Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°
Answer:
(a+2)
Soo you could solve by removing the parenthesis, then combining all like terms. Then subtract.
Answer:
<h3>21 RASBERRIES</h3>
Step-by-step explanation:
THERE ARE 147 STRAWBERRIES.
THE RATIO OF RASBERRIES TO STRAWBERRIES ARE 1:7
THEN,
THE AMOUNT OF RASBERRIES ARE 1/7 TIMES OF THE STRAWBERRIES.
SO,THERE ARE (147×1/7) or,21 RASBERRIES.
SO THE ANSWER IS: THERE ARE 21 RASBERRIES...
Answer:
See below in bold.
Step-by-step explanation:
a. The factor of growth = 1.08 per year so
P = 20(1.08)^t where P = the bear population and t = the time in years since 2010.
b. It is 10 years after 2010 so:
In 2020: P = 20 * (1.08)^10
= 43 bears.
c. When P = 100 we have:
100 = 20 * (1.08)^t
(1.08)^t = 100/20 = 5
t ln 1.08 = ln 5
t = 20.9 years.
So there will be more than 100 bears in the year 2010 + 21
= 2031.
