Answer: 35 ft
Step-by-step explanation:
Given
Vertical height from the eyes of the person to the top of the flag is \(X-5\)
Horizontal distance is \(30\ ft\)
The angle of elevation is \(45^{\circ}\)
From the figure, we can write
\(\Rightarrow \tan 45^{\circ}=\dfrac{X-5}{30}\\\Rightarrow 1=\dfrac{X-5}{30}\\\\\Rightarrow X-5=30\\\\\Rightarrow X=35\ ft\)

Maria bought g gallons of gas, spending a total of $43.95. Each gallon of gas costs $2.93.Find the number of gallons
Answers
the number of gallons bought is 15 gallons
Explanation:Number of gallons bought = g
Total cost of the g gallons = $43.95
The cost of one gallon = $2.93
Total cost of g gallons = Number of gallons bought × The cost of one gallon
$43.95 = g × $2.93
43.95 = 2.93g
Divide both sides by 2.93:
43.95/2.93 = 2.93g/2.93
15 = g
Hence, the number of gallons bought is 15 gallons
I need help with Systems of 2 equations Word Problems. Could some one help?
Answers
Let x be the number of children and let y be the number of adults.
We know that the total number of attendants was 147, then:
\(x+y=147\)We also know that each child ticket cost $4 and for each adult cost $12, and the total amount collected were $1156. Then we have:
\(4x+12y=1156\)Hence we have the system:
\(\begin{gathered} x+y=147 \\ 4x+12y=1156 \end{gathered}\)Now we have to solve the system. To do that we solve the first equation for y:
\(y=147-x\)and we plug this value into the second equation and solve for x:
\(\begin{gathered} 4x+12(147-x)=1156 \\ 4x+1764-12x=1156 \\ -8x=1156-1764 \\ -8x=-608 \\ x=\frac{-608}{-8} \\ x=76 \end{gathered}\)Now that we have the value we can find the value of y, then:
\(\begin{gathered} y=147-76 \\ y=71 \end{gathered}\)Therefore there were 76 children and 71 adults.

Answer:
24°
Step-by-step explanation:
because a right angle measures 90°. so 90° minus 64° is 24°.
Answer:
26°
Step-by-step explanation:
The sum of all degrees in a triangle is 180°.
You already have the value of two angles, 90° and 64°.

Answer:
Based on the diagram, we can see that the triangle formed by the line segment with length 8 and the two dashed line segments is a right triangle with a 45° angle. This means that the other two angles of the triangle are also 45° each.
Using the properties of 45°-45°-90° triangles, we know that the length of the hypotenuse is equal to the length of either leg times the square root of 2. Therefore, we have:
x = 8 / sqrt(2) = 8 * sqrt(2) / 2 = 4 * sqrt(2)
So the value of x is option B: 8√2 / 2 or simplified, 4√2.
What are the solutions to the equation 0=|3x+3|+3
Answers
Therefore, the solutions to the equation 0 = |3x + 3| + 3 are x = -2 and x = 0.
To solve the equation 0 = |3x + 3| + 3, we need to eliminate the absolute value. Remember that the absolute value of a number is always non-negative.
First, let's isolate the absolute value term on one side of the equation:
|3x + 3| = -3
Since the absolute value cannot be negative, there are no solutions to the equation as it stands. However, if we modify the equation to make the right side positive, we can find a solution.
To eliminate the absolute value, we can rewrite the equation as two separate equations, considering both the positive and negative cases:
3x + 3 = -3
-(3x + 3) = -3
Solving equation 1:
3x + 3 = -3
3x = -6
x = -2
Solving equation 2:
-(3x + 3) = -3
-3x - 3 = -3
-3x = 0
x = 0

What is the reflexive property of congruence?
According to the reflexive feature of congruence, the geometric quantity under consideration—be it an angle, a line segment, a form, etc.—is congruent to itself.
The third step's key concept in this instance is the "Reflexive Property of Congruence."
The fourth phase comes to the conclusion that the ΔABC~ΔBDC criteria for similarity are met.
Since it was established in the second stage that ∠ABC≅∠BDC
Therefore, in order for the fourth step to apply angle-angle similarity, which requires the angles of two considered triangles to be congruent, we must demonstrate another angle pair of triangles ΔABC and ΔBDC being congruent in the third step.
Internal angle C is the common angle in the triangles ABC and BDC.
As a result, it is consistent with itself due to its reflexive characteristic.
We obtain the following notation for internal angle C from triangle ABC:
Angle ACB and BCA(both will work)
Triangle BDC gives us the following notation for internal angle C:
Angle DCB and BCD(Both will function.)
They fit together. The second choice takes angle C into account, so:
∠BCA≅∠DCB (second option) is the missing statement.

The experimental probability that more than 10 spins are needed to land on each letter at least once is 75%
How to explain the probabilityExperimental probability is a type of probability that is based on actual observations or experiments.
In experimental probability, the probability of an event occurring is calculated by conducting experiments and observing the outcomes. The probability of the event is then calculated by dividing the number of times the event occurred by the total number of trials or experiments.
In this case, experimental probability = number of times the event occurred / total number of trials
Experimental probability = 0.1 + 0.35 + 0.3 / 1
= 0.75 / 1

7. Kelly developed a formula for using a computer to find for a specific quote within a large set of articles.
The following function gives the length of the search, in seconds, over a set of n articles.

Use correct units to explain the meaning of the answer.
Answers
instantaneous rate of change of the search length 0.1667 seconds per
How to find the instantaneous rate of change?We need to take the derivative of the function S(n) with respect to n and evaluate it at n=12 in order to determine the instantaneous rate of change of the search length for a set of 12 articles.
Taking the derivative of S(n) with respect to n using the chain rule, we get:
S'(n) = 1.6 * (1/(0.8n)) * 0.8 = 2/n
Evaluating this expression at n=12, we get:
S'(12) = 2/12 = 0.1667 seconds per article
This indicates that the search time will increase by approximately 0.1667 seconds per article if the set contains 12 articles by one unit. Alternately, the search time per article will decrease by approximately 0.1667 seconds if the set's number of articles decreases by one unit from 12.
Therefore, the units for the instantaneous rate of change are "seconds per article", indicating the change in search time for each additional or fewer article in the set.
