Which equation represents a line which is parallel to the line by – 7x = 24?:A) y=7/6x+3B) y=6/7x-2C) y=-7/6x-1D)y=-6/7x+7
We have the equation 6y-7x=24, and want to know what of the options represents a line parallel to that one.
First we need to write our equation in the form of the options:
[tex]\begin{gathered} 6y-7x=24 \\ 6y=7x+24 \\ y=\frac{7x+24}{6}=\frac{7x}{6}+\frac{24}{6} \\ y=\frac{7}{6}x+4 \end{gathered}[/tex]Now, we know that two lines are parallel if and only if they slopes are equal, so the slope of our line is 7/6 and the option that has the same slope is the option A.
So te correct answer is the option A

What is the intensity of an earthquake in Hawaii
which measured 3.92 on the richter scale?
Use the formula M = log(i/s)
S= 1 micron
- 7,943 microns
- 6904 microns
- 8318 microns
- 2818 microns
8318 microns is the intensity of an earthquake in Hawaii.
What is Richter scale?The Richter scale was originally developed to measure the magnitude of moderate earthquakes (magnitude 3 to magnitude 7) by assigning numbers so that the magnitude of one earthquake can be compared to another. This scale was developed for the Southern California earthquake recorded by the Wood He Anderson seismograph whose epicenter was less than 600 km (373 mi) from the seismometer location. However, today's seismometers can be calibrated to calculate the Richter magnitude, and modern methods of measuring earthquake magnitude are designed to give results consistent with those measured using the Richter scale. Developed.
The magnitude of an earthquake is determined using the logarithm of the amplitude (height) of the largest seismic wave, calibrated to scale by the seismograph.
Using the formula,
[tex]M = log \frac{i}{s}\\ 3.92 = log\frac{i}{1 micron} \\10^3.92 = \frac{i}{s} \\i = 8318[/tex]

We are to look for lines that are not parallel to y=3x + 4
Comparing the above equation with y=mx + b, the slope(m) = 3
Equations of lines are said to be parallel, if they have the same slope
So, we need to re-write each equation in the slope-intercept form to see which is NOT parallel to the given equation

Max has 15-foot long piece of plastic pipe. He wants to cut it into four equivalent pieces to make corner flag poles for the soccer field. What should be the length of each flagpole that will be cut?
Answer:
3.75 feet
Explanation:
To know the length of each flagpole, we need to divide 15 (the total length of the piece of plastic pipe) by 4 because he wants 4 pieces. Then:
15 ÷ 4 = 3.75 feet
Then, each flagpole should have a length of 3.75 feet.

What is the average rate of change of the function f(x) = x^2 – 2x + 4 over the interval –2 ≤ x ≤ 3?
The rate of change of a function is the increase or decrease that a function experiences as the independent variable changes from one value to another.
The corresponding equation of the average rate of change is:

A factory makes candles. Each candle is in the shape of a triangular prism, as shown below. If the factory used 14,700 cm^3 of wax,how many candles did the factory make?
Answer:
Explanation:
Step 1
First, we find the volume of one the triangular prism shaped candles.
The volume of a prism is calculated using the formula:
[tex]V=\text{ Cross-Sectional Area}\times\text{ Length}[/tex]The cross section of the prism is a triangle with:
• Base = 10cm
,• Height = 7cm
Length of the Prism = 6cm
Therefore:
[tex]\begin{gathered} V=\frac{1}{2}bh\times L \\ =\frac{1}{2}\times10\times7\times6 \\ =210\;cm^3 \end{gathered}[/tex]The volume of one of the candles is 210 cubic cm.
Step 2
Next, divide the volume of wax used by the factory by the volume of one candle.
[tex]\text{Number of candles made}=\frac{14700}{210}=70[/tex]Which of the following Platonic solids is made from squares? Check all thatapply.A. icosahedronB. cubec. tetrahedronD. octahedronE, hexahedronF. dodecahedron
From the information on platonic solids, we can say that cube is the only platonic solid that is made from squares. Thus, option B is correct.
Platonic solids, also referred to as regular solids or regular polyhedrons, are the types of solids that have identical faces composed of congruent regular convex polygons.
A platonic solid can be defined as a 3D shape where each face is similar to a regular polygon and consists of same number of faces that meet at each vertex of the polygon.
There are 5 different types of platonic solids that are -
Tetrahedron - A tetrahedron is referred to as a triangular pyramid in geometry. The tetrahedron comprises of 4 triangular faces, 6 straight edges, and 4 vertex corners.Cube - A cube can be defined as 3D solid object with 6 square faces and consists of the sides that are of the same length. The cube is also called as a regular hexahedron which is a box-shaped solid with 6 equivalent square faces.Octahedron - An octahedron is in fact, a polyhedron consisting of 8 faces, 12 edges, and 6 vertices and at each of the vertices, the 4 edges coincide. The faces of an octahedron are shaped in the form of an equilateral triangle.Dodecahedron - A dodecahedron is referred to as a platonic solid comprising of 12 sides and 12 pentagonal faces. Icosahedron - An icosahedron is a platonic solid with 20 faces, 30 edges, and 12 vertices. The shape of an icosahedron consists of equilateral triangle faces.Thus, from the above information on platonic solids, we can say that cube is the only platonic solid that is made from squares. Thus, option B is correct.

For 97.1 seconds, a remote-controlled helicopter flew at an altitude of 3 meters and a constant velocity of 19.0 meters per second to the west. During this time, how far did the helicopter fly?
The relationship between time, distance and velocity is:
[tex]v=\frac{d}{t}[/tex]In this case, we need to find the distance, d
We can solve for d:
[tex]v=\frac{d}{t}\Rightarrow d=v\cdot t[/tex]The velocity of flight is v = 19 m/s and the time of flight is t = 97.1s
Then:
[tex]d=19\frac{m}{s}\cdot97s[/tex][tex]d=1844.9m[/tex]The answer is 1844.9m

Given data -
Total number of members in U.S senate = 100
Let the number of republicans in U.S senate be x members
As republicans outnumber democrats by six,
Therefore, number of democrats = (x+6) members
According to the given data,
