3 equivalent ratios 7.7: 4.1

Answer:

  b.  ellipse

Step-by-step explanation:

The squared terms have the same sign and different coefficients. That means the equation describes an ellipse.

__

Additional comment

both variables are highest degree 2:

  coefficients have the same sign and magnitude: circle

  coefficients have the same sign and different magnitude: ellipse

  coefficients have different signs: hyperbola*

only one variable has highest degree 2:

  parabola

____

* If the equation can be factored to a product of linear terms that is zero, then the equation is of two intersecting lines. This is a degenerate case of the hyperbola in which the major axis is zero: the two vertices are the same point.

Answer:

x=4

Step-by-step explanation:

In a parallelogram opposite sides are congruent. That means BC and AD are congruent if ABCD must be a parallelogram.

[tex]6+3x=x+14\\6+2x=14\\2x=8\\x=4[/tex]

To double check you can substitute x into the equations again and check if they are equal.

[tex]6+3(4)=(4)+14\\6+12=18\\18=18[/tex]

Answer:

A: Vertical angles are congruent, C is the midpoint of BE, and ∠B ≅ ∠E.

B: C is the midpoint of AD, BC ≅ EC, and Vertical angles are congruent.

C: I assume you cannot use CPCTC so AAS and ASA.

Step-by-step explanation:

A: Since vertical angles are congruent, the interior angles using point C of the triangles are congruent. If C is the midpoint of BE, BC ≅ EC. Draw the congruent parts based on the 3 statements with tick marks and you will see that you have two pairs of congruent angles with an included pair of congruent sides, so ASA applies.

B: If C is the midpoint of AD, AC ≅ DC. Since vertical angles are congruent, the interior angles using point C of the triangles are congruent. Draw the congruent parts based on the 3 statements with tick marks and you will see that you have two pairs of congruent sides with an included pair of congruent angles, so SAS applies.

C: ∠B ≅∠E and ∠A ≅∠D since these are pairs of alternate interior angles. Since vertical angles are congruent, the interior angles using point C of the triangles are congruent and it is given that AB ≅ DE. When making the appropriate marks, you will see that only AAS and ASA can be used without CPCTC.

Simplified: xy/3y+4x

factored: 1/(3/x)+(4/y)

Step-by-step explanation:

Half of 40 is 20 and luckily they already gave us how much she would earn if she worked 20 hours.

So all we have to do is multiply the amount of money she earned when she worked 20 hours by 2 to see how much she earned when she worked 40 hours.

20 hours:165 dollars or 20:165

20 x 2= 40 and 165x2=330

So if Monique worked 40 hours she would earn $330.

Answer:

C. 51

Step-by-step explanation:

I did this already on a test and got the answer right.

Answer:

C

Step-by-step explanation:

let's sort the numbers first :

35, 38, 43, 45, 51, 51, 55, 62, 64

the median is now the middle number of the sorted list :

51

Alternate exterior angles are formed by a transversal intersecting two parallel lines, therefore, your alternate exterior angles are <1 and <5.

Your alternate interior angles are  <2 and <6/ <3 and <7.

Corresponding angles are formed when two parallel lines are intersected by a transversal. (<1 and <3)

Vertical angles are formed when two lines intersect each other. Therefore, <1 and <7 fall into this category.

Answer:

504 [tex]in^{2}[/tex]

Step-by-step explanation:

area of the square -> 14*14 = 196

area of one of the triangles -> 1/2(11*14) = 77

area of all four triangles -> 77 * 4 = 308

surface area = area of square + area of four triangles

= 196 + 308

= 504

Answer:

y = -5/2x + 27/2

Step-by-step explanation:

line formula is y = mx + b

perpendicular means number next to the x (slope or m) becomes a negative reciprocal

2/5x -> -5/2x

then use point slope formula

y - y1 = m (x - x1)

y - 6 = -5/2 (x - 3)

y - 6 = -5/2x + 15/2

y = -5/2x + 15/2 + 6

y = -5/2x + 15/2 + 12/2

y = -5/2x + 27/2

Using the volume of the rectangular prism, it is found that it takes 7 hours to fill the pool.

The volume of a rectangular prism of dimensions l, w and h is given by the multiplication of it's dimensions, that is:

V = lwh.

In this problem, the dimensions in meters are: l = 7, w = 3, h = 0.75. Hence, the volume in cubic meters is:

V = lwh = 7(3)(0.75) = 15.75.

It fill 2.25 cubic meters per hour, hence, for 15.75 cubic meters, the time taken is:

15.75/2.25 = 7 hours.

Answer:

D. 30%

Step-by-step explanation:

Answer:

D) 30%

Step-by-step explanation:

→ a = 0.3

General formula,

→ a × 100 = %

Let's solve the problem,

→ 0.3 × 100

→ 30%

Thus, option (D) is answer.

Answer:

decrease of 38% (to nearest percent)

Step-by-step explanation:

Percent change = [ (difference between final and initial value) ÷ initial value] x 100

⇒ percent change = [(2100 - 1300) ÷ 2100] × 100 = 38% (to nearest percent)

Answer:

A

Step-by-step explanation:

The initial amount is 64, so that would be the y-intercept.

Each piece of wood, x, is [tex]6\frac{1}{4}[/tex] inches long, so x pieces would be [tex]6\frac{1}{4}x[/tex] pieces long.

Because you're subtracting the length of the pieces from the total length, you would subtract [tex]6\frac{1}{4}x[/tex] from 64.

Answer:

a = 3

b = -7

c = 13

Step-by-step explanation:

[tex]\sf{given \ equation: 3x^2+bx+c[/tex]

[tex]\sf{sum \ of \ roots :\sf\frac{7}{3}[/tex]

[tex]\sf{product \ of \ the \ roots:\frac{13}{3}[/tex]

[tex]\sf{sum \ of \ roots \ = -\dfrac{coefficient \of \ x}{coefficient \ of \ x^2} }[/tex]

[tex]\sf \frac{-b}{3} = \frac{7}{3}[/tex]

[tex]\sf b = \frac{-7*3}{3}[/tex]

[tex]\sf b =- 7[/tex]

[tex]\sf{product \ of \ roots \ = \dfrac{constant \ term}{coefficient \ of \ x^2} }[/tex]

[tex]\sf{\frac{c}{3} =\frac{13}{3}[/tex]

[tex]\sf c = \frac{13*3}{3}[/tex]

[tex]\sf c = 13[/tex]

Therefore found that a = 3, b = -7, c = 13

Answer:

b = -7

c = 13

Step-by-step explanation:

[tex]3x^2+bx+c[/tex]

[tex]\textsf{sum of roots}=\dfrac{-b}{a}\\\\\textsf{product of roots}=\dfrac{c}{a}[/tex]

[tex]\textsf{Given sum of roots}=\dfrac73:[/tex]

[tex]\implies \dfrac{-b}{a}=\dfrac73[/tex]

[tex]\implies a=3, b=-7[/tex]

[tex]\textsf{Given product of roots}=\dfrac{13}{3}:[/tex]

[tex]\implies \dfrac{c}{a}=\dfrac{13}{3}[/tex]

[tex]\implies a=3, c=13[/tex]

Therefore,

[tex]3x^2-7x+13[/tex]

NB: The actual calculated roots are imaginary numbers as the function [tex]f(x)=3x^2-7x+13[/tex] does not intercept the x-axis
