Find the equation of the line with slope m= 1/5
that contains the point (-10, 5).
Answer:
y = 1/5x +7
Step-by-step explanation:
The equation of a line is given by
y = mx+b where m is the slope and b is the y intercept
y =1/5 x + b
Substitute the point into the equation
5 = 1/5 (-10) +b
5 = -2 +b
Add 2 to each side
7 = b
y = 1/5x +7

ABC is an equilateral triangle. Find the angle of rotation that maps A to C. (A.) 360 (B.) 240 (C.) 0
Answer:
B. 240
Step-by-step explanation:
We are given an equilateral triangle. By definition, each angle of this triangle is equal to 60 degrees and the sides are all congruent.
We would like to rotate the triangle clockwise so that A maps exactly onto C. Since the internal angles are 60 degrees, when we turn the triangle one time to the right so that B is now at the top, we have rotated the entire figure 60 degrees.
Already, A is actually on C; however, none of the answer choices matches 60 degrees, so we realise that we want a multiple of 60 that will still ensure our triangle maps A to C. We notice that if we rotate the triangle three more times after that first rotation (so that's another 60 degrees, 60 degrees, and 60 degrees), we will obtain a position that is exactly what we want: A is on C!
Thus, the number of angles is 60 + 60 + 60 + 60 = 240.
The answer is B.
~ an aesthetics lover
Answer:
240
Step-by-step explanation:
Since this is an equilateral triangle, we can divide the circle into 3 pieces and the figure will look the same
360/3 = 120
Every rotation of 120, and the figure is identical
120, 240 ,360 will give an identical figure
Since we need to move point A to C we can move it 240 counterclockwise and point A will be at point C

Determine the measure of ∠DBC. answers: 1) 130° 2) 115° 3) 230° 4) 65°
Answer:
65 degrees
Step-by-step explanation:
65 degrees
it is 65 because of the vector relationship: 30 + 100 = 130. 130/2=65 degrees
Answer:
115
Step-by-step explanation:
The total circle is 360 degrees. The sum of the arcs of the circle is 360
Arc DC = 360 - Arc CB - Arc BC
DC = 360 -30-100
DC =230
Inscribed Angle =1/2 Intercepted Arc
<DBC = 1/2 CD
<DBC = 1/2 (230)
= 115

Why do you think we do not currently use the metric system here in the United States? Make sure to support your answer with information from the article:
Let's take a minute to think about measurements. To measure small lengths, we use feet and inches. Miles are used to measure long distances. If we need to measure liquids, cups and gallons are used. Need to know the temperature outside? Using degrees in Fahrenheit would be normal. The measurements we use are called imperial units. But did you know that there are only three countries who use imperial units? Unless you live in the United States, Liberia, or Myanmar, you use a different kind of measurement called the metric system. Think about that for a minute: everyone else in the world uses the metric system except for three countries.
However, scientists and mathematicians in the U.S. use metric measurements. In fact, they have been using the metric system for years. But if you are an ordinary American, you still use imperial units and measure your height in feet and inches, and your weight in pounds and ounces.
So if the rest of the world uses the metric system, why don't we? There are many reasons. Some people don't want to use a system they see as "foreign." Others, like people in the government, say that it would cost too much money to change everything over to the metric system. But did you know that we actually do use some metric units? Soda is sold in two-liter bottles, and liters are part of the metric system. Many people run in 5K races, and kilometers are part of the metric system. Also, a lot of our food nutrition labels are written in metric units. Don't you think this makes things a bit confusing? Why do we use metric units for a few things, but imperial units for everything else?
To fix this problem and use the same systems as the rest of the world, the U.S. has thought about changing to the metric system. In the 1970's and early 1980's, we actually came close to making the switch! Here's a little bit of history about the metric system:
In 1975, thanks to President Gerald Ford and Congress, the Metric Conversion Act was passed, which would have led to the metric system being the preferred system of weights and measures in the United States. This act created the United States Metric Board, which was abolished in 1982, by President Reagan.

