Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

To estimate the sum or difference of 8/9 + 4/7 it should be <span>1 1/2

</span>It is also a way to find<span> an approximate answer to a solution. To </span>estimate<span> products and quotients of mixed numbers, round the </span>fractions<span> to the nearest whole number. If the </span>fraction<span> is less than 12 round down and if it is more than 12 round up. First, since 411 is less than 12,8411 rounds down to 8.</span><span>

Answer

the estimated sum is 11.59

And the estimated difference is

0.32

Step-by-step explanation:

The question bothers to know how well you understand your fraction

In a step by step approach we will estimate both the sum and the difference

Step one

Let us know what the sum is

8/9+4/7

The Lcm can be gotten by multiplying the denominators

9x7=63

56+36/63= 92/63

=11.59

Hence the estimated sum is 11.59

Step two

Let us estimate the difference also we have

8/9-4/7

Like before our Lcm =63

56-36/63=20/63

=0.32

Our estimated difference is 0.32

juin [17]

Answer:

From the level of high tide to low tide, it's 18 feet.

Step-by-step explanation:

To find the change in water level, we multiply the rate (3 ft / hr) by the time (6 hrs), obtaining 18 ft.

The water level changes by 18 ft.

Triangle Congruence Theorems
elixir [45]

Triangle Congruence Theorems

Use the triangle congruence theorems below to prove that two triangles are congruent if:
Three sides of one triangle are congruent to three sides of another triangle (SSS: side side side)
Two sides and the angle in between are congruent to the corresponding parts of another triangle (SAS: side angle side)
Two angles and the side in between are congruent to the corresponding parts of another triangle (ASA: angle side angle)
Two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle (AAS: angle angle side)
The hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle (HL: hypotenuse leg)

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing side length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 72

Leg <em>b</em> = 65

Hypotenuse <em>c</em> = <em>x</em>

<em />

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    72² + 65² = x²
  2. Exponents:                           5184 + 4225 = x²
  3. Add:                                      9409 = x²
  4. Isolate <em>x</em>:                               97 = x
  5. Rewrite:                                x = 97
