There are 8 billion people on earth. if you counted one number every second, how many days would it take to count to 8 billion?

Answer:

1 inch per 2 hours (it may be 0.5/hour)

Step-by-step explanation:

The graph shows there is 1 inch of snow after 2 hours of snowfall, and 2 inches after 4 hours, so the unit rate is 1 inch per 2 hours or 0.5/hour

Answer:

your answer is 9,42

Step-by-step explanation:

This is because if you follow the pattern:

5,38

6,39

7,40

8,41

9,42

so (9,42) is your answer

Answer:

Answer 10

Step-by-step explanation:

Answer:

Simplifying the expression, the answer would be [tex]81u^1^2v^8[/tex].

Process:

Basically, you just need to multiply the power on the outside with the powers on the inside of the parenthesis. Then, for the base take -3 to the fourth power which will lead you to your final answer [tex]81u^1^2v^8[/tex].

Answer:

Team 1 -- 7

Team 2 -- 6

Step-by-step explanation:

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Answer:

3x-x+2=4

Step-by-step explanation:

You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.

Answer:

y = 3/4x + 5

-3x + 4y = 20

Step-by-step explanation:

In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)

First change that standard form equation to slope-intercept form:

1. 4x + 3y = 8

2. 3y = -4x + 8

3. y = -4/3x + 8/3

Step 1 is given.

In step 2, 4x was subtracted from both sides.

In step 3, both sides were divided by 3.

Slope-intercept form:

y = mx + b

m is the slope and b is the y-intercept.

m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)

b = 5; the y-intercept was stated in the problem

Now, you put it together: y = 3/4x + 5

Standard form:

You can just change the slope intercept form back into standard form by moving the numbers around a bit:

1. y = 3/4x + 5

2. -3/4x + y = 5

3. -3x + 4y = 20

Step 1 is given.

In step 2, 3/4x was subtracted from both sides of the equation.

In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

Answer:

Circle: 18.85

Square: 9.6

The circle has a greater perimeter.

Step-by-step explanation:

The formula to calculating the circle is C=2π r

To calculate the square, just multiply 9.6x4, since a square has 4 sides.

Answer:

C:) 21.47 cm²

Step-by-step explanation:

A=wl=2.1 x 10.7=22.47

Answer: the answer would be B.

Step-by-step explanation:

7 1/4 + x = 18

x = 3/4

3/4 + 17 1/4 = 18

hope this helps. :)

Answer:

1. A=18

2. A= 48

Step-by-step explanation:

1. Area = 1/2 x base x height

The base is 9 and the height is 4

1/2 x 9 x 4= 18

2. Area = L x W

The length is 12 the width is 4

12 x 4 = 48

Answer:

-a - 8

Step-by-step explanation:

Answer: Answer: a-2. Step-by-step explanation: 3a+3-2a-5. like terms must be together hence. 3a-2a=a. 3-5=-2. ans ;a-2.

Step-by-step explanation:

Answer: y = 16x   or  C = 16×f  

The number of cookies is 16 for each cup of flour used

Step-by-step explanation:

You can take numbers from the graph. For example, Number of Cookies: 192 and the Cups of flour: 12.  Divide the number of cookies by the amount of flour

192÷12 = 16

Check other numbers to be sure  96÷6 = 16

288÷18 = 16

You could fill in the chart by multiplying Cups of Flour by 16 to find the number of Cookies

C = 16 × f

C = 16 × 3

C = 48

Answer:

40 miles

Step-by-step explanation:

First, change the 15 minutes to 0.25 hours and 3 minutes to 0.05 because we are working with mph.

let x be the normal driving time to work in hours so 40x is the driving to work

since we know distance = speed multiplied by time we do

50(x-0.25+0.05)=40x

50(x-0.2)=40x

50x-10=40x

50x-40x=10

10x=10

x=1 hour normal time to work

therefore

40(1) = 40 mi to work

Confirm this by finding the dist when he went 50 mph for 48 min (0.8hrs)

50(1-.25+0.05) = 50(.8) = 40 mi also

Place a point on the 2 on the y-axis. Place another point on 1.3 on the x-axis. Then draw a straight line through the points from top left to bottom right.
