Answer:
x = 25
Step-by-step explanation:
The interior angle adjacent to the 123° angle is supplementary to it.
Its measure is 180° - 123° = 57°
The sum of the measures of the interior angles of a polygon is
(n - 2)180° = (4 - 2)180° = 2(180°) = 360°
3x + 7 + 96 + 5x + 57 = 360
8x + 160 = 360
8x = 200
x = 25
62 rows of 9 chairs.
The questions asks about how many, so we are estimating. So we will round 62 down to 60 and 9 up to 10.
So, 60 rows of 10 chairs.
Then we multiply 60 * 10 to get 600.
The exact amount of 62*9 = 558, but we are estimated so our estimation would be there are about 600 chairs.
3 yards per second is 9 feet per second, which is 9*60*60=32400 feet per hour. This is 32400/5280=6.14 miles per hour.
Answer:
40 cm squared
Step-by-step explanation:
Area = length * width
10*4cm = 40 cm squared
This is a true statement, or false depending on whether Alfonso actually did or not. There's no proof.
