The military drone must ascend 12250 from its position of 3500ft above sea level feet so that it is vertically in the middle of the plane and the submarine.
To solve this problem we need to understand the concept of sea-level. The sea-level is defined as the average height of all water bodies of the earth. Below sea level is effectively taken as negative length and above sea -level is taken as positive length.
Let us consider the drone will have to ascend x feet to be vertically in between the plane and the submarine.
The submarine is 3500 feet below the sea level.
The plane is 35000 feet above the sea level.
Now we know that the drone is at a height of 3500 feet above the sea level.
Total distance between the drone and the ship=35000-(-3500)=38500ft
Middle point of the two=38500/2 = 19250 feet from the plane
Height above sea level for the drone should be=35000-19250=15750 ft
height of the drone=3500ft
The drone should ascend=15750-3500=12250 feet

The equation for the line parallel to the graph of y = 6x + -2 with the same y- intercept as the graph of y = 36x + 2 is written as y = mx + b. Determine the values of m and b. What is the value of m + b?
The values of m and b are 6 and 2 respectively and the value of m + b is 8.
The slope intercept of the straight line is used to find the equation of the straight line. The slope intercept formula requires knowing the slope of the line and the point of intersection of the line with the y-axis. Consider a line with slope "m" and y-intercept "b". The slope-intercept shape formula for a straight line with slopes 'm' and 'b' as y-intercept is given as y = mx + b.It is given that the equation y = mx + b ....(1) for the line parallel to the graph of y = 6x + -2 ...(2) means that slope of the equation y = mx + b which is parallel to the graph y = 6x + -2 is same i. e on comparing equation (1) and (2) , we get m = 6
On the other hand , the equation y = mx + b has the same y- intercept as the graph of y = 36x + 2 .....(3)
On comparing equation (1) and (3) , we get b = 2
Therefore , m + b = 6 + 2
= 8

The diameter of Jupiter at its equator is approximately 1.43 x 10 to the 5th power kilometers. Write this number in standard notation. An astronomer's infrared telescope is able to detect radiation with a wavelength of 0.000439 meters. Write this number in scientific notation.
The number in standard notation is 143,000.
The number in scientific notation is 4.39 x 10^-4
What is scientific and standard notation?
Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example:
• The number : 1 x 10² is equivalent to 100
• The number 5 x 10³ is equivalent to 500
When changing a number that is less than 1 to scientific notation, there would be a negative sign before the power.
0.000439 = 4.39 x 10^-4
In order to convert a number from scientific notation to standard notation, multiply the number by its power.
1.43 x 10^5
= 1.43 x 100,000 = 143,000

On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload. If he orders 2000 and Briggs will he have enough to complete a job require a 1900 bricks?
Yes, Briggs will have enough to complete a job requiring 1900 bricks. Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.
Given that On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload.
He orders 2000.
We need to see whether Briggs will have enough to complete a job requiring 1900 bricks.
How to find a percentage of a number?Example:
- 20% of M
= 20/100 x M
= 1/5 x M
- 25% of M
= 25/100 x M
= 1/4 x M
Find 4.5% of 2000.
= 4.5% x 2000
= 4.5 / 100 x 2000
= 4.5 x 20
= 45 x 2
= 90
The remaining bricks are:
= 2000 - 90
= 1910
We see that Briggs will have enough to complete a job requiring 1900 bricks.
1910 > 1900.
Thus, Briggs will have enough to complete a job requiring 1900 bricks.
Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.

Step-by-step explanation:
1 a) A restaurant is open 24 hours a day. The manager wants to divide the day into work shifts of equal length. The shifts w=should not overlap. All shifts durations should be a whole number of hours. Describe the different ways this can be done.
b) The manager turns on the restaurant's two neon signs at the same time. Both signs blink as they are turned o. One blinks every 9 seconds. The other sign blinks every 15 seconds. In how many seconds will they blink together again?
The possible answers for the restaurants are Three 8-hour shifts; four 6-hour shifts; six 4-hour shifts.
2. The seconds that they will blink together again is 45 seconds.
How to illustrate the information?Here we have to determine the factors of 24 for the shifts i.e. 1, 2, 3, 4, 6, 8, 12, 24 .
A 1-hour shift does not make much sense; most employers will also not use a 2-hour or 3-hour shift.
Restaurants typically do not use 12-hour shifts either, and employers do not use 24-hour shifts either.
Since both signs blink as they are turned on and one blinks every 9 seconds. The other sign blinks every 15 seconds. The least common multiple is 45.

What will the account be worth in 15 years?
Round your answer to the nearest cent.
In 15 years, the account will be worth $1896 if the 3.7% interest is compounded monthly on initial deposit of $1100.
What is compound interest?It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Given Data
A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
P=$1100
r =3.7%
t = 15years
Substitute the values in formula, A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
A= 1100(1+{3.7/100})¹⁵
A = 1100(1+0.037)¹⁵
A = 1100(1.037)¹⁵
A= 1100(1.724)
A= 1896.4
Round off to nearest cent - $1896
Hence, $1896 will the account be worth in 15 years

What exactly is compound interest?The interest you earn upon interest is known as compound interest. This may be demonstrated with simple math: if you have $100 and that it earns 5% interest every year, you will have $105 at the end of the first year. You'll have $110.25 by the end of the second year.
