Answer:
13.5
Step-by-step explanation:
When finding radius you would divide the diameter by 2, and the diameter is (3 times 9) 27. Thus 27 divided by 2 = 13.5

Step-by-step explanation:
since the lines only intersect each other once there is one solution at the point (1,4)
Answer:
C - One solution: x = 1, y = 4
Step-by-step explanation:
The solution is where the lines intersect. We can see they only intersect at point, (1, 4), so the answer is C - One solution: x = 1, y = 4.
The harmonic mean of two positive integers is the reciprocal of the arithmetic mean of their reciprocals. For how many ordered pairs $(x,y)$ of positive integers is the harmonic mean of $x$ and $y$ equal to $20$
Answer:
9 ordered pairs
Step-by-step explanation:
The requirement that the harmonic mean of two positive integers be 20 places a restriction on what those integers may be.
20 = 2/(1/x +1/y)
y = 10x/(x -10)
Integer values of x that produce integer values of y are ...
x ∈ {11, 12, 14, 15, 20, 30, 35, 60, 110}
The corresponding 9 ordered pairs are ...
(11, 110), (12, 60), (14, 35), (15, 30), (20, 20), (30, 15), (35, 14), (60, 12), (110, 11)

Factor the binomial expansion. 196x2 + 420x + 225
Answer:
Though many different types of expressions can be classified as binomials, not all of them can be factored. In order to be factorable, a binomial has to have a difference of two squares, a difference of cubes, a sum of cubes, or a greatest common factor.

The measure of angle m is 7 degrees less than the measure of angle n. If the sum of the measures of the two angles is 59° find the measure of each angle
Answer:
Step-by-step explanation:
The measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The measure of angle m is 7 degrees less than the measure of angle n.
m = n - 7 ...(I)
The sum of the measures of the two angles is 59°
m + n = 59 ...(II)
Solving the above two linear equations in two variables by substitution method:
n - 7 + n = 59
2n = 66
n = 33
m = 33 - 7 = 26
Thus, the measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.

To solve the logarithmic inequality below, Braden
decides to first
create a table of values representing the left side of the inequality. Which statements accurately reflect Braden's inequality? Check all that apply.
The domain of the logarithmic expression is x < 2.
The solution set is the interval (5, 14).
When written as two inequalities and graphed, the graphs intersect at (5, 14).
When graphed, the overlapping shading extends to
positive infinity.
The ordered pair (32, 3) could be included in the

(c-7d)2
Answer:
c² - 14cd + 49d²
Step-by-step explanation:
Given
(c - 7d)²
= (c - 7d)(c - 7d)
Each term in the second factor is multiplied by each term in the first factor, that is
c(c - 7d) - 7d(c - 7d) ← distribute both parenthesis
= c² - 7cd - 7cd + 49d² ← collect like terms
= c² - 14cd + 49d²
A rectangle has a length of (2x + 3) cm and a width of (x + 5) cm.
(a) Find an expression for the perimeter of the rectangle.
Answer:
P = 6x + 16
Step-by-step explanation:
the perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width ) , then
P = 2(2x + 3) + 2(x + 5) ← distribute both parenthesis
= 4x + 6 + 2x + 10 ← collect like terms
= 6x + 16

show us a parallelogram ABCD is given.If the diagonals AC and BC interest at O and AO = 4cm, find the length of AC.
plssssssss write the real answer.
Answer:
8 cmStep-by-step explanation:
We know the diagonals of a parallelogram bisect each other.
If O is the point of intersection of diagonals, AC is split into AO and OC.
AC = AO + OCSince AO = OC, the length of AC is:
AC = 2*AO = 2*4 cm = 8 cmAn angle measures 6° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
42° and 48°
Step-by-step explanation:
Complementary angles add up to 90°.
So we have one angle x and the other angle x+6 which when added together will equal 90°.
x + x + 6 = 90
2x + 6 = 90
-6 - 6
2x = 84
Divide both sides by 2
2x/2 = 84/2
x = 42
So one angle = 42°, and the other angle = 42° + 6° = 48°.

An equation that models the decline in the number of US farms is y=3,962,000e−0.02t where t is the number of years since 1960 and y is the number of farms.
The decline in the number of farms means there is a reduction in the number of farms
The number of US farms after 5 years is 3584818
How to determine the number of farmsThe equation that represents the number of farms is given as:
[tex]y=3962000e^{-0.02t[/tex]
After 5 years, the value of t is 5.
So, we have:
[tex]y=3962000e^{-0.02*5[/tex]
Evaluate the product
[tex]y=3962000e^{-0.1[/tex]
Evaluate the exponent
[tex]y=3962000*0.9048[/tex]
Evaluate the product
[tex]y=3584817.6[/tex]
Approximate
[tex]y=3584818[/tex]
Hence, the number of US farms after 5 years is 3584818

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, then Riko will be behind Yuto when 0 ≤ t < 52.5, where t is time in minutes. Explain what this solution means and why t cannot be less than zero.
ANSWER:
The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.
