Answer:

Step-by-step explanation:

This is a proportion problem. I think you just lost a zero.

12/100 = 9/x Cross multiply

12x = 100*9 Combine the right.

12x = 900 Divide by 12

12x/12 = 900/12

x = 75 grams

So if you put 75 grams of tasty Oats in a bowl and covered it with milk the cereal would give you 9 grams of Protein.

1 gram of Tasty Oats cereal contains 12/100 = 0.12 grams of protein.

1 gram of Cornbits contains 5/45 = 0.11 grams of protein.

By the narrowest of margins the Tasty Oats has more protein in it.

Draw the figure with their measurements and find their volume

babunello [35]

1) Volume = L × W × H = 8 × 3 × 5 = 120 m³

2) Volume = s³ = 17³ = 17 × 17 × 17 = 4913 cm³

3) Volume = s³ = 30³ = 30 × 30 × 30 = 27000 cm³

4) Volume = L × W × H = 13 × 5 × 7 = 455 cm³

5) Volume = s³ = 15³ = 15 × 15 × 15 = 3375 cm³

Formula's applied:

(a) Volume of rectangle: Length × Width × Height

(b) Volume of Cube: (side)³

Answer:

3*r = 3

Step-by-step explanation:

$\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r$ 6 is a solution.

$3*r=3\\\r =\dfrac{3}{3}\\\\r = 1\\$

6 is not a solution.

$7r = 42\\\\r =\dfrac{42}{7}\\\\r = 6$
