Answer:
D) 35, 38, 41, 44, 47, 50,...
Step-by-step explanation:
The general term of an arithmetic sequence is
, where n ∈N and n ≥ 1.
When n=1,
When n=2,
When n=3,
When n=4,
When n=5,
When n=6,
Hence the sequence is 35, 38, 41, 44, 47, 50,...
The correct answer is D
Answer: use formulas for area of square/triangle
Step-by-step explanation:
1st one is a rhombus so use A= BH
which is 5x4 = 20
2nd one is a kite
i assume you have not learnt the formula for kites so u can use triangles (A=1/2BH)
triangle CBA: 1/2 x (6+6)(2) = 12
triangle ACD: 1/2 x (6+6)(10)= 60
area = 12 + 60 = 72
QUESTION:
A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent full. how fast did the battery charge and how long did it take?
Solution :
<u>Given</u>
- Initial amount of charge = 23%
- Amount after charge = 89%
<u>procedu</u><u>re</u>
Let the rate of charging be r .
r = (change in charge level) / (time interval) = (89% - 23%) / (30 min) = 2.2 % per minute
charge = (rate of charging)(time) + (initial charge)
100% = r*t + 23%
100% = (2.2 %/min)t + 23%
Solve for t and get
t = [(100 - 23) / 2.2]
Answer = 35 min

Answer:
C(-4,-2), D(3,-7)
Step-by-step explanation:
we procced to identify points:
A(-4,-7), B(3,-2)
for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)
C(-4,-2), D(3,-7); Area of the rectangle Ar=b*h, where
So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=
