Answer:

[tex]\boxed {\tt 69.08 \ centimeters}[/tex]

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

[tex]c= \pi d[/tex]

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.

[tex]d= 22 \ cm[/tex]

[tex]c= \pi* 22 \ cm[/tex]

We also know we are using 3.14 for pi. Substitute it in for pi.

[tex]c= 3.14 * 22 \ cm[/tex]

Multiply.

[tex]c=69.08 \ cm[/tex]

The circumference of the circle is 69.08 centimeters.

Answer:

Circumference = 69.08 cm

Step-by-step explanation:

Diameter = 22

Radius = 22/2

= 11

Circumference = 2πr

= 2 × 3.14 × 11

= 69.08 cm

Answer:

1.8 feet

Step-by-step explanation:

This is the answer because:

Perimeter = L + W + L + W

1) Since we know the width of the rectangle is 1.9 feet, let's add 1.9 + 1.9 which is 3.8

2) Now, we know the total perimeter is 7.4, therefore, subtract 7.4 - 3.8 which is 3.6

3) Next, divide 3.6/2 which is 1.8

4) Finally, you can check your work by adding 1.8 + 1.8 + 1.9 + 1.9 which equals 7.4

Hope this helps!

Step-by-step explanation:

Answer:

The cost price of the article was Nu 1,000

The original selling price was Nu 1,120

The second selling price was Nu 1,200

Step-by-step explanation:

System of Equations

Let's call:

x = Original selling price of the article

y = Cost of the article

The first condition implies that the difference between the selling price and the cost price (the profit) is 12%. Recall the profit % is always calculated with respect to the cost, that is, the profit at the first condition is:

0.12y = Original profit

Setting up the equation, we have:

[tex]x-y=0.12y[/tex]

The second condition states the selling price is 80 Nu more than before, that is:

x+80= Second selling price of the article

y = Cost of the article (it doesn't change)

The profit of this condition is 20%, thus:

0.2y = Second profit

This produces a second equation:

[tex]x+80-y=0.2y[/tex]

Let's put both equations together to form a system of equations:

[tex]x-y=0.12y[/tex]

[tex]x+80-y=0.2y[/tex]

Operating on both equations:

[tex]x=1.12y[/tex]

[tex]x=1.2y-80[/tex]

Equating both equations, we have an equation with only y's:

[tex]1.12y=1.2y-80[/tex]

Subtracting 1.2y on each side:

[tex]1.12y-1.2y=-80[/tex]

Operating:

[tex]-0.08y=-80[/tex]

Solving:

[tex]\displaystyle y=\frac{-80}{-0.08}=1,000[/tex]

a)

The cost price of the article was Nu 1,000

b) The selling price of the article will be calculated in both cases:

Original selling price: x=1.12y= 1.12*1000=1,120

The original selling price was Nu 1,120

The second selling price was x+80=1,200

The second selling price was Nu 1,200

Answer:

  1059 ft

Step-by-step explanation:

For problems like these, we assume the acceleration due to gravity is -32 ft/s², so the velocity will decrease to zero in time t, where ...

  0 = 256 -32t

  32t = 256

  t = (256 ft/s)/(32 ft/s² ) = 8 s

Since velocity is linearly decreasing from 256 ft/s to 0, its average value of 128 ft/s will serve to tell us the height attained.

Height attained is ...

  35 ft + (128 ft/s)(8 s) = 35 ft + 1024 ft = 1059 ft

The maximum height attained by the projectile is 1059 feet.

Answer:

(-1, 4)

Step-by-step explanation:

Original position of the ladybug → (-1, 4)

Animator rotates the ladybug 180° around the mushroom A.

Coordinates of the new position of the ladybug → (-5, -4)

Now this point is rotated by 180° around the mushroom B,

Coordinates of the new position → (0, 3)

Point (0, 3) has been rotated again by 180° about the mushroom C,

Coordinates of the new position → (-1, 4)

Therefore, ladybug will come back to its original position after these transformations at (-1, 4).

