Answer:
-2.75r+5r=p
and 900 for the profit and second part of the question.
Step-by-step explanation:
So first to solve this you need to plug in 400 for r
-2.75*400+5*400=p
you are then going to solve the -2.75*400
you get -1,100
you then are going to do the second part of the equation
yo get 2000
-1,100+2000 to get your profit of 900

A rectangular living room has a perimeter of 40 meters. Its area is 100 square meters. What are the dimensions of the living room?
In response to the question, we may say that So the dimensions of the rectangular living room are 10 meters by 10 meters.
What is rectangle?In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.
Let's denote the length of the rectangular living room as "L" and the width as "W".
Perimeter = 2L + 2W = 40
L + W = 20
We also know that the area of the living room is 100 square meters.
Area = L x W = 100
L + W = 20 (equation 1)
L x W = 100 (equation 2)
We can solve for one of the variables in terms of the other in equation 1:
[tex]L = 20 - W\\(20 - W) x W = 100\\20W - W^2 = 100\\W^2 - 20W + 100 = 0\\where a = 1, b = -20, and c = 100.\\W = (-(-20) + \sqrt((-20)^2 - 4 x 1 x 100)) / 2 x 1\\W = (20 + \sqrt(400 - 400)) / 2\\W = 10\\L + 10 = 20\\L = 10\\[/tex]
So the dimensions of the rectangular living room are 10 meters by 10 meters.

4). By applying cosine rule for angle R,
cos(∠R) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(33°) = [tex]\frac{x}{19}[/tex] [Equation]
x = 19cos(33°)
= 8.39
5). By applying sine rule,
cos(20°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
cos(20°) = [tex]\frac{15}{x}[/tex] [Equation]
x = [tex]\frac{15}{\text{cos}20}[/tex]
x = 15.96
6). By applying tangent rule,
tan(40°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(40°) = [tex]\frac{15}{x}[/tex] [Equation]
x = [tex]\frac{15}{\text{tan}40}[/tex]

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly. How much would Brody need to invest, to the nearest hundred dollars, for the value of the account to reach $34,000 in 13 years?
Answer:
$21,033
Step-by-step explanation:
The computation of the amount invested is shown below;
As we know that
Future value = Present value × (1 + rate of interest)^number of years
Now
Present value = Future value ÷ (1 + rate of interest)^number of years
where,
Rate of interest = 3.7% ÷ 12 = 0.3083333%
And, the number of years is = 13 × 12 = 156
So, the present value is
= $34,000 ÷ (1 + 0.3083333%)^156
= $21,033

Tom has arrive at the time of 259 248s.Find the number of Tom in Day,hour,Minute,Second
Answer:
3 days 0 hours 0 minutes 48 seconds
Step-by-step explanation:
Seconds = 259248 s
Number of days = Seconds given / 86400
Where 86400 = seconds in a day
The result is: 3 days remaining 48 seconds
Hours = Seconds Left / 3600 seconds.
Since the seconds left is 48, the hour = 0
Minutes = Seconds Left / 60 seconds.
Since the seconds left is 48, the minute = 0
Result:
3 days 0 hours 0 minutes 48 seconds

what two numbers multiply to equal -50 but adds up to equal 5
Answer:
10 and -5
Step-by-step explanation:
x + y = 5
xy = -50
y = 5 - x
x(5-x) = -50
5x - x^2 = -50
x^2 - 5x - 50 = 0
from there on we can solve the classic way
[tex]\Delta = (-5)^2 - 4\cdot1\cdot(-50) = 25 + 200 = 225\\\sqrt{\Delta} = 15\\x_1 = \frac{5 - 15}{2} = -5\\x_2 = \frac{5+15}{2} = 10\\y_1 = 5 - x_1 = 10\\y_2 = 5 - x_2 = -5[/tex]
Everything checks out.
Answer:
-5 × 10 = -50
-5 + 10 = 5
