Answer:

Option C - 10

Step-by-step explanation:

Given : Function $f(x)=5x$

To find : Evaluate the function for the value x=2

Solution :

We have given the function $f(x)=5x$

We have to find the value of f(x) at x=2

Substitute x=2 in the given function f(x)

$f(x)=5x$

$f(2)=5(2)$

$f(2)=10$

Therefore, Option C is correct.

Answer: Part A = (100% - 80%)P = 35, Part B = 140

Step-by-step explanation:

Percentage: Like + Don't like = 100%

80% + Don't like = 100%

-80% -80%

Don't like = 20%

People: 20% of Patrons = Don't Like

0.20 x Patrons = 35

÷ 0.20 ÷ 0.20

Patrons = 175

Now, let's write the equation we used to get that answer:

Let P represent the total number of patrons, then the equation is:

(100% - 80%)P = 35

= (1.00 - 0.80)P = 35

= 0.20P = 35

= P = 175

Part B:

80% of Patrons = Like

0.80 x 175 = Like

140 = Like

There are approximately 4.3 weeks in each month. How much will you take home each month after taxes?

Answer:

So roughly c x c = b/100

5 x 5 x 100 = $2500

Step-by-step explanation:

Lets say c = 5 and b = 1

= 5c =100c/5c x b

= 20c x b

We can also show

= 20c x b =5c

c = 20c/5c x b = 5c

1/20 x 5c = 5c

b=1

One example is 20% = 0.20 x 500 = 100c

= 7.12c = 7c

1= 100%

100 x 71.042 = 710.42 weekly pay. emergency tax 142 = 568

100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107

710-107 = 603 a week

4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29

Nick has designed a diamond shaped kite as shown below. The measures of some sides of the kite are marked in the figure. Find th

Zepler [3.9K]

Answer:

Step-by-step explanation:

In a kite, the diagonals are perpendicular. Hence $\Delta DOC$ is a right angled triangle.

$DC=7\text{ }in,\text{ }OC=5\text{ }in$

From Pythagoras theorem, since $\Delta DOC$ is a right angled triangle, $DO^{2}+OC^{2}=DC^{2}$ .

Area of $\Delta DOC$ = $\frac{1}{2}\times base\times height$

$=\frac{1}{2}\times DO\times OC=\frac{1}{2}\times OP\times DC\\(2\sqrt{6})\times(5)=(7)\times(OP)\\OP=3.499\text{ }in$

From diagram $OP=x$

∴ $x=3.499\text{ }in$
