Number 1. Write An Explicit Formula For The Nth Term. Correct Answer Will Get Brainliest

Answers

Answer 1
Since the 11th term is 78 and the difference is -9, that means when we go down terms we add 9 and if we go up terms we subtract 9. Since 11-1=10, we can multiply 9 by 10 to get 90 and add that to 78 to get 168 as our first term. Since we subtract 9 for every number from there, we can have 168-9(n-1). We have n-1 due to that the first term is 168, and we want to subtract 9 from each one. If we had it as 168-9n, the second term would be 168-18 when it should be 168-9. We can also add 9 to 168 to get 177 and have it as 177-9n due to that we start at the 0th term. This works due to that we are multiplying -9 by the nth value and adding that to 177

what is( ×+4 /6)=(18/12)

Answers

First subtract 4/6 from each side of the equation: (x + 4/6 - 4/6) = (18/12- 4/6) =
x = 18/12 - 4/6. Simplify each fraction and 18/12 simplified by 6 will be 3/2 and 4/6 simplified by 2 would 2/3. The equation would now be x = 3/2 - 2/3. The least common denominator would be 6 so when converted the equation would now be 9/6 - 4/6 = 5/6 so x = 5/6. You can check your answer by substituting x in the original equation with 5/6 so it would be (5/6 + 4/6) = (18/12) and 5/6 + 4/6 = 9/6 and when expressed as a mixed number and simplified it would equal 1 1/2 and 18/12 simplified as a mixed number and simplified would equal 1 1/2.

A crane cable can support a maximum load of 20,000 kg. If a bucket has a mass of 4,000 kg and gravel has a mass of 1,500 kg for every cubic meter, how many cubic meters of gravel (g) can be safely lifted by the crane?

Answers

Alright, so we have a max of 20,000 kg. There is already 4000 on it, so we can subtract 4000 by 20000 to get 16000. We need to figure out how many times 1500 goes into 16000 to figure out the cubic meters, which is 16000/1500=10+2/3

Answer:

10.67 kg of gravel can be safely lifted by the crane

Step-by-step explanation:

Maximum load that a crane can support = 20000 kg.

Bucket has a mass = 4000 kg

Gravel has a mass = 1500 kg for every cubic meter.

Let the volume of gravel is = g cubic meter

Therefore, mass of the gravel = 1500g kg

Now we form an equation to show the weight that the crane cable can support

Mass of Bucket + mass of Gravel = Total mass that a lift can support

4000 + 1500g = 20000

1500g = 20000 - 4000

1500g = 16000

[tex]g=\frac{16000}{1500}[/tex]

g = 10.67 kg

Therefore, 10.67 kg of gravel can be safely lifted by the crane.

Find the inverse of f(x)= -x + 3

Answers

Let g the inverse function of f.

The most important property of g and f being inverses of each other, is that 

g(f(x))=x,      also f(g(x))=x

so, what one function 'does' to x, the other 'undoes' it.



Thus, we have:

f(g(x))=x      and alos   f(g(x))= -g(x)+3, from the rule


thus : 

-g(x)+3=x

-g(x)=x-3

g(x)=-x+3


check: f(g(x))=f(-x+3)=-(-x+3)+3=x-3+3=x


Answer: the inverse of f is g, such that g(x)=-x+3

Thirty-five states in a country have four-star hotels. Assume the country has 50 states. (a) What fraction of the states can claim at least one four-star hotel?​ (b) How many states do not have a​ four-star hotel?​ (c) Write the fraction of states without a​ four-star hotel.
a. The fraction of states with a​ four-star hotel ........ ​(Simplify your​ answer.)

Answers

(a) 7/10
the portion of states that have a four star hotel compared to how many states there are uses the fraction 35/50. You must simplify this, and to do this you find the greatest value with can divide the numerator and the denominator. This is 5. 35/5=7, and 50/5= 10, therefore, 7/10

(b) 15
simply subtract the number of states which have a four star hotel from the total number of states

(c) 3/10
this is the same logic as (a). use the answer you got from part b, and simplify the fractions 

The fraction of states with at least one four-star hotel is 7/10, 15 states do not have a four-star hotel, and the fraction of states without a four-star hotel is 3/10.

Answer to Student's Question

(a) To find the fraction of states with at least one four-star hotel, we divide the number of states with a four-star hotel by the total number of states. Therefore, the fraction is 35/50, which simplifies to 7/10.

