Answer:
x = 7
Step-by-step explanation:
The sum of interior angles is equal to 360°
9x - 4 + 8x + 2 + 13x + 30 + 19x - 11 = 360° add like terms
49x + 17 = 360 subtract 17 from both sides
49x = 343 divide both sides by 49
x = 7
replace x with the value we found to calculate each angle.
360 - because a right angle is 90° and there are 4 right angles in a circle , 90 x 4 = 360
Rearrange the numbers in order from least to greatest:
<span>6, 1, 5, 2, 6, 5, 2, 6, 5
1, 2, 2, 5, 5, 5, 6, 6, 6
The number 1 is used once. The number 2 is used twice. Numbers 5 and 6 are used three times.
The mode is the number that is represented most in a set of numbers. Since 5 and 6 are both represented three times, these numbers will be the mode for this set.
The answers are C. 5 and D. 6.</span>
Ok so pete lays 10 more than jim per hour
pete and jim laid same amount of tiles
j=jim's rate
p=pete's rate
6j=5p
but pete lays 10 tile per hour faster so
p=10+j
sub
6j=5(10+j)
6j=50+5j
minus 5j both sides
j=50
jim can lay at 50 tiles per hour
The square's diagonal is the triangle's hypotenuse.
The Pythagorean theorem is = 
Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.
As the side is given 12 inches, so this becomes
inches
