The city of Atlanta is growing at a rate of 2.04% each year. The 2019 population of Atlanta is 486,290 people.

What would be the Each year would it be 1 or 365?

Answers

Answer:

1

Step-by-step explanation:

The "each year" would be represented as a 1. Using the number 365 would represent the days in a year but not the entire year as a whole. For example, if we were to apply the 2.04% population increase to the population of 486,290 then that would give us the new population for the year 2020 which is 1 year more than 2019.

Equation of parabola: y=6x+8.

What is the parabola?

In mathematics, a parabola is a planar curve that is mirror-symmetrical and generally U-shaped. It matches a variety of seemingly dissimilar mathematical formulations, all of which identify the same curves.

A point and a line are two ways to describe a parabola a plane curve produced by a point moving so that its distance from a fixed point equals its distance from a fixed line:

Apollonius, who discovered numerous features of conic sections, is credited with the name "parabola." It signifies "application," referring to the "application of regions" notion, which, as Apollonius demonstrated, has a connection with this curve.

A banana's curving shape is quite similar to a parabola. As a result, it is one of the best instances of parabolic objects in common use.

Cheryl paid $37.20 for 12 gallons of ice cream for a school picnic. how much would 1 quart of ice cream cost? group of answer choices $4.10 $0.68 $0.78 $3.10

Answers

Cheryl, that paid $37.20 for 12 gallons of ice cream for a school picnic would pay $0.78 for 1 quart of ice cream

To solve this problem, we have to state the equation using the information of the problem

Information about the problem:

Payment= $37.20Amount= 12 gallons1 quart cost=?

Converting the amount unit from gallon to quart, we get:

12 gallons * (4 quart / 1 gallon) = 48 quarts

12 gallons are equivalent to 48 quarts

Calculating how much would cost 1 quart of ice cream:

1 quart cost = payment / amount(quart)

1 quart cost = $37.20 / 48 quarts

1 quart cost = $0.78

Ezra has two weeks to sell popcorn to earn money for camp. For each unit of popcorn that he sells, Ezra will earn $5. He wants to earn at least $250
. During the first week he earned $105.
How many units of popcorn must Ezra sell in the second week to earn at least $250 in the two weeks combined?

Answers

okay so-
in the first week he sold 21 units of popcorn
he needs to sell 50 units in all
so 50-21= 29
he needs to sell 29 more units of popcorn

The number of units that needs to be sold to earn at least $250 is 20.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The minimum amount that needs to be earned = $250

One unit cost = $5

The amount earned in the first week = $105

Number of units = x

The number of units to sell in the second week.

150 + 5x ≥ 250

5x ≥ 250 -150

5x ≥ 100

x ≥ 20

Thus,

20 units need to be sold to earn at least $250.

Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2

1

slope intercept form that represents the new line.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y=x-2

We know that Reflecting over the x-axis inverts the sign of the y-coordinate.

Thus, after reflecting over the x-axis, the equation would be:

-y = x - 2

Now, writing the equation in the slope-intercept form

y=mx+b

where

m is the slope and b is the y-intercept

so the equation in the slope-intercept form

-y = x - 2

y = -x + 2

Here,

The slope = m = -1The y-intercept = b = 2

n points are chosen at random on the cicumference of a circle. a convex n-gon (n sided polygon) is drawn by joining these n points. what is the probability that the center of circle lies inside the region of n-gon?

Answers

The probability that the center of the circle lies inside the region of n-gon = 1/2

Let the N point be chosen randomly on the circumference of the circle.

Let's take N as  a1, a2, a3,…….an.

Now we need to find the probability that how many centers lie inside the region of n-gon. As there will be n- sided polygons can be formed inside the circle by joining all the points.

So here are the Possible Outcome is 2. One center may lie outside the polygon and the other which lie inside the center.

But we want one which lies inside the center. So our Favorable Outcome is 1.

So the Probability = Favorable outcome \ possible outcome

                                = 1/2

the length of one side of a rectangle is p cm and width is 3(p-2) cm the perimeter is 44 cm find the length and width of rectangle​

Answers

Answer:

Length = 7cm, Width = 15cm

Step-by-step explanation:

Length = p

Width = 3(p-2)

          = 3p-6

Perimeter = length + width + length + width

                = p + 3p-6 + p + 3p-6

                = 8p-12

8p - 12 = 44

Isolate 8p.

8p = 44+12

    = 56

Find p.

p = 56 ÷ 8

p = 7

Length = 7cm

Width = 3(7)-6

          = 21-6

          = 15cm
