Answer:
10th term of the sequence 64,16,4... = 1/4096
Step-by-step explanation:
Points to remember
nth term of GP is given by.
Tₙ = ar⁽ⁿ⁻¹⁾
Where r is the common ratio and a is the first term
<u>To find the 10th term of given GP</u>
It is given that,
64, 16, 4,......
a = 64 and 6 = 1/4 Here
T₁₀ = ar⁽ⁿ⁻¹⁾
= 64 * (1/4)⁽¹⁰⁻¹⁾ = 64 * (1/4⁹)
= 4³/4⁹ = 1/4⁶ = 1/4096
2 triangle+square=23
square=60/triangle
2 triangle+60/triangle=23
2 triangle^2+60=23 triangle
2 triangle^2-23 triangle+60=0
solving quadratic equation we get
triangle=15/2 , 4
15/2 is not possible so triangle=4
square=15
Answer:
112 ft square
Step-by-step explanation:
Perimeter=2l+2w
l=w+6
Perimeter=2(w+6)+2w
44=2w+12+2w
44=4w+12
32=4w
8=w
l=8+6
l=14
area=lw
area=14x8
area=112 ft square
30-5*4+2
30-20+2
10+2
12 is the answer
Answer:32
Step-by-step explanation:just divided both sides by 12 that will be 348:960=32:80
