ankoles [38]

Answer:

Slope = 3

Step-by-step explanation:

the points (5,8) and (9,20)

A point is always written in the form (x, y)

(5,8) and (9,20) is in the form (x1, y1)  and (x2, y2)

Slope =( y2 - y1) / (x2 - x1)

x1=5, x2=9,y1= 8, y2 = 20

Slope = (20 - 8) / (9 - 5)

Slope = 12/4

Slope = 3

How much coffee costing $4 a pound should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.3
AlekseyPX

Answer:

2 pounds of coffee costing $4 should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.30 a pound.

Step-by-step explanation:

Given that coffee costing $4 a pound mixed with 3 pounds of coffee costing $4.50 a pound . we have to find the number of pounds of coffee mixed with 3 pounds of coffee costing $4.50 a pound to obtain a mixture costing $4.30 a pound.

Let x be the pounds of coffee mixed.

Cost of coffee of 3 pounds costing $4.50 a pound is 3(4.50)=$13.5

Total weight of mixture=x+3

The cost per pound of the mixture will be the total value of the coffee in the mixture divided by the total weight of the mixture which is 4x+13.5 divided by total weight 3 + x.

∴ A/Q the equation becomes

\frac{4x+13.5}{3+x}=4.30

⇒ 4x+13.5=4.30(3)+4.3x

⇒ 0.6=0.3x

⇒ x=2

Hence, 2 pounds of coffee costing $4 should be mixed with 3 pounds of coffee costing 4.50 a pound to obtain a mixture costing $4.30 a pound.

Keira , larry and gita picked apples at an orchard. keira picked twice as many pounds as larry and 3 times as many as gita. the
Natalija [7]
Number of apples in pounds picked up by Keira = K
Number of apples in pounds picked up by Larry = L
Number of apples in pounds picked up by Gita = G
Total number of apples they picked all together in pounds = 8360
Now from the given question, we know
Number of apples picked up by Kiera = 2L
So
K = 2L
L = K/2
Again Kiera picked up 3 times as many apples as Gita picked.
So,
K = 3G
G = K/3
Now if we add all the apples in pounds picked up by the three of them.
Then
K + L + G = 8360
K + (K/2) + K/3) = 8360
(6K + 3K + 2K)/6 = 8360
11K/6 = 8360
11K = 8360 * 6
11K = 50160
K = 4560
Then
L = K/2
   = 4560/2
   = 2280
G = K/3
   = 4560/3
   = 1520
Now we can say that
Kiera picked 4560 pounds of apple
Larry picked 2280 pounds of apple
Gita picked 1520 pounds of apple
