Amber is on a family cell phone plan with the other 3 members of her family. The family gets 840 shared cell phone minutes a month, and each family member is limited to his or her equal share of the minutes. The only free calls are calls between family members.
How many minutes per day can Amber talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes?
Minutes per day can Amber talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes will be 7 minutes
ConceptFirst of all we will find the total minutes per family member will get by dividing the total minutes of cell phone plan to total family memberAfter finding total minutes each family member will get we will divide it by 30 to get how many minutes per day Amber will get to talk on her cell phone with her friend.How to solve this problem?The steps are as follow:
Given, there are total 4 family members including Amber.Also the family gets 840 minutes shared cell phone minutes for a monthTo find total minutes per family member we will using following formula:total minutes per family member = total minutes / number of family member
total minutes per family member = 840 / 4
total minutes per family member = 210 minutes
To find the minutes per day Amber will get we will use following formula:Minutes per day Amber will get = total minutes per family member / total days in month
Minutes per day Amber will get = 210 / 30 = 7 minutes per day
So Amber will get 7 minutes per day to talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes

What is the momentum of a 1.5-kg ball rolling at 3.0m/s
Answer:
4.5 kg m/s
Step-by-step explanation:
[tex]Momentum = mass \times velocity \\ \hspace{60 pt} = 1.5 \times 3.0 \\\hspace{60 pt} = 4.5 \: kg \: m/s[/tex]
Final answer:
The momentum of a 1.5-kg ball rolling at 3.0 m/s is calculated by multiplying the mass by the velocity, resulting in 4.5 kg*m/s.
Explanation:
The momentum of an object is calculated using the formula momentum (p) = mass (m) * velocity (v). Applying this formula to the given problem, where a 1.5-kg ball is rolling at a speed of 3.0 m/s, the momentum can be found by multiplying the mass of the ball by its velocity.
So, the momentum p is given by:
p = 1.5 kg * 3.0 m/s = 4.5 kg*m/s.
Therefore, the momentum of the 1.5-kg ball rolling at 3.0 m/s is 4.5 kilogram meters per second (4.5 kg*m/s).
Tim's piggy bank contains dimes and nickels worth $5.50. He has 70 coins in all. Use substitution to solve the system of equations to find out how many of each coin Tim has.
Tim has a total of 30 nickels and 40 dimes.
What is Linear Equation?Linear equations are the equations which consist of two or more variables having the exponent of the variable equals 1.
Total number of coins in the Tim's piggy bank = 70 coins
Let d be the number of dime coins and n be the number of nickel coins.
So d + n = 70
Total dollars = $5.50
10 dimes = 1 dollar
1 dime = 1/10 dollar = 0.1 dollar
20 nickels = 1 dollar
1 nickel = 1/20 dollar = 0.05 dollar
0.1 d + 0.05 n = 5.50
So we have two linear equations here : d + n = 70 and 0.1 d + 0.05 n = 5.50.
d + n = 70 ⇒ d = 70 - n
Substituting d = 70 - n in the equation 0.1 d + 0.05 n = 5.50,
0.1 (70 - n) + 0.05 n = 5.50
(0.1 × 70) - 0.1n + 0.05n = 5.50
7 - 0.05n = 5.50
-0.05n = -1.5
n = 30
So d = 70 - n = 70 - 30 = 40
Hence the number of nickel coins is 30 and number of dime coins is 40.

How many pairs of vertical angles are formed by five distinct lines that have a common point of intersection?
The total number of pairs of vertical angles formed by five distinct lines that have a common point of intersection is: 10 pairs.
To find how many pairs of vertical angles are formed by five distinct lines that all intersect at a common point, we need to understand a few key concepts about vertical angles and intersecting lines.
Intersection Point: When multiple lines intersect at a single point, they form various angles at that point.Vertical Angles Definition: Vertical angles are the angles that are opposite each other when two lines intersect. They are congruent (having the same measure).Pairs of Intersections: Each pair of lines forms a set of vertical angles at the intersection point.Number of Intersecting Pairs: With five distinct lines, any two lines can form an intersection. The number of ways to choose 2 lines out of 5 to intersect can be calculated using the combination formula:
[tex]\binom{n}{2} = \frac{n(n-1)}{2}[/tex]
Where [tex]n[/tex] is 5 in this case.
Calculation: Plugging in the values, we get:
[tex]\binom{5}{2} = \frac{5 \cdot 4}{2} = 10[/tex]
So, there are 10 pairs of intersecting lines.
Vertical Angle Pairs per Intersection: For each of these 10 intersections, there is exactly one pair of vertical angles.
Each intersection of two lines forms one pair of vertical angles, and with 10 intersections, we have 10 pairs of vertical angles.

