Sum of the ages of A and B is 55 years. If the ratio of their ages is 6:5. find their ages...
lys-0071 [83]

Answer:

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

Step-by-step explanation:

here's the solution : -

let their ages be 6x and 5x

and we know sum of their ages = 55

So, 6x + 5x = 55

=》11x = 55

=》x = 55 ÷ 11

=》x = 5

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

A bag contains five ping-pong balls numbered 1 to 5. Two balls are removed to form a two digit number. The smallest possible num
blsea [12.9K]

Answer:

\frac{11}{42} or 26.19%

Step-by-step explanation:

If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...

13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53

Therefore, the probability that the number formed is a prime would be \frac{11}{42} which if we divide and multiply the decimal by 100 we get the probability in percentage form.

\frac{11}{42} = 0.2619

0.2619 * 100 = 26.19%

Finally, we can see that the probability of this happening is 26.19%

A video game system and several games are sold for $ 648. The cost of the games is 3 times as much as the cost of the system. Fi
podryga [215]

First set up the equation.

x + 3x = 648

Then solve for x.

4x = 648

Divide both sides by 4.

x = 162.  So the answer for the system would be $162 and the price for the games would be $486.  Add the two up to check your work and you will get $648.  Hope this helped!

As part of a new fitness plan, Sabir walks on a treadmill at the same speed for 15 minuets every morning. The table shows the ca
Reil [10]
The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x
