Answer:

y > -x -3

Step-by-step explanation:

The graph is shaded above the dashed line, indicating y-values in the solution are greater than those on the line, so your inequality will start with ...

y >

The y-intercept of the line is (0, -3), so the "b" value in ...

y > mx +b

will be -3.

The line has a rise of -3 for a run of 3 (between the marked points), so the slope is ...

m = rise/run = -3/3 = -1

Then the inequality you want is ...

y > -x -3

The ratio of men to women at a basketball game was 3 to 5 there were 128 adults at the game how many men were at the game

Andreyy89

Ratios are used to show the proportions of two quantities.

There were 48 men at the game, if the total number of adults is 128.

Let:

$M \to Men$

$W \to Women$

So, we have:

$M : W = 3 : 5$

The total ratio is:

$Total = M + W$

$Total = 3 + 5$

$Total = 8$

The number of men at the game is calculated using:

$Men = \frac{M}{Total} \times Adults$

So, we have:

$Men = \frac{3}{8} \times 128$

$Men = 3 \times 16$

$Men = 48$

Hence, there are 48 men at the game

Answer:

a) 5 cm

b) 8 cm

c) 9 m

Step-by-step explanation:

It can be worthwhile to work the last attachment (a) first, since these are all variations of the same triangle.

The Pythagorean theorem tells you the sum of the squares of the legs is the square of the hypotenuse.

Problem 6a:

3² +4² = x² . . . . fill in the given numbers; all measures in cm

9 + 16 = x² . . . . simplify exponents

25 = x² . . . . . . . simplify sum

x = √25 = 5 . . . take the square root.

x = 5 cm . . . . . . apply units

Note that this triangle is a 3-4-5 right triangle. That is a set of side lengths (ratios) that is useful to remember. In this problem set, you see it again immediately.

Problem 6b:

Shortest-to-longest, the side ratios of the given triangle are ...

6 : x : 10

For some x', this is ...

3 : x' : 5 . . . . . . . . . . . . . matches a 3-4-5 triangle with x' = 4

The scale factor is 6/3 = 10/5 = 2, so we have ...

x = 2·x' = 2·4 = 8

x = 8 cm . . . . . with units

Problem 6c:

The side ratios are ...

x : 12 : 15 which reduces to x' : 4 : 5

This matches a 3-4-5 triangle with x' = 3, and a scale factor of 12/4 = 15/5 = 3.

Then ...

x = 3·x' = 3·3 = 9

x = 9 m . . . . . with units
