To find the area of a circle, use the following formula; A = πr^2

The radius of a circle is half the diameter.

So;


4.) 18/2 = 9

Radius = 9


(3.14)9^2

9(9) = 81(3.14)

254.34 is the area of figure #4.


5.) 12/2 = 6

A = (3.14)(6)^2

A = (3.14)(36)

Please help 20 points

Answers

Answer:

(4,2)

Step-by-step explanation:

I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.

So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

A famous monument is 300 ft tall. When it casts​ 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall is the​ tree?

Answers

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets

D. x ≥ 2

Answers

c

Step-by-step explanation:

if you look at the graph, if there is a closed circle, that means x can be equal to whatever number the circle is on. if the circle is open, that means you don't include that number, which is in this case two. a closed circle means that x can be equal to 2. since the arrow is going from 2 to the left, x can be anything from two to any real numbers to the left. therefore, since to the left goes to numbers smaller than 2, x can either be equal to or less than two.

The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.

Here inequality is given as;

3/4 x - 2/3 ≤ 5/6

What is inequality?

A statement of an order relationship; less than, greater than, greater than or equal to, less than or equal to, between two algebraic expression is known as inequality.

Now,

3/4 x - 2/3 ≤ 5/6

3/4 x - 2/3 + 2/3 ≤ 5/6 + 2/3

3/4 x ≤ 7/3

Now multiply both side by 4/3;

[tex]\frac{3}{4} x *\frac{4}{3} \leq \frac{7}{3} *\frac{4}{3} \\x\leq \frac{28}{9} \\x\leq 3.11\\[/tex]

Hence, The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.

At the country fair, Maya observes that the wheel of chance has 25 numbered slots. If each play costs a quarter, how much will Maya likely have to spend before she gets her winning number?

Answers

Answer:

6 1/4

Step-by-step explanation:

Given

Total number of wheel chance = 25

Each play = 1 quarter

1 play = 1/4

To calculate the amount Maya has to spend to get her winning number, we will say;

25 plays = x

Divide both expressions

1/25 = 1/4÷x

1/25 = 1/4x

Cross multiply

4x = 25

x = 25/4

x = 6 1/4

This mean that Maya will have to spend 6 1/4 before she gets her winning number

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?

Answers

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

[tex] =\tt 2500 - 2245[/tex]

[tex] =\tt 255[/tex]

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]

[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]

[tex] =\tt 255 = \frac{2500x}{100} [/tex]

[tex] = \tt255 \times 100 = 2500x[/tex]

[tex] = \tt25500 = 2500x[/tex]

[tex] =\tt \frac{25000}{2500} = x[/tex]

[tex]\color{plum} =\tt \bold{10.2\%}[/tex]

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%
