The true statements about Marcus graph are:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
<h3>How to determine the true statement</h3>
From the complete question, we have the following parameters:
<u>Phone service 1</u>
- Initial cost: $40
- Rate: $8.50 per service
<u>Phone service 2</u>
- Initial cost: $30
- Rate: $10.50 per service
By comparing the above parameters:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
The above statements represent the true statements about the Marcus' graph

Paula needs a total of 1.47 meters of ribbon to cover the entire perimeter of her painting.
Each piece of ribbon is 25 centimeters long.
To find how many pieces Paula needs, convert the meters to centimeters and divide.
1.47 meters = 147 centimeters
Paula needs 147 centimeters of ribbon.
Divided 147 by 25 to find how many 25 cm long pieces of ribbon Paula needs.
147 / 25 = 5.88
Paula needs 5.88 pieces of ribbon.
Since you can't buy just 0.88 piece of a ribbon, you need to buy a full one and just be left with some leftovers, like remainders.
This means Paula needs 6 ribbon pieces.
Hope this helps!
x^2 -3x+11=0
using the determinant

(-3)^2 -4(1)*11
9 -44
-36<0 it has no real solutions
Answer:
Given - Two angles measures 2x and 3x
To find - size of 3x
Solution -
2x + 3x = 360° ( Make reflex angle )
5x = 360°
x = 360/5
x = 72°
3x = 3 * 72 = 216°
Answer:
h = a * sin α
Step-by-step explanation:
The easiest answer is utilizing Law of Sines: a / Sin A = b / Sin B = c /Sin C
a and ∠α : known
∠AEB = 90°
a / Sin 90° = h / Sin α .. Sin 90° = 1
h = a * sin α
