How you explain the can you compare how you feel right now with how you felt before we started with the relaxation activity? On a scale 1-5 .5 being the highest rate your level of stress before and after we started with the exercise.Did the levels change?
Answer:
I would rate my feelings 4 on a scale of 5
Step-by-step explanation:
Before exercising I usually feel low and heavily laden with overwhelming thoughts and the feeling doesn't seem to leave except in engage in some form of activities that will take my time and consciousness of time.
Like exercising does take time and it's very engaging one wouldn't know the passage of time while doing some physical task.
It's always relaxing after engaging in physical exercise,I also see it as physical therapy for mental health.

Keiko has a 20% copays for hospital visits after paying her deductible. Assuming she already paid her deductible earlier in the year, how much will she pay (copay) for a hospital bill of $3,291?
A. $328.90
B. $658.20
C. $2,632.80
D. $1,645.50
Answer:
$658.20
Step-by-step explanation:
Money paid in deductible = $3,291
percentage of money to be co-paid = 20% of Money paid in deductible
Thus, she has to 20 percent more which will be 20/100 th part of money paid in deductible.
Solving it we have
Money to be co-paid = 20% of $3,291 = 20/100 * $3,291 = $658.20
Thus, Keiko will pay (copay) $658.20 for the hospital bill

Find an equivalent expression to 7y + 28x
Samantha just opened a new restaurant. She earned $550 on the first day and $750 on the third day that she was open for business. If Samantha's earnings continue to increase at the same rate, by how much are her earnings increasing each day? $________ per day Show your work. HINT: Find the slope.
Answer:
Step-by-step explanation:
If Samantha's earnings continue to increase at the same rate, this means that her earning is increasing arithmetically.
If she earned $550 in the first day, we can say the first term is $550
If she earned $750 on the third day, we can say the third term is $750
For us to know by how much her money is increasing, we need to find the common difference d formed by the sequence
550, x , 750
T1 = 550
T2 = x
T3 = 750
Common difference d = T2-T1 = T3-T2
x - 550 = 750 - x = d
Let's calculate the second term first i.e x
Since x - 550 = 750 - x = d
x - 550 = 750 - x
Collect like terms
x+x = 750+550
2x = 1300
x = 1300/2
x = 650
d = T2-T1
d = x - T1
d = 650-550
d = 100
Hence her money keeps increasing by $100 each day

Triangle ABC is transformed to triangle A′B′C′, as shown below:
A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Which equation shows the correct relationship between the measures of the angles of the two triangles?
The measure of angle CAB = The measure of angle C prime B prime A prime
The measure of angle BCA = The measure of angle A prime B prime C
The measure of angle CAB = The measure of angle C prime A prime B prime
The measure of angle BCA = The measure of angle C prime A prime B prime low
Answer:
The measure of angle BCA = The measure of angle A prime B prime C
can someone help me? i'm confunsed and I don't know anything
Answer:
See Below
Step-by-step explanation:
ABCD primes all correspond to x and y values on the graph.
A=
B=
C=
D=
1) y- intercept
2) time of max height
3) time when balloon hits ground
4) x-intercept
5) max height
6) Initial height
So lets look at (0,A)
This would count as the y - intercept as well as the height they started throwing the balloons.
Soo....
A = y-intercept; Initial height
Now, (B,C)
This is the highest point on the graph, therefore it would be the max time and max height.
If we look at this as a person behind the line throwing the ballon, the y would be the height and the x would be the time
B = Time of max height
C=Max height
(D,0)
From the visual above, this point would be where the balloon hits the ground
From the visual in our head, x is time and y is height
Since d is the x, it is the time when the balloon hits the ground. And since
y =0, D is also the x intercept
D = x intercept, Time when balloon hits ground
Therefore,
A = y-intercept; Initial height
B = Time of max height
C=Max height
D = x intercept, Time when balloon hits ground
Hope this helps! =D
The next model of a sport car will cost 3.6% more than the current model. The current model cost $42,000. How much will the price in dollars? What will be the price of the next model
Answer:
$43,512
Step-by-step explanation:
3.6% = 0.036
0.036 * 42,000 = 1,512
42,000 + 1,512 = 43,512

Suppose that 24 inches of wire costs 96 cents.
At the same rate, how much (in cents) will 47 inches of wire cost?
Answer:
Step-by-step explanation:
24inches = 96 cents
To find the cost of 1 inch, divide 96 cents by 24.
1 inch = 96/24 = 4 cents
Then to find the cost of 47 inches, multiply by 4.
47 inches = 47 x 4 = 188 cents.
Sarah has to pay a one-time $300 deposit for her apartment. Each month she pays $700 for rent. How much would Sarah pay for “n” months?
Answer:
700n + 300
Step-by-step explanation:
We know that no matter what happens, Sarah has to pay a One-Time $300 for her deposit.
Now, we know that for every month she stays in the apartment, it will cost her $700.
So, we can come up with a formula to find out how much she would pay:
700n + 300

3) $50.40
Step-by-step explanation:
2)
[tex] \frac{4}{12} + \frac{10}{7} = \frac{37}{21} \div 2 = \frac{37}{42} [/tex]
this is for x
[tex] \frac{5}{2} + \frac{4}{7} = \frac{43}{14} \div 2 = \frac{43}{28} [/tex]

An equation is shown below:
4(x − 3) − 5(x + 1) = 3
Which statement shows a correct next step in solving the equation?
The equation can become 4x − 3 − 5x + 1 = 3 by applying the associative property of multiplication.
The equation can become 4x − 3 − 5x + 1 = 3 by applying the distributive property.
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Answer:
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Step-by-step explanation:
By applying the distributive law to this equation, we can produce the equation :
4x − 12 − 5x − 5 = 3;
The distributive property is a mathematical function in which each element in the parentheses is multiplied by the one outside of it;
4(x − 3) − 5(x + 1) = 3
In the equation;
4 distribute over the first parentheses and -5 over the second one;
So we expand;
4x - 13 - 5x -5 = 3
In distributive property, expansion simply takes place.
