Answer:
x ≈ 14.7
Step-by-step explanation:
use pythagorean therorem
a^2 + b^2 = c^2
c is hypotenuse and we know the hypotenuse is 21
a^2 + b^2 = c^2
x^2 + 15^2 = 21^2
x^2 + 225 = 441
x^2 = 216
x = √216
x ≈ 14.7

suppose that verania and josimar are roommates that need to complete some household chores. vacuuming and washing dishes need to be done. they know from the last time they did these chores that it takes verania 2 hours to vacuum and 1 hour to wash dishes. it takes josimar 3 hours to vacuum and 2 hours to wash dishes. josimar says it does not matter which task each of them performs because verania is faster at both tasks.
It is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum.
Having an absolute advantage in both things does not mean that Verania has a Comparative advantage in both as well.
They should find out which activity they both have a comparative advantage in and focus on that. The activity that costs the least opportunity cost is the one they have a comparative advantage.
Verania
Opportunity cost of vacuuming = 2 / 1 = 2 hours of washing dishes
Opportunity cost of washing = 1/2 = 0.5 hours of vacuuming
Josimar
The opportunity cost of vacuuming = 3/2 = 1.5 hours of washing dishes
Opportunity cost of washing = 2/3 = 0.66 hours of vacuuming
Verania has a comparative advantage in washing dishes while Josimar has a comparative advantage in vacuuming.

A rectangular room is twice its breadth. It contains four windows of size 2 m x 1.75 m each and two doors of size 1 m x 3.5 m. If 24 pieces of tiles of size 2 mx 1.5 m each are required for tiling its floor and 41 pieces of 3D paper of size 3 m² each, are required for pasting on its 4 walls, find the height of the room.
The height of the room will be 4 meters
In the question, It is given that a room's four walls have to be covered by a 3-D paper of 3m² and 41 such papers are required for this. Also, we have been given that the room has 4 Windows of dimensions 2m * 1.75m each and 2 Doors of dimension 1m * 3.5m.
It is also stated that the tiling of the floor is done by tiles of dimension 2m * 1.5m each and 24 tiles are used for tiling.
Given that length is twice as breadth, Breadth b = x, and Length l = 2x
We know the Area of the rectangle: length * breadth
Area of tiles = 2 * 1.5 = 3m²
Area of 4 Windows = 2 * 1.75 *4 = 14m²
Area of 2 Doors = 2 * 1 * 3.5 = 7m²
On floor 24 tiles are used. So to calculate it we have : [tex]\frac{l*b}{3} = 24[/tex]
=> [tex]2x^{2} = 72[/tex] => x = 6
We get x = 6. Now, Breadth = 6meters, and Length = 12meters
For covering Four walls of the room with sheets, We will find out the Curved Surface Area of the room: 2h(l+b), where h is the height of the room. We also have to exclude the area of Four Windows and Two Doors for sheets. And a total of 41 pieces of sheets are required to cover it with an area of 3m² each. So, the formula will be, [tex]\frac{2h(l+b)-14-7}{3} = 41[/tex]
=> [tex]\frac{2h(18) - 14 - 7}{3} = 41[/tex] => 36h = 144
=> h = 4 metres
Hence, the height of the room will be 4 meters.

Solve the System of Equations using Substitution or Elimination. State your final
answer as an ordered pair (x,y) *
-3x + 10y = -15
5x - 7y = -4
Answer:
(- 5, - 3 )
Step-by-step explanation:
Given the 2 equations
- 3x + 10y = - 15 → (1)
5x - 7y = - 4 → (2)
Multiplying (1) by 5 and (2) by 3 and adding the result, eliminates the x- term.
- 15x + 50y = - 75 → (3)
15x - 21y = - 12 → (4)
Add (3) and (4) term by term to eliminate x, that is
29y = - 87 ( divide both sides by 29 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
- 3x + 10(- 3) = - 15
- 3x - 30 = - 15 ( add 30 to both sides )
- 3x = 15 ( divide both sides by - 3 )
x = - 5
solution is (- 5, - 3 )

subtract eight from both sides to leave the b variable on the left
b/2 = 14 - 8
b/2 = 6
multiply by 2 on both sides to leave b by itself
b = 6 * 2
b = 12
Answer:

Step-by-step explanation:
8 + b/2 = 14
b/2 = 14 -8

Fill in the blanks so that the equation has infinitely many solutions
5y + 6+ 7y = (blank) (6y + (blank))
solution
5y+7y+6= 12y+6
= 2(6y+3)
Answer:
2(6y + 3)
Step-by-step explanation:
for the equation to have infinitely many solutions, then both sides must be equal.
consider left side
5y + 6 + 7y ← collect like terms
= 12y + 6 ← factor out 2 from each term )
= 2(6y + 3)
then
5y + 6 + 7y = 2(6y + 3) ← has infinitely many solutions
Form A polynomial whose real zeros and degree are given.
What polynomial has zeros of -5,-1.2,5 and degree of 4?
The polynomial function has zeroes as given by x=0
In general, given zeroes of a polynomial function, a, b, c, and d, we can write the function as the multiplication of the factors
(x-a), (x-b), (x- c), and (x-d) then the degrees are 4
simply:
f(x)=(x-a) (x-b) (x- c) (x-d)
In this case, we can show that each of a, b, c, and d are zeroes of the function:
f(a)=(a-a) (a-b) (a-c) (a-d)
= (0) (a-b) (a-c) (a-d)
=0
f(b)=(b-a) (b-b) (b-c) (b-d)
=(b-a) (0) (b-c) (b-d)
=0
f(c)=(c-a) (c-b) (c-c) (c-d)
=(c-a) (c-b) (0) (c-d)
=0
f(d)=(d-a) (d-b) (d-c) (d-d)
=(d-a) (d-b) (d-c) (0)
=0
since the value of the function at x=a, x=b, c, and d are equal to 0, then the function
f(x)=(x-a) (x-b) (x- c) (x-d) has zeroes at a, b, c and d
with the generalized form, we can substitute for the given zeroes,
x=-5, x=-2,0and 5 where a=-5, b=-2, c=0 and x=5
f(x)=(x-(-5)) (x-(-2)) (x-0) (x-5)
simplifying gives:
f(x)=(x+5) (x+2) x(x-5)
from here, we can put it in standard polynomial form by foiling the right side:
f(x)=x^3+2x^2-25x-50
To double-check the answer, just plug in the given zeroes, and ensure the value of the function at those points is equal to 0.
f (-5) =x^3+2x^2-25x-50
=(-5)^3+2(-5)^2-2(-5)-50
f (-5) =0
f (-2) =(-2)^3+2(-2)^2-2(-2)-50
f (-2) =0
f (0) =0
f (5) =(5)^3+2(5)^2-2(5)-50
=0
Hence, the function has zeroes as given by x=0.

If he pays an additional $30.00 each month, he will have his balance paid off in 24 months. What percent of time will Haddad save by paying the extra $30.00 per month?
a)19%
b)24%
c)41%
d)59%
The percent of the time that Haddad will save by paying the extra $30.000 per month is d) 59%.
What is the percentage?A percentage is a unit in 100, a part of a whole, or a ratio of one variable to the bigger variable.
Percentages show the quantity or value of the independent variable that is contained in a dependent variable.
Data and Calculations:
Total months to pay off a debt = 58 months
The additional amount required to reduce the payment period to 24 months = $30 per month
The savings in time = 59% (58 -24/58 x 100).
Thus, the percent of the time that Haddad will save by paying the extra $30.000 per month is d) 59%.
