The number of students in the school are represented by percentages
The number of students in the school is 1600
Let the number of students in the school be n.
So, the equation from the question is:
[tex]\mathbf{10\% \times n = 160}[/tex]
Divide both sides by 10%
[tex]\mathbf{n = \frac{160}{10\%}}[/tex]
Express 10% as decimal (0.10)
[tex]\mathbf{n = \frac{160}{0.10}}[/tex]
[tex]\mathbf{n = 1600}[/tex]
Hence, the number of students in the school is 1600

in triangle DEF, the measure of angle Eis 30 and the measure of angle F is 45. What is the measure of angle D?
Answer:
angke D = 105°
Step-by-step explanation:
All triangles add up to 180°. 30+45=75 180-75=105
In triangle DEF, the measure of angle D is 105°.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
In triangle DEF,
Value of ∠ E = 30°, ∠ F = 45°.
Let the value of ∠ D is x°.
Since, the sum of the angles of a triangle is 180°.
Apply this property in triangle DEF,
30 + 45 + x = 180
75 + x = 180
x = 180 - 75
x = 105
The value of ∠ D is 105°.

Are the following lines parallel, perpendicular, or neither? y=−43x−5 and y=34x−5
9514 1404 393
Answer:
as written: neither
as fractions: perpendicular
Step-by-step explanation:
The x-coefficients of -43 and 34 are unrelated, so the lines are neither parallel nor perpendicular.
__
If you intend the equations to be ...
y = -4/3x -5
y = 3/4x -5
then the x-coefficients are opposite reciprocals, and the lines are perpendicular.

What's the solution: 4 (6x - 4) = 8 (3x - 2)
Answer: Simplifying
4(6x + -4) = 8(3x + -2)
Reorder the terms:
4(-4 + 6x) = 8(3x + -2)
(-4 * 4 + 6x * 4) = 8(3x + -2)
(-16 + 24x) = 8(3x + -2)
Reorder the terms:
-16 + 24x = 8(-2 + 3x)
-16 + 24x = (-2 * 8 + 3x * 8)
-16 + 24x = (-16 + 24x)
Add '16' to each side of the equation.
-16 + 16 + 24x = -16 + 16 + 24x
Combine like terms: -16 + 16 = 0
0 + 24x = -16 + 16 + 24x
24x = -16 + 16 + 24x
Combine like terms: -16 + 16 = 0
24x = 0 + 24x
24x = 24x
Add '-24x' to each side of the equation.
24x + -24x = 24x + -24x
Combine like terms: 24x + -24x = 0
0 = 24x + -24x
Combine like terms: 24x + -24x = 0
0 = 0

A car rents for $180 per week plus $0.25 per mile. Find the cost of renting this car for a two week trip of 400 miles for a family of 4.
9514 1404 393
Answer:
$460
Step-by-step explanation:
If w is the number of weeks the car is rented, and m is the number of miles driven, the cost structure tells you the rental cost (c) is ...
c = 180w +0.25m
For w=2 and m=400, this becomes ...
c = 180·2 +0.25·400 = 360 +100 = 460
The cost of the 2-week rental will be $460.

The family size is irrelevant to the cost.

Part B: Are the two figures congruent? Explain your answer.
Part A: (x, y) ⇒ (x, y -3) is the overall transformation
Part B: Yes both figures are congruent.
What is transformation?A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
Part A:
From the given figure it is clear that the vertices of preimage are A(-4,4), B(-2,2), C(-2,-1) and D(-4,1).
The vertices of image are A'(4,1), B'(2,-1), C'(2,-4) and D'(4,-2).
1st transformation - reflection across y-axis
Sign of x coordinate gets changed
(x, y) ⇒ (-x, y)
A(-4,4) ⇒ (4, 4)
B(-2,2) ⇒ (2, 2)
C(-2,-1) ⇒ (2, -1)
D(-4,1) ⇒ (4, -1)
2nd transformation - 3 step down
Y = y - 3
(x, y) ⇒ (x, y -3)
(4, 4) ⇒ A'(4, 4 - 3) = (4, 1)
(2, 2) ⇒ B'(2, 2 - 3) = (2, -1)
(2, -1) ⇒ C'(2, -1 - 3) = (2, -4)
(4, 1) ⇒ D'(4, 1 - 3) = (4, -2)
(x, y) ⇒ (-x, y -3) is the overall transformation

