Answer:

18cm

Step-by-step explanation:

We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.

a = l * w

20 = 5 * w

divide both sides by 5 to cancel the multiplication by 5 on the right side

4 = w

The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.

p = 2l + 2w

p = (2 * 5) + (2 * 4)

p = 18

What is <br> 10 more than 36

nikitadnepr [17]

Hi there!

Pretty much, more means to add, so when you said, "10 more than 36", we immediately think addition. :)

36 + 10 = 46, right?

So, your answer is 46 :)

Hope this helps!

Message me if you need anything else, I'd be happy to answer any other questions you may have!

avanturin [10]

Answer:

Option 2: 1.5 is the correct answer.

Step-by-step explanation:

Given information is:

Mean = μ = $27

SD = σ = $5.50

A z-score simply tells us how far a selected data value from the mean is.

Z-score is denoted by z and is given by the formula:

$z = \frac{x-mean}{SD}$

Let x = $35.25

Putting the values of mean and SD we get,

$z = \frac{35.25-27}{5.50}\\z = \frac{8.25}{5.50}\\z =1.5$

The value of z-score for a price of $35.25 per barrel is 1.5

Hence,

Option 2: 1.5 is the correct answer.

Valuate the xpression 4(10-4) power of 2 devided by 4

liq [111]

Hence, the value of the expression is 36.

Solution:

Step 1: Given expression is $4(10-4)^{2} \div 4$ .

BODMAS means do Bracket, Of, Division, Multiplication, Addition, Subtraction

Step 2: Using BODMAS rule first simplify the expression which is in bracket.

⇒ $4(10-4)^{2} \div 4=4(6)^2\div4$

Step 3: Squaring of the number 6.

⇒ $4(6)^2\div4=4\times36\div4$

Step 4: Using BODMAS rule, divide 36 by 4.

⇒ $4\times36\div4=4\times9$

Step 5: Using BODMAS rule, multiply 4 with 9.

⇒ $4\times9=36$

Hence, the value of the expression is 36.
