Answer:
TRUE
Step-by-step explanation:
TRUE
a_1 = 2
a_n = 2*(an_1)
if we start with 2, we would get
a_2 = 2*(a_1) = 2*(2) = 4
a_3 = 2*(a_2) = 2*(4) = 8
a_4 = 2*(a_3) = 2*(8) = 16
a_5 = 2*(a_4) = 2*(16) = 32

Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dollars.

Answer:
B) 10 m
Step-by-step explanation:
Area is 20 and Height is 4
Ok so
AREA of a triangle is =1/2Base Times Height
work back
Area=20
Height=4
b=Base
20=1/2b*4
Simplify both sides of the equation.
20=2b
Flip equation
2b=20
Divide both sides by 2
b=10
Base=10 m
