sarah meeham blends coffee for tasti delight. she needs to prepare 160 pounds of blended coffee beans selling for $4.97 per pound. she plans to do this by blending together a high quality bean costing $6.00 per pound and a cheaper bean at $3.25 per pound. to the nearest pound, find how much high quality coffee bean and how much cheaper coffee bean she should blend

Answers

Answer 1
Answer: Given:
h = high quality bean ; costs 6 per pound
c = cheaper bean ; costs 3.25 per pound

160 pounds of blended coffee beans at 4.97 per pound

h + c = 160

6h + 3.25c = 160(4.97)
6h + 3.25c = 795.20

h = 160 - c

6(160-c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
- 2.75c = 795.20 - 960 
- 2.75c = -164.80
c = - 164.80 / -2.75
c = 59.92 or 60 pounds

h = 160 - c
h = 160 - 60 
h = 100 pounds

Sarah must blend 100 pounds of high quality bean and 60 pounds of cheaper bean.

A baker baked some loaves of bread. 240 loaves were sold by the end of the day. The baker was then left with 9/25 of the number of loaves that were baked. How many loaves of bread did the baker bake on that day?

Answers

Answer:

The baker baked 375 loaves of bread that day.

Step-by-step explanation:

Let the baker baked a total of x loaves of bread.

240 loaves were sold by the end of the day.

The baker was then left with 9/25 of the number of loaves that were baked.

We get the equation:

x-240=(9x)/(25)

Solving for x;

=> 25(x-240)=9x

=> 25x-6000=9x

=> 25x-9x=6000

=> 16x=6000

x = 375

Therefore, the baker baked 375 loaves of bread that day.

in this case, 16/25=240 loaves that he sold
25/25 is how many loaves he started with, and 9/25 is what he now has
16/25 =240
divide bothe sides by the numerator(16) to get what 1/25 of his loaves equal
1/25=15
multiply both sides by 25 
the baker started with 375

Well the formula for this problem is A=3.14(pi) * radius * radius 
So multiply 3.14 times 9 times 9. first multiply 9 with 9 you get 81 then you multiply 81 times 3.14 which equals 254.34. When you find the formula to this kinds of equations it's very easy all you have to do is plug in the numbers. Hope this helps :) 

Need help with a problem. For some reason I can not seem to get it correct. Thinking my formula is wrong. Here's the problem:Assume that there are approximately 140x10^9 stars in our galaxy.
Our galaxy is 50,000 light years from the center to the edge, but just 1,000 light years thick. It's shaped like a thin disk or cylinder. If the stars were distributed equally throughout the galaxy, how many stars would you expect to find in one cubic light year?

I thought it would be Pi*r^2*l. Then divide that by the number of stars. What am I doing wrong? Thanks, been 20 years since I had to do math like this!

A gallon of paint can cover 150 square feet. Find how many galloti container of paint should be beate to paint 3 coats on each wall of a rectangular room with dimension feet by 14 feet and will shar 12-feet tall.

Answers

Area of the wall = 12 ft * 14 ft = 168 ft^2

Each wall is coated thrice with the paint.

Therefore, 168ft^2 * 3 = 504 ft^2

150ft^ 2 = 1 gallon paint.

Therefore 504 ft^2 requires

= 504/150

= 3.36 gallons of paint
