Answer: 11.4

Step-by-step explanation:

Okay so we are going to use PEMDAS,

So first we multiply 2 times 5 first and get 10

(9-84 divided by 10 + 5+6)+2

(9-8.4+5+6)+2

( 9- 8.4 + 11) +2

( -1.6 + 11) +2

9.4 + 2

11.4

Two students have different ways to calculate (0.25)⋅(0.044) as a decimal. Show, in detail, how each student might compute this

Ulleksa [173]

Answer:

(0.25)⋅(0.044) = 0.011

Step-by-step explanation:

Two students have different ways to calculate (0.25)⋅(0.044) as a decimal.

Show, in detail, how each student might compute this product. (upload your work when complete)

We are given:

(0.25)⋅(0.044)

= 0.25 × 0.044

a) For Elena

Elena says, "I find 25⋅ 4.4 and then move the decimal point."

What Elena did was she multiplied both

number by 100

= (0.25 × 100) × (0.044 × 100)

We add up the decimal points from 0.25 and 0.044 = 5

Hence, the answer we get in step 1 is divided by 100000 in other it move the brackets

(0.25 × 100) × (0.044 × 100)/100000

= 0.011

b) For Diego

Diego says, "0.25 is the same as 1/4, so I found 1/4 of 0.044."

Diego converted 0.25 to fraction

= 0.25 × 100/100

= 25/100 = 1/4

Since, (0.25)⋅(0.044)

= 0.25 × 0.044

Then:

1/4 of 0.044

= 1/4 × 0.044

= 0.011

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t

olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

$an = a + d(n - 1)$

$let \: a = 200,d = - 10$

$an = 200 - 10(n - 1)$

$an = 200 - 10n + 10$

$an = - 10n + 210$

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

$let \:n = 20$

$20th \: term = - 10(20) + 210$

$20th \: term = - 200 + 210$

$20th \: term = 10$

What’s the distance between (4,-9) and (5,3)

laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

Given formula

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute values into the formula

$Distance = \sqrt{(5-4)^2+(3+9)^2}$

Simplify values in the parentheses

$Distance = \sqrt{(1)^2+(12)^2}$

Simplify exponents

$Distance = \sqrt{1+144}$

Simplify by addition

$Distance = \sqrt{145}$

Hope this helps!! :)
