Answer:
Last year were 161 floats, that is, 34 more than this year.Step-by-step explanation:
Givens
There are 127 floats this year.That represents 34 fewer floats than last year.The second given statement expresses that this year there are 34 LESS floats. So, to know how many floats were there last year, we just need to sum
[tex]127+34=161[/tex]
Therefore, last year were 161 floats, that is, 34 more than this year.

How can I tell if they are none transversal?
A non-transversal line in geometry is a line that does not intersect two or more lines at distinct points. Similarly, in geology, folds with a horizontal axial line, called non-plunging folds, can be analogous to non-transversal lines as they don't intersect with another structure at a distinct point.
Explanation:In mathematics, specifcally in geometry, transversal is a line that passes through two lines in the same plane at two distinct points. If a line does not intersect two or more lines at distinct points, it can be considered as a non-transversal line.
According to the information provided, in the context of folds in geology, the axial line becomes a key concept. The axial line refers to an imaginary line drawn along the crest of a fold. If the axial line is horizontal, the fold is referred to as a non-plunging fold and it could be analogous to a non-transversal line in geometry, as it doesn't intersect with another structure at a distinct point.
However, if the axial line is tilted (plunging), it might be considered as a transversal in the sense that it 'intersects' the horizontal plane at a distinct angle. Similarly, if a line in geometry is tilted and intersects two or more lines at distinct points, it is a transversal line.

Find the greatest possible value of the product xy, given that x and y are both positive and x + 2y = 30
Answer: The maximum value of the product x*y is 112.5
Step-by-step explanation:
We have that x + 2y = 30
so we can isolate one of the variables and get:
x = 30 - 2y
now, the product of x*y can be written as:
x*y = (30 - 2y)*y = 30y - 2y^2
now, we want to find the maximum of 30y - 2y^2
because the leading coeficient is negative (-2), we know that the hands of the quadratic function will go downwards, so the zero of the derivate of this quadratic equation will give us the value where the equation has a maximum:
f(y) = -2*y^2 + 30*y
f'(y) = -4*y + 30 = 0
y = -30/4 = 7.5
So the maximum value is:
f(7.5) = -2*7.5^2 + 30*7.5 = 112.5
Determine the exponential function that satisfies the given conditions:
The initial mass is 1.4g and it is halving every 4 days.
To determine the exponential function, use the general form of an exponential function and substitute the given values. The equation is y = 1.4 * (1/2)^(x/4).
Explanation:An exponential function represents exponential growth or decay. In this case, the given information states that the initial mass is 1.4g, and it is halving every 4 days. We can use the general form of an exponential function, y = ab^x, where a is the initial value, b is the growth/decay factor, and x is the time in days.
Since the mass is halving every 4 days, the decay factor is 1/2, since the mass is halving. The equation becomes y = 1.4 * (1/2)^(x/4).
This equation represents the exponential function that satisfies the given conditions.

20/4 = 5
40/8 = 5
60/12 = 5
80/16 = 5
Answer is 5
Answer:
Option D 5
Step-by-step explanation:
Mike and Julie surveyed students to determine how many had a grade of A in math as given in the table.
We have to find the proportionality constant of the ratio of students surveyed to the number of A grades.
Since proportionality constant = [tex]\frac{\text{Students Surveyed}}{\text{number of A grades}}[/tex]
=[tex]\frac{20}{4}=5[/tex]
Similarly we can get the constant form other data which is equal to 5.
Therefore, Option D. 5 is the correct option.
A conjecture and the paragraph proof used to prove the conjecture are shown.

It is given that ∠1≅ ∠4 . By the vertical angle theorem, [blank] ≅∠1 . Therefore, ∠2≅∠4 by the substitution property. By the [blank] , ∠4≅∠3 . So, ∠2≅[blank] by the [blank]
choices:
verticle angle theorim, transitive property of congruence, ∠4, ∠3, ∠2, ∠1
Answer:
∠2; vertical angle theorem; ∠3; transitive property of congruence
Step-by-step explanation:
∠2 and ∠1 are opposite angles that share only a vertex. This is the definition of vertical angles, and by the vertical angle theorem they are congruent.
Substituting ∠2 for ∠1 in our "given" statement, we now know that ∠2≅∠4.
∠4 and ∠3 are opposite angles that share a vertex. This makes them vertical angles, and the vertical angle theorem states that they are congruent.
The transitive property, algebraically, states "if a=b and b=c, then a=c." Applied to this proof, it states "if ∠2≅∠4, and ∠4≅∠3, then ∠2≅∠3."
The required solution for the blacks,
Blank 1 = ∠2;
Blank 2 = vertical angle theorem;
Blank 3 = ∠3; the transitive property of congruence.
It is given that
∠1≅ ∠4 . By the vertical angle theorem, [blank] ≅∠1 . Therefore, ∠2≅∠4 by the substitution property. By the [blank] , ∠4≅∠3 . So, ∠2≅[blank] by the [blank].
To determine the missing statement at the place of blanks in the statement.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Since
Black 1
∠2≅∠4
and ∠1≅ ∠4
So ∠2 ≅ ∠1
Blank 2
∠2≅∠4 are equal by the vertical angle theorem.
Blank 3
∠4≅∠3
∠3 ≅∠1
So,
∠2 ≅ ∠1 ; ∠2≅∠3 and ∠4≅∠3 it is transitive property of congruence.
Thus, the required solution for the blacks,
Blank 1 = ∠2;
Blank 2 = vertical angle theorem;
Blank 3 = ∠3; the transitive property of congruence.

What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given a equation 12/25 x 5/18 we need to simplify this
Using PEMDAS
12/25 * 5/ 18
=> (12 * 5)/ 25 *18
=> 2 / (5 * 3)
=> 2/15
Therefore, Value of 12/25 x 5/18 in the simplest form is 2/15.

Cost of 1 roll = $1
The baker needs to sell both items and it should be worth $35.
To find the linear equation, Suppose, the baker sells “b” loaves of bread and “r” rolls.
Then the total cost of the sales has to be $35.
