Answer:

1/2pi

Step-by-step explanation:

Since the formula for circumference is 2*pi*r and we know the R=1 so the of the whole circle is 2pi. This is a quarter of a circle so the answer is 1/2pi  

Answer:

1/2pi

Step-by-step explanation:

Answer:  x/ 8 < -2           and x< -16

Step-by-step explanation:

A numer x is divided by 8  is the same as   x/ 8   and x/8 has to be the less than  -2  so it will be    x/8 < -2  

x/8 < -2   TO solve the inequality, multiply 8 on both sides  to get

x < -16

The solution of expression is,

⇒ x < - 16

We have to given that,

An algebraic expression is,

''a number x divided by 8 is less than -2''

We can write as,

⇒ x / 8 < - 2

Solve for x,

⇒ x/8 < - 2

Multiply by 8;

⇒ x < - 2×8

⇒ x < - 16

Therefore, The solution of expression is,

⇒ x < - 16

Answer:

why technolgy is having a negitive impact on us:

1. affect our sleeping habbit.I say this because we get so addicted to them that when we need to sleep for our mental and physical health. we don't want to go to because there is so much stuff on the internet that we want to see and that causes us to mess up our sleeping habbits!  

2. pain: when we our on our lectronics we don't realize how we are sitting and so that causes neck pain and back pain and including bad posture!

positive impact:

1. a positive impact is that you can learn alot from the internet but not my point. My point is that there is alot  of learning opportunities ou there and that you don't have to stay in one spot to do something online you can travel while still doing what you have to!

Answer: Multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have 3(p/3) = 3(12)

p = 36 simplify

To check this work, you can substitute 36 for p:

36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

Answer:

The slope is 2/1

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First thing you should notice first is that the line is going up to the left, that means that the slope will be negetave. Then, follow the rise over run method. Start at any point on the line, im going to use (0,1). go up 2 and over 1. You get -2/1 aka -2. I hope this helps!

Answer:What About y = mx + b ? You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis.

Answer:

Each friend bought 3.45 bushels of corn.

Step-by-step explanation:

12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

Answer:

1.2*10^-2

Step-by-step explanation:

-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.

18/3=6, and 6 is an integer, so this is not the answer either.

1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.

49 is an integer, so this is not the answer:

Therefore, the answer to this problem is 1.2*10^-2

Hope this helped!

Answer:

[tex]1.2*(10-2)[/tex] cannot be written as an integer.

Explanation:

Fractions and decimals are not integers. All whole numbers and natural numbers are integers.

You can immediately identify that [tex]1.2*(10-2)[/tex]  cannot be written as an integer because the decimal is 1.2 and the only way it could become an integer is if it was multiplied by a number ending in 5 or with 5 as a factor (5,1 0, 15, 20, and so on). Also, it has a decimal point that isn't being multiplied by another decimal/fraction. In some cases, decimals or fractions multiplied by each other can equal an integer, but it's that's not the case in this instance.

However, if you couldn't identify this or you needed to check you answer, you could solve the expressions:

[tex]1.2*(10-2)\\1.2*(8)\\9.6[/tex]

9.6 is a decimal, therefore it is not an integer.

[tex]-3 + 0 = -3\\-3*0= 0[/tex]

I don't know if you were attempting to add or multiply, but in both cases, the sum and product equal an integer.

[tex]\frac{18}{3} = 6[/tex]

18 is divisible by 3, so you can assume that the quotient will be an integer. (3*6 = 18, to check your answer)

(To know if something is divisible by three, add the numbers of the dividend. If they equal a number that can be divided by three, you can assume that you'll get an integer and whole number.

For example: 1 + 8 = 9, 3*3 = 9)

[tex]\sqrt{49} =7[/tex]

The square root of 49 is 7. If you've memorized your square roots, you could identify quickly that the square root would be an integer. If you haven't it's okay, keep working on it!

I hope this helps!

Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.

Answer:

Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1
