how do i answer this question

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.

Answer:

60

Step-by-step explanation:

180-120= 60

a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.

Answer:

$12.60

Step-by-step explanation:

30% of 18 = 5.4

18 - 5.4 = 12.6

Answer is $12.60

Answer:

$12.60

Step-by-step explanation:

30% is just 0.3 of a number, do 100%-30% which gives you 70% or 0.7, 0.7 of 18 would be 12.6 or $12.60

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.

Answer:

64 (2) ^ n-1

Step-by-step explanation:

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

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

Answer: 0.41

Step-by-step explanation:

0.91 - 0.56 = 0.41

The salt left in the container is 0.41 grams.

Given that, 0.97 grams of salt is in a container and you use 0.56 grams.

We need to find how much salt is left in the container.

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.

Answer:

22/15=x

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.
