Answer:
360 degrees
Step-by-step explanation:
The sum of exterior angles of a heptagon is 360 degrees. For regular heptagon, the measure of the interior angle is about 128.57 degrees. The measure of the central angle of a regular heptagon is approximately 51.43 degrees. The number of diagonals in a heptagon is 14.
Answer:
Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is 
Step-by-step explanation:
Given:
point G( x₁ , y₁) ≡ ( 2 ,-3)
point D( x₂ , y₂) ≡ (2 , 4)
To Find:
Distance between GD=?
Solution:
Distance Formula between two point is given by

Substituting the values we get


Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is 
Answer:
x = 1 ⇔ y = -2.4
x = 2 ⇔ y = -1.8
x = 3 ⇔ y = -1.2
x = 4 ⇔ y = -0.6
Step-by-step explanation:

→ Rearrange to make y the subject

→ Multiply everything by -1

→ Divide everything by 5

⇒ Substitute x = 1, 2, 3 and 4

Use a ratio box to solve this problem the ratio of new pens to used pens was 4 to 7 in all there were 242 pens, how many new pens were in the box?
Answer:
88 new pens
Step-by-step explanation:
The ratio of new pens : Old pens = 4:7
Sum of Proportion = 4 + 7 = 11
Total number of pens = 242 pens
The number of new pens is calculated as:
4/11 × 242 pens
= 88 new pens
Therefore, the number of new pens = 88 new pens
