Aaron can paint a door in 3 hours, and Anna can do the same job in 2 hours. Working together, how many hours will it take them to paint a door?
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.

The length of a rectangular dog park is 50 feet. The width is half the length. Decide if each set of steps could be used to find the perimeter of the dog park. Choose yes or no for each set of steps. answers: 1. Find the Width by dividing 50 by 2. Then add the length and width and multiply the sum to find the perimeter. 2. Find the Width by dividing 50 by 2. Then multiply the length by the width to find the perimeter. 3. Find the Width by dividing 50 by 2. Then add the length and the width to find the perimeter. 4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter. 5. Find the Width by dividing 50 by 2. Then add the sum of each length and the sum of each width to find the perimeter.
Answer:
4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes
Step-by-step explanation:
The length of a rectangular dog park is 50 feet. The width is half the length.
The formula for Perimeter is given as:
P = 2L + 2W
Length = 50 feet
Width = 50 feet/2
= 25 feet
P = 2(50) + 2(25)
P = 100 + 50
P = 150 feet
Hence, writing yes or no in front of each step in the options.
1. Find the Width by dividing 50 by 2. Then add the length and width and multiply the sum to find the perimeter = No
2. Find the Width by dividing 50 by 2. Then multiply the length by the width to find the perimeter. = No
3. Find the Width by dividing 50 by 2. Then add the length and the width to find the perimeter.= No
4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes
5. Find the Width by dividing 50 by 2. Then add the sum of each length and the sum of each width to find the perimeter = No

In a certain chemical, the ratio is zinc to copper is 4 to 15. A jar of the chemical contains 570 grams of copper, how many zinc does it contain
Answer:
zinc = 152 grams
Step-by-step explanation:
Ratio of zinc to copper = 4 : 15
Copper = 570 grams
zinc = x grams
Find x
Ratio of zinc to copper = x : 570
Equate both ratios
4 : 15 = x : 570
4/15 = x/570
Cross product
4 * 570 = 15 * x
2,280 = 15x
x = 2,280/15
= 152
x = 152 grams
zinc = 152 grams
Two of the tangents to a circle meet at Q, which is 25 cm from the center. The circle has a 7-cm radius. To the nearest tenth of a degree, find the angle formed at Q by the tangents.
Answer:
31.3
Step-by-step explanation:
Calculation to find the angle formed at Q by the tangents
First step is to use the tangent of the angle to calculate half the angle (A) at Q
Tan(A) =7-cm radius/25 cm
Tan A = 15.64
Since since we were told that two of the tangents to a circle meet at Q, Now let calculate the angle formed at Q by the tangents
Angle at Q(Tangents)=2*15.64
Angle at Q(aTangents)= 31.3
Therefore the angle formed at Q by the tangents will be 31.3

What is Law of Cosines?Law of cosines of triangle states that for three length of sides of the triangle, a, b and c opposite to the angles A, B and C respectively can be related as,
a² = b² + c² - 2bc cos(A)
Given a triangle QRS.
Given,
q = 73 inches
r = 40 inches
s = 51 inches
We have to find the measure of angle S.
By law of cosines,
s² = r² + q² - (2rq)cos(S)
51² = 40² + 73² - (2×40×73) cos (S)
(2×40×73) cos (S) = 4328
cos (S) = 0.741
S = 42.175° ≈ 42°
Hence the measure of angle S is 42°.

Complete Question
Kelvin finished 2/3 of his test in a 1/2 hour. Express this rate in hours per test.
Answer:
3/4 hours per test
Step-by-step explanation:
2/3 of his test = 1/2 hour
This rate in hours per test is calculated as:
x = 1/2 /2/3
x = 1/2 hour ÷ 2/3 test
x = 1/2 × 3/2
x = 3/4 hours per test
This rate in hours per test is given as 3/4 hours per test
