The recipe says he needs 450 grams of rice for 6 people
Fynjy0 [20]

Answer:

1.35kg

Step-by-step explanation:

450g : 6 people

x : 18 people

To get from 6 to 18, multiply by 3 so do the same to the other side

450 × 3 = 1350g

To convert from g to kg divide by 1000

1350 ÷ 1000 = 1.35kg

= 6 / (1/4)
= 24 patches.

So a total of 24 patches Marcus used.

What is the length of the diagonal, ddd, of the rectangular prism shown below?
ad-work [718]

Answer:

≈ 9.6 units

Step-by-step explanation:

<em>Refer to attachment</em>

The diagonal d is the hypotenuse of right triangle with sides of 5 and a

The line a is the hypotenuse of the right triangle with the sides of 2 and 8.

<u>So, as per Pythagorean theorem:</u>

  • d² = 5² + a²
  • d²= 5² + 2²+ 8² = 25 + 4 + 64 = 93
  • d² = 93
  • d = √93
  • d ≈ 9.6 units (rounded to the nearest tenth)
