Answer:
-2
Step-by-step explanation:
(3×2²⁰-5×2¹⁹)/(-2⁶)³
=[(3×2-5)×2¹⁹]/-(2⁶)³
=[(6-5)×2¹⁹]/-2¹⁸
=1×(-2)
=-2
Answer:
615 centimeters
Step-by-step explanation:
Kate used 6.15 meters of ribbon to make a bow
The centimeters of the ribbon used by kate can be calculated as follows
1 meter=100 centimeters
6.15 meters= x
Cross multiply both sides
1 × x = 6.15 × 100
x = 615 centimeters
Hence Kate used 615 centimeters of the ribbon

Answer:
67
Step-by-step explanation:
From the question given above, the following data were obtained:
Number of terms (n) = 12
Last term (L) = 100
Common difference (d) = 3
First term (a) =?
We can obtain the first term of the arithmetic sequence as follow:
L = a + (n – 1)d
100 = a + (12 – 1)3
100 = a + (11)3
100 = a + 33
Collect like terms
100 – 33 = a
a = 67
Therefore, the first term of the arithmetic sequence is 67
