Answer:

The number of different platters Selena can create by selecting two different vegetables is 60 different platters

Step-by-step explanation:

The information given are;

The number of different sizes of salad available = 4

The number of different vegetable to choose from = 6

The number of vegetables Selena ordered = 2

The number of ways Selena can choose 2 vegetables out of 6 = ₆C₂ = 15 ways

The number of different platters (choice of vegetable and size of platter) Selena can create = The number of different sizes of salad available × The number of ways Selena can choose the vegetables

The number of different platters (choice of vegetable and size of platter) Selena can create = 4 × 15 = 60 different platters.

Answer:

£60

Step-by-step explanation:

Let the original cost be x.

x × (1 - 20%) = 48

0.8x = 48

x = 48/0.8

x = 60

The original cost was £60 before the sale.

Answer:

£57.60

Step-by-step explanation:

find 20% of £48, which is £9.60

then add that to £48, which will give you the answer of £57.60

Answer:

561

Step-by-step explanation:

an = dn - (a-d)

The difference is 3.

The first term is 12.

an = 3n - (12-3)

an = 3n - 9

Put n as 1, 2, 3, 4, 5 ....22.

3(1) - 9 = -6

3(2) - 9 = -3

3(3) - 9 = 0

3(4) - 9 = 3

3(5) - 9 = 6

...

3(22) - 9 = 57

Add the first 22 terms.

-6+-3+0+3+6+9+12+15+18+21+24+27+30+33+36+39+42+45+48+51+54+57

Answer:

[tex]144\pi in^2[/tex]

Step-by-step explanation:

Given

Shape: Circe

Radius = 6 inches

Required

What is the surface area of a sphere when the circle

When a circle is rotated about its diameter, the resulting sphere maintains the same radius and diameter as the circle, before rotation;

This implies that

Radius [of sphere] = 6 inches

[tex]Surfare\ Area = 4\pi r^2[/tex]

Substitute 6 for r

[tex]Surfare\ Area = 4\pi* 6^2[/tex]

[tex]Surfare\ Area = 4\pi* 6 * 6[/tex]

[tex]Surfare\ Area = 4\pi*36[/tex]

[tex]Surfare\ Area = 144\pi[/tex]

Hence, the surface area of the resulting sphere is 144 pi inches square

Answer:

Together they rock chairs 60 times per minute. 1020/60=17 So it will take 17 min

The number of minutes that the check 1,020 rock chairs will be 17 minutes.

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

If Mr. Gillespie can rock a chair 28 times per minute, and Mr. Matheson can rock a chair 32 times per minute.

Let 'x' be the number of minutes and 'y' be the total chair that they check together. Then the equation is given as,

28x + 32x = y

60x = y

The number of minutes that the check 1,020 chairs will be given as,

60x = 1,020

x = 1,020 / 60

x = 17

The number of minutes that the check 1,020 rock chairs will be 17 minutes.

Answer:  a) 110√2 meters

                b) 2.42 hectares

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

An experimental probability is the number of times an event occurred when actually attempted.

So, if Jo does the experiment 60 times and receives 50 unpainted balls, then calculate how many painted balls she got:

60-50 = 10.

So, the probability of picking a painted ball = 10/60 = 1/6

Answer:

7640 Students are Girls

Step-by-step explanation:

10% of all students is 1,910

We know 60% is male so we do 1910 x 6 = 11460

Now we take the total - the amount of guys

19,100 - 11460 = 7640

40% is female = 7,640

Answer:

45%

40 yellow chips

Step-by-step explanation:

Total chips: 9 + 11 = 20

P(Male) = 9/20 × 100 = 45%

60% of 100

60/100 × 100

60 red

100 - 60 = 40 yellow chips

Answer: $70 per hour

Step-by-step explanation:

Hi, to answer this question we have to calculate the hourly fee.

To do this, we simply have to divide the 5 hour fee price (350) by the number of hours worked.(5):

Mathematically speaking:

350/5 = $70 per hour

So, since the work fee is proportional, for x hours, the expression is:

70x

Answer:

A = 4, B = 3, C = 7, D = 6

Step-by-step explanation:

A = 4 because A represents the number of people who didn't visit either place. This means that B + C + D = 20 - 4 = 16. To find C, which is the overlap we can do 10 + 13 - 16 = 7 so C = 7 which means B = 10 - 7 = 3 and D = 13 - 7 = 6.

Answer:  proof below

Step-by-step explanation:

Use the Difference formula for sin:

  sin (A - B) = sin(A)·cos(B) - cos(A)·sin(B)

sin (180° - θ) = sin(180°)·cos(θ) - cos(180°)·sin(θ)

Step-by-step explanation:

Let x be the missing number

Answer: (-2,1)

Step-by-step explanation:

y=x+3  

y=2x+5  substitute  the y value in the first equation into the second equation

x+3 = 2x+5  now solve for x

   -3        -3

x = 2x +2   subtract 2x from both sides

-2x   -2x

-1x = 2       Divide both sides by -1

x= -2  

The value of x is -2 to plot it into one of the equations to solve for y.

y= -2 + 3

y = 1  

(-2,1)

Answer: x = − 2  and y = 1

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

/| y-x-3 = 0| y-(2*x)-5 = 0

We try to solve the equation: y-x-3 = 0

y-x-3 = 0 // + -x-3

y = -(-x-3)

y = x+3

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| x-(2*x)-5+3 = 0| y = x+3

-x-2 = 0 // + 2

-x = 2 // * -1

x = -2

We insert the solution into one of the initial equations of our system of equations

For y = x+3:  

y = 3-2

y = 1

We get a system of equations:

/| y = 1| x = -2

Hey there! :)

Answer:

m∠y = 55°.

Step-by-step explanation:

Begin by solving for x since y and x are supplementary angles.

Recall that all of the angles in a triangle must sum up to 180°. Therefore:

180 - 30 - 25 = 125°.

x = 125°, therefore:

180 - 125 = 55°.

m∠y = 55°.

Answer:

55 Degrees
