Given that,
zahra earns $80 each day plus a 6% commission on her sale at an appliance store
zahra has $900 in sales
Find the commission amount
commission amount = 6 % of 900
[tex]commission\ amount = \frac{6}{100} \times 900\\\\commission\ amount = 54[/tex]
Zara earnings including commission amount = 80 + 54 = 134
Thus Zara earned $ 134 on friday including commission

-3x + 3y = 6
How many solutions can be found for the system of linear equations represented on the graph?
Solution:
Given system of equations are:
y = x + 2 ------ eqn 1
-3x + 3y = 6 -------- eqn 2
Solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
-3x + 3(x + 2) = 6
-3x + 3x + 6 = 6
-3x + 3x = 6 - 6
0 = 0
If we end up with the same term on both sides of the equal sign, then we have infinite solutions
Thus the system of equations has infinitely many solutions
A cube made out of lead has mass 12 grams. A side of the cube has length 1 cm. What would be the mass of a lead cube whose sides have length 1.5 cm?
Answer:
The mass of a lead cube whose sides have length 1.5 cm is 40.5 grams
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mass of the cube made out of lead = 12 grams
Side of the cube = 1 cm
2. What would be the mass of a lead cube whose sides have length 1.5 cm?
For answering the question, let's calculate the volume of the cube and then its density, this way:
Volume = Height * Width * Length
Volume = 1 * 1 * 1
Volume = 1 cm³
Let's recall the formula of the density:
Density = Mass/Volume, therefore:
Density of the lead = 12/1 = 12 gr/cm³
Now, let's calculate the volume of the second cube:
Volume = Height * Width * Length
Volume = 1.5 * 1.5 * 1.5
Volume = 3.375 cm³
Finally, let's calculate the mass, using the density of the lead we already know:
Density = Mass/Volume
12 = Mass/3.375
Mass = 12 * 3.375
Mass = 40.5 grams

Answer: You can use the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] (SEE EXPLANATION)
Step-by-step explanation:
Since the points are not written correctly, I will give you a general explanation about the procedure you should follow in order to find the distance between the two points.
By definition, the distance between two points can be calculated with the following formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
As you can observe, if you have two points:
[tex](x_1,y_1)\\\\(x_2,y_2)[/tex]
The steps you must follow in order to solve the exercise, are the shown below:
Step 1. You can substitute the values of [tex]x_1,y_1,x_2[/tex] and [tex]y_2[/tex] into the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)}[/tex].
Step 2. You must evaluate in order to find the distance between those two points.

Irrational:
sqrt. (3/8)
sqrt. (1/16)
sqrt. (10)
pi/2
Step-by-step explanation:
Rational numbers are parts of a whole, expressed as fractions, decimals, or percentages. They are finite, recurring, and real.
Irrational numbers have no end to their numbers, and there is no pattern to the numbers. Besides perfect square roots (like 4, 9, 16, 25, etc.), all square roots are likely irrational. Anything with pi is irrational.

The diameter of a sphere is 2,160 mm. The diameter of a second sphere is 7,520 mm. Approximately how many times larger is the volume of the second sphere than the volume of the first sphere?
Answer:
Approximately 42 times larger
Step-by-step explanation:
The diameter of a sphere is 2,160 mm.
The diameter of a second sphere is 7,520 mm.
To see how many times larger is the diameter of second sphere is than the diameter of the second sphere, we divide to get:
[tex]k = \frac{7520}{2160} [/tex]
[tex]k = 3.481[/tex]
To see how many times larger the volume is, we cube both sides
[tex] {k}^{3} = {3.481}^{3} [/tex]
This implies that
[tex] {k}^{3} = 42.181[/tex]
Therefore the volume of the second sphere is approximately 42 times larger
If CJ=2x+3, CT=53, and JT=9x+6, find JT
If CJ is given 2x + 3, CT is given 53 and JT is given 9x +6, then the value of x by the solving the equation is 4. So the value of JT is 42.
Explanation:To find the value of JT, we first need to establish the value of x.
Given the equation CJ + JT = CT or 2x + 3 + 9x + 6 = 53.
We can simplify that by adding 2x and 9x and 3 and 6 together to give us 11x + 9 = 53.
We then subtract 9 from both sides of the equation which gives us 11x = 53 - 9 or 11x = 44.
Then by dividing both sides of the equation by 11 we solve for x, which gives us x = 44 / 11 or x = 4.
Now we can substitute the value of x into the equation JT = 9x + 6.
Substituting 4 for x gives us JT = 9 × 4 + 6 or JT = 36 + 6.
So JT = 42.
Therefore, the value of JT is 42 when the value of x is 4.

