Answers

Answer:

D

Step-by-step explanation:

The value of digits are

9- Ten thousand, 4- Hundred and 6- Ones.

What is Place value?

In mathematics, place value refers to the relative importance of each digit in a number. These locations begin at the unit's location (ones place). The place values of a number's digits are expressed in the following order: ones/units, tens, hundreds, thousands, ten thousands, and so on.

The value of each digit in a number is known as place value. Every digit in a number has a distinct value depending on where it is located.

We have the number 90, 406.

Now, the place value of each digit in the given number is:

9- Ten thousand

0- Thousand

4- Hundred

0- Tens

6- Ones.

So, 9- Ten thousand, 4- Hundred and 6- Ones.

Complete the following sentence

If x is to 6 as 10 is to 15, then x is equal to .

Answers

Answer:

x=4

Step-by-step explanation:

x/6 = 10/15

x/6 = 2/3

3x=12

Answer:

x=4

Step-by-step explanation:

To find this, you must first figure out the relationship between 10 and 15. Since 10 is 2/3 of 15, "x" must be 2/3 of 6.

To find "x", divide 6 by 3 to get 2, then 2 by 2 to get 2/3 of 6 (4). Thus meaning X = 4.

Find the common ratio and the three terms in the sequence after the last one given. -4, 16, -64, 256, …

Answers

Answer:

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

The next three terms after the last one will be:

[tex]a_5=-1024[/tex][tex]a_6=4096[/tex][tex]a_7=-16384[/tex]

Step-by-step explanation:

Given the sequence

-4, 16, -64, 256, …

Finding the common ratio

An arithmetic sequence has a constant ratio 'r' and is defined by  

[tex]a_n=a_1\cdot r^{n-1}[/tex]

computing the ratios of all the adjacent terms

[tex]\frac{16}{-4}=-4,\:\quad \frac{-64}{16}=-4,\:\quad \frac{256}{-64}=-4[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

Finding the next three terms

Given the sequence

-4, 16, -64, 256, …

here

[tex]a_1=-4[/tex]

[tex]r=-4[/tex]

substituting [tex]a_1=-4[/tex] and [tex]r=-4[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=-4\left(-4\right)^{n-1}[/tex]

substituting n = 5 to determine the 5th term

[tex]a_5=-4\left(-4\right)^{5-1}[/tex]

[tex]a_5=-4^4\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_5=-4^{1+4}[/tex]

[tex]a_5=-4^5[/tex]

[tex]a_5=-1024[/tex]

substituting n = 6 to determine the 6th term

[tex]a_6=-4\left(-4\right)^{6-1}[/tex]

[tex]a_6=-4\left(-4^5\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]a_6=4\cdot \:4^5[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_6=4^{1+5}[/tex]

[tex]a_6=4^6[/tex]

[tex]a_6=4096[/tex]

substituting n = 7 to determine the 6th term

[tex]a_7=-4\left(-4\right)^{7-1}[/tex]

[tex]a_7=-4^6\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_7=-4^{1+6}[/tex]

[tex]a_7=-4^7[/tex]

[tex]a_7=-16384[/tex]

Therefore, the next three terms after the last one will be:

[tex]a_5=-1024[/tex][tex]a_6=4096[/tex][tex]a_7=-16384[/tex]

Evaluate the expression 53 ÷ (13 − 8) × 2.

Answers

the correct answer would be about 11.923

Answer:

im confused too so lets work together!

Step-by-step explanation:

(13 - 8 = 5.) so, rewrite the problem as 5 cubed divided by (5) x 2! Now, we figure out 5 cubed. 5 x 5 equals 25, x 5 equals 125. So, 125 divided by 5 would be 25. Now, 25 x 2 is 50.

The final answer would be 50!

<AOP + < BOP = 180°< being linear pair >

x + 30° + x - 30° = 180°

2x = 180°

x = 90°

Now

<AOP = x + 30° = 90° + 30° = 120°

<BOP = x - 30° = 90° - 30° = 60°

<AOP is obtuse angle because it is less than 180° but more than 90°.<BOP is acute angle because it is less than 90°.
