Answer:
120
Step-by-step explanation:
Make a chart:
Lines: 0 1 2 3 4 5 6
Closed regions: 0 0 0 1 3 6 10
Find the number of numbers using the formula:
[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14
= 8.5 x 14
= 119
119 + 1 = 120
(add 1 because we didn't count the first line in the formula)
I hope this helps :)
The total number of closed regions is 120.
Given that,
Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.
Used the formula to calculate the number of closed regions with n sides is,
Number of sides = (n - 1) (n - 2) / 2
Here, n = 17
Hence, The number of closed regions is,
Number of sides = (n - 1) (n - 2) / 2
Number of sides = (17 - 1) (17 - 2) / 2
Number of sides = 16 × 15 / 2
Number of sides = 120

Find the value of x.
A) 870
C) 127°
E) 66°
B) 106°
D) 100°
Answer:
100
Step-by-step explanation:
y + 140 = 180 {Linear pair}
y = 180 - 140
y = 40
Given triangle is an isosceles triangle.
x + y + y = 180 {angle sum property of triangle}
x +2y = 180
x +2*40 = 180
x + 80 = 180
x = 180 - 80
x = 100

What expressions is equivalent to 5 to the power of 8
Answer:
Step-by-step explanation:
5¹⁶ ÷ 5² = 5⁽¹⁶ ⁻ ²⁾ = 5¹⁴ ❌
(5²)⁶ ÷ 5⁴ = 5⁽¹² ⁻⁴⁾ = 5⁸ ✅
5² × 5⁴ = 5⁽²⁺⁴⁾ = 5⁶ ❌
(5⁴)² = 5⁸ ✅
5⁻¹ × 5⁹ = 5⁻¹ ⁺ ⁹ = 5⁸ ✅
5⁻¹ × 5⁻⁸ = 5⁻¹ ⁺ ⁽⁻⁸⁾ = 5⁻⁹ ❌

Three times a number increased by 44 is the same as the opposite of the number. Find the number
Answer:
- 11
Step-by-step explanation:
let the number be n then 3 times the number is 3n and the opposite is - n
3n + 44 = - n ( add n to both sides )
4n + 44 = 0 ( subtract 44 from both sides )
4n = - 44 ( divide both sides by 4 )
n = - 11
The required number is - 11

Santiago and some friends are going to the movies. At the theater, they sell a bag of popcorn for $5.75 and a drink for $3.50. How much would it cost if they bought 4 bags of popcorn and 8 drinks? How much would it cost if they bought pp bags of popcorn and dd drinks?
Answer:
$23 for popcorns and $28 for drinks the sum is $51
Step-by-step explanation:
The total cost of buying 4 bags of popcorn and 8 drinks is $51.
What is the meaning of the term “cost”?A cost is the worth of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting.
In the case of an acquisition cost, the money spent on the acquisition is considered the cost. All costs associated with obtaining and preparing materials for sale are referred to as "Cost of Purchase," or “Cost of buying,” respectively.
As per the available information,
Selling price of a single popcorn bag is $5.75.
Selling price of a single drink is $3.50.
Value or total amount of cost will be calculated against 4 bags of popcorn and 8 drinks.
Cost of popcorns = 4 × 5.75 = 23
Cost of drinks = 8 × 3.50 = 28
23 + 28 = 51
Therefore, total cost of buying 4 bags of popcorn and 8 drinks is $23 for popcorns and $28 for drinks, the sum is $51

How can I solve 8.5 x (-4)?
Answer:
-34
Step-by-step explanation:
you would first solve it like a normal equation and ignore the negative;
0.5 * 4 is 2
8 * 4 is 32
32 + 2 = 34
and then you would add the negative sign- because there is only one side with a negative sign, it is negative
if the equation had both sides had a negative, it would be positive
