Answer:

-1/2x

Step-by-step explanation:

-1/2x represents the slope because it shows that the line is going down 1/2 every x. 1/4 would be where the line started or the y-intercept.

If the sum of three consecutive numbers is 36. Find the numbers.

aleksandrvk [35]

Answer:

11, 12, 13

Step-by-step explanation:

x is the first number

(x + 1) is the second number

(x + 2) is the third number

x + x+1 + x+2 = 36

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 11 ← the first number

the second number = x + 1 = 11 + 1 = 12

the third number = x + 2 = 11 + 2 = 13

Answer:

Slope of line is $\pi$

Step-by-step explanation:

Given that the company logo has four concentric circles.

To plot the line on the graph take point as ( Diameter, Circumference )

Circumference of a circle is given by C= $\pi D$

Where D is the diameter.

To draw a line, we need at least two-point.

Now,

Take D=1

Circumference of a circle will be C= $\pi D=\pi$

Required point is (1, $\pi$ )

Take D=0

Circumference of a circle will be C= $\pi D=0 \pi$

Required point is (0,0)

The slope of line is given by s= $\frac{Y2-Y1}{X2-X1}$

Hence,

s= $\frac{Y2-Y1}{X2-X1}$

s= $\frac{0-[tex]\pi$ }{0-1}[/tex]

s= $\frac{[tex]\pi$ }{1}[/tex]

s= $\pi$

Thus, Slope of line is $\pi$

Hi! I would like help on this, I’m a first-timer on brainly! The answer choices are:

sergeinik [125]

Answer:

Step-by-step explanation:

No matter what value you multiply a, the fraction will remain unchanged. That is because you can divide an a out from the numerator and the denominator. Thus, doubling a has no affect on the fraction, and in fact, u can simplify it to just bc. Now, if you halve b, it will simply just halve the actual value. When you halve b, you are simply executing (1/2)(b)(c). Therefore, you can rearrange the expression to be (1/2)(bc), which is just halving bc. If you decrease by 1/2, it's the same thing as being half of the value it was before. Therefore, the answer is b.

The density of oxygen is 0.001429 grams per cubic centimeter. How is this number written in

Anika [276]

We have been given that the density of oxygen is 0.001429 grams per cubic centimeter. We are asked to write the given number in scientific notation.

To convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.

When a decimal is to the left of given number, then we need to move the decimal to right such that the number gets between 1 and 10. Then, we multiply the number by negative power of 10 that many times, we moved the decimal to right.

We can see that decimal is to left of our number. To place decimal after 1, we have to multiply 10 to 3 times. To keep the value of number same we will multiply the same negative power (negative 3).

$0.001429\times 10^3\times 10^{-3}$

$(0.001429\times 10^3)\times 10^{-3}$

$(1.429)\times 10^{-3}$

$1.429\times 10^{-3}$

Therefore, the number 0.001429 will be $1.429\times 10^{-3}$ in scientific notation.
