Answer:

-600

Step-by-step explanation:

(-3*10⁴) * (2*10^-3)

= (-3*10000) * (2*0.01)

= (-30000) * (0.02)

= -600

So, the answer should be -600

Hope this helps!

Answer:

-60

Step-by-step explanation:

(-3 * 10⁴) * (2 * 10⁻³ ) = -3 * 2 * 10⁽⁴⁻³⁾

                                = -6 * 10¹

                                =  -60

Answer:

17.5 Km

Step-by-step explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km

Answer:

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Step-by-step explanation:

Equations

We are given some conditions applying to the internal angles on a triangle ABC.

The measure of angle A is 13 less than the measure of angle C.

The measure of angle B is 11 less than 4 times the measure of angle C

Let x = measure of angle C

The first conditions states:

[tex]m\angle A = x-13[/tex]

The second conditions states:

[tex]m\angle B = 4x-11[/tex]

The sum of all angles must be 180°, thus:

[tex]x - 13 + 4x - 11 + x = 180[/tex]

Simplifying:

6x -24 = 180

Adding 24:

6x = 204

Dividing by 6:

x = 204/6

x = 34

[tex]m\angle C = x = 34^\circ[/tex]

[tex]m\angle B = 4x-11 = 4*34-11 = 125^\circ[/tex]

[tex]m\angle A = x - 13 = 34 - 13 = 21^\circ[/tex]

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Answer:

D

Step-by-step explanation:

this equation is equivalent to y = -28, which is horizontal so it has a slope of 0

The domain and range of the function f(x)=28 is Domain: All real numbers Range: {-28}. The correct option is D.

The given function f(x)=-28 has a domain of all real numbers because the function can take any value of x. But, the range of the function is only -28. This is because for any input(x) the value of the function will remain the same which is equal to -28.

Hence, the domain and range of the function f(x)=28 is Domain: All real numbers Range: {-28}.

Answer:

  the listed sequences have no common difference(s)

Step-by-step explanation:

The differences in the first sequence are ...

  8, 10, -1, 19

These values are not equal, so there is no common difference.

__

The differences in the second sequence are ...

  -3, 3, -3, 3

These values are not equal, so there is no common difference.

The difference is the difference between a term value and the one before.

  1 -(-7) = 8

  3 -6 = -3

Answer:

The answer is -6

Answer:

Step-by-step explanation:

If -3/2 and 5 are solutions to the quadratic equation, hence the expression will give;

(x-(-3/2))(x-5) = 0

(x+3/2)(x-5) = 0

Compare the resulting expression with (ax+b)(x+c)=0, we can see that;

ax = x

divide both sides by x

ax/x = x/x

a = 1

b = 3/2

-5 = +c

c = -5

Hence a = 1,  = 3/2 and c = -5

Answer:

its not A just took the test

Step-by-step explanation:

The effect this scale factor has on the volume is that the volume will be 64 times larger. The correct option is B.

Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.

So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called a scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k².

to get each other corresponding quantities from their similar figures' quantities.

So the area of the first figure = k² × area of the second figure

Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or

The volume of the first figure = k³ × volume of the second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

Since the volume is the product of three linear quantities.

Therefore, if the scale factor of 4 is applied to the given prism then the volume of the prism will grow by 4³. Thus, we can write,

The volume of the scaled prism = 4³ ×Volume of the original volume

The volume of the scaled prism = 64 ×Volume of the original volume

Hence, the effect this scale factor has on the volume is that the volume will be 64 times larger.

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

The equation results of adding the two equations is 8x = 32.

The solution to the system is (4, 6).

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, A system of linear equations in variables 'x' and 'y'.

2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'

Reaaranging eqn(i) we have

3x + 2.5y = 27...(iii)

Adding (ii) and (ii) we have,

8x = 32.       (As + 2.5y and - 2.5y cancels)

x = 32/8.

x = 4.

Putting the value of 'x' in eqn(i) we have,

2.5y + 12 = 27.

2.5y = 15.

y = 6.

So, The solution to the system is (4, 6).

Answer:

They started shopping for cloths at 11:45 AM

Step-by-step explanation:

First of all we have to calculate the whole time that they spent in the mall starting from shopping.

They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:

[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]

as 30 minutes is equal to half hour so we used 0.5 in place of it.

Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.

[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]

Hence,

They started shopping for cloths at 11:45 AM

Answer:

A''(3/2, -3)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.

If a point A(x, y) is reflected over the x axis, the new point would be A'(x, -y).

If a point A(x, y) is dilated by a factor k, the new point would be A'(kx, ky).

Given that Trapezoid QUAD has vertices at Q(-4, 0), U(-2, 4), A(2, 4) and D(4, 0).  If the trapezoid is reflected over the x-axis to create trapezoid  Q'U'A'D', the vertices would be at Q'(-4, 0), U'(-2, -4), A'(2, -4) and D'(4, 0).

If trapezoid Q'U'A'D'is dilated by a factor of 3/4  respect to the origin to create trapezoid Q"U"A"D", the vertices would be at Q''(-3, 0), U''(-3/2, -3), A''(3/2, -3) and D''(3, 0)
