Mathematics
1 answer:
ololo11 [35]3 years ago
4 0

Step-by-step explanation:

t8 = a1 + (n - 1)*d

t8 = 17

17 = a1 + 7*d

t12 = 25

25 = a1 + 11d

17 = a1 + 7d Subtract

8 = 4d Divide by 4

8/4 = 4d/4

2 = d

17 = a1 + 7d

17 = a1 + 7*2

17 = a1 + 14 Subtract 14

3 = a1

Sum 20 terms

The 20 term = a1 + 19*2

The 20 term = 3 + 38

= 41

Sum = (a1 + a20) * 20 / 2

Sum = (3 + 41)* 20/2

Sum = 44 * 10

Sum = 440

-Dominant- [34]

Answer:

The maximum number of miles they can travel is 6 miles.

Step-by-step explanation:

Because of the fix charge of $2, the amount of money left for the rest of the trip is $18. In order to find how many miles $18 cover when the cab charges $3 per hour, 18 is divided by 3. 18/3=6.

Tan²( θ ) - (1 + √3) tan (θ) + √3 = 0

tan²( θ ) - (tan (θ) + √3 tan (θ)) + √3 = 0

tan²( θ ) - tan (θ) - √3 tan (θ) + √3 = 0

tan( θ ) ( tan (θ) - 1) - √3 ( tan (θ) - 1 ) = 0

( tan( θ ) - 1 ) ( tan( θ ) - √3 ) = 0


tan( θ ) - 1 = 0

θ = π/₄

tan( θ ) - √3 = 0


θ = π/₃


so θ = π/₄ and θ = π/₃

How many integers from 1 through 100 are neither multiples of 2 nor multiples of 3 ?
julia-pushkina [17]
----------------------------------------------------------------------------
Find total number of integers
----------------------------------------------------------------------------
Number of integers from 1 to 100 = 100
There are 100 numbers altogether

----------------------------------------------------------------------------
Find total numbers that can be divided by 2
----------------------------------------------------------------------------
Number that are multiples of 2 = 100 ÷ 2 = 50
50 of the number are multiples of  2

----------------------------------------------------------------------------
Find total numbers that are multiples of 3
----------------------------------------------------------------------------
Numbers that are multiples of 3 = 100 ÷ 3 = 33 R 1
33 of the numbers are multiples of 3

Of the 33 numbers that are multiples of 3, half of the numbers are even and had been included in multiples of 2.
33 ÷ 2 = 16 R 1

33 - 16 = 17
17 of the numbers are multiples of 3

----------------------------------------------------------------------------
Total numbers that can be multiples of 2 or 3
----------------------------------------------------------------------------
50 + 17 = 67

----------------------------------------------------------------------------
Total number that are neither multiples of 2 nor 3
----------------------------------------------------------------------------
100 - 67 = 33

----------------------------------------------------------------------------
Ans: 33 integers are neither multiples of 2 nor multiples  3
