Answer:
seventh interior angle=∠x=29°
Step-by-step explanation:
sum of interior angle of polygon is equal to 360°
let seventh angle of heptagon is x
∠x+47°+55°+62°+64°+54°+49°=360°
∠x=360°-(47°+55°+62°+64°+54°+49°)
∠x=360°-331°=29°
∠x=29°
seventh interior angle=∠x=29° answer
Increase.
1/4 can be translated to 25%
1/2 can be translated to 50%
25% to 50% is an increase.
Answer:
3 is yes, the rest is no
Step-by-step explanation:
for y = -6x - 9
(1) if x = 7, y = -51 => No
(2) if x = 3, y = -27 => No
(3) if x = -8, y = 39 => Yes
(4) if x = -5, y = 21 => No
For the first one it’s b and I’m sorry but I’m not sure about the second
Lan is 146 centimeters tall now.
<u><em>Explanation</em></u>
Let, Lan's current height is centimeters
As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = centimeters and Jim's current height = centimeters.
Every month, their heights increase by 2 centimeters.
So, after 5 months.....
Lan's height = centimeters,
Lisa's height = centimeters and
Jim's height = centimeters
Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....
So, the current height of Lan is 146 centimeters.
