Answer:
Around 5.73. The exact answer is 18/pi. Why? The diameter is twice the radius (2r) The formula of the circumference if 2 pi R
if we divide 18, the circumference by pi, we get the diameter.
Step-by-step explanation:
Answer:
18/π
Step-by-step explanation:
Since 2 × π × r is the circumference of the circle,
2πr = 18
πr = 9
r = 9/π
Since the diameter is 2x the radius,
2r = d
2 × 9/π = d
18/π = d

The line y=px+2 is parallel to the line 2x+y=5. Determine the value of p
Answer:
-2
Step-by-step explanation:
The line y=px+2 has slope p
The line 2x+y=5 can be rewritten as y =-2x+5 so it has slope -2.
Since the two are parallel then they must have the same slope. Hence p=-2.
Answer:
p = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + y = 5 ( subtract 2x from both sides )
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes
Thus for y = px + 2 to be parallel to y = - 2x + 5
Then p = - 2

Step-by-step explanation:
please mark brainliest
Answer:
45=6(5)+t
$15
Step-by-step explanation:
The equation used to describe this situation would be y=6x+t, where y is the total amount Jonny made, x is the number of hours worked, and t is the total tips. The problem tells us that Jonny made $45 total and worked for 5 hours. So, to solve plug these numbers in and solve for t. The number equation looks like, 45=6(5)+t.
Then, to solve first distribute the 6.
45=30+t
Next, subtract 30 from both sides
15=t
That is your final answer, Jonny made $15 in tips.

Answer:
The sum is 17,690 nine
Step-by-step explanation:
8₉ + 2₉ = (10)₉ = (9 + 1)₉ = 11₉
4₉ + 4₉ + 1₉ = (9)₉ = (9 + 0)₉ = 10₉
8₉ + 8₉ + 1₉ = (17)₉ = (9 + 8)₉ = 10₉ + 8₉ = 18₉
8₉ + 8₉ + 1₉ = 18₉
So
8848₉ + 8842₉ = 18801₉

Answer:
x = 7y = 12∠TPS = 140°∠TPQ = 40°∠PRS = 50°Step-by-step explanation:
The marked angles at P are a linear pair, so are supplementary:
(5x +5) +(18x+14) = 180
23x = 161 . . . . . . . . . . . . . . subtract 19
x = 7
Those angle measures are ...
∠TPQ = (5·7 +5)° = 40°
∠TPS = (18·7 +14)° = 140°
__
The marked angle at R is the complement of the acute angle at P, so we have ...
3y +14 +40 = 90
3y = 36
y = 12
∠PRS = (3·12 +14)° = 50°

Step-by-step explanation:
You have to be assured that x really is even. In this case (and the question has a flaw in it) , you assume that x is even. Normally you would multiply x by 2 to get 2x. Now you know it is even, but it is the number not required of you.
So we will assume it is even.

What is a rational function?
In mathematics, a rational function is any function that can be described by using a rational fraction, which is an algebraic fraction such that each the numerator and the denominator are polynomials. The coefficients of the polynomials need no longer be rational numbers; they'll be taken in any field k.
A rational function is one that can be written as a polynomial divided by a polynomial. for the reason that polynomials are defined everywhere, the domain of a rational feature is the set of all numbers except the zeros of the denominator. example 1. f(x) = x / (x - 3). The denominator has only one 0, x = 3.
