Answer:
Statements 1,4&5
Step-by-step explanation:
A hole is when both, numerator and denominator, of a fraction become 0 (zero).
This would happen when the numerator and denominator have a common factor.
Example:
(2x+4)/(x+2)
= [2(x+2)]/(x+2) = 2
Although the fraction can be simplified, there's a hole at x = -2.
x = -2 will not be part of the domain.
The hole is represented by an open circle.
Answer:
3/4
Step-by-step explanation:
.74(75%) is equal to 75/100
The greatest common factor is 25, so divide 75 by 25 and 100 by 25.
75/25=3 100/25=4
So, 75/100 simplified is 3/4.
Answer: x = 15
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides.
sum of angles = (n - 2) × 180
sum of angles = (7 - 2) × 180
sum of angles = 5 × 180
sum of angles = 900°
Now to find the value of x, we have to set each of the interior angles, added up, equal to 900°:
7x + 1 + 10x + 6x + 7 + 10x - 9 + 9x + 4 + 8x + 10 + 9x + 2 = 900
Combine like terms:
(7x + 10x + 6x + 10x + 9x + 8x + 9x) + (1 + 7 - 9 + 4 + 10 + 2) = 900
59x + 15 = 900
59x + 15 - 15 = 900 - 15 subtract 15 from both sides
59x = 885
59x/59 = 885/59 divide by 59 on both sides
x = 15
Answer:
6
Step-by-step explanation:
38/7=5.42
round the 5.42 to 6
