In 2010, 465 students went to a certain school. In 2014, 372 students went to the same school by what percent did the number of students decrease
Answer:
20% decrease
Step-by-step explanation:
New value =
465 - Percentage decrease =
465 - (20% × 465) =
465 - 20% × 465 =
(1 - 20%) × 465 =
(100% - 20%) × 465 =
80% × 465 =
80 ÷ 100 × 465 =
80 × 465 ÷ 100 =
37,200 ÷ 100 =
372

Greetings from Brasil...
Note the graph of the function eˣ (or e⁻ˣ). We conclude that for any value of X, the result will be between 0 and +∞.\
So there is no value for X that the result of m.eˣ (or m.e⁻ˣ) is negative.
So you can answer:
For the equation of the statement of the question, with any value of X, we will always obtain a number greater than zero
S = {X | X∈ ℝ}(OBS: we'll never get zero. We can get very close, but never zero)

Answer:
8x-3
Step-by-step explanation:
The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.

Angle Measurements
Identify the relationship (complementary, linear pair/supplementary, or vertical) and find the
value of x in the image below.
(3x + 10)
47°
Answer:
X = 11
Complementary angles
Step-by-step explanation:
Complementary angles are when two angles add up to 90 degrees.
3x + 10 + 47 = 90
3x + 10 = 43
3x = 33
x = 11

The perimeter of a chalkboard is 16 feet. The area is 15 square feet. What are the dimensions of the board
Answer:
5 by 3
Explanation:
15 = 5 x 3
16 = 5 + 5 + 3 + 3
The dimensions of the board is either 5 by 3 square inches or 3 by 5 square inches.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
here,
let the length of the board be x, and width be w,
The perimeter of the rectangle board = 16
2 (l + w) = 16
l + w = 8
l = 8 - w
Now,
area of the board = 15
l × w = 15
(8 - w)w = 15
8w - w² = 15
w² -8w + 15 =0
(w - 3)(w -5) = 0
So,
w = 3 or 5
Now,
Lengths = 8 - 3 or 8 - 5
= 5 or 3
Thus, the dimension of the board either 5 by 3 square inches or 3 by 5 square inches.

Decide whether the given ordered pair is a solution of the system.
x+y=5
X-y= 3
; (4,1)
Is the given ordered pair a solution to the given system?
A. Yes, because (4,1) makes both equations true.
B. No, because (4,1) makes neither equation true.
C. No, because (4,1) only makes the equation x + y = 5 true.
D. No, because (4,1) only makes the equation x-y = 3 true.
Answer:
A. it is true for both equations
Step-by-step explanation:
x = 4 and y = 1
sub these values into the equations
4 + 1 = 5
4 - 1 = 3

1) 4x + 3p + 3p + 6x
10x + 6p
Step-by-step explanation:Hi there !
4x + 3p + 3p + 6x =
= (4x + 6x) + (3p + 3p)
= x(4 + 6) + p(3 + 3)
= x·10 + p·6
= 10x + 6p

5000 bricks of size 20cm × 12cm each are required to pave the path running outside a square field. Calculate the area of the path.
Step-by-step explanation:
20x12= 240cm^2 (the size of one brick)
If there are 5000 bricks then you multiply 240cm^2 by 5000
5000x240= 1,200,000cm^2
(it's a huge number so I'm not so sure about this)
