The answer is C; x^4y^12z^16

Answer:

ok well i got it in multipul ways

Step-by-step explanation:

in fraction form its 61/10

in decimal for its 6.1

in mixed number form its 6  1/10

The answer is 6.1 as a decimal. 61/10 or 610 as a percentage.

Answer:

y = - 1.25x + 9

Step-by-step explanation:

A(0,9)  B(4,9)   C(4,4)

AB² = (4-0)² + (9-9)² = 16

AC² = (4-0)² + (4-9)² = 41

BC² = (4-4)² + (4-9)² = 25

AC is hypotenuse with y interception of 9

slope = 5/4 = -1.25

equation: y = - 1.25x + 9

Answer:

15

Step-by-step explanation:

y= 15 because 5 x 15 is 75 and 51+54+75= 180

Answer:

y=15

Step-by-step explanation:

51+54=105

180-105=75

75÷5=15

y=15

OR

5y+51+54=180⁰

5y+51=126

5y=75

y=75÷5

y=15

Answer/Step-by-step explanation:

✔️m<1 + 52° = 180° (consecutive angles angle)

m<1 = 180 - 52

m<1 = 128°

✔️m<2 = 52° (alternate interior angles are congruent)

✔️m<3 = 47° (alternate interior angles are always equal)

✔️m<4 + 47° = 180° (consecutive angles)

m<7 = 180 - 47

m<7 = 133°

✔️m<5 = 180 - (52 + 47)

m<5 = 180 - 99

m<5 = 81°

Answer:

A quadratic equation is some thing like

(x+2)^2

or

(x+2)(x+5)

In order to solve them, the most basic method is the FOIL method

F-First

O-Outside

I-Inner

L-Last

So for example

(x+2)^2

Which is basically

(x+2)(x+2)

So the first is the 2 Xs

(x+2)(x+2)

x*x=x^2

The outer is the x and the 2,

(x+2)(x+2)

2*x=2x

Now the Inner which is the 2 and the x

(x+2)(x+2)

2*x=2x

And finally the last  which is the 2 and the second 2

(x+2)(x+2)

2*2=4

Now add them all up

X^2+2x+2x+4

Combine like terms

x^2+4x+4

There you have it

Do the same with every other quadratic equation

Answer:28 dollar

Step-by-step explanation: 140 x (20/100)= 28 dollar

140-28= 112 the price after the sale

Answer: you will save $28.

Step-by-step explanation:

To find a percent of a number you have to turn the percent into a decimal. For example you would turn 20% into 0.20 then multiply this by 140. After doing this you will find out that 20% of 140 is 28.

Hope this helps ;)

Answer:

The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

Step-by-step explanation:

Given the rule

''y is 3 times the value of x".

It means

y = 3x

comparing with the slope-intercept form of the line equation

y = mx+b

where y is the slope and b is the intercept

so,

The slope of y = 3x will be: m = 3

The y-intercept of  y = 3x will be: b = 0

CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)

Taking two points

(0, 0)

(2, 6)

Finding the slope between (0, 0) and (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [6 - 0] / [2 - 0]

                = 6 / 2

               = 3

Thus, the slope of the line = m = 3

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function

y = mx+b

y = 3x+0

y = 3x

Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.

Also, the correct graph is attached below.

Answer:

It's the bottom right graph.

Answer:

286

Step-by-step explanation:

I dit 220+30%=286

Answer:

$286

Step-by-step explanation:

220 • 0.3 = 66

220 + 66 = 286

All the angles make a full circle which needs to equal 360 degrees.

Add all the angles together to equal 360:

X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360

Combine like terms:

9x -30 = 360

Add 30 to both sides:

9x = 390

Divide both sides by 9:

X = 390/9

X = 43.3333. ( 43 and 1/3)

Answer:

x = 43 1/3 degrees.

Step-by-step explanation:

All these angles add up to 360 degrees , so we have:

x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360

9x - 30 = 360

9x = 390

x = 390/9

= 43 1/3 degrees

Answer:

A = 16cm

B = 32cm

C = 8cm

D = Sorry the time I learned this I didn't learn it for fractions.

There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pie you can calculate the circumference.

The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.

The formula for working out the circumference of a circle is:

Circumference of circle = π x Diameter of circle

This is typically written as C = πd.

Answer:

d = 1

t = 16

Step-by-step explanation:

Television = t

DVD = d

4t + 6d = 70

2t + 5d = 37

2t + 5d = 37

2t = 37 - 5d

2t/2 = 37/2 - 5d/2

t = 18.5 - 5/2d

4t + 6d = 70

4(18.5 - 5/2d) + 6d = 70

74 - 10d + 6d = 70

-4d = -74 + 70

-4d = -4

-4d/-4 = -4/-4

d = 1

2t + 5d = 37

2t + 5(1) = 37

2t + 5 = 37

2t = 37 - 5

2t = 32

2t/2 = 32/2

t = 16

Check: d = 1; t = 16

4t + 6d = 70

4(16) + 6(1) = 70

64 + 6 = 70

70 = 70

2t + 5d = 37

2(16) + 5(1) = 37

32 + 5 = 37

37 = 37

Answer:

[tex]y = \frac{2}{3} x - 3[/tex]

Step-by-step explanation:

For the equation to be written in the form of y=mx+b, ensure that the y term is on one side of the equation and bring the rest to the other side. Then divide the whole equation by the coefficient of y, so that the resulting coefficient of y is 1.

2x -3y= 9

-3y= -2x +9 (-2x on both sides)

Dividing both sides by -3:

[tex]y = \frac{2}{3} x - 3[/tex]

Answer:

the ratio is 1:8

blank gallons of orange juice per 1 gallon of app

le juice is 1/8

8 gallon of apple juice = 1 gallon of orange juice

1 gallon of apple juice = 1/8 gallon of orange juice

1920 gallon of apple juice = 1/8 * 1920 gallon of orange juice

= 1/8 * 1920 = 240 gallon of orange juice

1 gallon of orange = 8 gallon of apple

6260 gallon of orange = 8 * 6260 gallon of apple

= 50080 gallon of apple juice

Answer:

DE = 14

Step-by-step explanation:

Since, DE is a Mid-segment of triangle ABC.

Therefore,

DE = 1/2 * AC

2 DE = AC

2(5x - 1) = 3x + 19

10x - 2 = 3x + 19

10x - 3x = 19 +2

7x = 21

x = 21/7

x = 3

DE = 5x - 1

DE = 5*3 - 1

DE = 15 - 1

DE = 14