The Miami Heat scored 79 points. This was 13 points less than the Chicago Bulls. How many points did the Chicago Bulls score?
Write an equation and solve.
Answer:
92
Step-by-step explanation:
Miami scored 79 points which was 13 LESS than Chicago.
So, Miami = Chicago - 13, (change Miami to their score)
79 = Chicago - 13 (add 13 to both sides to isolate Chicago and find answer)
92 = Chicago
Equation: 79 = Chicago - 13
Hich statements about the function f are true? Check all that apply. The domain of f(x) is {all real numbers}. The range of f(x) is {all real numbers}. The domain of f(x) is {x| x > 0}. The range of f(x) is {y| y > 0}. f(2) = 4 f(2) = 2(x + 3)
Answer:
A. The domain of f(x) is {all real numbers}.
B. The range of f(x) is {all real numbers}
E. f(2) = 4
Explanation
Find the graph attached.
The domain of a function is the value of the input variable x for which the function f(x) exists. Given the function
f(x) = 1/2 x + 3
The function will exist on all values of x (either positive or negative).
The domain can be said to exist on all real values. If you look at the graph, we will see that the line tends to both negative infinity and positive infinity. Hence the domain can be represented according to the set notation:
DOMAIN: (-∞, ∞)
The range is the set of output value y for all input variable x. The output value y will also exist on all real values because, no matter the value of x imputed in the function, we will always get a finite value as the output. Hence the range of the function is denoted by the set notation:
RANGE: (-∞, ∞)
Next is to get f(2).
To get f(2), we will set the input value as 2 and calculate for the output value as shown:
f(2) = 1/2(2) + 3
f(2) = 1+3
f(2) = 4
Hence the following are true of the function:
The domain of f(x) is {all real numbers}.
- The range of f(x) is {all real numbers}
- f(2) = 4

And employee earns 1.5 times the hourly rate for each hour worked in a week over 40 hours. One weeks employee worked 46 hours and earned $588 before deductions. What is the employees hourly rate?
Answer:
12 dollars per hour upto 40 hours
18 dollars per hour after 40 hours
Step-by-step explanation:
Let the hourly rate of the employee i.e. amount earned by the employee = [tex]x[/tex] dollars per hour
As per question statement, hourly earning after 40 hours = [tex]1.5x[/tex]
Given that employee worked for 46 hours.
Writing equation:
[tex]40x+6(1.5x)=588\\\Rightarrow 40x+9x=588\\\Rightarrow 49x =588\\\Rightarrow \bold{x = 12}[/tex]
So, the hourly rate of the employee up to 40 hours is 12 dollars per hour.
And hourly rate of the employee after 40 hours = [tex]12\times 1.5 = 18[/tex] dollars per hour

A 1-litter bottle of soda cost $0.99 and a 2-litter bottle of soda costs $1.59. Which of these statements will help a shopper decide which bottle is the better buy?
Answer:
The 2-litter bottle is the better buy because it is less expensive than two of the 1-litter bottles of soda.
Step-by-step explanation:
You know that a 1-litter bottle of soda cost $0.99. So, if you want to buy 2 liters of soda you can perform the following calculation:
2 bottles of a 1-litter bottle of soda * price of a 1-litter bottle of soda
2*$0.99= $1.98
So, if you want to buy 2 liters of soda by acquiring 2 1-litter bottle of soda, you must pay $ 1.98.
On the other side, you know that a 2-litter bottle of soda costs $1.59.
Comparing, you can see that the price of 2 1-liter bottles is more expensive than the price of a 2-liter bottle, with a difference of:
$1.98 - $1.59= $0.39
In others words, the 2-litter bottle is the better buy because it is less expensive than two of the 1-litter bottles of soda.
