One month, a homeowner used 150 units of gas and 520 units of electric for a total of 54.20. The next month he used 210 units of gas and 405 units of electric for a total of 82.35.
I understand the 2 equations are
150g + 520e = 84.20
210g + 405g = 82.35
I dont understand how to get the value of g and e though, like someone said to use 7 to multiply against the first equation and -5 the second, but like where are we getting 7 and -5 from.
The solution to the system of equations is:
e = 0.109
g = 0.183
How to solve the system of equations?Defining the variables:
g = cost of the unit of gas.
e = cost of the unit of electricity.
Then the system of equations is:
150*g + 520*e = 84.20
210*g + 405*e = 82.35
Now we want to solve this.
To do so, we need to isolate one of the variables in one of the equations. Let's isolate g in the first one:
g = (84.20 - 520*e)/150
Now we replace that in the other equation so we get:
210*(84.20 - 520*e)/150 + 405*e = 82.35
Now we can solve this for e:
210*(84.20 - 520*e)/150 + 405*e = 82.35
(210/150)*(84.20 - 520*e) + 405*e = 82.35
117.6 - 728*e + 405*e = 82.35
117.6 - 323*e = 82.35
e = (117.6 - 82.35)/323 = 0.109
Then:
g = (84.20 - 520*0.109)/150 = 0.183
Then we can conclude that:
e = 0.109
g = 0.183

The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone. The formula for the surface area S of a right cone is S=πr2+πrl, where r is the radius of the base and l is the slant height. Find the height of the cone.
The height of this cone is 3( 1 + [tex]\frac{l}{r}[/tex] ). Which have the same volume and surface area.
Given that
The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone.
The formula for the surface area S of a right cone is S=πr2+πrl, where r is the radius of the base and l is the slant height.
To find
The height of the cone.?
So, according to the question
We have,
The surface area of the cone = The volume of the cone.
We know that
The surface area of the cone,
S = πr²+πrl
And,
The volume of the cone,
V = [tex]\frac{1}{3} \pi r^2h[/tex]
So, from question
The surface area of the cone = The volume of the cone
S = V
Now, put the all values,
πr²+πrl = [tex]\frac{1}{3} \pi r^2h[/tex]
πr(r+ l) = [tex]\frac{1}{3} \pi r^2h[/tex]
(r+l) = [tex]\frac{1}{3}[/tex] × [tex]\frac{\pi r^2h}{\pi r}[/tex]
(r+l) = [tex]\frac{1}{3}[/tex] × rh
[tex]\frac{3(r+l)}{r}[/tex] = h
h = 3( [tex]\frac{r}{r} + \frac{l}{r}[/tex] )
h = 3( 1 + [tex]\frac{l}{r}[/tex] )
So the height of this cone is 3( 1 + [tex]\frac{l}{r}[/tex] ).

Answer:
- 1 makes the equation true
Step-by-step explanation:
2s - 10 = - 12 ( isolate the term in s by adding 10 to both sides )
2s = - 2 ( divide both sides by 2 )
s = - 1
The integer ion in the solution set will make the equation true is -1. The correct option is a.
What are integers?Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers.
An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Given equation is
2s - 10 = - 12 ( isolate the term in s by adding 10 to both sides )
2s = - 2 ( divide both sides by 2 )
s = - 1

ridden a bike course that is 40 miles long. so far he has ridden 28 miles of the course. what percentage of the course has he ridden so far
So far, he has ridden 70% of the bike course.
Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".
The formula to get the percentage is:
Percentage = (Value / Total Value) × 100
If the total value of the bike course is 40 miles and the value which the percentage we are looking for is 28 miles, evaluating the equation:
Percentage = (Value / Total Value) × 100
Percentage = (28 / 40) × 100
Percentage = (0.7) × 100
Percentage = 70
Therefore, he has ridden 70% of the bike course so far.

Answer:
frequency =12 and mass x (kg)=20<=x<30Triangle UML has coordinates U (-3, -4), M(-1, -1) , and L(-2, -5). If the triangle is translated 5 units up and 1 unit left to form triangle U’M’L’, what will be the coordinates of L’?
After the translation the coordinates of L' are (-3, 0) for the new triangle of U’M’L’.
What is defined as the translation?In geometry, translation refers to a function which moves an object a specified distance. The object is not elsewhere altered. It is not rotated, mirrored, or resized.Every location of the object should be moved within the same direction for the same distance during a translation.When performing a translation, this same initial object is referred to as the pre-image, and also the object just after translation is referred to as the image.The coordinates of triangle are-
U (-3, -4), M(-1, -1) , and L(-2, -5).
The triangle is translated 5 units up and 1 unit left to its original place.
Thus, for the 5 units up translation 5 units will get added to the y-coordinates.
New y-coordinate of L' is -5 + 5 = 0.
For 1 unit left , 1 units will get reduced from the original x-coordinate.
New x-coordinate = -2 - 1 = -3
Thus, the new coordinates L' becomes (-3, 0).

The standard deviation of the distribution = 1.5°F
Given that the distribution of daily high temperature is approximately normal.
Population mean, [tex]\mu[/tex] = 86°F
Also approximately 95% of all daily high temperatures are between 83°F and 89°F.
So here [tex]X_1[/tex] = 83°F and [tex]X_2[/tex] = 89°F
We have the z - statistic ,
[tex]z=\frac{x-\mu}{\sigma}[/tex]
where [tex]\sigma[/tex] is the Standard deviation.
For 95% probability, the z-value for normal distribution is 1.96.
As we consider the positive z-value, take X = [tex]X_2[/tex] = 89°F
So, [tex]z=\frac{x-\mu}{\sigma}[/tex]
⇒ [tex]\sigma = \frac{x-\mu}{z} = \frac{89-86}{1.96} =1.53[/tex] ≈ 1.5°F
