Answer:
Take the square root of each side
D (x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
Step-by-step explanation:
We have
(x+b/2a) ^2 = (b^2-4ac)/ 4a^2
We need to take the square root of each side to continue to isolate x
(x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
I hope thats right

im just tryna fill space for the 20 required character in a question please help
Answer:
125.6m^2
Step-by-step explanation:
Let R be the greater radius and r be the smaller radius
Area of the sidewalk = R^2 - r^2 - This can be the expression
= 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
= 40
= 3.14 x 40
Is it 13 x 6??? or 6 x 8?? 13 x 8????????????????
Please help! And explain you answer!
Answer:
It is 6x13
Step-by-step explanation:
you would multiply the length which is 13 times the height. The 8 is slanted so you wouldn’t multiply that. The 6 is a straight line so that is the correct height
Answer:
13*6=78 cm^2
Step-by-step explanation:
8 is redundant in this question, it's just there to throw you off and you don't need it.
To get the area of a parallelogram, multiply the base by the height.
13*6=78

Write two division expressions that have the same value as 36.8÷2.3.
You spin a spinner, flip a coin, then spin the spinner again. Yind the probability of spinning a 3, flipping heads, then spinning a 4 Write your answer as a fraction in simplest form
Answer:
1/200
Step-by-step explanation:
P(Spinner lands on a 3) = 1/10
P(Heads) = 1/2
P(Spinner lands on a 4) = 1/10
1/10 * 1/2 * 1/10 = 1/200

Answer: The answer is 1125 cm
Step-by-step explanation:
By using the equation Area=1/2(b*h) (b=base, h=height)
By using this you can see that the area is 1125 cm
Area=1/2(30*75)= an area of 1125 cm
Answer:
1125 is the answer

Which measure of spread is the most appropriate for the data set represented by the graph?
A. range
B. quartiles
C. interquartile range
D. mean absolute deviation
E. either range or interquartile range
The most appropriate for the data set represented by the graph is mean absolute deviation.
What is Mean absolute deviation (MAD)?It is a measure of variability or variation that indicates the average distance or average absolute distance between each data point or data value and the mean of a data set
We can calculate the variability of a data set by different measure thay include range, interquartile range, mean absolute deviation, standard deviation, etc.
Quartiles or ranges may be useful but they are limited as they tend to skip a lot of data in the group.
While, absolute deviation can help us get a more representative idea of spread for a data set like the one given in this question, where the elements have close difference.
Hence, the most appropriate for the data set represented by the graph is mean absolute deviation.

The models below are shared to show 4/8 and 2/4. What do the models show about these fractions
Answer:
I do not see the model, but based on what you are telling me, I believe that both the fractions are equal is what is being shown. They are, in other words, equivalent fractions
Answer:
The models show that both fractions are equivalent.
Step-by-step explanation:
The model shows they have the same value but are just divided in different ways. Also, if you reduce 4/8 you get 2/4 meaning they are equivalent.
NOTE* We cannot see the models.

20 + 5z
In the expression, what does the second term represent?
Finn's earnings at the end of the week
The number of crates of oranges Ellie sold
Ellie's earnings at the end of the week
The number of crates of oranges Finn sold
Answer:
Finns earning at the end of the week.
Step-by-step explanation:
It is asking for the second TERM which is 5z which is the price Finn sells them for ($5) times the amount he sells (X) which equals the earnings he makes.

how many sixth grade students take notes with a pencil?
I think the answer would be 40
Answer: Hello, There! your Answer is Below
40 Is your Answer
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with XStep 3:
From step 1 above,$80=100
Step 4: Similarly, x=50
Step 5: This results in a pair of simple equations:This results in a pair of simple equations:
$80=100\(1)
$x=50(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
80/x = 100%/50%
Step 7: Again, the reciprocal of both sides gives
x/80 = 50/100
x=40$
Therefore, 50%of 80i s 40
