A pool measuring 8 meters by 24 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 720 square meters, what is the width of the path? 8 + 2x 8 24 - 2x
The Width of the path is ____ meters
The real answer is 6
Step-by-step explanation:
the width of the path is 6 meters.
Let's assume the width of the path is represented by 'x' meters.
The overall dimensions of the combined pool and path would be:
Width = 8 + 2x
Length = 24 + 2x
To calculate the area of the combined pool and path, we multiply the width and length:
Area = (8 + 2x) * (24 + 2x)
Given that the area is 720 square meters, we can set up the equation:
(8 + 2x) * (24 + 2x) = 720
Expanding the equation:
192 + 16x + 48x + 4x² = 720
4x² + 64x + 192 = 720
Rearranging the equation:
4x² + 64x - 528 = 0
Now we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. After solving the equation, we find that x = 6.
Therefore, the width of the path is 6 meters.

19c + 31 = 26c - 74
solve for c
Answer:c
c = - 15
Step-by-step explanation:
Simplifying
19c + 31 = 26c + -74
Reorder the terms:
31 + 19c = 26c + -74
Reorder the terms:
31 + 19c = -74 + 26c
Solving
31 + 19c = -74 + 26c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-26c' to each side of the equation.
31 + 19c + -26c = -74 + 26c + -26c
Combine like terms: 19c + -26c = -7c
31 + -7c = -74 + 26c + -26c
Combine like terms: 26c + -26c = 0
31 + -7c = -74 + 0
31 + -7c = -74
Add '-31' to each side of the equation.
31 + -31 + -7c = -74 + -31
Combine like terms: 31 + -31 = 0
0 + -7c = -74 + -31
-7c = -74 + -31
Combine like terms: -74 + -31 = -105
-7c = -105
Divide each side by '-7'.
c = 15
Simplifying
c = - 15
corey tracks heart rate after coming off the ice in a hockey game. in 1/6 minute, her heart beats 26 times.
Answer:156
Step-by-step explanation: 26÷1/6 =26×6 =156
The intensity level is moderate
In one second Corey's heart will beat 3 times.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Corey's heart beats 26 times in 1/6 minutes.
Assume that her heart beats [x] times in 1 second. Then -
1/6 of minute = 1/6 x 60 = 10 seconds
In 10 seconds, her heart beats 26 times
So, in one second, her heart will beat (26/10) = 2.6 times = 3 times (approx.).
Therefore, in one second Corey's heart will beat 3 times.

A superstar major league baseball player just signed a new deal that pays him a record amount of money. The star has driven in an average of 110 runs over the course of his career, with a standard deviation of 31 runs. An average player at his position drives in 80 runs. What is the probability the superstar bats in fewer runs than an average player next year
Answer:
0.1667
Step-by-step explanation:
Given that:
Average / mean runs (m) = 110 runs
Standard deviation (σ) = 31 runs
Number of runs driven in by an average player in his position = 80
The probability the superstar bats in fewer runs than an average player next year will be the :
P(x < 80)
Zscore = (x - mean) / σ
Zscore = (80 - 110) / 31
Zscore = - 30 / 31
Zscore = - 0.9677419
P(Z < 0.9677419) = 0.1666 ( from z probability calculator)
= 0.1667
What is R,S,W? I really need help!
Answer:
R- 73°
S- 73°
W- 138°
Step-by-step explanation:
Every triangle is 180°.
So 65+42=107
180-107=73
So that's the triangle to the right.
Now the other one is identical.
So we know the line w is on is 180°
On the corner w is on it took up 42°
So 180-42= 138° (which is 'w')

Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms?
Answer:
If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant.

Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%. What was the time, using exact interest? (Do not round intermediate calculations. Round up your answer to the nearest day.)
Step-by-step explanation
Note that
Interest is represented by I=1326
The principal is represented by P=47,600
Rate is R =4%
And Time is year
Interest is calculated using the formulae,
I =PRT/100
From the above formulae, time can be calculated as
T=100I/PR
T= 100×1326/(47600×4)
T= 132600/190400
T= 0.6964 years
To convert to days, multiply by 365(since those no of days make a year)
T= 0.6964×365=254 days
This was approximated to the nearest day
Answer is 254 days
