Answer:600 students
Step-by-step explanation:
Answer:
There are 600 students participating. The operation you have to carry out is 800 × .75 = 600.
Or you can simply divide 800÷4= 200. 3/4=200×3. The percentage of students is 3/4 that would be 600 students participating.
Which function has a greater constant rate of change explain. Function A y=10x-3 or function B x 1 2 3 4 5 and y are 20 15 10 5 0
Answer:
The function B has greater constant
Step-by-step explanation:
[tex]m(b) = \frac{20 - 15}{1 - 2} = - 5 \\ y = - 5x + c \\ when \: y = 20 \: \: \: \: \: and \: x = 1 \\ 20 = - 5 \times 1 = c \\ c = 25[/tex]
if x-y=9,x²+y²=27,then xy=?
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy

If anybody answers these questions I will get them brainliest and if somebody else verifies that it is the correct answer I can give you a thanks.
Part (a)
Answer: x^3 + 12x^2 + 47x + 60--------------------------
Work Shown:
Let's say we have
L = length = x+5W = width = x+4H = height = x+3To find the volume of the block, we multiply the length width and height.
So,
volume = (length)*(width)*(height)
V = L*W*H
V = LW*(x+3) .... replace H with (x+3)
V = LW*x + LW*3 .... distribute
V = Lx*(W) + 3L*(W)
V = Lx(x+4) + 3L(x+4) .... replace W with x+4
V = Lx^2 + 4Lx + 3Lx + 12L .... distribute
V = Lx^2 + 7Lx + 12L
V = x^2*(L) + 7x*(L) + 12*(L)
V = x^2*(x+5) + 7x*(x+5) + 12*(x+5) .... replace L with x+5
V = x^3 + 5x^2 + 7x^2 + 35x + 12x + 60 .... distribute
V = x^3 + 12x^2 + 47x + 60
x^3 + 12x^2 + 47x + 60 is the polynomial in standard form that represents the volume of the block.
=======================================================
Part (b)
Answer: 336 cubic feet--------------------------
Work Shown:
We can plug x = 3 into the polynomial we found
V = x^3 + 12x^2 + 47x + 60
V = (3)^3 + 12(3)^2 + 47(3) + 60
V = 27 + 12(9) + 47(3) + 60
V = 27 + 108 + 141 + 60
V = 336
Or we could find the volume like this
V = L*W*H
V = (x+5)*(x+4)*(x+3)
V = (3+5)*(3+4)*(3+3)
V = (8)*(7)*(6)
V = 336
Either way, we get the same volume of 336 cubic feet.

The semi-circle has a diameter of 8. What is the perimeter of the semi-circle?
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
Answer:
Approx. 20.566 units
Step-by-step explanation:
Find the circumference of the whole circle first by doing:
C = 2πr
r = 4 (8 divided by 2)
C ≈ 25.133
Then divide that by two because a semi-circle is half a circle:
12.566
Then add 8 (diameter) to that number for the open side.
Hope this helps :)

Given the equation 4(3n-7) = -19, what is the first step you could use to solve for n?
Answer:
3/4
Step-by-step explanation:
4(3n-7)=-19
3n-7=-19/4
3n=-19/4+7
3n=-19/4+28/4
3n=9/4
n=(9/4)/3
n=(9/4)(1/3)
n=9/12
simplify
n=3/4
Answer:
3/4
You would have to divide both sides by 4
Step-by-step explanation:
[tex]\frac{4(3n-7)}{4} =\frac{-19}{4}[/tex] ( divide both sides by 4 )
[tex]3n-7= -\frac{19}{4}[/tex] ( simplify )
[tex]3n-7+7=-\frac{19}{4} +7[/tex] ( add 7 to both sides )
[tex]3n=\frac{9}{4}[/tex] ( simplify )
[tex]\frac{3n}{3} =\frac{\frac{9}{4} }{3}[/tex] ( divide both sides by 3 )
[tex]n=\frac{3}{4}[/tex]

[tex]m= 14 \sqrt 2, \: n = 14[/tex]
Step-by-step explanation:
Hope it helps you in your learning process.
Given is a 45°-45°-90° triangle.
Measure of sides n and 14 are opposite to 45° degree angles.
Therefore, they are equal.
So, n = 14

HEEEEEEELPPPPP? What is the equation of the line in y=mx+b format?
Answer:
y = 2x+2
Step-by-step explanation:
Answer:
y = 2x + 2Step-by-step explanation:
Find the y-intercept first, then, from that point, go tide over run to find your slope. This line has a positive slope, so count up two and over one (2/1). After that, input what data you've collected into your equation (y = mx + b) and you'll have your answer.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Remark
This is a Pythagorean Problem
Formula
a^2 + b^2 = c^2
a = 5
b = ?
c = 9
Solution
5^2 + b^2 = 9^2 Expand the givens
25 + b^2 = 81 Subtract 25 from both sides
25-25+b^2 = 81- 25
b^2 = 56
√b^2 = √56
b = √8*7
b = √2*2*2*7
b = 2 √2*7
b = 2 √14

Which of the following is a pair of events which are dependent on one another?
a. observing rainfall in two different cities
b. drawing a pair of cards from a deck
c. putting on a pair of pants and a shirt without looking at them
d. rolling two dice with the same number of sides
Answer:
I think it's B
Step-by-step explanation:
because you won't draw the same card twice because you took that card out of the running
hope this helps sorry if I'm wrong
Putting on a pair of pants and a shirt without looking at them are pair of events which are dependent on one another
What is Probability?Probability is a branch of mathematics which deals with the occurrence of a random event.
Drawing a certain card from a deck probability depends on whether or not another card has been drawn previously, as it changes the number of cards remaining in the deck and the likelihood of drawing a certain card.
Drawing a pair of cards from a deck is the pair of events which are dependent on one another.
Hence, putting on a pair of pants and a shirt without looking at them are pair of events which are dependent on one another
