The Volume of the triangular prism is 124.74 cubic mm.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill. Volume is a three-dimensional quantity used to calculate the capacity of a container.
Given:
Base of the triangle (b) = 12.3 mm
Height of the triangle (h) = 8.2 mm
Length of the prism (l) = 20.5 mm
So, the volume of the triangular prism formula:
= 1/2 x b x h x l
= 1/2 x 14.4 x 2.1 x 8.25
= 7.2 x 2.1 x8.25
= 124.74 cubic mm.

1st side = x
2nd side = y
3rd side = z
Given: 1st side is 5 less than 2nd side.
x = y - 5
Given: 3rd side is 2 less that 1st side. But we want everything in only one variable to solve. So use the first given 1st side = y - 5
z = y - 5 - 2
z = y - 7
Sum of sides
(y - 5) + y + ( y - 7) = 42
3y - 12 = 42
3y = 42 + 12
3y = 54
y = 54/3
y = 18
Remember the sides, We have
1st, x = y - 5
= 18 - 5
= 13
2nd, y = y
= 18
3rd, z = y - 7
= 18 - 7
= 11

A rectangle has perimeter 68 meters, and its area is 280 sq-meters. find the dimensions of this rectangle. (for purposes of this problem only, the width is shorter than the length.)
Answers
Perimeter is 68 meters
2(x + y) = 68
x + y = 34
x = 34 - y ------------------ (1)
Area = 280
xy = 280 ------------------- (2)
Sub (1) into (2):
(34 - y)y = 280
34y - y² = 280
y² - 34y + 280 = 0
(x - 14)(x - 20) = 0
x = 14 or x = 20
The dimension of this rectangle is 14 meters by 20 meters
Final answer:
The rectangle's length to be 20 meters and the width to be 14 meters.
Explanation:
We are given that a rectangle has a perimeter of 68 meters and an area of 280 square meters, and we need to find its dimensions. Let's call the length of the rectangle L and the width W.
The perimeter (P) of a rectangle is given by the formula P = 2L + 2W. We know the perimeter is 68 meters, so we can write the equation:
1. 68 = 2L + 2W
The area (A) of a rectangle is given by the formula A = L × W. We know the area is 280 square meters, so we can write the equation:
2. 280 = L × W
To find L and W, we solve these two equations simultaneously.
Divide the perimeter equation by 2 to simplify:
34 = L + W
We can then express W in terms of L using this equation:
W = 34 - L
Substitute this into the area equation:
280 = L × (34 - L)
This gives us a quadratic equation:
L2 - 34L + 280 = 0
Solving this quadratic equation, we find that L = 20 and W = 14 or L = 14 and W = 20. Since the width is shorter than the length, the dimensions of the rectangle are length 20 meters and width 14 meters.
A rectangular piece of plastic has an area of 10 square millimeters and a perimeter of 22 millimeters. What are the dimensions of the piece of plastic? millimeters by millimeters
Answers
The dimensions of the rectangular piece of plastic are either 2mm by 5mm or 5mm by 2mm, based on the given area and perimeter.
Explanation:We'll use the formula for the perimeter of a rectangle: 2(length + width) = perimeter and the formula for area: length x width = area. Given we have area of 10mm2 and perimeter of 22mm, we can set up two equations. Let's denote the length as 'L' and the width as 'W'.
Formula of perimeter of a rectangle: 2(L + W) = 22
Formula of area of a rectangle: L * W = 10.
We solve these two equations simultaneously. We get two possible solutions: Dimensions could be either {2mm, 5mm} or {5mm, 2mm}. Either the length is 5mm and the width is 2mm, or the length is 2mm and the width is 5mm.

