A. x + 0 = 0
B. x + x = 0
C. 0 - x = x
D. x + (-x) = 0

That is the answer because if you are x feet above sea level, to get back to sea level, which equals zero (0), you need to go down the same amount you went up (x), so you need to go down x feet (-x).

Sandy can jog 3 2/5 miles in 5/6 hour. Find her average speed in miles per hour.
Answers
(17/5 mi)/(5/6 hr) = 102/25 mi/hr
Answer:
[tex]4\frac{2}{25}[/tex] miles per hour
Step-by-step explanation:
Sandy can jog a distance [tex]3\frac{2}{5}[/tex] miles or [tex]\frac{17}{5}[/tex] in the duration = [tex]\frac{5}{6}[/tex] hours
Since speed = [tex]\frac{distance}{time}[/tex]
We plug in the values of distance and time in the formula of speed.
Speed = [tex]\frac{\frac{17}{5}}{\frac{5}{6}}[/tex]
= [tex]\frac{17}{5}[/tex] × [tex]\frac{6}{5}[/tex]
= [tex]\frac{102}{25}[/tex]
= [tex]4\frac{2}{25}[/tex] miles per hour
Her average speed is [tex]4\frac{2}{25}[/tex] miles per hour.

If ∠ABD = 56, find ∠DBC.
a) 124
b) 56
c) 44
d) 34
Answers
The measure of ∠DBC is determined based on the concept that two angles forming a straight line are supplementary, which means their measures add up to 180 degrees. Thus, ∠DBC = 180 - ∠ABD = 180 - 56 = 124 degrees.
Explanation:The subject of the given question pertains to Mathematics, specifically geometrical interpretation of angles. We have a situation where the measure of ∠ABD is provided as 56 degrees and we are asked to determine the measure of ∠DBC. This is a well-known scenario in geometry where one angle is given and the other is to be determined.
Important observation here is that ∠ABD and ∠DBC are on a straight line, thus they are supplementary angles. We know that the sum of supplementary angles is 180 degrees. Hence, the measure of ∠DBC will be: ∠DBC = 180 - ∠ABD = 180 - 56 = 124 degrees. So, the correct answer is (a) 124.

A hot air balloon leaves the ground and ascends at a rate of 6 feet per second for 3 minutes. Then it descends at a rate of 3 feet per second for 2 minutes. Finally, it ascends at a rate of 4 feet per second for 5 minutes. How far above the ground is the balloon now?
Answers
State 1:
A hot air balloon leaves the ground and ascends at a rate of 6 feet per second for 3 minutes.
1 minute = 60 seconds
3 minutes = 180 seconds
If it's rate of is 6 feet per second
Last of 3 minutes, it will ascend (180 seconds x 6 feet) 1080 feet.seconds. That is we can write +1080 feet.seconds
State 2:
Then it descends at a rate of 3 feet per second for 2 minutes.
2 minutes = 120 seconds
If it's rate of is 3 feet per second
Last of 3 minutes, it will descent (120 seconds x 3 feet) 360 feet.seconds that is we can write -360 feet.seconds
State 3:
It ascends at a rate of 4 feet per second for 5 minutes.
5 minutes = 300 seconds
If it's rate of is 4 feet per second
Last of 5 minutes, it will ascent (300 seconds x 4 feet) 1200 feet.seconds that is we can write +1200 feet.seconds
Last State:
+1080 feet.seconds ascent (1)
-360 feet.seconds descent (2)
+1200 feet.seconds ascent (3)
Conclusion:
(+1080 feet.seconds) + (-360 feet.seconds) + (+1200 feet.seconds) = +1920 feet.seconds
Answer: +1920 feet.seconds
A triangle has the following angle measures: 125°, 15°, and 40°. Which of the following statements best describes its drawing?
A)It is impossible to construct a triangle with these angle measures.
B)There is one possible triangle with these angle measures.
c)There are many possible triangles with these angle measures.
D)There are many possible similar triangles with these angle measures.
Answers
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Measures of angles are as follows:
125°, 15°, 40°
As we know the sum of all angles in a triangle is supplementary i.e. 180°.
∠A+∠B+∠C=180°
125°+15°+40°=180°
Therefore, it is satisfying the angle sum property.
So, it can form a triangle.
Now, we will check for uniqueness.
As similar triangles need two angles to be equal by AA criteria , their sides can vary with two equal angles.
Hence, there is possibility to have many possible similar triangles with angle measures.
Therefore, Option 'D' is correct.

