Answer:

c = 0.85 ; $1.7 ; c = 0.79p

Step-by-step explanation:

Given :

Cost per pound of supply shipped = $0.85

Total cost, c to ship p pounds of horse supply

Total cost = cost per pound * pound of supply

c = 0.85 * p

c = 0.85p

Cost of shipping 2 pounds :

c = 0.85 * 2

c = $1. 7

B.)

Reduction in shipping cost :

Reduced cost = $0.85 - $0.06 = $0.79

Total cost = cost per pound * pound of supply

c = 0.79 * p

c = 0.79p

Answer:

The percent of increase in the size of the sugar order is 75%.

Step-by-step explanation:

To find the percent of increase in the size of the sugar order, you can use the following formula:

% increase = ((New number-Original number) ÷ Original Number)x100

New number=13,510

Original number=7,720

Now, you can replace the values in the formula:

% increase = ((13,510-7,720) ÷ 7,720)x100

% increase = (5,790 ÷ 7,720)x100

% increase = 0.75x100

% increase = 75%

According to this, the answer is that the percent of increase in the size of the sugar order is 75%.

Answer:

105 degrees

Step-by-step explanation:

The angle of a straight line is 180 degrees. Since we need to find the angle for 3, it is 180-75 which is 105 degrees.

Answer:

n=-5

Step-by-step explanation:

You must multiply [tex]x^{-8}*x^{3}[/tex]. The laws of exponents state that when multiplying exponents of the same base, you can just add the exponents and raise the base to the sum of the exponents. So, [tex]x^{-8}*x^{3}=x^{(-8+3)}=x^{-5}[/tex].  Since our end product is [tex]x^{-5}[/tex], n is equal to -5.

Answer:

A total of 15 matches were played.

Step-by-step explanation:

To determine the number of matches that were played in the chess tournament, knowing that there are 16 participants who face each other in a tournament of direct elimination, the following logical reasoning must be carried out:

In the first round there are 16 players, so being matches between 2 players, there are 8 matches (16/2). In the second round, applying the same reasoning and taking into account that there are only 8 players left, since the others have been eliminated, there are 4 matches (8/2). The same in the semifinals, where there are 2 games (4/2), and finally, the final to a single game.

Therefore, since 8 + 4 + 2 + 1 equals 15, the number of matches played in the tournament is 15.

Step-by-step explanation:

Answer:

C = -5

Step-by-step explanation:

Functions

F(x) is defined as:

[tex]\displaystyleF(x)=\frac{C-x}{D-x}[/tex]

We know F(-2) is undefined. It comes from the fact that the denominator is 0 for this value of x, thus:

D - (-2) = 0

Solving:

D = -2

Substituting:

[tex]\displaystyleF(x)=\frac{C-x}{-2-x}[/tex]

We also know F(-1) = 4:

[tex]\displaystyle \frac{C-(-1)}{-2-(-1)}=4[/tex]

[tex]\displaystyle \frac{C+1}{-2+1}=4[/tex]

[tex]\displaystyle \frac{C+1}{-1}=4[/tex]

Multiplying by -1

C + 1 = -4

Solving for C:

C = -5

Answer:

D

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here r = 9, then

A = π × 9² = 81π cm² → D

Answer:

(d)

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° by 9 to find the value of one part of the ratio

180° ÷ 9 = 20° ← value of 1 part of ratio , then

4 parts = 4 × 20° = 80° ← largest angle

−18x^8−27x^7−21x^6−24x^5−15x^4−3x^3

Step-by-step explanation:

Answer:

$3

Step-by-step explanation:

Given :

Let game 1 = x ; game 2 = y

4x + 6y = 18 - - - (1)

5x + 5y = 20 - - - (2)

From (2)

x + y = 4

y = 4 - x

Substitute y = 4-x in (1)

4x + 6(4 - x) = 18

4x + 24 - 6x = 18

-2x = 18 - 24

-2x = - 6

x = 6/2

x = 3

Game 1 cost $3

Answer:

3/4 bucket

Step-by-step explanation:

Given that:

1/2 bucket of nut fills 2/3 of barrel ;

Letbthe number of bucket if nut which fills entire barrel = x

Fraction of entire barrel = 1 /1 = 1

1/2 bucket = 2/3 barrel

x buckets = 1 barrel

Cross multiply ;

(2/3)x = 1/2

2x / 3 = 1/2

2x * 2 = 3 * 1

4x = 3

x = 3/4

Hence, 3/4 bucket of nut will fill entire barrel

Step-by-step explanation:

By spinning once, the probability of landing on 2 is 1/8

The probability of landing on 5 is 1/8

The probability of landing on 2 or 5 is 1/8 + 1/8 = 2/8 = 1/4

So spinning 60 times, the number of times we expect a landing on 2 or 5 will be ;

1/4 * 60 = 15 times
