Answer:

$171

Step-by-step explanation:

Price of lemonade = $9 per cup

Quantity sold = 19 cups of lemonade

Revenue = price of the product × quantity of the product sold

Silvia's total revenue = price × Quantity

= $9 × 19 cups

= $171

Silvia has made a total of $171 from selling 19 cups of lemonade at $9 each

-7<x<-3

Step-by-step explanation:

separate into two inequalities:

3x+15>-6

3x+15<6

solve inequalities:

3x>-21........3x<-9

x>-7.............x<-3

-7<x<-3

Answer:

x=203/18

Step-by-step explanation:

convert the decimal into a fraction

203/50/x = 9/50 / 1/2

simply the complex fraction:

203/50x = 9/25

cross multiply

450x = 5075

divide both sides by 450:

x= 203/18

Answer:

X=11.2778

Step-by-step explanation:

4.06/X=0.18/0.5

cross multiply

0.18×X=4.06×0.5

0.18X=2.03

divide both sides by 0.18

0.18X/0.18=2.03/0.18

it becomes

X=2.03/0.18

X is therefore 11.2778

Answer:

∠ D = 48°

Step-by-step explanation:

Since AC ~ BC then Δ ABC is isosceles and the base angles are equal, thus

∠ B = ∠ C = 69°, then

∠ ACB = 180° - (69 + 69)° = 180° - 138° = 42° ( sum of angles in Δ )

∠ DCE = ∠ ACB = 42° ( vertical angles )

∠ D = 180° - (90 + 42)° = 180° - 132° = 48°

Answer:

Step-by-step explanation:

Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side

Length of a side of the given regular hexagon = 3x + 5

Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30

Length of a side of the given regular pentagon = 4x - 1

Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5

Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:

18x + 30 = 20x - 5

Solve for x.

Subtract 20x from both sides

18x + 30 - 20x = 20x - 5 - 20x

-2x + 30 = -5

Subtract 30 from both sides

-2x+ 30 - 30 = -5 - 30

-2x = -35

Divide both sides by -2

x = -35/-2

x = 17.5

Length of a side of pentagon = 4x - 1

Plug in the value of x

4(17.5) - 1 = 70 - 1 = 69

length of a side of the pentagon = 69

Step-by-step explanation:

Input Equation can be rewritten:

= (9*1/2)+(7*-91/12)

= (9/2)+(7*-91/12)

= (4.5)+(7*-91/12)

= 4.5+(7*-91/12)

= 4.5+(-637/12)

= 4.5+(-53.083333333333)

= 4.5+-53.083333333333

= 4.5-53.083333333333

= -48.583333333333

Answer:

A) on edge2020

Step-by-step explanation:

The greatest amount of time when they worked together is 2.4 hours.

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

Given:

Randy at most 4 hours to clean the offices.

Trey at most 6 hours to clean the offices.

If they work together, they will clean

1/4 + 1/6 = 5/12 of the offices.

Let x be the greatest amount of time it would take them to clean the offices together.

Thus,

5*x/12=1

5x=12

x= 12/5

x= 2.4 hours.

Answer:

(x - 8)(x + 4)

Step-by-step explanation:

We need to find something that multiplies to 32 and adds up to 4.

The 2 special numbers would be -8 and 4.

-8(4) = -32

-8 + 4 = -4

We then simply write out the factored form:

(x - 8)(x + 4)

Answer:  (x+4)(x-8)    

Step-by-step explanation:

x^2 - 4x -32         Find two numbers that their product is -32 and their sum is -4. The numbers -8  and 4 will work out because -8 times 4 is -32 and -8 plus 4 is -4.

Now rewrite the whole polynomial as

x^2 +4x -8x -32     Now group them  

(x^2 +4x)  (-8x -32)    Now factor each side

x(x +4)   -8(x +4)         factor out x+4

(x+4)(x-8)

Step-by-step explanation:

The improper fraction is 37/6.

What is improper fraction?

An improper fraction is defined as a fraction whose numerator is greater than the denominator. Suppose, x/y is an improper fraction, such that x > y. It is therefore, the improper fraction is always greater than one.

Fractions have two parts, numerator and denominator. If  ⅓ is a fraction, then 1 is the numerator, and 3 is the denominator. An improper fraction has a numerator greater than the denominator. For example, 3/2 is an improper fraction.

Given fraction is [tex]6\frac{1}{6}[/tex]

firstly we will multiply 6 by 6 and then we will add 1

Answer: Slope = -7/5

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

Explanation:

Pick any two rows you want. I'll select the first two rows.

Each row represents an (x,y) point

The first row means (-8,55) is one point and the second row means (2,41) is another point.

Use these two points in the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (41-55)/(2- (-8) )

m = (41-55)/(2 + 8)

m = -14/10

m = -7/5 is the slope

The negative slope means the line goes downhill as you move from left to right.

Specifically, every time it drops 7 units the line moves over to the right 5 units.

slope = rise/run = -7/5

rise = -7, negative rise means we go down 7 spaces

run = 5 means we move to the right 5 spaces

Answer:

12.5%

Step-by-step explanation:

Step 1:

We need to find out the percentage of picking a marble that is red. In total, there are 10 marbles, and there are 5 red. To find the probability of picking a red marble, you need to do:

# of red / total marbles.

There are 5 red marbles and 10 total marbles, so the probability of getting a red marble is 5/10, and you can simplify it to 1/2 (5/10 * 5/5).

Step 2:

Now we can start finding the probability of finding the probability of choosing three red marbles in a row. Since we need to find the probability of choosing red marbles three times, you can multiply 1/2 by itself 3 times (1/2 * 1/2 * 1/2).

1/2 * 1/2 * 1/2 = 1/8

Step 3:

Now we need to convert the fraction into a percentage. You can find the percentage by dividing 1 by 8. You should get 0.125, and you can multiply 0.125 by 100, and your final answer should be 12.5%.
