1.25 hours will it take them to paint a door.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Aaron can paint a door in 3 hours.
Anna can do the same job in 2 hours.
Since you have two painters for one door we can calculate the average of their combined times as
= (3 h + 2 h) /2
= ( 180 + 120) /2
= 300/ 2
= 150 minutes.
= 150/ 2
= 75 min
= 75/ 60
= 1.25 hours.
It would take nearly 1 hour and 25 minutes.

Katrina is going to order sweatshirts for her girls mentoring group. The sweatshirts will have the group logo printed on the front. Katrina asks two local companies to give her a price.
• MH Designs will charge $21.50 for each of the sweatshirts.
• Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.
Justify how to determine the number of sweatshirts Katrina would need to order from
each company for the costs to be the same.
Answer:
Katrina would need to buy 20 sweatshirts.
Step-by-step explanation:
The number of sweatshirts Katrina would need to order from each company can be determined by forming the linear equation in two variables.
Given :
Katrina is going to order sweatshirts for her girl's mentoring group.Katrina asks two local companies to give her a price.MH Designs will charge $21.50 for each of the sweatshirts. Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.
So, the cost for ordering the sweatshirt from the company MH Design is:
[tex]21.50x = c[/tex]
Now, the cost for ordering the sweatshirt from the company Print Rich is:
18y + 70 = c'
Given that the number of sweatshirts Katrina would need to order from each company for the costs to be the same. So :
21.5x = 18y + 70
Now, put the value of x and y so, that in the above equation, both sides become equal.

Explain how to get the variable alone in the equation. 3x = 24
Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Kai needs to replace the strip laminate that is glued to the vertical faces on a square tabletop. The tabletop is 1.69 m2. What length i laminate does he need
Area of a square = Side x Side (length x width)
A = 1.69 m²
Length = √area of square
L = √1.69 m²
L = 1.3 m
Check Work: 1.3² = 1.3 m x 1.3m
= 1.69 m²
Answer:
he needs 1.3 meters of laminate for the length
Step-by-step explanation:
area of a square = side multiplied by side (or length x width)
area = 1.69 m²
Length = √area of square
L = √1.69 m² or 1.3m

Use the second derivative test to find the relative extrema for f(x)=x^4-2x^2 + 3
If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:
f'(x) = 4x ³ - 4x
f''(x) = 12x ² - 4
Solve f'(x) = 0 to get the critical points of f(x) :
4x ³ - 4x = 4x (x ² - 1) = 0
→ x = -1, x = 0, x = 1
Check the sign of the second derivative at each of these points:
f'' (-1) = 8 > 0
f'' (0) = -4 < 0
f'' (1) = 8 > 0
These indicate the presence of
• two minima of f (-1) = 2 and f (1) = 2
• one maximum of f (0) = 3
which makes C the correct answer.
