Step-by-step explanation:

Answer:

m(Au)=45.6 [gr] ; m(Cu)= 10.8 [gr].

Step-by-step explanation:

the masses of gold (Au), copper (Cu) and aluminium (Al) are:

0.76*60=45.6 (gr); 0.18*60=10.8 (gr.) and 0.06*60=3.6 (gr).

Answer:

x = 1 , x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

2x² - 5x + 3 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 3 = 6 and sum = - 5

The factors are - 2 and - 3

Use these factors to split the x- term

2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )

2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(2x - 3) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

15m/s

Step-by-step explanation:

we know that

v = u + at

= 0+ 3*5

=15m/s

The final speed of a car is 15 m/s.

Given that, a car begins from rest and accelerates at a rate of +3.0 m/s^2 for 5.0 seconds.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Here, the initial speed = u = 0

Now using v = u + at formula, we get

v = 0+ 3 × 5

=15 m/s

So, final speed is 15 m/s

Average speed is 15 m/s

Therefore, the final speed of a car is 15 m/s.

Answer: 21√10

Step-by-step explanation:

Answer:

Answer: 21√10

Or Decimal: 66.41

Since the probability of them winning is 5/14, the odds of them winning is 5:14.

Probability of the team losing = 9/14

Probability of the team winning will then be: = 1 - 9/14 = 5/14

It should be noted that in order for us to get the probability of then winning, we have to subtract the fraction from 1 which was what was done above.

Therefore, it can be deduced that since the probability of them winning is 5/14, the odds of them winning is 5:14.
