48
Step-by-step explanation:
It's given that Ava takes 4 breaths every 10 seconds.
4 breaths : 10 seconds. ...(1)
To solve this, first we need to calculate how many seconds there are in two minutes.
As 60 seconds make up one minute, 120 seconds make up two.
Now, to solve for the number of breaths (x), we just multiply (1) by 12. We do this so that we get 120 seconds on the right side, so the left side will give us the answer we need.
4 × 12 breaths : 10 × 12 seconds
48 breaths : 120 seconds.
So, the final answer would be 48 breaths.
Hope this helps! :D

Inverse operation
Answer: 9=n
Answer:
n=-9
Step-by-step explanation:
subtract 19 to both sides

Ariana borrows $200 on a 6-year loan.She is charged 5% simple interest per year.How much interest is she charged for 6 years?What is the total amount she has to pay back? PLS HELP
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal (P)= $200
Interst rate (r)= 0.05
Time (t)= 6
First, we need to calculate the total interest using the following formula:
I= P*r*t
I= 200*0.05*6
I= $60
Now, the total debt:
Total debt= P +I
Total debt= 200 + 60
Total debt= $260

2(x-2)-5=3-2x+6
Answer:
x=9/2
Step-by-step explanation:
First distribute 2
2x-4-5=3-2x+6
Add the like terms on the left side -4-5=-9
2x-9=3-2x+6
Do this with the right side 3+6=9
2x-9=-2x+9
Add 9 from the left side to the right side
2x=-2x+18
Then add 2x from the right side to the left side
4x=18
Divide 4 from both sides
x=18/4 or 9/2
Answer:
9/2
Step-by-step explanation:
2x-4-5= 3-2x+6 distribute 2 through the parentheses
2x-4-5=9-2x add the numbers
2x-9=9-2x calculate the difference
2x+2x-9= 9 move variable to left side and change sign
2x+2x= 9+9 move constant to right side and change sign
4x= 18 collect like terms
x=9/2 divide both sides by 4
A baseball team has won 8 out of the first 20 games and has 40 games remaining. The team needs a winning percentage of 62.5% make the playoffs. How many more wins does the team need in order to get into the playoffs? If the team wins the number of games to get into the playoffs, what is the final win percentage if the team wins 2 and loses 3 games in the playoff?
Answer:
30 More Games for Playoffs | Win Percentage of 40% in Playoffs
Step-by-step explanation:
We find the total amount of games by adding first 20 and 40 remaining
This will leave us with 60 games
In order to calculate the playoff, we would have to calculate 62.50% in those 60 games.
62.50% is 5/8, we divide 60 by 8 and get 7.50
We multiply both sides by 7.50 and get 37.50/60
We subtract 8 from 37.50 and get 29.50
We round it to the nearest ones and get 30
In order to win the game they would need to win 30 more games
To calculate the final win percentage, we would add 2 and 3, which would give us 5.
After winning 2 and losing 3,
it would give us 2/5,
which in percentage is 40%

11 is the soln for step 2 as you find that 16=16
The student ends up messing up in step 2
so that rules out b,c and d is also false,because when plugging in 11 to the original, you get a wrong answer.

The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $4600, which was to be divided equally among the members going. Prior to the trip,
10 members decided not to go. If the cost per person increased by $230, how many people went on the expedition?
Let x = number of people that were supposed to go to the trip, where x is greater than or equal to 0.
Let y = price per person initially with x people going on the trip.
xy = 4600
Solve for y.
y = 4600/x
(x - 10)(y + 230) = 4600
Replace y with the fraction 4600/x.
(x - 10)[(4600/x) + 230)] = 4600
What you need to do:
1. Solve (x - 10)[(4600/x) + 230)] = 4600 for x.
2. When you find x, subtract 10 from the value of x to find the number of people that went on the expedition.
You finish.

Tell me the ordered pair for the y intercept
Answer:
(0, 3)
Step-by-step explanation:
The y-intercept is point on the y-axis that the line passes through.
You can see the line passes through 3 on the y-axis.
On the y-axis, every point has a 0 for the x-coordinate.
The ordered pair for the point that is 3 on the y-axis is (0, 3).

radical.
C = 7 cm and a = 4 cm
b= _____ cm
Answer:
√33 cm
Step-by-step explanation:
We know that this is a right triangle, which means that we can apply the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 4 and c = 7, so plug thes in to find b:
a² + b² = c²
4² + b² = 7²
b² = 49 - 16 = 33
b = √33
The answer is thus √33 cm.
help please! pretty easy i just dont remember how to do it
Answer:
Step-by-step explanation:
the disc. is the part under the root in the general formula
which is equal b^2 - 4 x a x c
in this equation a = 1 " coefficient of x^2"
b = 0 "coefficient of x which isn't found here "
c = 12 " the absolute "
[tex]0^{2} - 4[/tex]×[tex]1[/tex]×[tex]12[/tex] = -4×12 = something i don't have a calculator
but it will be negative so the roots will be complex and unreal

. A honeybee leaves the hive, traveling at a speed of 4 mph and returns 1 hour later. What was the distance traveled and the displacement of the honeybee in miles?
Answer:
4milesStep-by-step explanation:
Step one:
given
speed, v= 4mph
time taken t=1 hour
The velocity is defined and the rate of change of displacement
Required:
Distance traveled
we know that the expression relating distance, velocity and time is
velocity= distance/time
distance= velocity* time
substitute we have
Distance=4*1
Distance= 4miles
The distance traveled and the displacement of the honeybee in miles 4miles

Angle ABC has a measure of 125° Angle ABC is rotated 75° about point B to create angle A'B'C'. What is the measure, in degrees, of angle A'B'C
Answer:
m∠A'B'C' is 125°
Step-by-step explanation:
The given parameters are;
The measure of ∠ABC = 125°
The form of transformation applied to ∠ABC = 75° rotation about the point B
Given that a rotation of a geometric figure is a form of rigid transformation, the distance between the coordinates of the points in the preimage are equal to the distance between the coordinates of the points on the image;
Therefore, the angle formed by the ray AB and CB and the angle formed by the ray A'B' and C'B' are equal
From which we have;
m∠ABC = m∠A'B'C' = 125°
