A tank was 1/3 full of water. After 2950 ml of water were added, the tank was 3/4 full. Find the capacity of the tank in litres?

Ganezh [65]

C- capacity
c/3+2950=3c/4 the common denominator is 12.
4c+2950*12=3c*3
4c+35400=9c
35400=9c-4c
35400=5c
c=7080 ml =7.08l

What is the greatest prime you must consider to test whether 6971 is prime

tamaranim1 [39]

Answer:

Greatest prime is 83 to test 6971 is prime.

Step-by-step explanation:

To find : What is the greatest prime you must consider to test whether 6971 is prime.

Solution :

To determine whether it is prime or not we check it by taking the root and check the nearest prime factor of it

Step 1 - Take the square root of number 6971

$\sqrt{6971}=83.49$

Step 2- The last prime number before 83.49

Prime number is 83

Step 3 - Write all the prime number till 83 and if none of the digit divide 6971 then 6971 is prime.

So the only factors to check for 6971 are: 2, 3, 5, 7, 11, 13, 17, 19,, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83.

None of them divides the number

Therefore, 6971 is a prime number.

Greatest prime is 83 to test whether it is prime or not.

What number is 8% of 1,500?

Dima020 [189]

Answer:

120

Step-by-step explanation:

Solution for What is 8 percent of 1500:

8 percent *1500 =

(8:100)*1500 =

(8*1500):100 =

12000:100 = 120

Now we have: 8 percent of 1500 = 120

Question: What is 8 percent of 1500?

Percentage solution with steps:

Step 1: Our output value is 1500.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 1500 = 100%

Step 4: Similarly, x = 8%

Step 5: This results in a pair of simple equations:

1500 = 100% (1).

x = 8% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

1500 = 100%

x 8%

Step 7: Again, the reciprocal of both sides gives

x = 8

1500 100

x = 120

Therefore, 8% of 1500 is 120

When an opinion poll selects cell phone numbers at random to dial, the cell phone exchange is first selected and then random dig

Aliun [14]

Answer:

c. 8.25

Step-by-step explanation:

The given scenario corresponds to binomial experiment because

1. There are two possible outcomes i.e. each number can be working or not working.

2. On each dialing the probability of getting working cell number is p=0.55.

3. Cell phone numbers are randomly dialed so these are independent.

4. A pollster dialed 15 cell numbers i.e. n=15.

The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.

Mean of binomial distribution=E(x)=np

The mean number of calls that reach a working cell number=15*0.55=8.25

Thus, the mean number of calls that reach a working cell number=8.25
