The inequality will be:
6.2 + v ≥ -4.7
And it can solved to get:
v ≥ -10.9
How to write the inequality?Here we have the mathematical sentence:
"The sum of a number v and 6.2 is at least -4.7"
The sum is written as:
6.2 + v
And that is equal to or more than -4.7, then we need to use the symbol ≥, with that, we can write the inequality:
6.2 + v ≥ -4.7
Solving that four our number v, we get:
v ≥ -4.7 - 6.2
v ≥ -10.9

When extended, the periscope of a submarine is about eighteen feet above sea level. When retracted, the top of the periscope is ten feet below sea level. Suppose that a number line is used to represent this situation, with sea level at zero. Which number sentence describes the relationship between the distance from the surface to the top of the periscope when it is extended and the distance from the surface of the water to the top of the periscope when it is retracted?
The position of the periscope on the number line will lie at negative 10 for below sea level and at 18 for above sea level.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."
It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that a submarine's periscope rises around 18 feet above sea level when fully deployed. The peak of the periscope is 10 feet below sea level when it is fully extended.

adrian decorated 16 cupcakes in 28 minutes. if he continues at this pace, how many minutes will it take him to decorate 56 cupcakes?
Solution :
98 minutes will it take him to decorate 56 cupcakes
Time and Work – Introduction and Concept
Time and work deal with the time taken by an individual or a group of individuals to complete a piece of work and the efficiency of the work done by each of them.
Work Done = Time Taken × Rate of Work
Rate of Work = 1 / Time Taken
Time Taken = 1 / Rate of Work
If a piece of work is done in x number of days, then the work done in one day = 1/x
Total Work Done = Number of Days × Efficiency
Efficiency and Time are inversely proportional to each other
X:y is the ratio of the number of men who are required to complete a piece of work, then the ratio of the time taken by them to complete the work will be y:x
Adrian decorated 16 cupcakes = 28 minutes
adrian decorated 1 cupcakes = 28 minutes /16
Adrian decorated 56 cupcakes = 28 minutes /16 x56
= (28/16)x56
[tex]=\frac{28}{16} .56\\\\[/tex]
= 14/8. 56

3. Maria wants to write a linear function to describe the cost of a cab ride. The cab costs $3 per ride plus an additional $0.20 per mile. a. What is the function that describes the cost of the cab ride for any number of miles? b. how much is the fare for a 15-mile trip? c. How far can she afford to travel if she only has 10$
Answer:
a. [tex]f(x) = 3 + 0.2x[/tex]
b. 6$
c. 35 miles
Step-by-step explanation:
There is a fixed price of $3 per ride, therefore, the y-intercept of the function would be $3, as she has to pay that amount for any amount of miles ridden in the cab.
In addition, she must add an extra $0.2 for every mile she has ridden in the cab. We can represent the amount of miles using the parameter [tex]x[/tex].
Therefore, the function to represent the cost of a cab-ride would be [tex]f(x) = 3 + 0.2x[/tex].
b. To find out how much she must pay for a 15-mile trip, we must substitute [tex]x = 15[/tex], as she has ridden 15 miles in the cab.
[tex]f(x = 15) = 3 + 0.2 \times 15 \to 3 + 3 \to 6[/tex]
She must pay $6 for the ride.
c. To find out how far she can travel if she only has $10, we would have to equalize the function to 10, as that is the final price she has to pay.
[tex]f(x) = 10\\\to 3 + 0.2x = 10\\\to 0.2x = 7\\\to x = 35[/tex]
For $10, she can travel 35 miles.
Answer: For $10, she can travel 35 miles.

Nine friends go out to watch a movie at a movie theatre. Each row of the movie theatre has 10 seats but the last sit on the row has been reserved for a special guest. The friends will sit on the remaining seats. 5.1. How many ways can they arrange themselves on these remaining seats?
Nine friends can arrange themselves on the nine rows of movie theatre in 362,880 ways.
What is defined as the combination?A combination is a method of selecting objects from a collection in which the order of choice is irrelevant.The combination is described as "an arrangement of objects in which the order where the objects are chosen is unimportant." The combination means "selection of things," where the order is irrelevant.Combination is an a kind of permutation in which the order of such selection is ignored. As a result, the number of permutations is always greater than the amount of combinations.For the given question;
The total number of friends went to watch movie = 9.
The initial number of seats in movie theatre = 10
The seats left after the removal of one seat = 9
Thus, the nine friends can arrange on the 9 seats in 9! ways.
9! = 9×8×7×6×5×4×3×2
9! = 362,880
Therefore, the possible arrangement of 9 friends on remaining seats is 362,880.

The amount of oil imported to Country A from Country B in millions of barrels per day can be approximated by the
equation y = 0.064x + 1.49, where x is the number of years since 1975. Solve this equation for x. Use the new equation
to determine in which year the approximate
number of oil barrels imported from Country B per day will be 4.05 million.
The year in which the approximate number of oil barrels imported from Country B per day would be 4.05 million is 2,015.
What is a linear equation?A linear equation can be defined as an algebraic equation of the first order that has two (2) variables (x, y) with each of its term having an exponent of one (1).
In Mathematics, the standard form of a linear equation is given by the following:
y = mx + c
Next, we would solve the given linear equation for x:
y = 0.064x + 1.49
Subtracting 1.49 from both sides, we have:
4.05 - 1.49 = 0.064x + 1.49 - 1.49
4.05 - 1.49 = 0.064x
2.56 = 0.064x
x = 2.56/0.064
x = 40.
The year in which the approximate number of oil barrels imported from Country B per day would be 4.05 million is given by:
y = 1975 + x
y = 1975 + 40

To find the percentage of boys in the class, we must know how many boys are in the class.
The class has a total of 45 students. 15 of those students are females, so we know to 45 - 15 is the number of boys.
45-15=30
So now we now that there are 30 boys. To be more specific, 30 boys out of the 45 students. We can look at this as a fraction, which can be changed to a percentage/decimal. ([tex]\frac{30}{45}[/tex])

Joe, Thea, and Taylor invested in a partnership in the ratio 1:2:3, respectively. Years later, when the partnership was worth $1.2 million, Thea decides to go to graduate school and sells her part of the partnership to Joe. How much would Joe need to pay Thea to buy her share of the business?
Jeo need to pay $0.4 million to buy Thea’s share.
Given,
Ratio of investment of Joe, Thea, Taylor in the partnership = 1:2:3
Worth of partnership after some years = $1.2 million
Now, we can calculate the share of partners:
Total of investment = 1 + 2 + 3 = 6
1.2 / 6 = 0.2 million, this is the investment.
Now share of partners:
Joe’s share = 0.2 x 1 = $0.2 million
Thea’s share = 0.2 x 2 = $0.4 million
Taylor’s share = 0.2 x 3 = $0.6 million
From the above data’s we can conclude that Joe needs $0.4 million to buy Thea’s share.

Answer:
4/5
Step-by-step explanation:
In order to turn a decimal, in this case 0.8, you'll need to look at the placement of the decimal first. The placement of the decimal here is in the tenths. Thus meaning we will use 10 as the denominator. For the numerator you will use 8. Now we have 8/10. To simplify 8/10 you will divide 8/10 by 2. 8 divided by 2 is 4 (now the numerator). and 10 divided by 2 is 5 (now the denominator). 0.8 would be 8/10 as a fraction and the simplified version of 8/10 is 4/5.
