Answer:

Step-by-step explanation:

$x^{2}-\frac{16}{25}=0\\\\x^{2}=\frac{16}{25}\\\\\sqrt{x^{2}}=\sqrt{\frac{16}{25}}\\\\\sqrt{x*x}=\sqrt{\frac{4*4}{5*5}}\\x=+\frac{4}{5} or -\frac{4}{5}\\$

Which graph shows that Cindy reads about 3/4 of the time while riding in the car?

wolverine [178]

The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.

Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.

Unite rate (k) = x/y.

In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.

Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.

Which answer choice correctly solves for a and b?

Zepler [3.9K]

Answer:

Step-by-step explanation:

Using the sine ratio and the exact value sin45° = $\frac{1}{\sqrt{2} }$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{6}{a}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

a = 6 $\sqrt{2}$

Using the tangent ratio and the exact value tan45° = 1 , then

tan45° = $\frac{opposite}{adjacent}$ = $\frac{6}{b}$ = 1 , so

b = 6

Simplify 8 - {x - (5 + x)}. 3 13 -2x + 3 -2x + 13

love history [14]

<span>Simplify 8 - {x - (5 + x)}:

Order of operations rules require that you perform work inside parentheses first. Thus, do this first: </span>x - (5 + x) => x - 5 - x => -5.

Now we have the following: 8 - {-5} => 8+5 = 13 (answer)

Please note: To avoid confusion, please separate answer choices, such as <span>3 13 -2x + 3 -2x + 13, by using commas or by putting each choice on its own new line:

</span><span>3
13
-2x + 13
I was and still am unsure of what you meant here.</span>

808, 408, 208,108, 68 find out wrong number.

EastWind [94]

68 is the wrong number in the sequence 808, 408, 208,108, 68

<h3>What is Number system?</h3>

A number system is defined as a system of writing to express numbers.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given sequence is 808, 408, 208,108, 68

Eight hundred eight, Four hundred and eight, two hundred and eight, one hundred eight and sixty eight.

808, 408, 208,108, 68

Let us find the difference between the consecutive numbers

400, 200, 100, 40

As we observe the first three terms having the common ratio where as 40 and 100 has different ratio.

Hence, 68 is the wrong number in the sequence 808, 408, 208,108, 68
