20% = 0.20

6 * 0.20 = 1.2

6 + 1.2 = 7.2

Circle B has a radius of 7.2.

Circle Area = pi *r^2

Lets use 3.14 for pi

3.14 * 7.2^2 = Area of circle B

7.2 * 7.2 = 51.84

3.14 * 51.84 = 162.7776

Area of circle B is 162.7776

Rounded to 2 decimals, this is 162.78

A. 189.31

D. 162.78

E. 203.15

are all equal to or grater than 162.78

This table gives a few (x, y) pairs of a line in the coordinate plane.

katrin2010 [14]

Answer:

The x-intercept is : (22, 0)

Step-by-step explanation:

From the table values, we determine that it is a straight line as there is a constant change in x and y values.

i.e.

Any previous value of y can be obtained by subtracting 15 from the successor y value.

i.e.

60 - 15 = 45

45 - 15 = 30

so if continue, we can also determine some of the other values of y such as

30 - 15 = 15

15 - 15 = 0

Also, there is a constant change in x values. so, any previous value of x is obtained by subtracting 13 from the successor x value.

i.e.

74-13 = 61

61-13 = 48

48-13=35

35-13=22

So, from the above analysis, we determine that when the value of y = 0, the value of x = 22.

We also know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.

so, at y = 0, the value of x = 22.

Therefore, the x-intercept is : (22, 0)

A small airplane can hold 44 passengers.fifteen passengers board the plane a. Identify an inequality that represents the additio

iris [78.8K]

Answers:

Inequality is $15 + p \le 44$

Choice A) 30 more passengers cannot board the plane. Only 29 more passengers can board the plane

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

Explanation:

15 people are already on the plane.

p is a placeholder for a positive whole number representing the additional number of people that can get on the plane.

In total, the plane holds 15+p individuals.

This expression's largest possible value is 44. Think of it as the ceiling. In terms of math, we call it the maximum. Since at most 44 people can be on the plane, this means the inequality we'll set up is $15+p \le 44$

This says "15+p is less than or equal to 44". It's the same as saying "15+p is 44 or smaller".

---------------------------

To isolate p, we subtract 15 from both sides

Doing so leads to...

$15+p \le 44\\\\15+p-15 \le 44-15\\\\p \le 29$

We can see that the largest p can get is 29, meaning that at most 29 more people can board the plane. There's no way that 30 people can board. That unfortunate 30-29 = 1 person must wait for another plane.

This all shows why choice A is the answer.

----------------------------

As a way to check the answer, we can note how p = 29 leads to 15+p = 15+29 = 44. We've filled the plane to full capacity.

If p = 30, then 15+p = 15+30 = 45, and we've gone 1 seat overboard.

I need help with this queston

ozzi

Answer:

Step-by-step explanation:

The system of equations is

$3x+7y=31 \\3x-2y=-1$

The first step is to arrange like terms in colums, which is already done.

Then, we need to multiply a number by one equation in such way where we get opposite like terms. Notice that we need to multiply the first equation by -1

$-3x-7y=-31\\3x-2y=-1$

Then, we sum equations to obtain the value of one variable.

$0-9y=-32\\y=\frac{-32}{-9}\\ y=\frac{32}{9}$

Now, we use this value to find the second variable

$3x-2y=-1\\3x-2(\frac{32}{9} )=-1\\3x=-1+\frac{64}{9}\\ 3x=\frac{-9+64}{9}\\ 3x=\frac{55}{9}\\ x=\frac{55}{27}$

Therefore, the solution is (55/27, 32/9).
