r = 10.7

The probability of drawing a two and another 2 is 1/72

Probability is the likelihood or chance that an event will occur

Pr(drawing a 2, then drawing another 2) = 1/72

Hence the probability of drawing a two and another 2 is 1/72

Answer:

$27.17

Step-by-step explanation:

Regular price of necklace = $44

If a discount of 35% is applied, then the new price of the necklace will be 65% of the regular price, as 100% - 35% = 65%

⇒ 65% of $44

= 0.65 × $44

= $28.60

If a second discount of 5% is then applied, the final price of the necklace will be 95% of the sale price, as 100% - 5% = 95%

⇒ 95% of $28.60

= 0.95 × $28.60

= $27.17

Therefore:

The sale price with a 35% discount is $28.60

The sale price with an additional 5% discount is $27.17

[tex]\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}[/tex]

Given :-

The regular price of necklace = $44

Discount on necklace = 35%

Additional save from necklace = 5%

Solution :-

First we have to found the prize of necklace that Amantha had bought at 35% discount

To find this, there is a formula

[tex]new \: price = real \: price - (discount \: percentage \times real \: price) [/tex]

Now we will put our value in this formula

[tex] = 44 - ( \frac{35}{100} \times 44) \\ = 44 - ( \frac{7}{20} \times 44) \\ = 44 - ( \frac{7}{10} \times 22) \\ = 44 - \frac{154}{10} \\ = 44 - 15.4 \\ = 28.6 \:[/tex]

Now will deduct the additional discount from this price by using same formula

[tex] = 28.6 - ( \frac{5}{100} \times 28.6) \\ = 28.6 - ( \frac{1}{20} \times \frac{286}{10} ) \\ = 28.6 - ( \frac{1}{10} \times \frac{143}{10} ) \\ = 28.6 - 1.43 \\ = 27.17[/tex]

Result :-

She spend $27.17 on buying the necklace

Answer: 76.8 mi²

Step-by-step explanation:

   The area of a parallelogram can be found be multiplying the base times the height.

       A = B * H

       A = 9.6 * 8

       A = 76.8 mi²

   Confused as to why this works? We use the same formula that we do for a rectangle because the "extra triangle" on the left can be moved to fill the empty space on the right. This then gives us a normal rectangle, which allows us to solve for the area

In this question we are provided with the base and height of a parallelogram and we are asked to calculate the area of the parallelogram using the formula.

It is given that the base is 9.6 mi and height is 8 mi.

We know,

[tex] \small\boxed{ \sf {Area_{(parallelogram)} = B × H}}[/tex]

Where,

Substituting the values we get

[tex] \small\sf{ Area_{(parallelogram)} = (9.6 × 8) mi} = 76.8 {mi}^{2} [/tex]

The annuity of the monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years is $333.71

An annuity is a series of payments made at equal period of time.

future value = annuity x [(1 + i)ⁿ - 1] / i

annuity = $125.30

i = 1.5% / 12 = 0.00125

n = 35 years x 12 months = 420

future value = $125.30 x [(1 + 0.00125)⁴²⁰ - 1] / 0.00125

future value = $69,156.049 ≈ $69,156.05

annuity = [i x (present value)] / [1 - (1 + i)⁻ⁿ]

i = 1.5% / 12 = 0.00125

n = 20 years x 12 months = 240

present value = $69,156.05

annuity = (0.00125 x $69,156.05) / [1 - (1 + 0.00125)⁻²⁴⁰]

annuity = $86.45 / 0.25904

= $333.71

x = [tex]-\frac{1}{2}a-\frac{1}{4}b+\frac{9}{4}[/tex]

Step-by-step explanation:

We will see that the number of different combinations for each case are:

We have 5 selections for each password, we need to find the number of options for each one of these selections.

a) Here we can use only capitals an we can repeat, so for each selection (each letter), we have 26 options.

The total number of combinations will be equal to the product between the numbers of options:

C = 26*26*26*26*26 = 11,881,376

b)Now we can use either capitals or lower case, but we can't repeat. (Here I assume that A is different than a, so we can't use A two times, but we could use A and a).

Then we have 26*2 = 52 options.

For the first letter, we have 52 options.

For the second letter, we have 51 options (because one letter was already used).

For the third letter, we have 50 options, and so on.

The total number of combinations will be:

C = 52*51*50*49*48 = 311,875,200

Answer:

Infinitely many solutions.

Step-by-step explanation:

Let's solve your system by substitution.

2x+3y=−6;4x+6y=−12

Step: Solve2x+3y=−6for x:

2x+3y=−6

2x+3y+−3y=−6+−3y(Add -3y to both sides)

2x=−3y−6

2x/2 = −3y−6/2

(Divide both sides by 2)

x= −3/2y−3

Step: Substitute −3/2y−3 for x in 4x+6y=−12:

4x+6y=−12 4(−3/2y−3)+6y=−12

−12=−12(Simplify both sides of the equation)

−12+12=−12+12(Add 12 to both sides)

Answer: 424.12

Step-by-step explanation:

Mr. Brust needs 427 cans to cover the wall of dimensions 20 feet long and 9 feet tall.

Area of rectangle is the product of its sides

i.e., Area of rectangle = length  x breadth

The area of a circle is pi times the radius squared (A = π r²).

The circumference of a circle is defined as the linear distance around it.

( C= 2πr)

The can of red bull is in shape of cylinder.

If we open the cylinder it will have two circular surfaces( at bottom and top) and one rectangular sheet.

Like the given figure given.

It shows that the two circle will have the diameter 2.5 inches.

d= 2.5 inch

 = 0.208 ft

radius, r= [tex]\frac{d}{2}[/tex]

r= [tex]\frac{0.208}{2}[/tex]

r= 0.104 ft

Circumference of the circle be,

= 2πr

= 2 x 3.14 x 0.104

= 0.653 ft

The rectangular sheet will have,

length=  0.653 ft, breadth= 6.5 inches = 0.541 ft

      = length x breadth

      = 0.653 x 0.541

      =[tex]0.3532 ft^{2}[/tex]

       = 2 x π[tex]r^{2}[/tex]

       = 2 x 3.14 x 0.104 x 0.104

       = 6.28 x 0.010816

       = 0.0679 [tex]ft^{2}[/tex]

        = Area of rectangular sheet + Area of 2 circle( top and bottom of can)

        = 0.3532 + 0.0679

        = 0.4211 [tex]ft^{2}[/tex]

Now, we have the wall of dimensions

length= 9 ft, breadth= 20 ft

= length x breadth

=9 x 20

= 180 [tex]ft^{2}[/tex]

         =[tex]\frac{area \;of\; wall}{area \;of\; can}[/tex]

         =[tex]\frac{180}{0.4211}[/tex]

Answer:

27°

Step-by-step explanation:

Answer:

∠OAC = 27°

Step-by-step explanation:

The radius of the circle is perpendicular to the tangent line.

Therefore, ∠ACO = 90°

The interior angles of a triangle sum to 180°

⇒ ∠OAC + ∠ACO ∠ COA = 180°

⇒ ∠OAC + 90° + 63° = 180°

⇒ ∠OAC + 153° = 180°

⇒ ∠OAC = 180° - 153°

⇒ ∠OAC = 27°

The volume of a cone with diameter d (and hence radius d/2) and height h is

The volume of a cylinder with base diameter d and height h is

[tex]V_{\rm cylinder} = \pi\left(\dfrac d2\right)^2 h[/tex]
