Rashad compiled a list of fixed expenses and noted his total expenses for last month.
Digiron [165]

The equation that represents the variable expences for the february is

x+ $1943.48 = $3,291.74

The linear equation is an equation where highest degree of the variables is 1.

As we know Total expenses include fixed as well as variable expenses.

Total Expenses = Variable Expenses +Fixed Expenses

⇒ Variable Expenses = Total Expenses - Fixes Expenses

Hence to Determine variable expenses Rashad needs we have to subtract his fixed expenses from his total expenses for the month.

Here, given that all February fixed expenses amount are

For rent, expenses are $1,150.00

For car loan expenses are $348.00

For internet, expenses are $46.14

For a student loan, expenses are $399.34

So the total amount of fixed expances are= rent expences+ car loan expences+ internet expences+ student loan expences = $1150+ $348+ $46.14+ $399.34 =$1943.48

Given, The total February expanses are $3,291.74.

Let;s assume the variable expenses is x

As we know

Total Expenses = Variable Expenses +Fixed Expenses

Then the linear equation will be

⇒ x+ $1943.48 = $3,291.74

solving for x i.e. Variable Expenses =  $3,291.74-$1943.48

⇒ Variable Expenses =  $1348.26

Therefore The equation that represents the variable expences for the february is   x+ $1943.48 = $3,291.74

Jamal will slice a right circular cylinder into to congruent pieces. Which two-dimensional plane section could result from the s
Debora [2.8K]

Answer:

1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Step-by-step explanation:

Given: Jamal Sliced aright circular cylinder into congruent pieces.

To find: Shape of Two-Dimensional plane section obtained after slicing.

We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.

By doing this we get small pieces of cylinders of equal height and equal radius.

Base and top remains same that is circular in shape.

Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.

Scientists on an oceanographic research vessel board a miniature submarine when it is at an elevation of 2 meters above the ocea
svetoff [14.1K]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

The ocean floor directly beneath the boat is at a depth of = 180 meters

Submarine is at an elevation when it is above the ocean's surface = 2 meters

Total distance submarine needs to descends at a constant rate = 180+2=182 m

Rate of submarine descends = 0.4 meters per second.

Time taken by a scientist spend descending after boarding the submarine is given by

Time=\frac{Distance}{Speed}\\\\Time=\frac{182}{0.4}\\\\Time=455\ seconds

so, it must be less than 455 seconds.

therefore, it becomes x<455.

Hence, Option 'A' is correct.

Please help. 50 Points.
Ronch [10]

Answer:

0.8745.

Step-by-step explanation:

P(success) = 0.09 and P(failure) = 1 - 0.09 = 0.91.

P( at least 6 failures) = P( less than 2 successes)

= 7C0 (0.09)^0 (0.91)^7 + 7C1 (0.09)(0.91)^6

=  0.5168 + 0.3577

= 0.8745.
