24 minutes. Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together:
Jannete repairs 1/60 refrigerator per minute.
Lisa repairs 1/40 refrigerator per minute.
Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute
thus it will take them 24 minutes
Answer:
4 is the real number in that complex number
Answer:
The length of the arc is 1.0467
Step-by-step explanation:
First of all to solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 3
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 3
c = 18.84
The length of the circumference is 18.84
Now we have to divide the 20° by the 360° that a circle has, to know what part of the circle it represents
20° / 360° = 1/18
Now we multiply this fraction by the circumference and obtain the length of the arc
1/18 * 18.84 = 1.0467
The length of the arc is 1.0467

Answer:
<u>6 cups</u> of whole milk is used for every teaspoon of salt.
Step-by-step explanation:
Given:
A recipe for ricotta cheese calls for 3/4 cup of whole milk for every 1/8 teaspoon of salt.
Now, to find the cup of whole milk should be used for every teaspoon of salt.
So, to get the cup of whole milk used we use unitary method:
For every 1/8 teaspoon of salt cup of whole milk used = 3/4 cup.
Thus for every teaspoon of salt cup of whole milk used = 3/4 ÷ 1/8.
(changing the division to multiplication the fraction reciprocals.)
Therefore, 6 cups of whole milk is used for every teaspoon of salt.
