Answer:
Step-by-step explanation:
Sea x la cantidad de litros de la mezcla al 86%
x× 86% + 11 × 71% = (x + 11) × 77%

Freddy tiene $250 en billetes de diez dólares. ¿Cuántos billetes de diez dólares tiene Freddy? Le dio 6 billetes de diez dólares a su hermano. ¿Cuántos billetes de diez dólares le quedan?
Answer:
-Freddy tiene 25 billetes de diez dólares.
-A Freddy le quedan 19 billetes de diez dólares.
Step-by-step explanation:
Para encontrar la cantidad de billetes de diez dólares que tiene Freddy, tienes que dividir la cantidad total que tiene entre diez:
250/10=25
Esto significa que Freddy tiene 25 billetes de diez dólares.
Para saber cuantos billetes le quedan a Freddy, tienes que restar los 6 billetes que le dio a su hermano del total de billetes que tenía:
25-6=19
De acuerdo a esto, a Freddy le quedan 19 billetes de diez dólares.

Analyze the conditional statement below and complete the instructions that follow.
If m is the midpoint of AB, then M divides AB into two congruent segments.
Identify the inverse of the converse of the conditional statement.
O If M is not the midpoint of AB, then M does not divide AB into two congruent segments.
If M is the midpoint of AB, then M divides AB into two congruent segments.
If M divides AB into two congruent segments, then M is the midpoint of AB.
Olf M does not divide AB into two congruent segments, then M is not the midpoint of AB.
Answer:
D. If M does not divide AB into two congruent segments, then M is not the midpoint of AB.
Step-by-step explanation:
A conditional statement is one that include 'if'. Thus it is also referred to as an 'if' statement.
Given a conditional statement:
If M is the midpoint of AB, then M divides AB into two congruent segments.
The converse of the given statement is done by interchanging the two parts of it. So that we have:
If M divides AB into two congruent segments, then M is the midpoint of AB.
Then, the inverse can be obtained by getting the negative of both parts of the converse. Therefore, the inverse is:
If M does not divide AB into two congruent segments, then M is not the midpoint of AB.
The correct option is D.

Alice rode her bicycle the same number of miles every day for 17 days. She
rode a total of 68 miles during these 17 days. At this rate, how many miles did
Alice ride her bicycle in 1 day?
Answer: 4
Step-by-step explanation:
Alice ride her bicycle in 1 day for a distance of 4 miles.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given that,
Alice rode her bicycle the same number of miles every day for 17 days.
Let x be the number of miles that Alice rode for 1 day.
She rode x miles for 17 days.
Total number of miles that she rode in 17 days = 68 miles
So, we have,
17x = 68
Dividing both sides by 17,
x = 4
Hence the number of miles Alice rode in 1 day is 4 miles.

Why does sin54°≈0.809≈cos36° in a right triangle?
A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
B
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the adjacent leg and the hypotenuse and cos36° is the ratio of the opposite leg and the hypotenuse. In this triangle, the adjacent leg of 54° and the opposite leg of 36° are the same leg in the triangle.
C
54° and 36° are supplementary in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and adjacent leg of 36° are the same leg in the triangle.

Step-by-step explanation:
The answer explains itself.
The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are complementary (not supplementary).

The value of the expression 17[cos(315°) + isin(315°)] will be (17√2 / 2) – (17√2 / 2)i. Then the correct option is A.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The rectangular form of 17(cos(315°) + isin(315°)).
We know that the value of cos 315° and sin 315°.
[tex]\sin 315^o = \dfrac{-1}{\sqrt2}\\\cos 315^o = \dfrac{1}{\sqrt2}[/tex]
Then the value of the expression will be

To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32. Which answer is the best first step to solve the equation for C?
Answer: I think that the guy above is right just subtract 32.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The first step in solving the equation for C is
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
F - 32 = 95C
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
We have,
To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32.
Solve for C.
F = 95C + 32
Step 1:
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
F - 32 = 95C
Divide both sides by 95.
(F - 32)/95 = C
C = (F - 32) / 95
Thus,
The first step in solving the equation for C is
Subtract 32 on both sides.
F - 32 = 95C + 32 - 32
