David made $216 for 12 hours of work. At the same rate, how many hours would he have to work to make $306?

Answer:

Yes; P(blue glove) = 11/20 and P(not blue glove) = 9/20

The probability of selecting a blue glove is greater than the probability of not choosing a blue glove.

See the attached diagram below

==============================================

Explanation:

There are 3 red gloves, 6 black gloves, and 11 blue gloves. So there are 3+6+11 = 20 gloves total in the drawer. The probability of picking blue is 11/20. The probability of not picking blue is 9/20 since we had 3red+6black = 9 gloves that are not blue. Or you could note that 11/20 + 9/20 = 20/20 = 1.

------------------

The probability of picking blue is greater than the probability of not picking blue. Oliver is likely to pick a second blue glove.

The way to see how 11/20 is larger than 9/20 is to compare the numerators. We see that 11 > 9, so that helps show 11/20 > 9/20.

You could also use your calculator to look at the decimal form of each fraction

11/20 = 0.55

9/20 = 0.45

This shows 11/20 is larger.

Step-by-step explanation:

Since cotθ = (cosθ/sinθ)

(cotθ)(sinθ) = (cosθ/sinθ)(sinθ) = cosθ. (A)

Answer:

750 would be ur answer

Step-by-step explanation:

happy new year!

Answer:750 desks

Step-by-step explanation: I would start by setting up an equation. 5d=250 (d means days). Then, to isolate the d, I would divide both sides of the equation by 5. I would get d=50. So there are 50 desks made daily. To find out the number of desks made in 15 days, I would just multiply both sides of the equation d=50 by 15 and I would get 15d=750. That means, there are 750 desks produced in 15 days. I hope this helps you out a bit!

Answer:

-2/9

Step-by-step explanation:

Taking the reciprocal of anything just means to flip the fraction.

In this case, we are given -9/2.

Flipping the numerator and denominator gives us -2/9.

Answer:

θ = 85.93° (≈ 86°)

Step-by-step explanation:

arc length : 2πr = θ : 360°

7.5 : 2πr = θ : 360°

θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°

θ ≈ 86°

Answer:

k = 4

Step-by-step explanation:

3k - 2 = 10

3k - 2 + 2 = 10 + 2     (adding 2 to both sides)

           3k = 12

        3k/3 = 12/3       (dividing both sides by 3)

             k = 4

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

3x-12

1)

Writing the expression in an equivalent form

3x-12

Factor out common term 3

3x-12 = 3(x-4)

Thus, 3(x-4) is equivalent to 3x-12.

2)

Writing the expression in an equivalent form

3x-12

Multiply the expression by 2/2

[tex]3x-12\:=\frac{2}{2}\:\times \:\left[3x-12\right][/tex]

Therefore, [tex]\frac{2}{2}\:\times \:\left[3x-12\right][/tex] is equivalent to 3x-12.

Answer:

1/2 cup of milk

Step-by-step explanation:

Given

Total cup of milk needed = 3/4 cup of milk

Amount she has = 1/4 cup of milk

The amount of milk she needed = Total - Amount she has

Amount she needed = 3/4 - 1/4

Amount she needed = (3-1)/4

Amount she needed = 2/4

Amount she needed = 1/2

Hence she needs 1/2 cup of milk more

Answer:

304

Step by step:

Using your calculator 5% of 320 is 16.

Since it was a discount, you subtract 16 since you're marking it down.

320-16=304

304 is your answer

How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320

Answer:

$304.00

that is really freaking expensive shirt lol.

i thought you said shlt,  not shirt lol

anyway...

