Answer:
7.7 %
Step-by-step explanation:
352-325
=27
27/352 x 100/1
7.670
=7.7%
Answer: 7.7%
Step-by-step explanation:
1. 352 - 325 = 27. This is how many students left.
2. x/100 = 27/352 is the equation.
3. Solve for x: 2700/352 = x = 7.6704
This rounded to the nearest tenth is 7.7%

What is the equation of the line that passes through the point (-5,5) and has a
slope of -1?
Answer:
y = - x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 1 , then
y = - x + c ← is the partial equation
To find c substitute (- 5, 5 ) into the partial equation
5 = 5 + c ⇒ c = 5 - 5 = 0
y = - x ← equation of line
Robin read 63 books last year. She read 9 more books than
Trisha. The equation b + 9 = 63 gives the number of books b
that Trisha read last year. Which is the solution of the
equation?
Answer: 54
Step-by-step explanation:
63-9 you can't take 9 away from 3 so you must borrow, the 6 becomes a 5 and the 3 becomes 13. 13-9 is 4, bring the 5 down and you have 54.

PLS HELP I'LL GIVE BRAINLYIST
Answer:

8 + 4 = 12 x 7 = 84m
Explain why the product of a non-0 rational number and an irrational number is irrational?
Answer:
An irrational number is a number that can not be written as the quotient of two integer numbers.
Then if we have:
A = a rational number
B = a irrational number.
Then we can write:
A = x/y
Then the product of A and B can be written as:
A*B = (x/y)*B
Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.
(x/y)*B = (m/n)
If we isolate B, we get:
B = (m/n)*(y/x)
We can rewrite this as:
B = (m*y)/(n*x)
Where m, n, y, and x are integer numbers, then:
m*y is an integer
n*x is an integer.
Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.
Then the product of an irrational number and a rational number different than zero is always an irrational number.
We need to add the fact that the rational number is different than zero because if:
B is an irrational number
And we multiply it by zero, we get:
B*0 = 0
Then the product of an irrational number and zero is zero, which is a rational number.

Answer:
She has to buy 48 inches of ribbon
Step-by-step explanation:
We know that the pillow is a square with an area of 144. This means that all the side lengths must be the same. If we take the square root of 144 we get 12 which is the length of one side of the square. Because there are four sides to a square, we multiply this by 4. So 12 x 4 = 48 inches of ribbon.

on a piece of paper graph y ≤ -2x . then determine which answer choice matches the graph you drew. Which of the following is correct?.
Answer:
The correct answer is D
Step-by-step explanation:
The graph of inequality y ≤ -2x is option D .
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
According to the question
y ≤ -2x
The graph of inequality
at x = -2
y≤ 4
at x = 3
y ≤ -2*3
y ≤ -6
Hence, the graph of inequality y ≤ -2x is option D .

find the y-coordinate of the y-intercept of the polynomial function defined below f(x)=2x(x^2+3)
Answer:
y-intercept is (0,0). Mark brainliest?
Answer:
Step-by-step explanation:
2x([tex]x^{2}[/tex] + 3)
when x = 0 then we have a y intercept
2[tex]x^{3}[/tex] +6x
so b/c both terms have an x in them
we know the only time this function hits the y intercept is when y is zero
got it?
answer y = 0
