new unit i’m confused

Answer:

201.06

Step-by-step explanation:

A=πr2=π·82≈201.06193

Answer:

201.14 ≈ 201 unit²

Step-by-step explanation:

Area of circle = πr², where π is either 3.14 or 22/7 or 355/113. Mostly it is 22/7.

=> area of circle = (22/7) (8)² unit²

=> area of circle = (22 x 64)/7 unit²

=> area of circle = 201.14 unit²

If we take π = 3.14

=> area of circle = (3.14)(8)² = 200.96 unit²

Answer:

25

Step-by-step explanation:

If it's 5 for every 4 and the bag has 20, 4*5 = 20 and you'd have to do that to the 5 as well to get 5*5=25.

Answer:

The slope is 4

The y-intercept is 3 OR (0, 3)

Step-by-step explanation:

Points on the graph: ( -1, -1) and (0,3)

Slope:

m=(y2-y1)/(x2-x1)

m=(3+1)/(0+1)

m=4/1

m = 4

Point slope-intercept:

y - y1 = m(x - x1)

y + 1 = 4(x + 1)

y + 1 = 4x + 4

y = 4x + 3

Answer:

Total fringe needed = 132 inches

Step-by-step explanation:

P.S - The exact question is -

Given - Alejandra plans to sew fringe on a scarf. The scarf is shaped like a rectangle. The length of the scarf is 44 inches. The width is one half the length.

To find - How much fringe does Alejandra need?

Proof -

Total fringe needed = Perimeter of the rectangle.

Now,

We know that,

Perimeter of the Rectangle = 2(Length + Width)

Now,

Given that,

Length = 44 inches

Width = one half the length

          = [tex]\frac{1}{2}[/tex] × 44 = 22 inches

⇒Width = 22 inches

∴ we get

Perimeter of the Rectangle = 2(44 + 22)

                                             = 2(66) = 132 inches

⇒Perimeter of Rectangle = 132 inches

∴ we get

Total fringe needed = Perimeter of the rectangle = 132 inches

⇒Total fringe needed = 132 inches

Answer:

45x^2-328x+124

Step-by-step explanation:

Answer: if you take 2,000- (-3,500) you get 5,500 ft, making this the distance. Also, think about it this way 2,000 is 2,000 ft from 0, and then there is another 3,500 past zero, putting these together makes the amount of space they are away from each other in total.

Note that when subtracting a negative it becomes positive, using the keep change change rule 2,000 - (-3,500) becomes 2,000 + 3,500

Answer:

A9 = 393216

Step-by-step explanation:

the first thing that will help you solve this question is finding the common ratio between each terms

the first thing that I like to do that usually helps is to take the second term (-24) and divide it by the first term (6) --> this will usually help you spot the common ratio fairly quickly

in your case, the common ratio is -4

- you can also check this by following my note above and then multiplying the second term by the common ratio to see if it matches the third term, which it does!

so now you can go about this two different ways

1. solve directly for the 9th term

2. use the nth term formula for geometric sequences

METHOD 1:

if you continue to multiply by -4 to solve for each term you would end up with:

6, -24, 96, -384, 1536, -6144, 24576, -98304, 393216

and you will recieve 393216 as your answer

METHOD 2:

the nth term formula is An = A1*r^(n-1)

where An = the nth term of the sequence

A1 = first term of the sequence (6)

and r = common ratio

using this formula, you would get:

A9 = 6(-4)^8

A9 = 393216

I hope this helped :)

Answer:

$872.70

Step-by-step explanation:

Add all numbers from Mon-Fri.

So 985.

Multiply it by 0.78

So $768.30

Add 0.78 and 0.38

So 1.16

Then multiply 90 by 1.16

So $104.40

Then add the two numbers.

768.30+104.40

So $872.70

Hope this helps

Answer:

199.8 km to the 1 decimal point

Step-by-step explanation:

8:36 to 9:00 is 24 min

9:00 to 10:00 is 60 min

10:00 to 10:57 is 57 min

That's a total of 24 + 60 + 57 = 141 min = 141/60 hr.

d = rt = 141/60(85) = 199.8 km to the 1 decimal point

Step-by-step explanation:

Answer:

∠A = 77°

Step-by-step explanation:

Given:

Inscribe quadrilateral

Opposite angles

∠A = (2x + 9)°

∠B = (3x + 1)°

Find:

Value of ∠A

Computation:

We know that in Inscribe quadrilateral sum of Opposite angles are 180

So,

(2x + 9)° + (3x + 1)° = 180°

5x + 10 = 180

x = 34°

So,

∠A = (2x + 9)°

∠A = 2(34) + 9°

∠A = 77°

Answer:

x = 33°

Step-by-step explanation:

From the figure attached,

FB and FC are two secants intersecting each other at point F outside the circle.

Measure of angles between the secants measures half of the difference between the intercepted arcs.

x° = [tex]\frac{1}{2}(\text{arc BC}-\text{arc DE})[/tex]

x° = [tex]\frac{1}{2}(108-42)[/tex]

x = 33°

Answer:

Her potential energy is approximately 4481 J.

Step-by-step explanation:

Because the formula for potential energy is PEg = 9.81 * mass * height, just plug in the knowns. After you plug those in, you will get the potential energy as 9.81 * 450, which is approximately 4481 J.
