Answer: F.) 7 triangles

Step-by-step explanation:

Congruent means completely equal in side lengths and angles. Think of this weird figure like 4 triangles that are see through and are covering a diamond underneath

Of those 4 "see through triangles", there are 3 equal to ΔABC

Now on the diamond underneath, there is another 4. Its hard to actually explain what I mean, but take two triangles from that dimaond. Theyre gonna be congruent to ΔABC.

That's 4 + 3 = 7 total triangles

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Earth is approximately 1.3×104 kilometers. About ho

-Dominant- [34]

Hi there!

To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

$\frac{1.3*10^4}{4.9*10^3}$

We can change this to

$\frac{1.3}{4.9}*\frac{10^4}{10^3}$

Let's solve for each individual fraction

$\frac{1.3}{4.9}$ ≈ 0.27

$\frac{10^4}{10^3}$ = 10

Now, multiply.

0.27 * 10 = 2.7

That's your answer.

Have an awesome day/night! :)

Z−4/9−1/3=5/9 Enter your answer as a fraction in simplest form in the box. z =

aleksklad [387]

Answer:

z = 4/3 or 1 1/3

Step-by-step explanation:

z−4/9−1/3=5/9

Change 1/3 to have a denominator of 9

1/3 *3/3 = 3/9

z−4/9−3/9=5/9

Combine like terms

z -7/9 = 5/9

Add 7/9 to each side

z-7/9+7/9 = 5/9+7/9

z = 12/9

z=4/3

or as a mixed number

z = 1 1/3
