Answer:

The correct answer ir B)5

Step-by-step explanation:

An easy explanation of what a ratio is, is the following:

It is the relationship between two numbers, indicating how many times the first number contains the second.

So, we should divide the first by the second, in all the ratios to know the relation:

3/6=0,5

7/14=0,5

If they are Equivalent that means they all give as a result 0,5.

x/10=0,5

x=0,5*10

x=5 (answer b)

What is the length of BC? If your answer is not an integer, leave it in simplest radical form?

nexus9112 [7]

ANSWER

$|BC|=12\sqrt{2}\: ft$

EXPLANATION

The given right triangle is an isosceles triangle because

$m \: < \: B = 45 \degree = m \: < \: C$
This implies that,

$|AB|=12ft=|AC|$

From the Pythagoras Theorem,

$|BC|^2=|AB|^2+|AC|^2$

$|BC|^2= {12}^{2} + {12}^{2}$

$|BC|^2=2 \times {12}^{2}$

$|BC| = \sqrt{ {12}^{2} \times 2 }$

$|BC|=12\sqrt{2}\: ft$

Part A: Consider the equation x + 7 = 16. Which number from the set {5, 7, 9, 11} makes the equation true?

wel

Part A: Substitute/plug in each number into the equation to see which number will make the equation true.

x + 7 = 16 Plug in 5 into "x"

5 + 7 = 16

12 = 16 5 doesn't make the equation true because it equals 12 not 16

x + 7 = 16 Plug in 7 into "x"

7 + 7 = 16

14 = 16 7 doesn't make the equation true because it equals 14 not 16

x + 7 = 16 Plug in 9 into "x"

9 + 7 = 16

16 = 16 9 makes the equation true because it equals 16

Part B: Plug in 9 into "x" in the inequality to see if it still makes it true.

x + 7 < 16 [x plus 7 is less than 16]

9 + 7 < 16

16 < 16 [16 is less than 16] The same number would not make the inequality true because 16 can't be less than itself.

To figure out which numbers satisfy the inequality, plug it into the inequality:

x + 7 < 16 Plug in 5 into "x"

5 + 7 < 16

12 < 16 5 does satisfy the inequality because 12 is less than 16

x + 7 < 16 Plug in 7 into "x"

14 < 16 7 does satisfy the inequality because 14 is less than 16

x + 7 < 16 Plug in 11 into "x"

11 + 7 < 16

18 < 16 11 doesn't satisfy the inequality because 18 isn't less than 16
