What is the answer to this question

Answer:

domain is x = 3

Thus domain means that for every fruit cup costs $3

Range is f(20) = 60

Step-by-step explanation:

We are given;

Total students for the fruit cup party = 18

Total teachers for the fruit cup party = 2

Cost of each fruit cup =$ 3

Delivery charge = $ 10

Now, the total number of people attending the party = Total number of students + Total number of teachers

Thus;

Total number of people attending party = 18 + 2 = 20

Since cost of each fruit cup is $3.

Thus, for 20 fruit cups, the function is;

f(x) = 20x where x is cost of each fruit cup.

It means the cost of 20 fruit cups = $3 × 20 = $60

Thus, domain is x = 3

Thus domain means that for every fruit cup costs $3

Range is f(20) = 60

We need to know about inequality to solve this problem. The solution of the inequality is x>-4/3.

Inequality represents the comparison between two unequal expressions. Two expressions can be related to each other as greater than, less than,greater than or equal to or less than or equal to. While solving inequality we always have to keep in mind the change of sign and corresponding change of the comparison. Here in the question we have an inequality of the variable x, we have to get a solution for x by solving this inequality.

6x+4>-3x-8

6x+3x>-8-4

9x>-12

x>-4/3

Therefore the solution set that we get from the inequality 6x+4>-3x-8 is x>-4/3.

Answer: 7 feet

Step-by-step explanation:

1 foot = 12 inches

7 * 12 = 84

7 feet = 84 inches

84 inches are more than 81 inches

Answer:

7 feet is greater

Step-by-step explanation:

you can change feet to inches. one foot is the same as 12 inches. so 7 feet = 84 inches. so 84 > 81 so 7 feet is greater

Answer:

8 minutes

Step-by-step explanation:

If it takes 12 birds to eat 12 packets of food in 6 minutes that means it takes .5 minutes for 1 bird to eat 1 packet of food. 6÷12=.5

If there is 9 birds to eat 36 packets you first have to multiply the amount of birds times the rate it takes one to eat one packet. 9×.5=4.5 and with this now you know how many packets of food the group of 9 birds can eat per minute. Finally you divide the amount of packets by the amount of packets of food the group of 9 birds can eat per minute. 36÷4.5=8 And that's how they take 8 minutes to eat the 36 packets of food.

Solving using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

We have a=1, b=8 and c=58

Putting values and finding value of x

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-8\pm\sqrt{(8)^2-4(1)(58)}}{2(1)}\\x=\frac{-8\pm\sqrt{64-232}}{2}\\x=\frac{-8\pm\sqrt{-168}}{2}\\We\:know\sqrt{-1}=i \\x=\frac{-8\pm2\sqrt{42}\:i}{2}\\x=\frac{2(-4\pm\sqrt{42}\:i)}{2}\\x=\frac{2(-4+\sqrt{42}\:i)}{2}, x=\frac{2(-4-\sqrt{42}\:i)}{2}\\x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i[/tex]

So, we get value of x: [tex]\mathbf{x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i}[/tex]

Option C is correct.

Step-by-step explanation:

The perimeter of this figure, to the nearest unit, is 37.9 units and the area of this figure, to the nearest square unit is 153.54 square units.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.

We have a figure shown in the picture made with squares and circles.

To find the perimeter of the figure.

First, calculate the circumference of the circle portion.

The circumference of the 1/4 circle = (1/4)2πr

The radius of the circle r = 5 units

The circumference of the 1/4 circle = (1/4)2π(5)

The circumference of the 1/4 circle = 7.85 units

The perimeter of the figure = 10 + 5 +7.85 + 5 + 10

The perimeter of the figure = 37.85 units ≈ 37.9 units

The area of the figure = area of the square - an area of the square(5×5) +

area of the 1/4 circle

The area of the figure = 10×10 - 5×5 + π(5)²

The area of the figure = 100 - 25 + 78.53

The area of the figure = 153.54 square units

Thus, the perimeter of this figure, to the nearest unit is 37.9 units and  the area of this figure, to the nearest square unit is 153.54 square units.

Correct answer is B. the probability that the total of the two dice will add up to 7 or 11 is 8/36

Suppose two dice are tossed

That means n(s)= 6×6 =36

Let E=Addition of number is 7 or 11

Probability of getting 7 is

N(E)= {(4,3),(3,4),(5,2),(2,5)(6,1)(1,6)}

Probability of get 11 is

{(6,5)(5,6)}

Total probability is 8

E=8

S=36

P(E)=n(E)/n(S)

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.

x+(2x+15)+the measure of angle Q should equal 180.

Since everything is addition, the parenthesis can be removed.

x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Answer:

y = -x + 8

Step-by-step explanation:

The equation can be written as;

y = mx + b

where b is the y-intercept

From the diagram , b= 8

y = mx + 8

To get m, substitute (8,0 ) into the equation

0 = 8x + 8

x = -8/8

x = -1

So the full equation is;

y = -x + 8