A perpendicular bisector, CD , is drawn through point C on AB.
If the coordinates of point A are (-3, 2) and the coordinates of point B are (7, 6), the x-intercept of CD is ____ . Point ___ lies on CD.
Part 1 options
(3,0)
(18/5,0)
(9,0)
(45/2,0)
Part 2 options
(-52,141)
(-20,57)
(32,-71)
(54,-128)
Answers
First let us find the equation of AB. It should be in the form of y=mx + b
From the given coordinates, you can get m, x, and b.
m= y2-y1 divided by x2 - x1
m=(6-2)/(7- -3)= 4/10 or 2/5
m= 2/5
b is your y intercept
To get it, use 1 coordinate either from point A or B.
Let point A be the coordinates
y=mx + b
-3= 2/5(2) + b
b= - 3- 4/5
b= 16/5
Now we will find the equation of CD,
y=mx + b
y= (-5/2)x + b
Then get the coordinates of point C through midpoint equation,
(x1+x2) /2, (y1+y2) /2
(-3+7)/2, (2+6)/2
=C(2,4)
We will use this coordinates to find b,
y=mx+b
4=(-5/2)2+b
4+5=b
b=9
If we are finding the x intercept, y value should be 0.
0=(-5/2)x+9
0-9(2)/-5=x
x= 18/5
The x intercept of CD is (18/5,0)
2. The answer is (54,-128)

Given is a Right triangle PQR with angle Q = 90 degrees.
Given are sides PQ = 8 cm, QR = 15 cm, PR = 17 cm.
Side PR is the hypotenuse.
We can use formula for "sin" given as follows :-
[tex] sin(\theta)=\frac{Opposite}{Hypotenuse} [/tex]
For angle R, opposite side would be PQ.
[tex] sin(R)=\frac{PQ}{PR} \\\\
sin(R)=\frac{8}{17} \\\\
sin(R)=0.470588235 \\\\
R=sin^{-1}(0.470588235) \\\\
R = 28.07248694 \;\;degrees \approx 28.07 \;degrees [/tex]
For angle P, opposite side would be QR.
[tex] sin(P)=\frac{QR}{PR} \\\\
sin(P)=\frac{15}{17} \\\\
sin(P)=0.882352941 \\\\
P=sin^{-1}(0.882352941) \\\\
P = 61.92751306 \;\;degrees \approx 61.93 \;degrees [/tex]
Hence, R = 28.07 degrees and P = 61.93 degrees.
To solve the problem we must know about Trigonometric functions.

Solve for this equation for x round your number to the nearest hundredth 0.98=log x
Answers
Final answer:
To solve 0.98 = log x, you determine the number x for which 10 raised to the power of 0.98 equals x. Using a calculator, you find that x is approximately 95.50.
Explanation:
To solve the equation 0.98 = log x, we need to find the value of x such that when you take the common logarithm (base 10) of x, you get 0.98. A common logarithm is a logarithm with base 10, and the equation informs us that x is 10 raised to the power of 0.98 since y = log10(x) can be rewritten as x = 10y.
To find x, we can use the inverse operation of logarithm, which is exponentiation. We can express this process as follows:
x = 100.98
Using a calculator with exponentiation functionality, we enter the value of 0.98 and use the 10x function (sometimes labeled as INV or SHIFT followed by the LOG key).
The result is that x is approximately 95.50 when rounded to the nearest hundredth.

As a pendulum swings , the angle (theta) that it makes with the vertical changes through its swing. The force of gravity pulling on the bob is given by F=mg sin (theta), where g is equal to 9.8m/s^2. If the mass of the pendulum is 0.01 kg, what is the force pulling on the pendulum when it makes a 22.5 degree angle with the vertical?
Answers
Where m is the mass of the pendulum, g is the gravity, while θ is the angle between the pendulum and the vertical.
Therefore, m = 0.01 kg, g = 9.8 m/s² and θ = 22.5

B) Now, you can find the length of the hypotenuse:
Cos(α)=Adjacent/Hypotenuse
α=60°
Adjacent=41 feet
Hypotenuse=y
When you substitute these values into Cos(α)=Adjacent/Hypotenuse, you obtain:
Cos(60°)=41/y
