The sum of 7 consecutive odd numbers is 91. What is the sum of the two largest numbers in this set?

Answers

Answer 1
7 consecutive odd numbers...x, x + 2, x + 4, x + 6, x + 8, x + 10, x + 12

x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 + x + 12 = 91
7x + 42 = 91
7x = 91 - 42
7x = 49
x = 49/7
x = 7

x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13
x + 8 = 7 + 8 = 15
x + 10 = 7 + 10 = 17
x + 12 = 7 + 12 = 19

the sum of the 2 largest numbers is : 17 + 19 = 36 <==

A tree has a shadow of 30ft how tall is the tree? And a triangle has a right angle with a line of 2ft tall and the base of 5ft what do they have in common.

Answers

You need the angle of the line between the shadow and the line from the extreme of the shadow to the cup ot the tree.

Suppose that the angle is the same of a right triangle with a base of 5 ft and a tall of 2 ft.

=> 2/5 = x / 30ft => x = 30ft * 2 / 5 = 12ft

=> The tree is 12 ft tall.

And the two triangles are similar (they have same angles).

In what instance would you use the upside down U when doing interval notation

Answers

The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.

The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule mc014-1.jpg describes the relationship between the number of miles m and the total cost of the ride c. What is the charge for a 2.7-mile ride?

Answers

The cost of a ride depends totally on the number of miles traveled, plus a fixed charge of $1.75.

We can use the following notation to describe the rule:

C(m)=1.75 + 0.40 m   (dollars)

for example the cost of traveling 8 miles, is calculated by C(8):

C(8)=1.75+0.40*8=1.75+3.2 = 4.95  dollars.


the charge for a 2.7 mile ride is:

C(2.7)=1.75+0.40*2.7=1.75+1.08=2.83   dollars

A roulette wheel contains the integers 1 through 36, 0, and 00. suppose that you spin the wheel 6 times and that each time you bet on a single number. what is the probability (rounded to the nearest hundredth) that you win on at least one bet?

Answers

The probabability of winning on at least 1 bet is equal to 1 less the probaility of not winning on either of the 6 bets.

The probability of not wining on any bet is independent of winning or not winning on any of the bets, so the combined probability is calculated as the product of each individual probability.

Each indivitual probability of not winning the is:

(number of not winning outcomes) / (number of possible outcomes) = 37 / 38.

Then, the combined probability of not winning the six times is: (1/38)*(37/38)*(37/38)*(37/38)*(37/38)*(37/38) =(37/38)^6

Therefore, the probability of winning at least one bet is:

= 1 - (37/38)^6 ≈ 1 - 0.973684 ≈ 0.03.

Answer: 0.03.

Hi there!

I hope that helps!
Brainliest answer please :)
So the question asks to combine like terms. This means it wants you to add the terms that are the same. For example, if you have 2n and 3n, and a question asks you to combine like terms, you would add them together and you would have 5n. In this equation, we see the terms n, and we see the numbers. So we need to simplify so that the equation has only one term with n, and only one term with numbers. So I will split it into two parts: (8n - n) + (13 + 5). Now you can solve this and you are left with 7n + 18. Therefore your answer is 7n + 18. Hope this helps. :D Feel free to ask questions about my explanation or ask any other questions.

Charlie cannot remember how much he financed to buy his car. He does remember that his monthly payment is $200. His add-on interest rate was 9% and he made a total of 30 payments. Find the amount of his loan to the nearest penny.

Answers

First find the total payments
Total paid
200×30=6,000 (this is the future value)

Second use the formula of the future value of annuity ordinary to find the monthly payment.
The formula is
Fv=pmt [(1+r/k)^(n)-1)÷(r/k)]
We need to solve for pmt
PMT=Fv÷[(1+r/k)^(n)-1)÷(r/k)]
PMT monthly payment?
Fv future value 6000
R interest rate 0.09
K compounded monthly 12
N=kt=12×(30months/12months)=30
PMT=6000÷(((1+0.09÷12)^(30)
−1)÷(0.09÷12))
=179.09 (this is the monthly payment)

Now use the formula of the present value of annuity ordinary to find the amount of his loan.
The formula is
Pv=pmt [(1-(1+r/k)^(-n))÷(r/k)]
Pv present value or the amount of his loan?
PMT monthly payment 179.09
R interest rate 0.09
N 30
K compounded monthly 12
Pv=179.09×((1−(1+0.09÷12)^(
−30))÷(0.09÷12))
=4,795.15

The answer is 4795.15
Final answer:

The initial amount that Charlie financed to buy his car is approximately $5,364.93. This was calculated using the add-on interest loan formula with the provided monthly payments, interest rates, and number of payments.

