The graph of an inequality has an open circle at 3.9, and the ray moves to the right. What inequality is graphed?
Answers
Answer:
The required inequality is x > 3.9
Step-by-step explanation:
Consider the provided information.
The closed circle means that the set contain that extreme.
For closed circle we use the inequality "≤" or "≥"
The open circle means that the set does not contain that extreme.
For open circle we use the inequality "<" or ">"
Here, it is given that the graph has an open circle, therefore the required inequality should be "<" or ">"
If the ray moves right, in the usual notation, the real numbers increase to the right, if it moves to left the real numbers decreases.
It is given that the ray moves to right that means the set of numbers bigger than 3.9, that does not contain the number 3.9
Hence, the required inequality is x > 3.9
Where x is any number greater than 3.9.

You try to get a number from 1-10, and you keep moving the decimal in order to accomplish this.
9.081 is in between 1-10. You moved the decimal 6 times, so its 10^6!
Answer:
9.081 x 10^6
Step-by-step explanation:
Now, 10^6 is 1,000,000.
and, 9.081 x 1,000,000 is 9,081,000.
so, 9.081 x 10^6.
-Can you write an equation that relates quarts of blood to weight?
-How can you use the equation to determine solution?
Answers
Step-by-step explanation:
Given that amount of blood is directly linked to body weight of the person.
b = Amount of blood
W = weight of the person
k = proportionality constant or constant of variation
1) Given that, person who weighs 160 lb has about 4.6 quart of blood.
b = 4.6 quart, W = 160 lb
The constant of variation is of value 0.02875 quart/lb.
2) An equation that relates quarts of blood to weight:
3) If, b = ?,W = 175 lb
5.03125 quarts of blood are in the body of a 175-lb person.
w ∝ b
where w = body's weight, b = amount of blood
Changing it into a direct variation becomes
w = kb or k = w/b
where k = proportionality constant
We know that k is obviously constant, we equation it into two states as
w₁/b₁ = w₂/b₂
Given that w₁ = 160 lb, b₁ = 4.6 qt, b₂ = 175, w₂ = 175 lb. Then b₂ will be
160/4.6 = 175/b₂
b₂ = 160/(4.6*175) = 160/805 = 0.20 quarts
Your questions are integrated in just step-by-step solution.

P = (P° x r x (1+r)^N) / ((1+r)^N -1)
where P is the monthly payment, P° is the loan amount, r is the APR, N is the number of monthly payments
We substitute the values and manipulate where one side contains the unknown term r.
27.50/835 = ( r x (1+r)^36) / ((1+r)^36 -1)
Using some functions in the calculator we obtain,
r = 9.51 x 10^-3
Thus, the problem above has an APR of 0.95% monthly.
Answer:
12
Step-by-step explanation:
y = payments per year = 12
c = total interest paid = (36 * 27.50) - 835
m = amount financed = 835
n = total number of payments = 36
It is just a matter of finding the definitions and implementing them.
I get 12.0281484 for the exact result.
so 12 would most likely be the best answer for this.

length = 7x
Perimeter = 10x + 14x = 24x = 96cm
x = 96/24 = 4cm
width = 5x = 20cm
length = 7x = 28cm
Area = (20cm x 28cm) = 560 cm²