In 2004, 520,000 acres of farmland in a region were devoted to growing nuts. By 2011, the number of acres used to grow nuts had increased to 850,000. Find the average rate of change in the number of acres in a region used to grow nuts from 2004 to 2011. The average rate of change was about acres per year. (Round to the nearest integer as needed.)
Answer:
see attachment
Step-by-step explanation:
The average rate of change in the number of acres used to grow nuts from 2004 to 2011 is approximately 47,143 acres per year when rounded to the nearest integer.
To find the average rate of change in the number of acres in a region used to grow nuts from 2004 to 2011, we can apply the formula for the rate of change, which is:
(Change in Quantity) / (Change in Time)
In this case, the quantity is the number of acres used for nut farming, and the time is the number of years between 2004 and 2011. The calculation is as follows:
Change in Quantity = Final value - Initial value = 850,000 acres - 520,000 acres = 330,000 acres
Change in Time = 2011 - 2004 = 7 years
Therefore, the average rate of change is:
Average rate of change = (330,000 acres) / (7 years) = 47,143 acres per year
Rounded to the nearest integer, the average rate of change is 47,143 acres per year.
A newspaper survey says that 424 people, or 53% of the people surveyed,
enjoy walking through the park. How many people were surveyed?
To find the total number of people surveyed when 424 people represent 53% of respondents, divide 424 by 0.53, which equals 800. Thus, 800 people were surveyed.
The question asks to determine the total number of people surveyed given that 53% of respondents enjoy walking through the park, and this represents 424 people. To find the total number of people surveyed, we set up a proportion where 53% (or 0.53) corresponds to the 424 people who enjoy walking in the park.
Using the formula for calculating percentages, we have:
Total people surveyed = 424 / 0.53
We perform the division to find the total number surveyed:
Total people surveyed = 800
Therefore, 800 people were surveyed.
It took me 3 hours to visit my friend in Maine, averaging a speed of 58 miles per hour. If it took me 15 minutes less to get back home, what was my average speed coming home?
Answer:
The average speed coming home was 63.27 miles per hour
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Speed from home to Maine = 58 miles per hour
Time of the first leg of the trip = 3 hours or 180 minutes
Time of the second leg of the trip = 15 minutes less = 180 - 15 = 165 minutes or 2 hours 45 minutes
2. What was my average speed coming home?
Let's calculate the distance from home to Maine, this way:
Speed = Distance/Time
Distance = Speed * Time
Distance = 58 * 3 = 174 miles
Now, let's calculate the speed of the second leg, as follows:
Speed = Distance/Time
2 hours 45 minutes = 2.75
Speed = 174/2.75
Speed = 63.27 miles per hour

Answer:
y = -5/7x -32/7
Step-by-step explanation:
To find the perpendicular line, it is the opposite opposite slope. this means that you change if it was positive or negative, and you flip the numerator and the denominator. so, because this slope is positive, you turn it to be negative. then you would switch the numerator and denominator, making the slope of the other line -5/7 (m). then you use y=mx + b to find the equation of the other line. you use (2,-6) and fill in the values to find be, so you would do
-6 = (-5/7)(2) + b so then you solve
-6 = (-10/7) + b
-32/7 = b
and then you fill in the y=mx +b to get y = -5/7x -32/7
