Answer:

3.3

Step-by-step explanation:

In equations you must remember the important rule of keeping both sides balanced. If you do one operation to one side you must do it to the other, for example if you added 1.1 to the right side you must do it to the left side in order to keep the equation balanced so,

→ 2.2 = z - 1.1

⇒ Add 1.1 to both sides to isolate z

→ 3.3 = z

⇄ We can substitute 3.3 back into the equation to see if we have the right solution, if we get 2.2 on both sides then our solution is correct

→ 2.2 = z - 1.1

⇒ Substitute 3.3 into the equation

→ 2.2 = 3.3 - 1.1

⇒ Simplify

→ 2.2 = 2.2

Our solution of z = 3.3 is correct

JKLM is a rhombus. KM is 20 and JL is 48. Find the perimeter of the<br><br> rhombus.

anygoal [31]

Answer:

104 units

Step-by-step explanation:

Given

Shape: Rhombus

$JL = 48$

$KM = 20$

Required

Determine the perimeter

The given parameter are the diagonals of the rhombus.

The perimeter (from diagonals) is calculated as thus:

$P = 2\sqrt{(JL)^2 + (KM)^2}$

Substitute values for JL and KM

$P = 2\sqrt{48^2 + 20^2}$

$P = 2\sqrt{2304 +400}$

$P = 2\sqrt{2704}$

$P = 2 * 52$

$P = 104$

<em>Hence, the perimeter is 104 units</em>

Please help with Geometry homework!!! Will give brainliest and 50 points to whoever answers first!!!

melomori [17]

Answer:

x = 42.5

Step-by-step explanation:

It is said:

If two angles are not corresponding, then they make up 180°. They are more known as supplementary angles.

So the equation is:

a + b = 180°

Substitute

x + 8 + 3 x + 2 = 180°

x + 3x + 8 + 2 = 180°

4x + 10° = 180°

4x = 180° - 10°

4x = 170°

x = 170° ÷ 4

x = 42.5

Given log Subscript 3 Baseline 2 almost-equals 0. 631 and log Subscript 3 Baseline 7 almost-equals 1. 771, what is log Subscript

kari74 [83]

You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

$log_3(14) \approx 2.402$

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

$a^b = c$

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

$b = log_a(c)$

Some properties of logarithm are:

$log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})$

<h3>Using the above properties</h3>

$log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771 = log_3(14)\\\\log_3(14) = 2.402$

Thus,

The approximate value for given term is given by

$log_3(14) \approx 2.402$
