Answer: 5%

Step-by-step explanation:

Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.

The percentage that Ryan uses on gas from his take-home pay will be:

= Amount used on gas / Take home pay × 100

= 125/2500 × 100

= 1/20 × 100

= 5%

He used 5% on gas.

Answer:

2,4,5 doesn't form a triangle

Answer:

y = -3x + 13

Step-by-step explanation:

y - 4 = -3(x - 3)

y - 4 = -3x + 9

y = -3x + 9 + 4

y = -3x + 13

For question 4 you would have 1560000. For question 5 you would have 660000

Step-by-step explanation:

Given:

The quadratic equation is:

[tex]6x^2-x-2=0[/tex]

To find:

The nature of the solutions by using the discriminant.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then its discriminant is:

[tex]D=b^2-4ac[/tex]

If D<0, then both roots are complex.

If D=0, then both roots are real and equal.

If D>0, then both roots are real and distinct.

We have,

[tex]6x^2-x-2=0[/tex]

Here, [tex]a=6,b=-1,c=-2[/tex]. So, the value of the discriminant is:

[tex]D=(-1)^2-4(6)(-2)[/tex]

[tex]D=1+48[/tex]

[tex]D=49[/tex]

Since [tex]D>0[/tex], then both roots are real and distinct.

Hence, the discriminant of the given quadratic equation is 49 and both roots are real and distinct.

Answer:

Step-by-step explanation:

Total surface area of a cylinder with height 5 is:

If we substitute r with x, we get:

Total surface area of two bases:

Correct choice is C

m1=3, m2= 1

point A= (-5,4)

point B=(7,-2)

x=m1x2+m2x1/ m1+m2 , y=m1y2+m2y1 / m1+m2

x= 3×7 +1×-5/3+1 , y= 3×-2+1×4 / 3+1

x= 21-5/4, y= -6+4/4

x= 16/4, y= -2/4

x= 4, y= 0.5

Answer:

2 and [tex]\frac{8}{5}[/tex]

Step-by-step explanation:

when you divide by a fraction you just multiply by its reciprocal

[tex]\frac{2}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex] = [tex]\frac{2}{3} * \frac{3}{1}[/tex]

then just solve

[tex]\frac{6}{3}=2[/tex]

for the second one do the same thing

[tex]\frac{4}{5} * \frac{2}{1} =\frac{8}{5}[/tex]

Step-by-step explanation:

A. y-5=-4x+4

y=-4x+4+5

y= -4x +9

(0,9)(9/4,0)

Answer:

0 is the only number without a reciprocal

Answer:

[tex]24 = x[/tex]

Step-by-step explanation:

Write a proportion. Remeber that same units corresponds with each other.

[tex] \frac{8}{3} = \frac{x}{9} [/tex]

Cross multiply

[tex]72 = 3x[/tex]

[tex]24 = x[/tex]

Answer: Volume of prism is LxWxH which is 360

Step-by-step explanation:

Answer:

-3 and -2

Step-by-step explanation:

7x² + 19x + 21 = 4x² + 4x + 3

combine like terms:

3x² + 15x + 18 = 0

3(x² + 5x + 6) = 0

(x + 3)(x + 2) = 0

x = -3

x = -2

Answer:

The answer is "[tex]153.86 \ in^2[/tex]"

Step-by-step explanation:

The circular light which fits around rather than is sufficiently large for fire a camera is indeed a ring light. The ring light provides light with very little darkness, as the bright light is very close to a lens's vertical system. It's also usually called glamour or brightness of beauty.

Let's Each light surface area has [tex]38.465\ in^2[/tex].

Therefore, the total area of four lights is [tex]38.465 \times 4= 153.86\ in^2[/tex].

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

Answer:

the property of being perpendicular is the relationship between two lines which meet at a right angle.

parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
