Answer:

2.25

Step-by-step explanation:

Because if you do 8/6 you get 1.33333333333 so you would need to do 3/1.33333333333 and you would get 2.25.

Answer:

x = 2.25

Step-by-step explanation:

Since this is simply a reduction of a figure, we can assume the ratio is constant. With this in mind, we can set up the following proportion to solve for x.

8 / 3 = 6 / x

8 * x / 3 = 6

8 * x = 6 * 3

x = 6 * 3 / 8

x = 18 / 8

x = 9 / 4 = 2.25

Cheers.

Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (–

polet [3.4K]

The expression (21 + 5i) + (-1 + i) demonstrates the commutative property of addition for (-1 + i) + (21 + 5i)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Given the expression:

(-1 + i) + (21 + 5i)

Using the commutative property of addition, we get:

(21 + 5i) + (-1 + i)

The expression (21 + 5i) + (-1 + i) demonstrates the commutative property of addition for (-1 + i) + (21 + 5i)

Evaluate the following when a= 1 ,b=3,and c =27 ( a) 6a^2+ 2bc-2c^1/3

Dennis_Churaev [7]

Answer:

6a^2+ 2bc-2c^1/3 <u>= 162</u>

Step-by-step explanation:

a = 1
b = 3
c = 27

$\rm 6 {a}^{2} + 2bc - 2 {c}^{ \frac{1}{3} }$

$= 6 {(1)}^{2} + 2(3)(27) - 2( {27)}^{ \frac{1}{3} }$

$\rm = 6 + 162 - 2 ( \sqrt[3]{27} )$

$\rm = 168 - 2(3)$

$\rm = 168 - 6$

$\boxed{\rm = 162}$

How do i find the answer to this

dybincka [34]

If you “unfold” the wrapping paper around this triangular prism, you have
2 triangles
Base 40, to find the height(dotted perpendicular line segment)
a^2 + b^2 = c^2. ... 20^2+ b^2 = 29^2 … 400+ b^2 = 841
- 400. -400
b^2 = 441 … b=21 this is height
1/2(40)(21) = 420 + 420

3 rectangles
Two are 70x29 = 2030 +2030
One is 70x40 = 2800

Add all 5 numbers:
420
420
2030
2030
+ 2800
7700