Explanation:

The question is asking us to find out the initial amount that Charlie financed to buy his car, given that he made monthly payments of $200 at an interest rate of 9% over a total of 30 payments. This is a simple interest loan problem in mathematics, specifically dealing with add-on interest. To determine the original loan amount, we will use the formula for calculating the loan amount in an add-on interest loan. It is calculated by dividing the amount paid in total by the sum of one plus the product of the rate and time: Loan Amount = Total Payment / (1 + (Interest Rate * Time)) .

In this case, the total repayment made by Charlie is $200 * 30 = $6,000. The interest rate is 9% per year, but since he is making monthly payments we need to divide this by 12 to get the monthly interest rate, which is 0.0075. The time is 30 months. Substituting these values into our formula gives: Loan Amount = 6,000 / (1 + (0.0075 * 30)).

Hence, after calculations, the initial amount that Charlie financed to buy his car is approximately $5,364.93.

On may 31, the cash account of bottle's r us had a normal balance of $5,000. during may, the account was debited for a total of $12,200 and credited for a total of $11,500. what was the balance in the cash account at the beginning of may?

Answers

Final answer:

The balance in the cash account at the beginning of May was -$6,500.

Explanation:

The balance in the cash account at the beginning of May can be calculated by adding up the debits and credits for the month and subtracting them from the normal balance at the end of May.

In this case, the total debits for May were $12,200 and the total credits were $11,500.

To find the beginning balance, subtract the total credits from the normal balance:

Beginning balance = Normal balance - Total credits

Beginning balance = $5,000 - $11,500 = $-6,500

Therefore, the balance in the cash account at the beginning of May was -$6,500.

On two investments totaling $11,500, Peter lost 3% on one and earned 4% on the other. If his net annual receipts were $⁢201, how much was each investment?

Answers

Total amount of money invested - $11500
X +Y = $11500. ----------(1)
Total yearly interest for thetwo a/c is - $201
-0.03X + 0.04Y = $201
Form (1)
X = 11500 - Y
Substitute for X
-0.03(11500 - Y) + 0.04 Y = $201
-345 + 0.03Y + 0.04Y =201
0.07Y = 546
Y = 7800 at 4 %
Calculate X
X = 11500 - Y
= 11500 - 7800
=3700 at - 3%
Check
-0.03×3700 + 0.04 × 7800 = $201
-111 + 312 = $201
$201 = $201

Final answer:

Peter invested $3,700 at a 3% loss and $7,800 at a 4% gain. By setting up a system of equations and solving them, we determined the amount invested in each.

Explanation:

To solve the problem of how much was invested by Peter in each investment, we need to set up a system of equations. Let's call the amount invested at 3% loss x, and the amount invested at 4% gain y. The total amount invested is $11,500, so we have x + y = $11,500.

Peter's net annual receipts were $201, which comes from a loss of 3% on investment x and a gain of 4% on investment y. The equation for this would be -0.03x + 0.04y = $201.

Now we have a system of two equations:

-0.03x + 0.04y = $201

Adding (1) and (2) gives us:

0.03y + 0.04y = $546

Combining like terms, we get:

0.07y = $546

Dividing both sides by 0.07, we find that:

y = $7,800

Substituting y back into the first equation, we get:

x = $11,500 - $7,800 = $3,700

So, Peter invested $3,700 in the investment with a 3% loss and $7,800 in the investment with a 4% gain.

Which of the followings explains the difference between a regular subquery and a correlated subquery?

Answers

correlated means that they relate so probably this might help

A regular subquery is a standalone query that can be executed independently of the outer query and passes its result to the outer query. Conversely, a correlated subquery is linked with the outer query, executes for each row processed by the outer query, and may be slower due to these repeated executions.

The primary difference between a regular subquery and a correlated subquery resides in the way they operate and when they execute the control flow. A regular subquery is a standalone query, which means it can be executed independently of the outer query. Once it executes, it passes its result to the outer query.

On the other hand, a correlated subquery, as its name suggests, is 'correlated' with the outer query. It cannot be executed independently and must be run for each row processed by the outer query.

For example, if you use a correlated subquery to determine whether a record exists in another table, the subquery will run once for each record in the primary query. This can potentially be slower than a regular subquery due to the repeated executions.
