Calculate 28×13 and use roman numerals to write the equation and answer

The list shows numbers in order from least to greatest. Negative 34, negative 2 and three-fourths, blank, negative 1.5, 0, 2.3,

blsea [12.9K]

Options

-2.5
-2
$-1\dfrac{9}{10}$
-1

Answer:

(B) -2

Step-by-step explanation:

Given the list

$-34.-2\dfrac{3}{4} ,x, -1.5,0,2.3,10,25\dfrac15$

This list has been arranged in order from the least to the greatest.

We are required to find an Integer that can be inserted on the blank line (I have used x) in the list.

An integer is defined as a positive or negative whole number.

Out of the given options, only -1 and -2 are integers. However:

-1 is greater than -1.5

Therefore, it cannot be our result.

The correct answer is -2.

A chair’s regular price is $349. It is on clearance for 30% off, and a costumer uses a 15% of coupon after that. What is the fin

makkiz [27]

Answer:

The final cost is $207.65

Step-by-step explanation:

Regular price of the chair is $349

with 30% off,

(30/100)*$349 = 0.3*$349

= $104.70

actual cost is $349 - $104.70 = $244.30

For a customer using 15% off coupon

15% of actual cost

(15/100)*244.30 = 0.15*244.3

= $36.65

Final cost is $244.30 - $36.65

= $207. 65

How do i round 186.282?

adoni [48]

Well, first you need to decide what place you want to round it TO.

Example: Round it to the nearest hundredth:

The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .

-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .

Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.

I'm curious . . . where did this number come from ?

It happens to be one thousandth of the speed of light, in miles per hour.

Did it come up in science class, or did a science geek use it for
one of the problems in math ?

Which summation formula represents the series below? 13 + 9 + 5 + 1

Ket [755]

Answer:

The summation formula for the series is ⇒ 15n - 2n²

Step-by-step explanation:

* Lets check the series 13 , 9 , 5 , 1

∵ 9 - 13 = -4

∵ 5 - 9 = -4

∵ 1 - 5 = -4

∴ The series has a common difference

∴ It is an arithmetic series with first term a and constant difference d

* That means

- a1 = a , a2 = a + d , a3 = a + 2d , a4 = a + 3d

∴ an = a + (n - 1)d, where n is the position of the number in the series

* The sum of the arithmetic series can find by the rule

- Sn = n/2[2a + (n - 1)d], where n is the number of terms you want to add

* Lets use this rule in our problem

∵ Sn = n/2[2(13) + (n - 1)(-4)]

∴ Sn = n/2(26 + (-4n + 4)] ⇒ open the small bracket

∴ Sn = n/2[26 - 4n + 4] ⇒collect the like terms

∴ Sn = n/2[30 - 4n] ⇒ open the bracket

∴ Sn = (n/2)(30) - (n/2)(4n)

∴ Sn = 15n - 2n²

* The summation formula for the series is 15n - 2n²