two lines meet at a point that is also the endpoint of two rays. setup and solve the appropriate equations to solve for the values of angles x and y. show the steps you followed to find the unknown angles.
Answer:
x = 19°
y = 53°
Step-by-step explanation:
First we can find the value of x, then the value of y.
For x, we can observe from the figure that x is complementary to the angle of 71°, that is, they both summed have 90°.
So, we have that:
x + 71 = 90
x = 19°
Now we can solve for y.
From the figure we have that y is supplementary to the angle (37° + 71° + x°), that is, they summed form a angle of 180°.
So we have that:
y + 37 + 71 + 19 = 180
y = 180 - 37 - 71 - 19 = 53°
The angles x and y lie on a straight line at the intersection point of two lines and are therefore supplementary. Therefore, they add up to 180 degrees. Without further information, it's impossible to find the exact values of X or Y.
Explanation:Given that two lines intersect at a common point, and this point is also the end point of two rays, we create four angles around the intersecting point. Let's denote the angles formed by the intersecting lines as angle x and angle y. According to the properties of intersecting lines, adjacent angles are supplementary. Therefore, the measures of x and y add up to 180 degrees. We set up the equation as x + y = 180. Without any additional information, we cannot find the specific values of x and y. However, we can say that whatever the value of x is, y will be 180 - x, and vice versa.

A person walking starts 0 m/s and after 6 seconds is traveling at
5 m/s. What is the acceleration of the walker?
Final answer:
To find the acceleration, we subtract the initial velocity from the final velocity and then divide by the time. For the given values, this results in an acceleration of 0.833 m/s² for the walker.
Explanation:
The student has asked about the acceleration of a person who starts at 0 m/s and reaches 5 m/s in 6 seconds. To find acceleration, we use the formula:
acceleration = (final velocity - initial velocity) / time
Inserting the given values:
acceleration = (5 m/s - 0 m/s) / 6 s = 5/6 m/s²
Therefore, the acceleration of the walker is 0.833 m/s².

2n-9.2 =n+4/5
Answer:
1, 3, 5
Step-by-step explanation:
Let the number be n
1.Twice a number minus nine and two tenths is the same as the number plus four fifths.
Twice a number is 2n. nine and two tenth = 9.2. Therefore twice a number minus nine and two tenths = 2n - 9.2. the number plus four fifths = n + 4/5
The resulting equation is 2n-9.2 =n+4/5
2.Nine point two decreased by double a number is the same as the number added to four fifths.
Nine point two = 9.2, double a number = 2n. Therefore, Nine point two decreased by double a number is 9.2 - 2n
The resulting equation gives 9.2 - 2n = n + 4/5
3.Nine point two less than twice a number is equal to the number added to four fifths.
Nine point two = 9.2, twice a number = 2n. Therefore Nine point two less than twice a number = 2n - 9.2
The resulting equation is 2n-9.2 =n+4/5
4.Two times the difference of a number and nine and two tenths is equal to the number plus four fifths.
The difference of a number and nine and two tenths is given by n - 9.2. Therefore, Two times the difference of a number and nine and two tenths is 2(n - 9.2).
The resulting equation is 2(n - 9.2) = n + 4/5
5.Double a number decreased by nine and two tenths is the same as the sum of four fifths and the number.
Double a number decreased by nine and two tenths is 2n - 9.2
The resulting equation is 2n-9.2 =n+4/5
Answer:
1 Twice a number minus nine and two-tenths is the same as the number plus four-fifths.
3 Nine point two less than twice a number is equal to the number added to four-fifths.
5 Double a number decreased by nine and two-tenths is the same as the sum of four-fifths and the number.
