11 students in the Environmental club represent 4% of the students in the seventh grade. How many students are in the seventh grade?
Answer:
275
Step-by-step explanation:
The best way to do this is to set it up in this equation:
4/100 = 11/x, in this, the 4 over 100 represents 4% out of 100%. The 11 over x represents the 11 students out of x amount of students. With this equation, you cross multiply to get 4x = 1100. Then you divide both sides by 4 to get x by itself. This will give you x=275
After solving the equation, the total number of students in the 7th grade is 275.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data mentioned in the question,
Total number of students in the Environmental club = 11
Percentage of students from 7th grade = 4%
Let the total number of students in 7th grade be x
Then, the equation according to the statement will be,
4% of x = 11
So,
x = (11 × 100)/4
x = 275

1. Find x
2 find ab
3.Find bc
AC = 46
AB + BC = AC
(4x + 7) + (3x + 4) = 46
4x + 7 + 3x + 4 = 46
(4x + 3x) + (7 + 4) = 46
7x + 11 = 46
7x = 46 - 11
7x = 35
x = 35/7
x = 5
AB = 4x + 7
AB = 4(5) + 7
AB = 20 + 7
AB = 27
BC = 3x + 4
BC = 3(5) + 4
BC = 15 + 4
BC = 19

There are two approaches to this question.
Approach 1:
We can compute the slope of a line by calculating its mean variation, the rise over run. Mathematicaly:
[tex]a=\frac{\Delta y}{\Delta x}[/tex]
The two points we have are [tex]P1 = (1,3)[/tex] and[tex]P2 = (4,3)[/tex]. Plugging the values into the expression we get
[tex]a=\frac{3-3}{4-1} \\a=0[/tex]
Therefore, the slope of the line is zero.
Approach 2:
The slope of the line is given by the angle [tex]\alpha[/tex] it makes with the X axis, in other words,
[tex]a = tan(\alpha)[/tex]
Note that the angle the line makes is exaclty zero. Therefore:
[tex]a= tan(0)\\a=0[/tex]
Again, we get that the slope of the line is zero.
In general, the slope of any horizontal line will always be zero.

A transformation that does not change the size or shape of a geometric object is known as which of the following?
A an identity transform
B a complete mapping
C a congruent movement
D a rigid motion
Answer:
c
Step-by-step explanation:
The transformation that does not change the size or shape of a geometric object is known as an identity transform option (A) an identity transform is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a statement:
A transformation that does not change the size or shape of a geometric object is known as:
The transformation is known as an identity transformation because in the identity transformation the shape and size of the object remain the same or unchanged.
Thus, the transformation that does not change the size or shape of a geometric object is known as an identity transform option (A) an identity transform is correct.

Step-by-step explanation:
The results of a recent survey showed that the average cost to rent a car for a week is $276. If the standard deviation is $60,
find the Z-score for a weekly rental of $423.00?
a. 2.45
B. 4.6
C. 7.05
D. -1.88
The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
Given the average cost to rent a car for a week is $276
And the standard deviation is $60
To determine the Z-score for a weekly rental of $423.00
Here,
ц = 276
σ = 60
X = 423
⇒ z-score = (X-ц )/σ
Substitute the values,
⇒ z-score = (423 - 276)/60
⇒ z-score = 147/60
⇒ z-score = 2.45
Hence, the z-score for a weekly rental is 2.45.
