The expression -120+13m represents a submarine that began at a depth of 120 feet below sea level and ascended at a rate of 13 feet per minute. What was the depth of the submarine after 6 minutes?
Answer: The depth was 42 feet below see level after 6 minutes
Step-by-step explanation:
If m represents the minutes then input 6 for m into the expression and solve.
-120 + 13(6)
-120 + 78 = -42
One glass of milk gives you 3/10 of the recommended amount of calcium per day.
3 glasses of milk will give you what fraction of the recommended amount of calcium per day?
O A. 3/5
OB. 1/10
O C. 19/30
• D. 9/10
Answer:
The answer is D. 9/10
Step-by-step explanation:
The reason why is because the numerator 3 multiplied by 3 gives you 9 and the denominator doesn't change, so the answer is 9/10.

Answer:
D. [tex]\frac{10}{15}[/tex] and [tex]\frac{14}{21}[/tex]
Step-by-step explanation:
Proportional ratios are ratios that represent the same relationship. One way to check this is to reduce the ratios, because if they are proportional, they will equal the same thing. Both [tex]\frac{10}{15}[/tex] and [tex]\frac{14}{21}[/tex] simplify to [tex]\frac{2}{3}[/tex].

Paul wants to estimate the mean number of siblings for each student in his school. He records the number of siblings for each of 100 randomly selected students in the school. What is the parameter?
Answer:
A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.
In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.
For example, in a table:
#student #siblings.
1 3
2 1
3 4
... ...
In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.

REASONING A high school band was selling ride tickets for the school fair. On the first day, 250 children’s tickets and 150 adult tickets were sold for a total of $550. On the second day, 180 children’s tickets and 120 adult tickets were sold for a total of $420. What is the price for each child ticket and each adult ticket?
a. Select a system of equations to represent this situation. Let x represent the cost of children’s tickets and y represent the cost of adult tickets.
A)
250x+120y=550 ; 180x+150y=420
B)
180x+150y=420 ; 180x+120y=420
C)
250x+150y=550 ; 180x+120y=420
D)
250x+150y=420 ; 180x+120y=550
The system of equation should be C) 250x+150y=550 ; 180x+120y=420
Important information:On the first day, 250 children’s tickets and 150 adult tickets were sold for a total of $550.

On Gabriela's first birthday, her parents gave her a $50 savings account on every birthday after that her parents added to the account,
increasing the amount they deposited by $25 each year. Complete the recursive definition for the sequence that represents this situation by
finding the values for a, and d.
Initial amount , a = $50 .
Increase in price , d = $25 .
We need to find the recursive relation of the sequence .
If we notice it is an arithmetic progression with common difference $25 .
Which means that difference between any two consecutive term is 25 .
So , T(n) - T(n-1) = 25
T(n) = T(n-1) + 25 .
Hence , this is the required solution .

Serena estimates that she can paint 60 square feet of wall space every half-hour. Write an equation for the relationship with time in hours as the independent variable x and the square footage she can paint as the dependent variable y. Can she paint 400 square feet in 3.5 hrs
Answer:
So, the relationship with i hours as the indecent variables would be
Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.
Step-by-step explanation:
Since we have given that
Area that she can paint = 60 square feet
Time taken = half hour = 30 minutes = 0.5 hours
Using "Unitary method, we get that
In 0.5 hours, she can paint = 60 square feet
In 1 hour, she can paint =
In i hours, she can paint =
Let the total area she can paint be 'y'.
So, the relationship with i hours as the indecent variables would be
Now, Can Serena paint 400 square feet of wall space i. 3.5 hours
We put y = 400 and i = 3.5 hours to check whether it is equal or not.
Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Let's solve your equation step-by-step.
3x−5x+14=26
Step 1: Simplify both sides of the equation.
3x−5x+14=26
3x+−5x+14=26
(3x+−5x)+(14)=26(Combine Like Terms)
−2x+14=26
−2x+14=26
Step 2: Subtract 14 from both sides.
−2x+14−14=26−14
−2x=12

