Answer: 7 gallons decrease per minute
Step-by-step explanation:
56 gallons / 8 minutes = 7 gallons per minute
to make sure do it backwards: 7 gallons x 8 minutes = 56 gallons :)
Answer:
a) ∠a = 72°
∠b = 108°
b) ∠ = 56°
c) ∠m = 95°
Step-by-step explanation:
- Sum of interior angles of a polygon = (n − 2) × 180
(where n is the number of sides)
- If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.
The sum of the exterior angles of a polygon = 360°
- The sum of angles on a straight line = 180°
a) This shape is a regular polygon with 5 sides.
Therefore, sum of the interior angles = (5 - 2) x 180 = 540°
Therefore, ∠b = 540 ÷ 5 = 108°
∠a = 180 - 108 = 72°
b) The sum of the exterior angles of a polygon = 360°
Therefore, 55 + 63 + 52 + 44 + 90 + = 360
304 + = 360
= 360 - 304 = 56°
c) The sum of the exterior angles of a polygon = 360°
Therefore, 40 + 40 + 35 + 40 + 50 + 60 + m = 360
265 + m = 360
m = 360 - 265 = 95
Normally you would put the numbers least to greatest and the number in the middle would be the median.
But in this case 2 numbers, 2.99 and 3.89 are in the middle.
In this case the mean of the two middle numbers is the median.
3.44
Answer:
false
Step-by-step explanation:
I would assume false as if each of the fours sides of the square are 5 cm, then doing the equation 5×4 (unsing 4 for the each of the congruent sides) would give up 20 cm.
We have to calculate the area of the polygon. This polygon is made of a parallelogram and the right triangle. The area of the triangle: A 1 = a * b / 2 = 8 * 17 / 2 = 136 / 2 = 68 cm^2. The area of a parallelogram : A 2 = a * h = 17 * 6 = 102 cm^2. Finally: A ( polygon ) = A 1 + A 2 = 68 + 102 = 170. Answer: B. 170 cm^2.<span> </span>