The required difference in the temperature between the cities of Houston and Indianapolis is 31°F.
Given that,
Wednesday's low temperature in Indianapolis with 25 degrees Fahrenheit the same day in Houston's low temperature was above 56°F at least how many degrees warmer the low temperature in Houston than the low in Indianapolis is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
The temperature of Indianapolis is 25°F.
The temperature of Houston is 56°F.
The difference in the temperature = 56°F - 25°F = 31°F

Twenty-one out of 70 customers at the restaurant ordered dessert. What percentage of the customers did not order dessert?
Answers
To find your answer you must subtract first:
70 - 21 = 49
Now, how much percent is 49 of 70?
49/70 = 0.7000
0.7000 * 100 = 70.00%
49 is 70% of 70.
I really hope this helped you! :)
To check your answer: (70 × 70.00)/100 = 49
70 - 21 = 49
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
[tex] \frac{49}{70} [/tex] = [tex] \frac{x}{100} [/tex]
Cross multiply.
70x = 4,900
Now, all you would need to do is isolate the x. To do this, you would divide both sides by 70.
x = 70
x = 70%
So, 70% of the customers ordered dessert.

-3 times what equals 9
Answers
x = 9 / (-3)
x = -3 <== so -3 * -3 = 9
The value to fill in the blank is -3.
So, -3 x -3 = 9.
We have,
To solve the equation -3 x __ = 9, we need to find the value to fill in the blank that makes the equation true.
Let's denote the value we need to find as "x".
When we multiply -3 by "x", it means we are adding -3 to itself "x" times.
So, the equation becomes -3 times "x" equals 9:
-3x = 9.
To solve for "x", we can divide both sides of the equation by -3:
-3x / -3 = 9 / -3
This simplifies to:
x = -3
Therefore,
The value to fill in the blank is -3. So, -3 x -3 = 9.

Explain how to solve rate of wind and rate of current problems
Answers
Final answer:
To solve rate of wind and current problems, analyze the given velocities, represent them as vectors, perform vector addition, and apply trigonometry to find the effective velocity or required direction. This method helps in determining the true path of a vehicle influenced by wind or current.
Explanation:
To solve rate of wind and rate of current problems, it is essential to understand vectors and relative motion. Here is a step-by-step approach to solving these problems:
Analyze the question to understand what is being asked, including the direction and magnitude of both the wind/current and the vehicle (aircraft, boat, etc.).Represent the given velocities as vectors. The wind or current velocity should be added to the vehicle’s velocity to determine the resulting path.Apply the vector addition concept to calculate the effective velocity of the vehicle relative to the Earth. This might include using trigonometric functions to resolve vectors into components.Once the effective velocity is known, use it to solve for other quantities like travel time, distance, or the required heading to reach a certain destination.For example, if an aircraft flies with a wind velocity of 200 km/hr blowing from the south and its relative velocity with respect to wind is 1000 km/hr, the direction in which the aircraft should fly to reach a north-eastern destination can be calculated using vector addition and trigonometry.

Give one combination of two factors whose product is 0.24, if one of the factors is a whole number greater than 1.
Answers
Answer:
Product of two factors =0.24
It is given that one of the factors is greater than 1.
Because 0.24 when reduced in fraction form , numerator will be divisible by 1,2,3,4,6,8,12,and 24.
So, you can choose from any one of them.
So, let one factor= 2
So, other will be
= 0.24 ÷ 2
=0.12
One Combination is=(2, 0.12)
The combination of two factors whose product is 0.24 is 24 x 0.01
The product = 0.24
Convert 0.24 from decimal to fraction
0.24 = 24/100
24/100 can be rewritten as 24 x 1/100
Since 24 is a whole number greater than 1, find the decimal equivalent of 1/100
1/100 = 0.01
0.24 = 24 x 0.01
Therefore, one of the combinations of factors of 0.24 the where one of them is a whole number greater than 1 is 24 x 0.01.
