How do subtract decimals?

To subtract decimals, write the numbers in a column, and make sure that the decimal points are aligned. To keep the decimal point in your difference, place a decimal point directly below the decimal points in the subtrends. Align the decimal point in the sum with the decimal point in the subtrends, and add a zero if necessary.

Now, 0.97-0.56=0.41 grams

Hence, the salt left in the container is 0.41 grams.

Step-by-step explanation:

Well first off we have to do the stuff in the parentheses-

3x(3+7)-42=2

9x+21x-42=2              Now we have to get x by itself

          +42  +42

9x+21x=44                Now add the like terms

30x=44                   Divide by 30

/30  /30                    30 chancels out

44/30                Simplify

22/15=x

Do the parenthesis first, 3+7=10, then do the exponent and get 256,multiply 3 times 10 and get 30, do 256 divided by 2 and get 128, finally do 30-128 to get 98.

Jerome parked his car for 4 hours each day for two days at two different parking lots. The cost of
parking at each parking lot is shown below.
Day 1 - $5.00 for the first hour plus $1.50 for every additional hour
Day 2 - $2.50 for the first hour plus $1.50 for every additional hour
What is the total amount Jerome spent to park his car at the parking lots after the two days?
A.$10.50
B.$13.50
C.$16.50
D.$19.50

ANSWER AND HAPPY NEW YEAR!!

Answers

the answer is c!!!!!!!

Answer:

C, or $16.50

Step-by-step explanation:

First of all, I added the prices of the first hours of both days. $5.00 + $2.50 = $7.50. Then, for every hour, the price for parking is $1.50. So, the easier way of doing this is adding the prices of both days together. $1.50 + $1.50 = $3.00.  So, she parked for a three hours each in parking lots 1 and two. So, that's 3 times $3 which is $9. $9.00 + $7.50 = $16.50.

What is the rule for the following geometric sequence? 64, 128, 256, 512

Answers

Answer:

64 (2) ^ n-1

Step-by-step explanation:

The rule for the given geometric sequence is 64(2)ⁿ⁻¹

What is a geometric sequence?

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

Its general term is arⁿ⁻¹. The value r is called the common ratio.

Given is a geometric sequence, 64, 128, 256, 512....., we need to find the rule for the sequence,

The general formula for geometric sequence, = arⁿ⁻¹

Finding the common ratio, r = aₙ₊₁ / a₁

r = 128 / 64 = 2

Therefore, we can write, the rule as,

aₙ = 64(2)ⁿ⁻¹

Hence, the rule for the given geometric sequence is 64(2)ⁿ⁻¹

there are n counters in a bag. 4 of the counters are red and the rest are blue. Ross takes a counter from the bag at random and does not replace it. he then takes another counter at random from the bag. the probability Ross takes two blue counters is 1/3. find the value of n​

Answers

Answer: n = 10.

Step-by-step explanation:

In the bag, we have n counters.

4 of the counters are red.

the rest are blue, then we have:

(n - 4) blue counters.

Now, the probability that Ross takes a blue counter from the bag is equal to the quotient between the number of blue counters (n - 4) and the total number of counters, n

Then the probability is:

p1 = (n - 4)/n

Now he draws another, and it must be blue again, then we can calculate the probability in the same way as above, but he already take a blue counter, so the number of blue counters is (n - 5) and the total number of counters is (n - 1)

The probability of this event is:

p2 = (n - 5)/(n - 1)

The joint probability (the probability that Ross takes two blue counters) is equal to the product of the individual probabilities, and we know that this is equal to 1/3, then we have the equation:

1/3 = ( (n - 4)/n)*((n - 5)/(n - 1))

Now let's solve this for n.

n*(n - 1)/3 = (n - 4)*(n - 5)

(n^2 - n)/3 = n^2 - 4*n - 5*n + 20

n^2 - n = 3*(n^2 - 9*n + 20)

n^2 - n = 3*n^2 - 27*n + 60

0 = (3*n^2 - n^2) - 27*n + n + 60

0 = 2*n^2 - 26*n + 60

The two solutions of this equation can be found with Bhaskara's equation:

[tex]n = \frac{-(-26) +- \sqrt{(-26)^2 - 4*2*60} }{2*2} = \frac{26+- 14}{4}[/tex]

Then the two solutions are:

n = (26 - 14)/4 = 3

This is not an option, because we know for sure that we have 4 red counters, then this option can be discarded.

The other solution is:

n = (26 + 14)/4 = 40/4 = 10

Then we have n = 10, 10 counters in total.
