Do I have this right this my last question I need help
Answer:
Yes, it is
Step-by-step explanation:
For the first part is 10 per people = y = 10x
And the second part is 2 per people = y = 2x
So the two equations are
y = 10x
and
y = 2x

If G is the incenter of triangle ABC, find each measure
Answer:
m∠ABG = 20 degrees
m∠BCA = 22 degrees
m∠BAC = 118 degrees
m∠BAG = 59 degrees
DG = 4
BE = 12.4
BG = 11.7
GC = 20.4
Step-by-step explanation:
The given parameters are;
m∠CBG = 20°, m∠BCG = 11°
The incenter of a triangle is the point where the three bisectors of ΔABC meets
m∠ABG = m∠CBG = 20° by definition of angle bisector
m∠ABG = 20°
m∠ACG = m∠BCG = 11° by definition of angle bisector
m∠BCA = m∠ACG + m∠BCG = 11° + 11° = 22°
m∠ABC = m∠ABG + m∠CBG = 20° + 20° = 40°
m∠BAC = 180° - (m∠BCA+m∠ABC) = 180° - (40° + 22°) = 118°
m∠BAG = m∠CAG by definition of angle bisector
m∠BAC = 118° = m∠BAG + m∠CAG = m∠BAG + m∠BAG = 2 × m∠BAG
2 × mBAG = 118°
m∠BAG = 118°/2 = 59°
m∠BAG = 59°
Given that "G" is the incenter of the triangle ABC, we have;
GF = GE = DG = The radius of the incircle of the triangle = 4
Therefore, by Pythagoras' theorem, we have;
BG = √(11² + 4²) = √137 ≈ 11.7
BE = √((BG)² + 4²) = √(137 + 4²) = √153 ≈ 12.4
GC = √(20² + 4²) = √416= 4·√26 ≈ 20.4
Applying the definition of the incenter of a triangle, the measures in triangle ABC where G is the incenter are:
[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex][tex]\mathbf{m \angle BCA = 22^{\circ}}[/tex][tex]\mathbf{m \angle BAC = 118^{\circ}}[/tex][tex]\mathbf{m \angle BAG = 59^{\circ}}[/tex]DG = 4BE = 10.99BG = 11.7GC = 20.4Recall the following facts about the incenter of a triangle:
The incenter of a triangle is the point where the three angle bisectors that divides each angle vertex into two intersect each other.
The incenter also, is a point equidistant to all three sides of the triangle at right angle.
Applying the properties above, the measures in the image can be calculated as shown below.
Given:
[tex]m \angle EBG = 20^{\circ}\\\\m \angle ECG = 11^{\circ}\\\\CF = 20\\\\EG = 4\\\\BD = 11[/tex]
Find [tex]m \angle ABG[/tex]:
[tex]m \angle ABG = m \angle EBG[/tex] (angle bisector definition)
Substitute[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex]
Find [tex]m \angle BCA[/tex]:
[tex]m \angle BCA = 2(m \angle ECG)[/tex] (angle bisector definition)
Substitute[tex]m \angle BCA = 2(11)\\\\\mathbf{m \angle BCA = 22^{\circ}}[/tex]
Find [tex]m \angle BAC[/tex]:
[tex]m \angle BAC = 180 - (m \angle CBA + m \angle BCA)[/tex] (sum of triangle definition)
Substitute[tex]m \angle BAC = 180 - (40 + 22)\\\\\mathbf{m \angle BAC = 118^{\circ}}[/tex]
Find [tex]m \angle BAG[/tex]:
[tex]m \angle BAG = \frac{1}{2} (m \angle BAC)[/tex] (angle bisector definition)
Substitute[tex]m \angle BAG = \frac{1}{2} (118)\\\\\mathbf{m \angle BAG = 59^{\circ}}[/tex]
Find DG:
[tex]DG = EG[/tex] (Perpendicular bisectors of the sides of a the triangle are equal in length from the incenter of a triangle)
Substitute[tex]\mathbf{DG = 4}[/tex]
Find BG:
[tex]BG = \sqrt{BD^2 + DG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]BG = \sqrt{11^2 + 4^2} \\\\BG = \sqrt{137} \\\\\mathbf{BG = 11.7}[/tex]
Find BE:
[tex]BE = \sqrt{BG^2 - EG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]BE = \sqrt{11.7^2 - 4^2} \\\\BE = \sqrt{120.89} \\\\\mathbf{BE = 10.99}[/tex]
Find GC:
[tex]GC = \sqrt{CF^2 + FG^2}[/tex] (Pythagorean Theorem)
Substitute[tex]GC = \sqrt{20^2 + 4^2} \\\\GC = \sqrt{416} \\\\\mathbf{GC = 20.4}[/tex]
In summary, applying the definition of the incenter of a triangle, the measures in triangle ABC where G is the incenter are:
[tex]\mathbf{m \angle ABG = 20^{\circ}}[/tex][tex]\mathbf{m \angle BCA = 22^{\circ}}[/tex][tex]\mathbf{m \angle BAC = 118^{\circ}}[/tex][tex]\mathbf{m \angle BAG = 59^{\circ}}[/tex]DG = 4BE = 10.99BG = 11.7GC = 20.4Learn more here:

Heather designed some artwork that she plans to sell. She spent $22 on supplies
and will price the artwork at 80% markup. What will be her selling price?
Answer: She should sell her artwork for $39.60 or almost $40.
Step-by-step explanation:
First you need to find out what 80% of 22 is, which is 17.6, then you add that price to the price of her supplies.
22+17.6=$39.60
In the following figure, m || QR. Then, the measure of ∠QPR is
Given:
m || QR
To find:
The measure of ∠QPR.
Solution:
Since m || QR and a transversal line intersect them, therefore the alternate interior angles are equal.
Let points S and T lie on the line m. S is on the right and T is on the left side of point P.
[tex]m\angle RPS=m\angle PRQ[/tex]
[tex]m\angle RPS=45^\circ[/tex]
Now, angles TPQ, QPR and RPS lie on the one side of a straight line. It means, their sum is 180 degrees.
[tex]m\angle TPQ+m\angle QPR+m\angle RPS=180^\circ[/tex]
[tex]50^\circ+m\angle QPR+45^\circ=180^\circ[/tex]
[tex]m\angle QPR+95^\circ=180^\circ[/tex]
[tex]m\angle QPR=180^\circ-95^\circ[/tex]
[tex]m\angle QPR=85^\circ[/tex]
Therefore, the measure of angle QPR is 85 degrees.
Johnny has 30 marbles. Mark has m marbles. If Johnny has 10 times as many marbles as Mark, write an equation that shows how many marbles Mark has.
Answer: 3
Step-by-step explanation:
From the question, we are informed that Johnny has 30 marbles while Mark has m marbles.
Since Johnny has 10 times as many marbles as Mark, it means that Johnny has: = 10 × m = 10m
Therefore, 10m = 30
m = 30/10
m = 3
Mark has 3 marbles
