Answer:

Step-by-step explanation:

y=mx+b

m is the slope and b is the y intercept

The y intercept would be whatever the number is when the x is at 0

So the answer is 5

Parallel means the same. And perpendicular means opposite. If you need the find the slope of the question, you need to put your equation in y=mx+b. So 4=5x+x. Therefore 5x is the slope since it replaced m in the equation. You need to rearrange your equation into slope form intercept

which of the following correctly explains why the formula for the circumference of a circle is 2 pi r. Pi is defined as the rati

Kobotan [32]

Let
C---------> the circumference of a circle
D---------> diameter of a circle
r----------> radius of a circle

we know that
C=2*pi*r
D=2*r
so
C=D*pi-------------> pi=C/D
Pi is defined as the ratio of the circumference of a circle to the diameter of that Circle
when you multiply the diameter in both numerator and denominator
pi*D=(C/D)*D------> pi*D=C
and the diameter is two times the radius
so
D=2*r
C=pi*D------> C=pi*(2*r)-----> C=2*pi*r

therefore

the answer is the option D
Two times r equals the diameter of the circle. Pi equals the circumference divided by the diameter. When you multiply, the diameter is in both the numerator and the denominator, which cancels out, leaving the circumference

You are making 6 quarts of

Ivenika [448]

1.5 quarts of 20% fruit juice and 4.5 quarts of 100% fruit juice.

Step-by-step explanation:

Let x be the number of quarts of 100% fruit juice

Let y be the number of quarts of 20% fruit juice

The equation for amount of quarts is ;

x+y=6

x=6-y-------------------equation 1

The equation for the amount of quarts of fruit juice to get 80% fruit juice will be;

x(100%)+y(20%)=80%------however you need to make 6 quarts so divide first portion of equation by 6

{x(100%)+y(20%) }/6=80%

Multiply both parts of the equations by 6

x(100%)+y(20%)=480% --------------equation 2

Use equation 1 in 2

(6-y)(100%)+y(20%)=480%

600-100y+20y=480

600-80y=480

600-480=80y

120=80y

120/80 =y

1.5=y

Use the value of y in equation 1

x=6-y , x= 6-1.5=4.5

So you have,

1.5 quarts of 20% fruit juice and 4.5 quarts of 100% fruit juice.

PLEASE HELP ILL MARK BRAILIEST!!! P.S please show how you figured it out

Arturiano [62]

Answer:

I think that the answer is either B or C

Step-by-step explanation:

I concluded to this answer simply by looking at where the lines were placed.

Remember that if a line is not touching, but next to another line, they are parallel to each other? Well, that doesn't change here. since, {m angle 1} and {m angle 2} added together equal 180, I would believe that the answer is C, but I may be wrong.

Well, I hope that helps :)

How many roots does the equation 3x² = 1 - 7x have and what is the nature of the roots

AnnyKZ [126]

Answer:

Step-by-step explanation:

Rewrite this quadratic in standard form: 3x^2 + 7x - 1.

The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or

7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots

If the circle has the same diameter as the edge length of the square, then the area of this circle is ___________the area of the

WINSTONCH [101]

Answer:

The area of this circle is $(\frac{\pi}{2} )$ the area of the square.

For the uniform electric field normal to the surface, the flux through the surface is electric field multiplied by the area of this surface.

Therefore, Φsquare is $(\frac{2}{\pi} )$ ϕcircle

Step-by-step explanation:

Area of the circle is given by;

$A_c = \frac{\pi d^2}{4}$

Area of the square is given by;

$A_s = L^2$

relationship between the edge length of the square, d, and length of its side, L,

$d = \sqrt{L^2 + L^2} \\\\d = \sqrt{2L^2}$

But area of the square , $A_s = L^2$

$d = \sqrt{2A_s}$

Then, the area of the square in terms of the edge length is given by;

$A_s = \frac{d^2}{2}$

Area of the circle in terms of area of the square is given by;

$A_c = \frac{\pi d^2}{4} = \frac{\pi}{2}(\frac{d^2}{2} )\\\\But \ A_s = \frac{d^2}{2} \\\\A_c = \frac{\pi}{2}(\frac{d^2}{2} )\\\\A_c = \frac{\pi}{2}(A_s )$

For the uniform electric field normal to the surface, the flux through the surface is electric field multiplied by the area of this surface.

Ф = E.A

Flux through the surface of the circle is given by;

$\phi _{circle} = E.(\frac{\pi d^2}{4})$

Flux through the surface of the square is given by;

$\phi _{square} = E.(\frac{d^2}{2} )\\\\\phi _{square} =E.(\frac{d^2}{2} ).(\frac{\pi}{2} ).(\frac{2}{\pi} )\\\\\phi _{square} =E.(\frac{\pi d^2}{4} ).(\frac{2}{\pi} )\\\\\phi _{square} =(\phi _{circle}).(\frac{2}{\pi} )$

Therefore, Φsquare is $(\frac{2}{\pi} )$ ϕcircle
