Answer:

t=3.3*[tex]10^{-6}[/tex]

Step-by-step explanation:

t=[tex]\frac{S}{v}[/tex]

As

S=1m

v=3*[tex]10^{5}[/tex]ms^-1

t=[tex]\frac{1}{3*10^{5} }[/tex]

t=3.3*[tex]10^{-6}[/tex]

Answer:  According to the universe in which your light only moves at 3x10^5 meters/sec, it would take 3.333x10^-6 seconds to go 1 meter.  Where I live (Earth in the Milky Way Galaxy), light travels 3x10^8 m/s.  It only requires 3.33x10^-9 second.  So there . . .

Step-by-step explanation:

The speed of light is in units of meters/sec.   If it is 3x10^5 meters/sec, we can also write the inverse:

1 sec/3x10^5 meters  [It takes 1 sec to go 3x10^5 meters]

Do the division to find seconds per 1 meter:  3.333x10^-6 seconds.

-------

For Milky Way inhabitants, the division is 1 sec/3x10^8 meters, or 3.33x10^-9 second.  Time flies for them.

Answer:

On the coordinate plane, a line with a positive slope passes through the points (0, negative 1) and (1, 1).

Answer:

x^3/14

Step-by-step explanation:

When an exponent is raised to an exponent, you multiply the exponents. Therefore, the answer is x^2/7 * 3/4.

Answer:

[tex]y=\displaystyle -\frac{5}{3}x+7[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is [tex]\displaystyle -\frac{5}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle -\frac{5}{3}x+b[/tex]

Now, to solve for the y-intercept, plug in the point (3,2) and solve for b:

[tex]2=\displaystyle -\frac{5}{3}(3)+b\\\\2=-5+b\\b=7[/tex]

Therefore, the y-intercept of the line is 7. Plug this back into [tex]y=\displaystyle -\frac{5}{3}x+b[/tex]:

[tex]y=\displaystyle -\frac{5}{3}x+7[/tex]

I hope this helps!

Answer: if the width was not effected then the width is still 24 inches

if the area stayed the same, then

find area

area=legnth times width

288=12 times 24

so the new height./legnth =2

288=2 times width

divide by 2

144=width'

the new width =144

The volume is [tex] V=l\times w \times h[tex]

So

[tex]V=4x \cdot 5x\cdot (x^2+x+2)\\=20x^2\cdot (x^2+x+2)\\=20x^4+20x^3+40x^2.[/tex]

[tex]\frac{1}{3} (n+4)[/tex]

That is what the expression would be

Answer:

arc = 15π

Step-by-step explanation:

The arc is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{225}{360}[/tex] ( r is the radius )

given diameter = 24 then r = 24 ÷ 2 = 12

arc = 2π × 12 × [tex]\frac{5}{8}[/tex]

     = 24π × [tex]\frac{5}{8}[/tex]

     = 3π × 5

    = 15π

-4 × 10² is written in correct scientific notation.

Step-by-step explanation:

line a slope (x coefficient)= -2/3

Parallel lines have the same slope and will never intersect.

line b slope = -2/3

line equation =

y =mx + b

m = slope

y= -2/3 x + b

from the point given (-2,1)

x = -2

y = 1

1 = 4/3 + b

b = -1/3

b equation =

y = (-2/3)x - (1/3)

Answer:

8[tex]\frac{1}{7}[/tex] (in mixed fraction)

Step-by-step explanation:

4 ÷ [tex]\frac{5}{7}[/tex]

can also be written as

[tex]\frac{4}{1}[/tex] ÷ [tex]\frac{5}{7}[/tex]

[tex]\frac{4}{1}[/tex] ×[tex]\frac{7}{7}[/tex]       [tex]\frac{5}{7}[/tex] × [tex]\frac{1}{1}[/tex]   (to do the denominators same)

[tex]\frac{28}{7}[/tex] ÷ [tex]\frac{5}{7}[/tex]

= [tex]\frac{28/5}{7}[/tex]

= [tex]\frac{5.6}{7}[/tex]  

=  [tex]\frac{5.6}{7}[/tex] × [tex]\frac{10}{10}[/tex]  (to remove the decimal point)

= [tex]\frac{56}{7}[/tex]

= 8[tex]\frac{1}{7}[/tex] (in mixed fraction)

Answer:

x = -2/7 or

x = 6/7

Step-by-step explanation:

|7x-2| + 3 = -1  subtract 3 from both sides

|7x-2| = -4 now there are two probabilities

7x-2 = -4 or

7x-2 = 4 if first probability the value of x would be:

7x-2 = -4 add 2 to both sides

7x = -2 divide both sides by 7

x = -2/7 for the second probability the value of x would be:

7x-2 = 4 add 2 to both sides

7x = 6 divide both sides by 7

x = 6/7

Answer:

Smaller angle = 70 degrees

Step-by-step explanation:

Supplementary angles = add up to 180 degrees

let x = bigger angle

smaller angle = (x/2) + 15

x + (x/2) + 15 = 180

x + 0.5x + 15 = 180

1.5x = 165

x = 110

180 - 110 = 70

or

(x/2) + 15 = (110/2) + 15 = 55 + 15 = 70

Answer: the answer is like it is

Step-by-step explanation:

You just round the number in the tenths 0 is closer to 0 then to 10!
