At occer practice for every 5 minute that bob run he pend 20 minute practicing dribbling if bob keep the ratio and he pend 36 mintue practicing dribbling how many minute doe he pend running
Bob spends 9 minutes running for every 36 minutes that he spends practicing dribbling.
What is ratio ?
A ratio is a mathematical comparison of two or more values or quantities. It is a way of expressing the relationship between different amounts or measurements.
The ratio of running to dribbling is 5 minutes of running to 20 minutes of dribbling. We can use this ratio to find out how many minutes Bob spends running if he spends 36 minutes practicing dribbling.
First, we can set up a proportion with the known ratio and the unknown value ,
5/20 = x/36
To find x we can cross-multiply to get ,
20x = 180
then divide both sides by 20 ,
x = 9
So, Bob spends 9 minutes running for every 36 minutes that he spends practicing dribbling.

What is the solution to an equation?
In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.
− 6(hx + 2) = 3(x − 3) + 2(x + 2) +13x
-6hx-12=3x-9+2x+4+13x
=> -6hx-12= 18x-5
=> -6hx = 18x-5 +12
=> -6hx = 18x+7
=> h = ( 18x+7 )/( -6x)
The system has no solution when h is not equal to ( 18x+7 )/( -6x)

How is the Declaration of Independence a reflection of the colonist’s motivations?
Answer: The Declaration of Independence, adopted by the Continental Congress on July 4, 1776, is a reflection of the colonists' motivations in several ways. Firstly, the Declaration states that the colonists believed that all men are created equal and have the right to life, liberty, and the pursuit of happiness. This reflects the colonists' belief in the Enlightenment principles of natural rights and individual liberty, which were influential in shaping their motivations for seeking independence from British rule.
Secondly, the Declaration cites a long list of grievances against King George III, accusing him of violating the colonists' rights and abusing his power. This reflects the colonists' growing frustration and anger towards British rule, which had been building for many years prior to the drafting of the Declaration.
Thirdly, the Declaration states that the colonists had attempted to resolve their differences with the British government through peaceful means, but that these efforts had been unsuccessful. This reflects the colonists' desire for a peaceful resolution to their issues, but their willingness to fight for their rights if necessary.
In summary, the Declaration of Independence reflects the colonists' belief in natural rights and individual liberty, their growing frustration and anger towards British rule, and their desire for a peaceful resolution to their issues but their willingness to fight for their rights if necessary.

last year, Reuben biked 496 miles. This year, he biked m miles. Using m, write an expression for the total number of miles he biked.
The total number of miles Reuben biked last year and this year is the sum of the miles he biked last year and this year.
You can represent the total number of miles he biked as:
Total miles = 496 + m
Where 496 is the number of miles biked last year and m represents the number of miles biked this year.
So the expression for the total number of miles he biked is 496 + m
What is the distance between points 2 3 and 5 7?.
The distance between two points (2, 3) and (5, 7) is 5 units.
Therefore the answer is 5.
To find the distance between the points (2, 3) and (5, 7), we can use the distance formula:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
where (x₁, y₁) = (2, 3) and (x₂, y₂) = (5, 7)
Substituting the coordinates of the two points into the formula:
d = √((5 - 2)² + (7 - 3)²)
d = √((3)² + (4)²)
d = √(9 + 16)
d = √(25)
d = 5
So the distance between the points (2, 3) as well as (5, 7) will be 5 units by solving the above expression.

Answer:
x = 79
Step-by-step explanation:
Since PQ and RS are most likely parallel lines, we can consider the orange angles (image provided below) to be similar due to them being alternate interior angles.
Now that we know that one angle of the triangle given (orange) is 46 degrees, we can solve for the other angle of the triangle. A triangle adds up to 180 degrees, so we can find the missing angle by subtracting 180 from the given angles: 180-33-46 = 101 (marked in red).
With the red angle, we can find x by subtracting 180 from 101. Why you may ask? Because RS is parallel to PQ, so the degree will be 180. Therefore, the missing angle, x, will be 79.

Answer:
x = 5
Step-by-step explanation:
Angles on a straight line add up to 180, so add up the angles and equate to 180:
9x + 85 + 10x = 180
Now we can solve for x by simplifying further:
19x + 85 = 180
Subtract 85 on both sides:
19x + 85 - 85 = 180 - 85
19x = 95
Divide 19 on both sides which cancels out the 19 on the left:
x = 95/19 = 5

Is 360 a full turn?.
Yes 360 degrees is full turn calling it a full rotation.
A degree is the name given to the mathematical unit of measurement for an angle. A protractor is a device used to determine the degree of an angle. Angles can be measured at different angles with different degrees, such as 30°, 45°, 60°, and so on. A complete circle rotates at 360°.
Each of the 360 equal segments that make up a rotation is referred to as a degree. We use a circle ° to represent a degree. 180°, for instance, denotes 180 degrees. An angle in degrees is an angle whose measure is expressed in degrees.
A 360 degree is also called as a Complete angle because it complete the whole round making the 180 degree angle twice giving us 360 degree.
A 360 when written as radian can be given by 2π ( where π= 180 degree)

There are 364 solutions to the given inequality: x1 + x2 + x3 <= 11.
To get the solution of the inequality x1 + x2 + x3 <= 11, we first need to include an additional variable in the inequation to write in as an equation.
Therefore, let the additional variable be x4.
Thus, equation is x1 + x2 + x3 + x4 = 11
The number of solutions of an equation can be calculated by the formula,

CB = 4√22/sin 90 × sin 45
CB = 4√11
or
CB = √(4√22)²-(4√11)²
= 4√11
Answer:
CB = AC = 4√11
Step-by-step explanation:
We know that the sum of the angles of a triangle is 180°. If angle A = 45° and C = 90°, then angle B = 180° - 90° - 45° = 45°. This shows us that the triangle is isosceles and the leg AC is equal to the leg CB.
Consequently: CB = AC = 4√11
If we didn't know the length of AC, then it can be calculated from the hypotenuse:
AC² + CB² = AB²
2 * CB² = (4√22)²
CB² = (4√22)² / 2
CB² = 16 * 22 / 2
CB = √(16 * 11)
CB = 4√11

Amelia cut a 168 inch long ribbon into 6 equal part. Patrick cut a 14 foot long ribbon into 7 equal piece
Amelia cut a 168 inch long ribbon into 6 equal part. Patrick cut a 14 foot long ribbon into 7 equal piece.
Amelia's ribbon pieces were 28 inches long each. Patrick's ribbon pieces were 2 feet long each.
Amelia's ribbon:
To calculate how long each piece of ribbon is, we need to divide 168 inches (the total length of the ribbon) by 6 (the number of pieces).
168 ÷ 6 = 28
Therefore, Amelia's ribbon pieces were 28 inches long each.
Patrick's ribbon:
To calculate how long each piece of ribbon is, we need to divide 14 feet (the total length of the ribbon) by 7 (the number of pieces).

are the inhabitants of a certain village on the Nigerian border speaker the French or English if 64% speak French and 58% speak English what percentage speak
both languages? Two set problems
Answer: We can use the formulas for conditional probability to calculate the percentage of people in the village who speak both French and English.
P(French and English) = P(French) x P(English|French)
We know that P(French) = 64% and P(English|French) is the probability of someone speaking English given that they already speak French, which is 58%. So we can plug these values into the formula:
P(French and English) = 64% x 58% = 37.12%
Therefore, 37.12% of the inhabitants of the village on the Nigerian border speak both French and English.
Note that this is an estimation since this formula assumes independence and the real probabilities might be different.
