Answer:

2nd option

y > 6 and y < 2

Step-by-step explanation:

as the value of y can not be greater than 6 and less than 2 at the same time, the 2 inequalities have no common solutions

theefore no solution

Answer:

512x−2+8=18

Step 1: Simplify both sides of the equation.

512x−2+8=18

512x+−2+8=18

(512x)+(−2+8)=18(Combine Like Terms)

512x+6=18

512x+6=18

Step 2: Subtract 6 from both sides.

512x+6−6=18−6

512x=12

Step 3: Divide both sides by 512.

512x512=12/512

x= 3/128

Answer:

x=3/128

Answer:

=> x = 8.33 oz weight of the first mixture therefore weight of the second mixture would be:

x+25= 8.33+25=33.33 oz

Step-by-step explanation:

We want to find the weight of each mixture which are unknown to us right now, therefore:

Let the weight of the first mixture be x. Then the weight of the second mixture would be (x+25) and the weight of final mixture would be (x + x + 25) = 2x+25.

The first mixture had 30% pecans, therefore the weight of pecans from the first mixture would be 0.3x.

The second mixture had 40% pecans, therefore the weight of pecans from the second mixture would be 0.4 * (x+25).

We will have 38% pecans in the final mixture hence the weight of pecans is 0.38 of the total weight of pecans in the final mixture.

0.38 * (2x + 25)

Therefore

0.38 * (2x + 25) = 0.3x + 0.4*(x + 25).

Now we have one equation one unknown and solve for x:

=> 0.76x + 9.5 = 0.7x + 10

=> 0.76x - 0.7x = 10 - 9.5

=> 0.06x = 0.5

=> x = 50/0.06

=> x = 50/6 = 25/3

=> x = 8.33 oz weight of the first mixture therefore weight of the second mixture would be:

x+25= 8.33+25=33.33 oz

Answer:

10 combinations

Step-by-step explanation:

Given

[tex]n = 5[/tex] --- total production

[tex]r = 3[/tex] --- aircraft to select

Required

The total number of combination

The number of combination is calculated using:

[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]

So, we have:

[tex]^5C_3 = \frac{5!}{(5 - 3)!*3!}[/tex]

[tex]^5C_3 = \frac{5!}{2!*3!}[/tex]

Expand

[tex]^5C_3 = \frac{5*4*3!}{2*1*3!}[/tex]

[tex]^5C_3 = \frac{5*4}{2*1}[/tex]

[tex]^5C_3 = \frac{20}{2}[/tex]

[tex]^5C_3 = 10[/tex]

Answer:

a =55

b =16

c = 25

d = 9

Step-by-step explanation:

of means multiply  is means equals

20% of a is 11

.20 a = 11

Divide by .20

a = 11/.20

a=55

75% of b is 12

.75 b =12

Divide by .75

b = 12/.75

b = 16

80% of c  is 20

.80 c =20

Divide by .80

c = 20/.80

c =25

200% of d is 18

2.00 d = 18

Divide by 2.0

d = 18/2

d =9

Answer and Step-by-step explanation:

The answer is 2 (which is equal to x).

If you were to plug 2 in to the function, the result if 30.

Answer:

w = 5

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w)

28 = 2(2w-1 + w)

Combine like terms

28 =2(3w-1)

Divide each side by 2

28/2 = 2/2(3w-1)

14 = 3w-1

Add 1 to each side

14+1 = 3w-1+1

15 = 3w

Divide each side by 3

15/3 =3w/3

5 =w

Answer:

C, 14

Step-by-step explanation:

The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 98 are: 1, 2, 7, 14, 49, 98

Then the greatest common factor is 14. (The greatest factor that they all have in common.)

Answer:

The probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Step-by-step explanation:

Step 1:

The probability that, in successive drawing of chips, the colors of the first four chips alternate, can occur in two ways: RED-WHITE-RED-WHITE (RWRW) or WHITE-RED-WHITE-RED (WRWR).

Step 2:

Given that an urn contains three white and four red chips and that each time we draw a chip, we look at its color. If it is red, we replace it along with two new red chips, and if it is white, we replace it along with three new white chips.

Probability of RWRW is given as follows:

Probabilty of the first being a red = 4/7

Probability of the next being a white = 3/9 = 1/3

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/14 = 3/7

Thus, probability of RWRW = 4/7 × 1/3 × 1/2 × 3/7 = 0.0408

Probability of WRWR is given as follows:

Probabilty of the first being a white = 3/7

Probability of the next being a white = 4/10 =2/5

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/15 = 2/5

Thus, probability of WRWR = 3/7 × 2/5 × 1/2 × 2/5 = 0.0343

Step 3:

Probability of RWRW or WRWR = 0.0408 + 0.0343 = 0.0751

Therefore, the probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Answer:

B.

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Answer:

y = - x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (9, 0) ← 2 points on the line

m = [tex]\frac{0-9}{9-0}[/tex] = [tex]\frac{-9}{9}[/tex] = - 1

The line crosses the y- axis at (0, 9 ) ⇒ c = 9

y = - x + 9 ← equation of line

Answer:

20 cashiers

Step-by-step explanation:

There is 10 boxes. Each cashier is given 1/2 of one box.

10 multiplied by 2 (which is 20) gives you the amount of cashiers since each one is given one half and there is 20 one halfs in 10.

Answer:

V = 29.31 cm^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

V = 1/3 (3.14) (2)^2 (7)

V =29.30666

Rounding to the nearest hundredth

V = 29.31 cm^3

Answer:

Tn=a(-3)^(n-1)

Step-by-step explanation:

r=-3

Answer:

Step-by-step explanation:

20% = 20/100 = 0.2

The amount you need to pay for a T shirt is

Cost = original amount(100% - 20%)

Original amount = 18

100% - 20% = 80%

80% = 80 / 100 = 0.8

What this means is that you will pay 80% of  the original cost.

Cost = 18*0.8

Cost = $14.40

Part B

Cost = 0.8 * x

Part C

Selling price = 0.8*Original Cost

Selling price = 18

18 = 0.8 * x

18/0.8 = x

x = 22.5

The original price was $22.50

Answer:

17 cm

Step-by-step explanation:

Rectangle perimeter: length*2 + width*2

Substitute width with "x".

Length is given as 15 cm

Perimeter is given as 64 cm

Plug in the values and solve for x.

64 = 2*15 + 2x

64 = 30+2x

2x = 34

x = 17

so width is 17 cm
