3. Michelle looks at the equation below
and says there is no solution. Is she
correct? Explain.
-6x - 30 = 6x – 30
Answer:
there is a solution but x will equal 0
Step-by-step explanation:
-6x-30=6x-30
combine -6x and 6x
-12x -30=-30
add 30 and -30
-12x=0
since -12 don't equal 0 then x will equal 0
so the final answer is x=0

You know that the rose garden is 20% of the total garden. What is 20% written as a ratio?
Answer:
20:100
Step-by-step explanation:
We know that percentages are out of 100. The rose garden is 20 percent of the garden. Which is 20 percent/100 percent. A ratio says how much of one thing there is compared to another thing. Therefore we are comparing 20:100. You can also simplify this ratio to 1:5
Answer:20:100

Step-by-step explanation:
john has 12 pounds of dog food and is going to separate it into 3/4 pound portions how many portions will he get
Answer:
John will get 16 3/4 pounds-units of dog food.
Step-by-step explanation:
The total amount of portions of dog food is obtained by dividing the total amount of dog food, measured in pounds, by the amount of dog food per portion, measured in pounds per unit:
[tex]n = \frac{12\,pd}{0.75\,\frac{pd}{unit} }[/tex]
[tex]n = 16\,units[/tex]
John will get 16 3/4 pounds-units of dog food.
Emmett gathered some data to compare the monthly cost of renting a one-bedroom apartment in Dallas and Austin. The data collected for the monthly cost of renting a one-bedroom apartment in Dallas is shown below.
$994 $1,322 $1,075 $1,189 $1,172
$1,465 $1,215 $930 $1,090 $1,288
The data collected for the monthly cost of renting a one-bedroom apartment in Austin is shown below.
$1,450 $1,400 $1,375 $1,389 $1,296
$900 $1,250 $1,100 $950 $1,495
Select ALL the statements that are true about the Austin Data.
This city's data had the higher interquartile range of the two cities by $87.
This city's data had the higher median monthly apartment cost of the two cities by $155.
this city's data had the lower average apartment cost because the mean was $86.50 less than that of the other set of data.
This city's data had the greater variability among monthly apartment costs because the standard deviation was $49.13 more than that of the other set of data.
Answer:
The correct options are;
a) The city's data has the higher median monthly apartment cost of the two cities by $155
b) The city's data had the greater variability among monthly apartment costs because the standard deviation was $49.13 more than that of the other set of data
Step-by-step explanation:
The given data for the cost of renting a one-bedroom apartment in Dallas is presented as follows;
$994, $1,322, $1,075, $1,189, $1,172, $1,465, $1,215, $930, $1,090, $1,288
Which can be arranged in increasing order and analyzed to find the interquartile range, mean and standard deviation using Microsoft Excel as follows;
$930, $994, $1,075, $1,090, $1,172, $1,189, $1,215, $1,288, $1,322, and $ 1,465
The first quartile, Q₁ = $1,054.75
The third quartile, Q₃ = $1,296.5
The interquartile range = Q₃ - Q₁ = $241.75
The median = $1,180.5
The average monthly cost = $1,174
The standard deviation of the sample = $159.9597
The given data for the cost of renting a one-bedroom apartment in Austin is presented in increasing order using Microsoft Excel as follows;
$900, $950, $1,100, $1,250, $1,296, $1,375, $1,389, $1,400, $1,450, $1,495
The interquartile range, mean and standard deviation are found using Microsoft Excel as follows;
The first quartile, Q₁ = $1,062.5
The third quartile, Q₃ = $1,412.5
The interquartile range = Q₃ - Q₁ = $1,412.5 - $1,062.5 = $350
The median = $1,335.5
The average monthly cost = $1,260.5
The standard deviation of the sample = $209.0945
The difference in the median cost of the two cities is $1,335.5 - $1,180.5 = $155
Therefore, the Austin's city data has the higher median monthly apartment cost of the two cities by $155
b) The difference in the sample standard deviation of the two cities is $209.0945 - $159.9597 = $49.13476
Therefore, the Austin city data had the greater variability among monthly apartment costs because the standard deviation was $49.13 more than that of the other set of data.
Answer:
This city's data had the higher median monthly apartment cost of the two cities by $155.
This city's data had the higher interquartile range of the two cities by $87.
This city's data had the greater variability among monthly apartment costs because the standard deviation was $49.13 more than that of the other set of data.
Step-by-step explanation:
Austin Mean: 1335.5
Dallas Mean: 1180.5
Interquartile Range (Austin): 300
Interquartile Range (Dallas): 213
Standard Deviation (Austin): 209.0945
Standard Deviation (Dallas): 159.9597

Change the amount of teachers to be 10.
6x < -96
solve for x
Answer: Anything greater then -16 (EX: -15, -14)
Work: This is a One-Step Inequality equation, meaning you just need to divide. You need to get x by itself, so you divide the 6 on both sides, but since there is a negative, you have to flip the sign. So, the answer is x > -16.
Check: 6(-15) > -96; -90 > -96 < It's correct.

What is a lever? On which principle does it work?
Is velocity ratio of a machine affected by applying
Answer:
A lever is a bar that turns on an unmoving point called a fulcrum. When you push or pull on one end of the bar that pressure is called the force. The object that is lifted on the other end is called the load.
Step-by-step explanation:
Let a machine overcome a load L by the application of an effort E. In time t, let the displacement of effort of dE ad the displacement of load be dL.
Work input =Effort× displacement of effort
=E×dE
Work output =Load× displacement of load
=L×dL
Efficiency=Work inputWork output
=E×dEL×dL=EL×dEdL
=EL×dE/dL1
But Effort(E)Load(L)=M.A.
and dLdE=V.R.
∴Efficiency η=V.R.M.A. or M.A.=V.R.×η
Thus, the mechanical advantage of a machine is equal to the product of its efficiency and Velocity Ratio.

Two lines have a slope of 3 and different y-intercepts how many solutions will this system have
Answer:
0 solutions / no solutions
Step-by-step explanation:
If two lines have the same slope but different y-intercepts, it means that they are parallel.
For example, we have two lines:
y = x
y = x + 1
Both lines have the same slope of 1, but different y - intercepts. Because each equation increases the x and y at the same right (slope) but started at different points, the two equations will never touch.
It's similar to two runner who run at the same pace. If one runner started 50 meters ahead, that runner will always be ahead 50 meters (y-intercept) because they both run at the same rate.
PLEASE HELP the graph for the equation y equals negative 2x + 1 shown below. if another equation is graphed so that the system has no solution which equation could that be?