a clock is circular in shape with diameter of 25 cm. find the length of the arc between the markings 12 and 5 rounded to the nearest tenth cm
Answer:
32.7 cm
Step-by-step explanation:
For central angle θ in radians, the arc length is given by ...
s = rθ
The angle between 12 and 5 is 5π/6 radians, and the radius is 25/2 cm, so the arc length is ...
s = (25/2 cm)(5π/6) = (125/12)π cm ≈ 32.7 cm
The arc length between the markings is about 32.7 cm.
Solve for x in the equation: 5x +14 = 2x - 4
Someone help
Answer:
x = -6
Step-by-step explanation:
5x +14 = 2x - 4
Subtract 2x from each side
5x-2x +14 = 2x-2x - 4
3x +14 = -4
Subtract 14 from each side
3x+14-14 = -4-14
3x = -18
Divide each side by 3
3x/3 = -18/3
x = -6
Answer:
x = -6
Step-by-step explanation:
5x+ 14 = 2x - 4
-2x -2x
3x+14= -4
-14 -14
3x = -18
3x/3 = -18/3
x = -6
Sari estimated the quotient of 120.78 ÷ 9.9 to be 12. She said that her estimate is slightly greater than the actual answer. Is she correct? Is her estimate reasonable? Explain.
Answer:
Yes, her estimate is greater than the actual answer. 120.78/9.9 = 12.2. Since 12.2 (the actual answer) is greater than her estimate of 12, she is correct.
Step-by-step explanation:
See Answer.
Answer:
yo
Step-by-step explanation:
Sari had a good estimate for the problem. But she was not correct in saying that her answer was slightly greater than the actual answer. The rounded dividend, 120, is slightly less than 120.76, and the rounded divisor, 10, is slightly greater than 9.9, so the estimate would be less than the actual quotient.

Let f(x) = 5x - 4 and g(x) = x^2- 1. Find (g•f)(0).
Answer:
[tex](g\cdot f)(0)=4[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=5x-4\text{ and } g(x)=x^2-1[/tex]
And we want to find:
[tex](g\cdot f)(0)[/tex]
This is the same as:
[tex]=g(0)\cdot f(0)[/tex]
So, find g(0) and f(0):
g(0):
Substitute 0 into g(x):
[tex]g(0)=(0)^2-1[/tex]
Square:
[tex]g(0)=0-1[/tex]
Subtract:
[tex]g(0)=-1[/tex]
And f(0):
Substitute 0 into f(x):
[tex]f(0)=5(0)-4[/tex]
Multiply:
[tex]f(0)=0-4[/tex]
Subtract:
[tex]f(0)=-4[/tex]
So, our equation is now:
[tex](g\cdot f)(0)=g(0)\cdot f(0)=(-1)\cdot(-4)[/tex]
Multiply:
[tex]=4[/tex]
So, our answer is 4.

The width of a rectangle measures 9.7 X -4.7 centimetersAnd the length measures 2.9 X +6.4 cm which expression represents the perimeter in centimeters of the rectangle
Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.

Berks Lanes charges $4 per game of bowling and
$5 for the shoe rentals. If Roberto met his friends
to play and paid for 5 games and one shoe rental,
how much did he pay in all?
PLZ HELP THIS IS DUE IN 8 MINUTESSSSS
Answer:
25 $.
Step-by-step explanation:
4 (dollars per game) x 5 (how much games) = 20.
+ 5 $ for one shoe rental.
Robert will pay $25 for 5 games and one shoe rental.
Given that,
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals. Roberto paid for 5 games and one shoe rental, how much did he pay in all is to be determined.
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals
Let the number of games be x, and number of show use be y
Total cost for the games = 4x + 5y
Roberto paid for 5 games and one shoe rental implies
x = 5 and y = 1
Now,
Total money paid = 4 * 5 + 5 * 1
= 25
Thus, robert will pay $25 for 5 games and one shoe rental.
