If a car is traveling at 120 km/s within 120 min, what is its distance? (Remember: 60 seconds = 1 min. 120 km = 120,000 m) *

Answers

Answer:

[tex]d=864\times 10^6\ m[/tex]

Step-by-step explanation:

Given that,

Speed of a car, v = 120 km/s

It takes 120 minutes

v = 120000 m/s

t = 7200 s

We need to find the distance covered. Speed is given by :

v = distance/time

[tex]d=v\times t\\\\d=120000\ m/s\times 7200\ s\\\\d=864\times 10^6\ m[/tex]

So, the distance covered is [tex]864\times 10^6\ m[/tex].

how many real solutions will y=x^2 and y=-2x have? what are the solutions?

Answers

Answer:

there is none

Step-by-step explanation:

Answer:

No solutions

Step-by-step explanation:

Real number solutions only or real and complex solutions. A solution to the system:

y=-2x+2

y=x2-2x+4

is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that

-2x+2=x2-2x+4

solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.

How many unit cubes are required to create a larger cube with edge length 3 units?

Answers

Answer:

The unit cubes that are required to create a larger cube with an edge length of 3 units is:

27 cubes.

Step-by-step explanation:

To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:

To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:

If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.

Lila has $35.55. She buys a magazine for $3.15, a cookie for $2.20, and a shirt for $14.99. She also gets $5 from a friend. How much money does she have after the above transactions?
A)$10.21
B)$14.61
C)$16.51
D)$20.21

Answers

Answer:

$20.21

Step-by-step explanation:

$35.55 - $3.15 = $32.40

$32.40 - $2.20 = $30.20

30.20 - $14.99 = $15.21

$15.21 + $5.00 = $20.21

The answer is D

$35.55 - $3.15 = $32.4 $32.4 - $30.2 $30.2 - $14.99 = $15.21 $15.21 + $5 = $20.21
