Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Answer:

2.25 or 2 1/4

Step-by-step explanation:

Easy. you add them like regular numbers. 1/4 + 2 = 0.25 + 2 =2.25 and/or 2 1/4

Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit

Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

= -12+3 degrees Fahrenheit

= -9 degrees Fahrenheit

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Answer: 3rd option

Step-by-step explanation:

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1

Answer:

 =  4

Step-by-step explanation:

Subtract  15 from both sides of the equation

6+15=39

6+15−15=39 − 5

Simplify

6=24

Divide both sides of the equation by the same term

(6=24)/6

Simplify

=4

Answer:

8[tex]x^{2}[/tex] + 3 + -6x

Step-by-step explanation:

First we need to find the like terms so that we could add them. In this case the like terms are,

1. 6x , -2x , -10x

So, these are the only terms that we can add in this expression.

Hence,

=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)

=> 8[tex]x^{2}[/tex] + 3 + -6x

And this is as simple as this expression can go until we find the value of "x" which is not yet told.

Hope my answer helped.

Answer:

3 rd one

Step-by-step explanation:

The conic section represented by the given equation is Circle.

Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.

Standard form of a circle is,

(x - h)² + (y - k)² = r²

where, (h, k) is the center of the circle and r is the radius of the circle.

Expanding, we get,

x² - 2hx + h² + y² - 2ky + k² = r²

x² - 2hx + y² - 2ky + (h² + k² - r²) = 0

The given equation is,

5x² – x + 5y² – 3y + 4 = 0

This is same as the standard form of the circle.

Hence the given equation is that of a circle.

Answer:

angle 1 is = 124 angle 2 is = 56

Step-by-step explanation:

supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.

ok sweetheart so basicaly what u do is...

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator

Answer:

This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".

Step-by-step explanation:

This is the Exact sample response,

Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.

Answer:

$43.92

Step-by-step explanation:

1st year:

30 x 10% = 3

30 + 3 = 33

2nd year:

33 x 10% = 3.3

33 + 3.3 = 36.3

3rd year:

36.3 x 10% = 3.63

36.3 + 3.63 = 39.93

4th year:

39.93 x 10% = 3.99

39.93 + 3.99 = 43.92

Answer:

x=28°

Step-by-step explanation:

2x+3x-10+50=180

5x+40=180

5x=180-40

5x=140

x=140/5

x=28°

The angle measure of a triangle are shown in the diagram.

What is the value of x?

As, In a triangle measure of all three angles is always 180°.

[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]

[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]

[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]

[tex] \sf : \implies 40 + 5x = 180\degree[/tex]

[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]

[tex] \sf : \implies 5x = 140\degree[/tex]

[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]

[tex] \sf : \implies x = 28\degree[/tex]

[tex] \large \underline{\boxed{\bf{x = 28\degree}}}[/tex]

Hence, value of x is 28°.

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2
