Answer:
Length = 12
Width = 6
Step-by-step explanation:
Width = 6 miles less than length;
L = L
W = L - 6
Area = 72 ft²
Area = Length * width
Area = (L * L-6)
Area = L² - 6L
-
L² - 6L = 72
L² - 6L - 72 = 0
L² - 12L + 6L - 72 = 0
L(L - 12) +6(L - 12) = 0
L = 12 or L = - 6
L cannot be negative
Width = L - 6
Width = 12 - 6 = 6
Hence,
Dimension of rectangle :

Answer:
y = -(1/7)x + 1
Step-by-step explanation:
[tex]3x + 21y = 21 \\ 21y = 21 - 3x \\ y = \frac{21 - 3x}{21} \\ y = 1 - \frac{1}{7} x \\ y = - \frac{1}{7} x + 1[/tex]

Mike has a 32 ounce drink. He drinks 8 ounces. Select the percent of ounces Mike has left from his drink
Answer:
75%
Step-by-step explanation:
the percentage amount of the drink that mike drank is calculated by dividing the total drink by the amount drank. In this case that is 8/32 which gives us 0.25 or 25%.
In order to find the amount Mike has left you simply subtract the amount drank from the 1 as 1 is equal to 100% or the amount mike had at the begining. In this case 1-0.15= 0.75 or 75%.
OR
you can also solve this by subtracting tha amount drank by the total then dividing the remaining drink by the total amount of the drink. In this case that would look like:
32-8= 24
24/32= 0.75

Answer:
I'm not sure what 15y3 is, but I'll take a guess.
If the only numbers are 15, 3, and -40, then the greatest common factor is 1.
If the only numbers are 15 and 3, then it's three.
If the only numbers are 15 and -40, it would be 5.

What is the mean of the data set?
47, 25, 43, 33
Answer:
The mean is 47
Step-by-step explanation:
First, you want to add up all of the numbers.
47 + 25 + 43 + 33 = 148
Now, you want to divide what you got by how many numbers there are.
148/4 = 37
The mean is 47
Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.
Calculations for the mean of a data set: Mean of the terms given in a data set is represented by the avarage of the terms.
Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]
Total of the terms given in the the data set = 47 + 25 + 43 + 33
= 148
Number of terms in the data set = 4
Substitute these values in the expression of the mean,
Mean = [tex]\frac{148}{4}[/tex]
= 37
Therefore, mean of the data set given in the question is 37.

The six sides of a number cube are labled 1,2,3,4,5,6, . You flip a coin and roll the number cube what is the probability that you land on tails and get a number less than 3.
Answer:
1/6 or 16.67%
Step-by-step explanation:
The probablility for the coin is 50% and the probablility for the cube is 2/6 or 1/3 aka 33.3%. You need to multiply these together to figure out the percentage so 1/2 time 1/3 is 1/6.
Which is the correct equation for a line that has a slope of 2 and passes through the point (-1, -5). Use the graph below or graph paper if needed.
PLEASE HELP ASAP
A.y = 2x - 5
B.y = 2x + 5
C.y = 2x - 3
D.y = 2x + 3
9514 1404 393
Answer:
C. y = 2x - 3
Step-by-step explanation:
The y-intercept (b) can be found from ...
y = mx + b
y - mx = b . . . . . subtract mx
Here, you are given (x, y) = (-1, -5) and slope m = 2.
b = -5 -2(-1) = -5+2 = -3
The correct equation is ...
y = 2x -3 . . . . . matches choice C
_____
On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

Cody increased the amount of money he saves each week from $40 to $75. By
what percentage did Cody increase the amount of money he saves?
Answer:
So Cody increase his savings by 87.5%
Step-by-step explanation:
We are given Cody's original savings = $40
We are given his new savings total = $75
Now, in order to find out the percentage we have to first find out by how much did he increase his savings:
Increase in savings = $75 - $40 = $35
So now we have the increase in savings we can find out the percentage:
[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]
Now we plug in our values that we found:
[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]
So Cody increase his savings by 87.5%

why is it important for jews to understand the characteristics of God
Answer:
To conclude, the characteristics of God provide a foundation by which Jews can look up to and mimic behaviour and develop good morals. They can come to understand and appreciate God, particularly as he is unseen, and this allows for them to be able to believe without question e.g. God is all knowing. G-d is all knowing and has a purpose for the world. This gives people faith to believe in God and wait for the Messianic Age to come, and have patience in God’s plan. However, it can be argued that there is no real point in having being taught characteristics of a being which can not be seen. With characteristics, some may argue that the concept of God can still not be understood, and the idea is unclear, particularly as the descriptions are supposedly by God himself, in which many Jews do not believe, as they are culturally and ethnically Jewish, rather than religiously Jewish.
