Answer:
6a−14
Step-by-step explanation:
Answer:
2:3
Step-by-step explanation:
A total of 30 students with 12 girls so its 12/30 & its the balance of 18 boys or 18/30
12:18 ÷ by 2 on both sides is.6:9 & 2:3, Answer is Ratio of 2:3.
Answer:
<h2>The circumference is multipled by 4.</h2>
Step-by-step explanation:
The formula of an area of a circle"

The formula of a circumference of a circle:

The area multipled by 16:

The radius has increased fourfold, therefore:

The circumference is multipled by 4.
You can calculate the area and check the circumference:

Calculate the radius:
<em>divide both sides by π</em>

Calculate the circumference of both circles:



John's function : y = 3.5x - 4
Penny's function : y = 3x + 4
C. John's function has a greater rate of change, because 3.5 > 3
See the attached figure.
m ∠KAJ = 170° & m ∠LAM = 80°
We should know that :
m ∠KAJ + m ∠LAM + m ∠KAL + m ∠MAJ = 360°
∴ m ∠KAL + m ∠MAJ = 360° - (m ∠KAJ + m ∠LAM)
∴ m ∠KAL + m ∠MAJ = 360° - (170°+80°) = 360° - 250° = 110°
But : m ∠KAL = m ∠MAJ ⇒⇒⇒ <u>Opposite angles.</u>
∴ m ∠MAJ + m ∠MAJ = 110°
∴ 2 * m ∠MAJ = 110°
∴ m ∠MAJ = 110° ÷ 2 = 55°
<u>So, the answer is : m ∠MAJ = 55°</u>
