15+ Points for BEST Answer!

Stells [14]

Answer: 306in^3

method: I would split the cross-section (the trapezium at the front) into two shapes. You first have your rectangle with dimensions of 4 and 7, and your triangle with dimensions of height 4 and base 3 (10 - 7 = 3). 4 × 7 = 28in^2, 4 × 3 = 12, 12 ÷ 2 = 6in^2. The total surface area of the cross-section is therefore 6 + 28 = 34in^2. Now, to find the volume, you just multiply that by 9 which is 306in^3, which is your answer. I hope this helps!

The owner of a shop wants to mix cashews and pecans to make 8 kg of mixed nuts worth $7.25 per kg. If the price of cashews is $8

noname [10]

Answer:

6 kg pecans,

2 kg cashews.

Step-by-step explanation:

Let x be the weight of cashews and y be the weight of pecans in kg.

We have been given that the owner of a shop wants to mix cashews and pecans to make 8 kg of mixed nuts. We can represent this information in an equation as:

$x+y=8...(1)$

We are also told that the mixed nuts worth $7.25 per kg, so the price of 8 kg of mixed nuts will be $\$7.25\times 8=\$58$ .

Since the price of cashews is $8.00 per kg and the price of pecans is $7.00 per kg, so we can represent this information in an equation as:

$8x+7y=58...(2)$

Now we will use substitution method to solve system of equations.

From equation (1) we will get,

$x=8-y$

Substituting this value in equation (2) we will get,

$8(8-y)+7y=58$

$64-8y+7y=58$

$64-y=58$

$64-64-y=58-64$

$-y=-6$

$y=6$

Therefore, the owner should take 6 kg of pecans.

Upon substituting $y=6$ in equation (1) we will get,

$x+6=8$

$x+6-6=8-6$

$x=2$

Therefore, the owner should take 2 kg of cashews.