A tangled web of sub-standard medieval weights and measurements was the British Imperial System, which was introduced to North America by the British Empire when it colonized the continent hundreds of years ago.
What is Imperial System?The imperial system of units, imperial system or imperial units is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
here, we have,
American units different from the metric system:
Distance is frequently measured in kilometers rather than miles, volume is frequently measured in liters rather than ounces, and clothing sizes are frequently measured in centimeters rather than inches.U.S. fasteners are frequently referred to as "standard." metric unit-based measurements, like millimeters. However, keep in mind that the United States is currently producing fasteners using the metric system.The imperial system, which uses measurements in feet, inches, and pounds, is used in the United States, as opposed to most other nations, which use the metric system, which uses measuring units like meters and grams.Obviously because of the British.

The Marauders fooseball team is improving with each game. The first game they
scored no points, but the second game they scored some goals. In their third game
they scored 8 more points than the second. Now in their last game they scored three
times as many points as their third. Altogether they scored 117 points!!! How many
points did they Marauders score in the third game?
Answer: 25 points
Step-by-step explanation:
From the question, we are told that the Marauders fooseball team is improving with each game and that in the first game theyscored no points, but the second game they scored some goals.
Let the number of points scored in the second game be y.
In their third game, they scored 8 more points than the second. This will be: y + 8.
Now in their last game, they scored three times as many points as their third. This will be:
= 3(y + 8)
= 3y + 24
Altogether they scored 117 points. This means that:
0 + y + y + 8 + 3y + 24 = 117
5y + 32 = 117
5y = 117 - 32
5y = 85
y = 85/5
y = 17
This means that in the second game, they scored 17 points.
Since we are told that in their third game they scored 8 more points than the second. This will be:
= 17 + 8
= 25 points

5.) 6 less than a number x x - 6
6.) One-half of n squared n² ÷ 2 or n²/2
Step-by-step explanation: In most cases, the first expression uses symbols that are commonly used in arithmetic or elementary math. As you advance into Algebra, the ÷ and × are rarely used in favor of / or fraction form like [tex]\frac{x}{4}[/tex] and [tex]\frac{x^{2} }{2}[/tex] for division. Parentheses replace × for multiplication, for example (25)(p)=25p to avoid confusion with x, commonly used as an unknown or variable.

An equilateral triangle has the same perimeter as a square whose side is 12.What is the length of each side of the triangle?
Answer:
Perimeter for rectangle/square is (length + width) x 2
12 + 12 = 24
24 x 2 = 48
So the perimeter is 48
divide 48 by 3 so it is split between 3 sides
48/3=16
so each side has a length of 16
Perimeter for triangle is adding up all the sides together
16 + 16 + 16 = 48 so the perimeter is the same as the square
16 is the answer
Hope this helps
Step-by-step explanation:
Answer:
The side length of the triangle is 16
Step-by-step explanation:
The perimeter of the triangle is
P = 3t since the sides are all equal
The perimeter of the square is
P = 4s since the sides are all equal
We are given the perimeter of the square is 12
P = 4*12
P = 48
We are told the perimeters are equal
48 = 3t
Divide by 3
48/3 = 3t/3
16 =t
The side length of the triangle is 16

The cross-section of the rectangular prism is a:
rectangleStep-by-step explanation:
When you take a cross-section of a rectangular prism, regularly you will obtain a rectangle because this was the base or the two-dimension figure that was used to form the three-dimension figure, in this case, the rectangular prism, the form of obtaining other figure is using how reference the square face, in that case, the cross-section would be a square, this happens because the cross-section is bind with the reference face. Possibly you think the cross-section in the figure doesn´t appear a rectangle, this happens by the perspective because we are looking at the rectangular prism with an inclination of 45°, but if the inclination was 90°, you would see a blue rectangle.