Step-by-step explanation:

320 times 0.05

(don't make the mistake of 0.5  that is 50%, not 5%. )

320*0.05= 16

subtract it

320-16= 304

Pulling out like terms

4.1 Simplify ( -2xy3z-2 )3

Put the exponent aside and simplfy the base by pulling out like factors :

-2xy3z-2 = -2 • (xy3z+1)

Remember the 4th law of exponents : (a • b)m= am• bm

Retract the exponent and apply the 4th law to the simplified base: ( -2 • (xy3z+1) )3 = (-2)3 • (xy3z+1)3

Trying to factor as a Sum of Cubes:

4.2 Factoring: xy3z+1

Put the exponent aside, try to factor xy3z+1

Theory : A sum of two perfect cubes, a3 + b3 can be factored into :

(a+b) • (a2-ab+b2)

Proof : (a+b) • (a2-ab+b2) =

a3-a2b+ab2+ba2-b2a+b3 =

a3+(a2b-ba2)+(ab2-b2a)+b3=

a3+0+0+b3=

a3+b3

Check : 1 is the cube of 1

Check : x 1 is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Dividing exponents:

4.3 23 divided by 22 = 2(3 - 2) = 21 = 2

Final result :

The system of equations has no solution.

NO SOLUTION!

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}y=-\frac{1}{2}x+4\\ x+2y=-8\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y+\frac{1}{2}x=4\\ 2y+x=-8\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y+\frac{1}{2}x=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+x=8[/tex]

[tex]\begin{bmatrix}2y+x=8\\ 2y+x=-8\end{bmatrix}[/tex]

subtracting equation 2y+x=8 from 2y+x = -8

[tex]2y+x=-8[/tex]

[tex]-[/tex]

[tex]\underline{2y+x=8}[/tex]

[tex]0=-16[/tex]

so the equations become

[tex]\begin{bmatrix}2y+x=8\\ 0=-16\end{bmatrix}[/tex]

0 = -16 is false, therefore the system of equations has no solution.

Answer:30 x 96 feet = 10 x 32 yards

Step-by-step explanation:Convert 30 x 96 feet to yards

To convert length x width dimensions from feet to yards we should multiply each amount by the conversion factor. One foot equals 0.333333 yards, in order to convert 30 x 96 feet to yards we have to multiply each amount of feet by 0.333333 to obtain the length and width in yards. In this case to convert 30 x 96 feet into yards we should multiply the length which is 30 by 0.333333 and the width which is 96 by 0.333333. The result is the following:

30 x 96 feet = 10 x 32 yards

Definition of foot

A foot (symbol: ft) is a unit of length. It is equal to 0.3048 m, and used in the imperial system of units and United States customary units. The unit of foot derived from the human foot. It is subdivided into 12 inches.

Definition of yard

A yard (symbol: yd) is a basic unit of length which is commonly used in United States customary units, Imperial units and the former English units. It is equal to 3 feet or 36 inches, defined as 91.44 centimeters.

Meters to yards formula and conversion factor

To calculate a foot value to the corresponding value in yards, just multiply the quantity in feet by 0.333333 (the conversion factor).

Meters to yards formulae

yards = feet * 0.333333

The factor 0.333333 is the result from the division 1 / 3 (yard definition). Therefore, another way would be:

yards = feet / 3

Using our feet to yards converter you can get answers to questions like:

- How many yards are in 30 x 96 feet?

- 30 x 96 feet is equal to how many yards?

- How to convert 30 x 96 feet to yards?

- What is 30 x 96 feet in yards?

- How many is 30 x 96 feet in yards?

Answer:

The area of the room is 432 square feet

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The scale drawing of the room is 1 inch: 3 feet

→ That means each 1 inch in the drawing represents 3 feet in real

∵ The drawing is 8 inches long by 6 inches wide

∴ The drawing length of the room = 8 inches

∴ The drawing width of the room = 6 inches

→ By using the ratio method

→  inches  :  feet

→  1            :  3

→  8           :  L

→  6           :  W

→ By using the cross multiplication

∵ 1 × L = 8 × 3

∴ L = 24

∴ The actual length of the room is 24 feet

∵ 1 × W = 6 × 3

∴ W = 18

∴ The actual width of the room is 18 feet

Use the formula of the area of the rectangle to find the area of the room

∵ Area of rectangle = length × width

∴ Area of the room = 24 × 18

∴ Area of the room = 432 feet²

∴ The area of the room is 432 square feet