Alternate interior angles - <4 & <6

Vertical angles - <5 & <7

Alternate exterior angles - <1 &<7

Supplementary angles - <6 & <7

Corresponding angles - <8 & <4

Consecutive interior angles - <3 & <6

You set up was almost accurate. Remember the arc length formula:

If f'(y) is continuous on the interval [a,b], then the length of the curve x = f(y), a ≤ y ≤ b should be;

L = ∫ᵇ ₐ √1 + [f'(y)]^2 * dy

We have to find the length of the curve given x = √y - 2y, and 1 ≤ y ≤ 4. You can tell your limits would be 1 to 4, and you are right on that part. But f'(y) would be rather...

f'(y) = 1/(2√y) - 2

So the integral would be:

∫⁴₁ √1 + (1/(2√y) - 2)² dy

Using a calculator we would receive the solution 5.832. Their is a definite curve, as represented below;

Answer:

s = ∫₁⁴ √(1 + (1/(2√y) − 2)²) dy

s = 5.8319

Step-by-step explanation:

Arc length is:

s = ∫ ds

s = ∫ √(1 + (dx/dy)²) dy

Find dx/dy:

x = √y − 2y

dx/dy = 1/(2√y) − 2

Substitute:

s = ∫₁⁴ √(1 + (1/(2√y) − 2)²) dy

Evaluate with a calculator:

s = 5.8319

Answer:

[tex]\frac{9}{10}[/tex] ÷ [tex]\frac{5}{10}[/tex] = 1.8 / [tex]\frac{9}{5}[/tex] (or 1 [tex]\frac{4}{5}[/tex])

Step-by-step explanation:

when you convert these fractions to decimals, you get 0.9 and 0.5. then multiply them. the answer is 1.8 as a decimal, 9/5 as a fraction, or 1 4/5 as a mixed number.

ur mom ;),its 1.8, just delete it i swear :D

Answer:

y = x + 5

Step-by-step explanation:

We can take away the absolute value signs (as the equation does not differ with or without them).

To graph, one must remember slope-intercept form (y = mx + b)

M is the slope. When a clear "m" is not present, then one must assume that it is one, as the product of one and x is x.

B is where the y-axis intercepts the line (when x equals zero, y equals b). This is called the y-intercept. In this equation, b is five, so one point on the line is (0, 5). Then, following the slope (which is rise over run, or y over x), one must go up one, over one, up one, over one (up one unit, then to the right one unit (then mark your spot as a point)), then, draw a straight line connecting the two or more points. And there you have it!

Answer:

1: 36° 2: 122° 3: 122° 4: 38°

Step-by-step explanation:

First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.

Answer:

15965

Step-by-step explanation:

a=18395

d= -270 (lost inhabitants every year)

n=10

tn=?

We know that,

tn= a+(n-1)×d

=18395+(10-1)×(-270)

=18395+9×(-270)

= 18395 -2430

=15965

Hence,the present population of small town is 15965.

Step-by-step explanation:

a.

mean = E(X)

= no = 15 x 0.3

= 4.5

Standard deviation

= √np(1-p)

= √15x0.3x0.7

= √3.15

= 1.775

B.

Probability of number of buyers who want new copy

P(x>mean+2sd)

= P(x>4.5+2(1.775))

P(x>8.05)

= 1-(0.984757474+0.004747562)

= 0.01049

= 0.0105

C.

Σ13 (15Cx) x (0.3^x)(0.7)^15-x

= 0.9647

D. (4.5*237)+(15-4.5)*67

= 616.5+703.5

= $1320

Expected revenue from sale of next 15 copies is $1320

Answer:

The change should Sara receive from the $10 bill is $3.56.

Step-by-step explanation:

Given:

The table shows the prices of some breakfast items at a restaurant.

Item                                      Price

One egg                               $1.69

Slice of bacon                      $1.49

Glass of orange juice          

$1.09

Sara ordered 2 eggs, a slice of bacon, and  a glass of orange juice for breakfast.

The sales tax for the order was $0.48.

She paid for her breakfast with a  $10 bill.

Now, to find the change should Sara receive from the $10 bill.

Bill for the Sara's breakfast:

2 eggs =

A slice of bacon = $1.49.

A glass of orange = $1.09.

The sales tax = $0.48.

Total bill =

Sara paid for the breakfast bill = $10.

Now, to get the change Sara should receive we subtract the amount of bill from the money Sara paid for the bill:

Therefore, the change should Sara receive from the $10 bill is $3.56.

Answer:

Her change would be 3 dollars and 56 cents

Step-by-step explanation:

1.69 times 2 because she ordered 2 eggs

1.49 for the bacon

1.09 for the orange juice

0.48 for the sales tax

add them all up

it would equal 6.44

then subtract 6.44 from 10 which would equal 3.56

Answer:

5l.5

Step-by-step explanation: 412 divieded into 8 is 51 or 51.5

Answer:

51

Step-by-step explanation:

To find how many centerpieces she can make, divide 412 by 8, since she has 412 flowers and uses 8 for each one:

412/8

= 51.5

Since centerpieces can only be whole numbers in the real world, this has to be rounded down to 51.

So, she can make 51 centerpieces.