(b) To determine how many states do not have a four-star hotel, we subtract the number of states with a four-star hotel from the total number of states: 50 - 35 = 15. So, there are 15 states without a four-star hotel.

(c) Finally, the fraction of states without a four-star hotel is the number of states without such hotels divided by the total number of states. This is 15/50, which can be simplified to 3/10.

what is 3(7x-6)<-81?

Answers

Hey there! How are you doing today?

3(7x - 6) < -81

First, we need to apply the Distributive Property to the left side of the inequality.
This mathematical term means to multiply the number or variable outside of the parenthesis to all numbers and/or variables on the inside of the parenthesis.

Here's an example;

3(2 + 1)
Multiply the outside number by all inside numbers.
3(2) + 3(1)
Multiply.
6 + 3
Simplify the expression.
9.

Now that we've explained our concept for distributing, let's apply what we now know to our current problem.

3(7x - 6) < -81

Apply the Distributive Property to the left side of the inequality.

3(7x) + 3(-6)
Multiply.

21x - 18

We now have:

21x - 18 < -81

Now we need to isolate the variable. To do this, we need to make sure that 'x' is by itself. Since x is being subtracted by 18, we need to apply the opposite order of operations to both sides of the inequality.

Add 18 to both sides to isolate the variable.

21x < -63

We now need to solve for x. To solve for x, we need to divide both sides by 21, as iur variable is being multiplied by 21.

We are now left with:

x < -3

This is your final solution to your inequality.

Mark draws one card from a standard deck of 52. he receives $ 0.35 for a heart, $ 0.55 for a jack and $ 0.85 for the jack of hearts. how much should he pay for one draw

Answers

he should pay $0.58 for one draw

To find out how much Mark should pay for one draw, calculate the expected value by multiplying the payouts for a heart, a jack, and the jack of hearts by their respective probabilities. Sum these values to find the amount Mark should pay per draw to make the game fair, which is $0.135.

To determine how much Mark should pay for one draw from the deck of 52 cards, we need to calculate the expected value (EV) of one draw. The EV is calculated by multiplying each outcome by its probability and summing these products.

The deck has 13 hearts, so the probability of drawing a heart (excluding the jack of hearts) is 12/52 or 3/13. Drawing any jack other than the jack of hearts has 3 possible outcomes in the remaining 51 cards; the probability is 3/52. The jack of hearts is a single card with a probability of 1/52. The remaining 36 cards are neither hearts nor jacks and yield no payout.

The EV is calculated as follows:

(12/52 × $0.35) for a heart

(3/52 × $0.55) for a jack

(1/52 × $0.85) for the jack of hearts
Adding these up we get: (3/13 × $0.35) + (3/52 × $0.55) + (1/52 × $0.85) = $0.13538. To ensure the game is fair and the host neither loses nor gains money in the long term, Mark should pay $0.135 per draw.

What is the value of the x-determinant for the system shown?

(A.) -22
(B.) -12
(C.) -2

Answers

The Value if the x deteminant for the system shown is -2 so its C

Final answer:

The value of the x-determinant for the system of equations is (C) -2, which is found by evaluating the determinant of the system's coefficient matrix.

Explanation:

To find the x-determinant for the system of equations given below:

x - y = 10

We can set up the coefficient matrix for these equations:

Matrix [A] =
| 1  1 |
| 1 -1 |

The determinant of this matrix is calculated by multiplying the diagonal elements and then subtracting the product of the off-diagonal elements. Hence, the determinant (det A) = (1)(-1) - (1)(1) = -1 - 1 = -2.

Therefore, the value of the x-determinant is (C) -2.

The Hamptons family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute. Define the input and output in the given scenario

Answers

The input is any variable which goes into the system. In this case there is no input.

 

While the output is any variable going out of the system. In this case the output is the amount of water which leaked out.

Answer:

The number of minutes represents input and remaining water represents output.

Step-by-step explanation:

Given,

The original quantity of the water in the tank = 10,450 ml,

Also, the quantity of the water leaked per minute = 270 ml,

Thus, the quantity water leaked in x minutes = 270x

∵ Remaining water in the tank ( say y ) = Original water - leaked water

y = 10450 - 270x,

Which is the equation that shows the given scenario.

In this equation, x represents the input value and y represents the output value,

Hence, the number of minutes represents input and remaining water represents output.
