is the volume of the prism?
Answers
Answer:
Step-by-step explanation:
The volume of a prism is the product of the area of the base and the height of the prism. Prism volume (V) = B × h, where, B is the area of the base and h is the height of the prism. = l × w × h, where l, w, and h are the length, width, and height of the rectangular prism.
The volume of the triangular prism with dimension 2.5 cm, 3.2 cm and 8 cm is 32 cm³.
Given is a triangular prism with dimension 2.5 cm, 3.2 cm and 8 cm.
We need to find its volume.
The volume of the triangular prism = base area × height
Here,
Base area = area of the triangle
= 1/2 × base × height
= 1/2 × 3.2 × 2.5
= 4 cm²
And,
Height of the prism = 8 cm
Substituting the values,
V = 4 × 8
V = 32 cm³
Hence the volume of the prims is 32 cm³.

Answer the following linear equations: x3+y3+z3=k
2x – y = 6, x – y = 2
and ax + by = a-b, bx – ay = a+b
TYVM!! :)
Answers
Answer:
Linear Equation 1 — 3xyz
Linear Equation 2 — x = 4 and y = 2
Linear Equation 3 — x = 1 and y = (-1)
Step-by-step explanation:
(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.
The required result must be 3xyz.
(Linear Equation 2)
2x − y = 6 ....(1)
x − y = 2 ....(2)
Equation(2)−Equation(1) we get
x − y − 2x + by = 2 − 6
(−x) = (−4)
x = 4
Substitute x = 4 in (1) we get
2x − y = 6
2*4 − y = 6
8 − y = 6
(−y) = 6 − 8
y=2
(Linear Equation 3)
ax + by = a − b .......... (1)
bx − ay = a + b .......... (2)
Multiply equation (1) with a and equation (2) with b ,
a²x + aby = a² − ab ..........(3)
b²x − aby = ab + b² ......... (4)
Adding (3) and (4), we get,
(a² + b²)x = a² + b²
x = 1
Now, from (1),
ax + by = a − b
a + by = a − b
by = (−b)
y = (−1)

∠CAB +∠ CBA +∠ ACB = 180°
Sum of all angle of triangle is 180° ..
75 + 75 + ∠ACB = 180°
∠ACB = 180° - 150°
∠ACB = 30°
Now ,
x = ∠ACB ( being vertically opposite angle)
x = 30°
The angle measure of x is 30°.
What is a Triangle?The polygon known as a triangle has three sides and three vertices.
The triangle's total angle is 180 degrees.
Given that a triangle has 2 known angles measuring 75° and 75°.
Let the third missing angle measure is y.
And y and x are opposite angles in the diagram.
So, x = y.
The sum of all the interior angle measures of a triangle is 180°.
So, 75 + 75 + y = 180
y = 180 - 150
y = 30°
So x = y = 30°
Therefore, x = 30°.

If the Percent of Discount is 15% and the Sale Price is $146.54 what the Original Price? PLS Y'ALL GET 100 POINTS FOR DIS! PLS HELP ME!!??
Answers
Answer: the original price of the item was $172.40.
Step-by-step explanation: If the percent of discount is 15% and the sale price is $146.54, we can use the following formula to find the original price:
Original price = Sale price / (1 - Percent discount as a decimal)
First, we need to convert the percent discount to a decimal by dividing it by 100:
15% = 0.15
Substituting the given values into the formula, we get:
Original price = 146.54 / (1 - 0.15)
Original price = 146.54 / 0.85
Original price = $172.40
Therefore, the original price of the item was $172.40.
Answer:
172.40
Step-by-step explanation:
w-[0.15]=146.54
so w-85p=146.54
146.54 divided by 80=1.724 so when you make it a percent it turns it into 172.40 which is the final answer for the money.

A. 1 to 12
Step-by-step explanation:
if each business has 4 executives there is a total of 120 executives
30(4) = 120
to find the proportion of executives to offices we divide the number of offices by the number of executives
1440/120 = 12
a more in depth look is
1440 offices / 120 executives
"offices" and "executives" cannot divide each other out, but the 1440 and 120 can so it would be

Surface area of triangular pyramid:In the triangular pyramid, base is an equilateral triangle, and the lateral faces are congruent triangles. So, to find the surface area add the area of base triangle with the area of 3 lateral triangles.
a) Base area of pyramid:
b= 8 cm
h = 6.9 cm
[tex]\boxed{\bf base \ area \ of \ pyramid = \dfrac{1}{2}*b*h}[/tex]
[tex]= \dfrac{1}{2}*8*6.9\\\\=4*6.9\\\\= 27.6 \ ft^2[/tex]
b) Area of one lateral surface area of pyramid:
b = 8 cm
slant height = l = 9 cm
[tex]\boxed{\text{\bf area of one lateral surface area of the pyramid = }\dfrac{1}{2}b*l}[/tex]
[tex]\sf = \dfrac{1}{2}*8*9\\\\= 4 * 9\\\\= 36 \ ft^2[/tex]
c) Lateral surface area of the pyramid = 3 * area of one lateral surface area of pyramid
= 3 * 36
= 108 ft²
d)TSA of pyramid:
[tex]\boxed{\text{\bf Total surface area of pyramid = base area + lateral surface area}}[/tex]

Answer: 0.12, 1/8, 14%, 0.2
Step-by-step explanation:
We can try and convert everything to a decimal in order to make things easier. 0.12 and 0.2 are already given to us. Now we convert 1/8 to a decimal by dividing 1 by 8 and you should get 0.125. Next convert 14% to a decimal by moving the decimal place 2 places foward, which gives you 0.14. Your numbers are 0.12, 0.2, 0.125, and 0.14 now you place them into order from least to greatest. Since one of them is three digits you can make the rest three digits to make it easier. 0.120, 0.200, 0.125, 0.140.
Your final answer would be 0.12, 0.125, 0.14, 0.2

1/3 + 1/3 + 1/3 + 1/3 + 1/3 =

5/3 or 1 2/3
Answer: (a) 1 1/2 and (b) 1 2/3
Step-by-step explanation: (a) 1/2 + 1/2 + 1/2 = 1/2 x 3
= 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).
Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)
(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
= 5/3
mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)
