To solve problems about spans of time that include B.C. and A.D. dates, you would need to use which numbers?

Mathematics

The correct numbers to use in solving problems about spans of time like B.C. and A.D. should be “integers”.

Integers are whole numbers (not a fractional number or not a decimal number) which can take a value of negative, zero, or positive number. Example of integers would be -1, 0 and 1.

<span>In calculations, the time period would be on the x-axis. Since B.C. and A.D. are two different spans of time, therefore in the calculations, the date of BC should be negative (negative x-axis) while the date of AD should be positive (positive x-axis). This would place the origin as the common reference.</span>

For #2, ∠3 and ∠1 are supplementary. You know that the measure of ∠1 is 162°, so what is ∠3? 180-162=18.
m∠3=18° if ∠1=162°.
Hope this helped!

Show that 3/5 id bigger than 5/9
SashulF [63]

Step-by-step explanation:

the common denominator for these two is 45, as you have to times 5 by 9 to get this you will have to times 3 by 9 aswell so that fraction would be 27/45.

as you have to times 9 by 5 to get 45 you will have to times 5 by 5 which is 25 so that fraction would be 25/45

3/5=27/45 5/9=25/45

27 is bigger than 25

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
Eduardwww [97]

Answer:

n = -4

Step-by-step explanation:

You must write and solve a symbolic equation.

n - 6 = 5(n + 2), or

n - 6 = 5n + 10

Combining like terms, we get:

-16 = 4n,

and so n = -4

Find the area of the figure above. use 3.14 for π. do not round your answer
professor190 [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

This is the combination of three figures semi circle, rectangle and triangle.

We will find the area of each figure and will add them.

The radius of the circle is half of the diameter, so radius is 6.

Area of semi circle will be : \frac{1}{2} \times 3.14 \times 6^2

Area of semi circle is : 56.52

Area of rectangle is: length \times width

So, area of rectangle is:40\times 12=480

Area of triangle is : \frac{1}{2}\times base\times height

So, area of triangle is :\frac{1}{2} \times 12\times 5=30

Adding all these three areas, the area of above figure will be:

[tex]Area = 56.52+480+30

Hence Area is 566.52............... Answer

Find 10th term of a geometric sequence whose first two terms are 2 and -8. Please answer!!
Shalnov [3]

Answer:

The 10th term is -524,288

Step-by-step explanation:

The general format of a geometric sequence is:

a_{n} = r*a_{n-1}

In which r is the common ratio and a_{n+1} is the previous term.

We can also use the following equation:

a_{n} = a_{1}*r^{n-1}

In which a_{1} is the first term.

The common ratio of a geometric sequence is the division of the term a_{n+1} by the term a_{n}

In this question:

a_{1} = 2, a_{2} = -8, r = \frac{-8}{2} = -4

10th term:

a_{10} = 2*(-4)^{10-1} = -524288

The 10th term is -524,288
