50 written as a product of its prime fac tors

1 answer:

7 0

Start by identifying any factor of 50 and then rewriting 50 to include that one factor and another:

50 = 5 * 10 5 is prime, but 10 is not. Thus, factor 10:

50 = 5 * 5 * 2 This is 50 as a product of its prime factors 5, 5 and 2.

7) Write the decimal number as a fraction
(over 1)
2.18 = 2.18 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 2.18 × 10 × 10 × 10 = 2180
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 2180 / 1000

Simplifying our fraction

= 2180/1000

= 109/50

= 2 9/50

8) $7 ^{-5} = \frac{1}{7^{5}}$

The graph below shows the speed of a car that is driven through a town and then on a major highway. During which of the followin

Varvara68 [4.7K]

Considering the graph of the velocity of the car, it is found that the interval in which it was stopped at a traffic light was:

Between 3 and 4 minutes.

<h3>When is a car stopped at a traffic light?</h3>

When a car is stopped at a traffic light, the car is not moving, that is, it's velocity is of zero.

In this problem, the graph gives the <u>velocity as a function of time</u>, and it is at zero between 3 and 4 minutes, hence the interval in which it was stopped at a traffic light was:

Between 3 and 4 minutes.

3x + 5y = -27<br> |-7x - 5y = 3

Ivanshal [37]

Answer:

(x, y) = (6, -9)

Step-by-step explanation:

Add the two equations to eliminate the y-variable:

(3x +5y) +(-7x -5y) = (-27) +(3)

-4x = -24 . . . simplify

x = 6 . . . . . . divide by -4

Substitute this value of x into the first equation and solve for y:

3(6) +5y = -27

5y = -45 . . . . . . . subtract 18

y = -9 . . . . . . . . . divide by 5

The solution to this system of equations is (x, y) = (6, -9).

Sanjit drives the 45 km distance between York and Leeds he then drives a further 42 km from Leeds to Blackpool

I am Lyosha [343]

Answer: His average speed for his total journey from York to Blackpool is approximately 61.41 km/h.

Step-by-step explanation:

$\text{ The average speed}=\frac{\text{Total distance covered}}{\text{Total time taken}}$

Since, The distance covered by him from York to Leeds = 45 km,

The speed when he covered this distance = 54 km/ h

Thus, the time taken by him in travelling from York to Leeds = 45/54 hours (Because, Time = Distance/speed)

Now, The distance covered by him from Leeds to Blackpool = 42 km,

The time taken by him in travelling from Leeds to Blackpool = 35 minutes = 35/60 hours

Hence, the total time taken by him in this journey

$=\frac{45}{54}+\frac{35}{60}=\frac{450+315}{540}=\frac{765}{540}=\frac{17}{12}$ hours

And, the total distance he covered= 45 + 42 = 87 km

Thus, His average speed

$=\frac{87}{17/12}= \frac{12\times 87}{17}=\frac{1044}{17}=61.4117647\approx 61.41\text{ km per hour}$
