[tex]\frac{1}{4}[/tex]

= 0.25

Step-by-step explanation:

In a standard deck of cards, there are 52 cards. The standard deck of cards also has 13 clubs. Probability is;

[tex]\frac{wanted- outcomes}{total- outcomes}[/tex]

The wanted outcomes is a clubs, the total outcomes are the total number of cards in the deck, hence;

[tex]\frac{13}{52}[/tex]

Simplify;

[tex]\frac{1}{4}[/tex]

Answer:

The maximum revenue Luci can make selling cookies in one day is $4,004,000.

Step-by-step explanation:

Given;

x = −2000 p + 4000 ..................... (1)

Revenue = xp

Revenue = (−2000 p + 4000)p =

Revenue = −2000p^2 + 4000p .................... (2)

The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:

−4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

This implies that the price at which Luci will the maximum profit is $1.

Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:

Revenue = (−2000 * 1)^2 + (4000 * 1)

Revenue =  −2000^2 + 4000

Revenue = 4,000,000 + 4000

Revenue = 4,004,000

Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

Answer:

14.77 feet

Step-by-step explanation:

Using the pythagoras theorem to get the length of the ramp

l² = 13² + 7²

l is the length of the ramp

l² = 169 + 49

l² = 218

l = √218

l = 14.77 feet

Hence the length of the ram is 14.77 feet

Answer:

RT = 20

Step-by-step explanation:

Point S is on line segment

R------------S------------T

RS + ST = RT

Given

ST=3x-8

RT=4x

RS=4x-7,

Step 1

We find x

4x - 7 + 3x - 8 = 4x

4x + 3x -7 - 8 = 4x

7x - 15 = 4x

7x - 4x = 15

3x = 15

x = 15/3

x = 5

Step 2

We find RT

RT = 4x

x = 5

RT = 4 × 5

RT = 20

The numerical length of RT is 20

Answer:

The first number is zero, and the second number is 17

Step-by-step explanation:

If we triple the first number (which is zero), it would still equal zero. Then, if you double the second number the answer would be 34.

have a good day!! :)

Answer:

Area of original = 169m^2

Area of new = 676m^2

Step-by-step explanation:

Area of a square = (length of side)^2

13^2 = 13 * 13 = 169

If the dimension is doubled:

(2*13)^2 = 26^2 = 676

Step-by-step explanation:

Step-by-step explanation:

Soln

given,

from the figure

coordinate of B is (5,3),

A(7,0) and C(0,4)

A. solution

let, M(x,y) be the mid point of AB

A(7,0) = (x1,y1)

B(5,3) = (x2,y2)

we know

x = (x2+x1)/2

or, x = (5+7)/2

or, x = 12/2

or, x = 6

and for y

y = (y2+y1)/2

or, y = (3+0)/2

or, y = 3/2

therefore M(x,y) = (6,3/2)

B. solution

let,

C(0,4) = (x1,y1)

B(5,3) = (x2,y2)

equation of line is ;

(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)

or, (y - 4)/(x -0) = (3 - 4)/(5 - 0)

or, (y - 4)/(x - 0) = -1 / 5

by cross multiply

or, 5×(y - 4) = -1×(x)

or, 5y - 20 = -x

or, x + 5y = 20 is the required equation.

Answer:

Step-by-step explanation:

I will REALLY answer your question :)

9.5 = 25/t + -8

The first step here is to simplify t + -8. If you add a negative of  something, you also subtract. This can be rewritten as:

9.5 = 25/t - 8

Now, we need to add 8 to undo the subtraction.

17.5 = 25/t

Now, to undo the division, we will multiply the whole equation by 25.

17.5 x 25 = 437.5

Answer:

180 - 46 - 83 = 51 is the measure of angle C

the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.
