At this weekend’s football game, 20 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 300 people attending the game, about how many of them will probably NOT be wearing hats? Show all work and justify your answer.

Answer:

Equation: 2.5x + 16 = 3.75x + 11

Hours: 4

Step-by-step explanation:

Hi,

The equation would be...

2.5x + 16 = 3.75x + 11

(To find the solution, you have to set the equations equal to each other)

2.5x is the cost per hour at Happy Paws and the 16 is the charge. For Woof Watchers, the 3.75x is the cost per hour and the 11 is the charge.

Now solve...

2.5x + 16 = 3.75x + 11

Subtract 16 on both sides...

2.5x = 3.75x - 5

Subtract 3.75x on both sides...

-1.25x = -5

Divide by -1.25 on both sides...

x = 4

So at 4 hours, both services will have an equal total of cost.

Hope this helps :)

Answer:

the answer is 30,20,35 in that order

Step-by-step explanation:

Step-by-step explanation:

y=mx +b

b= 5

12.5= 10m+5

10m = 7.5

m= 0.75

y=0.75x +5

..........

at x= 20 , y= 20

at y= 27.5 , x= 30

at x= 40 , y= 35

Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

[tex]\frac{DB}{DC}[/tex] = [tex]\frac{AD}{BD}[/tex] , substitute values

[tex]\frac{DB}{17.8-5}[/tex] = [tex]\frac{5}{BD}[/tex]

[tex]\frac{DB}{12.8}[/tex] = [tex]\frac{5}{BD}[/tex] ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = [tex]\sqrt{64}[/tex] = 8

The length of segment DB is 8 units.

From the given right triangle we can deduce the following;

From the corresponding triangle rules, we can calculate the length of DB by considering the following ratios;

[tex]\frac{DB}{DC} = \frac{AD}{DB} \\\\DB^2 = AD\times DC\\\\DB^2 = 5 \times (17.8-5)\\\\DB^2 = 5 \times 12.8\\\\DB^2 = 64\\\\DB = \sqrt{64} \\\\DB = 8 \ units[/tex]

Thus, the length of segment DB is 8 units.

Step-by-step explanation:

linear equation slope intercept form:

m is 1 in this question

therefore

substitute the value of m and b

Answer:

y = x + 3

Step-by-step explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3).  The y-intercept is also represented by (0, 3).  The graph also goes through (-3, 0).  The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3.  Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution.  In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

Answer:

∠s + ∠y are complementary

∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90

4y - 100 + y = 90

5y = 90 + 100

5y = 190

y = 38

Ans: y = 38°

Answer: the least number of deliveries that Ben must make is 14.

Step-by-step explanation:  Given that Ben earns $9 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday.

We are to find the least number of deliveries he must make to reach his goal.

Let x be the least number of deliveries that Ben must make to reach his goal.

Then, according to the given information, we have

Thus, the least number of deliveries that Ben must make is 14.
