Area of a circle D=10
a.62.80
b.78.50
c.314
d.15.70
e.31.40

Answer:

  15/16

Step-by-step explanation:

For the purpose here, we define a starting value as the midpoint of the interval between the integers on either side of the solution. Those integers are 0 and 1, so our starting value for an approximation of x is 1/2.

Each iteration will evaluate the difference f(x)-g(x) at this approximation. If the difference has the sign that matches the difference at the left end of the interval, then the approximation replaces the left end. If the sign matches the difference at the right end, then the approximation replaces the right end. The iteration ends with an approximation that is the midpoint of the new interval.

The attachment shows that our intervals start at [0, 1] and proceed through [1/2, 1], [3/4, 1] to [7/8, 1]. The approximation at the end of the 3rd iteration is x ≈ 15/16.

Additional comment

The way this iterative process is defined, the denominator of the n-th approximation will be 2^(n+1). That is, the third iteration will result in a fraction with a denominator of 2^(3+1) = 2^4 = 16, as in 15/16.

Answer:

  30

Step-by-step explanation:

Let d represent the number of dozens of golf balls ordered. Then 12d is the number of balls.

The cost of the Light Hit balls will be (2.00)(12d). The cost of the Pro Sport balls will be (0.90)(12d). The difference in cost is ...

  (2.00)(12d) -(0.90)(12d) = 396.00

  1.10d = 33 . . . . . divide by 12, combine terms

  d = 30 . . . . . . . divide by 1.10

30 dozen balls of each brand were ordered.

2(w - 6) > -15

Step-by-step explanation:

2(w - 6) > -15

⇒ 2w - 12 > -15

⇒ 2w > -3

⇒ w > -3/2

Answer:

D

Step-by-step explanation:

1. Add the costs together 10.98+13.95+22.56=47.49

2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.

47.49/3=15.83

The option closest to our number is D so we round up.

$15.83->$20

Have a good day.

Answer:

C

Step-by-step explanation:

H = [tex]cos^{-1} (\frac{1}{8} )[/tex]

H = 82.82°

angle J:

cosJ = [tex]\frac{8^2+12^2-10^2}{2*8*12}[/tex]

J = [tex]cos^{-1}(\frac{9}{16} )[/tex]

J = 55.77°

ANSWER-

Answer:

a)

b) 1/3

c) 1/2

d) 1/2

e) 0

Step-by-step explanation:

a) There are 2 different types of dessert and 3 different ice cream flavors.      

   Therefore, there are 6 possible ice cream orders:

b) There are 2 different desserts with apricot ice cream.

⇒ P(apricot ice cream) = 2/6 = 1/3

c) There are 3 combinations of sundae.

⇒ P(sundae) = 3/6 = 1/2

d) P(chocolate) = 2/6 = 1/3

   P(blackberry waffle cone) = 1/6

⇒ P(choc) OR P(BWC) = 1/3 + 1/6 = 1/2

e) P(orange sherbet) = 0

Answer:

  the correct choice is marked

Step-by-step explanation:

The tip is 20% of the bill:

  20% × $124.00 = $24.80

When that is added to the bill, the total is ...

  $124.00 +24.80 = $148.80

Answer:

A.

Step-by-step explanation:

You need to find 20% of the order to find the tip then add that to the original bill.

So, you need to solve 124x0.20 to get 24.80. That's the tip.

Next, add 124+24.80=148.80. There is your answer.

Hope you get an A! <3

31.5 <---- Ans

Answer:

31.5

Step-by-step explanation

If you divide something by 10 you move the decimal over one place to the left.

315.0 / 10 = 31.5

It would be 13.3 years till the mass of the sample reached 24 grams.

'A quantity is subject to exponentially decay if it decreases at a rate proportional to its current value.'

According to the given problem,

Let x be the number of years spent,

Initial mass = 40 grams

Final mass = 24 grams

Half-life = 18 years

⇒ 24 = 40 × [tex]0.5^{\frac{x}{18} }[/tex]

⇒ 24/40 = 0.5^[tex]\frac{x}{18}[/tex]

⇒ 3/5 = 0.5^[tex]\frac{x}{18}[/tex]

Taking ln on both sides,

⇒ ln (3/5) = [tex]\frac{x}{18}[/tex] ln 0.5

⇒ ln (3/5) / ln (0.5) = x/18

⇒ x = ( 18 × ln (3/5) ) / ln (0.5)

⇒ x = 13.3 years

Hence, we can conclude that the sample need s 13.3 years to decrease its mass from 40 grams to 24 grams.

The maximum area that David can have is  10,000 yd^2

The formula for calculating the area of a rectangle is expressed as:

A = lw

If David has 400 yards of fencing, then;

P = 2(l +w)

400 = 2( l+ w)

200 = l + w

l = 200 - w

Substitute into the area

A = (200-w)w

A = 200w - w^2

If the area is maximized, then;

dA/dw = 0
dA/dw = 200 - 2w

2w =200

w =  100 yards

Recall that;

200 = l + w

l = 200 - 100

l = 100

The maximum area = 100 * 100

The maximum area = 10,000 yd^2

The maximum area that David can have is  10,000 yd^2

Answer:

.53

Step-by-step explanation:

divide 8 by 15 and you get 0.53 explanation As a decimal 8/15 is 0.533 (3 repeating) or about 0.53. To convert 8/15 into a decimal value we simply divide 8 by 15. Since 15 cannot be divided into 8 we add a decimal and a zero then divide 15 into 8, giving us 5 with 5 remaining. Adding another zero allows us to divide 15 into 50 3-times with 5 remaining.

The number of comedy DVDs will be equal to 604.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the total number of DVDs are 1830 and the percentage of comedy DVDs is 33%.

The number of comedy DVDs will be calculated as,

N = ( 1830 x 33%)

N = (1830 x 33 ) / 100

N = 604

Therefore, the number of comedy DVDs will be equal to 604.

Answer:

750

Step-by-step explanation:

Given:

discount of 25%

Hasan's equation:  d - 0.25d

Bella's equation: 0.75d

d represents the original price.

0.25d represents the discount.

0.75d represents the discounted price.

Example: 1,000 is the price. d = 1,000

0.25d = 0.25(1000) = 250 this is the discount

0.75d = 0.75(1000) = 750 this is the discounted price

Hassan: d - 0.25d =  1000 - 250 = 750

Bella: 0.75d = 0.75(1000) = 750

Answer:

a) The temperature of the water at 5 p.m. would be below 0

b) The temperature of the water at 5 p.m. would be -2.5 *C

Step-by-step explanation:

A) Adding-10.6 and -8.7 would give you over 19, and this would be more than 16.8. Therefore, we can assume that 16.8- 19 is less than zero

B) -10.6+16.8-8.7=-2.5

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20.
