Answer:[tex]r = 2.82[/tex]Step-by-step explanation:

Given:

[tex]A = 25[/tex]

Let's simplify.

=> [tex]25 = \frac{22}{7} r^{2}[/tex]=> [tex]\frac{25}{\frac{22}{7} } = \frac{\frac{22}{7}r^{2} }{\frac{22}{7\\} }[/tex]=> [tex]\frac{7(25)}{22} = r^{2}[/tex]=> [tex]\sqrt{\frac{25(7)}{22}}= \sqrt{r^{2}}[/tex]=> [tex]\sqrt{\frac{25(7)}{22}}= r[/tex]=> [tex]r = 2.82[/tex] (Estimated)

Therefore, r ≈ 2.82.

Hoped this helped.

Answer 2

Answer:

r= 5/√  π

or

r=2.820948 or simplified =2.82

In ΔABC, ∠B is a right angle, AB = 30, and sec A = 5/3. Find the value of csc C in fraction and in decimal form.
I will mark brainliest if you are correct!

Answers

The value of csc C in fraction and in decimal form is as follows:

csc C  = 5 / 3

csc C = 1.66666666667

Using trigonometric ratio,

secant A = 1 / cos A = hypotenuse / adjacent

Therefore,

sec A = 5/3

sec A = 1 / cos A

cos A = adjacent / hypotenuse

cos A = 3 / 5

A = cos⁻¹ 0.6

A = 53.1301023542

Therefore,

∠A = 53°

∠B = 90°

∠C = 180 - 143 =  37°

cosec C = 1 / sin C = hypotenuse / opposite

cosec C = 5 / 3

Answers

Answer:

  9:50

Step-by-step explanation:

It appears the sequence has 0:51 as the first difference, and those differences increase by 0:01 in each interval. That means ? must be chosen so that ...

  ? - 8:58 = 0:52   ⇒   ? = 8:58 +0:52 = 9:50

  10:43 -? = 0:53   ⇒   ? = 10:43 -0:53 = 9:50

The missing time is 9:50.

If one plane is flying 40 mph and another plane is flying 100 mph, and they
are 200 miles apart and flying directly toward each other, in how long will the planes

Answers

Answer:

i think 60 miles

Step-by-step explanation:

I just added the 100+40 then

200-140

Answer:

  1 3/7 hours

Step-by-step explanation:

The planes are closing the 200 mile separation distance at a rate of (40 +100) = 140 miles per hour. The time it takes for that distance to be closed is ...

  time = distance/speed

  time = (200 mi)/(140 mi/h) = 200/140 h = 10/7 h = 1 3/7 h

The planes will meet after 1 3/7 hours, about 1 hour 25 minutes 43 seconds.

Answer:

Y-intercept: (0, -10)

X-intercepts: (5,0), (1,0)

Axis of symmetry: (3,0)

Step-by-step explanation:

You can tell what the y-intercept is by looking at the function. At the end there is a “-10”, which indicates that it’s the y-intercept.

There are many ways to find x-intercepts. You can factor the function, use the quadratic formula, or complete the square.

By factoring it, you get

-2(x-5)(x-1)=0

If one part of it equals zero, than the whole function equals zero.

So it can be split up like this

(x-5)=0

(x-1)=0

So...

x=5 and x=1 are the the zeros or (5,0) and (1,0)

Finally, you convert the function from standard form to vertex form. By doing -b/2a, you can find the x-coordinate of the vertex, which is the axis of symmetry. The answer is 3 or (3,0) because -12/2(-2)= 3.

Pls help me with this

Answers

Step-by-step explanation:

a)

clearly, A and B are mirrored images of each other around the x-axis.

and the equation of the x-axis is simply

y = 0

b)

this is trickier.

first of all, the mirror line is now vertical and not horizontal.

and where is it ? of course, in the middle between A and B.

how many units are there between A and B ?

I am counting 5. so, the middle between them is 2.5 units.

so, let's go e.g. from A 2.5 units to the right (in the direction of B).

where do we end up ? at x = 0.5

and that is also the equation of the vertical line there.

again

x = 0.5

A rectangular garden has a walkway around it. The area of the garden is 4(2.5x + 1.5). The combined
area of the garden and the walkway is 5.5(4x + 4). Find the area of the walkway around the garden as
the sum of two terms.

Answers

Answer:

Area of Walkway = 12x+16

Step-by-step explanation:

Area of Garden = 4(2.5x + 1.5)  [Garden Area]:  (10x + 6)

Area of Garden and Walkway = 5.5(4x+4) [Total Area]:  (22x + 22)

Area of Walkway = [Total Area] - [Garden Area]

Area of Walkway = [5.5(4x+4)] - [4(2.5x + 1.5)]

Area of Walkway = [22x+22)]   - [10x + 6)]

Area of Walkway = 12x+16

Step-by-step explanation:

a) The area A of a rectangle is given by the formula, A=lw

12 * 6 = 72cm²

b) To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2.

(6 * 3) : 2 = 9 cm²

c) To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2.

(6 * 3) : 2 = 9 cm²

d) To find the area of the parallelogram, multiply the base of the perpendicular by its height.

(12 - 3) * 6 = 54 cm²

Find the solution of the system of equations.

2x-3y=-14
5x+9y=-2

Answers

Answer:

Well to solve this I’m gonna use substitution

So

2x-3y=-14

5x+9y=14

I‘m gonna isolate ”x” on the first equation

So it’ll be

2x-3y=-14

2x=-14+3y

x=-7+1.5y

X is -7+1.5y

Now you can subsitute into other equations to find what Y is worth

So lets use the second equation

5(-1+1.5y) + 9y = 14

Now solve for y which is -2

If you subsitute Y back in an equation you’d get -4 for x

So y = -2

and X= -4

Its customers are mainly fashion boutiques. Bebe Co has two directors, one of who is non-executive. The other is involved in the day-to-day administration of the company. There are ten other employees. Six of these work in the factory, one works in the warehouse, one is a sales representative and two are accounts staff. The accounts staff consist of Miss Ines, who is responsible for processing sales and receivables, and Mrs. Evie, who is the purchases and wages clerk. Mrs. Evie works part-time, five mornings a week. The company's sales representative visits shops throughout the region. He takes orders from customers which he records on a pre-numbered two-part order form. He passes the completed forms to the accounts department. Miss Ines files one copy of the order form in numerical sequence and passes the other to the warehouse.The completed order is dispatched from the warehouse by the carrier, accompanied by one copy of a dispatch note. The other copy is sent to Miss Ines, who prepares an invoice based on the information it contains and on the company's price list. She sends one copy of the invoice to the customer, and a second copy of the invoice is retainedEach Friday, Miss Ines inputs the week's invoices to the computerized sales ledger. She then files the invoices alphabetically by customer name. Dispatch notes are not retained because filing space is limited. Miss Ines opens the post daily and lists remittances received from credit customers. Every Friday, she inputs the information listed to the sales ledger. Cheques received are banked daily by the executive director.Miss Ines reviews the sales ledger balances every month and writes to customers who have not paid within 90 days of receiving goods. The sales ledger is printed out annually for year-end purposes. Otherwise, no hard copy is printed, and Miss Ines reviews the sales ledger on the computer screen. The company's computer package includes the facility to produce a sales day book and sales ledger control account.
