Answer:

90

Step-by-step explanation:

If 70% of a number is 63, we can call that number x and make the following equation:

0.7x = 63

Now we just need to solve for x:

x = 63/0.7

x = 90

So the original number is 90.

How do we know we’re right? If you do 70% of 90 (aka 0.7*90), you’ll get 63, so we know it’s correct.

The equation that represents the inequality in the graph is y < 2x + 2.

The solution of the system is (-1, -2).

At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.

To find the system of inequalities, first, we find the system of equations.

So, the first dotted line is passing through two points (-1, 0) and (0, 2),

then the equation of the line,

y - 0 = (2 - 0)/(0 + 1) (x + 1)

y = 2x + 2

From the diagram, the equation that represents the inequality in the graph is y < 2x + 2   ....(1)

Similarly, the equation of the second line is y ≤ 2x ...(2)

Now, the solution of the system is (-1, -2).

Therefore, the solution of the system is (-1, -2).

Answer:

[tex]y^2+x^2=9[/tex]

Step-by-step explanation:

Let's take a general point P(x,y). If there is a right angle at P then the slopes of the lines passing through AP and BP must be perpendicular.

Two lines of slopes m1 and m2 are perpendicular if:

m1*m2=-1

The slope of the line passing through P(x,y) and A(3,0) is:

[tex]\displaystyle m_1=\frac{y-0}{x-3}=\frac{y}{x-3}[/tex]

The slope of the line passing through P(x,y) and B(-3,0) is:

[tex]\displaystyle m_2=\frac{y-0}{x+3}=\frac{y}{x+3}[/tex]

Substituting in the equation:

[tex]\displaystyle \frac{y}{x-3}\cdot\frac{y}{x+3}=-1[/tex]

Operating:

[tex]\displaystyle \frac{y^2}{(x-3)(x+3)}=-1[/tex]

[tex]y^2=-(x-3)(x+3)[/tex]

[tex]y^2=-(x^2-9)[/tex]

[tex]y^2=-x^2+9[/tex]

The three statements that are true of a blackbody radiator are; A. It emits a range of wavelengths of EMR. C. It emits frequencies of EMR that depend on its temperature. D. It does not reflect much of the EMR it receives.​

A blackbody radiator is an object which absorbs all the electromagnetic radiation at varying frequencies and angles of incidence.

Blackbody radiators posses a cavity which does not allow heat to escape from the radiator.

The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, that are transverse waves formed by an electric field and a magnetic field perpendicular to it.

Therefore, we can conclude that the three statements that are true of a blackbody radiator are as listed.;

A. It emits a range of wavelengths of EMR.

C. It emits frequencies of EMR that depend on its temperature.

D. It does not reflect much of the EMR it receives.​

Hence, the three statements that are true of a blackbody radiator are option A, C and D.

Answer:

5,376in^3

Step-by-step explanation:

find the volume of the smaller box first

10×4×12 = 480in^3

find volume of bigger box

17×12×24 = 4,896in^3

add both volumes 4,896 +480 = 5,376in^3

Answer:

v = 5,376

Step-by-step explanation:

So the first thing we have to do is figure out the volume for the first part of the cube figure.

To do this we just multiply H x W x L =

In this case v = 4,896

Now we do the same thing with the other rectangular prism:

10 x 4 x 12 = 480

Now that we have the 2 volumes we add them together:

4,896 + 480 = 5,376

Hence the total volume = 5,376

The price increase is $6,027

The price of the next model is $55,027

Step-by-step explanation:

Find the cost of the next model by multiplying 49,000 by 1.123

49,000(1.123)

= 55,027

Find the price increase by finding the difference:

55,027 - 49,000

= 6,027

The price increase is $6,027

The price of the next model is $55,027

Answer  

1/5

Step-by-step explanation:

The slope of a perpendicular line is the negative reciprocal. Since y=-5x(m=-5), the slope is -(-1/5) which is 1/5

The slope of a line perpendicular to the line x - y = 6x is 1/5.

Here,

The equation of line whose equation is,

⇒x - y = 6x

We have to find the slope of a line perpendicular to the line x - y = 6x.

What is Equation of line?

The general equation of a straight line is,

y = mx + c

Where, m is the slope of the line.

Now,

The equation of line whose equation is,

⇒x - y = 6x

⇒ y = -5 x

Hence, the slope is -5.

The slope of a perpendicular line is the negative reciprocal.

So, The slope of a line perpendicular to the line x - y = 6x is,

⇒ [tex]-(\frac{1}{-5} )[/tex]

⇒ [tex]\frac{1}{5}[/tex]

The slope of a line perpendicular to the line x - y = 6x is 1/5.

Step-by-step explanation:

A = ab sinC / 2

sin C = (50 * 2) / (10 * 22) = 100 / 220 = 0.455

Given:

[tex]\theta_1[/tex] is located in IV Quadrant.

[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]

To find:

The value of [tex]\cos \theta_1[/tex].

Solution:

We have,

[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]

We know that,

[tex]\sin^2 \theta+\cos^2\theta=1[/tex]

So,

[tex]\sin^2 (\theta_1)+\cos^2(\theta_1)=1[/tex]

[tex]\left(-\dfrac{24}{25}\right)^2+\cos^2(\theta_1)=1[/tex]

[tex]\cos^2(\theta_1)=1-\dfrac{576}{625}[/tex]

[tex]\cos^2(\theta_1)=\dfrac{625-576}{625}[/tex]

Taking square root on both sides, we get

[tex]\cos (\theta_1)=\pm \sqrt{\dfrac{49}{625}}[/tex]

[tex]\cos (\theta_1)=\pm \dfrac{7}{25}[/tex]

[tex]\theta_1[/tex] is located in IV Quadrant. In IV Quadrant the value of cos is positive. So,

[tex]\cos (\theta_1)=\dfrac{7}{25}[/tex]

Therefore, [tex]\cos (\theta_1)=\dfrac{7}{25}[/tex].

Answer:

B

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -4/5,

[tex]y = - \frac{4}{5} x + c[/tex]

To find the y-intercept, substitute a pair of coordinates.

When x= -5, y= -4,

[tex] - 4 = - \frac{4}{5} ( - 5) + c \\ - 4 = 4 + c \\ c = - 4 - 4 \\ c = - 8[/tex]

Thus, the equation of the line is

[tex]y = - \frac{4}{5} x - 8[/tex]
