Answer:
The Inverse variation says that:
,
then the equation is of the form:
or
Here, r represents the number of roses and w represents the number of weeds.
As per the statement:
The number of roses (r) in a garden increases when the number of weeds (w) decreases.
by definition of inverse variation:
....[1]
From the given table:
take any points
r = 20 and w = 10 then;
Substitute in [1] we have;
Simplify:
k = 200
The equation becomes:
We have to find the number of roses when there are 5 weeds.
⇒w = 5
then;
Divide both sides by 5 we get;
r = 40
Therefore, the number of roses are 40 when there are 5 weeds.

Answer:
Step-by-step explanation:
We know that the whole arc is equal to 360°, that means
Where ,
and
. Replacing these expressiones, we have
But, arc ABC is defined by the sum of arcs AB and BC:
Therefore, the measure of arc ABC is 283°.
Answer:
Arc measure of ABC is 283°
Step-by-step explanation:
We know the total angle of the circle is 360°.
Therefore,
(20y - 11) + (4y +6) + (7y - 7) = 360°
Collecting like terms, we have:
20y + 4y + 7y = 360 + 7 - 6 + 11
31y = 372
Let's divide both sides by 31.
y = 12
The arc measure of ABC is the sum of AB and BC. To find the arc measure of ABC, we have:
(4y +6) + (20y - 11)
Collecting like terms, we have:
4y + 20y + 6 - 11
24y - 5
Let's substitute 12 for y
24(12) - 5
288 - 5 = 283°
Arc measure of ABC is 283°
