The amounts below show the change (measured in feet) in water level over four months. What is the average monthly change in water level?

3/4, -9/4, -11/4, 5/4

Answers

Answer 1

Answer:

The average change in water level is: -3/4

Step-by-step explanation:

The average is calculated by adding up all the values and then dividing the sum by total number of values.

Given values are:

3/4, -9/4, -11/4, 5/4

The sum of values will be:

[tex]=\frac{3}{4}+(-\frac{9}{4})+(-\frac{11}{4})+\frac{5}{4}\\=\frac{3}{4}-\frac{9}{4}-\frac{11}{4}+\frac{5}{4}\\=\frac{3-9-11+5}{4}\\=\frac{-12}{4}\\=-3[/tex]

Total number of values is 4

So,

[tex]Average = \frac{Sum}{Values}\\= \frac{-3}{4}[/tex]

Hence,

The average change in water level is: -3/4

Algebra 2

Answers

Answer:

13i, -13i

Step-by-step explanation:

x^2=-169

169=(13)^2

x^2=-(13)^2

the square root of -1 is i ( imaginary number )

(-13)^2=(13)^2 so x is 13i and -13i

Answer:

13i

Step-by-step explanation:

So I would solve for x

This is zero term factoring

This is a square root factor and 169's square root is 13.

However we need to factor -169

This is where imaginary numbers come in. i= Square root of -1

13i would be the answer

If a piggy bank consists of quarters and dimes.

There are 4 more dimes than quarters and the total

value of all the coins is $4.60. How many quarters

and dimes are there in the bank?

Answers

Answer:

There are 12 quarters and 16 dimes

Step-by-step explanation:

Firstly, we need to know that a quarter is worth $0.25 while a dime is worth $0.10

There are 4 more dimes than quarters;

So if there are x quarters, there are x + 4 dimes

From the question we can get;

0.25(x) + 0.1(x + 4) = 4.6

0.25x + 0.1x + 0.4 = 4.6

0.35x = 4.6-0.4

0.35x = 4.2

x = 4.2/0.35

x = 12

X + 4 = 12 + 4 = 16

Suppose that the world's current oil reserves is R = 1820 billion barrels. If, on average, the total reserves
is decreasing by 18 billion barrels of oil each year, answer the following:
A.) Give a linear equation for the total remaining oil reserves, R, in billions of barrels, in terms of t, the
number of years since now. (Be sure to use the correct variable and Preview before you submit.)
R
B.) 14 years from now, the total oil reserves will be
billions of barrels.
C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted (all
used up) approximately
years from now.
(Round your answer to two decimal places.)

Answers

Answer:

A. R = -18t + 1,820

B. 1,568 billions of barrels

C. approximately 101.11 years

Step-by-step explanation:

To make our equation, we'll use the form R = mt + b. M represents how many billion barrels of oil are being lost each year, which we know is 18 billion. So -18 will be our m. B is how many total barrels of oil there are, which is 1,820. So 1,820 will be our b. Now the equation looks like this:

R = -18t + 1,820

We can use this equation to answer Part B.

Replace the t with 14:

R = -18(14) + 1,820

Now solve for R:

R = -18(14) + 1,820

R = -252 + 1,820

R = 1,568

14 years from now, there will be 1,568 billions of barrels left.

To solve part C, we need to find how many years it will take for all of the oil to be used up. After it's all used up, the total amount of oil will be 0, so we can replace R with 0 and then solve for t:

0 = -18t + 1,820

Subtract 1,820 from both sides to isolate -18t:

0 - 1,820 = -18t + 1,820 - 1,820

-1,820 = -18t

Divide both sides by -18 to isolate the t:

-1,820/-18 = -18t/-18

101.11 = t

After approximately 101.11 years, all of the oil will be used up.

Bank A offers to pay you 3.5% annual interest if you deposit $500 for one year. Bank B will pay you 1.25% annual interest if you deposit $600 for one year. Which bank do you think will pay more to deposit your money over the course of a year?

Answers

The answer would be:
Bank A

Explanation:
Bank A gives 3.5% which is already more and you only have to pay a deposit of $500 for one year which is less than bank B.

Write the equation of the line that passes through the points (5,0) and (-6, -1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.

Answers

Answer:

The equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

Step-by-step explanation:

We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).

The general equation of point slope form is: [tex]\mathbf{y-y_1=m(x-x_1)}[/tex]

where m is the slope of line.

We need to know Slope m

Finding Slope m

Finding Slope m using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1[/tex]

Putting values and finding slope

[tex]Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}[/tex]

So , slope m is: [tex]\mathbf{m=\frac{1}{11}}[/tex]

Using point (5,0) and slope m =1/22 the equation of point-slope form is:

[tex]y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}[/tex]

So, the equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

Pumpkins at the pumpkin patch cost $3 for a small or $5 per large. On Saturday, they collected $105 and a total of 29 pumpkins sold. Create the two equations that would represent this system and type them in below: *

Answers

Let, number of small and big pumpkin are x and y.

So, mathematical equation is given by :

x + y = 29    ...1)

3x + 5y = 105     ...2)

Putting value of x from equation 1 to equation 2, we get :

[tex]3(29-y ) +5y=105\\\\2y = 18\\\\y = 9[/tex]

So, x = 20

Therefore, number of small and large pumpkins are 20 and 9 respectively.

Hence, this is the required solution.

Ben and his three friends were ordering pizza. They could spend at most $26. If a large
cheese pizza costs $22 and toppings are $0.65 each, how many toppings could they
get?

Answers

Answer:

6 toppings

Step-by-step explanation:

The t in this equation represents the amount of toppings.

22 + 0.65t = 26

-22 -22

0.65t = 4

0.65t/0.65 = 4/0.65

t = 6

They could get 6 toppings and the total would be $25.90.

You can get <1 from the given angle being a linear pair  to <1, so:

180= 80+ <1

100= <1

You can get <2 from being a linear pair to <1, so:

180 = 100 + <2

80 = <2

You can get <3 from being a linear pair to <2

180 = 80 + <3
