The inequality is 2(3x - 5) ≤ (4x + 6) and the solution of the inequality is (-0, 8]
Let the number be x,
Twice the difference of three times a number and five = 2(3x - 5)
The sum of four times a number and six is (4x + 6)
2(3x - 5) ≤ (4x + 6)
6x - 10 ≤ 4x + 6
6x - 4x ≤ 6 + 10
2x ≤ 16
x ≤ 8
x can be any positive number less than or equal to 8.
Therefore, the inequality is 2(3x - 5) ≤ (4x + 6) and the solution of the inequality is (-0, 8]

The right angle, or 90°, is always one angle. The hypotenuse is the side with the 90° angle opposite.
If the side of DF = 7.7 cm then DE = 3.7 cm.
What is meant by right angle triangle?The right angle, or 90°, is always one angle. The hypotenuse is the side with the 90° angle opposite. The longest side is always the hypotenuse. The other two inner angles add up to 90 degrees.
A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a rectangled triangle. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Given: DF = 7.7 cm and ∠ E = 29°
Let the equation be
sin θ = P/h = DF / DE
substitute the values in the above equation, we get
⇒ sin 29° = 7.7 / DE
⇒ DE = 7.7 / 0.48 = 3.696 = 3.7 cm
Therefore, the correct answer is option a) 3.7 cm.

Answer:
87
Step-by-step explanation:
Answer:87
Step-by-step explanation:
what is the type of angle are <1 and <14??????????
1° and 14° are acute angles.
An acute angle is one that is less than 90°, or one that is between 0° and 90°.
The opposite of an acute angle is an obtuse angle. In other terms, an obtuse angle is one that is larger than 90° and less than 180°. It is the angle that is between 90° and 180°.
90° is the standard for a right angle. Any angle that is less than 90° is called acute, and any angle that is larger than 90° is called obtuse.
∠1 and ∠14 are less than 90° therefore, they are acute angles.

PLS ANSWER FAST!!! A triangle has coordinates R(2,−1),S(3,3), and T(4,6). The triangle is dilated by a scale factor of 1.5 with the origin as the center of dilation. What is the x-coordinate of R′ in the dilated triangle?
The x-coordinate of point R′ after dilation is 3
How to determine the x-coordinate of R′ after dilation?The given parameters are:
R(2,−1),S(3,3), and T(4,6).
The scale factor of dilation is given as
Scale factor = 1.5
Mathematically, this transformation can be represented as
(x, y) = 1.5(x, y)
When represented as a function, we have
Image = 1.5 * Point
For point R, we have
R = (2, -1)
Substitute the equation Point = (2, -1) in the equation Image = 1.5 * Point
So, we have the following equation
R' = 1.5 * (2, -1)
Evaluate the product
R' = (3, -1.5)
Remove the y-coordinate
R'x = 3
Hence, the image of the x cooridnates is 3

we have a coin which, with equal odds, is either weighted so that heads has .75 probability, or weighted so that heads has .25 probability. we flip the coin twice and observe two heads. what is the conditional probability that the coin is weighted toward heads with .75 probability?
The Conditional Probability that the coin is weighted towards heads is 0.25/0.75 . Conditional probability is the result of Bayes’ Theorem .
A coin is tossed twice . So, total outcomes are { HH , TH , HT, TT} that is 4 .
Probability= favourable outcomes / total outcomes
Probability of getting two heads = ¼ = 0.25
Favourable outcomes are { HH , HT, TH}
Probability of getting at least one head = ¾ = 0.75
Conditional probability is measure of the probability of an event occurring, given that another event has already occurred.
Formula , P(A|B) = P(A and B)/ P(B)
Here, p(A|B) is conditional probability of A given B
P(B) is probability of event B occur
P(A and B) is probability of both events A and B occur
We have to find conditional probability that coin is weighted towards heads and it is = Probability of getting both heads / probability of getting at least one head
= ¼ / ¾ = 0.25 / 0.75
Which is required result .

Then, your would solve the 1 1/4 - 3/4 and get 1/2.
You then have to multiply -8/27*1/2, which is -4/27.
Lastly, you divide by negative 4.
-4/27 divided by -4.
You have to flip it to multiply the reciprocal, and you get -4/27*-1/4.

Mrs. Doctor made a pot of hot chocolate in the teacher’s lounge. She wants to put 2/3 cup of hot chocolate into mugs to share with the other teachers. The pot holds 10 cups. How many mugs will Mrs. Doctor be able to fill?
Using the mathematical operation of division, Mrs. Doctor can fill 15 mugs using 10 cups.
What is the division operation?The division operation is one of the basic mathematical operations.
The division operation involves using the divisor to divide the dividend, which results in a quotient.
For instance, since the pot holds 10 cups and the distribution is 2/3 cups for each mug, we can divide 10 cups by 2/3 cups to get 15 mugs.
The quantity of hot chocolate for each mug = 2/3 cups
The total number of cups that the pot holds = 10 cups
The number of mugs that can be filled from 10 cups = 15 (10 ÷ 2/3)
Thus, we can divide 10 cups by 2/3 cups to get the number of mugs Mrs. Doctor can fill.

You have the following expression:
39 + (-20.4)
In order to simplify the previous expression, you first eliminate the parenthesis. To do that, you take into account that the sign before the parenthesis must multiply the sign inisde. In this case, you have a positive sign + before the parenthesis, and inside you have a minus -. When the parenthesis is eliminated, these signs are multiplied (here you use the multiplication rule for signs). Thus, you have that - x + = - (positive multiplied by negative is equal to negative). And the expression becomes:
39 + (-20.4)
= 39 - 20.4
= 18.6
Hence, the simplified expression is 18.6
