Answer:

D

Step-by-step explanation:

when it's a power of the power we multiply the powers to get a single value for the power.

(6^(1/4))^4=6^(4*(1/4)) (4*(1/4)=1)

=6^1=6

so the answer is D

they amount of money are not the same

reason why;

the reason why its not the same is because 2x8x9=144 and 3x9x12=324 and the amount of money spent is different

The difference in price per cubic inch between the two sizes of cereal boxes is $0.0128.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The volume of the family-sized box of cereal is:

= 3 x 9 x 12

= 324 cubic inches

The volume of the regular-sized box of cereal is:

= 2 x 8 x 9

= 144 cubic inches

The price per cubic inch of the family-sized box is:

= 6 / 324

= 0.0185 dollars per cubic inch

The price per cubic inch of the regular-sized box is:

= 4.50 / 144

= 0.0313 dollars per cubic inch

The difference in price per cubic inch is:

= 0.0313 - 0.0185

= 0.0128 dollars per cubic inch

Therefore,

The difference in price per cubic inch between the two sizes of cereal boxes is $0.0128.

Answer:

3 2/5

Step-by-step explanation:

Add the distance she already ran, and subtract the sum from the total she needs to run.

Add two distances she ran:

3 1/2 + 2 1/2 = 3 + 2 + 1/2 + 1/2 = 5 + 1 = 6

Subtract sum from total:

9 4/10 - 6 = 3 4/10 = 3 2/5

Answer:

She needs to run 3 4/10 more miles

Step-by-step explanation:

If you add the amount she ran on Monday and the amount she ran on Tuesday you get 6 miles then subtract the 6 miles minus 9 4/10 you will get 3 4/10.

Answer:

Function 1 has the greatest rate of change.

Step-by-step explanation:

The rate of change is also known as the slope.

Slope is rise over run: change in y over change in x.

Function 1's slope: 3 / 2

Function 2's slope: (0 - (-4)) / (5 - (-5)) = 4/10 = 2/5

3/2 > 2/5

Function 1 has the greatest rate of change.

Answer:

52 years

Step-by-step explanation:

Let

Your age = x

3 times your age = 3 * x

= 3x

The equation can be written as:

400 - 3x = 244

400 - 244 = 3x

156 = 3x

Divide both sides by 3

x = 156/3

x = 52

Therefore,

Your age is 52 years

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

(1)

Here m = 2 and (a, b) = (- 1, 3 ) , then

y - 3 = 2(x - (- 1) ), that is

y - 3 = 2(x + 1)

(2)

Here m = - 5 and (a, b) = (4, 0 ) the coordinates of the x- intercept

y - 0 = - 5(x - 4) , that is

y = - 5(x - 4)

Answer:

18 times  a green bead is drawn

Step-by-step explanation:

There are 20 beads in the basket.  The probability of picking a green bead is 6/20 = 3/10.  That means that a green bead would be picked 3/10 of the time.

So, 3/10(60) = 18 times  a green bead is drawn

Answer:

N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28

Step-by-step explanation:

Using variables N=natalies age and F=Freds age

N+F=42 ----> N=42-F (take this and plug it into the other equation)

F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]

-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]

So N+28=42 or N=14.

Answer:

[tex]L^{2} + W^{2} = d^{2}[/tex]

d = 31.6

Step-by-step explanation:

[tex]L^{2} + W^{2} = d^{2}[/tex]

[tex]30^{2} + 10^{2} = d^{2}[/tex]

[tex]d^{2}[/tex] = 900 + 100

   =  1000

d = [tex]\sqrt{100}[/tex] = 31.6

Answer:

{-3, 5}.

Step-by-step explanation:

y = x + 8

x + y = 2

Substitute y = x + 8 in the second equation:

x + x + 8 = 2

2x + 8 = 2

2x = -6

x = -3

Now plug this into the first equation

y = -3 + 8 = 5.

y=15x+50 it should look something like that

Answer:

Y=2x^2

Step-by-step explanation:

The following equations represent a parabola with vertex (0,0): y=2x², x=-2y² and x=2y².

The quadratic function can be represented by a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

A parabola also can be represented by a quadratic equation. The vertex of an up-down facing parabola of the form ax²+bx+c is [tex]x_v=\frac{-b}{2a}[/tex] . Knowing the x-coordinate of vertex, you can find the y-coordinate of vertex.

The another form for describing a parabola is [tex]4p\left(x-h\right)=\left(y-k\right)^2[/tex], where h and k are the vertex coordinates.

You should analyse each one of the options, considering the equations that can be represented a parabola.

Letter A - y=2x²

The coefficients of the quadratic equation are:

a=2, b=0, c=0

Then,

[tex]x_v=\frac{-b}{2a}\\ \\ x_v=\frac{-0}{2*2}=0[/tex].

If x-coordinate of vertex is equal to 0, from y=2x²you can:

[tex]y_v=2x^2\\ \\ y_v=2*0^2=0[/tex]

Therefore, the given equation ( y=2x²) represents a parabola with vertex (0,0).

Letter B - x=-2y²

From equation [tex]4p\left(x-h\right)=\left(y-k\right)^2[/tex], you can rewrite the given equation parabola for vertex (0,0) in:

[tex]4p(x-0)=(y-0)^2\\ \\ 4*\frac{-1}{8} x=y^2\\ \\ \frac{-1}{2} x=y^2\\ \\ x=-2y^2[/tex]

Therefore, the given equation ( x=-2y²) represents a parabola with vertex (0,0).

Letter C - x=2y²

From equation [tex]4p\left(x-h\right)=\left(y-k\right)^2[/tex], you can rewrite the given equation parabola for vertex (0,0) in:

[tex]4p(x-0)=(y-0)^2\\ \\ 4*\frac{1}{8} x=y^2\\ \\ \frac{1}{2} x=y^2\\ \\ x=2y^2[/tex]

Therefore, the given equation ( x=2y²) represents a parabola with vertex (0,0).

Letter D - y=-2

The degree of equation is not equal 2. Therefore, it does not represent a parabola.

Only the equations of letter A, B and C represent a parabola with vertex (0,0). See the attached image.

Answer:

Step-by-step explanation:

Remark

Cos(y) = adjacent Side / hypotenuse

y = 51 degrees

adjacent = 10

Solution

Cos(51) = 10/x              Multiply both sides by x

x cos(51) = 10               Divide by Cos(51)

x = 10 / cos(51)

Cos(51) = .6293

x = 10/0.6293

x = 15.89

Answer:

13 km

Step-by-step explanation:

By Triangle Inequality Theorem: The sum of two smallest sides is greater than the third side.

Small Values of X:

X + 26 > 38

X > 38 - 26

X > 12

If we know that 38 km is the longest side, then the sum of other two sides must be greater than 38 km. Therefore the minimum value of X is 13 km.
