Answer:
She sold 5.775 kilograms of pears at the farmer's market.
Step-by-step explanation:
Let's first determine the information that the question gives us, and what we need to find.
Given:
The farmer sold 7.7 kilograms of apples and pears
1/4 of the weight is apples
The rest of the weight is pears
Find:
Kilograms of pears that the farmer sold
Start by finding the fraction of the whole weight that was pears...
Now, find 3/4 of 7.7...
She sold 5.775 kilograms of pears at the farmer's market.
Answer:
36.51
Step-by-step explanation:
If Bailey ran four miles, then the time that is given for each of her miles should be added together to find out her total time.
9.05 + 8.24 + 10 + 9.22
You can break it down into chunks to make it easier for you:
9.05 + 8.24
= 17.29
___________
9.22 + 10
= 19.22
_________________________________________________
Then you can just add both values together to find out the total
_________________________________________________
17.29 + 19.22 = 36.51
Answer:
- x +y = 500
- 0.65x +0.95y = 0.75(500)
- solution: (x, y) = (300, 200)
Step-by-step explanation:
A system of equations for the problem can be written using the two given relationships between quantities of brass alloys.
<h3>Setup</h3>
Let x and y represent the quantities in grams of the 65% and 90% alloys used, respectively. There are two relations given in the problem statement.
x + y = 500 . . . . . . quantity of new alloy needed
0.65x +0.90y = 0.75(500) . . . . . quantity of copper in the new alloy
These are the desired system of equations.
<h3>Solution</h3>
This problem does not ask for the solution, but it is easily found using substitution for x.
x = 500 -y
0.65(500 -y) +0.90y = 0.75(500)
(0.90 -0.65)y = 500(0.75 -0.65) . . . . . . subtract 0.65(500)
y = 500(0.10/0.25) = 200
x = 500 -200 = 300
300 grams of 65% copper and 200 grams of 90% copper are needed.
Answer:
Well its actually really easy :) I am a girl lol
Step-by-step explanation:
We like it when you just talk and be there for us. Make jokes get to know the girl and just talk to her. A real relationship will take time for the connection to grow if you want a good long relationship don't rush to get into it with the person.
