One serving of soybeans contains 14 grams of protein and 8 grams of fat. One serving of rice contains 4 grams of protein and 1/2

mina [271]

Answer: 1.8 servings of soybean and 1.2 servings rice will be needed.

Step-by-step explanation:

Let x be the number of soybeans and y be the number of rice.

Then , According to the question , we have

$14x+4y=30\\\Rightarrow\ 7x+2y=15..................................(1)\\\\ 8x+\frac{1}{2}y = 15\\\Rightarrow\ 16x+y=30.............................(2)$

Multiply 2 on both the sides of equation (2), we get

$32x+2y=60................................(3)$

Subtract equation (2) from equation (3), we get

$25x=45\\\\\Rightarrow\ x=1.8$

Put x = 1.8 in equation (2), we get

$16x+y=30\\\\\Rightarrow\ y=30-16x\\=30-16(1.8)=1.2$

Hence, 1.8 servings of soybean and 1.2 servings rice will be needed.

1) A triangular prism has a base measuring 8 inches and a side measuring 5

Kruka [31]

Answer:

24 cubic inches

Step-by-step explanation:

Whenever you are finding the volume you have to multiply by two plus a number times two. For example, since there is two depths, you have to multiply 3 by 2 plus the next number. Then, since there is two sides, you multiply 5 by 2 plus the next number. Finally, since there is only one base, you don't have to multiply by two.

(3×2)+(5×2)+8=24

Hope I explained well enough for you to understand.
