Answer:

530.66 m²

Step-by-step explanation:

The equation to find a circle's area is [tex]\pi[/tex][tex]r^{2}[/tex]. We just need to plug in the radius.

[tex]\pi[/tex][tex]13^{2}[/tex]

= 3.14*169

= 530.66

Hope this helps you and have a great day! o(*^v^*)o

Answer:

35 hours

Step-by-step explanation:

Clara worked for 35 hours because when you do $315/9 it equals 35. So 35 represents the hours she worked last week, and then the equation would just be, 315/9.

Answer:

y=2x+2  and increasing

Step-by-step explanation:

we see there is a pint (0,2)  so the y intercept is 2, we know the slope is 2 because the slope formula can be used on ay two points, for example (0,2) and (1,4)    4-2 is 2 and 1-0 is 1.    2/1 =2 so the slope is 2

The height of up in the tree was the bald eagle is, 352.5 feet

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

You measure the angle of elevation to the eagle to be 67 degrees.

And, The angle of elevation to the eagle to be 67 degrees.

Now, Let the height of up in the tree was the bald eagle is, x

Hence, We can formulate;

⇒ tan 67° = x / 150

⇒ 2.35 = x / 150

⇒ x = 2.35 × 150

⇒ x = 352.5 feet

Thus, The height of up in the tree was the bald eagle is, 352.5 feet

Answer:

3 * 20s

Step-by-step explanation:

In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...

3 * (13.50s + 6.50s)

We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s

3 * 20s

Answer:

y = - 6x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 9) and (x₂, y₂ ) = (0, - 3)

m = [tex]\frac{-3-9}{0+2}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6

The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = - 6x - 3 ← equation of line

Answer:

74 days

Step-by-step explanation:

The computation is shown below;

The proportion that remains left after d days is

p = (1/2)^(d ÷ 100)

In the case when the proportion is 60%

So,  

0.60 = 0.50^(d ÷ 100)

Now

log(.60) = (d ÷ 100)log(.50)

100·log(.60) ÷ log(.50) = d = 74 days

Answer:

10/7 feet

Step-by-step explanation:

Let e = Ethan

k = Kayla

The following equations can de derived from the equation :

1/2 e = 2/3k

multiply both sides of the equation by 2

e = 4/3k --- 1

e + k = 10 --- 2

Substitute for e in equation 2

4/3k + k = 10

7/3k = 10

multiply both sides of the equation by 3/7

k = 30/7

Substitute for k in equation 1

e = (4/3) x 30/7 = 40/7

difference in length = 40/7 - 30/7 = 10/7

Answer:

Salma, joe, and alan sent 14, 69, and 23 text messages respectively

Step-by-step explanation:

Given that Salma, joe, and alan sent a total of 106 text messages during the weekend, it means that

s + j + a = 106 where s, j, and a are the number of messages sent by Salma, joe, and alan respectively

Given salma sent 9 fewer messages than alan

s = a - 9

Joe sent 3 times as many messages as alan

j = 3a

hence

a - 9 + 3a + a = 106

5a - 9 = 106

5a = 106 + 9

5a = 115

Divide both sides by 5

a = 115/5

= 23

s = 23 - 9

= 14

j = 3* 23

= 69
