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.
Hi there :) The best way to graph equations and to follow these 3 steps
<span>1. Locate the y-intercept on the graph and plot the point.
2. From this point, use the slope to find a second point and plot it.
3. Draw the line that connects the two points.
Please mark brainliest, thanks!</span>
#5,
it says that the angle on top is 221, so you subtract that from 360,
360-221= the rest..... 139
Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139
139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer
Answer:
42 units squared
Step-by-step explanation:
break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.
so the area of the rectangle = l x w
= 4 x 7
= 28
the area of the triangle is ( l x w )/2
= (7 x 2)/2
= 7
the other triangle is the same too
so the area of that is also 7.
now add all areas,
7+7+28 = 42
Answer:
it would be a 60%
Step-by-step explanation:
Divide 84 by 140, and you get .6
Hope this helps!!
