The question is corrected to get;

405,852

Step-by-step explanation:

The expression of the description when written as follows;

'I am a 6-digit number one of my 4s is worth 400,000. The other 5 is worth 1/100 as much. My 5 is worth 5 (10s). y 8 is worth 800. My 2 is' worth 2. My other digit is a 0 what number am I, we have;

The number of digits in the number = 6

The position of the number 4 = 100,000s, we have;

4xx,xxx

The position of the number 5 is in the 10s position, we have;

4xx,x5x

The other 5 = 50100 = 0.5

Therefore, we have;

4xx,x5x.5

The position of the 8 is the 100s, to give;

4xx,85x.5

The number 2 is in the unit position, therefore, we have;

Answer:

184

Step-by-step explanation:

here's your solution

=> first term = 4 = a

=> common difference = 2 = d

=> formula = a + (n - 1) d

=> putting the value of variable

=> 4 + (91 - 1)* 2

=> 4 + (90 * 2)

=> 4 + 180

=> 184

If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything

Step-by-step explanation:

This triangle is equilateral

Then

[tex]db = \frac{1}{2} ab = .5 \times 12 = 6 [/tex]

By using the phythgorth thearm you can find CD

[tex]cd = \sqrt{ {ab}^{2} - {db}^{2} } \\ = \sqrt{144 - 36} = 6 \sqrt{3} [/tex]

Then the eara of triangle is

[tex] \frac{1}{2} \times 6 \times 6 \sqrt{3} = 18 \sqrt{3} [/tex]

Step-by-step explanation:

Hello There!

First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)

Because the fee is 3 dollars we can immediately eliminate answers B and C

Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)

Once again we want to choose two points on the line and plug it in into the slope formula

the points are optional but i have chosen the points (1,4.5) and (2,6)

*plug it into the slope formula*

[tex]slope=\frac{6-4.5}{2-1} \\6-4.5=1.5\\2-1=1\\slope =\frac{1.5}{1} or1.5[/tex]

so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A  

Answer:

36

Step-by-step explanation:

devide 105 by 3 then add one 34+35+36=105

Answer:

It's 37 because the three are 33, 35, and 37. 37 is the largest of all of them.

Step-by-step explanation:

105/3 = 35, therefore the middle number is 35, and the 3 numbers are 33, 35, and 37.

Answer:

2 2/5

Step-by-step explanation:

It is because the 2 wholes and 2/5

Answer:

2 and 2/5

Step-by-step explanation:

Because the first two pies are completely shaded giving us the 2 whole. And the third pie has two parts shaded out of the five parts giving us the 2/5.

Now you put them together: 2 and 2/5.

Answer: 6.5

Step-by-step explanation:

1 (to the power of 5) is 1 and 5 (to the power of 2) is 25.

25 (to the power of 0) is 1 and 5 (to the power of 1) is 5.

1 + 25 = 26 and 1 - 5 = -4.

Since the slash means division in math and any number to the power of 0 is always 1.

The answer would be: -6.5.

The solution for the expression  [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex] after simplifying is,

[tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)} = \frac{- 13}{2}[/tex]

We have to give that,

The expression to simplify is,

⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]

Simplify the expression by simplifying each term in a given fraction,

⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]

Since,

1⁵ = 1

5² = 5 × 5

= 25

25⁰ = 25

5¹ = 5

Substitute all the values,

⇒ [tex]\frac{(1 + 25)}{(1 - 5)}[/tex]

⇒ [tex]\frac{26}{-4}[/tex]

⇒ [tex]\frac{-26}{4}[/tex]

Simplify the fraction in simplest form,

⇒ [tex]\frac{- 13}{2}[/tex]

Hence, The solution is, - 13/2

Answer:

16 9/20 years old

Step-by-step explanation:

Leo is 13 3/ 4 years old.

Step 1

Sheila is 1 1 /2 years older than Leo

Sheila = 13 3/4 years + 1 1/2 years

13 + 1 + ( 3/4 + 1/2)

Lowest common denominator 4

14 + ( 3 + 2/4)

14 + 5/4

= 14 + 1 1/4

= 15 1/4 years old

Jane is 1 1/ 5 years older than Sheila.

Jane's age = 15 1/4 years old + 1 1/5 years

15 + 1 + (1/4 + 1/5)

Lowest common denominator = 20

16 + (5 + 4/20)

16 9/20 years old

Therefore, Jane is 16 9/20 years old
